Book Marketing – Understanding the Importance of Branding

Book Marketing – Understanding the Importance of Branding

Branding in the library world is as important as the business world. This post identifies its importance to writers. 

Branding is the nuanced art of creating a memorable impression on consumers by giving shape to your brand. Before it was defined as just a name, symbol, slogan, sign, or design. Now it is broader, with more aspects. It helps your customers and clients to distinguish your brand from other brands and know exactly what they can expect from you.

Ages ago, authors did not need to promote themselves on social media. Shakespeare never needed to promote Hamlet on Instagram, and Ernest Hemingway did not need to create dynamic content on Facebook to reach viewers.

But now reaching people without promoting yourself is quite impossible. But definitely, you need to know what to promote. And here ‘ME’ is not a satisfactory answer. You need to establish yourself and your literary work as a brand. That is why book marketing and branding are necessary for writers. Good branding helps you to connect with your audience, deliver your message, and create a positive value about your brand in your target audience’s mind. To learn more, keep reading.

A strong brand’s goals are to communicate the message effectively, personally resonate with your target demographic, inspire the customer to purchase, and build loyalty.

It Helps You Find Your Audience

Brands are easily tracked by the readers who are the main customers of writers. They buy brands. But branding is not always getting prioritized over your competitors. It is creating value for your customers. It is solving a problem.

Branding helps you to reach your consumers to get you connected with them. It exists to help you get recognized. When your readers discover your literary works, it motivates them spiritually and helps them solve their issues and receive mental peace. Brand recognition helps to create loyalty in customers and helps you live in their hearts and minds. Also, once you get a loyal fan base, they will also start marketing for you, which can build your audience even more.

It Tells the World What You’re About

Branding not only gets you loyal customers but also helps you to clearly deliver your message to them. A quality brand gives the consumers something to think about and helps them improve themselves as humans. Once they understand your value they will start reaching to you on their own. Because they value what you value.

A writer puts their soul into their literature. It is their form of communicating, and they definitely want people to know what they think. Branding plays a key role here in bringing together writers and readers. This makes the consumers feel like they’re a part of something significant and not just a cog in a wheel.

It Brings Your Purpose Into Focus

Strong branding helps you make a positive impression among your consumers. Every writer has a purpose. Some write fictional stories to make people understand what magic is inside their minds. Some write comedy stories to make people laugh. Some write biographies and historical books to educate people.

Some really want you to understand love by writing romantic novels. Genres play a big role in writers’ lives. If they can promote their piece well, it will bring in the target audience and fulfill the writer’s purpose.

Surely the world has witnessed thousands of love stories, but branding yours can get your story into the world.

It Gives You Guidance Going Forward

A well-executed brand has a lot to say other than just promoting. Even the greatest brand can even get better by rebranding. If you already brand your writings but want to add different features, values, and colors to them, you can. Rebranding is also very important in this ever-changing world.

Branding helps you to know your directions. It navigates you to make decisions and adapt to the new cultural changes. Ten years ago, love stories might have been really technologically far-fetched. It would be hard to relate to stories like that now. But if you incorporate technology and how to use it to enhance love, people will relate to it and to your writings. You need to brand yourself that way as well.

It Sustains Your Career Over the Long Term

It has already been established that branding helps you to reach out to your consumers and motivate them to buy your products. The stronger your brand is, the more it will expand and reach more people. The author of the Harry Potter series, J.K. Rowling, created her brand with uniqueness and kept on promoting herself to the world.

Even though the series ended quite a while ago, people of all ages still talk about it and appreciate it. A successful brand makes the readers keep coming. They not only still buy her books but also the accessories related to them. This actually helps to generate a huge business. Now not only does she make money, but people from all corners of the world make a living selling product related to her stories.

She not only created a platform for her career but also gave a platform to millions of other people to create theirs.

A Few Final Words

You may be convinced that you should brand your work. But it is not that easy, and you might not be as successful as you’d like for a long time. Still, never give up hope. Try to put out some kind of content on a daily basis. And since humans learn by doing, try to diversify your output and improve your techniques.

A brand doesn’t limit you. So keep exploring many aspects of life and publishing your thoughts about it. We hope these suggestions come in handy for you.

Never give up!

Gemini is a digital currency exchange and custodian that allows customers to buy, sell, and store digital assets. It is a New York trust company that is regulated by the New York State Department of Financial Services (NYDFS) and was founded in 2014 by Cameron and Tyler Winklevoss (the famous Winklevoss brothers who were cofounders of Facebook).

Gemini Commission Fees

One of the key benefits of Gemini is its low commission fees. It is highly competitive among all the brokers. For example the charges for using its Active Trader application is 0.35%. This is very low considering that many exchanges usually charge upwards of 0.5%. For example Binance SG charges 0.60%.

Due to the low fees of Gemini (Active Trader), it is useful for people who are either trading frequently or trading in small amounts.

It is important to always use Active Trader (rather than the basic interface), as it has lower fees.

Gemini Singapore Review

Gemini is extremely fast for signing up. You can signup online within minutes, using Singpass to fill in personal details automatically.

Funding is using Xfers FAST transfer, but it is not subject to the $30k annual limit since it is considered a direct Xfers transfer. For this reason, Gemini is a viable option for those who have maxed out the Binance SG Xfers annual limit.

The fund transfer speed via Xfers FAST is quite fast (pun unintended), usually within minutes.

The website interface of Gemini has an excellent design, and is extremely user friendly.

Gemini Minimum Deposit

There is no minimum deposit for Gemini, and there is also no minimum number of coins or tokens you need to purchase. One can buy as low as just a fraction of Bitcoin.

Is Gemini Safe?

This is the most frequently searched question. Firstly, Gemini is a New York trust company that is regulated by the New York State Department of Financial Services (NYDFS). The official NYDFS press release for Gemini can be found here.

Secondly, The New York Times has reported that Gemini is trusted by Ari Paul, of the hedge fund BlockTower Capital, who deals in virtual currency.[9] According to reports by both Bloomberg News and Fortune magazine, Gemini was the first exchange to launch bitcoin futures contracts in December 2017. Fortune reported that Chicago Board Options Exchange (CBOE) uses Gemini “as the basis for the daily settlement for the bitcoin futures”.[10]

With any investing, there is always some risk, so do your research carefully before investing using any exchange!

Last few months to mine Free Pi Coins (Referral Code: math88pi)

Pi Network Invitation Code: math88pi

I am sending you 1π! Pi is a new digital currency developed by Stanford PhDs, with over 10 million members worldwide. To claim your Pi, follow this link https://minepi.com/math88pi and use my username (math88pi) as your invitation code.

It is literally the last few months to mine Pi Coins, Mainnet is launching in estimated Q4 2021 which is just a few months away.

Pi Network has a halving procedure in place, similar to Bitcoin. Basically it means that, the mining rate will reduce by half  when a certain milestone is being hit (usually in terms of number of members). Eventually, the mining rate may even hit zero. This means Pi Coin eventually has a finite supply, just like Bitcoin.

We have a detailed review of Pi Network and Pi Coins in a previous blogpost.

Pi Wallet will be released on 31 March 2021

On the Pi Network’s official Twitter page, they announced that they will be releasing the Pi wallet on the Testnet with Test-Pi on March 31, 2021.

This is quite an achievement, Testnet is usually just one step behind Mainnet. For example, Ethereum has several Testnets such as Rinkeby Testnet. The Testnet can act as a test or experiment to see if there are any bugs, before rolling out the Mainnet which contains the actual Pi coins.

Pi network vs Bee network

In the previous blogpost, we detailed some reasons why Pi network is likely to be legit.

Unfortunately, the same cannot be said for Bee network:

  • Bee network is created by anonymous/unknown people.
  • Bee network is just a “clone” of Pi Network in many ways, up to their White Paper.
  • Not sure if Bee network is a legitimate blockchain project, or just one that is trying to ride on the waves of Pi Network.

Hence, currently, we recommend Pi Network but not Bee Network.


Disclaimer: The opinions on Pi Network expressed in this blog post is for general informational purposes only and are not intended to provide specific advice or recommendations for any individual or on any specific security or investment product. It is only intended to provide information on Pi Network Referral Code. In particular, this blog post is not a substitute for obtaining advice from a qualified investment advisor.

Pi Network Referral Code: math88pi

In view of the upcoming Pi day (3.14), this topic of Pi Network is quite appropriate. In this blog post, we will share about Pi Network, what it is, and more.

Pi Network Invitation Code: math88pi

I am sending you 1π! Pi is a new digital currency developed by Stanford PhDs, with over 10 million members worldwide. To claim your Pi, follow this link https://minepi.com/math88pi and use my username (math88pi) as your invitation code.

Pi Network Review

Pi Network is an upcoming blockchain, with idea similar to Bitcoin, but yet with certain differences:

  • Pi Network uses the Stellar Consensus Protocol, while Bitcoin uses Proof of Work.
  • Pi Network is currently still in the early phases, meaning that it is not available on the “Main Net” yet, or on any exchange. Bitcoin is already very established as of 2021, even recognized by major institutions and banks.

Is Pi Network Safe / Is Pi Network Legit

While it is impossible to answer with 100% certainty, one can list at least 3 reasons why Pi Network is legit:

  1. Pi Network is listed on the Apple App Store. It is known that “Apple evaluates every app in detail before it’s available in the App Store to make sure that it doesn’t contains viruses.”
  2. Pi Network is created by real known people (Stanford PhDs: Dr. Nicolas Kokkalis and Dr. Chengdiao Fan) who put their real name upfront. Their identities are verified by Stanford Daily, which is the official student-run, independent daily newspaper serving Stanford University.
  3. No money is involved in using Pi Network app. No credit card details are needed. Hence, it is impossible that Pi Network is trying to scam money since no money is involved.

Is Pi Network Worth Anything

This is another popular question, on whether Pi Network is worth it. Firstly, Pi Network only takes few seconds per day, to tap the mine button. Hence, the total time wasted is very minimal.

Secondly, once Pi Network goes live on the Main Net, it has to be worth something non-zero. Many YouTubers have analyzed its worth (Pi Network price predictions), the below video has quite a mathematical estimate of what Pi Coin is worth.

Pi Network Referral Link: https://minepi.com/math88pi

Pi Network Invitation Code: math88pi

Pi Network Mining

Pi Network coins are able to be mined on a mobile phone. They are very unlike the Proof of Work algorithms which require massive amounts of electricity and computing power. In fact, the coins can be mined without WiFi or running in the background.

What is happening at this stage is actually “pre-mining”, which is consistent with the Stellar Consensus Protocol (SCP):

Pi Network differs from traditional cryptocurrencies in that the coins are “pre-mined” or pre-generated from the start. When you initiate mining on the Pi Network app, you are simply being a distributed a set amount of coins per hour. Because the coins are pre-generated, your phone doesn’t do any heavy computational tasks, and power impact is minimal.

Medium: https://medium.com/@kona.kona/cryptocurrency-for-everyday-people-from-stanford-pi-network-9d743d1ddfd2

The mining of Pi Coin has a halving stage, just like Bitcoin. Eventually, the mining rate could even fall to zero. This helps to reduce inflation.

Buying property off plan

Obviously the prices of buying your property off plan will vary. Factors that can increase the price of your off plan property are location, the size of the property, access to local towns/cities and airports and the legal fees.The size of the property can effect the price, larger properties cost more than smaller ones to build.The location of your spanish property can effect the price that you pay. The location can effect the price of your off plan property, if it in a tourist area then it may cost more to build there however it can also generate good renting prospects as some properties in the south of spain only need to be rented out for around 18-20 weeks a year in order to cover the mortgage, that leaves you with a minimum of 32 weeks in the sun. One point you should always keep in mind when looking at the price of a property is the lawyers costs, the registration costs and the notary costs. This can range from being anywhere between 5% and 10% of the original cost of the property.

Advantages of Buying Off Plan:

Some advantages that you can find from buying your spanish property off plan are:

That you only pay the amount that the property was valued at when you first signed the contract for example should you buy a house for €100,000 and then by the time that the property has been built it has increased in value to €130,000 you still only have to pay €100,000.

Should you change your mind about the area or the property then usually you have the option to sell your property prior to completion and the writting of the deeds (escritura). However before you sign the contract to start building your property you should ask if this service is available to you because it is not always.

Buying an off plan property is usually about 30% cheaper than buying a ready built or resale property. It is generally much simpler to buy off plan in terms of searching for the right property for you. This is because you can see straight off what the property is going to be like through arctitectual drawing unlike when you go to view a resale house they can be very diferent to what they look like in picures on the website or prospects. Also with off plan buying you have can change the aspects of the house that are not to your taste or that you had imagined to be different in your dream house.

There can be advantages to buying your property off plan but through “ready made” plans. By doing it this way you can get all the benefits of buying off plan but there is less stress placed upon you to come up with a design for your property. The downside to this is that there may well be quite a few properties that look very similar to yours. It does also mean that there should be less cost with architects because the plans are already there.

GameStop Short Interest

GameStop Short Squeeze is recently a very hot topic in the USA, and refers to the short squeeze of the stock of the American video-game retailer GameStop and other securities that took place on various stock exchanges, causing major financial consequences for certain hedge funds. It has been reported in many news outlets, including CNBC, BBC, and Reuters.

There are a few free sites to check out the GameStop current short interest, or the GameStop short interest today. Short interest is the number of shares that have been sold short but have not yet been covered or closed out. A related concept, short interest ratio, represents the number of days it takes short sellers on average to cover their positions, that is repurchase all of the borrowed shares.

GameStop Short Interest Data

  1. One of the sites to check out the current GameStop Short interest is:
    https://isthesqueezesquoze.com/. It uses data from Ortex or S3Shortsight.
  2. Another site is the Twitter Page of S3 Partners, which is a FinTech company. They often publish the statistics for GameStop (GME) short interest on a daily basis.
  3. A third source is Ihor Dusaniwsky’s Twitter Page. Ihor is the Managing Director of Predictive Analytics at S3 Partners. He posts GameStop Short Interest information on a regular basis, including some explanations to beginners.

Note that there are two ways to calculate short interest (SI):

  1. SI = shares shorted / (float). This value can exceed 100%.
  2. SI = shares shorted / (float + shares shorted). This includes the “synthetic longs” created by short selling, and will be a value between 0% to 100%.

GameStop Short Squeeze

Do also check out the Twitter Page of Michael Burry, where he posts information about GameStop Short Squeeze, GameStop Gamma Squeeze and more. Michael Burry is a famous investor and inspired the main character in the movie “The Big Short”.

Ethereum in real life (Duke University is teaching Ethereum)

Ethereum has started to see many actual use cases in real life. For instance, major companies like Amazon, Microsoft, Google, Visa are all starting to adopt Ethereum as part of their real life usage.

Ethereum has started to appear in education as well. Duke University (one of the top universites in the USA), has started teaching modules of “Ethereum and Smart Contracts” as part of the syllabus.

Course description (Ethereum and Smart Contracts course in Duke University):

“Learn how to develop smart contracts and decentralized applications on the Ethereum Blockchain as well as history and trends of Ethereum itself. Ethereum is the most promising decentralized smart contract platform, and blockchain developers are in high demand. Learning these skills will give you a leg up in the blockchain world, especially in the Ethereum ecosystem. We will cover Ethereum (the platform), Solidity (the programming language), Truffle (the developer framework), and web3.js (the front-end library). Preference: some blockchain/cryptocurrency understanding. Prerequisite: basic programming skills.”

Trinity College of Arts and Sciences at Duke University


Ethereum Book

Learning blockchain technology should be a very marketable skill in the near future. Currently, there are two main ways to learn it, through online courses or through books.


Mastering Ethereum: Building Smart Contracts and DApps

The book above is authored by Dr Gavin Wood, who was the creator of the Solidity language and cofounder of Ethereum.

Ethereum Real Life Applications

Recently, the blockchain Ethereum is starting to gain widespread acceptance, many major companies such as Microsoft, Google, Amazon are already using it.

In terms of publicity, Ethereum is still behind its more famous cousin “Bitcoin”, but that should change in the near future. In fact, many people have postulated that a “flippening” may happen where Ethereum takes over Bitcoin as the cryptocurrency with the largest market cap.

In this blogpost, we list the real life applications and uses of Ethereum, using official sources as far as possible. That is, if Google is using Ethereum, we will try to point to the official Google website instead of a third party news site. Otherwise, we will only use very reliable third party sources such as Forbes, etc.

Amazon Ethereum Blockchain

This is very recent news, on Dec 21 2020. Amazon Managed Blockchain now supports Ethereum. With Amazon Managed Blockchain, AWS (Amazon Web Service) customers get secure networking, fast and reliable syncs to the Ethereum blockchain, durable elastic storage for ledger data, encryption at rest and transport, and secure access to the network via standard open-source Ethereum APIs.

Official Amazon Ethereum Blockchain news: https://aws.amazon.com/about-aws/whats-new/2020/12/amazon-managed-blockchain-supports-ethereum/

Google Cloud & Ethereum

Ethereum can inter-operate with Google Cloud’s enterprise cloud data warehouse (BigQuery) via oracle middleware (Chainlink). At a high level, Ethereum Dapps (i.e. smart contract applications) request data from Chainlink, which in turn retrieves data from a web service built with Google App Engine and BigQuery.

Other Ethereum use cases

A full list of companies using (or interested in using) Ethereum can actually be seen on the Enterprise Ethereum Alliance website, under the members section. We can see that many big name companies are part of the Enterprise Ethereum Alliance, including:

  • Accenture
  • Baidu
  • Dell (Boomi)
  • Ernst & Young
  • Intel
  • PricewaterhouseCoopers LLP
  • Standard Chartered Bank
  • VMware, Inc.

It is interesting to note that 2 of the “Big Four” accounting firms, Ernst & Young and PricewaterhouseCoopers are interested in Ethereum and smart contracts, which could potentially change the accounting industry.

According to Business Times Singapore, 80% of current accounting tasks will soon be done by machines, displacing humans in most junior finance roles.

Printable Calendar 2021 Singapore

Free printable 2021 calendar Singapore available for download in the link below.

MonthlyCalendar-2021

In the 2021 Monthly Calendar Singapore (printable) attached above, we see that Chinese New Year falls on 12 February, which is a Friday. Hence there is a long weekend stretching from 12 February (Friday) to 14 February (Sunday).

Another long weekend we can see in the Singapore calendar 2021 with public holidays, is the Good Friday long weekend starting on 2 April 2021 (Friday) to 4 April 2021 (Sunday).

The next long weekend is potentially the Labor Day long weekend, as can be seen in the above Singapore calendar 2021 with public holidays. Labor day (1 May 2021) falls on a Saturday, hence it is up to one’s employer to offer a day off-in-lieu.

The second last official long weekend should be the National Day public holiday, ranging from 7 August (Saturday) to 9 August (Monday).

Lastly, the last long weekend in 2021 according to the printable calendar is Christmas, ranging from 25 Dec 2021 (Saturday) to 26 Dec 2021 (Sunday), and potentially 27 Dec 2021 (Monday) if there is a off-in-lieu.

NIO ES8 Aluminium: Li Bin’s Genius Aluminum Strategy (no other country can copy NIO!)

Summary: There are only 3 countries in the world that can make more than 10 million all-aluminum Electric Vehicles per year.  NIO happens to be in one of them that can make 100 million per year, and Li Bin has taken full advantage of this fact. No other country can copy NIO at a large scale since there is simply not enough aluminum (unless heavy imports are done which will further drive up the price of aluminum).

Two of the above 3 countries have to use up their entire aluminum production to achieve 10 million all-aluminum cars, which is not practical since there are other important uses for aluminum besides cars.

NIO ES8 Aluminium

NIO’s CEO Li Bin has made the genius decision for the NIO ES8 to be completely aluminum, or to be precise, the ES8 uses 96.4% aluminum, the highest percentage of aluminum used in an all-aluminum body in mass production worldwide.

The clear benefit of aluminum over steel is that it is lighter. The NIO ES8 uses an all-aluminum frame, which is about 40% lighter than traditional steel bodies (density of steel 7.8 g/cm3> aluminum 2.7 g/cm3).

With a lighter body, an all-aluminum car would be able to travel further than a steel car per unit of battery power. It is very clear that an all-aluminum car is superior to a steel car.

The NIO ES8’s body-in-white weight is 13.6% of the total vehicle weight, which is 2460 kg. That means, the weight of aluminum in one NIO ES8 car is  approximately 13.6%x2460 = 335 kg.

The genius of Li Bin’s strategy is that no country can copy this all-aluminum strategy on a large scale, as shown in the calculations below. To further add to this, Li Bin must have thought and planned for this very early, well before the factory of ES8 was built.

How many All-Aluminum Cars can each Country make per year

The yearly aluminum production of each country is taken from Wikipedia: List of countries by primary aluminium production.

China produces 36,000,000,000 kg of aluminum in a year. Since one NIO ES8 contains 335 kg of aluminum, that means that:

China can make 36,000,000,000/335 = 107 million aluminum cars per year

Similar calculation for India, India produces 3,700,000,000 kg of aluminum in a year. Since one NIO ES8 contains 335 kg of aluminum, that means that:

India can make 3,700,000,000/335 = 11 million aluminum cars per year

We do the other calculations in the table below. Note that India and Russia have to use up 100% of their aluminum in order to exceed the 10 million aluminum cars target per year. Other countries cannot make more than 10 million all-aluminum cars even if they use up all their aluminum production.

Rank Country/Region Aluminium Production (thousands of metric tons) No. of Aluminum Cars per Year (millions)
1 China 36,000 107
2  India 3,700 11
3  Russia 3,600 11
4  Canada 2,900 9
5  United Arab Emirates 2,700 8
6  Australia 1,600 5
7  Bahrain 1,400 4
8  Norway 1,300 4
9  United States 1,100 3
10  Saudi Arabia 932 3

Number of all-aluminum cars each country can make at the maximum (per year).

Shaoqing Ren NIO: The Genius of Autonomous Driving

Ren Shaoqing NIO – Top Researcher in Autonomous Driving

Not many people know this, but NIO car manufacturer’s head of AI, Ren Shaoqing (任少卿) is an absolute genius in the field of autonomous driving. In this blog post, we will detail facts about Dr Ren Shaoqing and his research in self driving and autonomous driving technology. We will also introduce other top researchers in the field of autonomous driving. All our sources are from Google Scholar and other trusted sources.

Ren Shaoqing NIO – the secret weapon of NIO Autonomous Driving

Everyone knows that the main trumps of electric vehicles are clean energy, and autonomous driving. NIO has managed to hire the top researcher in the field of autonomous driving. They are quite low profile about it, not many people know about this at the moment.

Just click on the Google Scholar (Autonomous Driving) link, it will show you the full ranking of the top researchers in the field of autonomous driving, ranked by the official Google Scholar algorithm according to citation count.

The top 5 researchers in the field of Autonomous Driving, ranked by the official Google Scholar page.

Just look at the top researcher in the list, it is Dr Ren Shaoqing of NIO, with a whopping 111,396 citation count (as of Dec 2020). Citation counts are a way of measuring the impact of a researcher’s work. Basically, the more citation counts means the more people are noticing and citing the researcher’s papers. Ren Shaoqing’s citation count of 111k is typically 10 times more than a Full Professor at most universities.

In terms of quantity of citations, it is clear that Ren Shaoqing (NIO’s head of AI), is at the top of the game. How about quality of research?

Dr Ren Shaoqing’s research quality is top notch as well!

Ren Shaoqing NIO – Achievements in the field of Autonomous Driving

  • First author paper at NIPS (Conference on Neural Information Processing Systems), which is one of the best conferences in computer science. The paper’s topic is “Faster R-CNN: Towards real-time object detection with region proposal networks”. Real-time object detection is very related to autonomous driving, it helps the car detect objects and obstacles in real time.
  • CVPR Best Paper Award, 2016. CVPR is the premier annual computer vision event comprising the main conference and several co-located workshops and short courses. His co-authored award winning paper is titled “Deep Residual Learning for Image Recognition”.
  • ImageNet Large Scale Visual Recognition Challenge (ImageNet) Competition Winner Award, 2015
  • COCO Detection Challenge Winner Award, 2015
  • Microsoft Research Asia Fellowship, 2014
  • National Scholarship of China, 2010

In case, if anyone is thinking that Dr Ren Shaoqing is just an academic nerd with no business experience, that would be totally wrong! He has business and startup experience as well, he co-founded an autonomous driving software startup Momenta.ai, which grew into unicorn (private company with a valuation over $1 billion) in three years, aiming to help people live a better life with improved safety and efficiency of driving through artificial intelligence.

More of Ren Shaoqing’s achivements in autonomous driving and self driving can be found on his personal website.

Some of the comments on Ren Shaoqing’s personality can be found on Chinese website Zhihu (Chinese version of Quora):

这里的“年轻”除了长相上的嫩,也包括为人处世——完全没有架子。他是个很儒雅的人,手下的团队跟他也很亲近。少卿做事风格看起来不紧不慢、慢条斯理,但论及“拼”,他也是超拼。记得有一段时间,他白天一整天的时间都花在各种会、各种面试上,一直会持续到凌晨十二点之后。这时他也不着急走,而是继续干些得静下心来才能干的工作。早期他主要负责视觉感知研发方面的工作,后来负责了一段时间高速路自主巡航相关的项目,我走的时候还是在负责感知研发。

Translation:

Ren Shaoqing is a young guy, he is very humble with no airs. He is a very refined person, and his team is very close to him. Shaoqing’s style of doing things does not seem to be hurried, his style is slow and steady, but when it comes to “fighting”, he is also super persistent. I remember that there was a period of time when he spent the whole day in various meetings and interviews, which lasted until after 12am midnight. At this time, he did not leave office in a hurry, but continued to do some work that could only be done by calming down in the quiet of the night. In the early days, he was mainly responsible for the research and development of visual perception. Later, he was responsible for the projects related to autonomous driving on highways for a period of time. When I left, he was still responsible for the research and development of visual perception.

It is clear that Ren Shaoqing is one of the brightest stars in this exciting new field of Autonomous Driving!

Ren Shaoqing – the 21st Century Zhuge Liang of Autonomous Driving

Based on Ren Shaoqing’s personality (devoted and extremely hardworking 鞠躬尽瘁, but yet calm and unhurried) and achievements in autonomous driving, he bears close resemblance to a legendary character in Chinese history: Zhuge Liang.

In Chinese history or legend, Zhuge Liang was a famous military strategist and inventor. He is said to invent the first self-driving (or self-walking) cow, called the Wooden Cow Flowing Horse (木牛流马). It was said to be able to walk by itself and was used to transport grain during the Northern Expedition.

The self-driving car (or rather cow), invented by Zhuge Liang, according to legend.

Hence, Zhuge Liang can be said to be the father of autonomous driving or self-driving, according to legend. Will Ren Shaoqing (NIO’s head of AI) become the Zhuge Liang of the 21st Century and invent the perfect autonomous self-driving car?

NIO Book

Currently, there is no NIO book available as history is still being written! We will definitely add them here if books on NIO become available. For a deeper insight into Electric Vehicles and Autonomous Vehicles, there are several great books on Amazon.

(New York Times Bestseller!)


Autonomous Vehicles: Opportunities, Strategies and Disruptions: Updated and Expanded Second Edition

NIO Car Battery Swap Videos

Interesting real life video of NIO car battery swap. Interestingly, the NIO car BaaS battery swap center in Shanghai is right next to its competitor Tesla’s Supercharger! The battery swap section is right at 8:55.

The above YouTube channel is a reliable and unbiased one, not set up specifically to promote NIO. It has been around for years, showing how the channel’s owners who are just in their 40s “retire” in Malaysia. They are currently back in Shanghai, not sure if it is permanent or just temporary to avoid the COVID situation in Malaysia.

By the way, in the video, the people are discussing how a house in Shanghai costing 6 million RMB (or almost 1 million USD) is “cheap”! This shows how rich the people in Tier 1 cities in China are, buying an electric car is no big deal for them, as long as the quality is good.

The video above is another authentic video from a real life NIO owner, performing battery swap in another Tier 1 city in China, Shenzhen. The entire battery swap process takes around 4.5 minutes, provided there is no long queue. This is just as fast or even faster than refilling petrol.

Battery swap can be considered as a moat of the company NIO. It is not easy for other car companies to suddenly switch to battery swapping since that would involve significantly redesigning their car or factory.

NIO cars can also charge the battery the conventional way, in addition to battery swapping. Another advantage of battery swapping is that older NIO car models can easily “upgrade” to a newer battery, for example from 70 kWh to 100 kWh.

Check out NIO’s CEO Li Bin launching the new 100 kWh battery in the video below, just recently in November 2020. The 100 kWh battery is on par with Tesla’s Model S.

Tesla vs NIO (NIO is the only other company to follow Tesla’s “Master Plan”)

Tesla is a famous company founded by billionaire genius Elon Musk. Elon Musk is the CEO and founder of multiple high-tech companies such as Tesla, SpaceX and Open AI.

It is highly recommended for gifted kids and parents to read about Elon Musk and his unique childhood and personal traits. Currently, there is a promotion where you can listen to the bestselling audiobook free if you Try Audible Plus.


Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future (Top seller on Amazon)

NIO vs Tesla

Firstly, we introduce the founder of NIO, Li Bin, as a comparison to Tesla’s Elon Musk. Li Bin was born in a poor cow farmer’s household in Anhui, China. His home did not have electricity until he was around 10 years old. His brilliance was noticed early in life, where he emerged the top scholar in the Anhui province in the Gaokao exams and entered the best university in China, Peking University. In Peking University, he majored in sociology, and minored in law and computer science.

Before NIO, Li Bin has founded or cofounded multiple successful companies, including:

  • Bitauto (易车), a leading provider of internet content & marketing services, and transaction services for China’s automotive industry.
  • MoBike, a bike sharing platform in China.

Under Li Bin, NIO is the only other EV company to follow Elon Musk’s tried and tested Master Plan:

Tesla’s “master plan”, as iterated by Musk in 2006 was: Build sports car. Use that money to build an affordable car. Use that money to build an even more affordable car. While doing above, also provide zero-emission electric power generation options.

Source: Wikipedia

NIO EP9

The first step of Tesla’s “master plan” is to build a sports car. NIO has already built the EP9 car which is one of the world’s fastest supercar. It has broken multiple records, and can reach a top speed of 350 km/h.

NIO EC6

True to the “Master Plan”, NIO has next built more affordable cars, such as the latest NIO EC6. The EC6 is a fully-electric mid-size luxury crossover SUV, just announced in late 2019 by NIO.

NIO vs Tesla China

NIO is initially aiming for a share in China’s enormous EV (Electric Vehicle) market, which is the world’s biggest market for EVs. Subsequently, it has plans to expand into Europe and the rest of the world.

NIO does not have its own factory currently (it has a joint factory with the state-owned JAC Motors in Hefei). This may change in the future. The JAC-NIO factory is impressive, and has up to 97.5% automation rate.  Note that Apple also doesn’t have its own factory, hence not having a factory can’t be said to be a fatal flaw of NIO.

NIO Future Plan and Potential

NIO’s future plan is to produce more models of cars, including two sedans (ET5 and ET7), as well as a minivan (EF9) and another SUV (ES7).

NIO focuses a lot on good service, and provides several unique services, most notably BaaS (Battery as a Service). BaaS allows NIO cars to swap their batteries, which is currently much faster than charging. In addition, most Asian countries, including top tier cities in China, simply do not have enough space for a charging station for each household. Hence, BaaS will be a great differentiating factor which gives NIO an edge over its competitors.

As for NIO’s potential, just watch this video on top 30 most industrialized countries in the world. NIO is the premier high end electric vehicle manufacturer in China, and all signs are pointing to it having a great potential in the future (if things go smoothly).

NIO Moat

A moat is a key competitive advantage that sets a company apart from its competitors. NIO’s first moat is its unique BaaS. Since a car’s model cannot easily change (due to the factories’ fixed specification), should BaaS battery swapping become the trend, NIO will be the sole company that provides it and will have at least a few years’ lead ahead of its competitors.

NIO’s second moat is its infrastructure and domestic home ground advantage. NIO’s autonomous driving system is naturally trained in China’s traffic conditions. Even in the event of slightly inferior autonomous driving technology (which is still highly debatable), the end result would still be better than a top driving system trained in another country’s very different traffic conditions, including different driver behavior and different road signs.

NIO backed by government

Many signs have shown directly or indirectly that NIO is backed by the government. Firstly, JAC Motors with whom NIO has a joint factory with, is a Chinese state-owned automobile and commercial vehicle manufacturer.

Secondly, NIO is the first car company to cooperate with State Grid EV service to build 100 charging and battery swap stations by 2021. This is good news for NIO since the State Grid EV being owned by the State/government has good potential to select excellent locations for the battery swap stations which will further strengthen’s NIO’s BaaS network.

DBS Multiplier Interest Rate Changes

DBS Multiplier Changes

DBS Multiplier has officially announced some changes, effective 1 January 2021. Do check out the official PDF document here.

We also attach the screenshot below for the reader’s convenience.

DBS Multiplier Review

Well, it is clear that the DBS Multiplier changes are not good! Most of the interest rates are heavily affected, especially for the average Singaporean saver. This is not unique to DBS though, most banks in Singapore have slashed their interest rates, including Citibank, CIMB, and others.

For savers who have less than 3 categories transactions (Credit Card Spend, Home Loan Instalments, Insurance or Investments), most likely his/her interest rate will drop to below 1% p.a. This is a halving of the previous interest rate.

DBS Multiplier Minimum Balance

Note that DBS Multiplier has a relatively high minimum balance of S$3,000, and there is a service charge of S$5 if average daily balance falls below S$3,000.


DBS Multiplier Alternative

If you are looking for an alternative to DBS Multiplier, do check out our previous blog post Gigantiq Promo Code: MATH88. Basically, Gigantiq is a capital guaranteed savings plan that offers  interest rate of 1.8% p.a. (previously 2% p.a.). This is much higher than all banks currently, including fixed deposits. Gigantiq is backed by Etiqa, which is the insurance branch of Maybank, the largest bank in Malaysia.

Spyder Typing Delay

Recently, the Spyder IDE faced serious typing delay or lag. Basically, after entering something using the keyboard, it takes almost half a second for it to appear on the screen. The issue can also be described as a typing lag in Spyder.

This seems to have been triggered by the installation of Big Sur OS.

Spyder slow on Mac

After intensive googling, we stumbled upon this Github page detailing several possible solutions.

The one that worked for us was installing pyqt and pyqtwebengine. Basically, type the following commands in the terminal:

pip install PyQt5
pip install PyQtWebEngine

The above solution should be very safe since it is just installing Python packages.

Spyder lagging

The above solution helped to solve the troubling issue of Spyder lagging. Since Spyder uses Qt for its GUI, it is critical to keep the various Qt related packages updated / at the correct version. This may be the reason why installing PyQt5 and PyQtWebEngine helps to remove the lag in Spyder.

Spyder very slow

There seems to be many reasons, other than the above, that can result in Spyder being very slow. One tip that is useful, is never update to the latest version of Spyder, Mac OS, or Anaconda immediately once it is released, unless it is absolutely necessary. Most of the bugs appear in the newest releases, and can cause multiple problems including making Spyder very slow. By updating at a later date, most of the bugs would have been solved by then and it is a much safer approach.

Previously, updating to the latest Spyder 4.1.5 also caused several problems, including lag, slowness or even Spyder simply just crashing.

My All 2020 Mathematics A to Z: Wronskian

Great interesting post on Wronskian, which is widely used in the study of differential equations. Wronski is an eccentric genius, who was once forced to leave his post at the Marseille Observatory after his theories were dismissed as “grandiose rubbish”, according to Wikipedia.

nebusresearch

Today’s is another topic suggested by Mr Wu, author of the Singapore Maths Tuition blog. The Wronskian is named for Jzef Maria Hone-Wroński, a Polish mathematician, born in 1778. He served in General Tadeusz Kosciuszko’s army in the 1794 Kosciuszko Uprising. After being captured and forced to serve in the Russian army, he moved to France. He kicked around Western Europe and its mathematical and scientific circles. I’d like to say this was all creative and insightful, but, well. Wikipedia describes him trying to build a perpetual motion machine. Trying to square the circle (also impossible). Building a machine to predict the future. The St Andrews mathematical biography notes his writing a summary of “the general solution of the fifth degree [polynomial] equation”. This doesn’t exist.

Both sources, though, admit that for all that he got wrong, there were flashes of insight and brilliance in his work. The St Andrews…

What happens if you fail PSLE?

The PSLE (Primary School Leaving Examination) is a momentous event in the Singapore education system, where all Primary 6 (12 year old students) sit for the national exam that will determine their future secondary school (or even beyond, in the case of Integrated Programme).

PSLE is not everything

Despite the overall importance of PSLE, it has to be noted that PSLE is not everything. There are countless stories of late developers who later pursued successful careers, despite a bad PSLE Score.

Read about the miracle story of a student who scored 181 for PSLE (technically still a pass grade, but considered not so good), but later entered NUS Medicine, the most prestigious course in Singapore.

PSLE fail go where?

This seems to be a frequently asked question. There are still many options, one of them is NorthLight School, which was featured in the Straits Times. NorthLight School is a specialized school that takes in students who fail their PSLE. Each year, the intake of NorthLight School is around 200 students.

In 2009, Assumption Pathway School was also set up to take in students who fail PSLE, ensuring that students have a place to go to further their education.

After graduating from NorthLight School or Assumption Pathway School, around 45% of students go on to enter Institutes of Technical Education (ITE). After that, they can move on to Polytechnics.

What happens if you fail one subject in PSLE?

Unlike O levels, where there are quite severe consequences for failing critical subjects like ‘O’ level English or Maths, there is no penalty specifically for failing a certain PSLE subject.

According to experienced parents at Kiasuparents, the only problem of failing one subject in PSLE is that it will drag down the overall PSLE T-score. It has been estimated that failing one subject in PSLE would most likely cause the overall score to be below 200 (which can still enter many neighborhood secondary schools).

PSLE takes into account all 4 subjects. So even if you failed English or Chinese or any subject, it doesn’t matter. what matters is your combined score that determine whether you go express or normal academic.

Source: Kiasuparents

Hence, if the student does well for other subjects, it is not a big problem for failing one subject in PSLE, be it failing PSLE English, failing PSLE Chinese, or failing PSLE Math.

Bad PSLE results

It is actually quite rare to fail PSLE outright (around 98.4% of students pass and make it to secondary school). However, it is quite common to get a ‘bad’ PSLE results or a lower score than one expects.

When one gets a bad PSLE result, or fail PSLE (one or all subjects), the important thing for the student is not to get overly disheartened. It could well be the case that the student is a late developer, or that certain negative events out of the student’s control have impacted the student’s family, which resulted in the bad PSLE results.

Do check out this other inspirational story, of a student who scored 105 for PSLE, but later graduated from NUS with a Master of Architecture degree. The important thing is not PSLE grades (PSLE is not everything), but rather the character traits of a student such as being determined and hardworking.

PSLE 2020 Results and PSLE Cut Off Point 2020

The 2020 Primary School Leaving Examination (PSLE) results will be announced on 25 November 2020 (Wed). Given the ongoing COVID-19 situation, students will receive their results from their respective primary schools – in their individual classrooms instead of gathered as a cohort in the school hall – from 11.00am on 25 November 2020.

Source: MOE Website

PSLE 2020, 2021 Cut off point

The exact cut off point is not out yet, but based on previous years’ cut off points, we give some estimates of the PSLE 2020 Cut off point (for entry to secondary school in 2021).

IP schools cut-off point

The most popular schools are definitely the IP (Integrated Programme) schools, since they are the most prestigious, and also students get to skip the O Levels which is a major source of stress for the students and their parents.

IB schools are also very popular, since it is well known that the IB syllabus is easier to score than the ‘A’ levels.

‘S’ Tier IP Schools PSLE Cut off point

The ‘S’ Tier IP and IB schools are:

  • Hwa Chong Institution
  • Raffles Girls’ School (Secondary)
  • Methodist Girls’ School (Secondary)
  • Nanyang Girls’ High School
  • Raffles Institution

These are the top elite schools in Singapore. MGS (Methodist Girls’ School) COP has risen to this level in recent years, while HCI, RGS, RI, NYGH are the traditional top 4 secondary schools. In order to have a secure chance of entering these schools, the estimated COP or cut-off point is around 260, not considering affiliation. In certain years, a high 250s score such as 258 or 259 may also suffice, but it is quite risky.

‘A’ Tier Secondary School PSLE Cut-off point 2020

The ‘A’ Tier top secondary schools are:

  • Dunman High School (IP)
  • National Junior College (IP)
  • CHIJ St. Nicholas Girls’ School (IP)
  • Anglo-Chinese School (Independent) (IB)
  • Catholic High School (IP)
  • Cedar Girls’ Secondary School (IP)

These schools are very close to the ‘S’ Tier elite schools mentioned above. For these schools, traditionally, a score of around 255 and above is the usual COP or cut off point.

Note that some of the above good schools also have an ‘O’ level track whose COP (Cut-off point) is typically around 5 points lower, or around 250.


PSLE Express Cut off point 2020

Historically, the PSLE cut off point for express stream is around 188. For example, the following schools (express stream) have their PSLE cut-off point set at 188, for the 2020 secondary school intake:

  • Assumption English School
  • Bartley Secondary School
  • Bedok Green Secondary School
  • Bendemeer Secondary School
  • Boon Lay Secondary School
  • … and many more, all the way to Yuhua Secondary School and Yuying Secondary School.

My All 2020 Mathematics A to Z: Velocity

V for Velocity! Excellent exposition on velocity, and especially on phase space by Nebus Research blog.

nebusresearch

I’m happy to be back with long-form pieces. This week’s is another topic suggested by Mr Wu, of the Singapore Maths Tuition blog.

Color cartoon illustration of a coati in a beret and neckerchief, holding up a director's megaphone and looking over the Hollywood hills. The megaphone has the symbols + x (division obelus) and = on it. The Hollywood sign is, instead, the letters MATHEMATICS. In the background are spotlights, with several of them crossing so as to make the letters A and Z; one leg of the spotlights has 'TO' in it, so the art reads out, subtly, 'Mathematics A to Z'. Art by Thomas K Dye, creator of the web comics Projection Edge, Newshounds, Infinity Refugees, and Something Happens. He’s on Twitter as @projectionedge. You can get to read Projection Edge six months early by subscribing to his Patreon.

Velocity.

This is easy. The velocity is the first derivative of the position. First derivative with respect to time, if you must know. That hardly needed an extra week to write.

Yes, there’s more. There is always more. Velocity is important by itself. It’s also important for guiding us into new ideas. There are many. One idea is that it’s often the first good example of vectors. Many things can be vectors, as mathematicians see them. But the ones we think of most…

What Are the Best Online Math Tutoring Websites?

What Are the Best Online Math Tutoring Websites?

Many people find math to be a difficult subject to excel in as compared to any other subject. However, it is not the case at all. Math only needs one to have a positive attitude, an excellent tutor, and lots of practice. It is quite an interesting subject to learn and proves to be handy on many different occasions.

Looking for a tutor online to help you figure out your math problems can be quite a daunting task. It is relatively easy to get the wrong service provider when you need to find help for your child. You need to check the best online math tutoring websites, which will help you find the best services online for your child or student. It is quite common to find a service provider who will not give you the value you desire online. It would help if you took into account reviews, which will guide you to make the best decision.

The Best Online Math Tutoring Websites

Here is a list of the best available math tutoring websites online:

1.     Princeton Review

The Princeton Review is recognized as one of the best platforms in the tutoring arena. The platform does not only provide tutoring services but also helps with the completion of the assignment. The service providers offer students different options during the signing up process. There is a one-time option available that grants students tutoring over a period of time and a monthly subscription.

For students who require regular tutoring, the monthly subscription costs $40 per hour, $80 per two hours, and $115 per three hours.  If you would like a more flexible schedule, you can opt to pay $350 for 10 hours or $950 for 30 hours.

2.     Chegg

This is an excellent site for math tutoring services as the services are available 24 hours. The student is automatically matched with the suitable instructor after keying in the problems they have.  The user can opt for a live class, text, or audio.

For an off-chat lesson, the class costs $11 and $20 for unlimited chat lessons for a month. For those who would like a video call subscription, they will pay $30 for a month. You should also check out Math videos on YouTube to help you learn more and faster.

3.     Learn To Be

Free Exam Papers Secondary

Free Exam Papers Secondary 1, Secondary 2, Secondary 3 and Secondary 4

Secondary 1 , Sec 2 and Sec 3 papers are much harder to find as compared to Secondary 4 (O Level) exam papers, which can be found almost anywhere online. Even if you are willing to buy exam papers, you may not find any Secondary 1/2/3 papers for sale especially for rarer subjects like Chinese, History, Geography, English, etc.

Another type of exam papers that are very hard to find online are free Normal Academic (NA) exam papers. Most papers found online are Express exam papers, not Normal Academic. Normal Technical (NT) exam papers are even rarer.

On the other spectrum, free IP (Integrated Programme) exam papers are also hard to find online. Nonetheless, for most IP schools, the syllabus is not that different from Express (the order in which they teach the topics may be different). Hence, doing Express exam papers could also benefit students greatly.

There is a website named Smart Guppy which has free exam papers, and even personal notes compiled by top students from top schools like RGS. All notes and exam papers on Smart Guppy are free to every student, forever.

Free Exam Papers Secondary School

We have a list of Free Exam Papers on our Free Exam Papers main page. In addition, you may want to check out the site https://freetestpaper.com/, they have free exam papers from various secondary schools (login is required to download).

The websites mentioned above has exam papers such as:

  • Sec 1 Express Science SA2
  • Secondary 1 Express Maths
  • Secondary 1 Normal Academic Maths
  • Secondary 2 Express Science
  • Secondary 3 Express Chemistry
  • Secondary 3 Express Physics
  • Secondary 4 A Maths
  • Secondary 4 E Maths
  • and more free exam papers.

SG free exam papers

In general, you should always try to search for SG (Singapore) free exam papers before attempting to buy. Especially for Secondary 4 exam papers, they are the easiest to find and can be found easily by simple Googling. For other subjects, you may try to use some advanced Google tips and techniques in order to search for free exam papers.

Singapore exam papers are also widely favored by parents in Hongkong (HK), Philippines, Indonesia, and Malaysia. In Hongkong, Singapore Secondary Exam Papers are suitable for Junior Secondary 1 to 3 (Form 1 to 3) students. In Malaysia, our SG Secondary Exam Papers are suitable for students in Form 1 to Form 5 (ages 12 to 17).

Free Printable Exam Papers Singapore

As mentioned in our above paragraphs, you may wish to check out our main Free Exam Paper page, as well as sites like https://freetestpaper.com/. The exam papers are mostly in PDF format, and sometimes in Word Doc format, which are all printable. It is also common to print exam papers at a smaller size of 2 pages per sheet of paper in order to save paper.

Where to buy exam papers in Singapore

As a last resort, if you cannot find free exam papers, you may wish to visit Bras Basah Complex which is the traditional place to buy hard copy exam papers. There are also various sites online which sells exam papers, but only in soft copy.

Another place to buy authentic exam papers is through Carousell, where graduating students may sometimes sell their exam papers and notes since they have no use for it anyway.

For official O Level Cambridge exam papers, the place to buy them is at Popular bookstores, where they are often sold in the form of Ten Year Series. If you wish to find cheaper or older O Level exam papers, again the place to be is Bras Basah Complex, where there are many second hand bookstores selling such exam papers.

Neon Tetra Disease Treatment (Melafix)

Neon Tetra Disease is a mysterious disease that strikes mainly neon tetras, but other fishes are also susceptible to it. The online opinion is that there is no cure, some even suggest euthanizing the poor tetra to avoid it spreading.

Neon Tetra Disease Signs

The signs of neon tetra disease include some of the following classic symptoms:

  • Loss of color in a patch of skin
  • Fin rot
  • Curved spine in advanced cases

Our neon tetra exhibited two of the classic signs (white patch and loss of color near the head), and fin rot near the tail. For more pictures and graphics of the symptoms, see the video below.

Neon Tetra Disease Cure (Melafix?)

We seem to have stumbled upon a cure for neon tetra disease using Melafix. Melafix is a herbal fish medicine based on tea tree oil, and is targeted at bacterial infections of fish.

After one dose of Melafix, and over 9 days, our neon tetra has shown a dramatic improvement (as seen in video below). The white patch of loss of color is gone, and the fin rot near the tail is gone as well. In addition, the fin tissue near the tail has grown back to normal levels.


API Aquarium Pharmaceuticals 11J Melafix, 16 oz. (11J)

In the video below, our neon tetra was cured (after around 1 week) from Neon Tetra Disease, after dosing Melafix.

Neon Tetra Disease Cause

As mentioned before, there is almost no information on neon tetra disease, even though it is a very common disease of neon tetras. Some say that it is caused by a Microsporidian parasite called Pleistophora hyphessobryconis.

There is also a closely related disease called “False Neon Tetra Disease”, which is caused by bacteria. The symptoms are so close that it is impossible to tell apart the two diseases without a microscope in a laboratory.

According to famous fish keeper Cory from Aquarium Co-op, Neon Tetra Disease is caused by Mycobacterium, which also causes fish tuberculosis.

Neon Tetra Disease Cure

Based on our experience, Melafix certainly seemed to cure the Neon Tetra Disease. Then again, theoretically Melafix works against bacterial diseases but not parasitical diseases. Hence, it may work for the cases of Neon Tetra Disease which are caused by bacteria, but not for those that are caused by parasites.

Uncle Roger Data Scientist

Uncle Roger (real name Nigel Ng) is a very popular YouTube comedian, who shot to fame with his “egg fried rice” critique videos. Not many people know that Uncle Roger was actually a bona fide Data Scientist, who graduated from Northwestern University.

His classic viral video is the video critiquing BBC’s egg fried rice recipe. It has struck a chord with many Asians internationally, since the way BBC prepares egg fried rice is totally “wrong”, according to the traditional way fried rice is made in Asia.

Uncle Roger Rice Video

The below video is the classic original “egg fried rice” video that propelled Uncle Roger to stardom on YouTube. As of November 2020, this video has hit 18 million views, which is considered a lot on YouTube. Based on an estimate of USD$1-$5 CPM, this video alone has netted Uncle Roger USD$18,000 to $90,000.

As a continuation, Uncle Roger has also made various videos related to egg fried rice, for example the video featuring Gordon Ramsay.

Another popular video is the one featuring Jamie Oliver.

Nigel Ng (Uncle Roger) Data Scientist

What is not known by many is that Uncle Roger (aka Nigel Ng) used to be a data scientist, dubbed the “sexiest job of the 21st Century”.  Nigel Ng first studied at Chong Hwa Independent High School, Kuala Lumpur, and then moved to the US to pursue his studies at Northwestern University. He then relocated to London to work as a data scientist at various companies, before transitioning to comedy full time in 2019.

Uncle Roger (Nigel Ng) even has a GitHub page featuring the code he wrote: https://github.com/nigeljyng.  From his GitHub code, we can see that he works with Deep Learning using Keras.

Uncle Roger is actually quite young, his age is only 29 years old, and he is born on 15 March 1991.

Uncle Roger’s GitHub page, where he shares his data scientist code.

Uncle Roger Wife

Uncle Roger’s ex-wife is a fictional character named “Aunty Helen”. Not much is known about “Aunty Helen”, though there is a fan-made horror Halloween short movie featuring Aunty Helen.

Uncle Roger Fuiyoh and Haiya

Uncle Roger’s favorite slang is “Fuiyoh” and “Haiya”. “Fuiyoh” appears to be a Manglish (Malaysian English) slang word, spelled as “Fuyoh” on Wikipedia. It means exclamation of amazement / wonder / marvel, basically same meaning as “Wow!” or “Awesome!”.

“Haiya” also appears to be a Manglish (Malaysian English) word, spelled as “Aiya” on Wikipedia. It is a word to express surprise or dismay (more of dismay).

Uncle Roger Net Worth and Social Blade

According to Social Blade, Uncle Roger earns a whopping USD $77.5K – $1.2M based on his YouTube ad revenue alone. The range is huge due to fluctuations in YouTube CPM (cost per thousand views) based on region and other factors. But even the lower range USD $77.5k is a very high amount for a new channel like Uncle Roger (mrnigelng).

This shows that humor, or comedy, has timeless appeal. Even in the ancient times, or the futuristic era, laughter is always the best medicine.

Jinx Wild Rift Build

Jinx Wild Rift Guide

Jinx is the “mascot” of Wild Rift, which is the recent mobile version of League of Legends. Jinx is a worthy hero to play because of the following reasons:

  • Excellent ADC (Attack Damage Carry). Very high AOE and single damage output.
  • High Skill Cap. It actually requires a bit of skill to use Jinx, especially in terms of positioning and not dying. The art of switching between the two guns also requires skill.

League of Legends Jinx Wild Rift Build

The default build “AOE Marksman” for Jinx is actually quite good. The items you should get are:

  • Infinity Edge. The damage, and more importantly Crit, is especially important for Jinx. The increased 230% Crit damage scales even more under the attack bonus of Fishbones, the Rocket Launcher.
  • Runaan’s Hurricane. This item further increases Crit chance and Attack Speed, and strike 2 additional nearby enemies. This helps you to farm better in the initial stages, and deal massive AOE damage in the later stages.
  • Quicksilver Sash. This is important as Jinx is very fragile when under crowd-control effects. There is also some lifesteal worked into this item, which is helpful as in this build Jinx has no early game lifesteal.
  • Rapid Firecannon. Increases attack speed, crit chance further, as well as add even more range to Jinx.
  • Bloodthirster. Great for lifesteal and damage.
  • Last Whisper. Good for more armor penetration if there are many tanks in the game. Otherwise, you may wish to get Guardian Angel instead, for more survivability.

10 Kills, 0 Deaths, 3 Assists and MVP with Jinx in Wild Rift.

Jinx Wild Rift Role

Officially, Jinx is supposed to play as a Marksman (together with a support hero) in the Dragon lane (Duo lane).

If you are the only ranged hero, Jinx can also go in the Mid lane.

In a team fight, your role is to stand at the back, stay alive while dealing as much damage as possible with your guns.

Jinx Wild Rift Runes

The two preset rune builds for Jinx are quite good.

The default (Set 1) of runes are: Conqueror, Triumph, Loyalty and Sweet Tooth.

This set is good for maximizing damage (Conqueror can stack up to 30 Attack Damage, which is as good as half an Infinity Edge). Triumph also helps you to deal more damage to low health enemies to secure those kills.

The second default set of runes for Jinx are: Fleet Footwork, Gathering Storm, Spirit Walker, and Sweet Tooth.

Fleet footwork helps with mobility, and also the healing effect is good in the early game, especially in builds where Jinx does not have early lifesteal.

Gathering Storm builds up AD more and more, in preparation for the late game. The slow resistance for Spirit Walker is also great for a fragile hero like Jinx.

Jinx Wild Rift Skills

The way to learn Jinx’s skills is very easy to remember.

Just prioritize: Switcheroo>Zap>Flame Chompers, and learn your ultimate Super Mega Death Rocket whenever possible.

The most useful skill is surely Switcheroo. Zap is hard to hit, since it is blocked by any minions in front of the champion. Flame Chompers is only for your last resort escaping, or for punishing enemies who push too near to the turret (by throwing it behind them and prevent them from retreating).

Jinx Wild Rift Summoner spell

The meta seems to be to pick Heal and Flash. Basically, these two skills are the best to help Jinx escape and avoid dying.

My All 2020 Mathematics A to Z: Unitary Matrix

A great exposition (as always) of Unitary Matrices by Nebus Research Blog.

nebusresearch

I assume that last week I disappointed Mr Wu, of the Singapore Maths Tuition blog, last week when I passed on a topic he suggested to unintentionally rewrite a good enough essay. I hope to make it up this week with a piece of linear algebra.

Color cartoon illustration of a coati in a beret and neckerchief, holding up a director's megaphone and looking over the Hollywood hills. The megaphone has the symbols + x (division obelus) and = on it. The Hollywood sign is, instead, the letters MATHEMATICS. In the background are spotlights, with several of them crossing so as to make the letters A and Z; one leg of the spotlights has 'TO' in it, so the art reads out, subtly, 'Mathematics A to Z'.

Unitary Matrix.

A Unitary Matrix — note the article; there is not a singular the Unitary Matrix — starts with a matrix. This is an ordered collection of scalars. The scalars we call elements. I can’t think of a time I ever saw a matrix represented except as a rectangular grid of elements, or as a capital letter for the name…

Entering Good IP Schools is now Virtually Impossible for Students scoring below 65 for Chinese (MT)

Score less than 65 marks for Chinese (Mother Tongue), and it is Impossible to Enter Good IP Schools under the new system

This is a totally new era, where all previous PSLE strategies are outdated. Do share this article with your relatives/friends, where we show (using official evidence), that students scoring below 65 for Chinese (Mother Tongue) have virtually zero chance of entering good IP schools.

Since language (especially Mother Tongue) is the hardest subject to improve within a short period of time, students starting from as early as Primary 1 have to take note and adjust to the new PSLE scoring system. The Achilles heel for many students is actually Chinese language (or Mother Tongue), since it is very common for the entire family to be speaking English at home, at work, and with friends.

Our source of official evidence is the Straits Times, where it is indicated that the Official MOE Indicative AL COP range for 2019 PSLE for Express [Integrated Programme (IP)] is 6-9 points. For independent schools (which form the bulk of the best IP schools), the cut off point is 6-8. The same information can be found on Today Online, and Channel News Asia.

Indicative AL COP range for 2019 PSLE
Course Government and Government-aided schools Autonomous schools Independent schools
Express Integrated Programme (IP) 7–9 7–9 6–8
Achievement level (AL) Marks
1 90 and above
2 85-89
3 80-84
4 75-79
5 65-74
6 45-64
7 20-44
8 Below 20

Score under New PSLE System (for child weak in Mother Tongue)

Let us suppose the child scores:

  • >90 for English (AL 1)
  • >90 for Mathematics (AL 1)
  • >90 for Science (AL 1)
  • <65 for Chinese/ Mother Tongue (AL 6)

His/her total PSLE Score will be 1+1+1+6=9, which is not good enough to enter Independent IP Schools (requirement of 6-8 points). Independent IP Schools include schools like Raffles Institution, Nanyang Girls’ High School, RGS, HCI, and more. From common sense, the top IP schools’ COP is in fact likely to be on the lower end closer to 6 (or even lower?) rather than 8.

Score under Old PSLE System (for child weak in Mother Tongue)

Under the old PSLE system, the child’s score is likely good enough to enter even the best of IP schools:

  • >90 for English (e.g. 91)
  • >90 for Mathematics (e.g. 98)
  • >90 for Science (e.g. 95)
  • <65 for Chinese/ Mother Tongue (e.g. 64)

Estimated PSLE Score = (91+98+95+64)/4 x 3 = 261

The actual old PSLE T-score formula is slightly different (depends on bell curve and relative performance), but nevertheless, the estimated PSLE score of 261 is good enough to enter the best of IP schools like Raffles Girls’ School (RGS), RI, HCI. In fact, it is common knowledge that in the past, many students relatively weak in Chinese managed to enter RI and RGS due to their excellent scores in other subjects. Students in NYGH and HCI tend to have better grasp and mastery of the Chinese language.


A similar effect for students weak only in Math

The above effect is not unique to Chinese/ Mother Tongue. There are many students who excel in languages (English, Chinese), and Science, but are weak in Math for some reason or another.

The exact analysis also applies in this scenario, unfortunately. Basically, in order to enter top IP schools, no subject can be below 65 marks no matter how excellent the other subjects are.

Best Majors in Singapore

Update: To ensure that our list of best majors in Singapore is always updated, we have a poll below to reflect the updated views of readers. Do vote and check out the latest results!

Poll on the Best Major in Singapore:

Why is there a need to consider the Best Majors in Singapore?

There is an old Chinese proverb, saying that “The greatest fear of a man is to choose the wrong occupation.”. (男怕入错行,女怕嫁错郎.) Despite being thousands of years old, this proverb still holds true in the 21st century, even in advanced regions like the USA, Europe, and Singapore.

Basically, the choice of major directly or indirectly determines the future occupation or career path of a student.

Ancient Chinese Proverb:
“The greatest fear of man is getting into the wrong occupation. The greatest fear of woman is marrying the wrong man.”

(The first part still holds true, the second part may be outdated?)

男怕入错行,女怕嫁错郎

Best Majors in Singapore

There are many sources on the best majors in university or college, but focused on other countries such as the USA. Do take a look to see the general trend, but there are several majors that are “uniquely” good or bad in Singapore.

Best Majors in Singapore (Tier List)

Firstly, the best major in a sense is based on one’s interest and passion. For example, if one has totally zero interest in being a medical doctor or healing patients, it does not make sense going into the Medicine major in university. One may even burn out while attempting to do so.

That being said, if you have passion for multiple subjects, but have problem narrowing it down to a single major, it may be good to look at which one has the best prospects.

S Tier Majors in Singapore

  • Medicine
  • Dentistry

Based on the ageless theory of demand and supply, medicine and dentistry are bound to be the best for years to come. Demand-wise, humans are bound to get sick, and even more so with an aging population in Singapore. Supply-wise, the supply of doctors and dentists are strictly controlled by limiting the yearly cohort of medical students. In general, there will always be a shortage (or just enough), and never a surplus of doctors/dentists in Singapore.

The Singapore Medical Council (SMC) is a powerful organization, with the power to advice the Ministry of Health to cut overseas medical schools approved for practice in Singapore, for example. This helps to control the supply of doctors in Singapore.

Dentistry, though not as prestigious as medicine, actually have good earning potential as most visits to dentists are surgeries which cost more. From an official Youth.SG government website, the salary range is  $5,000 to $7,000 per month for fresh dentistry graduates.

In general, both medicine and dentistry are always among the highest paying degrees in Singapore. According to anecdotes online, there are people who are even willing to sell their house in order to send their child to medical school overseas (e.g. Australia); such is the attractiveness of the Medicine major in Singapore.

A Tier Majors in Singapore

  • Law
  • Computer Science (or other computer related majors)
  • Architecture
  • Pharmacy

Law is one of the highest paying degrees in Singapore, in fact potentially even more so than medicine. However, it is also known that being a lawyer is an extremely high stress occupation, and there is a high attrition rate because of that. In Singapore, 3 out of 4 (75%) local lawyers will leave practice within 10 years of commencing, according to the Law Society. That is why it is only placed at ‘A’ tier instead of ‘S’ tier.

For Computer Science, there is no need to explain, it is needed in all companies nowadays in the shift to high tech. Big data, data science, machine learning, is the hottest thing now. The only reason why computing science is only ‘A’ tier instead of ‘S’ tier is because there is no control on the supply of computer engineers/scientists in Singapore. Theoretically, it could happen that there can be more and more computer engineers/ data scientists trained (including from overseas) until the entire field is over-saturated. Also, from history, the technological sector tend to experience things like “AI winter” or “Dot-com bubble”.

Computer Science (and data science) is also recently one of the highest paying degrees in Singapore, with good job prospects. It is also quite compatible with the current “work from home” climate across the globe, it is unlikely to be disrupted by disease epidemics such as COVID-19 or future viruses.

For architecture, the pay is good and attracts top students. And also, even though Singapore is a small country with limited land, there always seems to be construction projects going on here and there all the time. For pharmacy, due to the laws, there is a constant demand for pharmacists required to dispense medication (for example every Guardian/Watson pharmacy needs one) and other duties. Hence, unless the laws regarding medicine change, there is always a constant demand for pharmacists.

B Tier Majors in Singapore

Note that “B Tier” still means good, while “A Tier” means very good!

  • Engineering (except computing)
  • Science (Physical science or hard science majors such as: Physics, Mathematics, Chemistry.)
  • Many others … (Vote in the poll!)

For engineering, this may be a surprise to foreign readers because in the USA, engineers are paid very well. According to the U.S. Bureau of Labor Statistics (BLS) engineers in America have a median annual wage of USD $91,010, which is  around SDG $122k.

In Singapore, engineering majors are “B” tier since they are still good in the sense that you could still most likely find a job related to what you study. Why they are not “A” tier is again due to the theory of demand and supply. The demand is not as high as say Computer Science, since Singapore is already slowly transitioning out of the manufacturing industry (e.g. do you see any big factories in Singapore?) For supply, again the number of engineers are not controlled, when there is a huge number of engineers (either trained or imported), wages will get suppressed.

For Science degrees (especially physical sciences like Physics, Chemistry, Mathematics), it is a solid “B” tier because the student actually learns useful and real quantitative skills that can be transferred to other domains. For example, it is very possible for physics or mathematics majors to transition to the finance industry after they graduate. Also, teaching in schools (public or private) is a valid option for Science majors.

Useless Degrees in Singapore

Many people actually search for “useless degrees in Singapore”, presumably to avoid them?

There is actually no such thing as a “useless degree”, since every degree from a recognized institution in Singapore does impart knowledge to the student. In the worst case scenario, they are still regarded as a general degree which will be recognized in the civil service or most major companies.

There is a notable mention to “Life Science” (Biology) degrees in Singapore though. Basically, the “Life Science” undergraduate degree in Singapore is widely regarded as not sufficient in itself to get a Life Science related job in Singapore, further degrees such as masters or PhD may most likely be required.

seriously it (Life Science Prospects in Singapore) is not good.

my batch people who went into life sciences are not doing well.

most have changed industries.

jobs are still few and not well paying.

i receive quite a lot of resumes from them, trying to do a mid career switch to engineering.

Source: Reddit

 

I was a life science grad specializing in biomed. Graduated in 2015

I would say out of my circle of friends, only one person went on to do research for a year for his masters. Everyone else went to do other things that were not life science related.

Source: Reddit

 

hi!! to be vv honest, life sci is q a bad place to be in rn (unless u are intending to do the duke-nus grad med track; which again, entry is vv competitive). i have friends who’re in life sci and they’re all desperate for phd bc degree really means nothing; they constantly joke about degree-holders being test-tube washers lmao. in nus faculty of sci, the dean’s list is often filled w ppl from life sci whose CAP are v high. that’s bc life sci mods are generally easier than other sci courses, and the cohort is bigger (so more bellcurve tankers). and when a degree is relatively easy, u can imagine it’s prospects

Source: Reddit

An excellent world-class post on why the Life Science / biology hype died down worldwide, not just in Singapore:

It died down worldwide imo. There was a lot of hype about genetics and biotech in the 90’s, but after the Human Genome Project was completed in the early 00’s everyone realised that there are several more levels between genes and phenotype, e.g. epigenetics, mRNA regulation, proteomics, nutrition, lifestyle choices, pathogens, behaviour… And we can’t even be certain that there aren’t more levels which we are currently unable to perceive.

Despite the predictions of futurists in the 90’s, we still can’t fully explain the pathways that lead to cancer or Alzheimer’s or heart disease, let alone fully formulate rational treatments for them. And forget about designing artificial life from scratch.

There was a mountain that science hoped El Dorado lay hidden behind, but after climbing it science found only a bit of gold, and 5 higher mountains in front. It’s just the way the universe is really; nobody could have known that the 5 mountains existed before climbing the first.

Guardian Promotion Singapore (40% Discount)

Click on the link to enter the Guardian website, where there is up to 40% discount off selected items!

Official URL for Guardian website: Guardian.com.sg

There are quite a lot of good deals on the Guardian website, that may not be found in Guardian physical stores. The reason is due to the limitations in size of Guardian physical stores, they can’t carry all possible products whereas the Guardian website can.

For example, some of the promotions that are ongoing now are:

  • Up to 40% off vitamins and supplements
  • Buy 1 get 1 free for Facial Masks and Cleansers
  • 20% off selected Skincare products
  • 2 For Deals, up to 400 products
  • Free Portable Juice Blender, with $100 spent on health products

Guardian Promo Code

I don’t think Guardian has a Promo Code, and even if there is, I don’t think the Promo Code can stack with the online discounts from the Guardian website.

Guardian Passion Card

The member card for Guardian is the PAssion card, similar for Giant supermarkets. Other cards that are beneficial at Guardian include the “UOB One Credit Card“, and “Golden Senior Card“, which is for adults aged 50 and above.

When You Speak They March: Alumni Network Rules of Engagement

When You Speak They March: Alumni Network Rules of Engagement

Like schools, universities and other institutions, alumni play a pivotal role in the success of non-profits and foundations.

Organizations quickly realize the potential of keeping past participants connected and aware of institutional activities. In that context, these bodies need rules of engagement, modes of engagement, and ways of measuring impact.

Provide practical value in alumni engagement

Alumni are defined within the premises of shared identity or experience. But these factors may not be enough to keep your members engaged forever after the event or outreach is done. Consider creating practical value for members in exchange for continued association with the alumni.

Modern-day alumni expect a unique, balanced value proposition when they share their time, donations, skills, and attention. You can meet them halfway with support platforms for networking, referrals, or skills development.

The derived value from the engagement will strengthen the shared identity and fuel the desire for continued fellowship in the long run.

Implement real-time engagement

The desire to be part of and participate in your nonprofit’s activities can quickly wane in the face of limited interaction. Value creation is not a solve-it-all solution. For communities to realize the benefits of alumni network, modes of engagement must be set and optimized.

Traditional alumni interactions rely on face to face meetings. These have the advantage of the personal touch but many limitations in time and space.

With the growth of digital technologies, virtual alumni interactions have proven effective in driving more connections and opportunities for members.

In the age of social distancing, adopting a virtual alumni engagement platform is the wisest thing to do to keep the connection going.

The right alumni engagement digital platform should save your time and boost your impact. In the traditional sense, managing and communicating with all members can be hectic and time-consuming.

A dedicated digital platform makes it possible to harmonize data, personalize messages, and keep the conversation going so that you don’t find yourself without donors in your next campaign.

Provide tangible results and impact assessment

Motivated and goal-oriented alumni networks will have a shared desire to assess their achievements. Without the data or accurate data, you risk snuffing out their passion for making positive change.

The best non-profits find ways to quantify results by establishing metrics for measuring outcomes throughout an outreach.

Historically, quantifying results has been difficult for many nonprofits. Many therefore resort to reporting inputs as outputs like the number of new volunteers or awards won. For sustained donor engagement and participation, you will need data on real, measurable outcomes.

Embrace data and relevance

The right digital platform can help you analyze impact against your set metrics. That way, you can confidently show your constituents what their time and money are achieving regarding your cause. Attaining that accurate reporting requires optimal data harvesting and analysis.

The right data can further help to keep engagement relevant. As your network grows, generalized messaging might cease to be effective.

You will probably need a segmentation algorithm in your communication to keep the engagement personal, relevant, and meaningful to the individual.

The best alumni engagement platform helps you reach and retain constituents through strong and personalized messaging.

You can seamlessly and expediently gather ideas from each member to make them feel involved. You can break down data and find out which supporters need a higher level of engagement.

It is impossible to sustain alumni networks without technology by your side. The best virtual alumni platform makes your connections easy and impactful.

This blog post summarizes all the information on Amos Yee Education, as well as honors and awards. All the education information are/were publicly available on the internet, but scattered across various sources.

Amos Yee achieved good academic achievements, but later got into a great deal of trouble, including jail time in both Singapore and America.

Amos Yee Education (Primary School)

  • 2005 – 2010: Pei Chun Public School.
  • Scored 244 for PSLE, with A* for Mathematics and Science, and A for English and Chinese.

How to keep floating plants in aquarium

Floating plants are a great addition to the home aquarium. The first few times we tried to keep floating plants, it all failed. Water lettuce, frogbit, and red root floater all melted away and died within days.

After multiple tries, we think that we have figured out the tricks to keep floating plants in the aquarium! The YouTube video below summarizes 8 essential tips for keeping floating plants alive and thriving in the home aquarium.

For beginners we recommend Salvinia, or water spangles, as the first starting floating plant. It is also easy to remove, as a great contrast to duckweed.


NA2 Live Water Spangles, Salvinia Minima, Water Velvet, Free Feeding Ring Aquatic Plant Aquarium Fish Tank, Top Water Plant, Floating Pond Plant, Pond, Goldfish, koi (24+ Spangles)

There are many advantages of Salvinia, including it being one of the easiest floating plants to keep alive.

Python matplotlib Plot Multiple Figures in Separate Windows

Matplotlib is a popular plotting package used in Python. There are some things to note for plotting multiple figures, in separate windows.

A wrong approach may lead to matplotlib showing a black screen, or plotting two figures superimposed on each other, which may not be the desired outcome.

Sample Matplotlib Code for Plotting Multiple Figures in Separate Windows

import matplotlib.pyplot as plt

plt.figure()
# plotting function here, e.g. plt.hist()
plt.savefig('filename1')


plt.figure()
# plotting function here, e.g. plt.hist()
plt.savefig('filename2')

plt.show()

One way to do this is to use the plt.figure() command for each figure that you want to plot separately. Optionally, you can use plt.savefig() if you wish to save the figure plotted to the working directory folder.

At the end, use the plt.show() command. The plt.show() command should only be used once per script.

GIGANTIQ Reviews

GIGANTIQ (sometimes spelled as “Gigantic” by users) is an insurance savings plan, similar to Singlife or Dash EasyEarn. As of the current date, Gigantiq (purchased through PolicyPal) is clearly superior to Singlife or Dash EasyEarn, with 2% p.a. interest and up to 8% PolicyPal bonus credits earnings.

Gigantiq (Gigantic) vs Singlife

Singlife has recently reduced their interest rate to 2% (down from 2.5%). Hence, GIGANTIQ has the benefit of the additional 8% PolicyPal bonus credits compared to Singlife. The PolicyPal bonus credits are quite useful, it can be converted to NTUC FairPrice vouchers, Grab vouchers, or even cash.

Gigantiq (Gigantic) vs Dash EasyEarn

Dash EasyEarn has reduced their interest rate to 1.8% (down from 2%). Hence, GIGANTIQ is the clear winner here.

Please use our GIGANTIQ Referral Code MATH88 when purchasing the plan via PolicyPal. It is very important to purchase through PolicyPal for the following reason:

  • Earn up to 8% p.a. in PolicyPal bonus credits, which can be exchanged for grocery vouchers, Grab rides, or even cash. If you buy GIGANTIQ from other sources, there is no such bonus.

Gigantic Etiqa (Gigantiq by Etiqa)

The Gigantiq policy is underwritten by Etiqa Insurance Pte. Ltd, which is the insurance branch of the Malaysian banking group Maybank. Maybank is the largest and most valuable bank in Malaysia.

Gigan tiq by Etiqa review (Pros and Cons)

  • Etiqa is the insurance branch of Maybank, which is the largest bank in Malaysia.
  • 2% p.a. returns for first S$10,000 for the first year.
  • No lock-in period. Withdraw and top up anytime.

  • Protected under the Policy Owners’ Protection Scheme which is administered by the Singapore Deposit Insurance Corporation (SDIC).

Gigantic (Gigantiq) vs Elastiq

Currently, there is not much point comparing Gigantiq with Elastiq, since ELASTIQ is fully subscribed. That means, you cannot open an ELASTIQ account even if you want to, it is totally full. In any case, the interest rate of Elastiq is 1.80% p.a, which is lower than Gigantiq.

Hence, do check out GIGANTIQ, Etiqa’s all-in-one insurance savings tool before it’s gone too!

Gigantiq Forum

As a final note, you may want to read the reviews of Gigantiq on a popular forum, Hardwarezone. Most of the reviews there are positive, and most recommend putting in $10,000. Any amount above S$10,000 has a reduced interest rate of 1% p.a.

Previously, we have written on Singlife Review before, just to update and give more details on the excellent Singlife 2.5% interest account and give an in-depth review.

Basically, Singlife’s 2.5% interest is the highest among all deposit accounts in Singapore as of September 2020. (If you know of any higher interest rate accounts, do comment below!)

Also, Singlife’s 2.5% interest does not require you to do any credit card spendings, nor do you need to credit your salary, nor purchase any insurance or investments (unlike DBS Multiplier or OCBC 360 account). Basically, you need to do nothing!

If you put in $10,000 into Singlife (which is the recommended amount to put in), it is a free $250 for you within one year. For amounts greater than $10,000, it is recommended that you put the rest into Dash EasyEarn.

In conclusion, due to reduction of interest rates in banks, currently there is no bank account (be it savings or even fixed deposit) that can beat or even come close to Singlife’s 2.5% interest. (Unless you can fulfill multiple conditions in DBS Multiplier.)

Hence, Singlife’s 2.5% interest rate is very attractive currently!

We recommend and review some laptops/notebooks suitable for data science and machine learning.

Firstly, we state the 4 core important specs (specifications) for laptops for data science and machine learning.

1) RAM: Should be 8GB or higher.

2) CPU: Should be Intel Core i5, or even better Intel Core i7.

3) Storage: Should be at least 256 GB SSD.

4) GPU: Optional, but good to have for deep learning. (Note that Mac GPUs are not usable for deep learning.)

RAM and CPU are necessary in order to conduct computations successfully and within a reasonable time. Storage is necessary to process big data which can potentially be several gigabytes. GPU is useful to speed up deep learning, but is optional since there are many cloud or server options available.

For concrete recommendations, we recommend the following 5 laptops. Certainly, there could be other laptops that are equally suitable for data science and machine learning, do comment below if you have a good suggestion!
