Hikari Shrimp Cuisine Review

I find this Hikari Shrimp Cuisine quite good. The pellets are quite small sized so you can control exactly how much you want to feed (down to each individual pellet).

How to feed Hikari Shrimp Cuisine Pellet (without fish snatching it away)

This was something that perplexed me for a long time. My fish would grab any food meant for the shrimp, leaving close to nothing left for the slower moving shrimp.

The solution I found was to:

1. Put the Hikari Shrimp Cuisine pellets in a small container with tank water.
2. Crush the pellets (I just use my finger).
3. Stir to “dissolve” the pellets a little. Stirring also helps the pellets to sink.
4. Pour the water with “dissolved” pellets back into the tank.

You may switch the order of steps 1 & 2 if you like (I find it easier to crush the pellets when wet).

The main reason why this works is because:

• Hikari Shrimp pellets are sinking (this is very important since shrimp can only eat sinking pellets that reach the floor).
• By crushing the pellets into powder, it is virtually impossible for the fish to snatch all the shrimp’s food.
• Some, if not most, of the powder will reach the tank floor, where the shrimp can find and eat it.

Another way to feed shrimp exclusively is the usage of a shrimp feeding tube and feeding dish.

How much Hikari Shrimp Cuisine Pellets to feed

This depends on how many shrimp you have, and also your tank setup. Ideally, shrimp such as cherry shrimp or Amano shrimp can survive on algae and biofilm. Hence, if your tank is well planted, you only need to feed lightly. Personally, I only feed the shrimps once a week, at around 2 Hikari Shrimp pellets per shrimp.

If your tank is bare (no plants), you need to feed more, maybe once every day or once every two days.

Supplementing with Hikari Shrimp food is good because it contains essential minerals like copper (shrimp need small amounts of copper) and other minerals that can help shrimp molt.

Toy Poodle Male Temperament

Just adopted a toy poodle (male). It is supposedly the 2nd most intelligent dog (after the Border Collie).

I was quite surprised that it is quite a well-behaved small dog, that seldom barks. It is currently 3 months, and only weighs around 1.5 kg.

Male vs female toy poodle temperament

Apparently, for poodles, it can often be the males that are more affectionate and loving and the females that are more dominant and challenging of authority. (Source: https://poodlereport.com/male-vs-female-poodles-what-are-the-differences/)

Another poodle website source claims that “males tend to be more affectionate, playful, easier to house break and train, attentive and more demanding of attention. They adore their people and want to please. Most importantly if you have more than one person in your family, male dogs love everyone equally and share their affection with everyone. Female dogs tend to be a one person dog.”

Ideal in Ring

Historical Background:

Ideal (理想) was a by-product by mathematicians in the 350-year proof of the 17CE Fermat’s Last Theorem, wherein they found a violation of the existing “Fundemental Law of Arithmetic” (Unique Prime Factorization) . Since it is a Law, there must be an alternative ideal number to satisfy it, hence the birth of the “Ideal”.

Read here: the raison d’être of Ideal : What is an Ideal ?

Note:

Why Integer (Z) is called “Ring” (Dedekind coined it using the German word “Der Ring”) ? because
{1, 2, … , 11, 12 = 0} is clock number “Z/12Z” like a Ring-shaped Clock 🕜

Application:

The ancient “Chinese Remainder Theorem” (aka 韩信点兵 ) since 200 BCE is explained by 19CE Ideal Theory.

Stickers Math Question

Abby, Brian, Charles, Dennis and Eason have 50 stickers altogether.

Abby has the most stickers — she has 12 stickers.

In second place (tied) are Brian and Charles.

In third place is Dennis.

In fourth place is Eason, with 6 stickers.

How many stickers does Dennis have?

This is part of a series on Homeschool Math Challenging Puzzles, suitable for Grades 2-4. (Of course, students of other grades are also welcome to try them out.) The questions are suitable for:

• Preparation for GEP (Gifted Education Programme) screening and selection tests
• Puzzles for kids interested in math but find school work too easy.

For this type of questions, the easiest way to do is “trial and error”, also known as “guess and check”.

Firstly, lets check how many stickers B, C, and D have together:

50-12-6=32

 B C D Total (B+C+D) Comments 9 9 14 32 Wrong! Since D is more than A 10 10 12 32 Wrong! Since D is tied with A 11 11 10 32 Correct! 12 12 8 32 Wrong! Since B, C is tied with A

For guess and check, the most important thing is to be systematic, rather than guess wildly. For instance, we can systematically increase our guesses for B, C.

We can see that the only logical answer is:

B= C=11

D=10

What are some best hacks to switch careers?

Just saw this post on Quora. Reblogging it here in case the original post gets deleted.

Quite interesting advice, with a nice name of “monkey bar technique”.

My PhD advisor once gave me the advice to use the “monkey bar technique”.

If you have achieved success in field X, and want to move into field Y, then you really don’t want to have to go back down to the bottom again and have to work your way up. Instead, a better approach is often to use your skills in field X to get a job that allows you to build expertise in field Y.

Sometimes you might need to take several steps to get where you want, where in each step you use your current skills to get a job that allows you to build new skills. This is similar to the way a child moving across the monkey bars holds onto one bar while reaching out for the next one.

In my case, I started out with a PhD in programming language implementation, which led to a job as a research scientist at Intel where I learned about the web, which led to a job as a software engineer at Google where I learned about product design, which led to a job as a product manager at Google and then Quora.

Chai Discus Shop Tour by Ryo Watanabe

This Japanese boy Ryo Watanabe is currently based in Japan, but used to be in Singapore for some time (his mother works here). I think he is probably back in Singapore recently again based on his videos.

Very amazing discus fish store tour. I usually enjoy watching his videos during meals, I think I have watched almost every single video (except those super long video interviews which may be more than an hour).

Do subscribe to his channel, and like, share, etc. His videos are usually very professionally produced, and he speaks very good English. Sometimes, I wish I have the time to tour all the fish stores like him.

SG Bearded Aquarist Fish Videos

Another fish YouTuber based in SG is SG Bearded Aquarist. Currently, he seems to be “inactive” for quite some time, maybe working on a new project? His videos are also very professionally produced, and he does branch out to overseas aquariums/ saltwater/ planted tanks as well.

One of my favorite videos from SG Bearded Aquarist is the one below (featuring Zaric and Jarenn Foo who are expert Pleco breeders).

This is something quite interesting. Possibly a very good idea for many bloggers — kill two birds with one stone (write a book while developing a blog).

We know many of you love your blogs, and gleefully publish photos and posts without thoughts to reuse your work in other forms. But we know some wonder: could this be a book? Recently we wrote about how a WordPress.com blogger scored a book deal for You Are Not So Smart. But what if you want to do it all yourself?

As a blogger who has authored several successful books with publishers, and who works on WordPress.com, I recently self-published a book based entirely on posts from my blog. I wanted to see what I could learn, and I’m here to share it all with you.

The book I self-published is called Mindfire: Big Ideas for Curious Minds. It’s a collection of my best essays from my WordPress blog at scottberkun.com, where I write about ideas, creativity and leadership. The book has done well, and has often been in the top 100 books on philosophy and other categories on amazon since it was published.

There are four questions I often get asked by other bloggers.

This is the wrong way to start. A book is a different reading experience than a blog, and to “shape” a blog into a book assumes words are like clay, where you can shove them into any shape you like. A book is a longer reading experience, and every chapter, or every page, needs to line up in a readable way with the others. It will take some effort to rework  material written for a blog to fit well together as a book. Don’t start with the assumption you’ll include every single post on your blog, or keep them in the chronological order they were written.

The first step is to make two lists: possible posts and possible concepts. You might discover a book concept that’s strong, but you only have 10 or 12 posts that fit. That’s ok. You can always choose to write more. Of course the theme of your entire blog could be the theme for a book, but consider other concepts too.

I went back to the beginning and made a list of posts that might be good enough to include. I made a separate list of possible book concepts. One concept I saw in some of my posts was intelligent provocation: asking big questions and offering intelligent and entertaining answers. I filtered the list based on that concept, and arrived at 45 possible posts.  Then I hired an editor to help refine the list, and the result was 30 posts that, while all written independently, fit together into an excellent read.

There are services like Blurb or Blog2print that will take your WordPress.com blog and build a book from it. If your WordPress blog is self-hosted, and not on WordPress.com, you might take a look at Anthologize, a plugin that automates the process of converting your blog into an e-book. But these services do nothing to shape your work into a great read. No software can do this for you.  There is an enormous distance between a ‘book’ and a ‘book someone will enjoy reading’ and that distance is closed only by your hard work.

Plan to take a draft version of your book and ask people to read it. Ask for feedback on improving the order of posts, or which posts don’t fit. You’ll notice people expect tighter and more careful writing in a book, compared to reading posts online. It’s acting on this feedback that makes the difference between a book that feels like a book, and a book that feels like a bunch of random posts thrown together. Revise posts, or write new material, to develop the book into a singular strong narrative. I asked for volunteers on my blog for people to give feedback on the drafts and their input was a key part of making the book so strong.

2. How do you actually (self) publish a book?

To go the traditional route, you’ll need to reach out to publishers or agents and try to find one that’s interested. This takes significant effort beyond writing the book itself. In all cases, traditional or self-published, the hardest part is writing and editing an excellent book. If you’re dedicated to your book, self-publishing can allow you to focus your energy on making the book better, rather than in searching for someone to give you a chance you can give yourself.

If you already have a well edited manuscript, you are most of the way there: the technical parts of self-publishing are surprisingly easy. You take your complete manuscript, after it has been copyedited and reviewed by an editor, and convert it to a PDF. With a PDF in hand, there are many services that will convert your PDF to a print or digital book for you.

For Mindfire, I used Lightning Source for the print edition, and a service called BookBaby to manage the digital editions.  These services list the book on amazon.com, and it can be purchased like any other book on amazon.com, including KindleiBook and other digital versions. It doesn’t cost much: maybe a few hundred dollars. If you choose to only produce a digital version, it can be much cheaper.

The more work you do, the cheaper the services are. If you are willing to hire your own editor and cover designer, or do those tasks yourself, and take care of details like getting an ISBN number, you can user services like  Lightning Source or CreateSpace to simply print and distribute he book. But if you want to hire people to help you, services like CreateSpace and Lulu.com let you pay them to take care of many steps on your behalf.

3. Why would people buy a book if the content is free on the blog?

The rise of the iPad and Kindle have proven the demand for longer reading experiences, experiences longer than what the web provides. A compilation of your work offers a deeper experience than what people get through your blog alone. Blogs are fantastic for small to medium length reading experiences, but to consume 40 or 50 posts without interruption, posts that are chosen to fit together on a specific theme, you need something else. A book is a better experience for this kind of continuous reading.

4. How can I use my blog to help the book succeed with the book?

If you involve your readers as your produce the book, they will naturally help spread word when it’s done. Using polls I asked my readers to help pick the title, to give feedback on several rounds of cover designs, and many other decisions. This attracted new readers curious about how books are made, and allowed me to collaborate with my readers on the book, increasing their interest in seeing it finished and released.

It’s counterintuitive, but giving the book away for free for a time helps a new book, and your blog, tremendously.

5. What’s the first step to take?

You’re a blogger: start by blogging about it. Ask your readers if they’re interested in helping you work on a book. Post your list of book concepts and see what they think. Perhaps there’s an author, editor or designer who reads your work that can lend their expertise. Take a careful look at the work you’ve already written and start thinking about what concepts might match.

Marbles Math Question

Aaron and Bob had some marbles in a box.

At first, Bob had thrice as many marbles as Aaron.

Aaron sold 5 marbles and Bob bought another 35 marbles.

Then, Bob had 5 times as many marbles as Aaron.

How many marbles were there in the box at first?

This is part of a series on Homeschool Math Challenging Puzzles, suitable for Grades 2-4. (Of course, students of other grades are also welcome to try them out.) The questions are suitable for:

• Preparation for GEP (Gifted Education Programme) screening and selection tests
• Puzzles for kids interested in math but find school work too easy.

Solution:

This question can be solved using the “units” method, and “working backwards”.

At the end, Bob had 5 times as many marbles as Aaron.

We write:

Aaron –> 1u

Bob –> 5u

Next, we work one step backwards (before Aaron sold 5 marbles and Bob bought another 35 marbles.)

Aaron –> 1u + 5

Bob —> 5u – 35

Now, we calculate what is 3 times of Aaron (thrice of Aaron’s marbles):

3 times of Aaron –> 3u + 15

We can conclude that:

3u+15 = 5u-35

We may draw the above model, after which we can conclude that:

2u –> 15+35=50

1u —> 25

Hence, Aaron had 1u+5 = 30 marbles at the start.

Bob had 5u-35 = 90 marbles at the start.

In total, there are 30+90= 120 marbles at first.

Ans: 120

7 Essential Abilities To Be A Successful Entrepreneur

7 Essential Abilities To Be A Successful Entrepreneur

Destination wanted by anyone who opens their particular company is a success.  However, despite the same objective, entrepreneurs can achieve success by taking very different paths. Regardless of the differences. Some values are typical of the huge majority of successful entrepreneurs. However, different from the profile of everyone is. Several training courses such as HR training courses, personal development courses, administration courses etc are conducted by Zoe Talent Solution. These courses help you to increase the growth of the business and helps to run the business successfully.

1. Ambition

Without the desire to grow, achievement becomes more difficult.  To be ambitious is to have courage, firmness, and accept challenges, which means leaving your comfort zone.  Many views, that this value as something negative, possibly because they imagine that ambitious individual may harm others to reach their objectives, which isn’t correct. There’s absolutely no such lack of scruple.  What there is is an excellent instinct for competitiveness and a willingness to lead.

1. Control

Achieving success isn’t straightforward.  Until everything goes well, lots of people get into debt, it takes time to construct a fantastic team and suffers to entice customers, among some other issues.  And, it isn’t easy to go through bad times without psychological control to withstand that pressure. The entrepreneurs must be willing to take risks.  If you want a more predictable life, maybe owning a business isn’t the best means for you.

1. Perseverance

Another important element that stands out in many lists of essential ingredients in the entrepreneur’s profile is perseverance.  Without that determination, you give up at the first sign of crisis.  So it’s important to believe that however long it takes you’ll get along.

1. Be sociable.

Whoever has their own business should relate, at all times, with clients, employees, and suppliers.  Therefore, extroverts have a certain advantage.  However, this doesn’t necessarily mean that shy people don’t stand a chance when undertaking.  They simply have to surround themselves with people that are good at interpersonal relationships.

1. Being a revolutionary is not compulsory

We often associate the image of the entrepreneur with that of the inventor that transforms a brilliant idea into a unique and disruptive business.  But, according to Santos, the entrepreneur isn’t always an inventor.  They could do very well when perfecting a product, or improve the processes of creating something.

1. Relationship Building

Building relationships in business are essential for entrepreneurs because powerful relationships are required to resist persistent anxieties.  Relationships with colleagues, suppliers, clients, investors and a high number of different stakeholders are important. Great relationships that are maintained over time demand a whole lot of work and a great deal of skill.  Having a fantastic relationship focuses on trust, and if it is possible to create a sense of confidence in yourself and your business, this is going to be quite helpful. Concentrate on creating situations where everyone wins and ask yourself how I can improve things for another person is a handy way to build relationships and trust.

1. Continuous self-development

Those working in large companies are frequently asked to take part in the training.  Ideally, when you tackle, you continue to”train” your mind.  We are living in a world where everything changes very quickly and you will need to be always current.

Going Hungry In Singapore

Singapore is famous for its cheap hawker food, including the cheapest Michelin-starred meal in the world. Why does hunger, or food insecurity, still exist in this city?

Food insecurity refers to the lack of reliable access to nutritious food due to financial constraints. But we found that it doesn’t exist only among the lower-income or the elderly poor. In a two-part special, CNA Insider investigates the issue of hunger, and the efforts to address it in Singapore. We spent months talking to recipients of food aid, and groups like The Food Bank Singapore, Free Food From All, Food From The Heart, Keeping Hope Alive, Willing Hearts, Volunteer Switchboard and SG Food Rescue.

GEP Test Format

There is limited information on the GEP Test Format on the official MOE website:

IDENTIFICATION OF PUPILS FOR THE GEP

The entry point into the GEP is at Primary 4.

Pupils are identified for the GEP through a two-stage exercise in Primary 3.

Stage Month Participants Papers
Screening August Primary 3 pupils enrolled in government and government-aided schools English Language

Mathematics

Selection October Only shortlisted pupils will be invited to the Selection stage English Language

Mathematics

General Ability

For the screening test, the duration for each paper is around 1.5 hours.

For the selection test, there are traditionally two papers of 2.5 hours each:

• Paper 1: English paper and a General Ability paper
• Paper 2: Maths paper and another General Ability paper

In August every year, the cohort of P3 students is invited to sit for a GEP screening test. The test is not compulsory but all children are encouraged to go for it. The test comprises an English and a Maths paper, about 1½ hours each.

Out of the cohort of approximately 50,000 kids, some 3,000 pupils (about 6%) are shortlisted for the GEP selection test.

The selection test takes place over two days in October, the first comprises an English paper and a General Ability paper, about 2½ hours in total. The second consists of a Maths paper and another General Ability paper, also about 2½ hours altogether.

GEP Test Syllabus

Officially, the GEP Test can only test within the Primary 3 syllabus. (This is more relevant for Math than English. For English, it is more open-ended, they can test advanced GEP vocabulary like “cantankerous”.)

For example, technically they are not supposed to test “speed” questions since that is a Primary 5 topic. Similarly, they are not supposed to test area/perimeter of circle questions, or even area/perimeter of triangle questions.

Hence, the GEP Math Test Syllabus (according to the official Primary 3 syllabus) includes:

1. Whole Numbers
2. Fractions
3. Money
4. Measurement (Length, Mass, Volume)
5. Time
6. Area and Perimeter (rectangle/square)
7. Angles (basic concepts of right angle, acute angle)
8. Perpendicular & Parallel Lines (basic concepts)
9. Bar graphs

The above topics may seem deceptively easy. However, even for a simple topic like fractions, it is possible to test a question like the GEP Screening Test Question Sample: The Tap Question, which may stump many secondary school students.

Mosquito Rasbora & Neon Tetra

Mosquito Rasbora (Boraras Merah / Phoenix Rasbora) can live peacefully together with neon tetras!

The neon tetras mostly ignore the smaller mosquito rasboras, except maybe during feeding time where they try to snatch the food. There has been zero aggression between the mosquito rasboras and the neon tetras.

Mosquito Rasbora are surprisingly clever and have distinct personalities. One of my mosquito rasbora prefer to hangout near the top of the water together with the neon tetras, while another prefers to swim low near the roots of plants.

Should I fast my fish once a week?

Many aquarium hobbyists propose fasting their fish once a week (i.e. not feeding the fish one day every week). The benefits of doing so include:

• lower chance of constipation / bloating which may lead to swim bladder disease
• clear the digestive system
• better water quality (this is not the main point, but a side benefit)

I think in part people fast fish because in nature, if the fish was living it’s natural life, it would never be able to count on finding food every day, so fasting now and then is seen to be more in keeping with a natural life. Living in a glass box is so far from nature I’m not sure how valid that reasoning is, but it does no harm.

Man made foods are also filled with things the fish would never, ever eat in the wild, so fasting may be a break from some of that. Might be better to alternate man made with frozen or live though, the fish will be healthier for it.

If a fish has been constipated, fasting may well give the bowel a needed rest. Man made foods have many things like flour and other binding or bulking agents, and they are, I think, one of the prime reasons some fish become constipated. It’s not what they evolved to eat.

Just for an example, feeding living daphnia in quantity to fish is almost like giving them a laxative, they shoot through so fast, but fish eating living daphnia have amazing colour and vitality too. Great for conditioning to breed. In the wild daphnia are rather ephemeral, having huge numbers in spring and far fewer later. So fish and other critters that eat them, eat them much like we do some of the more perishable fruits.. when they’re available ! They eat all they can ’til they’re gone.

There is also a scientific research article on fasting tilapia fish. Basically the study found that “Overall, results suggest that fasting one day a week does not affect growth efficiency and that tilapia adjust well to relative changes in feeding frequency.”

What is 8 ÷ 2(2+2) = ?

The correct answer, according to New York Times, is 16!

The other popular answer is 1.

The main idea is to use the BODMAS rule, to evaluate the bracket first. Then, it becomes 8÷2×4 = 4×4 = 16.

Jeff Bezos: How do you say no to annoying meeting requests?

How do you respond:

1. A) Yes, I’ll definitely meet with you.
2. B) No, I won’t meet with you.
3. C) Tell you what. Call so and so and they’ll work something out.
4. D) Quietly resolve to become a shut-in.
5. E) Something else (fill in the blank)

Quite interesting to see Jeff Bezos’s answer (Option C).

Unfortunately this option only works for higher level executives who have a secretary/admin staff?

Python (Anaconda) does not work with MacOS Catalina!

This is just to highlight that the Anaconda Python Distribution does not work with the latest MacOS Catalina. I only realized upon trying to open Anaconda Navigator, after installing Catalina.

The only (good) solution seems to be reinstalling Anaconda.

MacOS Catalina was released on October 7, 2019, and has been causing quite a stir for Anaconda users.  Apple has decided that Anaconda’s default install location in the root folder is not allowed. It moves that folder into a folder on your desktop called “Relocated Items,” in the Security folder. If you’ve used the .pkg installer for Anaconda, this probably broke your Anaconda installation.  Many users discuss the breakage at https://github.com/ContinuumIO/anaconda-issues/issues/10998.

LaTex Plot Axis 3D

There are many packages in LaTeX to plot 3D, including tikz-3dplot, and other exotic packages.

The easiest one to use for plotting a simple 3D graph, with xyz axis and origin, is Pgfplots in my opinion.

The code to plot the diagram below is included for reference.

First, we need to add the following in the preamble of the LaTeX document:

\usepackage{pgfplots}
\pgfplotsset{compat=1.8}

Then, to draw the actual diagram, the following simple code will do:

\begin{figure}[htbp]
\begin{center}
\begin{tikzpicture}
\begin{axis}[
ticks=none,
view={60}{30},
axis lines=center,
width=10cm,height=10cm,
xmin=-10,xmax=10,ymin=-10,ymax=10,zmin=-10,zmax=10,
xlabel={$x$},ylabel={$y$},zlabel={$z$}
]

% plot dots for the points
\addplot3 [only marks] coordinates {(1,2,3) (4,5,6)};

% plot dashed lines to axes
\addplot3 [no marks,densely dashed] coordinates {(1,2,3) (4,5,6)};

% label points
\node [above] at (axis cs:1,2,3) {$A (1,2,3)$};

Neon Tetra Bloated (Constipation)

One of my neon tetras is bloated/constipated. It has trouble sinking, it is swimming heads down and tails up. Hopefully it does not progress to the dreaded swim bladder disease or dropsy. Possible reasons is that it could have eaten the lion’s share of the TetraMin flake food the day before. I tried dosing Melafix (do not have any other suitable medication). I find that flake food tends to make neon tetras bloated (they may swallow air at the surface), but usually it subsides within a few hours. This tetra has been bloated for one full day, which is quite abnormal according to my experience.

Neon Tetra Bloated Recovery

Good news! The neon tetra recovered from bloat! Its stomach is noticeably more normal sized (previously there was a small lump). I am not sure if it was due to the Melafix or not. It is swimming normally now.

Update: I found out that one way to prevent neon tetra from getting bloated, without pre-soaking pellets and flakes, is to scatter the floating pellets in a wide area around the tank. This allows more time for the pellets to absorb water while the neon tetras are searching around. I found that this is much better than feeding through the “feeding slot” area at the top of my tank lid.

Another advantage is that slower fish can also get a better chance at eating the pellets while the fast neons are swimming around searching for their food. If I drop the pellets in a small area, it is likely that a few neon tetras will gobble up all the food, leaving none for the rest (and those neon tetras will end up bloated).

Convert Lichess Blitz Rating to FIDE

Previously, we have written a blog post on Lichess to FIDE Elo Rating Conversion. The formulae there still hold to some extent, but it is slightly outdated. We have updated the formula (using linear regression), using recent data in Feb 2020.

Conversion Formulae

The formula is:

FIDE rating = (0.8399)*(Lichess Blitz Rating) + 179.8890

For example, if your Lichess Blitz Rating is 1800, then your estimated FIDE rating is:

(0.8399)*1800+179.8890 = 1692

Methodology

We use 30 data points obtained from Lichess.org website through searching the keywords: “FIDE rating:” site:https://lichess.org/@.

We then use R to perform linear regression. The best fit line is shown below.

Code and Output

df <- read.csv("lichessfide.csv")

Alternanthera Reineckii Mini Low Tech

Alternanthera Reineckii Mini (AR Mini) is still surviving after 2 weeks in low tech tank! No CO2 added, basic LED light.

AR Mini Low Tech

This blog post is an experiment on whether Alternanthera Reineckii Mini (AR Mini) can survive in a low tech (i.e. no CO2 supplementation) tank.

The plant used is Tropica tissue culture as shown below:

Traditionally, Alternanthera reineckii ‘Mini’ (AR Mini) is grown in high tech, high light tanks where it will grow into a deep red purplish color. In low tech, lower light tanks, I am trying to see if it can still grow, albeit less red. Maybe a lighter red or olive / bronze color like its cousin Alternanthera Roseafolia (below), would be a good enough result.

Good phrases for Chinese Composition Writing (Secondary school / Top Primary Students)

Using a good phrase (correctly) can instantly add marks for your Chinese Compo (Composition), as it shows that the student is well-versed and adept in using Chinese Idioms/Proverbs.

The more exotic the phrase, the better the effect (when used correctly). Common phrases like “风和日丽” have been used thousands of times and hence do not have a beneficial impact on impressing the teacher (or grader).

Hence, for the hardworking student who wishes to gain marks in Chinese compo, the best strategy is to memorize some good phrases that have a wide range for applications. Then, apply the phrases appropriately in the Chinese composition. A problem for Singaporean students is that they have limited Chinese vocabulary, which in turn limits the marks the teacher can give for the “Vocabulary” section of the Composition. (Basically, the teacher can only give average marks if you use average vocabulary…)

The above source is an excellent handbook on Chinese composition, which contains many good Chinese phrases. We post selected excerpts here in case the original website is down.

Michelle Chong Ad (Elite School Funny Video)

Michelle Chong’s portrayal of a student from an elite school in Singapore (not hard to guess once you watch the video) is fantastic!

LOL at the amazingly funny line “are you from my rival school, the one with the sleeveless uniform”? (Hinting at another elite school in SG, again not hard to guess.)

The portrayal is quite realistic to be honest!

Review: 10/10 Must watch!

Mega Database of JC Prelim Papers

This weirdly titled Google Drive (“Electric Boogaloo”) contains a mega-database of JC Prelim papers for most if not all subjects, even esoteric subjects like “Theatre Studies and Drama”. Exam papers ranges from H1 to H3, and from the years 2008 to 2019.

We have included the above link in the Free Exam Papers / Free Test Papers page, containing other large sources of Free Exam Papers.

Wuhan Virus Swimming

This post is all about whether the Wuhan coronavirus can spread in swimming pools. It is a top search in Google, however there is currently zero information about it.

We will list down various sources on other types of similar flu viruses and whether it can spread through swimming pools.

Source 1: Poolman.com (Yes!)

The short answer is yes. As Every Day Health summarized, germs that cause the flu and other illnesses spread so fast because people transmit it by simple motions, like a sneeze or a cough. Everyone from children to coworkers to spouses can be culprits. If any of them uses the pool, it can easily get to you.

Source 2: Illinois Department of Public Health (Maybe, not conclusive)

No research has been completed on the susceptibility of H1N1 influenza virus to chlorine and other disinfectants used in swimming pools, spas, water parks, interactive fountains and other treated recreational venues. However, recent studies have demonstrated that free chlorine levels recommended by CDC (1–3 parts per million [ppm or mg/L] for pools and 2–5 ppm for spas) are adequate to disinfect avian influenza A (H5N1) virus. It is likely that other influenza viruses such as H1N1 virus would also be similarly disinfected by chlorine.

Source 3 (Channel News Asia):

Q: Can the virus be spread through water such as via swimming pools? Or through one’s eyes?

Prof Gray: We don’t know, but other respiratory viruses can, such as adenovirus which is a hardier type of virus.

Prof Wang: Transmission through the swimming pool is unlikely unless the person is swimming very close to an infected person. Yes, it is possible to be infected through the eyes.

Asst Prof Anderson: It is unlikely that the coronavirus can be spread through water, especially chlorinated swimming pools. Coronaviruses are also not known to be spread though the eyes.

There is an anecdotal case of infection through the eye and, if this infection did occur, it is an extremely rare event.

Conclusion

It is basic chemical knowledge that chlorine in pools is a powerful disinfectant. At high concentrations, chlorine is capable of destroying any living thing, not just Wuhan virus. However, swimming is not 100% underwater, there is a period of walking into the swimming pool, as well as breathing above water. During those periods above water, it is possible for the Wuhan virus to be transmitted. Also, if the chlorine concentration is not strong enough, it may not be enough to disinfect the virus.

Hence, it is better to be safe and avoid swimming pools during this period!

You may first check out the nearest Guardian, Watsons or Unity near your place. Most likely, Guardian and Watsons are out of stock already, while Unity has a long queue. (I personally checked them out on 28 Jan near my place.)

Do check out the terms and conditions before joining the long queue at Unity. (They will put a poster in front of their store.) Apparently the queue at Unity is only for those who have pre-ordered masks beforehand!

The next best option is to buy online, specifically from Qoo10 since they have stock from Korea. I ordered these two listed below which are decently priced (some sellers are taking advantage of the situation to raise up the price). Korean masks are said to be higher quality and more comfortable to wear.

Basically, the best type of mask is N95 but they are expensive. Surgical mask is cheaper and is said by experts to be good enough for preventing the Wuhan virus.

Due to overwhelming demand, even online sellers on Qoo10 are running out of stock. The next option is to buy US surgical masks from Amazon. The below are good options:

• Barcley is the #1 Best Seller in the Medical Face Masks Category

N95 masks are actually more powerful than surgical masks. The only downsides are that they are more expensive and also more uncomfortable to wear (over long periods of time). N95 masks are so named because they can block 95% of particles of size 0.3 micrometers. This is according to the US NIOSH air filtration rating.

Note that N95 masks can be reused as long as it “maintains its structural and functional integrity and the filter material is not physically damaged or soiled.”. The CDC (USA Centre of Disease Control) also recommends reuse of N95 masks to a certain extent (defined as “limited reuse”).

Since surgical masks are the top candidates for purchase, it is often the case that surgical masks are sold out first, while N95 masks may still be in stock. A top manufacturer of N95 masks is 3M, which is based in the US. Hence, purchasing N95 masks from Amazon is cost-effective in the sense that it is right from the source of the manufacturer (3M).

AR Mini Low Tech

This blog post is an experiment on whether Alternanthera Reineckii Mini (AR Mini) can survive in a low tech (i.e. no CO2 supplementation) tank.

The plant used is Tropica tissue culture as shown below:

Traditionally, Alternanthera reineckii ‘Mini’ (AR Mini) is grown in high tech, high light tanks where it will grow into a deep red purplish color. In low tech, lower light tanks, I am trying to see if it can still grow, albeit less red. Maybe a lighter red or olive / bronze color like its cousin Alternanthera Roseafolia (below), would be a good enough result.

Tank Parameters and Fertilization

Tank size: 5 Gallon (I am using this tank: Ripples Premium Aquarium Glass Fish Tank (with Filter and LED Lights) 18.9L)

Light: It is just a basic starter kit LED light with 7 bulbs. Apparently rated just 2.9W.

Substrate: Aqua Gro Aquarium Soil by Ocean Free (it is a local brand by Qian Hu). It should be something similar to ADA Aqua Soil Amazonia II Normal Type (9L), maybe with less nutrients.

Fertilizer: So far I am only using Tropica Plant Growth Premium Fertiliser – 125 ml, one pump per week after water change.

Lighting schedule: I am using an electronic timer with 12 hour photoperiod: 10am-4pm, 5pm-11pm. In between 4-5pm is a siesta (rest/blackout) period (to build up some CO2 if possible).

Videos

Day 1 (23 Jan 2020): This is the first day of planting. Still quite purplish undertones. To plant the Tropica tissue culture, I plucked off some of the leaves on the lower stem, and then inserted it into the substrate. No trimming of roots were done (the roots were not long anyway).

Day 3: The next video below is the 3rd day. The pinkish red colors on the underside are mostly gone (quite worrying), but the plants is clearly alive and it has oriented its leaves to face upwards! It is now a olive color with hints of red/pink.

Day 4: Video below. Not much different from Day 3. I realized that there is a Dwarf Sag small plantlet with runner amongst the AR Mini. The Dwarf Sag is one plant that is thriving in the tank. It started with 2 mother plants and now there are at least 8 plants propagated naturally via runners. If necessary, I may remove the dwarf sag (just the one amongst the AR Mini).

Day 5: Melting and shedding of leaves. This is day 5 of planting the AR Mini in the low tech tank. A total of 3 leaves were shed today. I think it is either (a) transitioning from emersed to submersed growth or (b) dying. Hopefully it is the former!

Day 6: Just one leaf melt today. One entire stem got uprooted, maybe it was the snail or the shrimp that disturbed it. There is a little frenzy among the neon tetras and Amano shrimp trying to grab the shrimp pellet. I removed a dwarf sag plantlet among the AR Mini, and replanted the uprooted stem there.

Day 7: No shedding of leaves today, which is good news. I spotted something that looks like hair algae, it could well be a disintegrated Marimo moss ball from “Secret Shrimp Society”. Water change was done, as well as dosing of Tropica Premium Nutrition liquid fertilizer. I ended up trimming the Cryptocoryne Wendtii as its leaves were almost reaching the water surface. I also removed the disintegrated Marimo moss balls from “Secret Shrimp Society” as it was starting to look like hair algae.

Day 10: This is day 10 of growing Alternanthera Reineckii Mini in a low tech tank. The leaves seem to have “perked up” and are slightly pinkish. Overall it looks better than on day 7, I think. The contrast between day 3 is also quite clear. No CO2 in this tank.

Day 13: The AR Mini has changed to a nice orangey-red. There has been shedding of around one leaf per day. The plant still looks alive overall, and in fact has grown taller than the Dwarf Sag beside it. There has been some trimming of the taller plants in the tank (crypts and Anubias).

Day 16: It has passed the 2 week mark. The AR Mini is still alive in the low tech tank. I do observe some new leaves growing.

Day 20: The AR Mini plants are getting more bronze color and less red. The undersides are still a little pinkish red though. Overall quite surprised at the result in my low tech tank. (I was half expecting the plants to die.)

Further Ideas

I may add some root tabs in the future (will clearly indicate the moment when I do add it). According to the below video review (it is really excellent), the best root tab on the market seems to be Seachem Flourish Tabs Growth Supplement – Aquatic Plant Stimulant 40 ct.

LaTeX Horizontal Flowchart (Workflow)

Just bought this red plant at a local fish store at just $2. I am thinking it is Ludwigia repens (or possibly other type of Ludwigia). Red plant (Ludwigia repens?) in low tech 5 gallon tank. No CO2. I bought this red stem plant for my fish to celebrate Chinese New Year. Hope it can survive in my tank! Update: Unfortunately, upon further research, the above red plant may actually be Alternanthera sessilis which is not aquatic! The stems and leaves of the above said plant are quite hard and stiff, which is characteristic of a terrestrial plant. I have tried to ask experts on the Planted Tank Forum, they have confirmed that it is not Ludwigia arcuata (which I originally thought it was).

“Toxic environment” in Elite Secondary School (Singapore)

Just came across this Facebook post (originally by Pamela Lim):

For convenience, the post is reproduced below. Although the school is not explicitly named, it is quite easy to guess from the description which school it is! (It is probably a school that “offers a highly accelerated mathematics and science curriculum integrated with language, arts, humanities, sports, in a modular system.”)

Case study:

Anthony’s PSLE result was sterling and he got into an elite of elite secondary school, one that promises more than academic rigor, their high school credits can be used as credit transfers into a top university in Singapore.

Needless to say, it is a sought after secondary school, and the kids are studying 3-4 years ahead of their age peers in the areas they specialize in.

The celebration was short-lived. Within six months, the parents reached out to me. The high IQ child has school refusal problems. So I got our counselors involved to see how we can help.

Our advice was to remove him from a toxic environment where kids are often driven to a place where they feel deflated, over challenged and unaccomplished. We feel he should go to where his gifts are appreciated, where he can score well and his self-esteem is high. On the side, we promised to offer enrichment that will challenge and stimulate his intellectual needs. We felt he needed both social and intellectual support, and since he cannot get them both in the same place, we suggest splitting them.

Not unexpectedly, the parents and child felt that it was a ‘waste’ to give up a prestigious school, so they stayed. Yesterday, we received another call. In the six months since we last spoke, the child moved to an international school, and now refuse to go to the new school as well. In fact, he is refusing to get out of the house, so can we send in some psychologist.

To be honest, I don’t think we can ‘rescue’ a child like that, no matter how much they offer to pay us. He is only 14, and just 2 years ago, he was acing his cohort, happy about his situation, full of confidence of his future.

Just a disclaimer that “Toxic Environment” is a subjective term, one man’s meat can be another man’s poison. However, the fact of the matter is that many schools (especially elite schools like IP schools) do have high academic stress. The level of the internal tests in top IP schools is much higher than ‘O’ level standard. It is quite common for top students in PSLE to “fail” those tests in the elite IP schools, especially if they can’t adapt quickly to the style of tests.

Most notably, in top IP schools, what is tested in exams is quite often not taught in class! Students are expected to extrapolate the basic material taught in class, to tackle the tough questions in exams. Basically students need to 举一反三！(The teacher teach you one thing e.g. 1+1=2, the student needs to extrapolate and deduce for yourself 3 other things e.g. 1+2+3+…+99+100=5050.)

Needless to say, only minority of students (even in top schools) are capable of the above. Hence, that is why self-learning in the form of challenging assessment books or tuition has become quite popular as it is one way of overcoming the “teach simple, test difficult” style in top secondary schools or JCs.

How to speak to Human Singtel Customer Officer

Just to reblog this post on how to contact a human Singtel customer service operator. Do share it with your friends/relatives as it can be **extremely** difficult to contact Singtel during times of need.

If you try calling the Singtel hotline 1688, you will spend most of your time to navigate the maze of options trying to speak to a human Singtel Customer Officer. I have not managed to successfully find the option to speak to a human Singtel Chat Agent through the hotline, if you know the method please comment below!

Also, do not bother speaking to “Shirley” on the Contact Us page (https://www.singtel.com/contact-us). It is quite clear Shirley is not a human, but just a bot.

The Trick to Chat with a Human Singtel Customer Officer

3. Type “can i chat with customer service officer”.
4. Type in the category of your question, e.g. “billing”, “voucher”, etc.
5. Whatever Shirley says, just click “Submit Enquiry”

O Level Higher Chinese Distinction Rate

Quite surprising to see news on Kiasuparents that the distinction rate for ‘O’ Levels HCL is so low.

Case study 1)

In the below case study, zero students scored A1 for Higher Chinese in the recent O Levels. This is very surprising since even in neighborhood schools, we would expect there to be at least a few students strong in Chinese. For example for Mathematics, even in neighborhood schools there is guaranteed to be at least a few students scoring A1.

In my DD’s (dear daughter) school, no one scored A1 for Higher Chinese for the recent GCE O Levels.

This is very surprising becos there are students who are very academically inclined and some have shown consistent strength in the subject over the 4 years in secondary school.

I wonder how other secondary schools perform in this subject. Or did MOE raised the standard or the school is just unlucky where their students exam papers were marked by an unusually strict examiner/marker?

Case Study 2)

The below case study is also very surprising since SAP schools are known to have a heavy emphasis on Chinese language and culture, usually leading to excellence in the Chinese subject. Examples of top SAP schools include Dunman High, Catholic High, Chung Cheng High School (Main), etc.

The distinction (rate) for HCL in my DS school is 29.6%. Considering that he is from a SAP school with strong Chinese culture.. this is quite low.. but to be fair.. with 8-9 subjects to manage and knowing that C6 will get you the 2 bonus points.. how many kids will aim for A1? My DS got C6 and he is happy that he got his 2 bonus points..

Boeing mocked Lion Air calls for more 737 Max training before crash

Source: Straits Times

JAKARTA (BLOOMBERG) – Indonesia’s Lion Air considered putting its pilots through simulator training before flying the Boeing 737 Max but abandoned the idea after the planemaker convinced them in 2017 it was unnecessary, according to people familiar with the matter and internal company communications.

The next year, 189 people died when a Lion Air 737 Max plunged into the Java Sea, a disaster blamed in part on inadequate training and the crew’s unfamiliarity with a new flight-control feature on the Max that malfunctioned.

Quite unbelievable that such lack of regard for safety was demonstrated by Boeing. Note that the above news is taken from a major newspaper in Singapore, the Straits Times.

Another news by Bloomberg: Boeing’s 737 Max Software Outsourced to $9 -an-Hour Engineers. The real reason Boeing 737 Max crashed twice is a software problem! According to the video below, the real reason why the Boeing 737 Max crashed twice is none other than a software problem! (The software called MCAS keeps pushing the nose of the airplane downwards.)
