StarHub Down

Is StarHub down?

The answer is yes! Please see the official news by Today: StarHub customers hit by major fibre service disruption.

It is also reported by Straits Times that, yes, StarHub is down.

StarHub Network Down (Solved)

I stumbled upon the solution to solve the issue of “Starhub Network Down”. Note: This applies if your Starhub Network is slowed down but not completely dead/inaccessible.

Solution: Google DNS

My StarHub internet slowed down to a crawl, it took almost forever to access a simple website like Gmail or Yahoo. Hence, it can be classified as “StarHub Almost Completely Down“.

Upon changing to Google DNS using this official Google guide, to my astonishment the internet sped up to be even faster than before the “StarHub Down” issue.

Speed test of StarHub internet speed (after changing to Google DNS) on the day that StarHub was supposedly down!

I am not exactly sure of the mechanism behind, but changing to Google DNS certainly solved the issue of “StarHub Internet Down” for me. I suspect that due to the StarHub network down issue, most of StarHub remaining working “servers” are overcrowded and overloaded. Hence, if you switch from the StarHub DNS to Google DNS, you are leaving the “crowded server” and that explains the faster speed.

For record, I used the following Google DNS (IPv6):

2001:4860:4860::8888 and  2001:4860:4860::8844.

For safety concerns, it is considered quite safe to trust Google DNS. (Read their details on Wikipedia.) Basically, if you are already using Google products like Gmail, Google search engine, you might as well use Google DNS.

Education/Math/Science Niche Website Directory

I have recently created a Education/Math/Science Niche Website Directory at: https://mathtuition88.com/education-website-directory/.

Currently, it is free to submit to this directory! (Just need to provide a link back to our website.) Benefits of submitting to this link directory include a valuable dofollow backlink from our Page Rank 4 website, mathtuition88.com. Basically, Page Rank determines how high your website is ranked on search engines like Google. The more quality backlinks a site has, the higher the website’s Page Rank, and the higher it will rank on Google. Ranking on the first page of Google is an incredible way of getting organic and highly targeted traffic from the search engines.

The blog directory will be only accepting Education/Math/Science websites hence it is a niche blog directory. Evidence have shown that blog directories which are reviewed and curated, and from a niche topic is highly beneficial to SEO (Search Engine Optimization). Furthermore, Page Rank from our blog will add to the links submitted, and raise the Page Rank of the websites listed on the Blog Directory, and also vice versa.

Hence, do submit to this directory if you are interested to boost your search engine rankings, and have more people find your blog or website. 🙂

Also, do check out our latest blog posts:

Finally, if you are using Android or Amazon Kindle, do check out this free Math app MathOpen Cool Math Kids Game. Preschool to 5th Grade. It has cool Math games and exercises for children aged preschool to 5th Grade.

Gmail iOS update adds iPhone 6 support and a math joke

You may need to brush up on your math if it seems odd to you that Google just updated the iOS Gmail app to version 3.1415926.

But Google is definitely not the type of company that turns down an opportunity to make a math joke, even when that joke is as simple as naming an app update after pi.

Besides that, the Gmail for iOS update has a single improvement: support for the iPhone 6 and iPhone 6 Plus.

Shakuntala Devi\'s 84th birthday: Google doodles a calculator for the human computer

New Delhi: Google is celebrating the 84th birth anniversary of mathematical genius Shakuntala Devi, nicknamed “human computer” for her ability to make complex mental calculations, with a doodle on its India home page.

The doodle salutes Shakuntala Devi’s amazing calculating abilities with a doodle that resembles a calculator.

Shakuntala Devi found a slot in the Guinness Book of World Record for her outstanding ability and wrote numerous books like ‘Fun with Numbers’, ‘Astrology for You’, ‘Puzzles to Puzzle You’, and ‘Mathablit’. She had the ability to tell the day of the week of any given date in the last century in a jiffy. Coming from a humble family, Shakuntala Devi’s father was a circus performer who did trapeze, tightrope and cannonball shows.

Puzzles to Puzzle You

Mathematician gives evidence at the O.J Simpson trial, helped find diamonds and now is determining the cause of cancer.

Who says Mathematics is useless? It can be useful one day in your career, or just for increasing your general knowledge.

The man who last night won the Prime Minister’s Science Prize agrees maths is “not sexy” but it saw him give evidence at the O.J Simpson trial, helped find diamonds and now is determining the cause of cancer.

Mathematician Professor Terry Speed was called as an expert witness for O.J. Simpson in the famous 1995 murder trial where he helped explain to the jury how statistics underpinning DNA worked.

Simpson was acquitted after a trial that lasted more than eight months because his lawyers were able to persuade the jurors that there was reasonable doubt about the DNA evidence.

Forty five years ago Professor Speed testified at the trial of Ronald Ryan, the last man to be hanged in Australia.

He had to explain the geometry of the trajectory of bullets in the case.

In an extensive career the 70 year old statistics whiz has helped determine the size and distribution of Argyle diamonds and looked at kangaroo genomics.

Right now he is working at the cutting edge of medical science helping scientists develop statistical tools to understand the huge volumes of information coming from the human genome.

Work he’s done for a company on a thyroid cancer diagnostic test could help prevent thousands of people from having their thyroids removed unnecessarily.

At present some thyroid tests are inconclusive and tumours are removed even though they turn out to be benign leaving the patient taking hormone replacement therapy for the rest of their lives.

Some of his work is in developing tools that find which genes or gene characteristics may cause cancer if they are switched on or off.

Professor Speed says part of the reason so many people don’t want to study maths and science is they don’t see its potential.

He’s spent his life applying mathematical theories to crime, farming, mining and medical science.

Sergey Brin, co-founder of Google, studied Mathematics!

Maths Group Tuition to start in 2014!

Sergey Mikhaylovich Brin (Russian: Сергей Михайлович Брин; born August 21, 1973) is an American computer scientist and Internet entrepreneur who, with Larry Page, co-founded Google, one of the most profitable Internet companies.[4] As of 2013, his personal wealth was estimated to be $22.8billion.[2] Together, Brin and Page own about 16 percent of the company.

Brin immigrated to the United States with his family from the Soviet Union at the age of six. He earned his undergraduate degree at the University of Maryland, following in his father’s and grandfather’s footsteps by studying mathematics, as well as computer science. After graduation, he moved to Stanford University to acquire a Ph.D. in computer science. There he met Larry Page, with whom he later became friends. They crammed their dormitory room with inexpensive computers and applied Brin’s data mining system to build a superior search engine. The program became popular at Stanford and they suspended their PhD studies to start up Google in a rented garage.

The Economist newspaper referred to Brin as an “Enlightenment Man“, and someone who believes that “knowledge is always good, and certainly always better than ignorance”, a philosophy that is summed up by Google’s motto “Organize the world’s information and make it universally accessible and useful”[5][6] and “Don’t be evil“.

Education in the United States

Brin attended grade school at Paint Branch Montessori School in Adelphi, Maryland, but he received further education at home; his father, a professor in the department of mathematics at the University of Maryland, encouraged him to learn mathematics and his family helped him retain his Russian-language skills. In September 1990 Brin enrolled in the University of Maryland to study computer science and mathematics, where he received his Bachelor of Science in May 1993 with honors.[14]

Tip: Using Google “filetype” filter to search for Free Exam Papers

This is a handy tip to search for Free Exam Papers on Google.

(Note: Google is very powerful, but it can only search for exam papers that are already online in the first place)

Since most exam papers are in PDF format, we can restrict our search to PDF files by adding the phrase “filetype:pdf” to the Google search.

For example, searching “hwa chong maths sec 2” in Google does not yield many exam papers.

Searching “hwa chong maths sec 2 filetype:pdf” returns a much better result, including some worksheets and test papers.
