Solve This Mathematical Code

keith — Mon, 13 Oct 2008 16:44:52 +0000

A man wanted to get into his work building, but he had forgotten his code. However, he did remember five clues. These are what those clues were:

a.. The fifth number plus the third number equals fourteen.
b.. The fourth number is one more than the second number.
c.. The first number is one less than twice the second number.
d.. The second number plus the third number equals ten.
e.. The sum of all five numbers is 30.

Question: What were the five numbers and in what order?

Imaginary Number Comic

keith — Mon, 19 May 2008 07:46:39 +0000

This is quite a funny comic strip about imaginary number. Well, first of all, I’ll like to say that I have not forgotten about this blog. Secondly, I plan to revive this site once I get my hands off my work, so that I have more time to cater to the community.

Meanwhile, here is quite a funny joke about imaginary number.

Site Engine Upgrade for TestBed

keith — Sat, 24 Nov 2007 07:19:56 +0000

Taking a look at the date of my last post in this TestBed blog, I am certainly guilty of neglecting this site, for ages! It is about one year (November 2006) since a post was last made (or published) here.

Since, I am doing some spring cleaning on the web server, I might as well perform some script upgrades on this site. There may be few visitors from time to time, but it is still vital to ensure that the scripts are up-to-date, so as to avoid any malicious hacker’s attack or security flaw issue.

Hence, the latest WordPress version is deployed and new plugin versions replacing the old ones. Now, the site is as good as new!

Human Minds are the Living Artificial Neural Network

keith — Thu, 30 Nov 2006 11:21:34 +0000

This is all part and parcel of the human brains being able to interpret the jumbled up words in a paragraph. A lot of factors come into play, including length of the word, smooth-flowing sentence, the first and last letter placed correctly, commonly used word (and names), etc…

fi yuo cna raed tihs, yuo hvae a sgtrane mnid too.
Cna yuo raed tihs?

i cdnuolt blveiee taht I cluod aulaclty uesdnatnrd waht I was rdanieg. The phaonmneal pweor of the hmuan mnid, aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it dseno’t mtaetr in waht oerdr the ltteres in a wrod are, the olny iproamtnt tihng is taht the frsit and lsat ltteer be in the rghit pclae. The rset can be a taotl mses and you can sitll raed it whotuit a pboerlm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe. Azanmig huh? yaeh and I awlyas tghuhot slpeling was ipmorantt! if you can raed tihs forwrad it.

Amazing isn’t it? In some way, our human brains work like probabilistic model describing the most probable outcome from a noisy data, such as the paragraph above. It is just amazing how powerful our brains have been trained and adapted to the environment around us.

Publication using w.bloggar

keith — Sat, 14 Oct 2006 17:30:00 +0000

After looking around the Internet in search of a compatible weblog client, I finally bumped into w.bloggar. As I would suggestion BloGTK for Linux users, Windows users would probably find w.bloggar a good choice for publishing to Blog.

Trial Submission using BloGTK

keith — Thu, 12 Oct 2006 09:26:42 +0000

This is a trial test to using XML-RPC functionality in MovableType API to submit a post to WordPress. If this works, it is going to be extremely helpful.

Some HTML tags here:

First unordered list - to ensure it works
Second in the list - has to work

BloGTK 1.1 is the current version of this engine.

WordPress Gallery Plugin - developed by Al Carlton

keith — Wed, 04 Oct 2006 09:27:32 +0000

Al is an excellent friend; very generous minded and friendly as well. He has great interest in running his own sites, and some of them, such as Coolest Gadgets and SoftSift has soared to great heights after a few months they were launched, particularly the former.

As a programmer by nature, he has also developed a WordPress Gallery Plugin for some of his blog sites. To avoid confusion, there is also another kind of WordPress Gallery plugin in the World Wide Web (WWW), however though the naming is the same, their functionalities are different. Not sure if Al may consider changing the name of his plugin, but the tool that he’s developed is excellent.

The WordPress Gallery Plugin allows blog visitor to see a visual summary of the latest posts. The idea of having this plugin is to generate a post that reflects the summary of the past few posts that the authors of the (WordPress) blog site have made. In terms of search engine rankings, it also helps to provide more internal linking to improve search engine optimisation (SEO) ranking.

Basically, how the plugin works, is very simple. The plugin first generates a new post containing images and links to the latest recent posts made, and these images are scaled properly to thumbnail sizes, so that they look better than just scaling HTML. Since they are scaled, they are much smaller and faster to load. Once generated, the post is marked as draft on your WordPress Dashboard. To post, simply edit that post and click on Publish.

This plugin also has some configurability to the various options, e.g. number of recent posts. Try it out and you will see how simple it looks.

Download Link
I will not put a hotlink to the plugin download here, as I’d like to credit the work done by Al. There are documentations on his site. So, if you are interested in this plugin, check out the original WP Gallery Plugin page.

Examples
Some of the examples are available here:

Singapore Style Comic Strip

keith — Tue, 19 Sep 2006 13:42:29 +0000

Each and every nation has their own culture and characters, and it goes the same for comics strips as well. This is a fairly old comic strip sent to me, and I think they are very Singaporean-like in terms of style and language.

The characters are quite exaggerated, but it goes the same as how Bart Simpsons or the South Park was created. Each comic writer has their own originality, and I find it pretty good for light laughter.

No 1.

Young Mathematics Genius

keith — Sat, 16 Sep 2006 13:03:16 +0000

To keep this site lively and not just pure serious mathematics, I have created another category to entertain myself and the audience, Leisure. Ever wonder how Einstein fare during his younger days, or even Newton’s work out gravitational laws of forces.

Sometime, while we might have came across complicated mathematics, ranging from Cauchy’s complex numbers theorem to Kalman Filters. In this post, we see the other side of Mathematicians.

Behold the Power of Hamachi - VPN Networking

keith — Sat, 09 Sep 2006 14:43:32 +0000

I have been introduced to Hamachi for quite some time, and I find it extremely useful and interesting. This software is, by no means, a utility that you should go without, especially you someone who is always on the move, and requiring to access your home personal computers (PCs) or workstations that resides behind a firewall or NAT (Network Address Transversal) router.

Introducing Hamachi, a zero-configuration virtual private networking (VPN) application that allows users to arrange multiple computers into their own secure network, as if they were connected by a physical network cable. Typically, there are platforms for Windows, Linux and Mac OS X, and their installers can be downloaded directly from here. More information is available here at SoftSift.
