STI off 1.5%, ‘Run first, think later’, says analyst

Written by The Edge
Wednesday, 28 April 2010 12:44
Pullback in Singapore shares fails to generate bargain-hunting as investors unsure how Europe’s sovereign debt problems will pan out following Standard & Poor’s rating downgrades, says Dow Jones.

The STI down 1.5% at 2,947.02 midday, barely above last week’s low of 2,943, which still stands as immediate support. All FTSE ST sub-indexes remain negative, with market breadth at six decliners for every gainer.

“What we saw yesterday on the news of Greece’s downgrade is a sudden shift from risk appetite to risk aversion. Akin to someone shouting ‘fire’ in a crowded cinema, it provokes a ‘run first, think later’ reaction,” says Phillip Securities analyst Phua Ming-Weii.

On brighter note, volume light at 906.9 million shares, suggesting selling pressure contained. Rig builders, Singapore Exchange (S68.SG), Fraser & Neave (F99.SG), Jardine group lead decline among blue chips.

Google Android will prevail over Apple's iPhone and RIM's BlackBerry

An interview by the New York Times with Google’s Andy Rubin on the topic of Android revealed that the coming Android 2.2 will come with full support of Adobe Flash. This is after Adobe decided to ditch Flash for the iPhone and concentrate on Android. Rubin predictably said that the Android platform was taking off because it was open to many manufacturers running many different architectures. He also predicted the sales of Android phones to exceed the sales of proprietary systems like Apple’s iPhone and RIM’s BlackBerry, and of which I concur with.

Yesterday, mobile ad network AdMob, published a mobile metrics report for the month of March in U.S. showing Android web traffic exceeds all other smartphones, including Apple's iPhone. The potential for Google Android to be the dominant force in smartphone is real, especially with its openess concept. Photoshop is now available on Android, Android is able to run on Apple's iPhone, and now full Flash support on Android, what else can stop Google's Android from dominating?

At the end of the New York Times' interview, the interviewer joked with Rubin that his press relations colleague, who was in the room, wanted to confess that he had left a prototype Android phone at a local bar. Mr Rubin's reply was as such
I’d be happy if that happened and someone wrote about it,” Mr. Rubin said. “With openness comes less secrets.
I wonder what will happen or had happened to the poor guy who lost Apple's iPhone 4.0 prototype phone in a pub weeks ago.

Alien Invasion: Why Stephen Hawking is Wrong

When one of the highest regarded cosmologist cum physicists - Stephen Hawking speaks, we should take heed. Sir Stephen Hawking talked about the possibility of alien invasion.

If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans.

He is also certain that alien life exists in other parts of the universe and uses a mathematical basis for his assumptions.

To my mathematical brain, the numbers alone make thinking about aliens perfectly rational. The real challenge is to work out what aliens might actually be like.

So, just how true is his statement on the existence and nature of extraterrestrial life?

Sir Stephen Hawking, whom I used to read about during my secondary school days, is one of my most respected scientist.

New fare policy is fairer, says transport council

Even though some commuters may find that they do not benefit from distance fares immediately, the travel patterns of all commuters may change over time as people change their homes and places of work and new MRT lines are built. The new fare structure will therefore benefit all commuters as they will have greater travel options that include transfer journeys when their travel patterns change in future.

The transport council seems to suggest we change homes like change clothes. I wonder how far is the 'future' as mentioned by the transport council.

Singapore government takes on Al Jazeera for misreporting on homelessness cases after the latter was axed

The Singapore government takes on Al Jazeera for misreporting on homelessness cases after Al Jazeera was dropped from SingTel Mio TV (paid-TV) from April 1.

The reason cited by the Singapore government for dropping Al Jazeera was due to low subscription, despite many speculating Al Jazeera's many unflattering stories about Singapore could be the real reason. Al Jazeera had made stories about prostitution and homelessness in Singapore.

Purely coincidental? It is up to the public to decide.

1.5 Million Facebook Accounts for Sale in Web Forum, VeriSign Reports

VeriSign iDefense, which uncovered a cyber-crook on an electronic fraud forum selling 1.5 million Facebook accounts at a price of $25 per 1,000 accounts with 10 contacts or less. For accounts with more than 10 friends the going rate was $45 per 1,000.

We as users of Facebook signed up for accounts for free but yet crooks can use these free accounts for a profit. This shows just how valuable data-mining on private information is.

My last flight

Today is my 15th and the last flight on a Fokker 50 aircraft. Maybe the god knew of it and deliberately set things up to make the flight unique and different from my previous 14 flights.

First, the duration of the flight, excluding taxiing, is a record - 5.9 hours. The duration could have brought me to Taiwan or Australia.

Second, due to some unknown reason, only one runway in Changi was left operational. For this reason, taxiing and queuing up for take-off already took me a good long 40 odd minutes.

Third, I spot two food menu that I had never tried before. They are "Black pepper chicken western set" and "Chinese Szechuan chicken set". Yummy!

Can I exchange my flights hours for the 15 flights for KrisFlyer miles? Fat hope!

Mother tongue weighting in PSLE could be cut

Singapore's Education Minister Ng Eng Hen says his ministry is studying whether it is educationally sound for mother tongue language performance to count for so much at the Primary 6 PSLE level. Since the Mother Tongue language now carries equal weight as the other three, then why is Singapore finding it to be too much?

'The worry is whether it could exclude someone from progressing in his educational pathway even if he did well in other subjects,' said Dr Ng in an interview with The Straits Times and Lianhe Zaobao.

If the reason for lowering the weighting is due to many not doing well in the language, then this is really disappointing of Dr Ng. Instead of lowering the weighting, students should be encouraged and motivated to do better in the language. If one day students do not do well in English, does this mean weighting of English language would be lowered as well?

Let's not be quitters!

New distance-based fare system will see public transport fares to go down by 2.5% from Jul 3

Bus and train fares will be reduced by 2.5 per cent from July 3 when the Public Transport Council (PTC) introduces a new distance-based fare system.

Summary on the changes
  • Fares will be reduced by 2.5% from 3 July 2010
  • The 15-month fare discount of 3% will end on 2 July 2010
  • No more transfer rebates

For more information on the distance fares, please refer to the Public Transport Council website ( and click on the red "Fare revision" tab on the front page.

An interesting study by the PTC titled "Instituting Fare Regulation" reveals a rather bemusing fact.

Believe it or not, PTC claims the real monthly expenditure on transport actually drop for the past few years.

In addition to earlier post on "Uncertain trading week ahead"

To add onto my earlier post on the topic of "Uncertain trading week ahead", we should not forget the current European skies standstill due to the Icelandic volcanic eruption. The Iceland volcano ash cloud, costing the airline industry US$200 million per day, could just push the European airliners to the brink. Other airliners could see their balance sheets affected after several flights to and fro Europe cancelled. Airliners have also been providing daily monetary aids and not since vowed not charging carry-baggage fees for passengers travelling to and fro Europe. A total of 63,000 flights were cancelled since last Thursday.

The current Europe sky shutdown is the longest and widest since World War 2.

Uncertain trading week ahead

With Goldman Sachs being charged by the US Securities and Exchange Commission for fraud in connection with the creation of complex financial products that were sold in the market. Shares of Goldman Sachs plunged more than 10 percent in just the first half-hour of trading after the suit was announced last Friday morning. They closed down 13 percent, at US$160.70, wiping away more than US$10 billion of the company’s market value. It is suspected that Goldman Sachs, despite knowing the flaw in the structured financial products that resulted investors to lose money, continued selling and marketing the product to the general public. Could Goldman Sachs' case be the tip of the iceberg, signalling the start of Wall Street's legal troubles stemming from the subprime meltdown? Other investment banks may be investigated to determine if they were also involved in creating similar products.

From tomorrow onwards and weeks to come, many companies will be releasing their quarterly financial results. This should add onto the already jittery stock market, especially the financial banks' sector.

My Research Paper - Comparison between 2 models of K-Anonymity: Incognito and Mondrian


Comparison between 2 models of K-Anonymity: Incognito and Mondrian


Often organizations publish microdata for purposes such as public health and demographic research. Although attributes that could identify the individuals such as names and IDs are removed, by combining information (such as Zipcode and Birthdays) within different database, these individuals could still be identified through “Joining Attacks” – Combining 2 different database by cross-linking the similar information.

K-Anonymity has been proposed as a mechanism for protecting privacy by generalizing or suppressing certain portion of the released microdata. There had been several models of K-Anonymity since, each release attempts to improve the previous version’s weaknesses. In this paper, we will compare 2 models of K-Anonymity, namely Incognito (full-domain generalization) and Mondrian (multidimensional model), in terms of their effectiveness as well as their performance.

SMRT target price raised to $2.50 by UBS, keeps ‘buy’ call

Past 1 year performance for SMRT Corp (S53.SI)

UBS has raised SMRT’s (S53.SG) target price to $2.50 from $2.15, based on discounted cashflow model, to reflect higher rail ridership with second phase of Singapore Circle Line opening from April 17 and more people turning to public transport as cost of vehicle ownership escalates, according to Dow Jones.

The broker expects Circle Line’s daily ridership to increase to 211,000 commuters from 38,000 currently when new stations open, which also expected to boost rental, advertising revenue.

UBS adds that Singapore government’s move to cut number of vehicle certificates of entitlement will aid SMRT as public transport becomes more attractively priced vs private modes of transport.

Keeps “buy” call. Shares +0.5% at $2.17.

My comment on the use of pompous and bombastic sentences

Was doing a quick search on the use of pompous English terms "onomatopoeia, alliteration, assonance" and I found this.
...The words tumble so fast, enwrapped in alliteration, clogged with onomatopoeia, choked with assonance, bursting with bombast, snarled with metaphor, tangled with simile, submerged in verbiage that the bombarded audience (and reviewer at a critics' preview) missed about three out of every four...
Though the use of such bombastic words may make one sound poetic and of high intellect, everything will just go down the toilet bowl and choked without anyone comprehending them. There is really no point perpetuating elitism by justifying pomposity in the common language. In writing, I strongly feel one should restrain yourself and keep it lean, targeting the common public, especially if the objective is to reach out to the majority public. There's really no point throwing ammunition of torrential vocabulary to create an illusion of intellectual form over substance.

Such "meticulous" use of vocabulary reminds me of "highfalutin" and "astroturfing", used by the two Singapore's Lee's.

Can Android Overtake the iPhone?

PC Magazine
By: Tim Bajarin

Five or six years ago, I had a number of meetings with some of the big PC manufacturers. I suggested they take a close like at Danger and the innovative interface used for the company's Hiptop handset. At the time, most cell phones had very simple e-mail interfaces. Very few even attempted to connect to the Internet. But Danger had a clear vision of what phone could become, creating what I would consider the granddaddy of today's smartphone interfaces.

By that point, it was becoming clear to some of us analysts that smartphones were actually small computers. If PC companies were going to stay ahead of the curve, they would have to add a handset to their line soon. At the time, I was very intrigued by Danger's interface. It was so well designed that it could be deployed on a TV, PC, smartphone, or just about any other digital device. Such a UI could help one of these companies deliver a similar experience across devices. And people would only have to learn to use the interface once.

Ironically, Microsoft ultimately purchased Danger. To date, the company has not employed this smart UI on any of its products. The genius behind Danger was a guy named Andy Rubin. He left the company before it was acquired by Microsoft, in order to begin working on a secret phone OS that would eventually get Google's attention. Google bought Rubin's small startup. The mobile OS eventually became Android, which, as you know, has since become the hottest OS in the smartphone space, having been adopted by dozens of handset vendors around the world.

I was reminded of Android's power while walking the CTIA show floor in Las Vegas. The show should have been called Android World. A good number of the handset companies I met with had some version of Android on their smartphones, and a number showed me new product behind the scenes that use the OS. I also saw at least five tablets (most behind the scenes) running Android that are set to come out in the next six months.

The most innovative products I saw at the show were based on Android. Take the Samsung Galaxy S, which runs the OS and sports a four inch AMOLED screen. It's the best screen that I have ever seen on a smartphone. Images on the phone are crisp and bright and are even clear out in the sunlight. Samsung won't say when it is coming to the US, but it could be one of the more important Android phones to launch this year.

The Motorola i1 is a new rugged and sleek push-to-talk handset that runs Android. At the press conference, Motorola let people play shuffleboard with the handset to show just how rugged it is. Kyocera also announced an Android handset—the ZIO. The phone has a beautiful 3.5 inch screen, 3.2 megapixel camera, and stereo Bluetooth. It will cost $250 unlocked.

If CTIA had a Best of Show award, it would have gone to Sprint's EVO 4G WiMax phone. The handset has a 4.3 inch screen, 1 GHz SnapDragon processor, 1GB of internal storage, WI-FI, HDMI out, and the ability to act as a WI-FI router for up to eight devices. It's a stunning phone that uses a version of Android that looks more like a Pocket PC OS than a cell phone OS.

Dell debuted the Mini-Tablet 5, the company's first Android tablet for the US. It has a five inch screen perfect for Web browsing. However, even though Dell says that the device will fit in your pocket, it's really not a smartphone. You wouldn't hold it up to year ear to talk. A Bluetooth headset makes more sense for conversations. The product is what I call a "tweener." It's not really a smartphone, and it's not really an iPad-like tablet. I'm not really sure who the audience will be on this one. On the other hand, the tablet has a really cool design and its light weight, compact design could be of interest to some users.

Android is steadily becoming the go-to OS for smartphones and tablets. It's even showing up on some set-top boxes and smart Blu-Ray players. But it's in the smartphone and tablet spaces that the mobile OS will have its greatest impact. Although Nokia and RIM were well represented and Microsoft and Palm each had booths at the show, most other major handset manufacturers like Samsung, HTC, and LG were in the Android camp. It's clear why many market research firms believe that Android will be the number one or two smartphone OS in the next two years.

It's also clear why Android is at the heart of the Apple/Google battle. Apple should be keeping at Windows Phone 7, sure, but it's Android that is likely to be the biggest threat to the iPhone OS in the near future. When Steve Jobs invited Google CEO Eric Schmidt to join Apple's board, he likely didn't expect Schmidt to go to school on Apple's strategy by launching its own iPhone challenger. No one Jobs is upset at Google.

Logical deduction from being able to solve inequalities

I was reading my lecture notes a few moment ago and I thought the logical deduction of the fact that since we are able to solve inequalities, then it also means we can solve equalities and negation.

Suppose we are able to solve the below two inequalities,
  1. α ≤ r
  2. β ≥ r
then, we have
  • α ≤ r ≤ β

With that, we should be able to solve r = α since we know α ≤ r ≤ α

  • r = α ≡ α ≤ r ≤ α

  • α < r < β ≡ α + 1 ≤ r ≤ β - 1

And also,
  • α ≠ r ≡ (L < r < α) ∪ (α < r < R)

Windows Live Messenger "You have 1 Invitation" Bug

Windows Live Messenger seems to have an annoying bug, indicating "You have 1 Invitation" but in fact there is really none.

A Microsoft MVP on Windows Live Messenger has confirmed in a forum that this is a known Windows Messenger bug and will be resolved in a later release. This is not a security flaw and so does not warrant a high enough priority.

Instead of waiting for a new release, the below method can be attempted to remove the annoying invitation alert.
  1. Close Windows Messenger (Make sure it is not running)
  2. Go to C:\Users\AppData\Local\Microsoft\Windows Live Contacts. Note that it is required to have "hidden files and folders" shown to browse the above location.
  3. Remove everything in the aforementioned location

Minister Mentor Lee Kwan Yew said Singaporeans are Champion Grumblers

An excerpt from the transcript of Minister Mentor Lee Kwan Yew's interview with Mark Jacobson from National Geographics on 6 July 2009 (For National Geographic Magazine Jan 2010 Edition)

Q: "Do you feel satisfied that that's moving along quite well? Or do you worry?"

Mr Lee: "I think for the next ten years, with this team in charge, it is going to be fine. Whether they will do well for the next 10-15 years depends on whether they get a younger team in place, well imbibed into the methods of the government, integrity, ability, and making decisions for the public good, and not for your personal benefit. That's all. It is difficult because it means sacrificing privacy and sacrificing pay. Now we solved the pay problem or semi-solved it by giving them 80 per cent of the average of six major salary earners."

Q: "Is that how you arrived at it?"

Mr Lee: "Yeah, but we are always lagging behind because whenever there's a downturn, we don’t give the rise. Whenever there's an upturn, the private sectors goes up, shoots up suddenly and we can't keep pace because the public says no, this is too much."

Q: "Well, when people are getting US$16 billion bonuses for bringing the country into the ground, it is hard to keep up."

Mr Lee: "I was once asked about the enormous, the best paid ministers in the world. I said you should look at the wives. The lowest-paid ministers have wives who are glittering with jewels and with big mansions."

Q: "So that means they are corrupt."

Mr Lee: "No, I didn’t say that."

Q: "That was pretty way to be said."

Mr Lee: "But it's true. So Singaporeans have to decide. Do you want to underpay a minister and you have the kind of shenanigans as you have in the British Parliament? You know they repair their homes in the country and in London and charge it to their account. Or you pay them a proper wage and said after that, look after everything. Nobody gets any special perks. That's your salary, you buy your car, you do what everything is yours. Official entertainment, you have got an expense account. Your secretary monitors it and audits channel clears it. So everything is above board and the public knows that. So whatever they grumble, they know that they are not being shortchanged."

Q: "There are grumbles but there are always grumbles."

Mr Lee: "There must be. Singaporeans are champion grumblers."

Q: "Thank you so much.

Skyrocketing COE prices does not equate lower public transport fares

With COE prices skyrocketing, fewer people will be buying cars. And as more COEs expire and more people taking up public transport, quality of transport will definitely drop. Will public transport fares move southwards months or years to come? I do not think so.

Let's see what the Public Transport Council (PTC) has to say this coming June when the next reviewal of public transport fares arrives.

Apple's New iPhone OS 4 License Blocks Flash

Given Steve Job's reluctant to allow iPhone to support Adobe Flash fully, I do not understand why so many people are still so crazy for the phone.

An excerpt from the new iPhone OS 4 License says:
Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited).

This updated iPhone Developer Program License Agreement in the iPhone 4.0 SDK specifically prohibit the development of apps using "an intermediary translation or compatibility layer or tool," which would include Adobe's Flash, Sun's Java, or Microsoft's Silverlight/Mono.

This news is a blow to Adobe, which has been working furiously to develop its Flash to iPhone cross compiler as the key new feature for Flash Professional in Creative Suite 5 (CS5). The upcoming CS5 would allow the Flash Professional application to export existing Flash content into a native iPhone application package that could be legitimately sold in the iTunes App Store because it was no longer Flash, and therefore no longer needed any sort of external runtime to play. The new iPhone 4.0 SDK license is now even more restrictive and effectively prohibit the new Adobe CS5's add-on.

Google Gmail Labs has unveiled two highly requested features.

Nested Labels. It is now possible to nest labels within a label, forming a hierarchical organisation. This is similar to folders and subfolders but the key difference is the new Gmail labels allow an email to be tagged by more than one labels.

Message Sneak Preview. With this feature turned on, it would be possible to preview messages to get a glimpse on what they contain without opening them. Simply do a right click on the message from Inbox (message list).

Why do Finland's schools get the best results?

In Finland, schools do not compete with one another and their philosophy basically surrounds trust. Teaching is a prestigious and recognised career in Finland and teachers are highly valued and regarded.

In a class, there will a second additional teacher who helps those who are weak in a particular subject. There is no such thing as streaming in Finland unlike Singapore and all pupils are all kept in the same classroom, regardless of their ability in that particular subject. From primary to secondary schooling, all students and teachers are together i.e. teachers and students know and understand one another and all grow together to avoid any potential disruption. No student is left behind.

The Finnish philosophy with education is that everyone has something to contribute and those who struggle in certain subjects should not be left behind.

The system's success is built on the idea of less can be more. There is an emphasis on relaxed schools, free from political prescriptions. This combination, they believe, means that no child is left behind.

The company core business is in the area of vegetable processing based in China. Given the fact that GIC has invested and the business is a first of the kind to be listed locally in Singapore, the stock should be stable.

I should be going for this one and hopefully I can get it.

Yet another reason why I just don't like Apple.

Astroturfing in the air : 'Poison' pen letters hit Sengkang

Seems like Astroturfing is in the air!

Even before the date for the next General Election has been announced, a poison pen letter has surfaced in Sengkang.

Written on a piece of A4-size paper in both English and Mandarin, it has been stuffed into the letter boxes of residents there, apparently since last week.

In it, the anonymous author accuses the People's Action Party (PAP) of being responsible for the high cost of living and the 7-per-cent GST, among other complaints.

Poorer by $115

Though I am poorer by $115 today after having given a farewell lunch treat to my colleagues, I felt good. The lunch was co-shared by a fellow colleague which means the cost of the lunch for a total of 19 people is $230. The Hong Kong style dim sum being served though good was still inferior as compared to Crystal Jade and those from Hong Kong.

I am going to be poorer by yet another $70++ for tomorrow's dinner buffet at Kuishin Bo.

HDB advised Sheng Siong to consider before making rental adjustment

The HDB said they have advised Sheng Siong to consider before making any rental or tenancy adjustments. This is after Sheng Siong 30 per cent increase in rental of stalls in their recent bought over of wet markets in areas located in Choa Chu Kang, Bukit Batok and Serangoon North.

HDB commented that Sheng Siong is a private company and thus has no rights to force them to do certain business decisions. I wonder what is the use of just merely say but then no action taken. HDB has also further assured vicinity's residents these wet markets will remain as wet markets and any conversion must come with their approval. Till date, approximately 10 per cent have decided not to carry on with their business due to the 30 per cent in rental fee, and should more leave, will Sheng Siong have a strong case to convert them into a new business setup?

After all, Sheng Siong is a private operator.

Toyota's Dilemma: Pay record fine or Fight the government at the cost of more bad publicity

Pay record fine or Fight the government at the cost of more bad publicity? This is going to be one of the toughest dilemma Toyota is going to face. The company has an April 19 deadline to accept or contest the penalty, and if they choose to pay the fine, it is going to be a record US$16.4 million fine. Paying the fine could be could be cast as an admission of wrongdoing but to fight against the government can result in bad publicity and long trials. The proposed fine of US$16.4 million is the most the government could levy, but further penalties are possible under continuing federal investigations. It is to note that Toyota is already flooded with hundreds of private lawsuits.

Interesting media release by Noble Group in response to Peabody's bid for Macarthur

Noble Group (N21.SI) has issued an SGX statement creatively entitled It’s all very simple, making fun of Peabody’s tortuous case for buying Macarthur.

I found the media release interesting and is worth publishing here.


We at Noble read with interest Peabody's long and convoluted defense of their "indicative offer" for Macarthur.


Their explanation of the merits of their deal went on for paragraph after paragraph and sure was hard to follow.

It reminds us a bit of Shakespeare in Hamlet, Act 3, Scene 2,

"Peabody doth protest too much, methinks."

They went on and on and on, but in fact, it is quite simple:

1. Take their cash if you don't believe in the future of coal. Keep in mind, if they weren't buying it cheap, even at 14 bucks a share, they wouldn't be doing it. We believe that coal is in a once in a multi-decade bull run. So do Peabody, which is why they are trying to get you to give them a great coal operation for their rapidly depreciating dollars.

2. If you believe in coal for the long-term, and want to stay in a company that intends to develop into the largest independent coal producer in Australia, vote for the Gloucester-Macarthur merger on Monday, April 12.

It really is that simple.

How to Calculate a Random Number from a Normal Distribution?

The NORMINV(probability, mean, standard_dev) function in Microsoft Excel returns the value x such that, with probability p, a normal random variable with mean mu and standard deviation sigma takes on a value less than or equal to x. Using RAND() function that generates random probabilities between 0 and 1, we can use the NORMINV function to calculate a random number from a normal distribution, using this formula:

=NORMINV(RAND(), mean, standard_dev)

However, Jerry W. Lewis, a former Excel MVP and a professional statistician, commented that using NORMINV(RANDINV()...) to generate Normal variates is not recommended in Excel XP or earlier. Excel 2003 or later yields acceptable result.

Jerry recommends the Box-Muller Transformation method instead. Using Box-Muller Transformation approach to calculate a random number from a normal distribution, the formula in Excel would be

Objectives of Secure and Fair Electronic Voting

First, only the eligible voters can vote and each voter can vote only once. The ballots of the eligible voters should be correctly accumulated in the tally. In addition, the ballot should be secret so that others cannot infer the intention of the voter. With ballot secrecy, the voter may feel free to express his or her intentions without fear of retribution. As the voted ballots lack physical protections such as the polling boxes in conventional voting methods, the results of the voting should be verifiable. Further, the voting cannot be disrupted by the voter regardless of whether or not he or she will be traced.

A tiring long weekend

The whole of Friday was spent working on CS5258 Assignment 2, reviewing an Information Security Policy, improving it, and writing a critique out of it. I am blessed to have two capable group members who are responsible and proactive enough to complete their given tasks, and sometimes doing more than required. Deadline of Apr 5 shouldn't be a problem at all.

On Saturday, most of my time was spent reading through and comparing a total of 5 research papers before finally selected the best for a literature review for my CS4236 Assignment 2. The next question is coming out with a decent practical solution to my problem - Secure Electronic Voting. This is an individual assignment due on Apr 10.

Time flies and today marks the last day of the long weekend. I better get started with my CS5322 Group Project else I will have nothing to show for this coming Tuesday's discussion. Time is equally tight for this and the deadline is less 2 weeks from now, which is Apr 15.

Other than the above 3 milestones, 1 quiz and 1 individual assignment, both for the sadistic CS5322 lecturer, await me.

Normal distribution

In probability theory and statistics, the normal distribution or Gaussian distribution is a continuous probability distribution that often gives a good description of data that cluster around the mean. The graph of the associated probability density function is bell-shaped, with a peak at the mean, and is known as the Gaussian function or bell curve.

Stacks of financial annual reports left untouched

Just when I commented receiving only one financial report in hardcopy format from Mapletree Logistics Trust, the rest arrived one after another.

So far, ST Engineering and CapitalMall Asia came in the form of a CD-ROM while Mapletree Logistics Trust, Cambridge Industrial Trust, Neptune Orient Lines and Parkway Holdings all came in as hardcopy and CD-ROM.

These financial reports remain piling on my table collecting dust.

Improved comment collapsing for Google Buzz posts

Any Google Buzz post can turn into a lively discussion. Sometimes these conversations can gather lots of new comments very quickly, turning them into "skyscraper" posts that can dominate your entire screen, especially if you don't check Buzz for a few days. We've heard from many of you that these big posts can be a lot to skim over.

Today, we’re making some changes to how comments get collapsed in Google Buzz. In the past, old comments were sometimes collapsed, but new comments (posted since your last visit to the Buzz tab) were always expanded. Now, if there are enough of them, new comments may be collapsed as well.

'Red Shirt' blood had HIV, Hepatitis B and Hepatitis C viruses

The Bangkok Metropolitan Administration (BMA) on Friday confirmed that some blood samples from the 'Red Shirt' activists, splashed as part of their blood-splashing activities last month, were contaminated with the HIV, Hepatitis B and Hepatitis C viruses. There can be a possible outbreak of diseases.

I personally find this action socially unethical. Clean and healthy blood could have been put to better use like donating them to someone who is in need of a blood transfusion.

Foxit Reader new release to patch critical vulnerability

A few days ago, PDF researcher Didier Stevens announced a "feature" that it is possible to execute arbitrary code out of PDF files. This feature becomes a "security vulnerability" on Foxit Reader because there is no warning dialog when an embedded executable runs.

In response to this, Foxit quickly released Foxit Reader to show a warning dialog whenever an embedded executable is to run.

What makes a procession?

A group of five in whatever formation may not create the impression of a group 'in a compact body marching in close formation', but can nonetheless be a procession.

Singapore to raise electricity tariffs again from this April onwards

Despite continuing profit by the Singapore Power, the power generation companies and suppliers, electricity tariffs is to be raised again from this April onwards.

The Online Citizen, an online site based in Singapore, published an article with many questions, hoping to get answered so as to justify the increase in electricity tariffs.

Singapore was ranked second among 21 cities, after London, for raising electricity tariffs most, since 2005. This is something not to be proud of.

Why is the electricity tariff up again on 1 April, despite the decline in real wages last year, about 60,000 residents still unemployed as of December, and Singapore is just coming out of its worst recession?
