You Are Just One Click Away to Spend Those Dollars

2011-12-11T11:44:00.201+08:00

It's been years since the last time working on some shopping related web applications that I forgot the main angle behind the design of those applications is to make it as easy as possible for the customers to spend their money. The idea behind online shopping business is that it's so easy that as long as we have a credit card (or credit card numbers), we can order whatever we want. So last time

Toyota Commercial - Jean Reno as Doraemon

2011-12-10T07:00:00.000+08:00

A bit OOT but Doraemon is my childhood favorite cartoon, so here we go, 3 parts, with English translation. Shizuka: What are we going to be when we're adults? Suneo: A rich man! Takeshi: I want to be a singer. Shizuka: How about Nobita? Nobita: It seems like I don't have any dream. Doraemon: What? You don't have any dream at all? Nobita: I want to go out with Sizhuka with a car!!!! Takeshi:

Book Review: Your Money - The Missing Manuals

2011-10-01T19:24:00.002+08:00

Right after reading the first chapter of Your Money: The Missing Manual, you might think that it mainly and only talks about frugality. You are right, it's all about frugality. But there's actually much more inside of it. I like how the author explains about the relationship between money and us. And also the way he tells things by using himself as an example. I actually skipped a few chapters

Debian Squeeze on Macbook Pro (Part III)

2011-09-25T12:51:00.000+08:00

This might be the last part of Debian Squeeze installation story. In this part I'm going to describe about what I did for backup. At first, to backup the entire debian system, we can use "dd". The command is like this: dd if=/dev/sda4 of=/path/to/backup-`date +%s`.img To restore, boot from some place else (live CD or the other OS) and then run: dd if=/path/to/backup.img of=/dev/sda4 Here

Debian Squeeze on Macbook Pro (Part II)

2011-09-11T01:12:00.003+08:00

So, this is what I did to make wifi works on Macbook. First, I had to connect to the Internet by using cable. Thanks God our house has the cable (confirmed with my housemate that the cable is dedicated to the people who needs to do weird things LoL). Below are the steps to enable connection via cable: Edit /etc/hosts, add newname so it become something like this: 127.0.1.1 debbie newname Set

Installing Debian Squeeze on Macbook Pro 13" (late 2010)

2011-09-09T13:33:00.000+08:00

Shrinking MAC OS partition Is almost impossible. Some people reported that DiskUtility hanged up in the middle of the process. For me, I ended up reformat the entire disk, and then re-install MAC OS on a small newly created partition (29GB), and left the rest as "FREE SPACE". Installing rEFIt Is perhaps the simplest task among all. rEFIt can be downloaded from: http://refit.sourceforge.net/

XPath

2011-08-03T23:11:00.000+08:00

XPath is used to navigate through elements and attributes in an XML document. Since HTML is basically an XML document, XPath can be useful in developing an automation test, web crawler, and perhaps an advanced XML parsing application. Example of XPath syntax: //input[@type="hidden"] this syntax will return all inputs of which type are "hidden" //input[@type="hidden"][@name="input_name"] this

Python Learning Journal (Part II - Preparing for Mechanize)

2011-07-23T22:32:00.001+08:00

To get familiar with Python syntax, I'll start with a play-around with web crawler scripts. I'll be using Mechanize, a supposedly stateful programmatic web browsing module. For introduction, I'll try to write a script to list out recent torrents from thepiratebay.org/recent. And later I'll proceed with a script to retrieve and then summarize flight tickets price from www.airasia.com. Input

Glomelurus.com: Short Story about Custom Domain Name

2011-07-23T14:27:00.001+08:00

I have finally subscribed a domain for this blog, triggered by an ads-tweet from my ex-colleague about hosting and domain name. First name came to mind is momotaro.com. I have been naming almost all of my computers I've ever used with this name. And then the domain has been taken (of course), since it's a hero name of a very famous Japanese classic story. But actually they are giving it up (not

Python Learning Journal (Part I - Foreword)

2011-07-15T13:08:00.004+08:00

Learning from past experiences and evidences, there is always a death point for everything when it comes to technology, especially IT. So it is always a good thing to try out something different, prepare yourself for that one day when you need to make that changes.I have been sticking myself to Java for at least 4 years (I started as a Delphi fans - the legendarily popular desktop programming

Sexism in IT Career

2011-07-09T14:03:00.007+08:00

It has never come to my mind to write this blog entry until I saw a Python workshop advertisement which is "specially designed" for ladies. I don't know if it represents sexism, but the first thing that passed in my mind is: why would women need a specially design workshop in the first place? Is it based on the assumption that women don't excel men in logic, that is why they need a separate

Building an Automated Test Script with RFT without Recording

2011-01-22T13:38:00.000+08:00

Some times ago, I wrote an entry about Automated Test. Until now, I still agree that a good automated test project, should be written without recording anything at all. I don't know why those automated test tools provide "recording" function. I don't think recorded automated scripts will be useful enough to support software development, since UI will always change, and some day you'll always get

Eclipse Plugins - KBS File Colored Editor plus CSV Colored Editor

2010-07-02T13:21:00.001+08:00

So I'm in this new company working with a framework called Selectica which is mainly dealing with KBS files. I wonder why everybody's eyes are so great looking at those plain Textpad screens without any color at all. So I managed to get one, by searching around on the Internet and turns out that this framework is such unpopular that nobody cares to create a colored editor. Finally I came to this

This code will always throw ConcurrentModificationException:for (Person person: group) { group.remove(person);}Because:You cannot remove an object from a collection while iterating through it.To solve this problem, use the clear() method to remove all objects of a collection.

Single Entry Point and Single Exit Point

2009-11-27T22:07:00.000+08:00

I don't agree with "single exit point" and so did I practically never apply it.Glad to find an entry on this website:http://stackoverflow.com/questions/1701686/why-should-methods-have-a-single-entry-and-exit-pointsIt said that:This advice is outdated and bad for code pratice because it will lead to temporary variable which is hard to maintain. To me, temporary variables smell bad a lot rather

Implement Paging for Data Display

2009-10-25T22:59:00.000+08:00

Almost every application need the feature of paging, whether it's web application or desktop application. Whenever you want to display some data to the user, there is no way that you display the entire set of the data to the user. Imagine that you have 1 million data on the DB, it would be inefficient either time nor resources. Especially if the application is a public website, the server might

How to Set JVM Proxy Setting Without Touching the Code

Simulation Game: Sim Tower

2009-09-06T12:03:00.000+08:00

So, last week I meet a friend and discovered that we were playing the same game on our childhood. I don't remember exactly when I started playing this game but I'm pretty sure that it was at elementary school because we played with Windows 3.1. At that time there was no Internet and my brother kind of copied the game from his friend who bought it from somewhere (maybe?). I had a nice childhood
