Adidas fails to deliver promised sponsorship in Sundown marathon 2010 contest

Winners(not) from Sundown Marathon 2010 – Get Spotted Contest

I was 1 of 25 runners that “won” the “Adidas Get Spotted Get Sponsored Contest” in Sundown marathon 2010 held in Singapore last year.

http://www.sundownmarathon.com/index.php?mact=News,cntnt01,detail,0&cntnt01articleid=35&cntnt01returnid=78

Adidas then sent us a congrats email, which indicated we can start redeeming on Jan 2010, via this email - Running.sg@adidas.com

However, it is now already mid feb and no news from Adidas. Despite countless emails to Running.sg@adidas.com, i have not gotten a single response from them.

Adidas is really disappointing. Never attempt to deliver empty promises to your customers. Creating a contest without delivering the prizes to the winners is blatant cheating, in my honest opinion.

Maven Dependencies for Eclipse Helio WTP

Kenny Lee — Tue, 23 Nov 2010 03:31:44 +0000

So you’ve been wondering why doesn’t your WTP project’s maven dependencies get copied over to the directory where eclipse stores your web project files.

Mine is C:\Documents and Settings\kenny\workspace\helios\.metadata\.plugins\org.eclipse.wst.server.core\tmp0

For that to happen, follow these steps:

Install m2e-extras.
Right click on your web project and choose “Properties”->”Deployment Assembly”->”Add”.
Select “Java Build Path Entries”->”Next”.
Select “Maven Dependencies”->”Finish”.
Maven dependencies for eclipse
Clean your project and you should be done!

Debuging java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener in Eclipse, tomcat, maven

Kenny Lee — Thu, 28 Jan 2010 02:41:03 +0000

If you’re developing a spring-enabled web application using the combination of Eclipse, Tomcat and Maven. You might encounter the following error when you try to start tomcat within eclipse.

My 7 fav free apps for Apple’s iTouch

Kenny Lee — Thu, 11 Sep 2008 18:14:24 +0000

Recently got a free iTouch after finally purchasing my Mac Book Pro under the “Back To School” Promo which will end on 16 Sep 08.

So i checked out the app store for any free apps/games and noticed i needed to purchase the iPhone upgrade for iTouch at USD 9.95. Well, didn’t came across as too expensive, so purchased i did and downloaded the following FREE apps/games.

Twitterific (Category: Social Networking). I twit some garbage collections here by the way.
Airport Status (Category: Travel) – To check airport statuses.
Talking Spanish, Italian, French (Category: Travel) – In case i sign for Real Madrid or AC Milan.
GPS Tracker (Category: Navigation) – Well, i am an infantry company scout during reservist. So…
Free Hangman (Category: Games(Free) ) – The only worth-while free game.
Remote Desktop Lite (Category: Business) – Provider access to a PC running, woohoo, Windows XP.
Checklist (Category: Productivity) – Think “Get Things Done(GTD)”

Now my iTouch is packed with apps, the default ones + the downloaded ones, and they flows to 2 screens (1 screen can only contain 16 apps). So i placed all the important apps on the 1st screen, naturally.

Worth the USD 10 bucks? Probably. Do note that the installation took 30 minutes and just a handful of clicks, the rest are magic. Bonito!(Spanish) Buono!(Italian) Beau!(French)

Anyone has other good recommendations? Non-Free or Free.

Combining Agile Methodologies – XP and Scrum

Kenny Lee — Wed, 10 Sep 2008 19:12:28 +0000

Since XP is more focused on development practices(engineering), while Scrum more towards project organization(management), it seems possible to combine this 2 methodologies.

Having experience both agile methodologies separately, here’s my take on the must-haves.

Planning
- Daily Standup(XP/Scrum) – What you done yesterday, going to do today, obstacles if any.
- Break down requirements into user stories (XP), then put them into a product backlog using excel or web tools like acunote (Scrum)
- Physical task-board for easy and quick viewing of sprint tasks
Coding
- Test Driven Development(TDD) by writing the unit tests first. (XP/Scrum)
- No one owns any particular code. All code can be changed by anyone. And codes are integrated often. Thus a source control system(CVS, SVN, VSS, etc) have to be in place. (XP)
Testing
- All code must be tested before putting to production. (XP)
- When bugs are found, new unit tests are written to guard against repeats. (XP)
Releasing
- Have a demo before release and review after release. (Scrum)
- Release early, release often as they say. (XP). Preferably keep a sprint within weeks rather than months.

Interesting Differences.

XP prefers having no overtime anytime, anyday, while scrum prefers no rest within a sprint, which probably means no off days and leave, unless urgent, for a good 3-4 weeks.

Summary
Majority of the coding and testing rules come from XP, while planning rules come from SCRUM. The key is to keep the rules flexible. Sprint reviews after each sprint allows you to better fine-tune your rules, based on team strength/weakness or project nature. Well, as long as they work for you.

Codepad. Run code snippets online.

Kenny Lee — Wed, 20 Aug 2008 05:27:07 +0000

Just discovered an online tool that allows me to run code snippets in many languages such as php, python, ruby, haskell, lua and many else. (See all http://codepad.org). Sure you can use irb for ruby, etc, provide you’ve install them on your box.

The results of code run are also available via a URL (Check out my ruby snippet. )

Well if someone doubts your code and is lazy to go over your desk when you argue that it works on your machine(yeah, it “always works” locally). Just send them that code result URL !

Cherokee. Faster than Apache / Lighttpd ?

Kenny Lee — Wed, 20 Aug 2008 05:10:36 +0000

Seems so, based on their benchmark.

But then again, it’s their own benchmark.

Some seemingly neutral ones:

- Cherokee Vs Lighttpd from riklaunim

- Cherokee Vs Nginx from riklaunim

Battle of the Property Search Engines – PropertyGuru vs iProperty

Kenny Lee — Fri, 15 Aug 2008 04:50:50 +0000

User Friendliness – Age of Web 2.0

Seems that it’s harder to choose the districts from iProperty.com.sg as users have to reference the map to know the district they are interested in. Propertyguru.com.sg does a better job at that.

Do you prefer to remember numbers or words? Ala, http://72.14.207.104/ or http://google.com ?
