  Some thoughts about Facebook native app

On Techcrunch Disrupt last month, Facebook CEO Mark Zuckerberg's remarks about their mobile app sparked a denunciation against Web App. HTML 5 seems to have become the bottleneck of poor experience of all related mobile applications. From the user perspective, Facebook native iOS App rates from the 1.5 star to four star now; since the introduction of new native app, the user usage is doubled. It's not easy to have a huge rise of user usage for such a big app like Facebook. Especially consid...

  Testing like the TSA

When developers first discover the wonders of test-driven development, it’s like gaining entrance to a new and better world with less stress and insecurity. It truly is a wonderful experience well worth celebrating. But internalizing the benefits of testing is only the first step to enlightenment. Knowing what not to test is the harder part of the lesson. While as a beginner you shouldn’t worry much about what not to test on day one, you better start picking it up by day t...

  Add Sublime Text to your context menu on right click

When opening a text file, you may be used to right click on the file to be opened and then choose the application which can open the file from the context menu.

  9 quotes that stayed with me as a developer

I find quotes inspiring, motivating or sometimes just thought provoking, so here's some of my favourites from over the years. Sometimes reading a book can have a real influence on how you write code, or how you approach a problem. Sometimes a simple quote  is enough to make me question the way I look at the code I'm writing. Or often I sit in awe about someone's so well distilled what I've known internally for ages but have never been able to enunciate.   "Design is finding t...

  The latest on Java-on-Java: the Oracle experiment that is gaining momentum

What is Project Metropolis? The not so hush-hush Project Metropolis is all set to implement Java on itself – popularly known in the developer community as Java-on-Java. Oracle has released updates on its progress, and they are very encouraging. The project will focus on building a JIT (just in time) compiler that is written in Java.

  "Programmer" is an Overgeneralization

"Beware of bugs in the above code; I have only proved it correct, not tried it." - Donald Knuth Earlier today, I came across a post during a google-fu session that claimed that no one should use the C++ standard library function make_heap, because almost nobody uses it correctly. I immediately started mentally ranting about how utterly ridiculous this claim is, because anyone whose gone to a basic algorithm class would know how to properly use make_heap. Then I started thinking about all the ...

  Use downcase! with caution in Ruby

Ruby provides ! to change state of some object in place. Hence if you see some functions have ! appended, it means the state of the caller of the function is expected to be changed. This is a very interesting Ruby feature. But sometimes one should be cautious when using this kind of functions because you would get unexpected behavior if using improperly. Let's take an example of String#downcase!. According to the documentation. Downcases the contents of str, returning nil if...
