iOS Development: Proper Use of initWithNibName:bundle: Affects UITableViewController
July 6, 2011 by Leave a Comment
I think this post will be useful to someone new to the iOS development. One of the most important and commonly used classes in Cocoa is UIViewController. Creating any non-trivial application will involve subclass and creating your own view controller. There are a lot of topics and tutorials elsewhere, so I’m not going to repeat [...]
Programming iOS 4: Making Simple Ideas Complicated?
June 30, 2011 by 2 Comments
I have done a bit of iOS development lately. While trying to get myself familiarized with the new platform, I came across this book titled “Programming iOS 4″. I skimmed through some sections and found this paragraph: You should not use a view controller in any other way. It is not, for example, appropriate to [...]
Scripted Debug Using GDB To Find Memory Leak
June 29, 2011 by 3 Comments
I recently ran into some hard to find memory leaks. The program only runs on Linux. The memory leaks are detected using a custom memory allocator (using an atomic counter for allocation/deallocation size).

Finally! After a few weeks of waiting in line then gave up to ordering online then gave up routine, I have gotten my own iPad 2! It’s a gift from my wife who understands my nerdiness, unlike this person’s wife. After playing with it for a few days I would like to share some unbiased opinions. I [...]
LLVM, Clang, and (no) Auto Vectorization
March 5, 2011 by 2 Comments
A few days looking into LLVM + Clang, I really liked how they are set up and how they work. I played with the IR code and JIT a little bit, then I realized that Clang and LLVM don’t support auto vectorization (as of current release 2.8).
