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 […]
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 […]
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). In single thread mode, the program terminated without leaking, but running in multithread mode resulted in 1.7 to 4 KB of leaked […]
I haven’t really done much web development in the last 8+ years or so, and my knowledge in that area has been mostly outdated. I have some ideas of a data centric web site with interactive data visualization and the question is what tool do I use to implement this idea? To educate myself, I […]
In a recent coding review a coworker pointed out in my code that modifying a STL list might invalidate the iterators pointing to the elements in the list. That’s a good observation. I know STL map will not invalidate iterators when elements are inserted or erased from the container. But for STL list, I can’t […]
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 […]
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).
It’s surprisingly easy. First, I’d ignore the instruction on LLVM’s page, and rather follow the instruction on Clang’s project page, which is much more concise and will build both LLVM and Clang.
I’m working on a project where I need to dump out object data for both debugging purpose as well as a way to store them persistently. My initial implementation which overloads C++ iostream for each of the objects proven to be inadequate when the amount of data I’m writing out become larger and more complex. […]
