Xcode 4 has a lot of cool new features. One of my favorites is it’s ability to tell you when you introduced a bug in your code; the feature is similar to a spell check found in a word processor. Usually, these cool tools are only available for Objective-C, but because of LLVM, this feature … Read more
If you need to set a boost shared_ptr to NULL, then you can do it like this: boost::shared_ptr(); So, if you have a function that returns a boost shared_ptr and you want to pass NULL to represent either an error state or a not-found state, you can do this: #include typedef boost::shared_ptr OohClassPtr; typedef std::map< ...

Right now I’m dealing with some code of mine that isn’t working on a Microsoft product. I got a webcam, a Microsoft Life Cam VX1000, that doesn’t want to work with DirectX. It’s weird. A Microsoft product that doesn’t want to work with a Microsoft SDK. I see on the web though that there are … Read more
I love reading code like this: int IAmGoingToReturnAnInt ( int* gimmeSomeData ) { int munchMunch = *gimmeSomeData; ++munchMunch; // Developer note: FU } Okay, the last developer note doesn’t really exist, but you would think that this function would return an integer. I mean, come on! Give me something!
Recently, I was looking at a bug report for an error that would only happen on one operating system. When I looked at the code… I had wondered why no one called this one out: char buffer[128] = {0}; // Some code here memcpy ( buffer, another_buffer, 128 ); // Some more code free (buffer); … Read more
I’m a fan of Herb Sutter’s books and articles. Now that he is coming out with a new book, “Effective Concurrency”, I can’t wait to get my hands on it.
A programming language does not enforce rules. It just gives you the means to tell a computer how to do something. In my previous job I saw how SQL was being mis-used and how there was a lack of design used in implementing certain databases. The language doesn’t guide you to creating good databases; this … Read more
I had a weird thing happen where if I create a TCHAR variable[MAX_PATH] and populate that using any Win32 function, then take that variable and memcpy it into a const char * that has been new’d, I get a HEAP corruption message when I call delete[] on the const char *. Now the funny thing … Read more
I read this and said to myself, this is so true. Thinking about this, if you don’t take the time to think about the comments, there is a good chance that the code below/next to/above the comments wasn’t well thought out either.
I’m surprised what people find interesting on my website. The most popular post is actually the Haversine formula page. Thinking about it, that whole process was a real pain in the butt to implement, so I can see that if someone else had to do it, that I could actually save them some time and … Read more
