Today, I'm not writing anything new. Instead, I'm referring you to the series of articles by Ruediger Asche starting with Windows NT Security in Theory and Practice. These articles are quite old but the principles are still sound. Just bear in mind that the newer stuff won't be covered.
A common feature for many applications is to record their screen location when they shut down and reopen at that location when relaunched. If implemented naively, a program merely restores from its previous position unconditionally. You run into usability problems with this naive implementation. If a user runs two copies of your program, the two w...
In the operating systems group, we have to take a holistic view of performance. The goal is to get the entire system running faster, balancing applications against each other for the greater good. Applications, on the other hand, tend to have a selfish view of performance: "I will do everything possible to make myself run faster. The impact on th...
Remember that there are typically two 8-bit code pages active, the so-called "ANSI" code page and the so-called "OEM" code page. GUI programs usually use the ANSI code page for 8-bit files (though utf-8 is becoming more popular lately), whereas console programs usually use the OEM code page. This means, for example, when you open an 8-bit text fil...
It seems that when people notice that the Internet Explorer rendering engine doesn't use HWNDs for screen elements, they think that Internet Explorer is somehow "cheating" and doing something "undocumented" and has an "unfair advantage". Nevermind that windowless controls have been around since 1996. They aren't magic. Mind you, they're a lot of ...
In a previous life, I wrote database software. A customer complained that one of their reports was taking an unacceptably long amount of time to generate, and I was asked to take a look at it even though it wasn't my account. The report was a vacation-days report, listing the number of vacation days taken and available for each employee. Vacati...
The CMD.EXE batch language can be awfully cryptic, but for those who miss the richness of command lines like or bursts of line noise masquerading as a pipeline of "find", "sed", and "awk" processes, Microsoft Windows Services for Unix is available for free download.

It appears that some people interpreted the title of one of my rants from many months ago, "Cleaner, more elegant, and wrong", to be a reference to exceptions in general. (See bibliography reference [35]; observe that the citer even changed the title of my article for me!) The title of the article was a reference to a specific code snippet tha...
I try not to rant, but it happens sometimes. This time, I'm ranting on purpose: to complain about macro-izing flow control. No two people use the same macros, and when you see code that uses them you have to go dig through header files to figure out what they do. This is particularly gruesome when you're trying to debug a problem with some cod...
