A Nice Break

by in CodeSOD on

Once upon a time, HTML had tags like <marquee>, which scrolled text across your page, and when combined with animated GIF backgrounds basically defined the Geocities aesthetic.

Now, in Java, the obvious answer would be to use the equalsIgnoresCase String member function. if (value.equalsIgnoresCase("true"))…. I mean, obvious to you or me, anyway.

Capitalizing on Memories

by in CodeSOD on

Gavin inherited some "very old" C code, originally developed for old Windows systems. The code is loaded with a number of reinvented wheels.

For example, they needed to do a case insensitive string comparison. Now, instead of using stricmp, the case insensitive string comparison, they wrote this:
