I started making this font since July, 2007. After a long time tweaking and testing, the first public version was released in Jan, 2008. The original purpose to design this font is to create a monospaced font which width is exactly 50% of height. So it can display with raster Chinese fonts (only in 12x12, 14x14 and 16x16) well. But after I finished it, I found it looks not bad and some western developers might like it. So I added the European characters and made this web page in English. But if you want to know the full story about this font, you should read the Chinese version ;)
Because I'm a C/C++ developer, so this font is especially optimized for C-like programming languages. It has ultra black ",.:;" to help you find the end of statements easily. And it is a REAL programmer font, means even you are using an old fashioned text editor without syntax highlighting, you would never made mistakes on identifying "0oO" or "Il1".
Another funny feature is the "invisible character" display support. If there were some invisible characters in your text, with regular fonts you will see something like this (using the Fixedsys font):
