Added Linux support to the TSMBIOS Project
The Road to Delphi

Legacy Code: Scoping
Rob's Technology Corner
– Hey when I change X why does it break Y when they "should" be completely unrelated. It's a common problem in development where changing one bit of code has unintended side effects on a different section of code. Proper varible scoping can help reduce these errors. Unit ...
