Abstract: Stuxnet, a sophisticated virus that damaged Iran's nuclear capability, should be an eye openerfor the world. We can choose to LEARN something very narrow (how to combat the Stuxnet virus) or wecan choose to focus on the larger goal of thwarting the next type of creative cyber attack. Unfortunately,critical industrial infrastructure is not currently designed with security as a key goal, leaving open multipleavenues for an educated and funded attacker to create massive problems. This tutorial outlines somebasic concepts that engineers and product definers should consider to make sure their new projects stayahead of future threats.

CBC下写的串口编程，API函数实例 I wish this site had been around when I was trying to figure out how to make serial communications work in Windows95. I, like many programmers, was hit with the double-whammy of having to LEARN Windows programming and Win95 serial comm programming at the same time. I found both tasks confusing at best. It was particularly frustrating because I had, over the years, written so much stuff (including lots of serial comm software) for the DOS environment and numerous embedded applications. Interrupt driven serial comm, DMA transfer serial comm, TSR serial comm, C, assembler, various processors... you name it, it had written it. Yet, everything I knew seemed upside-down in the message-driven-callback world of Windows.
