Get back to hacking!

Russ Magee was the first of many of you to write in about Robert Cringely's analysis of the Halloween I document. He thinks the OpenSource community has no cause for concern, and he reminds us to stay focussed on Linux, not Microsoft. Karsten M. Self wrote "The article Art of War by Varian and Carl Shapiro is a good introduction to the basic strategies involved in a standards war. The book Rules by the same authors is a very good read with a lot ideas pertinent to the current debate.". However Ben Woodard writes "I was talking to the Access tech support people here at Cisco about Halloween and how MS is planning to use embrace and extend, Em&Ex, to capture the market. They told me how Microsoft has a broken version of CHAP negotiation in the PPP protocol and if you want CHAP to really work you must use Microsoft's proprietary version of CHAP. It got me wondering if other people know about places where Microsoft has used Em&Ex but it is burried so deep in the protocols that most people don't know it exists. It would be interesting to try to compile a list of these little known incidents of Em&Ex. " Obviously it is impossible to know whether Ben's example is an example of flawed testing or real intent to break CHAP, but were serious evaluations of OS's to include standards-compliance tests, an interesting picture might emerge. Not only are standards an issue, but so are patents. So far, Linux has been lucky: many Unix patents have elapsed. Patents are something to mull over, while hacking.
