Tim teaches at the University of Canterbury in Christchurch, and is Deputy Head of the Computer Science and Software Engineering department. I got a chance to ask him about his work in data compression as well as one of his new areas of interest, Computer Science education.]]> http://marknelson.us/2012/01/21/a-visit-with-tim-bell/feed/ 0 http://marknelson.us/2011/06/14/sapir-whorf-to-dijkstra-to-torvalds-language-bigotry-in-our-time/ http://marknelson.us/2011/06/14/sapir-whorf-to-dijkstra-to-torvalds-language-bigotry-in-our-time/#comments Tue, 14 Jun 2011 20:29:09 +0000 Mark Nelson http://marknelson.us/?p=439 Back in the day the Sapir-Whorf hypothesis was all the rage in the study of linguistics. With apologies to those who actually work in the field, I’ll crudely summarize it as the idea that the language you speak both constrains and influences how you think. The idea says that if your language only has one [...]]]> http://marknelson.us/2011/06/14/sapir-whorf-to-dijkstra-to-torvalds-language-bigotry-in-our-time/feed/ 2 http://marknelson.us/2011/02/08/ken-olsen-rip/ http://marknelson.us/2011/02/08/ken-olsen-rip/#comments Tue, 08 Feb 2011 14:21:16 +0000 Mark Nelson http://marknelson.us/?p=297 Photo by Nick Richards Ken Olsen, founder of Digital Equipment Corporation, died Sunday, February 6 at the age of 84. Looking back on the amazing arc of Ken Olsen’s life brings home an important point about the pace of change in the technology business.

It seems that Vinay dropped the news at the start of this week that he had proven that P does not equal NP. In short, this proof [...]]]> http://marknelson.us/2010/08/10/p-%e2%89%a0-np/feed/ 0 http://marknelson.us/2008/05/21/corley/ http://marknelson.us/2008/05/21/corley/#comments Wed, 21 May 2008 19:55:21 +0000 Mark Nelson http://marknelson.us/2008/05/21/corley/ Yes, another middle manager in my organization has decided to part ways with my employer, Cisco Systems, Inc. Dave Corley has been a key part of Cisco since he was acquired along with the rest of Selsius in 1998.

Technology continues to improve, and there are certainly lots of good reasons for a device like Amazon’s Kindle to be the leading edge of a major wave of adoption.

Richard was never in the business of self-promotion – had he been, he could have been a household name among the cognoscenti. But Richard didn’t spend his time talking to the press, speaking at conferences, or teeing up with the titans of industry.

Personally, I think Johnson is pretty close to the mark on this one, but I will add one caveat.
