• MapReduce at Rackspace - OK it is not MapReduce (as beloved by Stonebraker et al) but its open source breathen Hadoop. Original link (and more info) at How Rackspace Now Uses MapReduce and Hadoop to Query Terabytes of Data.
• MapReduce II - more installments.

• London Erlang Meeting - “How do you test large systems written in Erlang?” on Monday (I presume) Jan 21.
• Map Reduce a major step back. Michael Stonebraker and David J. DeWitt let forth on why they dislike Google’s MapReduce infrastructure and how it is poor relation to standard relational database technology.
• Relational Database Experts Jump The MapReduce Shark - a reply to Stonebraker and DeWitt that I pretty broadly agree with.
• MapReducing 20 petabytes per day - Greg Linden commenting on the recent paper “MapReduce: Simplified Data Processing on Large Clusters” by Jeff Dean and Sanjay Ghemawat.

Erlang design patterns/best practice?

I am struggling to find any decent links to design patterns, best practice or good, basic architectural principles that you should use in building Erlang apps. Anyone know of any?

• Computational Advertising talk on Thursday Jan 10 (via Greg)
• “Why did we create Erlang“
• Google has a new competitor (…sort of).
• Why Events Are A Bad Idea (for high-concurrency servers) - an oldie but good to keep you on your toes. I have been seduced by event driven systems for a long time. I thought SEDA was just wonderful when I first read about it. Message passing systems seem so much nicer to me - even if a little too esoteric for most people sometimes. However it is important to remember that threads can work well (just that it seems that most threading implementations are not up to scratch. Shame).

McKnight Principles

The McKnight Principles:

“As our business grows, it becomes increasingly necessary to delegate responsibility and to encourage men and women to exercise their initiative. This requires considerable tolerance. Those men and women, to whom we delegate authority and responsibility, if they are good people, are going to want to do their jobs in their own way.

“Mistakes will be made. But if a person is essentially right, the mistakes he or she makes are not as serious in the long run as the mistakes management will make if it undertakes to tell those in authority exactly how they must do their jobs.

“Management that is destructively critical when mistakes are made kills initiative. And it’s essential that we have many people with initiative if we are to continue to grow.”
