Programming language trends – 2012 review | Jobs Tractor – PHP and Java up on top with over 12k jobs each and very little distance between them. Objective C is next up but below 10k jobs at around 9k in total. As we get to number 4 (SQL) we're already close to 5k which shows just how much Java and PHP are dominating the stats. Android skills came in at number 5 with close to half the number of jobs which had been listed for Objective C
nealford.com • Why Everyone (Eventually) Hates (or Leaves) Maven – Maven is perfect for starting new projects: it ensures consistency and provides a huge bang for the buck in terms of already existing functionality. But because something starts strong doesn’t mean that it scales well (in fact, almost always the opposite is true). The real trick is to use Maven until the day it starts fighting you, then find an alternative

Blitz4j efficiently generates logs within a massively concurrent and heavy traffic environment while consuming fewer resources than other, more traditional logging technologies. It achieves this by overriding sections of log4j’s code where synchronization and deadlocks may occur.
How People Change – NYTimes.com – It’s a lousy leadership model. Don’t try to bludgeon bad behavior. Change the underlying context. Change the behavior triggers. Displace bad behavior with different good behavior. Be oblique. Redirect.
How Amazon Followed Google Into the World of Secret Servers – “It will be interesting to see, over the next 10 years or so, how successful the traditional server vendors will be competing against that kind of server capacity,” Pinkham says. “Once developers realize they can use this much cheaper, homogenous infrastructure, the power may shift toward the folks who build the cheapest, simplest hardware.”

Obama Wins: How Chicago’s Data-Driven Campaign Triumphed | TIME.com – That data-driven decisionmaking played a huge role in creating a second term for the 44th President and will be one of the more closely studied elements of the 2012 cycle. It’s another sign that the role of the campaign pros in Washington who make decisions on hunches and experience is rapidly dwindling, being replaced by the work of quants and computer coders who can crack massive data sets for insight. As one official put it, the time of “guys sitting in a back room smoking cigars, saying ‘We always buy 60 Minutes’” is over. In politics, the era of big data has arrived.
