The State of Ruby VMs — Ruby Renaissance 89

Posted by Soulskill
from the take-your-pick dept.
igrigorik writes "In the short span of just a couple of years, the Ruby VM space has evolved to more than just a handful of choices: MRI, JRuby, IronRuby, MacRuby, Rubinius, MagLev, REE and BlueRuby. Four of these VMs will hit 1.0 status in the upcoming year and will open up entirely new possibilities for the language — Mac apps via MacRuby, Ruby in the browser via Silverlight, object persistence via Smalltalk VM, and so forth. This article takes a detailed look at the past year, the progress of each project, and where the community is heading. It's an exciting time to be a Rubyist."

Slatterz writes "Come next week, Microsoft will be in the unusual position of no longer offering mainstream support for its most widely used product. Windows XP will pass another milestone next week on the road to retirement when mainstream support ends on 14 April 2009, over seven years after the OS originally shipped. While the company said that it will continue to provide free security fixes for XP until 2014, any future bugs found in the platform will not be fixed unless customers pay. Windows XP accounts for about 63 percent of all Internet-connected computers, according to March 2009 statistics from Hitslink, while Windows Vista makes up about 24 percent."

phantomfive worries about a report in the Wall Street Journal ("Makes me want to move to the country and dig a well") that in recent years a number of cyber attacks against US infrastructure have been launched over the Internet: "Cyberspies have penetrated the US electrical grid and left behind software programs that could be used to disrupt the system, according to current and former national-security officials. The spies came from China, Russia, and other countries, these officials said, and were believed to be on a mission to navigate the US electrical system and its controls. The intruders haven't sought to damage the power grid or other key infrastructure, but officials warned they could try during a crisis or war."
