While I don't feel buffer overflows are something to ignore, from what I see the developer never actually said "unexploitable."

From the "skeptical glibc developer" link:

Hmm. How likely is that? It overflows in to malloc metadata, and the
glibc malloc hardening should catch that these days.

Comment That's pretty neat... (Score 1) 264

... but I'm not sure how it's a "Relativity Shock" as the second links suggests.

Upon thinking about a marble rolling on a rubber sheet I immediately see two big differences between it and a planet moving in space: (i) the marble.. well.. rolls along the sheet, which planets don't do while moving through space; and (ii) the rubber sheet doesn't propagate disturbances at the speed of light (or anywhere close to it).

The State of Ruby VMs — Ruby Renaissance 89

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."
