Please grow your buffers exponentially
Although in some cases x1.5 is considered good practice. YMMV I guess

A cool-looking new debugging tool for C/C++ from Mozilla.
Many, many people have noticed that if we had a way to reliably record program execution and replay it later, with the ability to debug the replay, we could largely tame the nondeterminism problem. This would also allow us to deliberately introduce nondeterminism so tests can explore more of the possible execution space, without impacting debuggability. Many record and replay systems have been built in pursuit of this vision. (I built one myself.) For various reasons these systems have not seen wide adoption. So, a few years ago we at Mozilla started a project to create a new record-and-replay tool that would overcome the obstacles blocking adoption. We call this tool rr.

Low runtime overhead; easy deployability; targeted at 32-bit (?!) Linux; OSS. (via Bryan O'Sullivan)

How to build a Google Chrome extension in 15 minutes
wow. that _is_ easy; wonder if it'd be nearly as easy to write an extension as it is nowadays to write userscripts in Firefox
