Stellarium. Really lovely open source planetarium application, for Linux, OS X and Windows.
From Microsoft: C# and CLI under the Community Promise. Microsoft’s assurance that it won’t “assert its Necessary Claims” against alternative (including open source) implementations of the ECMA C# and CLR specifications. The promise doesn’t cover implementations of .NET, WinForms etc- so the Mono team have announced they will be splitting their project in to two packages—a safe, ECMA based package and a package containing everything else.
Up and running with Cassandra. Twitter are beginning to use Cassandra, the open source branch of Facebook’s BigTable-like non-relational database. Evan Weaver explains how to get started with it, but warns that it’s not yet a good idea to trust data to it without having a full backup in an unrelated storage engine.
Yahoo! proposal to open source “Traffic Server” via the ASF. Traffic Server is a “fast, scalable and extensible HTTP/1.1 compliant caching proxy server” (presumably equivalent to things like Squid and Varnish) originally acquired from Inktomi and developed internally at Yahoo! for the past three years, which has been benchmarked handling 35,000 req/s on a single box. No source code yet but it looks like the release will arrive pretty soon.
In defense of web developers. Zeldman: “The social benefit of rethinking markup sealed the deal. XHTML’s introduction in 2000, and its emphasis on rules of construction, gave web standards evangelists like me a platform on which to hook a program of semantic markup replacing the bloated and unsustainable tag soup of the day.”
Solved: where the civil servant really wrote that message to Hazel Blears. There’s an interesting usability / understanding-of-technology story here.
