BBC: Glow (via) The BBC have released Glow, their jQuery-like JavaScript library developed in house over the past few years. It’s open source under the Apache license.
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.
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.
Stellarium. Really lovely open source planetarium application, for Linux, OS X and Windows.
EveryBlock source code released. EveryBlock’s Knight Foundation grant required them to release the source code after two years, under the GPL. Lots of neat Django / PostgreSQL / GIS tricks to be found within.
Software engineers today are about 200-400% more productive than software engineers were 10 years ago because of open source software, better programming tools, common libraries, easier access to information, better education, and other factors. This means that one engineer today can do what 3-5 people did in 1999!
Let's try to imagine what a Google Silverlight would have been. It would have been a fully open source product from Google, with a very liberal open source license (BSD or Apache). It would have all the technical specifications published openly. They would pledge to have the Silverlight VM interoperate with Javascript and HTML5. And a company like Zoho would have a ton of developers working on Google Silverlight based applications by now - as opposed to having exactly ZERO developers working on Microsoft Silverlight.
PostgreSQL Development Priorities. The top two for 8.4 are “Simple built-in replication” and “Upgrade-in-place”, Josh Berkus is seeking feedback on priorities for future work on 8.5.
djangopeople.net on GitHub. I’ve released the source code for Django People, the geographical community site developed last year by myself and Natalie Downe (it hasn’t otherwise been touched since April last year, so it needs porting to Django 1.1). If you want a new feature on the site, implement it and I’ll see about merging it in.
Reducing XSS by way of Automatic Context-Aware Escaping in Template Systems (via) The Google Online Security Blog reminds us that simply HTML-escaping everything isn’t enough—the type of escaping needed depends on the current markup context, for example variables inside JavaScript blocks should be escaped differently. Google’s open source Ctemplate library uses an HTML parser to keep track of the current context and apply the correct escaping function automatically.
Ext Core 3.0 Beta Released. The Ext JavaScript team have just released the core library (similar to jQuery or Prototype) under an MIT license. The rich GUI elements that go on top are still under the GPL.
DB2 support for Django is coming. From IBM, under the Apache 2.0 License. I’m not sure if this makes it hard to bundle it with the rest of Django, which uses the BSD license.
Whoosh. A brand new, pure-python full text indexing engine (think Lucene). Claims to offer performance in the same league as wrappers to C or Java libraries. If this works as well as it claims it will be an excellent tool for adding search to projects that wish to avoid a dependency on an external engine.
Apache Qpid. A new open source AMQP message queue with implementations in C++ and Java, developed by engineers from Red Hat, IONA and JP Morgan Chase. Anyone tried this yet? Looks pretty good on paper.
google-mobwrite. Neil Fraser’s terrifyingly clever differential synchronization algorithm (for SubEthaEdit-style collaboration over the web) is now available as an open source Python and JavaScript library.
Project Voldemort. Yet Another “big, distributed, persistent, fault-tolerant hash table”—this time from LinkedIn, released under the Apache 2.0 license. The approach to consistency is interesting—instead of using distributed transactions, they use versioning and “resolve inconsistencies at read time”. It also uses consistent hashing (as seen in libketama) to select servers. The design document has lots more information.
The simple truth is that in the age of Web 2.0/3.0, in the era of cloud and utility computing, the application server is a commodity. A commercial, proprietary app server simply cannot survive in this environment anywhere outside the lethargic, soft-padded walls of the enterprise.

[In Mali...] The outcome of this rampant illegal software copying is that Windows is seen as "the first world standard" and any attempt to push a cheaper alternative is strongly resisted. They consider it trying to cheat local people out of getting the same quality of software that is used in the developed world, even though it's a legal way of getting quality software for free.
OurDelta Builds for MySQL (via) A community supported “alternative distro” of MySQL, incorporating new features from Google and other sources by maintaining a clean set of patches against the MySQL source tree (which I guess is why it’s not considered a fork). I recognise some of the patches from the excellent “High Performance MySQL, 2nd Edition”.
License Hacking. Wikipedia is making the switch to a CC license, by asking the Free Software Foundation to include that as an option in the latest version of the Free Documentation License which Wikipedia currently uses and which includes an auto-upgrade clause. Devious.
Windows Server and SQL Server on EC2 (via) Launched today, the pricing includes rental of the Windows license. Regular Windows is 25% to 50% more expensive than Linux, but SQL Server comes in at a hefty $1.10 per hour, which is $9636 per year (nearly three times as much as a Linux server running an open source database).
The only down side is everyone I’ve talked to at Freebase seems pretty solid on this being their proprietary secret sauce, because a good, fast scalable open source tuple store might actually jump start a real semantic (small-S) web after all these years.
Cappuccino Web Framework. Now open source (LGPL)—the Objective-C-in-JavaScript web application toolkit from 280 North, who are speaking at this year’s FOWA in October. Beautiful logo.
Announcing dmigrations
The team at Global Radio (formerly GCap Media) is the largest group of Django developers I’ve personally worked with, consisting of 14 developers split into two scrum teams, all contributing to the same overall codebase.
[... 625 words]Chromium. Google Chrome is out! Here’s the open source project, including the code for the new V8 JavaScript virtual machine.
Free licenses upheld by US “IP” court. Free software and CC licenses which dictate conditions that, when violated, turn you in to a copyright infringer now have precedence in US law.
The Price of Anonymity: Our Principles? Alex Russell calls for a constructive step towards better gender balance in open source: make it clear that misogynistic, offensive and lewd behaviour will not be tolerated by open source communities and bake that policy in to community codes of conduct.
FLOSS Weekly 34: Django. Randal Schwartz interviewed Jacob Kaplan-Moss at OSCON for the consistently excellent FLOSS Weekly podcast.
What the Heck is the Open Web? Brad Neuberg is seeking a two sentence definition. Bonus points for answering the following: “If Adobe were to open source Flex/Flash, or Microsoft Silverlight, would that be the Open Web? If so, why? If not, why not?”
Protocol Buffers: Google’s Data Interchange Format. Open sourced today. Highly efficient binary protocol for storing and transmitting structured data between C++, Java and Python. Uses a .proto file describing the data structure which is compiled to classes in those languages for serializing and deserializing. 3-10 times smaller and 20-100 times faster than XML.
