Using the LLVM JIT with PostgreSQL can vastly speed up the query execution performance and shows off much potential but it hasn't been mainlined yet.
Dmitry Melnik presented at this month's LLVM Cauldron over speeding up the query execution performance of PostgreSQL by using LLVM. Particularly with complex queries, the CPU becomes the bottleneck for PostgreSQL rather than the disk. LLVM JIT is used for just-in-time compilation of queries.
The inaugural LLVM Cauldron conference happened earlier this month ahead of the GNU Tools Cauldron in Hebden Bridge, UK. All of the slides and videos from this latest LLVM conference are now available.
A quick introduction to Audacity for teachers
School's back in session, and kids love the creative arts. One of my favorite open source creative tools is Audacity, the open source audio recorder and editor. Students love manipulating digital sound with Audacity: making podcasts, learning languages, recording interviews, and recording and mixing music.
I use it to record podcasts for students to provide instructions about classroom procedures and tests. Foreign language students use Audacity to record and play back their lessons. Students can download music and other types of audio tracks for sharing and re-use from Creative Commons and Wikimedia, and dub their own voices onto music tracks, the sounds of birds chirping, whales and dolphins in their natural habitats, and more.

How Red Hat is making money on the public cloud with a hybrid approach
Red Hat hasn't traditionally played much of a part in public clouds, a fact its CEO Jim Whitehurst underscored in Red Hat's recent earnings call. Though the company is now dabbling in a true elastic/consumption-based delivery and pricing model via OpenShift, Red Hat remains a primarily on-premises business that only feints toward a true cloud model in terms of service delivery.
Ironically, the hybrid cloud may be the trend that gets Red Hat fully planted in the public cloud.
