Oracle releases free database

Filed under
Software

Oracle has released its entry-level database, Oracle Database XE, which can be used for development or deployed as a live system at no cost and runs on 32-bit Linux.

Called a "starter" database by Oracle, all applications and data created in XE can be ported to Standard Edition One, Standard Edition, or Enterprise Edition without change.

The license limits the scalability of the database. The database may not exceed 4GB; only a single instance of XE may be run on any one server; it may only use one processor in a server; and it can only use up to 1GB of RAM. The database is also limited to 32-bit operating systems.

If you're happy with those limitations, the database is free to download, develop for and distribute.

Android drone tracks you by computer vision

Kickstarter is showing an $899, Android-based “Mind4″ follow-me drone that tracks you entirely by computer vision, and interprets full-body gestures. Like fellow Kickstarter drone projects AirDog and Hexo+, as well as 3D Robotics’s Iris+, AirMind’s Mind4 quadcopter is designed as a “follow-me” drone for recording videos of a moving target. Unlike these products, however, which don’t run Android or Linux, the Mind4 runs Android on a quad-core, 2GHz ARM processor, giving it the brainpower to run advanced vision recognition algorithms. As a result, Mind4 can track you solely via computer vision via its VAPS (vision augmented piloting system) engine rather than depending on less reliable GPS or tricky manual controls. Read more

ArrayFire Accelerated Compute Library Open-Sourced

The ArrayFire GPU compute library that allows for simplified GPU computing via targeting its own optimized library and API for GPGPU kernel generation than writing your own CUDA/OpenCL kernels, has been open-sourced. ArrayFire is advertised as being faster than other acceleration libraries like Armadillo, Intel Math Kernel Library, etc. ArrayFire supports OpenCL GPUs -- and hardware like the Intel Xeon Phi MIC -- as well as NVIDIA GPUs via CUDA. Last but not least there's also a C programming back-end. Read more

Wormhole in Interstellar Movie Designed with a Linux OS – Gallery

The Interstellar movie has been released not long ago and it was an instant success, despite some of the criticism that has been expressed by a number of physicists. To make thinks even more interesting, at least for Linux users, it looks like the production team used Linux to built the black hole in the movie. Read more
