A modem designed specifically for Africa has been announced at the TEDGlobal conference in Edinburgh. The device combines rugged design with a range of connectivity options, switching between wi-fi, 3G and fixed broadband. Ushahidi, the Kenyan tech firm behind BRCK, believe Africa-specific hardware is long overdue.

Late last year, I wrote about the EFF’s project to leverage the Patent Office’s new Preissuance Submissions procedure to promote open 3D printing technology. Here we are, several months later, and the fight for open 3D printing continues. Now, the EFF has partnered with Ask Patents to facilitate crowdsourcing of prior art searches for various 3D printing-related patent applications.
While still a ways from being comparable to the proprietary graphics drivers in terms of features and OpenGL performance, the open-source GPU drivers found by default in the forthcoming Ubuntu 13.04 release are a big improvement over the out-of-the-box graphics drivers found in earlier Ubuntu Linux releases. The Ubuntu desktop is also faster thanks to improvements to its Unity desktop environment and Compiz compositing window manager. In this article are Linux gaming benchmarks looking at the performance of Fedora 17, Fedora 18, Ubuntu 12.10, and a preliminary Ubuntu 13.04 development snapshot. In this first article, the OpenGL performance of Intel and Radeon graphics are being benchmarked.

Here's a cool little crowd-sourced project from the National Severe Storms Laboratory and the University of Oklahoma. (Boomer Sooner!) The "Precipitation Near the Ground" project (aka W-PING) uses reports from civilians (that's you and me) to match against what radar sees. And as noted in the app description, radar doesn't see too well near the ground at long distances, and those snazzy automated sensors that can tell the difference between snow and rain and some dude spitting in the gutter are found only at airports.
That's where you and I come in. If it starts raining or snowing or whatever it does wherever you are (here in Florida it's either "build an ark" or "welcome to Hell"), fire up the app, let it detect where you are, then choose the closest description to what it is you're seeing, particularly with cold-weather storms.
Think of it as a cool way to give a little back to science, when science has given so much to you.
