Interview with Donald Knuth

Andrew Binstock and Donald Knuth converse on the success of open source, the problem with multicore architecture, the disappointing lack of interest in literate programming, the menace of reusable code, and that urban legend about winning a programming contest with a single compilation. Andrew Binstock: You are one of the fathers of the open-source revolution, even if you aren’t widely heralded as such. You previously have stated that you released TeX as open source because of the problem of proprietary implementations at the time, and to invite corrections to the code—both of which are key drivers for open-source projects today.…

Chip offers 5Gbps short-range wireless

A new wireless technology has been developed that should serve as an extremely fast replacement for technologies such as Bluetooth and ultra-wideband (UWB), says Australian research group NICTA. Nicknamed GiFi, the process would use a chip (not pictured) that transmits at an extremely high 60GHz frequency versus the 5GHz used for the fastest forms of Wi-Fi. The sheer density of the signal would allow a chip to send as much as five gigabits per second. While the spectrum would limit the device to the same 33-foot range as Bluetooth or UWB, it could theoretically transfer an HD movie to a…

360° Video

My friend Camilo Telles did his master thesis on this exact subject, he projected this camera entirely in wood and cheap web cameras, he also wrote a software to integrate all the images in one single, it’s not his work, but it’s similar and very interesting.
