Wesley Aptekar-Cassels published a great list of beliefs about software engineering. The list could be interpreted as wisdom from experience, especially the last point about sleep is more important than choosing a programming language.
A research team at the University of Glasgow have developed a novel way to generate true random numbers. They built an automated robot to manage chemical reactions in crystals which produce inifintely possible physical changes. The robot detects and records the changes in the crystals across multiple variables such as size, location, colour and shape and then converts the images to binary sequences.
Swedish product designers teenage engineering have released a set of 3D printed accessories for the modular IKEA frekvens speaker and light system. They even offer the 3D printer files available for download on their website. This is the best example of a prcatical application for 3D printing that I've seen in while.
Low Tech Magazine descibes the fascinating possibilities of small scale compressed air energy storage (CAES), which are more sustainable than chemical batteries and robust enough to be suited to off-grid living. Parallel use of storage tanks can even allow for variable energy discharge to meet different energy requirements.
The Holistics blog posted about the OLAP cube, the mainstay of enterprise data management for so many years, which is now falling out of favour and being replaced by more efficient parallel processing architecture and column store data warehouses.
Zero Mass Water is a tech company based in Arizona that have developed Hydropanels which use solar power to extract water from captured air vapour. The award winning technology is being rolled out in a consumer product called rexi this summer by the company, at a retail price of $2,500.
