http://www.epanorama.net/newepa/2015/01/14/garrettcom-converter-teardown/ I did more than two years ago tear-down of this 100 Mbit/s copper to fiber Ethernet media converter (link above). Now I decided to try to fix it. It turned out that originan PSU did not put out right 3.3V voltage, but considetably less. The digital electronics worked out nicely when fed with 3.3V →

Or is it? HoloKitis an extremely clever DIY solution for a quick and dirty augmented reality experience with →
https://opensource.com/article/17/5/secure-open-source-devops?sc_cid=7016000000127ECAAY The key to secure app development is to “shift left”—move security testing away from late-stage production and back towards design and development. →
https://hbr.org/2017/06/11-things-the-health-care-sector-must-do-to-improve-cybersecurity No industry or sector is immune to hacking. That reality was made painfully clear in mid-May, when a cyberattacker using WannaCry ransomware crippled health care institutions and many other kinds of organizations around the world. In 2015 over 113 million Americans health records were exposed, and in 2016 the number was over 16 million. Experian predicted that the →

https://blog.hackster.io/death-of-moores-law-makes-open-hardware-possible-7aaad86e47bf Bunnie argued that while Moore’s Law held if you started developing a project at the point when a vendor released their silicon it would be obsolescent even before you managed to ship it. We may well have reached the point where our computing is “good enough.” That, at least as far as computing is concerned, we’re →
https://blog.hackster.io/the-choitek-megamark-robot-does-it-all-33b3a8bb6cfe Many robots are tasked to do one, or several related operations, and do them well. The Choitex Megamark, however, from Carnegie Mellon computer science student John Choi, can perform a variety of actions, though currently it doesn’t appear to do them very well at all. →
