10 work skills for the postnormal era – Work Futures

https://workfutures.io/10-work-skills-for-the-postnormal-era-2c07a1009a25 World Economic Forum’s skills list is way out of date. We need new ways to think about — and talk about — this rapidly changing world. Deep generalists can ferret out the connections that build the complexity into complex systems, and grasp their interplay. In postnormal times creativity may paradoxically become normal: an everyone, everyday, everywhere, process.

It takes more than a Circuit Breaker to create a resilient application – RHD Blog

https://developers.redhat.com/blog/2017/05/16/it-takes-more-than-a-circuit-breaker-to-create-a-resilient-application/?sc_cid=7016000000127ECAAY Topics such as application resiliency, self-healing, antifragility are area of interest for many. This article is trying to distinguish, define, and visualize these concepts, and create solutions with these characteristics. So what does a typical resiliency pitch look like: use timeouts, isolate in bulkheads, and of course apply the circuit breaker pattern. I agree with all

Turn Any Surface Into A Touch Screen

http://www.iflscience.com/technology/this-spray-can-turn-any-surface-into-a-touch-screen/ This looks interesting. The technology, called Electrick, was developed by scientists from Carnegie Mellon University in Pennsylvania, with the findings published in an open access paper. The spray consists of an electrically conductive carbon-based material. By applying electrodes to the object, and then measuring the voltage at different points, the position of a person’s finger can

Sinewave DC to AC inverter teardown

I have earlier posted DC to AC inverter teardown that showed wat was inside one cheap “modified sinewave” inverter. Now I do a tear-down to a more expensive “true sineware” inverter PI150S from Velleman. This inverter convers 12V DC to nice sinewave 230V 50Hz AC power  (up to 150W). View to front and back. This unit

Launching Open Hardware Satellites – Hackster’s Blog

https://blog.hackster.io/launching-open-hardware-satellites-93813a1fe842 Created almost twenty years ago the CubeSat standard has lowered the barrier to entry to the point where you can put your own satellite into orbit for not much more than the price of a high end car. The 10 cm × 10 cm × 10 cm cubes have become so common that you can buy
