https://opensource.com/article/18/7/requests-for-comments-to-knowReading the source is an important part of open source software. But “read the source” doesn’t apply only to code. Understanding the standards the code implements can be just as important. “Requests for Comments” (RFCs) published by the Internet Engineering Task Force (IETF) are important for Internet technologies.This article collected a few RFCs (from thousands →
https://predictabledesigns.com/top-resources-for-hardware-startups-and-makers/ Hardware startups and makers can use all the help they can get. It can be difficult, however, to find resources for developing a physical hardware product (as opposed to software). This article has a list of 30 online resources for those developing new electronic products. This article was originally published on PredictableDesigns.com and there →
https://spectrum.ieee.org/static/chip-hall-of-fame To honor and tell the stories of these renowned blobs of silicon—and their creators and users—IEEE Spectrum has created the Chip Hall of Fame. This is an interesting set of chips to remember. →
https://spectrum.ieee.org/energywise/energy/nuclear/a-double-first-in-china-for-advanced-nuclear-reactors The most advanced commercial reactor designs from Europe and the United States just delivered their first megawatt-hours in China. Both projects were years behind schedule. On Thursday, 29 June, a 1,400-MW EPR designed in France and Germany synced up to the grid at the Taishan nuclear power plant. The next day the U.S.-designed 1,117-MW →
https://www.edn.com/electronics-blogs/eye-on-standards/4460689/The-merger-of-networking–storage–RAM–and-cache Since the dawn of civilization, the computing bottleneck has been the tawdry I/O relationship between disk drives and RAM (random access memory). The emergence of SSDs (solid state drives) loosened but didn’t alter this I/O bottleneck. With fast networks computers can move data onto their disks from remote systems as fast as they can →
https://opensource.com/article/18/7/how-use-dd-linux There’s some truth to that old Unix admin joke: “dd stands for disk destroyer.” If you know what you are using, dd is a simple and powerful image-copying tool that’s been around, well, pretty much forever. There’s all kinds of stuff you can do with dd. In addition to dd this article also introduces →
This is an interesting tutorial series. With it you’ll learn how to design your own custom microcontroller board. This custom 32-bit microcontroller board example is based on an Arm Cortex-M0 STM32 from ST Microelectronics. Tutorial: How to Design Your Own Custom Microcontroller Board — Part 1 https://predictabledesigns.com/tutorial-how-to-design-your-own-custom-microcontroller-board-video-part1/ Tutorial: How to Design Your Own Custom Microcontroller Board — Part 2 →

Biltema sold this ground fault interrupter (RCD / GFCI) device few years ago (does not seem to sell anymore). It is designed to be connected to 230V AC 50 Hz electrical outlet. The information on the back of the device tells that this will trip at 30 mA leakage current. The symbol tells that this →
I got a CEM SMD-100 Smart Electronic Components Tester because it was on sale at very low price. It turned out to be a bad investment. The component tweezers part make very intermittent contact with the meter, so measuring the components was very unreliable. The meter seemed to work OK with the measurement supplied leads →
