https://opensource.com/article/18/4/introduction-python-bytecode Python source code files; they have names ending in .py. And you may also have seen another type of file, with a name ending in .pyc, and you may have heard that they’re Python “bytecode” files. But beyond “oh, that’s Python bytecode,” do you really know what’s in those files and how Python uses →
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 →
I visited today Product Development Project Gala at Aalto University in Espoo Finland. I tasted pizza made by robots. Ready →
Just received those Potato chips that work like classic TTL logic but up to ~1GHz. Hopefully they will work on my TDR circuit. I should try the chip in this →
Back in the ancient days before sound cards, around 30 years ago, sound cards were rare on PCs. One hack those days was the original Covox Speech Thing, that connected a simple DAC to to PC parallel port. The Covox Speech Thing (also known as Covox plug) was an external audio device attached to the →

https://www.realclearscience.com/lists/biggest_junk_science_2017/2017_worst_junk_science.html In a perfectly logical world, where everyone has adopted science as a way of thinking, lists like this wouldn’t be necessary. Unfortunately, as 2017 demonstrated, we’re nowhere close to that world as junk science is alive and seems to be thriving. →
A solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals. Packaged solid-state relays use power semiconductor devices such as thyristors and transistors. Here are some SSR videos worth to watch: What is a Solid State Relay? https://www.youtube.com/watch?v=wbQiRM9p0j0 Solid State Relay →
http://www.iflscience.com/health-and-medicine/scientists-may-have-found-the-root-cause-of-autism/ Scientists think they’ve found out what could be at the root of autism and, no, it’s not vaccines. According to a new study, it could be caused by having too many brain connections called synapses. “An increased number of synapses creates miscommunication among neurons in the developing brain that correlates with impairments in learning, although we →
