> It's fine to rewrite copyright in a way that explicitly allows things like Copilot, as long as FOSS gets to copy bits of proprietary code, too. This is exactly what I was thinkin…

The position of the FSF is severely misrepresented by the title. Open the full article, you'll see that all FSF says is GitHub Copilot is proprietary software and SaaS, and all for…

Note: The author is not entirely serious. It's part of a series called Mystifications: A short series of semi-satirical pop science articles, called "Here's why we don't understand…

> This is a new idea, and has barely been tried. What do you think? As the author later pointed out: it's not a new idea, FreeBSD has been doing it for decades. Nevertheless, I agr…

Usually it's inductor coils and transformers, occasionally it's ceramic capacitors (all grades other than NP0 are microphonic, SMD or not), both problems are common in switched-mod…

I remember seeing an interesting Audio Engineering Society's presentation (2005) [0] on a similar problem in balanced audio interfaces. Interestingly, an old-school audio transform…

The experienced and mysterious audio engineer "NwAvGuy" [0] praised the virtue of using two gain stages and moving the volume control away from the first input to reduce Johnson no…

Fun fact: for the most demanding RF applications, namely, radio astronomy, the front-end low-noise amplifiers are indeed cooled to cryogenic temperature by liquid nitrogen. Here's …

I always want to make a nice-looking infograph for Wikipedia on the TV color bars, with colors, labels, and explanations of the staircase waveforms, black level, color burst, etc (…

I bet many people will say that today's circuit boards are so cheap and making one at home is just too troublesome - and these days you can't make a good digital system on a two-la…
