  • Dimmers will typically use a triac which cuts up the sinusoidal waveform. It doesnt actually lower the amplitude per se, but it limits the fraction of the time the waveform is on. Kinda like this. This means that a lot of the time the led isnt gettingas much or any power. The average power will be lower, and if the LED driving circuitry isnt designed to compensate for this, the LED will flicker.

    Clarification on triacs: they get turned on a certain fraction of the way into the cycle. Triacs will stay on until the voltage across them is 0. Conveniently the zero-crossing of the AC wave (when the wall voltage crosses zero to start foing negative or from negative to positive) does just that.



  • Linux wont take off until the friction for new users is low enough that the layman can resolve issues without resorting to techniques outside of their understanding and patience. Even as someone who uses linux, there are a ton of things that should have a GUI / just be a context menu entry. If you can get the same amount of work done with a button click rather than typing out a complicated command line string, you might as well use the GUI, right click menu, etc. and make it easier for the typical person. People these days can barely use tablets, and those already dumb things down to icons you tap. Unfortunately, making it accessible to the lowest common denominator is what makes things popular a major factor in making things popular


  • Also if you want a domain but dont care about the actual address, a .xyz domain composed entirely of numbers with less than 10 digits is $1-2 + same as renewal fee per year. $1.22 for me on porkbun

    Just be sure to redact the whois information bc you will get a call from scammers trying to get you to register your domain on some “internet map” for a small fee acting as if its some step in your setup process you havent done yet
