They are also intentionally conflating machine-learning and generative AI slop to confuse and try to make GenAI seem necessary. Google Maps traffic stuff is machine learning, not GenAI, for example. Auto-correct is too. Don't let them make you lose the thread. GenAI slop is slop.
the nyt posts this stuff like avoiding AI for 48 hours is hard and meanwhile i have literally never once intentionally used an AI program for anything ever

There is an example file you can download too; it will even output a Final Cut Pro file with placeholder clips based on the length of dialogue in each scene.

TIL that the solder contacts on different brands of NeoPixel strips have slightly different spacing (but not enough to be a problem with the castellations on this circuit board).
Also, the bonus cat hair comes free with anything from my house! 🤣
