Switching diodes and rectifying diodes

I had an envelope full of SMD diodes arrive today. Three different types in three different sizes, so nine bundles. Unlabeled!

I’m not sure what they were thinking at the shop. I got them from here.

I managed to figure out that the ones marked ‘S4’ were the Schottky diodes (1N5819WS). I think the ones labeled ‘T4’ are the switching diodes (1N4148WS) and the ones labeled ‘T7’ and ‘A7’ are the rectifying diodes (1N4007), but I’m not sure of that yet.

I asked ChatGPT for help and it explained how I can devise a test circuit, so that’s on my TODO list for tomorrow.

Who is the girl in Massive Attack?

I asked ChatGPT who is the girl in Massive Attack? It told me:

I think that’s a pretty good answer. The girl I was thinking of was Elizabeth Fraser who sings Teardrop. Horace Andy is a man, not a woman, but ChatGPT just listed him as an aside, it didn’t claim he was a woman.

I checked Massive Attack band members and there were a few other female collaborators which ChatGPT didn’t list, but it didn’t hallucinate anything or tell me any lies. I’m not sure if I should give ChatGPT a B grade for missing a few female collaborators, or an A for giving me a simpler answer which contained the fact I actually wanted to know, viz who is the girl who sings Teardrop?

Mo says there are some things we shouldn’t waste time talking about because they are going to happen, inevitably. These are:

  1. There is no shutting down or reversing AI, we can’t stop it
  2. AI will be significantly smarter than humans
  3. Bad things will happen in the process of developing AI (the specifics to be determined)

…and the fourth inevitability? Utopia..?
