thanks, Wikipedia, I'm always getting undead wizards confused with algae.

amazed at the number of people asking "but why am I paying more than the price of the item in import fees if the tariff is 145%?"

I didn't realise that mathematical and financial literacy was quite this poor.

(yes, the tariffs themselves are ludicrous, but that's not my point here)

@azonenberg ah ok. I just got a cheap compressor with my airbrush kit and I've ended up using it to dry stuff off and to blow out dust and crud far more than I have actual painting

used my air compressor to blast out a bunch of crud from my keyboard, took a while, and I started smelling something weird.

turns out it's not all too happy about being run at high duty cycles from max flow rate, and the whole pump assembly was so hot I couldn't touch it for more than a fraction of a second. real toasty.

got a fan on it, gonna let it cool off.

@azonenberg surprised that the cans have fewer contaminants than compressed air - is it because the propellant tends to boil off?

y'know when you want to implement switch debouncing, and every single time you realise you haven't got a clue what the bouncing actually looks like and end up just fudging the numbers until stuff seems to mostly work as intended?

well here's some actual data! I took a bunch of different switches I had laying around and measured their bouncing behaviour, during both close and open.

graphs in the repo, CSV data available in releases.

@whitequark I've scaled down on that front since signal got a fair bit better for small group chats, but yeah, telegram is at least stable and actually delivers messages reliably and hasn't really required any thought from me aside from dealing with a few spam incidents.

@whitequark amazingly people still routinely get pissy with me when I refuse to use the damn thing.

someone asked for pictures of the insides of one of my Cosel 5V 200A power supplies.

pretty hard to get good photos because it's so densely packed. it's an older design so no fancy GaN HEMT stuff, but still some excellent power electronics porn.

they feature something I've never seen before: capacitors covered by these plastic domes. at first I thought they were current sensing transformers, but nope, they're definitely capacitors - the silkscreen markings have C-prefixed refdes and they have polarity markings.

I'm fairly sure this is for thermal isolation, since they're right up against two heatsinks that'll be getting mighty toasty.

paywalled standards need to fuck off straight into the sea. truly one of the worst types of rent-seeking.

@ryanc I'd buy the gold plated one and then remove the plating with sandpaper as a matter of principle

@GossiTheDog aw it's a shame talos put this out, I used to know a lot of great folks over there

cursed thought: you could do ICSP programming with a SATA cable, and it would be a convenient format given that they're cheap and have a retention clip.

@GossiTheDog I suspect part of that is that most of us are sick to death of it

man drewski's arma videos have been fun recently. makes me want to play again, but I know I'd run up a hill for 20 minutes and then get shot from out of nowhere and repeat for an hour before ragequitting. I am, uh, not very good at games.

@q3k tens of megabytes of code is legitimately frightening. I think we tend to forget just how ludicrous that is in terms of the instruction count now that so many things come with an entire browser engine or pile of UI assets bundled.

@leftpaddotpy my personal view on software licensing is that licenses have no benefit at all for individual developers and users, because all enforcement is fundamentally tied to capital and legal frameworks that are designed to protect the rich from the poor. the sensible response is the anarchist one: ignore licenses entirely and do what you want.

literally the only reason I MIT license my code instead of no license at all is that it makes tedious reply guys leave me alone.
