i've been doing some computational number theory with python (read, gmpy2 and kim walisch's primesieve), but i've only really found fast semiprime testing code in PARI that needs to be compiled with gcc

is windows 11 WSL generally good enough to compile arbitrary c code with gcc for projects these days?

Also, weirdly, using aluminum foil is only colloquially suggested for removing rust from chrome and not bare ferrous metal, but this reaction would suggest it would work just as well in that case.

I'm not sure how to identify the type of chrome plating used on the tool I'm restoring, so it could be a reaction with that. But I am fairly confident the rust is coming from pitting in the plating exposing the iron in the tool beneath it

It does seem like the reaction creates ONLY a black powder afterward, with none of the red/orange rust anywhere to be seen. So unless there is a reaction between the rust and air/moisture as a result of the abrasion, it would seem like this reaction is occurring. If I'm understanding correctly, it's exothermic and the heat from the abrasion friction could get the reaction started, and I really don't have any other explanation for why the byproducts of this product are black and not orange.

Consensus from a google search is that it's mostly abrasion, not dissimilar to using steel wool, but someone did suggest that the...

Consensus from a google search is that it's mostly abrasion, not dissimilar to using steel wool, but someone did suggest that the reaction: 3 FeO + 2 Al ⟶ 3 Fe + Al_2O_3 might also be happening.

I have been trying to find cheap, nonhazardous ways to remove rust/corrosion from ferrous metal/chromed ferrous metal. and I happened upon a technique for removing rust from a chromed surface with just aluminum foil. (and a bit of soapy water, I assume to break surface tension and lift away freed rust/byproducts). It seems to work well enough, but I want to understand the phenomena more.

I love hand tools, they're like a testament to the fact that given enough time, dedication, and care you can always achieve your goals, no matter what advantages others have. sure you won't be as fast as someone who has expensive brand new power equipment, but pouring effort into a goal can always get you there, and is usually more fulfilling than buying your way through every problem.

I realize I'm preaching to the choir here, but facebook marketplace's algorithmic feed is SO infuriating. It has filters and categories that allow me to restrict a search to what I actually want, but then it just.... doesn't.... 3/4 of the "feed" is always ads/dropshippers, and then the rest is just not in the location range that you set.

But unfortunately I want to buy used goods more than I want to not use shitty software.

update: I have successfully housed the entire setup in an antique buffet, which had two lateral cabinets that were sized exactly perfectly hold the ugly bose speakers. only thing now is to fix the electrical (ground loop?) hum. I wonder if speaker cable being too long can cause inductive electrical humming

wondering about the most eco friendly way to dispose of very very old bituminous coal in my house (old coal bins in the basement).

i'd prefer to reclaim the space and remove carcinogens from the premise, so leaving it in place is not optimal

seems like wetting it and putting it in a thick garbage bag, then sending it to the landfill, would be the closest thing to carbon sequestration i can realistically achieve.

I wish every item I needed to purchase had an itemized breakdown of the costs. e.g.
materials $10
labor $2
shipping $6
profit $20

it's weird that last leg shipping is usually broken out but not the rest, although I imagine if this was true I would buy even more things second hand
