Made something of an expensive mistake last night dropping a big pot on the induction hob. The cost of repair is about the same as a new unit so I’ve ordered one on AO with measurements from the old and new data sheets and I just hope that it can be swapped like-for-like by the AO installer without involving a kitchen fitter.

@alxd you're missing the other half of human knowledge, project gutenberg (also available as a kiwix dump), but it adds another 90GB or so.
currently my “sum of human knowledge” disk is at around half a TB, of which 395G are kiwix dumps (the rests are mostly distros and a few odd small things), and it's a bit more than would easily fit on a pendant, but the pendant look would be really cool!

@Soft_machine @bbacc secondo me visto l'approccio il posto migliore dove stare sono le mura (certo, per stare sulle mura il biglietto non serve, ma...)
i tendoni hanno come scopo di venderti fumetti e giochi (ok, volendo essere generosi in qualche caso “di farti conoscere fumetti e giochi”) e gadget (questi senza opzioni generose)
le mura sono più una festa di carnevale, però nerd
(anche le strade in generale, ma le mura soprattutto)

per la serie muffa consiglia cose:
Hal & Harper, serie tv appena uscita.
arrivato al terzo episodio e mi sta piacendo molto. speriamo non sminchino tutto alla fine. ma con sto cast sono fiducioso.
quale cast? Mark Ruffalo, Lili Reinhart e Cooper Raiff. adoro tutti e tre un casino.

@thatgiga @bbacc Io ricordo quello che mi faceva mia nonna quando stavo male. Non so che quantitativo usasse, so solo che ci metteva il burro e tanto parmigiano, per farmi riprendere. Adesso mi mancano entrambi: il riso burro e parmigiano e mia nonna 😭

@francescotoniolo Ma dai! Sai che l'ho intervistata non troppo tempo fa per parlare del suo Non è una storia di zombie?

I stopped in one of my favorite spots to see if there were any mushrooms. I moved around a few leaves. I swear there wasn't even any burdock nearby. I tried to take them off. First photo by me. Second photo by my husband, by necessity.

Thermite Pottery Fires Itself
Finely powdered aluminium can make almost anything more pyrotechnically interesting, from fireworks to machine shop cleanups – even ceramics, as [Degree of Freedom] discovered. He was experimenting with mixing aluminium powder with various other substances to see whether they could make a thermite-like combination, and found that he could shape a paste of aluminium powder and clay into a form, dry it, and ignite it. After burning, it left behind a hard ceramic material.
[Degree of Freedom] was naturally interested in the possibilities of self-firing clay, so he ran a series of experiments to optimize the composition, and found that a mixture of three parts of aluminium to five parts clay by volume worked best. However, he noticed that bubbles of hydrogen were forming under the surface of the clay, which could cause cracks during the firing. The aluminium was reacting with water to form the bubbles, somewhat like a unwanted form of aerated concrete, and for some reason the kaolinite in clay seemed to accelerate the reaction. Trying to passivate the aluminium by heating it in air or water didn’t prevent the reaction, but [Degree of Freedom] did find that clay extracted from the dirt in his back yard didn’t accelerate it as kaolinite did, and the mixture could dry out without forming bubbles.
This mixture wasn’t totally reliable, so to make it a bit more consistent [Degree of Freedom] added some iron oxide to accelerate the burn through an actual thermite reaction – some mixtures burned hot enough to start to melt the clay. After many tests, he found that sixteen parts clay, seven parts aluminium, and five parts iron oxide gave the best results. He fired two cups made of the mixture, a thin rod, and a cube, with mixed results. The clay expanded a bit during firing, which sometimes produced a rough finish, cracking, and fragility, but in some cases it was surprisingly strong.
The actual chemistry at work in the clay-aluminium mixtures is a bit obscure, but not all thermite reactions need to involve iron oxide, so there might have been some thermite component even in the earlier mixtures. If you need heat rather than ceramic, we’ve also seen a moldable thermite paste extruded from a 3D printer.
