Quite by chance, I stumbled across the good old #zines (still existing/coming back?). I remember them from the 1980s/90s. Are zines really a thing again?
Can you tell me more about them? Is it a new cultural phenomenon, why do you like or make them? I'm super curious and fascinated!
Here some history: https://en.wikipedia.org/wiki/Zine

@francina1909 ma la domanda corretta è?
Perché ci facciamo mille menate quando la nostra esistenza è una briciola nell'universo ?
Fra 10-20-30 anni non ci saremo più, fra 100 non saremo nemmeno ricordati, quindi godiamo del ora e adesso, siamo troppo piccoli per avere un impatto, pure minimo, su qualsiasi cosa. Tutto quello che ci fa stare bene è buono, quello che ci sta fare male è male, a prescindere.
Il resto serve solo ad ingrassare le tasche dei psicoanalisti...

Sud-est asiatico: scontri al confine thailandia-cambogia. cosa sta succedendo? il punto con la giornalista junko terao
@anarchia
Proseguono gli scontri lungo il conteso confine tra Thailandia e Cambogia in quello che è un conflitto che da decenni si trascina su una frontiera mai completamente delimitata. A luglio un’altra

Designing a Simpler Cycloidal Drive
Cycloidal drives have an entrancing motion, as well as a few other advantages – high torque and efficiency, low backlash, and compactness among them. However, much as [Sergei Mishin] likes them, it can be difficult to 3D-print high-torque drives, and it’s sometimes inconvenient to have the input and output shafts in-line. When, therefore, he came across a video of an industrial three-ring reducing drive, which works on a similar principle, he naturally designed his own 3D-printable drive.
The main issue with 3D-printing a normal cycloidal drive is with the eccentrically-mounted cycloidal plate, since the pins which run through its holes need bearings to keep them from quickly wearing out the plastic plate at high torque. This puts some unfortunate constraints on the size of the drive. A three-ring drive also uses an eccentric drive shaft to cause cycloidal plates to oscillate around a set of pins, but the input and output shafts are offset so that the plates encompass both the pins and the eccentric driveshaft. This simplifies construction significantly, and also makes it possible to add more than one input or output shaft.
As the name indicates, these drives use three plates 120 degrees out of phase with each other; [Sergei] tried a design with only two plates 180 degrees out of phase, but since there was a point at which the plates could rotate just as easily in either direction, it jammed easily. Unlike standard cycloidal gears, these plates use epicycloidal rather than hypocycloidal profiles, since they move around the outside of the pins. [Sergei] helpfully wrote a Python script that can generate profiles, animate them, and export to DXF. The final performance of these drives will depend on their design parameters and printing material, but [Sergei] tested a 20:1 drive and reached a respectable 9.8 Newton-meters before it started skipping.
Even without this design’s advantages, it’s still possible to 3D-print a cycloidal drive, its cousin the harmonic drive, or even more exotic drive configurations.

@mathewi@journa.host I'd say less that the social web is dying, it's quite alive and well on the Fediverse.
I'd argue that the social web as it currently stands is being abandoned by the very companies that made it.

@VE2UWY @AaronDavid was it ever "open-sourced"?

@filippodb @lalchimistadigitale @spettacoli beh già nel 1985 non è che fosse così al top. È una produzione italiana al risparmio e non sono neppure così sicuro che abbia mai visto la pelle di un tamburo. Ma il groove, anche se sintetico, funziona e il ritmo vagamente in controtempo potrebbe addirittura ricordare (bestemmio) Blue Monday dei New Order

@fucinafibonacci @lalchimistadigitale @spettacoli quindi il buon sandy lo piazzava ano a caso con batteria o pianola a tracolla a seconda del progetti tanto era tutto in playback anche questo credo...
Però invecchiato malissimo il video.
