Linux ovunque! Cresce il mercato dei server casalinghi e #steam su Linux raggiunge un nuovo record di utenti.
C’è infatti una verità assoluta ed oggettiva a proposito di Linux: magari non sarà il sistema operativo più usato dagli utenti casalinghi, ma è certamente quello alla base dell’intero cloud. Almeno secondo quel che diceva Fortune nel 2024, il quale attribuiva a Linux una quota del 63.1% di base di installato. -

@shadowfals I agree. I like this formulation.

So much for #StatesRights
#Trump signs #ExecutiveOrder to neuter #State #AI laws, a win for #tech companies & #billionaires that have #lobbied against #regulation of the #technology.
The order would create one federal regulatory framework for #ArtificialIntelligence, Trump told reporters.

@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.
