Nous voilà sur le fédiverse !
Tubercule est un collectif de hackeuses et hackeurs de la région de Rennes qui se veut inclusif et accessible.
Notre but est de créer une communauté d'entraide numérique afin de reprendre en main nos moyens de production et nos vies numériques en développant des savoirs, outils et méthodes accessibles aux collectifs.
N'hésitez pas à nous suivre et consulter nos projets sur https://tubercule.fr

Bienvenus, il y a toujours besoin de gens qui hackent ce que ce soit (je viens de lire votre FAQ à ce sujet) 😁

Btw, just found the v2 release announcement of @fedify and that is a prime example on how, on the grassroots environment end of the spectrum we can maneuvre into better territory.
Kudos to the #fedify developers. Handing people tools they need to focus on solutions, and build without getting thrown into deep on-the-wire impl detail reeds to worry about.
That is the positive side of the equation. There's not only a big uptick in interest for the #SocialAPI i.e. #ActivityPub client-to-server, which offers new opportunity to correct course. But also are there more #FOSS projects focused on robust tool and library support for the 'Solution developer' stakeholder.
In the revamp of the delightful commons initiative, made possible with support of @nlnet I emphasized all these projects, while I de-emphasized the apps that are already doing good for themself, but contribute to further divergence from open standards.

Inside a Compact Intel 3000 W Water-Cooled Power Supply
Recently [ElecrArc240] got his paws on an Intel-branded 3 kW power supply that apparently had been designed as a reference PSU for servers. At 3 kW in such a compact package air cooling would be rather challenging, so it has a big water block sandwiched between the two beefy PCBs. In the full teardown and analysis video of the PSU we can see the many design decisions made to optimize efficiency and minimize losses to hit its 80 Plus Platinum rating.
For the power input you’d obviously need to provide it with 240 VAC at sufficient amps, which get converted into 12 VDC at a maximum of 250 A. This also highlights why 48 VDC is becoming more common in server applications, as the same amount of power would take only 62.5 A at that higher voltage.
The reverse-engineered schematic shows it using an interleaved totem-pole PFC design with 600 V-rated TI LMG3422 600V GaN FETs in the power stages. After the PFC section we find a phase-shifted full bridge rectifier with OnSemi’s SiC UF3C065030K4S Power N-Channel JFETs.
There were a few oddities in the design, such as the Kelvin source of the SiC JFET being tied into the source, which renders that feature useless. Sadly the performance of the PSU was not characterized before it was torn apart which might have provided some clues here.
