This mastodon instance does run on #RISCV processor so it's not necessarily going to be as efficient as a #ARM processor.
Also the measurement is only the local consumption so it doesn't measure how that post impacts on other servers.
Would be interesting to know if anyone else has measured the consumption of a mastodon post.

Morning from my fun new Compiler Explorer mug.
New semester, new version of the xv6 educational OS for RISC-V from MIT! This is accompanied by a new revision 5 of the xv6 book and–for the first time, I think–a Lions' Commentary-style code reader booklet!
A previous version switched to using the stimecmp extension instead of the regular CLINT timer, that was a bit of a surprise. So let's see what the changes in this new version are...

Imagination PowerVR Driver With Linux 6.18 To Support RISC-V - Phoronix
｢ Imagination's open-source PowerVR kernel graphics driver for a while has seen patches extending it to work on RISC-V given that some RISC-V hardware coming to market has featured PowerVR graphics IP. With the upcoming Linux 6.18 kernel that work is landing along with enabling support for the T-HEAD TH1520's GPU ｣
SiFive is super excited about launching its 2nd generation of #riscv vector processor designs today in their "Intelligence" line. www.sifive.com
This is a great series for someone wanting to learn the #RISCV architecture, starting with the registers to assembly, including encoding

Este es un pantallazo del VSCode mientras simulo el código y hago las pruebas. Es bastante cómodo

Para disparar la bola uso el pulsador 0 de la placa simulada. Al hacer click con el ratón comienza la aminación
El simulador es muy básico, pero lo veo muy interesante para enseñar programación del #RISCV

Se utiliza la técnica del subpixel para realizar los cálculos y mapearlos en la pantalla de baja resolucion
Very excited to announce that my talk "Linux on RISC-V: Where we are, where we're going, and how you can jump in" has been accepted for this year's Texas Linux Fest (Oct 3-4) here in Austin TX! I'll also be manning the Austin RISC-V Group booth in the expo area with a bunch of demos. Tickets are still available at https://2025.texaslinuxfest.org/ and I hope you can join me there. #linux #austintx #riscv
Folks, I need your help!
I want to create an Awesome Europe 
list. You all know those Awesome <programming-language> lists, right? Well, this one isn’t about a language, it’s about Europe.
What great IT projects and companies do we have here that can help us Europeans stand on our own feet?
Please share your suggestions so we can make this list truly awesome! PRs are very welcome!
Tiene varios periféricos. Uno es el que ya he mostrado: la pantalla de leds con cuerpo de robot
El simulador permite ejecutar paso a paso los programas directamente desde el VSCODE, sin tener que configurar nada
