oh nOOOOOOOOOOOOOO

I think it is sooo frustrating when I show my less techy friends the Hackspace and they are like „Yeah that’s really cool but I could never learn that“ whyyyyyy??? Whyyy do you not think that??? Do you not feel the thirst of knowledge? The desire to create? The freedom of being able to craft something yourself?
Weld shitty, design badly, delete operating systems and break endmills! But just do it!!!
You‘re not dumb if you can’t but when you won’t

I have comitted SR-IOV crimes. A little extension on the pcie_acs_override patchset zen already ships that also bypasses the "External" checks.

This allows me to split the 25GbE Thunderbolt NIC (a ConnectX-4) into 7 VFs (not more, the enclosure doesn't do ARI forwarding, long story, no thunderbolt chipset I have does) in different iommu groups.

And then put one of these VFs into my HAOS VM.

Nice :3

My BlueField-2, finally I managed to get it flashed. Between the rshim driver's console being broken on my CachyOS install, and the card running custom SecureBoot. So many close calls.

But finally, after the last hail mary of trying the default UEFI password and it *worked*. Every password changed, but not the UEFI password, phew.

Meow

I fought very hard for this one log line. But I finally have end-to-end RDMA/SMBDirect between my NixOS NAS and my CachyOS workstation.

On an SR-IOV VIF of the card, without running VMs.

I now have a full archive of all ConnectX firmware. Because I got those cards in all my machines and I am not sure I trust nVidia to keep the download page open forever <.<

As much as I love my cute little Magneto Optical drive, the write speed is...glacial

There. Now I can keep track of how much noise my gear makes in my homelab :3

boys deserve to have an LTO tape library

Resonite Quick Tip, ProtoFlux Overview Mode #resonite

Resonite Quick Tip: ProtoFlux ...

Just dragged out my partner's old X.52 HOTAS because I got an itch to play Project Wingman all off a sudden (yes, its the Jacob Geller video, of course it is).

This is genuinely some of the most just visceral fun I've had playing a game on my own and I'm barely 30 minutes into the tutorial mission.
This is going to get expensive, isn't it?

Project from a couple years ago.

The GameBoy Advance (and SP) can boot via the link cable. This was initially used for multiplayer games to only require 1 cartridge (like Mario Kart: Super Circuit), and then for the GameCube link cable to upload their specific payloads (like in Legend of Zelda: Wind Waker).

To learn the RP2040's PIO, I implemented the controller protocol (joybus) in PIO assembly, at first and then ontop this "remote boot" protocol once I found out they're the same protocol mostly.

Code is: https://github.com/Doridian/Joybus-PIO

Hello I’d like to spend it all please

PSA: Check the thermal paste on your LSI HBAs.

Mine just died so I took the heatsink off and the thermal paste was more a thermal solid.

Repasted the replacements I got immediately and the paste situation was similarily terrifying.
Took a lot of scraping to get it off even.

Anyone know an easy way to get 24V @ 75W out of USB-C with PD? I know even the new 3.1 spec somehow skipped 24V and started with 28V for some reason.
I'd rather not rely on PPS support.

Is the easiest way to just use 20V@4A and use a boost converter? (Or 28V and buck converter)
Or is there something easier already made? I found a couple such devices, but they all have too low current/power limits so far.

And here it is, the dying breath of the card from my system logs if you will.

The [...] section is me cutting out all other registers being just F as well. F indeed.
