I write posts and try to do them daily or at least weekly. Check out my site (tristanxr.com) for my latest posts. I often write about topics like ARM, RISC-V, NixOS, and things I am interested in or involved in.

Is debugging through OpenOCD really that slow when going through JTAG?

Hardware is all fun and games until you run into timing issues, non-deterministic behavior, and over complicated designs to work around stupid bugs.

@grhmc @jamonholmgren Sometimes its like watching paint dry

@jamonholmgren Ci runs mostly during the day

Tech companies pay a lot of money for CI servers and then have a bunch of super powerful Mac hardware sitting idle for 16 hours a night. Hm.

@ElectronNest はい、でもそのコンピュたは素敵。

故障した時面倒臭い。

@JoeSpeeds Do it, an Arm based workstation that looks like this would be awesome.

@RossComputerGuy we can rebuild him, we have the technology

Imagine a 256 core, 4TB RAM, 2PB storage, 128GB of VRAM workstation looking like this.

@snwy_me That would be minimum

@RossComputerGuy only 256 core?

@domenkozar @bereknyei That definitely sounds interesting.

American friends, we're going to organize a Nix sprint in Mexico over the summer. Rent a villa near a surf beach, do a bunch of brainstorming, hacking and enjoying tacos. Who's in?

I sat on the couch to wait for my lunch to cook. Now I have a cat napping on my leg.

Yep, and that system will be solid. The only issue I've had is a lack of enough memory. Really wish Apple would allow for memory upgrades. I don't feel like spending $2k for a new machine just for more RAM. You should install COSMIC, it plays very nicely with the GPU on Apple Silicon and the out of the box experience is perfect.

Wow. Install experience of #asahi was seamless. 10 hour battery life ? 600 M2 laptop from Craigslist. I'm sold. How can I contribute. #Nix is on Fedora officially too.

@kmcnam1 When I had a laptop with an NVIDIA GPU, sure. But I've been on Apple Silicon and 10 minute is a lot.

@carlrichell That's great, I really hope it works out. Open source definitely needs to live on.

@RossComputerGuy We hope to make sensible, strong arguments for excluding open source which then becomes a standard for other states. It's going to be difficult.

Went to the capitol today to meet Sen Ball, Rep Paschal, Rep Ricks, and three additional Denver constituents with concerns about SB26-051's effect on open source software, privacy, and security. It was an hour and a half meeting that could have gone longer if it weren't for the building being shut down. Our concerns were heard and shared. The next step is exchanging and discussing specific language changes to the bill including an exemption for open source software.

@FRIERENcontents It's great

Frieren with short hair

@grhmc If it makes you feel better, it could be "(1.0).into()"

this should be illegal:

@taxspendlib Nix fixes this

pip is the worst package manager ever

It'd be really cool if @system76 managed to use some of the work @oxidecomputer has been doing in the HW space for custom linux machines at some point in the future

CVE-2026-3731 is now fixed in Determinate Secure Packages, both standard and FIPS variants.
