Gracana··on Chestnut – eGPU dock with open-source firmware
I'm surprised that it's pretty much the same as the adapters you can get on aliexpress. Not even a case to protect it from feet in the passenger footwell. Especially compared to the windshield-mount unit, which looks like a very slick product. I suppose they can always improve it if there is interest in this first version.
Gracana··on Why does Opus 5 feel worse to work with?
That’s a good one. And yes, of course I mean its history of usage in computing, not in general.
Gracana··on Why does Opus 5 feel worse to work with?
I wondered how far back the usage of that term went. I was familiar with it in patch, so I did a little digging and found it in the v1.3 (1985!) source by Larry Wall: https://groups.google.com/g/mod.sources/c/xSQM63e39YY
Gracana··on The Water Footprint of AI
What influence do you have over these companies where your trust or distrust matters?

[edit] This is an awfully pessimistic take. Even if these companies will largely do whatever they like, some of us can at least make choices to use alternatives. That is probably what you were getting at.

Gracana··on CP/M-386 – CP/M for 386 protected mode, derived from CP/M‑68K
It also has an “ed” that will make you miss UNIX’s “ed”. I’ve used it to write programs and it is not fun!
Gracana··on ReFrame – The EPaper Camera
If the printer doesn't extrude sufficient volume for the speed it's moving at, the layer lines become thin and leave gaps. It's more apparent in this picture: https://qidi3d.com/cdn/shop/articles/under-extrusion.jpg
Gracana··on Now is the time to give LLMs access to the ACM digital library
> From January 1, 2026, all ACM publications will be published Open Access (OA), free to read, share, and reuse in the ACM Digital Library.
Gracana··on When can a power company take your land for data center infrastructure?
I was looking at buying a house with big transmission lines crossing over the property. It was a misty not-quite-raining day when I went to look at it, and you could hear the lines crackling and humming the whole time you were outside. I figured I’d have to give up ham radio if I moved there, ha.

Gracana··on GLM-5.2 – How to Run Locally
You don't have to have a server, workstation motherboards support lots of memory channels.

I was lucky to buy a lot of RAM before prices skyrocketed. I knew I wanted to play with this stuff, so I spent what felt like a lot of money at the time to buy 8x96GB DDR5-6400 RDIMMs. Now the same RAM costs at least 6x more.

Gracana··on Akse3D – open-source 3D modelling anyone can master
I think that's a lot better. "Please explain your wrongness" really had me scratching my head. Hopefully they can make improvements to the 3D architecture or find someone who can help.
Gracana··on DeepSeek Introduces Vision
You're right, it's just additional text that allows it to do thinking / reasoning-like behavior. The big proprietary models hide the real output from the user and instead provide a friendly abridged version, but that's just to protect their secret sauce from distillation.

Ah, I don't follow him directly so I only ever hear about the computer-related stuff.
Gracana··on Commodore Releases Flip Phone
I'm at my computer now and I took a second look, and honestly that beige edition is damn good nostalgia bait. I still find it to be an odd direction to go, but it does look very good for what it is.
Gracana··on Commodore Releases Flip Phone
Retrocomputing Roundtable has talked about the new Commodore company over the course of a couple episodes, and I thought they brought up a good point about “what is it that people actually want from Commodore,” and the best answer they came up with is “to be 12 again.”

A new C64 with modern video output, a disk emulator, a SID chip replacement so you don’t need an original… that’s all good, but beyond that, it’s hard to say. This phone, though? I don’t think anyone saw that coming, and I don’t see how this could possibly be the right move.

Gracana··on Mercedes‑Benz starts large‑scale production of electric axial flux motor
Kind of orthogonal. Traditional AWD and part-time 4WD systems are solutions to get power from a single motor to both the front and rear of a vehicle. AWD has a center differential to account for differences in front and rear driveshaft speeds when driving on high-traction surfaces. 4WD just locks the front and rear driveshaft rotation together, which is a simple and robust solution that only works on loose surfaces.

With separate front and rear electric motors, there's no center differential to worry about, and a sufficiently sophisticated motor control system can make it behave well on and off road.

Gracana··on Nvidia Cosmos 3
Interesting! Yeah, that's quite expensive. For some reason I was thinking some of the useful cobots I had seen in the past were in the $10k range, but from a brief look around, that doesn't seem to be the case.

I have the GPU but no robot. What’s the minimum viable robot needed to play with this?

Yeah. Not linking as an endorsement -- I do think it's cool, but it's not worth it for that price.

Gracana··on I put a datacenter GPU in my gaming PC
An additional complication is that MI250Xes are two GPUs in one package, so you need to connect the first and last x16 SERDES groups to the host, otherwise you'll only see one GPU (or it won't work at all, idk).

Also, the cheap HPE pulls on eBay need some proprietary HPE magic to work, and I have yet to see anyone figure that out.

Second best in my opinion. Interstella 5555 is a masterpiece.

Do you mean in practice, or something? DP definitely supports HDR, and it seems to work fine for me.

It's not hypocrisy when different people do different things.

Gracana··on CARA 2.0 – “I Built a Better Robot Dog”
That’s how industrial VFDs do motor overload protection, they just keep track of heat accumulation (based on current) vs dissipation (based on fan speed) and fault when a threshold is reached. Probably there’s more nuance to it, but that’s the gist of it.
Gracana··on How OpenAI delivers low-latency voice AI at scale
Seems like there's a big risk of having that habit leak into human conversation. A lot of people try really hard to train themselves not to add those fillers.
