Not necessarily. Servers serving the model likely has enough traffic that they are batching decodes already. MTP reduces latency and increase efficiency only when the server can’t batch enough concurrent streams to be compute bound rather than memory bound.

Running the mxfp4 unsloth quant of qwen3.5-397b-a17b, I get 40 tps prefill, 20tps decode.

Funny, when I got tired of trying to find a nice desktop background I just started using a solid color of muted blue or green. I never read about this specific usage of colors before but I bet I saw something somewhere that clued me in on this color.

New comment by ydj in "Why I love NixOS"

I tried fedora silverblue for a while, but the way it works is that it builds a new root fs image whenever you change the installed packages, this makes system package changes take comparatively long vs a traditional os. They suggest installing most apps via flatpak, which is okay as long as you can deal with flatpak idiosyncrasies.

I also tried fedora coreos for a vm + container host, but found the recommended method to configure the system with ignition files and one shot systemd units to be too involved for making a one off system, and it’s probably better for a cloud deployment with many identical nodes.

New comment by ydj in "What Python’s asyncio primitives get wrong about shared state"

ydj — Thu, 05 Mar 2026 03:35:28 +0000

I think it’s not so much that the asyncio primitives got wrong about shared state, as much as is what the authors got wrong about the usage of those primitives. They are classic concurrency primitives that’s been around for almost half a century. They work as designed, but require some care to use correctly.

I noticed requests that were exploiting the vulnerability were turning into timeouts pretty much immediately after rolling out the patch. I’m surprised it took so long for it to be announced.

Is there a mypy plugin or other tool to check this via static analysis before runtime? To my knowledge jaxtyping can only be checked at runtime.

I’ve also done a noctua fan replacement on my ups. My worry is that they are rated for lower airflow than the original fans they replaced. Have you checked whether it stays cool when running on battery?

I had the same thought, and looked specifically for this in the paper. They do have a section where they talk about fine tuning with “cold” versions of the responses and comparing it with the fine tuned “warm” versions. They found that the “cold” fine tune performed as good or better than the base model, while the warm version performed worse.

But the author doesn’t give a single example, and so there’s nothing someone else can do to explain why or continue the conversation. The best we got use that he has a vague sense of unease, which I don’t think is very useful.

New comment by ydj in "The APL Challenge"

ydj — Wed, 05 Feb 2025 04:35:55 +0000

I think the facilities for building larger applications are lacking in APL. It would be great as something embedded into other languages. Consider something like numpy’s einsum, but using apl expressions instead. Use APL to express what it’s good at, and use the facilities of the host language to put together bigger systems.

I bought one of these to play with xcp-ng, but I didn’t do enough research or I’d have known that there’s problems with jasper lake, and they won’t have a working release till end of year.

This is neat. I had a similar idea of tracking what we read online in the browser. In addition to just recording time spent and links followed, I would also archive every article read to automatically build up a personal library of the articles themselves. Additionally, light weight note taking on the articles themselves ala hypothe.is

Unfortunately a new baby has drained all my time for such pursuits.

Hope you develop your concept further!

How does this compare to neutralino (https://github.com/neutralinojs/neutralinojs)

At first glance it’s the same idea but with more APIs to native functionality.

I’ve bought a uni USB-c to DisplayPort cable before. Support was helpful: had some trouble getting it to work with my laptop in Linux and they sent me another cable to make sure it wasn’t a cable issue.

New comment by ydj in "Study: Tesla Autopilot misleading, overestimated more than similar technology"

ydj — Fri, 21 Jun 2019 21:59:17 +0000

I see the use of “autopilot” name bring brought up a lot. Thinking about what an autopilot in an airplane does, labeling Tesla’s system autopilot is actually pretty apt.

It’s unfortunate that there’s a disconnect between what autopilot means colloquially vs what it actually does on a plane.

I wonder if it would be more intuitive to display a projection of the 4D scene in 3 dimensions (then projected onto a 2d screen), rather than a 3D cross section of the 4D scene.
