amarshall··on Dutch governments builds alternative for Microsoft based on NixOS
Use nixos-unstable-small branch or backport the change and build yourself.
amarshall··on DaVinci Resolve 21.1
H.264 is supported on Linux in DR Studio, it’s just not in the free version.
amarshall··on Sort branches by last commit date
I rarely care about the date of the commit on the branch to determine recency, I care about when I last switched to the branch.

This comment gets it correct https://news.ycombinator.com/item?id=49504860

I wrote my own version to do this nearly 10 years ago: https://github.com/amarshall/git-recent-branches

amarshall··on Arbitrary code execution in QubesOS via copy-to-VM error reporting backchannel
Qubes uses VMs, Jails use a shared kernel. So I wouldn’t say Jails are safer nor that they have a smaller exposed area with regard to host isolation than VMs.
amarshall··on FreeCORE TrueNAS Core – Continued
Bigger issue was that native encryption doesn’t (didn’t?) have a maintainer, so even though most bugs got fixed, it’s not a great thing to build on. Some of the key storage is also a bit outdated.

IMO use LUKS unless you really need the features of ZFS native enc.

amarshall··on The August 17 outage
Has it? Most of the LLM-generated commit messages and PR descriptions I read are needlessly verbose and miss the point: elucidating the why of a change rather than the what. If I actually pose a question based on them the author often tells me “yea that was some AI generated nonsense, I rewrote it now”.
amarshall··on Kimi Linear: An Expressive, Efficient Attention Architecture (2025)
Use uBlock Origin and add custom filters to block scripts on http:// ; e.g.

    http://$inline-script,domain=~localhost
    http://$script,domain=~localhost
amarshall··on Moonshine: Lets you stream games from your PC to any device running Moonlight
It’s possible to make a fake display to avoid that; both Linux and Windows have this ability. No dummy plug is required (though it is simpler than software solutions).
amarshall··on How we run Firecracker VMs inside EC2 and start browsers in less than 1s
Pretty light on details, heavy on fluff. 9.8s to 3.1s was userfaultd + hugepages, 500ms was PS/2 mouse and… where is the rest of the time to get to 400ms?
amarshall··on Ask HN: Has anyone replaced Claude/GPT with a local model for daily coding?
No, and having that is not required to know output speed nor the effect of thinking, so I don’t see the point in such a superfluous, indirect question.

As for the question you’re likely asking: benchmarks that include speed across many models and providers available at various places e.g. https://artificialanalysis.ai/leaderboards/models

amarshall··on Ask HN: Has anyone replaced Claude/GPT with a local model for daily coding?
Thinking doesn’t change output speed. Anthropic’s models are ~ 40–60 t/s median output speed.

Can take the geometric mean of total and active parameters of MoE to get approximate equivalent quality to dense model params. So sqrt(35*10)≈18.7.

The trade-off of MoE is that it is worse but faster for the same total size.

What context length and kv cache quant (if any) are you using? And MTP?
amarshall··on Linux Terminal Memory Usage
Probably want `kitty --single-instance` to reduce memory usage when opening multiple.

amarshall··on Group averages obscure how an individual's brain controls behavior: study
The actual paper (linked in another comment here) is literally titled “Nonergodicity and Simpson’s paradox in neurocognitive dynamics of cognitive control”. Why they omit it from the blog post version, I’ve no idea.
amarshall··on Group averages obscure how an individual's brain controls behavior: study
Seems like a case of Simpson’s Paradox https://en.wikipedia.org/wiki/Simpson%27s_paradox
amarshall··on Google releases Gemma 4 open models
If you are running on 4090 and get 5 t/s, then you exceeded your VRAM and are offloading to the CPU (or there is some other serious perf. issue)
amarshall··on Tinybox – A powerful computer for deep learning
Oh I missed the "quad" before 3090.
amarshall··on Tinybox – A powerful computer for deep learning
You're almost certainly (definitely, in fact) confusing the 120b and 20b models.
amarshall··on Apple Studio Display and Studio Display XDR
Yes. Even 90 Hz is a noticeable improvement over 60 Hz. I wouldn’t pick it over high-DPI, though.
amarshall··on Bluetooth Headphone Jacking: A Key to Your Phone [video]
No, the connector is longer than it is tall.
amarshall··on Bluetooth Headphone Jacking: A Key to Your Phone [video]
Maybe, but Apple doesn’t make them thinner anyway so the argument is invalid. iPhone 6S with headphone jack: 7.1mm thick. iPhone 17 is 7.95mm thick.
amarshall··on YouTube caught making AI-edits to videos and adding misleading AI summaries
It’s easier than that. Replace shorts with watch in the URL.
amarshall··on Cognitive and mental health correlates of short-form video use
Non-Shorts can be vertical as well. It works fine, and without the swipe-encouraging UX. If they were “just making long/medium-form videos in portrait now” they don’t need YT Shorts to do that.
amarshall··on Asus Announces October Availability of ProArt Display 8K PA32KCX
DisplayPort 2.1 (which the monitor supports) provides sufficient bandwidth for 7680x4320@60 Hz 10-bit without DSC when using UHBR20. The press release unfortunately doesn’t clarify whether the monitor supports UHBR20 or only the lower UHBR10 or UHBR13.5 speeds. Of course, the GPU must also support that (Nvidia RTX 5000 only at the moment, as I believe AMD RX 9000 is only UHBR13.5).
amarshall··on Shai-Hulud malware attack: Tinycolor and over 40 NPM packages compromised
Redownloading everything isn’t a risk when the lock file contains a hash of the download on first update.
amarshall··on macOS Tahoe
Enabling Reduce Transparency is a sure-fire way to find a dozen bugs within a few hours. It is always quite apparent no one who is empowered tests it at Apple. At least the padding issue is the one Feedback report I sent that got the “more than 10 similar issues” label so it may actual get fixed.
amarshall··on macOS Tahoe
> SO much padding

No idea on macOS, but turn on Reduce Transparency on iOS and there’s tons of padding most of the time, but then sometimes zero padding. And I mean zero. The edges of buttons and text are at the edge of the underlying background. It’s…embarrassing.

amarshall··on iPhone Air
As an iPhone Mini owner, I have not experienced any poor or broken UX in apps, but ofc I am n=1.
amarshall··on GPT-OSS-120B runs on just 8GB VRAM & 64GB+ system RAM
> I'd have to spend thousands to get that setup

Can be had for under US$1000 new https://pcpartpicker.com/list/WnDzTM. Used would be even less (and perhaps better, especially the GPU).
