walrus01··on H.264 Is Magic (2016)
If you really want to see magic, take a test sample of YUV420 video and AV1 encode it to an extremely low bitrate at like 720p, 24 fps to simulate something like the jerky handheld front-phone-cam in the example URL. Keep lowering the bitrate until the quality become unacceptable. Then compare it to the same bitrate/approx total file size in H264 and how bad it looks.
walrus01··on CVE-2026-98432: Linux TCP Use-After-Free Risk and Patch Validation
It would have been about 50x less annoying if whoever was driving the LLM had simply told it to make a clickable top of page index/headers in markdown and divide it into sections and subsections by logical topic.

walrus01··on CVE-2026-98432: Linux TCP Use-After-Free Risk and Patch Validation
The overlaid HTML popup on that page for "Try The World's First Agentic AI Hacker." tool is cancerous and annoying. This should really be a link to a more reputable link for the CVE in question.

It doesn't appear until you've read the page for maybe 10-15 seconds, so if you're not seeing it, just wait.

It even managed to get past ublock origin, since there's no specific rule for it yet.

There's many EU companies that want to have a contractual relationship with only another EU company and be absolutely assured that the models, the contents of the KV cache, any logging, all access control/credential systems, billing platform, etc are all hosted on EU-company owned hardware located in an EU jurisdiction.

There is a similar thing happening now on a smaller scale for Canadian companies that want to migrate off USA-based platforms for all sorts of SaaS and reasons.

> The Post is not exactly top notch journalism.

I'll go as far as to say it's a right wing agitation propaganda rag. But the story first appeared in the NY Times, as another commenter has linked here,, so it's possible that the story may be accurate (though undoubtedly the nypost has sensationalized it, as that's their specialty), but both things can be true simultaneously. The NY Post can be trash and this series of events might have really happened.

walrus01··on US agency approves Amazon Leo’s $11.5B acquisition of Globalstar
This is an incredibly inaccurate and uninformed description. Globalstar was a failure in the market because its satellite network is bent pipe and doesn't provide open ocean or polar or true global coverage. The second corporate incarnation of Iridium (that bought it out of the bankruptcy process) was wildly successful with maritime, aviation and DoD customers. Iridium had VASTLY more market share in portable LEO satellite terminal users and revenue at the time of this acquisition. Iridium grew its market to include embedded data modems like the Iridium SBD modems you find in Garmin Inreach and tons of other equipment.

The *ONLY VALUE* of Globalstar for an acquisition is its legacy spectrum allocation in a very valuable (sub 1.7 GHz, above 1.2 GHz) range. The technology was utter crap compared to Iridium and nobody who worked in two way satellite has taken it seriously since maybe 2002.

> I've always wondered why we haven't seen a broad architectural movement returning to highly ornate decorative facades

If you follow trends in USA single family detached home construction, the trend is rather the opposite direction. Extreme rises in inflation generally, price of vehicles, construction materials are sending house builders down paths of using the cheapest, shoddiest possible materials and then slapping a veneer of normalcy on top of it. The amount of MDF and oriented strand board in use is greater than it's ever been. Now they're going back to aluminum wiring, copper clad aluminum cat5e cable, and similar. You should see the horrific results of a framing inspection (pre-drywall) done by a professional, neutral and diligent inspector in the average single family home tract development these days.

Modern "Architecture" has taken the trends of the mid-late 1990s McManson to its ultimate extreme of building "luxury" housing that is in reality anything but. Just good enough to sell, then the shoddiness in construction and maintenance becomes somebody else's problem.

walrus01··on Why is this fingerprinting script creating bioweapons?
yeah, it would be good if the commenter (if they've never before tripped the no LLM generated text guardrail) could get some kind of warning like "don't do that, and here's why..."
walrus01··on Why is this fingerprinting script creating bioweapons?
yes, search models on huggingface for model name containing "abliterated"
walrus01··on Why is this fingerprinting script creating bioweapons?
I think we can do without people pasting llm generated output into the body of an LLM comment, if people need to provide it for some example, they can do it via a one of the services like https://pastes.io and an outbound link with appropriate description.

walrus01··on Raspberry Pi Zero 3W and Pi 4 Model A spotted in device trees
how close is the OS distribution for that to actual stock debian?
walrus01··on Raspberry Pi Zero 3W and Pi 4 Model A spotted in device trees
The biggest thing I want to see in a zero 3 w is not better cpu or ram, but wifi that isn't the zero 2 w spec of "2.4GHz 802.11 b/g/n wireless LAN"

Having at least 1x1 802.11ac that's capable of working in the 5050 to 5900 MHz band will be a huge feature improvement. Such as to connect to a 'modern' AP running in an 80 MHz channel.

There's tons of environments where 2.4 GHz is a CSMA hell of noise and the performance in a single 20 MHz channel will always be crap, and ranges/real world distances between AP and pi will be very limited because of the extreme noise in the 2.4 band.

walrus01··on Survival LLM: AI assistant and emergency library that runs on your own computer
If you're actually offline and need information in a 'survival' situation, I'm not so sure the hallucinatory nature of an LLM is the based way to distribute a repository of information. Additionally, there's no need to fit an LLM entirely in memory.

In a theoretical scenario where the internet is gone and isn't coming back: If you can deal with a very low token/second rate there's no reason not to store 'offline' a much larger model like qwen 3.8-flash-next or deepseek v4 flash 1017 and use an inference engine which can stream-read it off disk to extract the information you want, albeit slowly. Of course also download and use things that'll fit in RAM, sure, like the qwen 3.8 27B in the linked page. But no need to restrict yourself to only smaller models.

walrus01··on Eunice is almost here
It depends on what range of the years 1981-1984 we're talking about, but yes, it was very costly. Not that a full IBM PC would necessarily be required to write a novel. People were writing whole books on less expensive CP/M based systems with like two 160KB floppy drives. One to boot and run the word processor software from and one for data file storage.

I have a family member who bought an Osborne Portable for something like $1800 1981 money, an inflation calculator says that would be the equivalent of $6,971.17 today.

walrus01··on Eunice is almost here
It wasn't that he didn't like computers at the time, he didn't have money for a proper word processing setup. Something good enough to write a full length novel on in 1981 with a printer and the commercial word processing software would have been the equivalent of $3500-4500 or more in today's money adjusted for inflation.

the advertising industry in general is a plague on a great many things, in the current instance of late stage capitalism we exist in.

I'm banned from /r/domains/ for daring to question the land rush of speculators buying .SI "Super Intelligence" domains and trying to resell them to the die hard true believers of a certain political figure. No great loss. If you ever want to see a subreddit that makes bitcoin true believers look like rational, sane individuals...

walrus01··on OpenShell – A safe, private runtime for fleets of autonomous AI agents
In my case it's a fairly boring proxmox server. The KVM VM started as a bare bones debian install and then I added xorg and xfce4 and the tiger vnc server. I have a GUI on it for when I want to use it that way (in screen dimensions that are a 1:1 mapping of the native resolution of my laptop for full screen VNC session), or of course I also talk to it by regular SSH session, and screen or tmux. The VNC server listens on 127.0.0.1:5901 and then I use SSH port forwarding from my workstation machine to connect the macos tigervnc client.

For people who don't want to do it with proxmox you can also do the same with manual KVM command line tools (virsh, etc) with no GUI. Or as something like a Xen dom0 running the guest as a xen HVM or PVH guest. Lots of ways to do it.

If I need to move it I can shutdown the VM and take an image of its LVM logical volume storage device (by something as rudimentary as like dd into an xz file), move the file, then create a new identically sized logical volume and do the reverse using dd to write from the file into the LVM logical volume location on the destination.

Edit: It would also be possible to do this all in one machine by something as basic as running virtualbox on your laptop, make a disk image file, installing the VM in that, give it bridge mode access to the physical network adapter to get its own DHCP lease in your same LAN segment, and treat it as a logically separate computer. There's minor risks of theoretical hypervisor escapes from the VM on the same machine, but such things tend to get patched fairly quick.

I don't personally care about betting sites but it's the legal precedent and principle that the government can add anything to such a list and make obligatory.

That's certainly a valid risk, if I were to put myself physically at the mercy of Turkish armed law enforcement inside their borders. In my particular case there's no public information that links my real name to the hosting company, as my work is behind the scenes.

Could Turkish intelligence link me to the company if they spent significant resources researching the hosting company that provides services to their political enemies? Probably. Do I have any personal plans to take a vacation in Turkey any time soon, or a pressing need to visit Turkey? No.

I am pretty sure we also have someone, somewhere hosting something that insults the King of Thailand, so I suppose that's a risk too.

walrus01··on Quad9 to exit France
As a side project I help out with some technical stuff at a hosting company that provides services to a political group that is strongly anti Erdogan. The infrastructure is in the USA.

We do not block IP traffic from known Turkish ISP ranges. The customer (the political group) receives all sorts of dire legal warnings and threats that what they publish is contrary to Turkish law.

None of our other hosting platforms are configured to block any traffic to/from Turkish IP ranges. We have no business presence or financial involvement with anything domestically in Turkey. Am I subject to Turkish jurisdiction? I don't think so.

But by what you wrote, I am providing services in Turkey.

walrus01··on OpenShell – A safe, private runtime for fleets of autonomous AI agents
As an example I run opencode and anything related agent-related in its own dedicated KVM VM with its own LVM logical volumes for storage on a headless server. This has no access whatsoever to the personal data that lives on my laptop and workstation desktop PC. The VM gets periodically imaged and backed up, and is relatively easy to move between host machines if I need to.

One benefit of doing this is that I can leave it doing long term slow things with slow but capable LLMs on a truly 24x7 basis without worrying about it being interrupted by a laptop being closed/going to sleep, or workstation level software updates/reboots on my primary desktop PC.

I recall seeing something about that. I don't know of anyone still using such an ancient model when much newer Qwen 3.5-120, 3.6-35B-A3B, 3.8-27B and 3.8-flash-next all exist and score much higher on all conceivable metrics. I would like to see if anyone can replicate the same thing on a 'current' Qwen released in the past 6 months.
