VTimofeenko··on It takes 5 cloud services to hear my doorbell
Not exactly home gamer stuff, but there are devices like the Axis cameras which can push to a configured mqtt.

Generally ONVIF is the protocol one should be looking for in a camera, it indicates that the edge device can play ball with a central server (Frigate, Blue Iris, etc). Profile M specifies the metadata into external mqtt:

VTimofeenko··on Show HN: I made a Raspberry with Qwen my local car AI
From readme:

"""

Unverified against the real car — it will confirm or refute itself on the next drive

Looks like a ton of this is aspirational.

For your project -- do you really need the car's GPS positioning? Could go with a dedicated GPS antenna, like the freematics dongle

VTimofeenko··on Flock-style scanners now track WiFi/Bluetooth identity from devices in your car
"Right equipment" is probably very load bearing. Wouls need a very high gain directional antenna, not sure if a camera next to the road has the space to pick this up from a moving car.
VTimofeenko··on The most official water costs $120k a gallon
The argument for "it shouldn't" could be that it's a federal supplier and/or some sort of RnD exception. Not sure if NIST would even sell to a private buyer.
VTimofeenko··on The most official water costs $120k a gallon
Shows $508 for 2 cartons, so 254 per. NY has probably most expensive smokes, ranging $140-155 per carton
VTimofeenko··on Tailscale didn't stop the Hugging Face intrusion
You can use raw wireguard + ddns(if your ISP-given IP changes) to achieve this. This also implies maintaining a firewall to allow network pixies in and out. Totally doable, just needs a bit of upfront setup.

Benefit of Tailscale is that run the external servers that your PC and mobile use to establish connection.

Alternatives are Logmein Hamachi(might be dating myself here, haven't used them in 10+ years), Zerotier, Netbird. Headscale too.

That's your right, but the problem is that cameras are in public and some people do mind this.

This is probably PEBCAK, but I can't figure out how to capture an island
VTimofeenko··on Windows 11 users are tired of MS account requirements creeping into everything
I can totally see Internet availabilit correlating with the rise of unwanted stuff in the install. Believe it started with 3rd party games being part of the OS at first. I don't recall the yes/maybe later dialog "options" in win8 though, at least not in the beginning.

I actually really liked the win8 start menu change and the live tiles, even wrote some tiny homegrown apps with them. My logic was always "if I am opening the start menu, I will want to interact with that menu and only it until it's closed", so having it fullscreen made sense.

VTimofeenko··on Windows 11 users are tired of MS account requirements creeping into everything
Moving 15 years back puts you into glory Win7 days. IIRC, the spam started with win8 which was released ~13 years ago and was very mild at first
VTimofeenko··on Unified Controllable and Faithful Text-to-CAD Generation with LLMs
Same, I had reasonable success with LLM-generated OpenSCAD files fed into prusa slicer. Just needs a few manual tweaks for spatial transforms from time to time.
VTimofeenko··on It's hard to justify buying a Framework 12
How would one know though by just looking at the device? I have chassis that came with Intel 11th gen, but the brainboxery, keyboard, battery, touchpad -- all have been swapped over time.
VTimofeenko··on Toxic chemical leak at a manufacturing facility in Orange County
Maybe the thought process is that leak would effectively be pressure normalizing over a larger area and more gradually than creating a tiny hole, so whatever I said about jet ignition would not be applicable
VTimofeenko··on Toxic chemical leak at a manufacturing facility in Orange County
Shooting holes in pressurized vessels with explosive stuff is probably a very bad idea, as outlined in my comment[1]. Slowly loosening a valve is a better idea.

That being said, in no way, shape or form am I an authority on the subject.

VTimofeenko··on Toxic chemical leak at a manufacturing facility in Orange County
Quick googling sez that liquid nitrogen might solidify the MMA inside, turning it into even more of a pressure cooker
VTimofeenko··on Toxic chemical leak at a manufacturing facility in Orange County
IIUC, the stuff inside is polymerizing, turning into goop that gummed everything up. It was probably not goop when used for the original purpose

Inb4: I don't work in the industry, my knowledge is limited to a faint memory of a college course on fluid dynamics.

If I recall correctly, high pressure ignitable stuff can spontaneously turn !!FUN!! in absence of heat if it is suddenly relieved through a pinhole. Basically jet is followed by a ring-like zone where the stuff mixes with oxygen. Jet creates tiny zones of very high temp, thus igniting the mixture ring that follows.

VTimofeenko··on Chuck Norris has died
There is US exported media that just randomly becomes popular in a specific demographic. Case in point: Adventures of Ford Fairlane, a flick with Andrew Dice Clay that got a razzie the year it came out. IIRC it got a cult following in Norway because the voice over was done by a popular radio DJ.

WHOIS sez it was just registered, registrar is NameCheap. Uses Cloudflare DNS. .bot domain hosted on Vercel. There is a link to .ai domain with similar info.

Certificate transparency logs list everything as brand new.

Cursory glance at other Nvidia domains shows Safenames ltd as their registrar of choice.

Seems a bit sketchy

VTimofeenko··on Don't Trust the Salt: AI Summarization, Multilingual Safety, and LLM Guardrails
I usually use English to talk to Gemini, but the other day I wanted to try and find out the original band of a Siberian punk song that I have carried around in my music collection since time immemorial. Problem is the tags are all over the place in this genre and there are situations where "Foo-Bar" and "Foobar" are two completely different bands. Gemini was clearly trained on some genre forums from late 90s which are... shall I say non-PC by any stretch of the term.

In the middle of the conversation it randomly switched from English to Russian and clearly struggled to maintain the tone imposed by the built-in prompt.

VTimofeenko··on Tesla 'Robotaxi' adds 5 more crashes in Austin in a month – 4x worse than humans
Inb4: not remotely in the marine field, so a genuine question. Would it really make an impact?

Robotaxis market is much broader than the submersibles one, so the effect of consumers' irrationality would be much bigger there. I'd expect an average customer of the submarines market to do quite a bit more research on what they're getting into.

VTimofeenko··on AI agent opens a PR write a blogpost to shames the maintainer who closes it
Printers prey specifically on fear. When talking to them, gotta be polite but firm. No more than three threats during the conversation, and the threats have to be credible.
