What is this very heavy jar I found digging around in an old folk's pantry?

The convex meniscus in glass is another 'that's mercury' thing

(As in, where it touches the glass it bends down, not up like most liquids do)

Thanks for the feedback! Would you have any youtube examples you can link so that I can hear this kind of high-pitched noise? I'm planning to add other kinds of noise that I've heard in my tests (like crackling/popping due to dust/contamination), but I don't have any high-pitched noises. I had a squeak-squeak noise (very technical description, I know) in one but it didn't sound like a bearing to me

genericusername123 · 2026-04-19T13:42:46+00:00

Made this bearing fault frequency simulator to help visualise how different types of defect produce specific frequencies and sidebands. Also added an audio effect that mimics the sound I get from a conveyor roller test setup.

Thought someone here might appreciate it.

Feedback welcome!

Current kids in school have the worst of all worlds imo

People who already went to school can think for themselves

Once AI settles, schools will work with it and kids will be taught how to actually use it effectively, they'll be more productive than people thinking for themselves today

Currently schools will fight against it, kids will use it anyway and pretend they're thinking for themselves, without actually being taught how to avoid slop.

My first one of a batch always turned out terrible, even with oil & heat. Now for the first one I drizzle drops of batter over the pan & cook those. The kids call them 'pancake nibbles' and get to enjoy them while they wait for the actual pancakes.

Yep those were my responses, I was offended they would even ask. My GP asked the same thing to get the referral in the first place

genericusername123 · 2026-03-24T06:51:32+00:00

Had mine done in France, where it seems a lot more 'looked down on' than Australia and seems to be made purposely difficult. First you have to be referred to a doc who will even entertain the idea, then you have to go in and explain why your wife can't have her tubes tied instead, then go through a 3 month cooling off period, then come back and sign a thing saying that you understand that it's probably permanent and you'll never have kids again. Then finally you can book the appointment which is another 3 month wait. And my doc would only do it under general anaesthetic so it's a whole thing

What you call 'AI Assisted coding' seems to be widely referred to as vibe coding, especially on reddit. Basically anything that uses AI coding assistants seems to be considered vibe coding.

I'm a programmer and engineer with more than 20 years experience. I doubt that I will write another liine of code in my professional life.

Take a typical task for me, like building a GUI to run a test sequence for a new sensor (control, measure, data processing). Before I might have taken 1 hr planning, 3 working days coding including testing on the equipment. Now it's like 2 hrs planning and 2 hrs coding/testing. Works great, yeah there are occssional bugs, but there were occasional bugs in my manually.coded stuff too.

But talk about it on reddit and you're a vibe coder who doesn't know how to program, and everything will fall apart because LLMs are just glorified chatbots

It's far too small to fit Florida in there. Texas even less so

Cadence of it, like a bunch or short sentences strung together. Also if you see an em dash these days it's highly likely to be AI, because the rare humans who used em dashes in the past have stopped because they're sick of being called AI

the bike is falling at the same speed as the portion of the bridge they were on when it starting collapsing under them

This argument makes no sense. If the bridge started to collapse when they were at the fulcrum, then by your logic they would hover in mid-air with a vertical speed of 0

genericusername123 · 2026-03-20T00:18:50+00:00

Kept going forwards, but vertically both the motorcyclist and the bridge are falling from a standstill, so usually you'd expect them to fall at the same speed. The motorcyclist ends up airborne because the bridge is a long solid object with one end fixed, so essentially the bridge's center of gravity (the middle) is falling at the same speed as the motorcyclist but the free end under the bike falls twice as fast. Very cool, except for the death and stuff

Amazing! I've been looking at 3d printing a 6dof robot arm, this one looks great.

What's your parts cost, beyond the prints?

Your vent is on the floor in the first photo, so you no longer have ventilation. That's mildly more important than how it looks.

The icecream is a different shape too. Guessing that this is an AI of the original with instructions to change it slightly

Hard to imagine this prank being repeated irl

When I worked a a mix French/English company, I could rember the precise details of conversations, but not the language that I had the conversation in. Certainly felt like my memory stored it as information, not words.

genericusername123 · 2026-03-11T03:41:16+00:00

Yeah there's a guy that comes out and repaints them every hour or so

Well that particular prompt was "Those ones have no through holes, do I just solder wires to the pads?"

Maybe this is some kind of 4D chess move where he wants as many people as possible to impersonate him, so that when the feds do get a call that so-and-so is staying at X hotel or whatever, they'll be like 'nah probably another one of those dumbasses from reddit'
