I'm a SWE working on something completely different by day but tinkering with several other side projects, including this, https://github.com/ratsbane/panda-mcp/ (which is accelerating my computer vision learning rapidly) I'm interested in your choice of the OAK cameras because I'm trying to select a camera model also. I started this with a simple USB webcam and added a PhotoNeo camera. I've just switched to RealSense and I've got a couple of ZED cameras on order but now I'm looking at the OAK-D and thinking that it makes a lot of sense to run a nn directly on the camera.

I started this over the summer when I was moving to a new house and wanted to document the family history behind some thing I own. It's turned out to be more useful than I thought and I've expanded the features as friends found it useful. A developer friend, who I used to work with, joined me and we're both working on it now. It does have a little revenue now but we are far from quitting our day jobs.

I'd really like any feedback from the HN community!

They can be both a joy and a connection with the past as well as a burden.

And because of that, I started building this website https://provenancevault.com/treasures/discover (it's probably not ready to introduce widely yet, but relevant to this conversation)

Also the LeRobot reference arm (SO-ARM100) is 6DoF, but it's very hackable and there are already project with different grippers, etc.

You can build the reference arm easily and cheaply and the software is designed to train AI. There's a lot to explore and extend there and the community is growing rapidly. It's based on the Stanford Aloha project. https://huggingface.co/lerobot

Specifically, what? I've been asking myself this since at least 2016 and I'm sure many other people have too. I've made phone calls, donated money, volunteered for campaigns and gone door-to-door. None of that has made any difference. The problem is in figuring out WHAT to do.

He's really good; close to retirement age and very methodical and thorough and his prices are reasonable. The electrician I use also drives some sort of van. I've had a few other contractors out for different projects around the house and I'm starting to notice a correlation: the ones in the giant lifted pickup trucks are unreliable and overpriced; the ones who drive vans are the best.

At the very least it seems like something to keep lawyers busy for a long time, unless everyone can ctrl-z back to Thursday. I am thinking though that this is a risk of IP-sharing arrangements - if you can't stop the employees from jumping ship, they're dangerous

We haven't had 45,000 since 1989; 54,000 in 1972. The rate has been steadily decreasing (with a few ups and downs along the way) for about the last 50 years(1), even though miles driven has been steadily increasing(2). This is because we, as a society, as a government, decided to study the problem and implement changes to improve the situation.

If we adopt the rule that the next person to be served is the most recent person to join line, it's inevitable that a second line will form with people waiting to go to the first line and if someone tries to go to bypass the second line and go directly to the first line, the crowd in the first line will direct their rage at this person and compel him or her to queue in the second line - it's just as if there were only one line and the person had cut in that.

I walked around the US embassy one day. The weather was sunny but cold and windy; the embassy is on the Malecón, the seafront that stretches around Havana, and waves were crashing over the walls. It was unpleasant. I had never heard of the "Havana Syndrome" thing then, but in describing that day in my notes, I wrote that there was a feeling of pressure from the wind and sea spray. In hindsight, I wonder if this sort of weather condition contributed to perceptions of this syndrome. In videos I took that day you can sense this from the wind noise.
