Agreed. This is all stuff that at MOST should be accessible over the LAN. The ESP32 is cheap and provides the WiFi and enough power to run a simple RESTful web app. If I actually need/want to access it remotely, it'll be through a well protected integrated web servie on a jump box.
A cheaper manufacturer could probably make the ESP32 do double duty as the primary micro-controller with a suitable interrupt routine.
The situation was worse than I thought. According to the AAIB report, they tested the material and found the glass transition temperature to be about 53C, so the jackass printed it in PLA.
Also, since it's Poly Lactic Acid, our metabolism is already well equipped to deal with the breakdown product.
It's great for things that will be indoors at room temperature. I made a snap-on camera mount for my monitor that has held up great. But if it was a dash mount, it would need to be PETG or CF-PA6 to not sag in the summer.
You might call it a tad goofy to turn a somewhat b-movie "hero" into a high quality bronze statue and place it in public display, but this was entirely a private initiative and it's standing in a commercial property and the owners where in on the fun. That's how stuff like this (and weird woke projects) should be done.
I get the joke - RoboCop was also a commentary on the derelict state of Detroit - and would pay the statue a visit.
Getting their jobs sent to American AI won't be noticeably better for American workers than getting their jobs sent to Chinese AIs.
According to an AAIB Field Investigation report (pg. 4), two samples from the intake were tested and found to have a glass transition temperature of 54.0C and 52.8C
So some idiot printed them in PLA. PLA is great but is very much NOT temperature resistant. It has been known to sag in a hot car.
Now look at the ratio of human driven cars vs. Waymo cars.
The problem was using a cheap substitute part. I'm guessing an injection molded ABS part would also have failed in that scenario.
CF-ABS is NOT like fiberglass at all. The CF is chopped into fine bits. They lend some stiffness at room temperature but not strength to the part. Certainly the carbon fiber bits don't lend any heat resistance.
That's why I suggest a mitigation to the increases for industry based on local employment. Data centers employ very few people per-Killowatt and so contribute a lot less to the local economy compared to those other industries.
It would make sense in conjunction with an employment based mitigation. Data centers employ very few people once operational (they're not called lights-out facilities for nothing), so no mitigation. Major manufacturer provides many steady jobs, more mitigation for them.
Of course, things get complicated. There are mini data centers being set up in people's back yards where the waste heat warms the home owners house. That doesn't employ a lot of people but gets effectively double use of the energy for at least a good part of the year, offsetting other energy use, so it should see some form of mitigation as well.
The bigger question though is how long until the data centers are abandoned? The big AI companies and their investors are operating at a loss as they jocky for market share and train ever larger models. But will people actually find the AI useful enough to pay for it once the investors start demanding their ROI? Will managers come to realize that they might be better off hiring people suffering schizophrenia with frequent psychotic episodes?
End to end encryption, for a toilet? Frankny I do not want a TOILET to connect me "end-to-end" with anybody. They're doing it wrong.
Time to pull up the sheet on IOT. Not only has it gone up it's own backside, now it's trying to go up ours too.
How about "hit", the most common word used to express the concept.
... is that it's a protocol designed and built by someone who knew what he was doing (Linus Torwalds) resulting, among other things, in the fact that migrating your upstream Git repo away from a commercial service like Github takes something like 20 seconds, if you're having a slow day.
Git is one of those things that bring the genius of well planned and built software to full display.
BTW, if you want to host your own web-interfaces upstream repo, Gitea is a very neat open source software for doing exactly that.
How many weeks are there in a light year?
