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.
Am I the only person on the planet who still opens the garage door with, you know, my hands? Is that completely crazy? Am *I* crazy?
Around my neighborhood almost no one parks in the garage (they park in their driveway, or the street). The garage is where you store stuff (and you rarely open the garage door).
I thought the garage was where people put their guest bedroom.
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.
That was the only pad Russia had which has the infrastructure necessary to launch humans into space
Not entirely correct. It is the only *active* pad with that infrastructure. There are decommissioned pads that have been used for manned missions in the past. What state they are currently in is an unknown, but it has been speculated that equipment could be salvaged from them to repair the damaged pad.
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.
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.
... except instead of shoes becoming the only profitable product to manufacture, it's chatbots. Nobody knows why, but when it's all over, the only survivors will be those who evolved into computer-illiterate deaf-mutes.
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?
Russia doesn't have the ability for manned spaceflight. ergo they don't have cosmonauts any more.
Tell that to the folks on ISS who ride back and forth on Soyuz all the time. A couple of people went up to ISS from Russia just one week ago.
To be fair, at the moment, future ISS launches from Russia won't be possible because of some launch pad damage incurred by a recent launch, but Russia still has the capability of launching crewed rockets into space from other pads. They just can't send any to ISS right now because its orbital inclination is incompatible with the locations of those other pads while staying within the fuel capacity limits of their rockets.
