I made a person seven years ago. They started out pretty useless, just eating and pooping and crying a lot. But now they can walk, talk, think, read, write, act, sing, and love.
I helped build “The Cloud” without really knowing it lol.. I joined a 5 year electrical apprenticeship after highschool. I spent many days between 2006 and 2012 building out crazy electrical systems in these giant warehouse looking buildings in Northern Virginia, for DuPont Fabros and Digital Reality. I had no idea exactly what the purpose of these server farms were for, but they just told us “if we build it they wil…
Goddamn that's pretty crazy

If I was an absolute beginner (which I am) I would be definitely very wary to do by myself the electrical wiring or the gas connections... while half-assing the rest can only look bad, those can kill you and your loved ones (neighbors need not apply).
Gas? Yes. Electric? Eh, if you are smart enough to program a computer, you are smart enough to read and learn how to do electric properly.
Being very smart, he was sure he was in the right, so I hear he fought with the city for years over it, in the meantime layering on his home-grown solar and biomass gasification generator. I'm not sure if he ever got back in compliance.
I would encourage anybody going this route to have early discussions with a licensed electrician. A lot of code compliance stuff is non-obvious. It's what you get when you start with smart people and then add a hundred years of experience.
Here's the clock's homepage, which has some pictures: https://vonnieda.org/tc18, and more pictures on Flickr: https://www.flickr.com/photos/vonnieda/sets/7215762293577593...
And a blog post that goes into excruciating detail about the entire process: https://vonnieda.org/archives/1406
I built a total of five of them. I sent one to the person who designed the enclosure, one to my brother, one to a friend, one to eBay for sale (which ended up in Germany), and kept one for myself. It still sits on my desk ticking along quite happily. I've changed the backup battery once in 14 years and have made little tweaks to the firmware over the years.

This joke is funny because no one currently living has to make this choice.
Oh they do, but now it's in the name of electrification . https://www.theguardian.com/environment/2021/jan/03/child-la...
A synthesizer played by pumping energy into it: https://www.youtube.com/watch?v=huYJa2Du57g Because the volume should track how hard you play and stopping to change/recharge batteries takes away the fun!

Am I understanding this correctly, basically a Colo was acquired by Amazon? It’s pedantic but colo existed for decades before AWS. It’s the software layer from AWS that made it “The Cloud” (quicker access to hardware & billing by the second, not month)
My understanding later on in my career shift to computer engineering was that Amazon is renting out the whole colo, and just owns their equipment.
Amazon isn’t maintaining the datacenter infrastructure such as cooling and power, but instead it’s covered in their bill.
This one is physical and digital. I personally patented, designed, built, and deployed a novel ultrasonic inspection device that encoded position/orientation using IR (Just like motion capture in movies). Actually used it in the field at a nuclear plant. The value pitch is that is allowed for fast deployment (manual scanning), but could also record coverage ensuring nothing was missed. Fast deployment was important t…
This is really interesting. Id love to hear more about it. Also agree quaternions are the worst. You should check out n-vectors. Solves most of the same problems and way easier to work with.
They still have the link apparently. The system used traditional manual scanning system with a VGA capture card on the back. I synced that with an off the shelf IR capture system and was able to record the ultrasonic scan into a video file using opencv. I would also record a USB cam at the same time as a sanity check. I could generate point clouds of data by reading the video file and the synced position data to project where the ultrasound was going and the linear response of the scanner. Was a ton of fun to develop and it was nice that I pretty much only had myself to blame when things went wrong. I also had to write the procedure for operation in case someone else had to use it.
