Comment Weird (Score -1, Troll) 41

Last weekend I gave an old iPhone 7 Plus to someone whose daughter needed it for a diabetes monitor app. I factory reset it and unlinked my Apple ID. When it powered back up it said it was now owned by 1*******@1*******. Definitely not me. Apple wouldnâ(TM)t help regain ownership even with the original sales receipt from 2017. So no app for the little girl and I have a brick phone.

We did this for a work project recently using a major automation supplier's software. Even with the most powerful Xeon+RadeonRTX machine we could buy, and a very simplified model, it took 100x real time to run. So I get why NV wants to go this direction.... it's not useful without extreme computing power.

The software is necessarily insanely complicated too and it took a team of high end of people to build (or worse, manage) the models. It was cool what it could do if you could figure out how to make it work though.

In the end we just scrapped it and asked for our money back. For what we were doing it would have been cheaper to rebuild the machines from scratch than screw around with the modeling.

Comment Inept company (Score 4, Interesting) 63

Spent a number of years working with this company. Mind boggling inept group of people and leadership. They spent $150 million on a bottle filling line I worked on that was outperformed by $2 million ones they already had. Management just couldnâ(TM)t understand that something poorly engineered wouldnâ(TM)t work no matter how much money they threw at it. In the end they moth balled it and hid the fact from their shareholders because it was too big to fail.

I was going back and forth with someone in a food thread. Obviously looking for retribution for me not agreeing with them, they went through my post history from a few weeks prior and reported a post. I got banned from *all of reddit*, not just the sub, for saying the temporary jeopardy host Mayim Bialik was ugly.

I remember doing this with MATLAB, Simulink and RTWorkshop a long time ago as a budding controls engineer in college. No bode plots or root locus plots though. It's a non-linear multi-variable state problem. Linearized differential equations generate a state matrix and then some closed loop matrix equations help solve it for you. The inverted balancing was actually pretty easy. The harder part was we made it swing up from the stable equilibrium (downward) position and catch and hold it in the unstable (inverted) equilibrium.

Ecobee should change their firmware to follow the schedule but with a +/- 30 second random schedule delay. That alone will smooth the peak out. If you google around you can find stories about how the power grid in the UK used to work with their TV networks to know the timing of commercial breaks for major sporting events. Hundreds of thousands of brits simultaneously turning on a 230V hot pot for tea water at the same time creates massive energy demand issues and you need to be ramping at the same time the load is going up, not trying to catch up to it.

I had many issues installing my 2 Ecobees but found their tech support to probably be some of the best I've ever experienced. But i think they were well practiced with a huge design flaw in the product - the internal temperature sensor is hugely influenced by the heat the own units gives off. So they are good at telling you how to work around it.
