  • Yeah, the protocol itself is pretty robust. The cable I had didn’t have enough noise immunity for the dirty power the building had in India (afternoon brown outs when the voltage dipped when the air conditioners ran). The Faraday cage that I made around the cable helped with the noise and also (and I believe more crucially though I had no scope to confirm) gave the two boards a common ground. I had a little trouble with before I left, but it didn’t work at all in India until I modded it. Made the hardware engineer buy me a beer when I got back.



  • I once took a really crappy RS232 cable to India as part of some equipment to train our remote developers. The cable barely worked in our lab in the States. I told our hardware engineer that it wasn’t going to work in India, and I was right. So in India I ended up having to wrap the entire wire bundle in a wire that I soldered to ground on both sides. Soldered it together with a plumbing soldering iron. I am a software engineer, but I have an electrical engineering degree. The VP that I was traveling with couldn’t believe that the crap I made worked. Realistically, I couldn’t either.




  • I imagine that is what the market will bear. The big problem is likely other cars available in that market. At least in my market, there are many EVs with lower than average mileage and this one is the opposite end of the spectrum. Also, the Ioniq 6 has polarizing styling which limits the potential buyer pool further.

    A better analysis would probably be a sample of a bunch of EVs in multiple markets rather than cherry picking a particularly egregious example. I have bought two different used EVs to take advantage of the depreciation, so I don’t think the thesis is incorrect. Some of the depreciation was due to the tax credit being claimed and unavailable for the second owner.


  • I intend to be retired for Y2038. I have been warning my younger coworkers that 1. they’re going to have to fix it, 2. It’s going to be worse than Y2K, and 3. Managers and up are not going to take it seriously because Y2K was mostly a nothing burger (because of a lot of hard work and investment that people forget about).


  • My issues are not install, but uninstall. Why do I have so much crap installed? I used it on a project once 7 years ago and haven’t since. Why not uninstall it? It is useful, just not currently. It took less than a minute to install when you installed it the first time and your connection is faster now? But what if the archive goes down or it is retired or obsolete? It is small, keep it!

    Turns out lots of small adds up to big.
