  • 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.

    The most acceptable loss for the Freedumb to own guns? I saw plenty of things making fun of him. Even before his body fully hit the floor. My favorite was a package of fruit gushers that had been altered to say Kirk Gushers and had his face with a flow of liquid coming from the neck.
