I find it a bit grim that the word "Tesla" only appears once in this entire thread, despite 356 comments preceding me.
Have you ever hurt yourself from your own code?

#372I bet most robotics and other embedded people have :) . I once got zapped because of a timer I set on a 50V section (95% of the board was 12V or less) of a circuit and proceeded to forget the timer (for a transistor switcher) was set in my debug version. It was just 50v DC and tiny amperage but still very zappy.

In other words: please go home and I'll call you. 'Head on home' is a real expression. Similar ones are 'head over there', 'head to ...', all of which just mean 'go to'.
I mean more the "Why don't you ..." It's quite obvious that it's rethorical but it seems so nonsensical to put this into a question while camouflaging what is really going on.
It occurs to me that Spanish can also have this, which I only know because of this incident:

(I don't know whether it has exactly the same set of connotations in Spanish as in English, but it doesn't seem like the king expected Chavez to do something other than comply.)

#374I used to have a big CNC router. Like, one that you could mill a whole door on, if you wanted to.
One day I thought it would be a cool hack if I could rig up an Xbox controller to send movement commands. Long story short I managed to snap the bit by moving too much after a plunge cut. No safety glasses or anything; but a day or two later I did find some shrapnel from the bit embedded in a piece of foamboard I had near the machine, so that was cool...

Not quite robotics, but some of our servers kept powercycling , had to plug in the physical terminal. It was close to lunch, so I kept eating. The finale was a jar of mayo spilled into the guts of a 50k server. Best mayo I ever had.
What kind of server room allows you to bring food?

Don't feel bad :-) My 11 year-old son (a native English speaker) said the same thing to me just yesterday. "Hey, bud. Why don't you pick up those two plastic containers and follow me." "OK, but dad, it really confuses me when you say that. Can't you just say 'please pick up those containers'? It sounds like you're giving me an option but you're really not." Until he said that, I had never given it a thought. But he t…
Did your son really say "can't you just say?" :P
I think English littered with these suggestive polite negation statements.

Used to work in robotics. The QA folk were obviously very much sticklers for the full process of enabling the hardware interlocks before getting near the moving bits. One time a manager got mad at them for taking so long going through the full interlock process while repeating a failure mode. He therefore went up to the machine saying "look, it failed so it's stopped, that's how the code works!" At that point our bet…
I worked for a car company. We had robots for mounting parts. Big robotic arm several tons of pressure possible. I was part of the maintenance team, we get an alert for a robot malfunctionning. Coming in the area we see screwdrivers cleverly placed in all the safeties. And a guy trying to tweak the robot that was slowly moving...
Could you please elaborate? I don’t fully understand what’s going on with the tweaking?
Is he next to the malfunctioning robot?

I used to do robotics, I can tell you that the fact that it was the cheapest or the most hacky does not matter in the least. Everything can and will go wrong, even the priciest and well documented part. I used to have multiple clamps around the controller, message bus, the firmware and also a physical barrier, and yet would not feel safe with my fingers or person around moving parts.
Yep. When I have to work with robots, it's from a distance and with as much safety equipment as possible. I've seen too many physical, hardware, and software failures to risk anything I care about. Hearing protection is also important. A hundred pounds or more of metal slamming into itself at high speed makes a deafening sound.
I’ve read a story somewhere, that someone trying to fix something in the toilet had to be in a position close to the toilet, then the lid accidentally fallen shut and the guy had his hearing damaged because the toilet bowl somehow concentrated the noise in one point where his head was.
It’s weird how even ordinary things can be dangerously loud.

I think the malfunctioning was the guy shutting down safety meassures intentionally with screwdrivers?
In other words, some person did something very stupid, while thinking he is clever.

> The biggest problem with the saw stop is that wood when it is even slightly moist can set it off. Is there any proof of this? From my understanding, that's a myth. Demonstrated here at about 3:00 https://www.youtube.com/watch?v=NV6Jhw0hhBI
The one at our *kerspace has tripped numerous times on damp wood, laser-cut wood, shiny laminates that didn't register as metallic but apparently it was a full moon that day or something, etc. It's also saved a few legit fingers, so it's still a net win, but you've got to have pretty deep pockets to cover all the false trips.
I see, thanks!
