I always wished the throttle to be linked to slip sensor on wheels, say push back throttle a bit more when the wheels start slipping and not just wonders why WOT doesn't accelerate as fast as usual all while ECU is pulling power because of slip

We had users complain about migrating to MS Teams as the text part of it is almost entirely a piece of shit that every competitor does orders of magnitude better but management said "fuck it, we're migrating regardless", throwing oh-so-great arguments like "our customers also use it"

Only if you're extremely dishonest in comparisions.

Checklists at its core is just a list of common/required actions grouped in a list to don't forget during routine tasks. There is nothing limiting here, it is just a tool to aid repetitive/rare/complex tasks.

That's also easier way to design it in Factorio. When I was playing with Space exploration mod that's precisely what I did, the base sent "shopping list" and the provider sent stuff on that shopping list

> 1) Robust system design involves identifying the parts of your system that are mission-critical and always monitoring them. NASA missions have great automation and a 24/7-staffed mission control.

You should alert on critical parts but you should monitor anything and everything you can. It might be critical in finding out why system broke later on. Easier said than done for hardware but easy for software

The buggy behaviour of A caused buggy behaviour of B that caused buggy behaviour of C, just so happened to align enough to "look like it is working".

Double fuckup if the thing is backups and your data is gone. Reason why we check not only "does the backup job finished" but also "does the size looks right", because backup with 0 files still returns OK...

Eh, that heavily depends on language. Some have better tooling to get most of the typical errors out before the compile.

That being said I'm always suspicious and start to fiddle with them if I see test + code pass on first time

> For example, cars have "fail open" brakes but have independent cylinders so that it is relatively hard to have all four wheels fail at the same time (older cars had single master cylinders) - and one of the tradeoffs is that people want cars to get going immediately and not wait for brake cylinders to "charge up".

And emergency brake that's wholly separate circuit.

That's why in our monitoring we used nagios scheme + 1 (0 for invalid, 1 for ok, 2 for warning, 3 for crit, 4 for unknown)

> Largely because we have a long inversion of how government should act. It should have never needed "approval" in the first place, government should have to seek to ban a product, innovation, etc based on their own creditable evidence the thing is dangerous.

Uh, no. There should be a well defined standard of what light need (light area of this and that size or at least this or that brightness) and can't (low beams blinding oncoming traffic etc.) do, then let market work within those limits. The regulation should have actual research behind it. Pretty sure that's how it works in EU.

Then if for some reason behavior of lights on the market causes problem, the standard should be revised, not ban random products for breaking rules that haven't existed when they were created (aside from extreme cases I guess)

and they started issuing patents for dumb shit regardless of that

Yeah, another idiocy. They aren't reliable and need constant calibration, good luck driving a car full of drunks as designated driver...

Also interesting piece about why US was stuck in decades of same light design because of more stupid regulations

The reason doesn't really matter...

I remember Dota2 (video game) did this, people fake reporting had less reports and they counted for less, while people that were consistently reported players that got punished got more reporting power. Only one report per match "counted" too so a group of player couldn't gang on reports on one player.

Of course that could be abused as well,but you'd have to make a group of people that first got the good rating then reported same people and that would be significantly harder
