That doesn't make sense at all. Fail open means the method of it's use is still in use.

Say you have a door that has powered locks. You want it to fail "open" so that when the power goes out, it's still useable, and people can get out. That's the source of the term.


Assuming the guy is for real (the closest relation I have to EE is accidentally electrocuting myself at times), I'm pretty sure they're referring to circuits breaking open or remaining closed, hence the opposite meaning.

Took me a minute as well, cause indeed with a computer background, the meaning is completely the opposite. Just like in other security contexts (door locks).


The ambiguity is a good reason to avoid the expression entirely.

MIL-P-1629 from 1949 formally defines fail-open mechanical switches that release pressure on failure.

The concept goes back to a pressure cooker invented in 1679 by Papin.


contextual, as are air brakes 'failing closed'. However, I wonder how fast Papin made his spagbol with his pressure cooker

I spent a lot of time in SF in the early 2010s and I couldn't believe how absolutely terrible the internet was in the heart of silicon valley. It's incredibly sad honestly. You'd expect that SF would have the worlds top internet speeds, but nope. It was quite disappointing.


The UK is absolutely terrible. I've noticed this quite a bit in my travels there.


I am in Italy right now, in fact, spent a lot of time here. I can safely say, the 5G sim coverage is extremely spotty, and when you can get internet from a physical line, it's generally pretty poor speeds. I am pretty sure a lot of that 78% includes 1 bar of LTE coverage, so it's "technically" true.


Yeah, it's definitely super slow right now.


I use the app "flush" for this, and it works pretty well.


Does it source data from OSM? The app store page doesn't make clear what the data source is.


Go watch the dev videos, they feel 100% AI. The people are real, but everything else about it is uncanny valley.


Yep, I am a runner too, ran 6 marathons with this knot and run 20 miles a week. It just never comes undone.


I came across this site in the late 90's / early 2000's as well. I've been using the Ian Knot ever since, and even forgot how to tie my shoes "normally". I will teach it to anyone who will listen to me rant about knots.


I use both in my workflows. Though with all of the features of Resolve, I still use FCP for most of my content. FCP is just faster to edit and has a smoother end-to-end workflow. Resolve is still best for colorgrading and fine details, but if you just want to get a project released on time, nothing beats FCP.
