Might as well cancel most programmers while we're at it. It's insane to lambast him for this when all he did was recommend some of Uncle Bob's videos on project management and programming.
One reply tweet notes "a complex system always operates in a failure state", but to find more discussion on this point it's worth noting that this is a restatement of: > "The Fundamental Failure-Mode Theorem (F.F.T.): complex systems usually operate in a failure mode." -- John Gall, General Systemantics (aka Systemantics , aka The Systems Bible ), 1977 https://en.wikipedia.org/wiki/Systemantics > Searching for "funda…
It's a really useful concept to keep in mind when designing or maintaining complex systems.

Was thinking the same. Once you exceed like 5 tweets in a thread, it becomes a small article and you would've been better off just writing an article in the first place. If you check the thread reader below you can see just how unstructured and incoherent it is compared with a simple article.
If you're genuinely curious: > I have ADHD: it makes writing blogs hard but Twitter easy. So it gets quickly tiring that every time I'm posted there [to HN] that the comments immediately go "why isn't this a blog? Twitter is a bad site for this kind of writing and I hate it blarg" https://twitter.com/foone/status/1440695857699962893 This exact comment of yours is a prime example of why foone hates it when their tweet…
There are two good lessons here: 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. 2) If a system failure can result in massive secondary damage, isolate that system. Warehouses receiving orbital payloads should probably be nice and far away from the base you care about.
> Warehouses receiving orbital payloads should probably be nice and far away from the base you care about. As mentioned elsewhere in the thread, shades of 'The Moon is a Harsh Mistress' by Heinlein. All your base are belong to dust.
This is why 4-20 mA is a common signaling standard in industrial automation. 4 mA means zero and 20 mA means one. 0 mA means broken transmitter !
Interesting. That makes sense, but what’s the reason for using current instead of voltage as the variable?

I have a bachelors degree in electrical engineering and work experience in hardware design and in the back of my mind I've always known this to be true, but this is the first time in my life I've ever heard anyone say this explicitly. EE pedagogy is badly broken in places.
As another EE, I had the opposite experience. Voltage drops due to wire resistance and transmission losses were drilled into our heads at any possible opportunity.
A bit of an off-topic: I only ever saw white traffic lights in the US and Canada (specifically, pedestrian traffic lights) and they confused me a lot at first - the rest of the world uses green. The icons displayed (hands) are confusing too: the rest of the world uses an icon of a man walking or standing.
The hand is to mimic that of a traffic cop. When they want you to stop, they hold up their hand to indicate that you need to stop. It used to be that you had to know english in order to understand them as well...many of the signs used to use the words "walk" and "don't walk"
Not familiar with this particular game. But in real-world systems design the default should be (?) boolean deliver = false; while( polling ){ deliver = readyToReceive(); if( deliver ) { send(); } }
Now you have the same problem.
Wow, Factorio is approaching Full Time Job levels of detail and work required to keep everything running. Incredible game that I will never play, I feel I’m back at my job!
Usually games or hobbies that feel like a job are much more fun because there's nothing wrong happening if you fail at it, or if one day you decide not to show up.

I may be biased because I am used to the hand but I find the walk and hand shapes are very distinctive compared to the walk and stand. However green on walk would be nice.
Very visually distinct, walking and standing, and green/red.
