And the worst part is when it actually does and you have no fucking idea what went wrong before.
The pc had the hiccups and now it’s fine. Problem solved!
Some times my game engine needs a wake up run, then an actual run.
Yeah happens from time to time.
That’s step zero: rule out black magic
Those damn cosmic rays flipping my bits
Please tell me you look skyward, shake your fist and yell damn you!!!
I wonder if there’s an available OS that parity checks every operation, analogous to what’s planned for Quantum computers.
Unrelated, but the other day I read that the main computer for core calculation in Fukushima’s nuclear plant used to run a very old CPU with 4 cores. All calculations are done in each core, and the result must be exactly the same. If one of them was different, they knew there was a bit flip, and can discard that one calculation for that one core.
Interesting. I wonder why they didn’t just move it to somewhere with less radiation? And clearly, they have another more trustworthy machine doing the checking somehow. A self-correcting OS would have to parity check it’s parity checks somehow, which I’m sure is possible, but would be kind of novel.
In a really ugly environment, you might have to abandon semiconductors entirely, and go back to vacuum as the magical medium, since it’s radiation proof (false vacuum apocalypse aside). You could make a nuvistor integrated “chip” which could do the same stuff; the biggest challenge would be maintaining enough emissions from the tiny and quickly-cooling cathodes.
That feeling when it is, in fact, computer ghosts.
Me: “Hmm… No… No the code is good, it’s the compiler that’s wrong.”

It’ll be done soon, then I can go home. TGIF, am I right?
Yeah. And I can send a quick email to update the team after I get home from my 45 minute commute, then log off and go to the cottage in that cell signal dead spot by the lake.
Yeah, but sometimes it works.
It’s even worse then: that means it’s probably a race condition and do you really want to run the risk of having it randomly fail in Production or during an important presentation? Also race conditions generally are way harder to figure out and fix that the more “reliable” kind of bug.
Or it was an issue with code generation, or something in the environment changed.
Good luck figuring out why it sometimes doesn’t work 🙃
Mmm, race conditions, just like mama used to make.
There was that kind of bug in Linux and a person restarted it idk how much (iirc around 2k times) just to debug it.
This is 100% valid when dealing with code generation sometimes and I hate it
Legit happens without a race condition if you’ve improperly linked libraries that need to be built in a specific order. I’ve seen more than one solution that needed to be run multiple times, or built project by project, in order to work.
We call this sort of test “fuzzy”. If it’s really bad they call it by my own personal identifier of “unstable”.

The first is a surprise; the second is testing.
could be a race condition
Hmm…you may be right. I’ll get my Hispanic friend to run it and see if he gets the same result.
It works on my machine
ok, then we ship your machine.

i sometimes do that so i can inspect the error messages on a cleared terminal
Sometimes I forget what I was looking for and have to restart the mental loop when doing this.
Just had that happen to me today. Setup logging statements and reran the job, and it ran successfully.
I’ve had that happen, the logging statements stopped a race condition. After I removed them it came back…
Thank you for playing Wing Commander!
If that doesn’t work, sometimes your computer just needs a rest. Take the rest of the day off and try it again tomorrow.
One of my old programs produces a broken build unless you then compile it again.
I often do this, but I always hit Ctrl-S before running it again. Shamefully, this probably works about 10% of the time. Does that technically count as changing nothing?
That and a make clean can work wonders.
Autosave on focus loss dude.
The crazy thing is that sometimes this just works…
Well, duh! You need to use the right incantations!

Something something motive force.
I actually did this earlier today
I’ve only recently joined the dev world and I saw this post in the morning. Late this afternoon I’m doing a deployment that fails, couldn’t determine the cause as I’m a noob, before bothering a more senior dev for help I run it again… It worked.
it’s only dumb til it works
