Rule 9 from Agans’s Debugging: If you didn’t fix it, it ain’t fixed
Intermittent problems are the worst…
The problem is, how do you fix it if you can’t make it break?
The worst thing is when somebody comes to you saying “yeah, I had this problem yesterday, but it’s working now”.
this is a case for excessive logging man
likely won’t help you actually fix the issue because miraculously you didn’t log the three variables you actually need but it’ll make you feel better in the meantime
and gives you some headroom in improving performance since it’s being choked by the excessive logging

Why does everything have to be about race?!
Because you gotta go fast.
Wonderful comment, solid laugh out of me.
The longer I’m in IT, the more I realize that the adeptus mechanicus might be on to something with beseeching the machine spirit.
A lot of people think I’m joking when I say I’m a good at what I do because I’m a witch doctor with computers. Software Engineering requires experience with the occult, at a minimum.
“In my professional opinion, this network is haunted.”
…haunted?
(Points to various certifications) “HAUNTED.”And for some reason printers seem to be the place where the spirits are strongest
I think you mean demons
The demons are attracted to doorways, passages between spaces, worlds, and realms. And printers are the ultimate doorway: a portal through which ideas and concepts can leave the software realm and enter the physical
In effect, we conjure the spirits of the computer with our spells.
I actually had a concept for a fantasy world, where magicians craft spells much the same way software devs do. So you make your spell and publish it to the ether, and then anyone can invoke it using the magic word (package name), assuming the have the right dependencies available (eye of newt or whatever). But spells might have bugs. So if you used eye of red newt while the spell smith built it with the expectation you had eye of blue newt you might get unintended consequences
i mean it’s pretty common for runes to just be conceptual programming languages and if you do something wrong then instead of having a lighter you get a bomb
The other day I launched an old game and got met with an error, something about directX9 and missing a redistributable file or something. Decided not to fuck with it.
Yesterday I launched it again to take a closer look at the error message to see if I could fix it. No error message, game booted without issues.
My confusion.
Did you reboot your PC after installing? Games often included DirectX redistributables which required a reboot to fully install.
Don’t forget them cosmic rays flipping bits in your memory.
It got scared and decided to fix itself.
if (new Date().getDay() % 2) { runCode(); }I have this issue once in a while with PowerShell.
The environment gets f’up as you develop. You get strange shit happening or it blows up.
Restart PowerShell or reboot and it’s all good
I also want to know
Still better than my Go experience 2 years ago.
- fails when deployed, after adding debug statements looks like in one structure there’s 2 instead of 1, and looking at the code that should be impossible. Issue happens every single time.
- the same exact unmodified container when downloaded and run locally works correctly every time.
lucky, you have code gnomes. leave out an offering of mountain dew and pizza rolls to appease the spirits.
Build caches are a bitch.
I had that happen with embedded programming when you forget to flush the eeprom after changing your saved values.
hmm embedded. Beautifuly memories from uni. One lab my team forgot to remove a register whose supposed purpose was only enabling a communications bus (documentation didn’t mention it doing anything else). Turns out that same register disables the dac which we needed for the new excersise. You learn to love the hardware datasheets real quick.
And when the data sheet is wrong that gets fun. You start parsing I2S for each bit and record the result until you see a pattern. Or when your program crashes the USB and you can’t reupload without hitting boot or reset but they are inside the box.
MY PEOPLE!!! My code recently decided to not erase the flash when writing new firmware, bricking the device. Good times. (Old code || new code does not make for a working system)
I’m dealing with this right now. Making the largest embedded project for me (self taught) RP2040 in Cpp with a TFT touch screen, an IMU with fusion, a strip of “neopixels”, a 12v battery voltage reader, some Lemo connectors and custom cables, all in a 3D printed case in 3 parts. I’m so close to the end but still facing some code issues.
This is the project I’m working on: CyberLevel. A gyro digital level for Steadicam. video
Pixels are wonderful, but such a perilous path…
Start playing with a pixel, then get a board with WLED set up, then start running xlights on a beaglebone to synchronize several instances, for holiday lighting. Suddenly there’s several hundred leds in the front yard
Haha! I feel you. Luckily my project only involves about 20 pixels on a high density strip (332pixels/m) to be used as a small 1D display.
I know some of these words
On small computers like Arduino there is a very small memory called eeprom that stays when powered off. It saves ultra low level data (at the bit and byte level) if you don’t “format” after changing what is being saved where it then tries to read gibberish and things go bonk.
Cosmic radiation could always wreak havock by simply switching a 0 to a 1. It appears The Universe is Hostile to Computers.
In university, we had to complete weekly tasks. A few times, the validation script provided by my professor returned an error, meaning that my solution had a mistake. When I tried rerunning the script the following day, my answer was accepted. At the end of the last lecture, my professor came to me and told me that I was usually the first one to hand in a solution and that he sometimes used my answers to validate his results.
So… Network issue. I’m not falling for those ever again.
As a network engineer, I hate you. Everyone blames network, even when the program/code/script/etc is the only thing that won’t work on it.

Maybe it only works on even dates, which is, you know, perfectly normal.
I’ve recently had the opposite: code worked then the next day without anything changing it didn’t.
Turned out the J-Link programmer always needs the license check to work, but that expires every day at midnight. It only prompts again if you choose the app and restart it. So I couldn’t get my debugger to work and spent hours trying to figure it out until I did the best thing. I turned it off and on again.
