I recently made a post discussing my move to Linux on Fedora, and it’s been going great. But today I think I have now become truly part of this community. I ran a command that borked my bootloader and had to do a fresh install. Learned my lesson with modifying the bootloader without first doing thorough investigation lol....
Totally valid! Theoretically with more experience it may be easier / faster to fix but…idk
See this is why I keep /home on a separate partition (or drive in some cases). I can reinstall or switch distros anytime without worrying about all my files (they’re backed up, anyway but doing a restore is a pita).
I’m an EE by trade focusing on embedded devices, but most of my work is in relatively low-power STM32 applications. When I stopped following developments in hobby kits, it was mostly Arduino Unos slowly driving I2C OLED displays....
PS: to me RPi is overkill for all but the most intense compute requirements. So is the esp32 to a lesser degree. Don’t always need 240MHz dual core RISC with FreeRTOS and 2.4G radio…
I default to Arduino, usually attiny devices for simple, low power stuff. I am really liking the new TinyAVR line. Quicker programming, way more functionality, etc.
For whatever reason I usually get pain in my fingers not wrist. And usually only when gaming for a long time. Pretty sure I move my whole arm when using a mouse. Maybe that’s why?
It is nowhere near necessary to reinstall the OS to fix anything… at least for Mint and Raspbian which are the two I’ve used over the last decade. I may have done an upgrade on mint a few times. Otherwise it chugged on merrily.
PS: now that I think about it I’ve never reinstalled windows on my old laptop either. I like to find the root cause of problems and fix them rather than giving up and reinstalling… call me crazy?
Recently I stumbled over an article, about how to customize your shell prompt. What really surprised me, is that it lacked one of the most basic tips I learned nearly 20 years back: Always display a timestamp in the prompt, to be able to check how long a process is running or when it ended. (Don’t need it daily, but every so...
Sure, yes, but my point was that we don’t have evidence specifically for the existence of dark matter.
We have evidence that is not explained by visible, detectable mass.
Dark matter is the current favored theory which happens to explain discrepancies between what is observed and what is expected.
But I don’t think we can logically conclude dark matter is the only explanation, which is what your original statement seems to imply. It is the best explanation that we have so far.
If we place objects on the dining table the night before and observed them lying on the floor the next morning, we can’t claim “we have evidence for sleepwalking residents.” There may be another theory that explains it, such as: the cat is knocking the things off the table. We need additional evidence to determine which theory fits or else come up with a new theory.
“In astronomy, dark matter is a hypothetical form of matter that appears to not interact with light or the electromagnetic field. Dark matter is implied by gravitational effects which cannot be explained by general relativity unless more matter is present than can be seen,…”
Unless you’re aware of some case where dark matter has interacted with light or EM fields?
So we see these gravitational effects that either means general relativity falls apart under conditions we have yet to identify or there is more mass than we can detect with the EM spectrum.
I’m not arguing against the existence of dark matter. You’re misunderstanding my intent.
I’m not even arguing. I’m just pointing out that your original statement isn’t quite correct.
But Dark Matter is a great scientific theory. It probably will hold up. I can’t wait to see what we learn next!
Anyway I probably shouldn’t have even responded because it doesn’t matter in the big scheme of things and my thumbs are tired from arguing against bigoted assholes in other places (I’m on a phone) so… peace

Came up with this late at night. Not while being anywhere near a laptop though.

I sort of left the hobbyist electronics world back in 2018, and now everything seems to have an embedded Raspberry Pi in it. What's the best way to catch up?
