From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Can anybody comment on their experience using Arduino and ESP with Linux? Especially does Linux handle COM ports better than Windows? There's a seemingly immortal problem of COM ports becoming unusable until you go into Device Manager and uninstall them (again and again) - and if that doesn't work, reboot Windows. I experience this less often now than say 5 or 6 years ago, and sometimes it's my fault, but jeez.
Yes, com ports work way better than in windows. I've done a lot of embedded development on linux and it's way more pleasant than in windows. One thing you do have to keep in mind is that access to com ports (USB and real) requires root access by default, but once you've set the udev rule up, it becomes accesible to normal users and/or group of users. After that, it works flawlessly. Android dev also works great and imo better than on win. Proprietary jtags may be an issue, but I've never actually had an unsolvable situation.
Thank you, that's massively helpful! Pasting your comment into my ESP32 project notes so when I soon move to Linux I can remember to figure out the udev rule and jtags.
Running this command was literally the only thing required for me to get access to the com ports. After that, everything worked perfectly.
sudo usermod -a -G dialout $USER(note that $USER is part of the command - do not replace that with your actual username)
Same, programmed an arduino last week, that was all I had to do too
I've had wemos d1 boards from AliExpress show up as a brltty and the braille teletype driver grabs the device. Just something to look out for on some distros
