    > Well, the problem is not some "open source culture", but GitHub. Github's specific open source culture, if you like.

    Agreed.

    But GitHub is also slowly fixing this.

    For example the "Discussions" feature is enabled for specific repos. Here's it in action for the ImageMagick repo at https://github.com/ImageMagick/ImageMagick/discussions.

    It's only available on a small subset of repos tho. I was given the option to enable it in my one of my repos, but it's a fairly new project with no discussions yet https://github.com/nickjj/flask-db/discussions.

    I hope the Discussions feature becomes generally available soon.

  • axel

    Lightweight CLI download accelerator

    Latest mention: Give your Mac (imaginary) unlimited storage thanks to Disk Utility’s bug | news.ycombinator.com | 2020-12-26

    That said, "download accelerators" were also clever programs that would create multiple connections with the origin and use Range headers to download different parts of the file.

    Wonder why I don't hear of them anymore. Maybe because server upload bandwidth is more often generous enough to saturate your bandwidth these days?

    You can do this from the command line with axel: https://github.com/axel-download-accelerator/axel

    Latest mention: Rpi 4 meets Flutter and Rust | dev.to | 2020-11-06

    First thing to do is to set up the Raspberry Pi. In the README of the flutter-pi repo it's mentioned that flutter-pi should run without Xserver. Therefore I went with a headless version of RaspberryOS. Once you've flashed the os to a ssd card, follow the instructions in the flutter-pi README and install drivers for your touch screen of choice. Be sure to clone the engine-binaries branch of flutter-pi and place the files in the correct directories aswell.
