Using SSH

To use SSH between computers you need to have the right software setup on your server and the client.

These instructions are modified from this link.

Your server is likely to be a Linux machine.

In your Linux machine:

sudo apt install openssh-server
sudo systemctl enable ssh
sudo ufw allow ssh

Then you will need to retrieve your IP address for the machine. IPv6 can be used.

From the client:

ssh user@ip

Then enter the password when prompted. After connected, if you wish to disconnect:

exit
logout

To use the SSH Extension with VS code, you will want to modify the file at ~/.ssh/config so that it has this format:

Host memorable-name
  User user
  HostName IPv6-address

You should be able to connect to the server via a stand-alone terminal or VS Code now, although there is a known (apparently-harmless) bug in VS Code that asks for the password repeatedly although you have already been connected.

Notes regarding setup as inspired by The Primeagean

The Primeagean provided a couple of videos to show his developer setup on Linux.

Keybindings in editors vim

I learned neovim predominantly by watching his videos, which are not linked here.

windows manager: i3

https://i3wm.org/docs/userguide.html#:~:text=2.10.-,Exiting%20i3,you%20really%20want%20to%20quit.

• If using windows as the modifier key, relatively intuitive to bounce between apps (windows + arrow)

• Also easy to move them (windows + shift + arrow)

• Also easy to move between workspaces (windows + number)

• Also easy to move apps to other workspaces (windows + shift + number)

• key shortcuts to know

  • windows + enter (launch a terminal)
  • windows + shift + q (kill an application)
  • windows + shift + x (end i3 session) - then key based on prompt
  • windows + shift + e (end i3 session)
  • windows + d (search for an app to start)

Problems

• INCOMPLETELY FIXED

  • Failed to shut down from i3 successfully last time, requiring a hard shut down
    • Failed to modify the i3/config file so that the shutdown hot key works. However, figured out that Ubuntu will shutdown if you push the shutdown button on the computer, and that seems to work fine. The other hotkeys work well, including the lock screen function; type your password to unlock.
  • Mouse continuity between screens is not as intuitive (left to right, not top to bottom)

      • https://www.thinkwiki.org/wiki/Xorg_RandR_1.2
    • I have put this in my config, but WARNING, this will not work on other machines if the display names are not identical to those on my home setup
  • also keeps logging me out of/breaking Google Chrome sync (if do not exit gracefully first)
    • Exit all apps gracefully (windows + shift + q) before exiting i3
  • also, using open from tmux here seems to lock the terminal session until the opened file is closed (I don't think I saw this in the non-i3 windows manager)
    • https://superuser.com/questions/513496/how-can-i-run-a-command-from-the-terminal-without-blocking-it
    • when using open, append with & disown to keep the terminal active and dissociate the terminal from the running application
  • also does not use code to open text files when using open
    • Just have to be disciplined and use code <my file>
  • Upon starting up Linux kernel, getting error messages printed to the log:

    • Basically, these warnings are unavoidable on some motherboards when running Linux. But they are non-harmful.

Python with pyenv and poetry in Windows

These instructions modified from here.

Although one can install python system-wide, it is likely better to first have a virtual environment manager setup to manage your python versions. Thereafter, poetry is convenient for managing your python packages.

Start by installing pyenv:

git clone https://github.com/pyenv-win/pyenv-win.git $HOME/.pyenv

Add it to the path by updating your .bashrc file.

Then install your python version of choice, using pyenv install --list to find the version that is most recent and relevant for you. Then install and make the global version the same with:

pyenv install <version>
pyenv global <version>

Next, to download the install file for poetry, it is possible from powershell with:

Invoke-WebRequest -Uri "https://install.python-poetry.org" -UseBasicParsing -OutFile "$HOME/Downloads/install-poetry.py"

Then to install it, you go back to bash and run:

pyenv exec python $HOME/Downloads/install-poetry.py

Finally, you can confirm it worked by opening a fresh bash terminal and running:

poetry --version

After poetry has been installed, locate the pypoetry/config.toml file and update it according to your dot file.
