Description of my development environment for Rust

My projects on Github are more like a tutorial than a finished product: bestia-dev tutorials.
Rust on Linux
This days I mostly program with Rust on Linux.
My primary desktop is Win10. Inside it I have WSL2, which is a Linux Virtual Machine. There I installed Debian 11 Bullseye.
I made a detailed description in https://github.com/bestia-dev/win10_wsl2_debian11.
For Rust development for Linux I have the container
rust_dev_vscode_cnt created from the image
rust_dev_vscode_img that I described here https://github.com/bestia-dev/docker_rust_development.
This container is ephemeral and can be destroyed any time. The important files inside it must be pushed to Github, else they will be destroyed with the container.
@startuml Github -> container: clone, pull container -> Github: push @enduml
Github is great, but...
They can cancel all my files in a second without warning. It happened to Iranian programmers when the USA imposed sanctions. It can happen to anybody anytime for any reason. Github is owned by Microsoft, the service is free and they don't have any obligation to the programmer whatsoever. If the service is free, you are not the customer with customer rights, you are the product with no rights whatsoever.
I want to be sure that Github is not the only place where my code is stored. I will prepare a folder on my computer to have backups of the Github projects. I will call the folder
Today I manually cloned all my Github projects. Later I can
git pull them and have it as a backup on my notebook disk. This folder is a backup, I will not develop inside this folder.
I prepared a utility that automates this process: https://github.com/bestia-dev/github_readme_copy
@startuml Github -> github_backup: clone, pull @enduml
I have a 2TB storage on Dropbox for 12€/month. It is not cheap, but I had bad experience with GoogleDrive and OneDrive in the early days. Maybe they are better now, but I don't want to retry everything. I am a paying customer, so I expect some responsibility from Dropbox. Maybe I am just delusional. They can go bankrupt in a matter of hours with modern financial games.
I am putting all my eggs in the basket of Dropbox, but eventually I make backups of all this files. I make backups on 2 external hard drives and I keep them in separate houses. Just for fun.
I use my app dropbox_backup_to_external_disk to make backups of Dropbox, because Dropbox does not have an app for that. Shame on them.
@startuml github_backup -> Dropbox: automatic sync Dropbox -> ext.hd_backup: backup @enduml
When I want to make an app for android I have to use Android Studio in Win10. All the files are pushed to Github. And from there they are automatically synced with github_backup. The complete diagram:
@startuml android_studio -> Github: push Github -> github_backup: pull github_backup -> Dropbox: automatic sync Dropbox -> ext.hd_backup: backup @enduml
These are usually small files and having them go up and down the internet 4 times is not a tragedy. Sure, I could save some time, copying them from one folder to the other locally. Then the sync will just index the files and not send them over the internet.
Rust on Windows
I don't want to install rust on my windows machine. Maybe use a cross compile inside the Linux container?
My websites are on a google Linux virtual machine.
On my local disk I always prepare the files and folders structure for the websites. Then I synchronize this folder with the directory on the VM.
It already happened that I deleted my VM on google and had to set a new one from scratch. I wanted a clean start. So having an identical copy on my local disk is paramount.
The local folder is synced with Dropbox.
confusion with names
Sadly, it is not possible to use consistently the same "name" everywhere, because there are always some limitation what characters are allowed. Alphanumerics are allowed everywhere, but dot, hyphen, underscore are not. Also uppercase and lowercase can be limited.
Variants of the name:
bestia.dev - domain name and primary, preferred name
info at bestia.dev - is forwarded to dev.bestia at gmail.com
bestiadev - docker
bestia-dev - gitub (bestiadev is NOT available 2022-03)
dev.bestia at gmail.com (bestia.dev is NOT available 2022-03, but it is not in use?)
LF or CRLF
Linux uses end-of-line (eol) LF, but windows uses CRLF. It can be super confusing, because some tools even make auto-correction and magically transforms them.
I want to have LF everywhere. It makes sense.
In VSCode I changed the setting
files.eol to LF. So, this is fixed for new files.
In windows I fixed
git to always use LF:
# globally git config --global core.eol lf git config --global core.autocrlf input
in every project separately I have to repair if there are CRLF somewhere:
git rm --cached -r . git reset --hard copy ..\dos2unix.exe . for /R %G in (*.txt) do dos2unix "%G" for /R %G in (*.md) do dos2unix "%G" for /R %G in (*.rs) do dos2unix "%G" for /R %G in (*.toml) do dos2unix "%G" for /R %G in (*.html) do dos2unix "%G" for /R %G in (*.css) do dos2unix "%G" for /R %G in (*.js) do dos2unix "%G" for /R %G in (*.svg) do dos2unix "%G" for /R %G in (*.json) do dos2unix "%G" for /R %G in (*.yml) do dos2unix "%G" for /R %G in (LICENSE) do dos2unix "%G" for /R %G in (.gitignore) do dos2unix "%G" del dos2unix.exe
Now I mostly use to dual-boot into Debian Linux. And there I use Podman to develope in Rust inside a container. Compiling is much faster than inside the WSL. Probably because of file acces. I suppose there are hundreds of small files and that is the major speed difference.
The standard Linux shutdown is very slow because of Podman. So I created a small bash script
#!/bin/sh echo 'podman pod stop --all' podman pod stop --all echo 'podman stop --all' podman stop --all echo 'shutdown -h now' /usr/sbin/shutdown -h now
But the command
shutdown needs root privileges. I used
sudo chmod +s /usr/sbin/shutdown to allow me as a normal user to shutdown.
Now I write
shut in the terminal to shutdown the computer faster.
open-source and free as a beer
My open-source projects are free as a beer (MIT license).
I just love programming.
But I need also to drink. If you find my projects and tutorials helpful, please buy me a beer by donating to my PayPal.
You know the price of a beer in your local bar ;-)
So I can drink a free beer for your health :-)
Na zdravje! Alla salute! Prost! Nazdravlje!
