# DEVeloper ENVironment (Ubuntu) 
This is a collection of personal tweaks/rituals that make Ubuntu feel just right for me like how a ballerina customizes their pointe shoes to feel just right for them, as well as some other useful resources I keep going back to.

It would be cool if this was an Ansible playbook, but I haven't made it there yet. 
This also has some handy commands that I always look up and then forget.

## GPU Drivers with Docker Passthrough - Make ML Go Brrr

## Hermetic and Reproducible Python Package Template

[Hermetic and Reproducible Python Package Template](https://github.com/garylvov/pixidock_template) authored by yours truly.

I love to use Pixi, which can be installed with the following.

```
curl -fsSL https://pixi.sh/install.sh | sh
```

## Vibe Coding

[My Agentic Vibe Coding w/ Claude Code Video Tutorial](https://www.youtube.com/watch?v=dVa7uNDu1ig)

[My Latest Written Guide to Vibe Coding and my Agents](/vibe_coding).

Claude code can be installed with the following.

```
curl -fsSL https://claude.ai/install.sh | bash
```

## The Classics
```
sudo apt-get install terminator # Make sure to turn on infinite scrollback: right click->preferences->profiles->scrolling
sudo apt-get install htop
sudo apt-get install nvtop
sudo apt-get install btop
``` 
### Code Editors

```
sudo snap install code --classic
sudo apt-get install vim
```

## Remoting in

### Classic
```
sudo apt-get install openssh-client
sudo apt-get install openssh-server
```

## Networking

The free plan from [Tailscale](https://tailscale.com/) works great (up to 100 personal devices!). 

I tried to use WireGuard alone once and quickly retreated to the comfort of Tailscale.

## SSH Security

### Slurm Stuff

[Slurm stuff](/slurm)

## IPMI / BMC

[Remotely turning on WRX90 Sage SE](/IPMI_BMC)

## Remote Desktop

I like to use [NoMachine](https://www.nomachine.com/).

~~Importantly, for NoMachine to work, in the Settings, under System, "Desktop Sharing" and "Remote Control" need to be enabled.~~ Edit: Turns out NoMachine does not depend on this, and this can lead to crashes on multi-gpu systems.

NoMachine can be installed headlessly with the following.

```
wget https://web9001.nomachine.com/download/9.3/Linux/nomachine_9.3.7_1_amd64.deb
sudo dpkg -i nomachine_9.3.7_1_amd64.deb
```

I want to try [Sunshine/Moonlight](https://github.com/moonlight-stream/moonlight-docs/wiki/Setup-Guide) but I haven't gotten around to it yet.

I need to remember to always do the following. Settings -> Sharing -> Remote Desktop -> On.

## Gnome Extensions 
Caffeine and Tactile are must have extensions IMO
```
sudo apt-get install gnome-shell-extension-manager
```

## Notifications to phone

[ntfy.sh](https://docs.ntfy.sh/)

```
curl -d "Backup successful 😀" ntfy.sh/mytopic

### Notes
[Obsidian](https://obsidian.md/)

[Obsidian Git Plugin](https://publish.obsidian.md/git-doc/Start+here)

[Obsidian Ubuntu 24.04 Permissions](https://askubuntu.com/questions/1512287/obsidian-appimage-the-suid-sandbox-helper-binary-was-found-but-is-not-configu)

Run Obsidian with the ``--disable-gpu`` flag to [prevent any glitches with Wayland](https://www.reddit.com/r/hyprland/comments/1aphbfq/comment/krv1np6/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button)!

Sometimes ``libfuse2`` is needed.
```
sudo apt update -y && sudo apt install -y libfuse2
```

## Space Preservation Part I 

Check disk usage with the following.
```
sudo apt-get install baobab
sudo baobab
```

If your ```overlay2``` folder gets huge, see the following.

## When Docker Gets Greedy (Space Preservation Part II)

Get rid of old docker images with the following.

```
docker system df
# Clear builder cache with the following.
docker builder prune -a -f
```


## Rebooting into recovery mode

```
sudo grub-reboot "gnulinux-advanced-$(findmnt -no UUID /)>gnulinux-$(uname -r)-recovery-$(findmnt -no UUID /)" && sudo reboot
```

## Kubernetes 
[Kubectl install](https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/)

[K9s](https://github.com/derailed/k9s):
```
wget https://github.com/derailed/k9s/releases/download/v0.32.7/k9s_linux_amd64.deb && apt install ./k9s_linux_amd64.deb && rm k9s_linux_amd64.deb
```

Handy commands that I always forget:
```
kubectl config get-contexts # Get all contexts
kubectl get namespaces # Get all namespaces
kubectl config use-context <CONTEXT> # Set Contexts
kubectl config set-context --current --namespace=<NAMESPACE> # Set the namespace for the current context
```

## Keybindings 

I've used Keyd in the past but tbh I didn't love it and am considering switching to Hawck. I think binding the capslock key to something that isn't useless is great.

[Hawck](https://github.com/snyball/hawck)

[Keyd](https://github.com/rvaiya/keyd)

Keyd conf file:

```
[ids]
*
[main]
capslock = layer(capslock)
[capslock]
e = oneshot(control)
q = oneshot(alt)
o = oneshot(shift)
p = oneshot(tab)
g = b
h = left
j = down
k = up
l = right
u = S-'
i = S-5
```

## Local LLM + Coding 


[Opencode](https://github.com/sst/opencode)

For local agentic coding:
```
vim ~/.local/share/opencode/opencode.json
ollama run SimonPu/Qwen3-Coder:30B-Instruct_Q4_K_XL
```


Running Ollama: 

EDIT: I no longer recommend using Ollama, the native [llama.cpp](https://github.com/ggml-org/llama.cpp) is great!

```
docker rm ollama 2>/dev/null || true && docker run -d --gpus=all -v ollama:/root/.ollama -p 11434:11434 --name ollama ollama/ollama
docker exec -it ollama bash
# Some favorites of mine:
ollama run deepseek-r1:70b
ollama run qwen:110b
ollama run qwen2.5-coder:32b

# Example of increasing context size:
echo \
"FROM deepseek-r1:70b
PARAMETER num_ctx 60000
PARAMETER num_predict 30000" > Modelfile
ollama create deepseek-r1-60k-context-and-30k:70b -f Modelfile
ollama run deepseek-r1-60k-context-and-30k:70b --verbose

# Afterwards, make sure to clean up with CTRL + C, CTRL + D, and then docker stop ollama
```

## Python Extract Method

Some VSCode Python extensions conflict with each other. I forgot how to resolve this. I think you may want just the Microsoft Python extension and as few others as possible. I also really like the rainbow indent extension it's great!
