### Supress warnings when displaying numeric columns with NaN or very very big or small values 
```py
import warnings
with warnings.catch_warnings():
    warnings.simplefilter("ignore", RuntimeWarning)
    display(....)
```
### System wide display settigns 
```py
import pandas as pd
pd.set_option("display.max_rows", 5)
```

### Scoped display settings
```py
import pandas as pd
with pd.option_context("display.max_rows", 10):
    display(....)
```

**Typage Structurel** (ou *Structural Typing*) en Python.

Utiliser `isinstance(x, ABC)` revient à poser la question : **"Peu m'importe qui sont tes parents (héritage), est-ce que tu sais faire ce job (comportement) ?"**

C'est la pratique la plus robuste pour valider des entrées sans coupler votre code à des types précis comme `list` ou `dict`.

Voici les 3 "Contrats" les plus courants que vous devez maîtriser en Data Engineering, du plus laxiste au plus strict.

        print(lyr.name, count[0])

## 1\. Comprendre Jupytext (Le traducteur temps réel)

Le problème fondamental des Notebooks (`.ipynb`), c'est leur format.

  * **Ce que vous voyez :** Du code, du texte et des graphiques.
  * **Ce que l'ordinateur voit :** Un fichier **JSON** énorme et illisible.

Si vous ouvrez un `.ipynb` avec un éditeur de texte, vous verrez ceci :

```json
{
 "cells": [
  {
   "cell_type": "code",
   "execution_count": 1,
   "source": [
    "import numpy as np\n"
   ]
  }
 ...
}
```

C'est fragile. Une vir

### TAILSCALE
##### INTERFACE METRIC
By default TS interface is set to 5 which might be lower than your main ETH interface, causins some request to be sent to TS.
##### DNS / MAGIC DNS
In TS admin console, check how DNS is handled, by default magic DNS is enabled and can cause some issue (see above ), you can add other domain in the webbase admin console, or disable magicDNS interialy.

🔥 Issue with WSL2 for windows, as the tailscale Interface gets pickup for the netresolv.conf in l

RewriteEngine On
RewriteCond %{REQUEST_URI} !(^/aaa/bbb/)
RedirectMatch 301 ^/aaa/bbb/ https://aaa/bbb
RewriteRule ^(.*)$ https://www.aaa [R=301,L]

# WSL TIPS & TRICKS

## INSTALL
in cmd prompt / powershell as admin:
`wsl --install`
## GPU
-> [guide](https://joelognn.medium.com/installing-wsl2-pytorch-and-cuda-on-windows-11-65a739158d76)
## NETWORK
with tailscale installed my autogenerated config was erronous, no internet access ( DNS resolve issues)
Bit of a bitch at this stage ! doinga  fresh -reinstall

`sudo nano /etc/resolv.conf`\
add / correct the nameserver entry:\
`nameserver 8.8.8.8`

We would also want to stop automatic generation

## Différences entre `%` et `!`
C'est une distinction fondamentale qui sépare le bricoleur du développeur qui comprend son environnement d'exécution. Si vous confondez les deux, vous aurez des erreurs de chemin (path) ou d'installation de packages invisibles qui vous rendront fou.

Voici la différence technique brutale :

### 1\. Le `!` (Shell Escape) : Le Touriste

Le point d'exclamation dit au Notebook : **"Passe cette commande au système d'exploitation (Bash/Linux),
