Isolate Script

This script creates an isolated environment using Linux namespaces and cgroups, executes a provided Bash script, and then cleans up the environment. It ensures that any changes made within the isolated environment do not affect the host system.

How It Works

Argument Check: The script checks if a Bash script file is provided as an argument.
File Existence Check: It verifies if the provided file exists.
Cgroup Creation: A cgroup is created to limit the number of processes to 50.
Namespace Creation: The script creates new PID and UTS namespaces using unshare.

Extracting Emoji From Slack!

Slack doesn't provide an easy way to extract custom emoji from a team. (Especially teams with thousands of custom emoji) This Gist walks you through a relatively simple approach to get your emoji out.

If you're an admin of your own team, you can get the list of emoji directly using this API: https://api.slack.com/methods/emoji.list. Once you have it, skip to Step 3

HOWEVER! This gist is intended for people who don't have admin access, nor access tokens for using that list.

Follow along...

git clone https://github.com/lukechilds/zsh-nvm ~/.oh-my-zsh/custom/plugins/zsh-nvm
Add the zsh-nvm plugin to your .zshrc folder

Database Backup and comparation

Dump Postgres DB

pg_dump --data-only --inserts -h <DB_URL> -U <DB_USER> -f <FILE_NAME_TO_CREATE.sql> <DB_NAME>

Notes:

--data-only will dump only data to be inserted (not tables strcuture and relations)
--inserts will force to use INSERT statements and not COPY to avoid driver issues later on

⚠️ This gist was improved and transformed to a Blog post that is now hosted in Snyk blog.
