Regex Practical Guide

vindrin@outlook.com (Vindrin) — Sun, 15 Mar 2026 00:00:00 +0000

Regex Practical Guide

Regex clicks once you stop memorizing patterns and start thinking in pieces.

Core syntax

Pattern	Meaning
`.`	any character except newline
`*`	0 or more
`+`	1 or more
`?`	0 or 1 (optional)
`^`	start of string
`$`	end of string
`[abc]`	character class
`[^abc]`	negated class
`\d`	digit `[0-9]`
`\w`	word char `[a-zA-Z0-9_]`
`\s`	whitespace

Useful patterns

 
# Email (basic)
[\w.+-]+@[\w-]+\.[a-zA-Z]{2,}

# URL
https?://[\w./-]+

# IPv4
\b\d{1,3}(\.\d{1,3}){3}\b

# Date YYYY-MM-DD
\d{4}-\d{2}-\d{2}

# Hex color
#[0-9a-fA-F]{6}

Python example

 
import re

text = "Contact: hello@example.com or support@test.org"
emails = re.findall(r'[\w.+-]+@[\w-]+\.[a-zA-Z]{2,}', text)
print(emails) # ['hello@example.com', 'support@test.org']

Docker Basics

vindrin@outlook.com (Vindrin) — Wed, 25 Feb 2026 00:00:00 +0000

Docker Basics

Containers in practice — the commands that matter.

Core concepts

Image: blueprint (read-only)
Container: running instance of an image
Volume: persistent data storage
Compose: multi-container orchestration

Images

 
docker pull nginx:latest # pull from Docker Hub
docker images # list local images
docker rmi <image> # remove image
docker build -t myapp:1.0 . # build from Dockerfile

Containers

 
 
 
 
docker run -d -p 8080:80 nginx # run in background
docker run -it ubuntu bash # interactive shell
docker ps # running containers
docker ps -a # all containers
docker stop <id>
docker rm <id>
docker logs <id>
docker exec -it <id> bash # shell into running container

Volumes

 
docker volume create mydata
docker run -v mydata:/app/data myapp
docker run -v $(pwd):/workspace myapp # bind mount

Compose

 
 
 
 
# docker-compose.yml
services:
 web:
 image: nginx
 ports: ["8080:80"]
 db:
 image: postgres
 environment:
 POSTGRES_PASSWORD: secret

 
docker compose up -d
docker compose down

Linux Command Essentials

Linux Command Essentials

Survival guide for the command line.

 
pwd # current directory
ls -la # list with details + hidden files
cd /path/to/dir
cd ~ # home
cd - # previous directory

File operations

 
 
 
 
cp file1 file2 # copy
cp -r dir1 dir2 # copy directory
mv file1 file2 # move / rename
rm file # delete file
rm -rf dir # delete directory (careful!)
mkdir -p a/b/c # create nested directories

Text & search

 
cat file.txt # print file
less file.txt # paged view
grep "pattern" file # search in file
grep -r "pattern" . # recursive search
find . -name "*.py" # find files by name

Process management

 
ps aux # list processes
top / htop # interactive monitor
kill <pid> # terminate process
kill -9 <pid> # force kill

Permissions

 
chmod 755 file # rwxr-xr-x
chmod +x script.sh # make executable
chown user:group file # change owner

Networking

 
curl https://url # HTTP request
wget https://url # download file
ss -tlnp # open ports

Conda Environment Cheatsheet

Everything you need to manage conda envs day-to-day.

Create & activate

 
conda create -n myenv python=3.11
conda activate myenv
conda deactivate

Install packages

 
conda install numpy pandas matplotlib
conda install -c conda-forge some-package
pip install package-not-in-conda # fallback

Manage environments

 
conda env list # list all envs
conda info --envs # same, more detail
conda remove -n myenv --all # delete env
conda rename -n oldname newname # rename (conda 23.x+)

Export & reproduce

 
# Export (conda + pip)
conda env export > environment.yml

# Reproduce on another machine
conda env create -f environment.yml

Update

 
conda update conda # update conda itself
conda update --all # update all packages

Quick tip

Use conda-forge as default channel for better package coverage:
