wget and curl both fetch data over the network, but they have different design goals. The simplest way to remember it:

wget = download files curl = talk to services

Below is the clean mental model, then details.

certutil -hashfile "Path\To\Some\File.mp4" SHA256

If you're curious about file hashes, they’re like digital fingerprints. If two files have the same hash, they’re bit-for-bit identical. Even one byte of difference would change the hash.

🔧 To check the hash on Windows (no install needed):

✅ For SHA-256 (recommended):

Open Command Prompt and run:

The -u in git push -u origin main is a shorthand option for --set-upstream.

When you use git push -u origin main for the first time for a local branch, it does two things:

Pushes your local main branch to the remote repository named origin. If a main branch doesn't exist on the remote yet, Git will create it.
Sets up a tracking connection (upstream) between your local main branch and the remote origin/main branch. This means that Git now remembers that your local main branch is associated with the main branch on the origin remote.

Why is this tracking connection useful?

Once the upstream is set, you can use simpler Git commands in the future:

# Version 1: Full WxH specification
ffmpeg -i input.mp4 -vf scale=640:360 output_640x360.mp4

# Version 2: Width only, adjust height automatically
ffmpeg -i input.mp4 -vf scale=640:-1 output_640xauto.mp4

# Version 3: Height only, adjust width automatically
ffmpeg -i input.mp4 -vf scale=-1:360 output_auto_x360.mp4
