Found a good command for compressing images in a PDF without messing with the text or anything else:

gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dDownsampleColorImages=true -dColorImageResolution=150 -dNOPAUSE -dBATCH -sOutputFile=output.pdf input.pdf

For everyone using "if grep" in #bash, you can use an equal-tilde operator to handle regex matching instead.

if [[ $x =~ regex ]]; then

Just don't put your regex in quotes and you'll be fine.

Have you ever seen a weird or interesting new shell recipe?

One of the best things to do before you try it yourself is to see if this site can tell you what it does and how it works.

Shell aliases make me a faster developer. In today's video I selected a bunch from my .zshrc file and walk through them:

https://youtu.be/O-a-UPgsHDk

Hope this is helpful and that you will use a few or roll your own.

Use aliases once, twice, thrice ... no big deal.

But use them 100s or 1000s of times and over time you save a lot of time!

If I were to do a 1:1 image of my #archlinux laptop setup to an SSD installed in a desktop, would I in theory run into any major issues?
Major changes:

• Intel to AMD CPU (done that before no issues)
• Intel iGPU to AMD dGPU (install mesa + fix VAAPI pointers?)
• more RAM?
• Change in audio hardware (both mobo onboard but laptop is unknown > Realtek; pipewire+PA backend)
• ?????
