smallest-iso

An aggressively minimized, bootable NixOS ISO, continuing where natkr's "NixOS but smol" left off. The post took a stock minimal ISO from 458 MiB → 183 MiB. This takes that 183 MiB result and pushes it much further while keeping it a real NixOS system that boots to an autologin root shell.

Merging JJ Workspaces into Main

This document describes how to merge multiple JJ workspaces into a single linear history on main.

When to Use This Workflow

Use this workflow when you have:

• Multiple JJ workspaces with independent development branches
• Work that needs to be consolidated into a single linear history
• Commits in different workspaces that you cannot directly rebase (causes stale workspace errors)

    lookup = stringToCharacters "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
    sliceN = size: list: n: sublist (n * size) size list;
    pows = [(64 * 64 * 64) (64 * 64) 64 1];
    intSextets = i: map (j: mod (i / j) 64) pows;

So you want to modify the text of a PDF by hand...

If you, like me, resent every dollar spent on commercial PDF tools, you might want to know how to change the text content of a PDF without having to pay for Adobe Acrobat or another PDF tool. I didn't see an obvious open-source tool that lets you dig into PDF internals, but I did discover a few useful facts about how PDFs are structured that I think may prove useful to others (or myself) in the future. They are recorded here. They are surely not universally applicable --
the PDF standard is truly Byzantine -- but they worked for my case.

Running into this error message when trying to run a mosh server on macOS Catalina? The steps below should solve the problem which is most likely either a $PATH and/or firewall issues.

command not found: mosh-server
Connection to X.X.X.X closed.
/usr/local/bin/mosh: Did not find mosh server startup message. (Have you installed mosh on your server?)

1. Install Mosh

## postinstall script to remove CCDA applications

# remove any existing version of the tool
echo "Moving the CC Cleaner app to Utilities in case users need it later"
rm -rf /Applications/Utilities/Adobe\ Creative\ Cloud\ Cleaner\ Tool.app ||:
mv /Applications/Adobe\ Creative\ Cloud\ Cleaner\ Tool.app /Applications/Utilities/Adobe\ Creative\ Cloud\ Cleaner\ Tool.app

# run the cleaner tool to remove EVERYTHING!
echo "Running the CC Cleaner app with 'removeAll=All' option"

Step 1

Download and run the Adobe Creative Cloud Cleaner Tool, their multi-app uninstaller and wipe assistant. Adobe does recommend running individual application uninstallers first, your call. Click the Clean All option.

Step 2

Type a one line command in terminal find ~/ -iname "*adobe*" and it's shows up all files which match pattern.

To remove all files

`sudo rm -rf /Applications/Adobe* /Applications/Utilities/Adobe* /Library/Application\ Support/Adobe /Library/Preferences/com.adobe.* /Library/PrivilegedHelperTools/com.adobe.* /private/var/db/receipts/com.adobe.* ~/Library/Application\ Support/Adobe* ~/Library/Application\ Support/com.apple.sharedfilelist/com.apple.LSSharedFileList.ApplicationRecentDocuments/com.adobe* ~/Library/Application\ Support/CrashReporter/Adobe* ~/Library/Caches/Adobe ~/Library/Caches/com.Adobe.* ~/Library/Caches/com.adobe.* ~/Library/Cookies/com.adobe.* ~/Library/Logs/Adobe* ~/Librar
