PATH tips

wizardzines.com/comics/path-ti…
panel 1: add a directory to your PATH at the end: export PATH=$PATH:/my/dir at the beginning: export PATH=/my/dir/:$PATH in fish: set -e PATH $PATH /my/dir panel 2: you shell's config file bash: .bashrc or .bash_profile (exactly which one is a bit of a rabbit hole sadly) zsh: ~/.zshrc fish: ~/.config/fish/config.fish panel 3: show what your shell is actually going to do when you run the program type python3 instead of running what's in PATH, sometimes it'll run a builtin or alias or cached entry panel 4: show the first match on your PATH for a program which python3 panel 5: show ALL matches on your PATH for a program, in order which -a python3 panel 6: look at your PATH echo $PATH panel 7: show each entry on its own line echo $PATH | tr ':' '\n' panel 8: clear the PATH cache (bash/zsh) hash -r why you might need to do this: bash and zsh cache PATH lookups, so sometimes updating your PATH doesn't work properly

For a while, I've been working on a startup to design the next generation of day & night trains, optimizing space usage, comfort & economics all at once. The idea is to make night trains economically viable, a true alternative to flying, while being super comfortable.

website-making class where you have to recapitulate the history of the web -- week 1 you can only use the very first HTML tags from HTML 1.0 or whatever, then over time you get to use <img>, then CSS, JavaScript 1.0, XMLHttpRequest, etc

Corollary to this: you can have an outsized impact on the world by being one of the few people who DO publish fresh information online on your own web pages

A decade ago I felt like I could find anything on the Web. Now I feel like I can barely find anything. People just don't put information on web pages anymore.

git add -p

(this is bonus comic #4 for "How Git Works" wizardzines.com/zines/git, covering some topics that I didn't have space for in the zine)

permalink: wizardzines.com/comics/git-add…
panel 1: git add -p lets you stage some changes and not others (this is one of the tasks GUIs and IDEs are best at, but I always use git add -p anyway) panel 2: what the interface looks like filename, diff, your choice ("Stage this hunk [y,n,q,a,d,s,e,?]") panel 3: y(es)/n(o)/q(uit) y means "stage this change" n means "don't" q quits, keeping what you did so far. pretty straightforward. panel 4: how to check your work git diff --cached will show your staged changes panel 5: s: split into 2 parts s will split a diff into smaller diffs you can say y or n to individually, like this: panel 6: how to split a diff if there's no newline You can use the e ("edit") option to edit the diff manually: * to remove a - line, replace "-" with a space * to remove a + line, delete the whole line (or you can just say 'n' and edit your code! that's what I do!)

git worktree

(this is bonus comic #3 for "How Git Works" wizardzines.com/zines/git, covering some topics that I didn't talk about in the zine)

permalink: wizardzines.com/comics/git-wor…
panel 1: git worktree lets you have 2 branches checked out at the same time person: "ugh, I want to take a look at this other branch, but I have all these uncommitted changes..." git worktree: "i can help!" panel 2: creating a worktree git worktree add ~/my/repo mybranch Then you can run any normal git commands in the new directory: $ cd ~/my/repo $ git pull panel 3: two worktrees can't have the same branch checked out Here's what happens if you try: $ git checkout main fatal: 'main' is already checked out at /home/bork/work/homepage panel 4: it's way faster (and uses less space!) than cloning the repository again Because worktrees share a .git directory, it just needs to check out the files from the branch you want to use! panel 5: other worktree commands List all worktrees: $ git worktree list Delete a worktree: $ git worktree remove ~/my/repo panel 6: sometimes I use worktrees to keep my .git directory and its checkout separate

@b0rk this is such a great resource. I’ve been using git for years and immediately learned multiple useful commands and git architecture concepts from the first few pages. thank you for this work!

git submodules

(this is bonus comic #2 for "How Git Works" wizardzines.com/zines/git, covering some topics I didn't talk about in the zine!)

permalink: wizardzines.com/comics/submodu…
panel 1: julia: "I find submodules confusing and I avoid them if possible, but here's what I've learned from other people's writing* on submodules!" * especially Dmitry Mazin's great "Demystifying Git Submodules post panel 2: submodules let you store another git repository as a subdirectory git submodule add https://github.com/jvns/myrepo ./myrepo Git will store the commit ID and URL of the submodule panel 3: gotcha: cloning a repository doesn't download its submodules To get the submodules, you can run this after cloning the repository: git submodule update --init panel 4: gotcha: git pull and git checkout don't update submodules gotcha: git pull and git checkout don't update submodules To actually update them, you have to run: git submodule update every single time you switch branches or pull panel 5: gotcha: git submodule update puts the submodule in detached HEAD state

interactive rebase

(this is #bonuscomic #1 for How Git Works wizardzines.com/zines/git, covering some topics that didn't make it into the zine!)

permalink: wizardzines.com/comics/interac…
panel 1: git rebase -i lets you garden your commits I use it like this: 1. make commits chaotically, git commit -am 'wip' 2. clean up with git rebase -i before sending them off for code review panel 2: interactive rebase's UI is a text file when you run git rebase -i main, it'll open a text editor with something like this in it: pick 399990 add some padding pick fb59d8 french translation pick 617b19 sort titles pick 31b81f hashchange panel 3: deleting commits You can delete a commit just by deleting that line in the text editor! (the line "french translation" is crossed out) panel 4: combine commits with fixup Here's how to combine all 4 commits into 1 commit: (f stands for fixup) pick 399990 add some padding f fb59d8 french translation f 617b19 sort titles f 31b81f hashchange panel 5: check that the tests pass with exec You can run make test on every intermediate commit to make sure your tests pass like this: git rebase -i --exec "make test" main
