How I use my terminal

atuin is make-or-break, its a bigger deal than zoxide and being a coder without zoxide is like being an athlete with shoes for a different sport.

asciinema is a better way to do terminal videos.

Its weird that this is weird now: having your tools wired in used to be called "being a programmer". VSCode and Zed and Cursor and shit are useful additions to the toolbox, you gotta know that stuff by heart now too and you have to know which LLM to use for what, but these things are the new minimum, they aren't a replacement for anything. Even with Claude Code running hot at 4am when the PID controller is wide open, sometimes its going to trash your tree (and if it doesnt youve got it on too short a leash to be faster than gptel) and without magit? gl.

If you think you're faster than OP with stock Cursor? Get them to make a video of how to use an LLM with chops.

That's not to say that tooling doesn't matter at all. Just that, historically, it's been a relatively minor factor. Maybe LLMs have changed that, or are about to.

An athlete with shoes for a different sport might run 5% slower. In a winner-takes-all competitive environment, that's fatal; a sprinter that ran 5% slower than the gold medalist is just another loser. Most programmers, however, win by collaboration, and on a relatively smooth fitness landscape, not a winner-takes-all spike. Even in winner-takes-all regions like startups, failure always results from bigger errors. I think nobody has ever said, "My startup would have succeeded if we'd used Dvorak keyboards instead of QWERTY", or vim instead of VSCode, or vice versa. It's always things like feuding cofounders, loss of motivation, never finding product-market fit, etc.

It's like when people complain that leetcode is nothing like the job: yeah, it's a pretty bad test, but you're making a bad argument about that because CS knowledge is extremely relevant to the job, unless the job is assembly-line library composition.

I've consulted for companies that had all their dev boxes on coder or something, and you get really good at vscode really fast or you don't have much luck. It's more than 5%, but even stipulating that it's 5%, whoa, 5 percent?! By installing a bunch of stuff off a list on GitHub and dropping some aliases in your bashrc or zshrc? in a few weeks you're five percent more effective? Anyone in any field from banking to bioinformatics would think you were joking or a scam artist if you offered them 5% more efficient outcomes at that price.

Regarding OG editors like ed and ex and sam and stuff? I can absolutely believe that someone with a lifetime mastery of one of those tools could smoke a VSCode user, it's not at all obvious that VSCode is an upgrade to vim/etc. along any dimension other than low barrier to entry. ditto emacs which is about 1000x more powerful than vscode and the difference in library/extension ecosystem is not measured by size: the emacs one is identical to the vscode one with bottom 90% by quality sliced off the vscode one.

And this stuff compounds, you get a bit better at the tools and you can read more code faster, read the right code faster, start moving the derivative of the derivative.

It's also extremely non-obvious that collaboration at the kinds of scales and complexities that make exceptional skills or experience in it a top 3-5 core competency for people doing most software. Study after study going back to Fred Brooks and the Mythical Man Month have demonstrated that relatively small teams of people who get along very well coordinated by a relatively small number of highly technical managers who take the offload on the high-complexity cross-org collaboration is the golden ticket. It's the same reason computers have dedicated routing tables in the NIC and that those things talk to even bigger and more specialized machines that do all routing all day: you don't want to scale O(n^M) with the communication overhead.

A hacker needs to work really well with their immediate team, and have a good dialog with a manager who is both technical (to understand the work) and who devotes a lot of energy to complex collaboration.
