Atuin replaces your existing shell history with a SQLite database
Or use the excellent bash-preexec plugin that atuin itself relies on to achieve this in a cleaner way: https://github.com/rcaloras/bash-preexec

Opppppsss you did it again
Funny you say that when the sketchiest part of this submission is the shell script it uses to intercept every command you run: https://github.com/rcaloras/bash-preexec/blob/master/bash-pr...
I don’t know rust, but the rust files in this repo look very straightforward. (Why wouldn’t it? It’s just matching a few hardcoded commands. It’d be easy in any language)

How Warp Works
Thankfully, most shells provide hooks for before the prompt is rendered (zsh calls this precmd) and before a command is executed (preexec). Zsh and Fish have built in support for these hooks. Though bash does not have built in support for these hooks, scripts like bash-preexec exist to mimic the behavior of other shells. Using these hooks, we send a custom DCS (Device Control String) from the running session to Warp. This DCS contains an encoded JSON string that includes metadata about the session that we want to render. Within Warp we can parse the DCS, deserialize the JSON, and create a new block within our data model.

What am I running inside my bash? (2014)
It's attached to the preexec hook of https://github.com/rcaloras/bash-preexec, so is run before every command. This means that everything goes into one easily-greppable file, but is still separable by PID/host machine - since my work has me walking around a large facility, often I'll remember where I was when I did something but not exactly when, so can narrow down by machine.

Warp VS Wave Terminal - a user suggested alternative

Linux version of Warp terminal is here
I'm trying out Warp for the first time, and an immediate accessibility issue for me is that the text is simply too small to read for a lot of the UI elements (context menu, side bar, tab bar…). The size should be configurable for all of the elements, not just the terminal view. I think I would also be fine with a setting that just scales the whole UI.
I did notice there is an issue for it already: https://github.com/warpdotdev/Warp/issues/1443

How To Change Your Zoom Background With Code
Warp is a Rust-based terminal with AI built in. I like it because it has things like autocompletions, history search, click-to-edit, and theming out-of-the-box. Feels super modern. And if you do want to try it out, use my referral link & get a free theme!)

OpenAI Whisper: Transcribe in the Terminal for free
Unless you want to type this every day, I’d recommend creating an alias. In my case, I’m using Warp, so I’ll right-click the command and choose Save as Workflow to save my script as a workflow. Warp AI will even help me autofill the title and description and detect variables.

Keystroke timing obfuscation added to SSH(1)
This makes me wonder about newer terminal emulators on maccOS like Warp[1], and if they're for example taking all input locally, and then sending it over the remote host in a single blob or not? I imagine doing so would possibly break any sort of raw-mode input being done on remote host but I'd also imagine that is a detectable situation in which you could switch into a raw keystroke feed as well.
