Computing, Convivially — Sympolymathesy, by Chris Krycho
Digital technologies can be terribly destructive, but they can also be gloriously empowering. How do we tools for conviviality rather than means of domination?

Digital technologies can be obviously dreadfully destructive, but also really wondrous tools for good. Their sheer generality is both strength and weakness. How do we bend them toward humanism and away from the soul-deadening traps they often become? v5.chriskrycho.com/essays/comp...

@aeronautapp.com Loving the app. Feature request/suggestion: more keyboard shortcuts! In particular, it would be great to be able to navigate lists with something like ⌘⇧] and ⌘⇧[ or to switch between Home/Mentions/Activity/etc. with ⌘1, ⌘2, ⌘3, etc.
Keep up the great work!

Apropos of a product announcement I just saw go by: folks, using Tauri and web views does not make you more of a “Native App” compared to something using Electron. That is not what “native” means in the context of apps.

Quite surprised to hear that Native Instruments is insolvent. The private equity acquisition doesn’t seem to have gone well. The centralization (acquiring iZotope, etc.) was bad, too. I’d really love to see us get out of this cycle! But it’s obviously going to be a messy few years ahead /w LLMs etc.

A word to myself: keep resisting ICE while also staying open to mercy towards the human beings behind the masks. Their dehumanizing efforts do not justify my own dehumanization of them in return.

It is definitely annoying to have gone from turning in a <2:55:00 marathon as a *training* run at the end of September to running 60–90s/mile slower than I was then courtesy of a nasty herniated disc at L5–S1, but so it goes. (1/2)

Listening to the (mockup of the) whole of my in-progress #symphony as it stands today while doing day job work, and… yeah, it definitely needs the revisions I’ve mentioned I’m doing, but I *really* like it.
Which, I should, right? But it’s not a given.

Google Calendar pro tip (read: workaround 🤪): if you have a project calendar or similar—something that isn’t your own individual calendar—and you want to make sure you’re “busy” for events on it, you just (“just”) have to invite yourself to those events. 🥴

Once I finish this revision pass, it’ll be time to dig into Mvt. IV and see if I can get a draft of that across the line this year!
As usual, I also plan to try to write (and hopefully record and release) at least one other piece this year. Don’t yet know what, though!

Back at the steady work of revising the first three movements of my symphony. I did similar revision work on Mvt. I and II last year, but now that I have finished a draft of III and had some space, there’s a *little* that needs tweaking on I and a *lot* on II and III. #composing

Open-source maintainer responsibility: *Always* read the changelog (and preferably the detailed changes!) for the dependency bumps you are merging from Dependabot/Renovate/etc.
I just found one small “whoops, that’ll be no good for other users of this” that way; you might also spot much worse.

I have lately taken to trying not to use GPS past the first time I go somewhere new. Learn the route, and then be able to drive it independently in the future. Maps apps on our phones are super neat, but it is very easy to become needlessly dependent on them!

Well, Apple has gotten to the point where it’s sending notifications to try to get people to upgrade to Tahoe.
Not going to happen, not sorry about it. Maybe macOS 27 will be enough of an improvement to consider it, but right now I’m happy with «checks notes» a legible user interface.
