I still marvel sometimes at the number of GitHub stars this repo has given that it has exactly zero users. (Fine I don't actually know for a fact it is zero but I think it's a pretty safe bet)

Working on new things for my upcoming beach sandbox game, Sandcastle 🌞 Say hello to the ducks! 🦆

someone told me recently that I'm too cynical and, honestly, it came off very self-serving and insincere

Someone just tried my voxel editing plugin 😮 and it kinda worked 😃 but not really 😬

Ok, Bluesky adding profile links is super cool. Oh and I see the little icon for my mastodon account. I think is a very pro-social move and I very much approve.

You can sign up for the monthly Zero to Accessible newsletter about accessibility on Apple platforms at buttondown.com/zerotoaccess... First issue coming soon! 😘

I think it's such a shame that, as far as I can tell, criticism of Swift's concurrency system has largely disappeared. I think there are still so many areas that could have been improved.

Our ultimate sandbox game, Sandcastle, is part of Steam NextFest! 🏖️ Unlock a variety of tools to gather wet sand, shape towering walls, carve moats, and craft mighty sandcastles along a tropical shore 🌞

I have put my other Swift evolution proposal concepts on hold. Language changes require enormous effort on my part and I'm afraid that I just don't think I can justify the time like I once could. It was great fun and hope to return to them one day!

SE-0540 is now finally merged! This was a fun one to work on and not as hard as I feared going in. Not quite sure if it will make it into Swift 6.5, and may be a while before it's practical to adopt anyways. But cleaning up all those settings in package files will be very satisfying.

I made an App to detect AI Slop Music. It runs locally on your device and uses Shazam and a custom trained ML model to detect AI generated music. Its completely free. I would appreciate it if you could spread the word. #indiedev #aislop #music #ml apps.apple.com/de/app/daft-...

Small new game alert! Over the past week with @padraig.org and @marc.bjango.com, we created The Last Tomato, a puzzle game about solving world hunger by growing a tomato. It’s got colorful radio waves, a robot, and runs in the browser. Please try it out :) padraigk.itch.io/tomato

Wavy Road is now available for pre-order! 🚗 I’ve been working on this game for a while, and I’m excited to finally share it with you. Pre-order here: apps.apple.com/app/id680494... A repost would mean a lot and help more people discover the game. Thanks for your support! ❤️

I've never seen anything like the @godotengine.org release blog posts before. They are like a celebration of the work and people involved.

Apple friends, I know your employer continually lets you down and disrespects your work. Reminder that ignoring bugs that don't impact your direct team is an easy and safe option. Your coworkers deserve some kind of (legal) resistance.

The rhetorical device I've obnoxiously latched onto lately: And what, *exactly*, does this tool do?

It's possible the people in control of Bluesky/Mastodon never find a way to work together. So, it's wonderful to see client developers step in.

It's a bizarre kind of whiplash though to think "dang Ukraine taking out Russian bot farms might actually have a meaningful impact on saving democracy worldwide" and "ah yes, the powerful in the Apple community are going back" in the same *hour*

Once Apple returned to X, and the company executed the (carefully planned, of course) laundering of bribery as just Cook, a return to X by other major personalities was inevitable. Still disappointing though.

The trailer is up! In just under two weeks, WOIM launches on Steam October 21st! www.youtube.com/watch?v=OS6h... #godot #gamedev #indiegame

Car camping friends: it is very expensive and logistically complex. But if you have been considering an induction cooktop for outdoor cooking, I highly recommend it. What a quality of life improvement.

I'm not an "accelerationist" by any means. But the ever-increasing negative consequences is quite a sight to behold. It's like watching in slow-motion.

This is a very good exploration of the complexity here

I'm not (even close to) in the field, but I have now read a few takes by the math community and they are giving me hope!

I really like the new iOS 27 text message suggestions. They give me a very clear idea of what the least-personal response would look like. Could still be a fine choice sometimes, but it's nice to have a reason to think twice.

Like many scientists, I’ve been mulling over the impact of LLMs on our fields. I’ve not yet seen it articulated, but I think there is a largely unspoken “invisible labor underclass” framework at play.

Still so rough. But here's an in-editor voxel tool adding and removing matter, then paint textures selected from a palette control. github.com/mattmassicotte/Vox... #Godot

I cannot decide which idea is more problematic: that we would have a need for "mind gyms" or that people would use them

A friend and I are creating a practical Git workshop: understand the commit graph, get out of tricky situations. We don’t know what exactly people want to learn, though; what they know already. Help us and fill this 2-min survey: tally.so/r/A7e7Xl We’ll publish the results. Reposts very welcome :)

Hmm starting to feel like this whole "non-Sendable" thing is catching on. I like it.

I was recently inspired to take another look at something that has caused lots of problems: marking just a method MainActor vs the whole type.

Me, in a patronizing tone: you are too afraid of running stuff on the main thread Also me: I should keep working on a years-long project to make it easier to avoid using MainActor in this one incredibly esoteric case

I haven't followed this Cornell stuff at all, but just looked it up quickly and I am now filled with rage and disgust which is saying something in 2026

Wrote up some thoughts on the role of LLM contributions in open-source projects.

I read it a long time ago, but I still think about The Innovator's Solution frequently. The realization that it is common to have a shallow and possibly plain incorrect understanding of why your product is successful is such an amazing insight.

📣 Today Apple is finally removing the dreaded Core Technology Fee!! To coincide, our new developer site is live with everything you need to know in order to ship your app to millions of AltStore users 🌎 developer.altstore.io

I had this idea of "cognitive forces". I dunno if it makes sense or not, but I was unable to let it go. Yes, it's about AI and yes, I'm rolling my eyes at myself too.

I know there's so much more nuance and complexity to it than this. But when a bad thing happens, and I see people say "see, dependencies are bad" I cannot help myself from interpreting it as "we should not work together on shared solutions" and I dunno it just makes me very sad especially lately

I really want to play the game on the fake Ikea TV

Recovery from the previous week Saturday: 20% Sunday: 30%

Found this jacket. Got it as a speaker gift for a Twitter conference. There were quite a few attempts to "acquire" my handle, including one that caused quite a bit of drama. I suppose someone will eventually get it now that it's abandoned. But the jacket (I never wear) is mine forever.

I have three things to do today and one of them involves C++. I better not leave that to the end, run out of time, and unfortunately have to push it off until next week.

new stuff 📈 collaboration 📉

It is just wild how much cognitive biases affect everyone else but not me I'm special

I get the objections to it, I really do. But I cannot tell you how many times I have explained why you cannot await a property assignment in Swift, and had to then go on to cover the alternatives and all their trade-offs. Not wonderful.

I think the Gates essay on AI is worth your time. I suspect/fear we will look back on this as wishful. But nonetheless, I am heartened to hear powerful voices like this, independent of how you feel about them personally, and I think it is a good sign.

If Apple thought 3rd party app support would have a material affect on Duo sales I have a suspicion it would not go like this
