no one needs it, but it's cool:

an old version of the macOS flurry screensaver is open source, so a few prompts later we can have it ported to Metal and running in a tvOS app https://github.com/zadr/flurry

Claude Code has a freeform field for the default language, so you can, you know, enter whatever you want

```
❯ /config
⎿ Set defaultPermissionMode to default
Set response language to Shakespearean English

❯ how can the current app be optimized further?

⏺ A most excellent inquiry! Let me first study the codebase with great care, that I might offer counsel most wise and well-founded.

one regex and claude writes Swift like Perl

a long time ago I started writing a core data store backed by NSUserDefaults as a joke

fast forward to maybe a decade later, and vibecoding let me make a more useful version of that to finally get the idea out of my head - so here's a custom core data store backed by GRDB https://github.com/zadr/CDxGRDB

Looking into a perf problem for a holiday project, and its a whole mood

one of my legit fav things about candy corn are the random imperfect pieces. all yellow? 2/3 orange with a white tip? let’s go.

what other candy shows the tasty mistakes like that?

documenting for myself / the off chance it helps anyone:

after `port install libusb pkgconfig` I was getting `/Users/z/.usr/include/libusb-1.0/libusb.h:46:10: fatal error: 'sys/types.h' file not found` after a `make` to build `rpiboot` from https://github.com/raspberrypi/usbboot

which was fixed by manually setting CFLAGS= and an -isysroot to the macOS SDK within Xcode, e.g.

`CFLAGS="-isysroot /Applications/Xcode-16.2.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk" make install`

anyone have a version of `~/.rvm/scripts/rvm` thats, you know, not slow? currently hacking one up to assume macOS + zsh instead of re-checking on every env load but maybe someone else has beaten me to this already

Here's a lil Swift script that lists enableUpcomingFeature/enableExperimentalFeature values for your Swift toolchain (+ can let you know what is newly added)

Works by downloading headers and embedding and compiling C to read headers fetched from the internet (GitHub), so maybe don't trust it all the time
