Tried this “clean break” keyword this morning and worked great! No more duplicate interfaces and adapter code.
So much cleaner!

"Clean break." is a Power Word that directs the model not to goop things up with adapter code and backwards compatibility

The pipeline: give AI a memory system → give it unsupervised 5am sessions → find Chinese tags in its repo → confirm they’re accurate → wonder what else you haven’t noticed

best claude code trick: "ask me any questions before you get started" aka "it's okay to not know what i mean by 'fix it'"

Alex Pretti was an ICU nurse serving veterans. He died trying to protect protestors being assaulted. A group of anonymous & masked men fired chemicals into his face, beat him, disarmed him, and shot him in broad daylight in front of witnesses. Then his government smeared him & defended his murder.

I like the PDE name for what I’ve been working on recently.
It’s a Personal Development Environment. It’s built for how I code now with Claude. And gives me an excuse to hack on some agents which is really fun!

Trying out GLM-4.7 since my Claude plan ran out for the week after a busy weekend of coding
And It’s… ok lol
Think im just spoiled by Opus and that week of double usage limits didn’t help either 😆

Been working on a few projects in parallel this week, and that means it’s deploy weekend!
Got three things to deploy and posts to write about at least two of them. Hopefully to have something for you all to read by Monday morning 🤞

I used to dread Claude Code compacting. Context would get full and suddenly everything falls apart.
But now? Barely notice it. This stuff is improving crazy fast

Wow lol just discovered SQL has ROLLUP and I’ve been writing separate queries for totals forever!
just:
GROUP BY ROLLUP(column)
gives you a row with NULL that has the total count. COALESCE it to ‘Total’ in your select for readability and boom done!

I want to full send Tangled and move all my repos over
But the lack of private repos makes that hard…
98% of my repos are public but I don’t really want to setup CI and such on two different forges for that last 2% lol

TIL Elementor forms don't actually need WordPress to work. They just POST to whatever URL is in ElementorProFrontendConfig.ajaxurl
Change that one variable and they'll happily submit to any endpoint that speaks their response format!

Wanted to use tree sitter initially but gave up cause the lift was too big. Arborium is exactly what I wanted!

Big fan of @fasterthanli.me’s new library wrapping tree-sitter grammars up with a really nice Rust API. Spent a bit of the afternoon replacing a Syntect-based highlighting setup with an Arborium-based setup and much prefer it—and tree-sitter grammars are much more robust than old Textmate grammars!

Team… I think the CRDT route might have been a bad idea…
Or more accurately I think I don’t really need any storage over the actually saved backup files, which will already be backed up with iCloud

Gonna be honest... I got worried about deciding to go down the CRDT route earlier this week 😆
But just finished the bulk of the Operation Log and materializing the 'AppDB' from the Operation Log!
We aren't at full parity with the pre-CRDT version but its getting really close now

I didn't get an update out Yesterday and no video demo out this morning either
It turns out learning a new Platform in a new Language slows ya down a bit 😀
But making progress this morning, cleaning some things up and removing some hacks (like not refreshing the UI every 2 seconds in a timer lol)

Slow and steady progress here! It turns out having an 8 month old takes away from my free coding time 😅
The DB/CRDT work is almost done and then it’s cross device syncing (mostly just testing) and then onto a real design and fit and finish goodies I think!
