heads up if you're about to migrate Paddle Classic subscriptions to Paddle Billing using their migration tool:
if you have existing custom_data fields in Classic subs, the structure will be different in Billing webhooks, and this isn't documented 😬
migration tool is pretty good though

if you're building a big app using AI without a design system guide, your app turns into a Frankenstein of inconsistency ☠️
you ask it to build a new page, it builds a page based on the last page it built, without context of your full design
so, create a design system in your agents[.]md

I'm not into agent orchestration that much, mostly because the tech isn't just quite there yet, but I can definitely get behind the name of this orchestrator 😊

I've been developing software for decades, and I still get extremely giddy when I find a new method of doing something, usually making it 10x faster and cleaner

yay, MuteDeck is getting a Safari extension at last!
Apple's submission process for extensions is grueling, made so much more complicated because you need to submit an app with the extension embedded instead of just an extension
review process took 3 weeks
this is why Safari has almost none 🤔

this is gold. I asked Claude to add protection against empty customer names
it did that, but also defaulted to 'there' as the customer name, which had me puzzled at first
but Claude knew the SendOrderFollowUp email was using this: "Hi {$firstName},"
so an empty name would be "Hi there,"
🤯

TIL from Claude: the SQLite UNION statement
got two tables with similar data and want to query both in one query?
below is an example that'll query two tables, get the same data, and use 'app' and 'web' as differentiator from where the data came from 👇

just helped a customer that was hit by a livewire RCE
actors are actively scanning and exploiting the <3.6.4 issue in CVE-2025-54068
make sure you update packages regularly, but definitely when there's a RCE!

I think I figured out how to make backups of the enormous amount of time spent in Cloudflare's console setting things up
using terraform to dump all config to .tf's via github, having it commit the output to a repo, detect changes and create a release out of it - so I get an email with a diff 😊
