I've found (and locally fixed) an annoying performance bug on @X web! TLDR: go to a post with a lot of replies, and scroll up and down - notice it's laggy? There's a component that calculates the scroll parent, and then removes the scroll listener when unmounting. But it seems we don't even have a scroll listener most of the time, so we can avoid the heavy _getScrollParent function by wrapping it in a conditional This removes seconds of forced reflow and lag for me Would love to get it fixed! 🙏🏻 @X @engineering @elonmusk @nikitabier

PHP docker image built failed because the maintainer locked the comments and the CI has a step posting status to github comments.

Leaving this here, PHP 8.5.12 security patch is incomplete. ( needs further validation )
Readers added context they thought people might want to know
The PHP 8.5.12 release fixes the two specific CVEs (via state/bailout changes) detailed in official advisories; referenced "surviving paths" (e.g. var_destroy UAF) are separate pre-existing unserialize issues unrelated to this patch. php.net/archive/2026.p… github.com/php/php-src/se… github.com/php/php-src/se… github.com/dinosn/php-8.5…

This would be a pretty funny time for GitHub to have another outage.

if this PHP vulnerability allows remote code execution, doesn't that mean we can use the vulnerability to auto-patch all vulnerable servers?
