Responded to @kasparsd:
Why Users Reach the Price but Don’t Buy
I analyzed multiple rrweb session recordings (36k+ events across several user sessions). These are clear, recurring behavioral patterns that explain why purchases stall near the end — even when traffic quality and checkout functionality are fine.
This is not a traffic problem.
This is late-funnel decision friction.
Can AI help optimize your landing pages and help drive sales from actual user session data?
We enabled user session recording using PostHog (which uses rrweb behind the scenes), and drove Meta ads to the page.
Then used AI to extract those 36k+ events into a single file (right from the browser console) and asked it to analyze the results.
Here is what it said:
Turns out that building a "Clear formatting" feature for the WordPress block editor is more difficult than I imagined.
Many blocks have the inner content as part of the `content` attribute but things get difficult with RichText, for example.
Do you have a solution for this?
Really great insight into image AI and how everything is just vector math at the end. https://chaos.social/@blinry/115816148248650239
New on blog: Notes on Umami Analytics https://kaspars.net/blog/umami-analytics
Trying to find an alternative to Screen Time for kids on macOS since it’s completely unreliable and the UX is terrible.
AdGuard/PiHole with a macos user profile that enforces DNS seems like one option. Need to be local and selfhosted.
Suggestions?
Add logging to my kitchen-sink WordPress plugin with handlers for error_log() and Query Monitor.
Nice to have info/debug level data while developing and warnings+ on PROD.
How are you handling this in your plugins?
After sunsetting a VPS that was used for backup of other VPSes, I decided to have #restic send everything to a restic-rest instance (as docker container) on my #homelab NAS over #wireguard.
Amazing how restic can backup to so many destinations (s3, sftp, http) over so many transports.
Did you know that HTTP3 is already supported by 92% of browsers and can offer 10-20% performance improvements (mostly to LCP) especially for mobile users?
Nginx added support for HTTP/3 two years ago in version 1.25.0 so it is available in most recent Linux distributions.
Just make sure to allow UDP connections on port 443 in your server firewall to avoid hours of debugging like I did 😂
Did you know there is a way to check the historic web vitals for your sites from actual user data?

Has anyone had luck registering for AliExpress API access?
Getting auto-rejected and not sure what to try next.

The #FAIR plugin for WP doesn’t like iOS Safari. Probably an outdated regex on user agent?
Amazing how little PHP can do so much! https://serverless.industries/2025/07/06/antiframework.en.html
I also do 99% of prototyping in PHP.
Fun idea from @christian
Turns out HTTP Host headers can have a trailing dot (totally valid too) and nginx will happily forward it to php-fpm making $_SERVER['HTTP_HOST'] have a trailing dot which then fails all WP multisite domain lookups…
First time seeing this on a fresh nginx + php 8.4 setup.
How do you profile PHPStan runs for performance issues?
It appears to be spawning a child process even if maximumNumberOfProcesses is set 1 which makes the core logic invisible to XDebug profiler.
Trying out the new VS Code fork from Google.
Requires Google login to actually use it… not sure I like this direction.

Feels like half the web is down now…
Cloudflare and other MITM proxies with TLS termination have access to your WP usernames and passwords, and every WooCommerce transaction (including customer billing and address data).
