W3C RUM Community Group's discussion on HTTP Header Adoption (Timing-Allow-Origin and Server-Timing) was fun! Minutes, slides, recording and transcript are here:

w3c-cg.github.io/rum/meetings/

TLDR: Goal to provide guides on adopting headers, a Server-Timing registry, and outreach to popular 3Ps.

It's more like I'm upgrading my server, PHP and MediaWiki versions and need to debug other code and take over ownership of abandoned extensions!

I was this many years old when I finally learned how to debug PHP "properly" (step debugging via XDebug using VSCode on a remote container). Until now I've only ever debugged PHP via echo or error_log() statements. I've been writing PHP code since ~1998. I'm living in the FUTURE everyone! :P

Painful. You have my empathy Adam! But remember they can't take away the YOU from you. Keep focusing on being the amazing person, developer, advocate you are.

Experimentation in the homelab! Switched from #Prometheus + #Thanos to just #VictoriaMetrics (w/ migration of 2yrs of data), much happier! Prom would die on larger dashboards/queries, OOM. VM is 20% of the size of Prom, and queries insanely fast! 30s+ queries in Prom/Thanos, now taking <1s in VM.

My latest post on the Performance Advent Calendar is now live: calendar.perfplanet.com/2024/when-us...

This one talks about the elephant in the rüm of user interactions.

When users interact

When looking at the Core Web Vitals, we often try optimizing each independently of the others, but that's not how users experience the web. A user's web experience is made up of many metrics, and it'...

In our meeting yesterday, we decided to adopt Element Timing (and the followup Container Timing work) into the working group. CfC coming up!!

We also discussed some upcoming improvements to the crash reporting API (still in incubation).

So even though you've satisfied all of those conditions, there's a hidden condition of characters you can't use?

You know, because, you can't be trusted to use -

Would you want core web vitals In Safari? Can you help me understand how you would use them and why numbers in one browser isn’t enough?

(These may sound like silly questions, but I’d love to understand *your* specific context and use cases)

Yes! Our RUM customers (mPulse) repeatedly ask for CWV support in Safari and wonder why the data isn't there. They've invested in tracking CWVs because they're easy to understand and help measure UX directly. As sites optimize for them, I don't want that to be biased towards Chrome/Firefox only.
