Beautiful weather yesterday on the roof of the @ATLTechVillage when Craig Hyde told all of @TeamRigor the great news: Splunk is acquiring Rigor! "This Opportunity is HUGE" indeed!

@krebs_adrian Brin and Page's Stanford paper "The Anatomy of a Large-Scale Hypertextual Web Search Engine" includes "Appendix A: Advertising and Mixed Motives" with this fun quote:

@kahrens_atl I've got a friend you should talk to. What's the best email for you?

We are right in the middle of Google's Web Vitals search rollout. Are your perf metrics still red? 🤬 Are you still confused about TBT and LCP? Ready to be faster? I'm hosting a Web Vitals webinar tomorrow

@bluesmoon ffmpeg is, quite simply, amazing

This week’s major internet outage impacted wide swaths of the web. So what can #IT and #DevOps teams learn from the event? Splunker Billy Hoffman shares how to leverage #observability to reduce the future impact of an outage here: https://t.co/WimtjvsPsy #SplunkO11y

Odd HTTP question. How is expiration computed for responses that have a Cache-Control: max-age, but do not have a Date header? example: https://t.co/qMflrXI9hm (cc: @mnot @paulcalvano)

😮 WebPageTest's new license is... ... not good for those vendors who just wrapped WPT in a pretty UI. They are stuck using an older WPT, and having to forward patch it, without using the new source going forward. 🤮https://t.co/j2QtrD1UXK

@HenriHelvetica wrote a fantastic chapter on page weight in the @HTTPArchive Web Almanac where you can dive deeper into these stats - https://t.co/BS1U7X33Dm

Words I never thought I would say, but am: Nice job @Mike_Pence

[Billy Hoffman @zoompf]

@csswizardry Is there a good generic way to determine <img> or <picture> tags that should have lazy load? Seems like a "humans know it quickly but programs don't" issue. I've been toying with having some % of the tags having the attribute, or looking at elements outside the initial viewport.

Evergreen browsers + security headers have been such an incredible benefit. Glad to see it accelerating

[Lukas Weichselbaum @we1x]

PoC. First Google applications are deploying *all* new web platform security features (+new isolation headers!) we presented last year at Google I/O.
Isolation headers where quite straight forward to deploy
Dial in to @arturjanc's @LocoMocoSec talk to learn about isolation issues

[Lukas Weichselbaum @we1x]

@arturjanc's @LocoMocoSec talk about isolation issues in the web platform is happening today!

Love this post about CLS and the actual impact on user behavior. Remeber: better perf/UX is not the goal, improving business metrics is the goal, and you need to always evaluate performance metrics/changes through the lens of the bus. metrics (conversions, bounces, etc)

[Tammy Everts @tameverts]

I've spent a fair bit of time wrapping my head around CLS and looking at a lot of data. Here's my take on these vital (to me) questions:

🔶 What does CLS mean in terms of #UX?
🔶 Does it correlate to user/biz metrics?
🔶 How much should we care?

Five years ago, Rigor acquired Zoompf. Now @splunk is acquiring Rigor. It's a web performance turducken!

[Billy Hoffman @zoompf]

@LandonB32 @TeamRigor @conarro @splunk Those pictures are fantastic!

[Billy Hoffman @zoompf]

@wayt @TeamRigor @craighyde Thanks for making the process easy and not overwhelming Wayt! Being on an M&A Zoom call with 30 lawyers from the other side, it's easy to get down rabbit holes. You really helped us surface what was important.

[Billy Hoffman @zoompf]

@JonnyBird @craighyde @TeamRigor Thanks Jon. Rigor's come a long way from those tiny offices on the 2nd floor of the pre-renovated ATV! Thank you for the early expose via the Atlanta Startup Village!

[Jon Birdsong @JonnyBird]

10 year over night success! So inspired by @craighyde and the entire @TeamRigor team: https://t.co/BuBkSdHNXU well done!

Congrats @craighyde and @TeamRigor! 👏👏👏
