Hello #SmashingConf NY folks! Be sure to sign up for this FREE lunch session with Tim Kadlec (@tkadlec). Tim will give a tour of new #webperf metrics + how to use them to home in on which optimizations will make your pages faster (and which ones won't). smashingconf.com/ny-2024/lunch-…
Err...this is gonna sound crazy, but I'm pretty sure AWS is...randomly deleting dynamoDB items? My app has one & only one point where it deletes items and I can see no record in CloudTrail of anything being deleted, yet every day a couple random items just...aren't there anymore
me anytime I try to figure out how to accomplish anything in the AWS UI
ok hold up how long has this been there without me noticing chrome drawing a red line between style recalc and the method that triggered it in their flame charts

Keeping your site fast is a crucial endless game. Yet it's perilously easy to lose focus. @tkadlec uses the analogy of guardrails (automated testing & alerts) and breadcrumbs (deployment tracking) to make #webperf more visible throughout the dev process. speedcurve.com/blog/continuou…
NEW! Based on your feedback, we've expanded your capabilities for on-demand testing! This how-to post covers: 🟡 Scheduled vs on-demand tests 🟡 Run on-demand tests for site or custom URL 🟡 View & compare test details 🟡 Group tests as a deploy speedcurve.com/blog/on-demand… #webperf
Site speed isn’t something you fix once and walk away from. @tkadlec offers pro tips on how to set up continuous monitoring – as part of your CI/CD process – so you can fight regressions and stay fast. speedcurve.com/blog/continuou… #webperf #sitespeed #pagespeed #cicd
Kind of snuck under the radar, but love that @SpeedCurve has navigation types as a filter now. Extremely useful!!
Love me some server timing!
