Bruarfoss is one of many hidden (turquoise) gems in Iceland.. a little out of the way, but it was so worth the trek!

Back from an unforgettable trip to Iceland. Captured this one on a hike in Þórsmörk... Black lava ridges, neon green moss, glaciers, and beautiful waterfalls! Many more photos to come... :-)

there are dedicated sites that turn youtube videos into gifs (imgur, gfycat) and then turn the gifs back into mp4/webm to run them smoothly inside browser. it's hilarious. i do wish g+ would start converting animated gifs to videos for better delivery over browser and app like facebook/twitter.

Facebook is using h2 server push to optimize image+video delivery: bit.ly/2cQ5qNV.

15% improvement in TTFB for images -- nice perf win!

Too bad the images they're delivering are horribly compressed and look awful. I don't know why anyone would upload photos to Facebook.

You want magic based on the idea of reverse debugging in gdb? Try 'rr' (https://rr-project.org/). 'rr record a.out' then 'rr replay'

+Andrea Pernici can't speak on behalf of the search team, but my speculation is that you'll find the same rules for desktop in the future too. This just happens to be a much more painful experience for users on mobile, hence the focus.

Automatic responsive images with Client Hints: http://bit.ly/2b2SPR6 - the future is here! Well, in Chrome at least.

Cloudinary team is doing great work. This is exactly what we had in mind when designing and building CH.
