To all the times I'd watch Nadal's forehand before practice, switched my grip to exactly match his and smile when in my mind the shot I hit exactly matched his - thanks @RafaelNadal will miss watching you play 🥹

Rafa Nadal hits an OUTRAGEOUS forehand down the line winner against Novak Djokovic at the Six Kings Slam. Might be the last singles match of his career. But Rafa’s tenacity remains unmatched in every sense. Greatness. 🇪🇸🥹

My first manager at Uber started a GitHub page back at the time with resources to become a more proficient developer - ones he personally found helpful (he did not have a CS degree). I realized he is *still* updating it, 7 years later! A neat list: github.com/charlax/profes…

Who knew SSH had an interactive TUI help interface and can negotiate tunnels via the menu!

ssh has secrets. Too many to share in one tweet. One of which is how it acts as a serial-line processor for secret keyboard functionality you probably never knew about. For example, why, when you press ENTER and then ~ immediately after, does the ~ not appear right away? Thread…

hang on, did @Ledger fire the employee after they fell for the phishing link that led to today's attack, or do they not remove employees from the company's NPMJS team when they leave the company? 🤔 twitter.com/Ledger/status/…

Adding to the list of things you can do with eBPF in Linux is writing a task scheduler: lwn.net/Articles/92240…, this custom scheduler runs in a class between SCHED_IDLE and SCHED_NORMAL. There is also a basic reference implementation. #bpf #linux #CPU

15 years ago, I helped design Google Maps. I still use it everyday. Last week, the team dramatically changed the map’s visual design. I don’t love it. It feels colder, less accurate and less human. But more importantly, they missed a key opportunity to…

How Does Chromium affect root-server DNS traffic? What are those weird queries that are sent out by Chromium and why? blog.apnic.net/2020/08/21/chr… #dns #chromium #google


We all know that the DNS root servers use Anycast to help scale their query load, but what problems got them to that stage? (answer might surprise you) blog.apnic.net/2020/09/28/sca…… and how is the DNS protocol evolving to help curb the load? #dns #sre #anycast #ietf


Whatever happened to the @highscal's blog? It doesn't seem active any more.
