Anyone else having flashbacks to early X11 experiences with this new twitter logo? looks an awful lot like `xlogo`

uarch experts: do not-taken forward branches (eg to exceptional paths never expected to be taken) pollute BTB? Is it better to transform the code to produce an invalid pointer load and catch it in a signal handler? (cc @trav_downs)

Happy to see the open source release of the Python "causalimpact" library: github.com/google/tfp-causal… - very useful tool for evaluating impact of software optimizations when A/B simultaneous tests are not possible.

Any doctors on my Twitter who want to tell me if this ear is infected?

My favorite Cellar Tracker feature is definitely "Un-drink Bottle". I wish that option were available in real life.

Does anyone know where to go in the bay area for urgent (but not emergent) non-COVID health issues when COVID ? Wife dealing with some acute pain,been to ER twice who told her to go PCP, then just had the worst imaginable experience at @SutterHealth

(happily scheduled an appointment in internal medicine despite being COVID . We showed up, called ahead to ask if we should just go on in, and they said "sure!". Checked us in. Then called us on the phone, while we're in the waiting room, to cancel on us. wtf)

Seems ERs won't help for non-emergency issues, primary care won't see COVID ... urgent care questionable ability to do imaging or deeper diagnosis. You'd think in the bay area it might be possible to get better care than this...

It's funny that we now have AIs that can pass Google algorithms interviews, but apparently don't yet have AIs that can take my PDF hotel receipt with 30 line items and itemize it into Concur. Pretty sure the 10 minutes I spent entering $2 tax fees separately was not ROI.

Performance people: is there a secret MSR or something that can clear most/all uarch state and caches? Would love to be able to more effectively benchmark "worst case" executions of a code path

Any Peninsula / Bay Area folks have suggestions for pediatric urgent care that don't involve waiting for hours? No one has appointments and "wait for 3 hours with a very sick 2 year old" is not appealing.

The dirty capitalist in me wonders why there isn't a place I can pay too much money and get seen ~right away. Or at least a place where the waiting line is a virtual one and I can just get in the car 30min before our slot is up.

When I interviewed with the Google Spanner team, I asked: "is Spanner done? What's left?" Turns out the answer is (obviously) that infrastructure is never done, and huge changes are still possible. cloud.google.com/blog/produc… details one such transformational change

This migration was already under way when I joined 2 years ago, but I feel proud to have contributed to a few fixes and improvements in my time on the team. If you're looking to make an impact on what's probably the largest OLTP system in the universe, come interview with us!

Anyone aware of research on IO-scheduler-aware caching policies? ie an algorithm that understands that miss cost of 5 adjacent small pages is approximately the same as miss cost of a single page due to IO coalescing? Surprisingly turning up little on this topic
