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)
Cool to see this blog from Meta eng on adapting the @ApacheKudu raft implementation to run their MySQL replication! engineering.fb.com/2023/05/16/dat…
Happy to see the open source release of the Python "causalimpact" library: github.com/google/tfp-cau… - very useful tool for evaluating impact of software optimizations when A/B simultaneous tests are not possible.
My favorite Cellar Tracker feature is definitely "Un-drink Bottle". I wish that option were available in real life.
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.
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
