MRI RubyのGlobal VM Lock（GVL）は、何かと説明が的外れだったり誤解されたり批判にさらされたりしがちです。My article in 日本語, translation by @email@example.com https://techracho.bpsinc.jp/hachi8833/2020_05_27/92042
Tune in on Tuesday, June 2nd for a lightning talk by @firstname.lastname@example.org on building out mental models for web application performance and scaling https://www.meetup.com/tokyotechmeetup/events/270419853/
🚀🚀🚀 Malicious packages in @email@example.com? Not anymore! I've built and OSS supply chain security platform for Ruby: https://diffend.io - it acts as a free and public proxy for RubyGems blocking any malicious gems from even being downloaded! MUCH more to come!
maybe you could reify providers, then reify "lang stacks" which just represent the ~5 bash commands you need to execute to get a language running on a fresh ubuntu box. so the final command would be like $ my-command up --lang=ruby --provider=do
it probably needs 3-4 more hours of polish and it would actually be a pretty useful set of bash scripts for standing up remote dev boxes I think.
I made a bash script that glues Terraform, Digital Ocean and Mutagen together to give you a pop-up remote Ruby development environment w/port forwarding/filesync from the current directory: https://gist.github.com/nateberkopec/5e1d81c8b5f4865c19e18ecae73c77ae Using it to stand up temp Linux dev boxes for Puma work
Yikes, if you're using Docker for Ruby apps in non-public environments (i.e. in dev), looks like there's a security setting you can change to make your app up to 2x faster https://mamememo.blogspot.com/2020/05/cpu-intensive-rubypython-code-runs.html
TIL @firstname.lastname@example.org wrote an entire collection of several dozen troll system performance tools: http://www.brendangregg.com/specials.html
This expresses a feeling I've had for a while: https://lobste.rs/s/dyeuqm/i_want_own_database_my_apps_use I want SAP but for personal data. Everyone uses the same DB, and I control it. Maybe impossible. Maybe too complicated. But feels, at least, _possible_.
