HN discussionI have implemented an interactive demo of this algorithm which can be found at https://nvartolomei.com/weighted-deterministic-aperture/ . Make sure to click "Verbose state" spoiler. Context: Earlier this year I explored using deterministic aperture for balancing writes/appends based on storage usage and implemented a visualization to help explain the algorithm to my colleagues.

HN discussionI love P and have used it for personal projects (like OSWALD^1) and at work (for some Redpanda components). I find it very approachable. If you know some basic theory of distributed systems and have been exposed to actors and state machines before, you should be able to have some non trivial models in a few days at days. Things get slightly more complicated when you begin to ask yourself whether or not you have vali…

HN discussionA “note taking” app after spending years looking for “the right one”. Nothing ground breaking, similar to most other “connected notes” apps but with one small difference: everything is built for my brain workflow rather than the other way around. https://nvartolomei.com/omniverse/ Maybe, one day, after I’m satisfied with its functionality I’ll make it open(-source). For now, in the interest of keeping friction low,…
