Chińscy naukowcy opracowali najlepszy od 41 lat algorytm wyznaczania najkrótszej ścieżki w grafie! Zespół z Tsinghua University przełamał barierę sortowania Dijkstry. To pierwsza poprawa od 1984 r. Nowy algorytm działa w czasie O(m*log⁡2/3n). Co to może dać? Szybsze GPS, routing internetowy i planowanie tras w logistyce. W praktyce oznacza to krótsze czekanie na wyznaczenie drogi, mniej korków, tańsze dostawy i sprawniejsze działanie sieci komputerowych. No i konieczność aktualizacji programu studiów informatyki :) arxiv.org/pdf/2504.17033

Slajdy z Damiana i mojego wystąpienia na @WarszawaJUG: mat3e.github.io/talks/spring… Przykładowa aplikacja: github.com/mat3e/downloads-s… Artykuły napisane przez nas w temacie: - paramount.tech/blog/2023/12/… - paramount.tech/blog/2023/12/… #SpringBoot #Java #testing

Good overview - logs, metrics, how they grow over time, APDEX, traces, baggage, APM, OpenTelemetry, events, example @honeycombio walkthrough 👍🏻

JSONPath and each JSONPath lib having its own features 🤯

Somehow I overlooked this gem. I like how fallback logic (if choosing success or failure by default) appeared non-obvious: 1. Success for growth: x.com/GergelyOrosz/status/15… 2. Failure can also break a lot: x.com/GergelyOrosz/status/15… 3. #Uber choice: x.com/wspruijt/status/150331…

I co-authored 2 blogposts on integration tests with #SpringBoot and they got just published: - paramount.tech/blog/2023/12/… - paramount.tech/blog/2023/12/…

TS2419: Types of construct signatures are incompatible. X could be instantiated with an arbitrary type which could be unrelated to Y 😂😭

We run #Coderetreat workshop internally and here are our thoughts, including participant's perspective: paramount.tech/blog/2023/11/… #gdcr2023

Wasn't impressed by GitHub #Copilot so far, but today it really helped when checking Conway's Game of Life for @coderetreat.

... and that's why loose coupling is an important design principle
