Byla vydána nová stabilní verze 24.05 linuxové distribuce NixOS (Wikipedie). Její kódové označení je Uakari. Podrobný přehled novinek v poznámkách k vydání. O balíčky se v NixOS stará správce balíčků Nix.
Byla vydána nová verze 1.48.0 sady nástrojů pro správu síťových připojení NetworkManager. Novinkám se v příspěvku na blogu NetworkManageru věnuje Fernando F. Mancera. Mimo jiné se v nastavení místo mac-address-blacklist nově používá mac-address-denylist.
Před 25 lety, 31. května 1999, započal vývoj grafického editoru Krita (Wikipedie). Tenkrát ještě pod názvem KImageShop a později pod názvem Krayon.
Farid Abdelnour se v příspěvku na blogu rozepsal o novinkám v nejnovější verzi 24.05.0 editoru videa Kdenlive (Wikipedie). Ke stažení brzy také na Flathubu.
David Revoy, autor mj. komiksu Pepper&Carrot, se rozepsal o své aktuální grafické pracovní stanici: Debian 12 Bookworm, okenní systém X11, KDE Plasma 5.27, …
Wayland (Wikipedie) byl vydán ve verzi 1.23.0. Z novinek lze vypíchnout podporu OpenBSD.
Craig Loewen na blogu Microsoftu představil novinky ve Windows Subsystému pro Linux (WSL). Vypíchnout lze GUI aplikaci pro nastavování WSL nebo správu WSL z Dev Home.
V sobotu 1. června lze navštívit Maker Faire Ostrava, festival plný workshopů, interaktivních činností a především nadšených a zvídavých lidí.
Webový server Caddy (Wikipedie) s celou řadou zajímavých vlastností byl vydán ve verzi 2.8 (𝕏). Přehled novinek na GitHubu.

Při měření pomocí reálných aplikací SMB/FTP přenosu zkrze VPN rychlost značně oscilovala, ale na výrazně vyšších hodnotách (až násobně) než u iperf3 benchmarku. Vliv latence tam určitý je, s rostoucí latencí rychlost přenosu klesá, ale méně výrazně.
