Jsongrep je open-source nástroj, který efektivně prohledává JSON dokumenty (editovat je neumí). Kompiluje regulérní jazyk dotazu do podoby deterministického konečného automatu (DFA), díky čemuž prochází strom JSON dokumentu pouze jednou a je v tom tedy rychlejší než jiné nástroje jako jsou například jq, JMESPath nebo jql. Jsongrep je napsaný v programovacím jazyce Rust, zdrojový kód je dostupný na GitHubu.

Mozilla a společnost Mila oznámily strategické partnerství za účelem rozvoje open source a suverénní AI. Cílem je ukázat, že open source AI může konkurovat uzavřeným systémům. Obě organizace chtějí posílit technologickou suverenitu a snížit závislost na hrstce velkých technologických firem.
Adam Rice předvedl, že pomocí DNS lze distribuovat a spustit kompletní hru DOOM. Rozdělil WAD soubory a binárky do téměř 2000 DNS záznamů v Cloudflare zóně (jeden TXT záznam v DNS může nést okolo 2000 znaků textu). Ty pak stáhl PowerShellem, dekomprimoval a spustil přímo v paměti počítače bez nutnosti zápisu na disk, což prakticky dokazuje, že DNS může sloužit jako distribuované úložiště dat a možný kanál pro načítání kódu. Repozitář projektu je na GitHubu.
Dnes a zítra probíhají Arduino Days 2026. Na programu je řada zajímavých přednášek. Sledovat je lze od 17:00 na YouTube. Zúčastnit se lze i lokálních akcí. Dnes v Poličce v městské knihovně a zítra v Praze na Matfyzu.
