Phoronix - 26. Červen 2020 - 17:39
More than a decade ago Fedora was routinely trying to pursue the Btrfs file-system by default but those hopes were abandoned long ago. Heck, Red Hat Enterprise Linux no longer even supports Btrfs. While all Red Hat / Fedora interests in Btrfs seemed abandoned years ago especially with Red Hat developing their Stratis storage technology, there is a new (and serious) proposal about moving to Btrfs for Fedora 33 desktop variants...

Svět se mění a pro Intel v něm možná začíná být těsno - 25. Červen 2020 - 23:00
[7 minut čtení] Světu fotografie celých 100 let kraloval Kodak. Dnešní děti jej vlastně ani neznají. Světu procesorů zase přes 40 let kralovala společnost Intel. Dnešní děti tuhle firmu dobře znají. Zatím. Tohle ohlášení, které je staré pár dní, by bývala byla pecka, kdyby si oněm neštěbetali vrabci na střeše už pár let. Jobs vždycky citoval Alana Kaye, který tvrdil, že společnost, která to myslí vážně se softwarem, by si měla vyrábět vlastní hardware. Jobs zcela jistě směřoval firmu Apple k tomuto ultimátnímu cíli, kterým se nakonec v těchto dnech ukazuje sice značná nezávislost, ale stále určité područí dvou (případně tří) firem, na kterých bude Apple i po přechodu na ARM závislý.
