Zen 1 EPYC versus Zen 5 EPYC: dvojnásobný výkon, poloviční spotřeba Dělí je osm let, ale jinak jsou si procesory EPYC, které nyní Phoronix porovnal v testu, velmi podobné. Jak Zen 1 EPYC 7601, vlajková loď z roku 2017, tak současný Zen 5 EPYC 4545P, jsou šestnáctijádrové procesory od AMD. Pokrok za osm let nastal, je ale dostatečný?

Zakládám si blog na root.cz, protože nechci mít nepořádek na svém webu a také se mi už nechce reagovat na všechny projekty zde v diskusích. Vyzkoušel jsem postupně všechny webové galerie a žádná z nich nefunguje. Měl jsem skvělou a asi 15 let jsem na vlastním serveru provozoval Gallery2 pro PHP 5 a PostgreSQL. Od té doby jen marně hledám. [$] Possible paths for signing BPF programs BPF programs are loaded directly into the kernel. Even though the verifier protects the kernel from certain kinds of misbehavior in BPF programs, some people are still justifiably concerned about adding unsigned code to their kernel. A fully correct BPF program can still be used to expose sensitive data, for example. To remedy this, Blaise Boscaccy and KP Singh have both shared patch sets that add ways to verify cryptographic signatures of BPF programs, allowing users to configure their kernels… Security updates for Monday Security updates have been issued by AlmaLinux (jackson-annotations, jackson-core, jackson-databind, jackson-jaxrs-providers, and jackson-modules-base and libxml2), Debian (distro-info-data, gnutls28, modsecurity-crs, and node-tmp), Fedora (chromium, incus, perl, perl-Devel-Cover, perl-PAR-Packer, polymake, varnish, and xen), Red Hat (kernel, kernel-rt, and rhc), and SUSE (chromedriver, ffmpeg-4, go1.23, go1.24, go1.25, govulncheck-vulndb, himmelblau, iperf, keylime-ima-policy, net-tools, sqlit… Get your all-access pass to career greatness—use code: AUG25 to save 35% today.

Novinky v distribúcii Debian 13 Trixie Dlho očakávaná stabilná verzia linuxovej distribúcie Debian 13 Trixie pridáva veľký počet aktualizácií softvéru.

Ethics over Exploits – Use PureOS over Android/iOS As Purism has been saying for years, the battleground for digital privacy has shifted squarely into our pockets in the form of smartphones. Mobile devices are now (more than ever) the prime targets for sophisticated cyber threats, having a duopoly with centralized control from two vendors; Apple and Google; the problem gets exacerbated.

CDE na OpenBSD, Ubuntu mění přístup k linuxovému jádru Prostředí CDE z 90. let bude portováno do operačního systému OpenBSD. Ubuntu mění přístup k verzím linuxových jader. Přesně 2 roky, 1 měsíc a 29 dní po vydání Debianu 12 „Bookworm“ je tu Debian 13 „Trixie“. Idea - preco si linuxaci nepostavia vlastnu webkameru? Tak som zase dostal napad a musim sa s nim s vami podelit. Potreboval som zistit kto mi ide "do zeli" a tak som z kumbalu vyhrabal staru kameru (046d:092c Logitech, Inc.

Early Linux 6.17 Tests Show Some AMD Strix Halo Performance Improvements & Regressions Even prior to the Linux 6.17-rc1 release on Sunday I already had kicked off some Linux 6.17 Git benchmarking in being eager to see how the performance is beginning to shape up for this next kernel release that is set to power the likes of Ubuntu 25.10 and Fedora 43. There is some good news and bad news with my early testing on the ZBook Ultra G1a for AMD Strix Halo...

The tool was meant to simplify virus scanning but quickly became a flashpoint when a user claimed it produced malware. After defending the code calmly, the developer was nonetheless met with escalating accusations and hostility, leading to burnout. The project is now marked as "not maintained,"… Linux Address Space Isolation "ASI" Revived After Lowering 70% Performance Hit To 13% Several years ago Google engineers began exploring address space isolation for the Linux kernel and ultimately proposing Linux ASI for better dealing with CPU speculative execution attacks. While the hope was it would better cope with the ever growing list of CPU speculative execution vulnerabilities, the effort was thwarted initially by I/O throughput seeing a 70% performance hit. That level of performance cost was unsustainable. But now that I/O overhead has been reduced to just 13%... |
