AI Helped Uncover A "50-80x Improvement" For Linux's IO_uring

19 février 2026 à 17:42
Linux block maintainer and IO_uring lead developer Jens Axboe recently was debugging some slowdowns in the AHCI/SCSI code with IO_uring usage. When turning to Claude AI to help in sorting through the issue, patches were devised that can deliver up to a "literally yield a 50-80x improvement on the io_uring side for idle systems." The code is on its way to the Linux kernel...

Gigabyte MZ33-AR1: A Uniquely Positioned AMD EPYC 9005 Motherboard For Open-Source Firmware

19 février 2026 à 16:14
The Gigabyte MZ33-AR1 is a single socket AMD EPYC 9004/9005 E-ATX server motherboard for those wanting up to 24 RDIMMs, dual 10 Gigabit LAN, and plenty of storage potential via six MCIO connectors and four PCIe Gen5 x16 slots. Beyond offering nice capabilities for this modern AMD EPYC server motherboard at a ~$700 USD price point, it's uniquely positioned for an open-source firmware future thanks to ongoing work around AMD openSIL and hopefully followed by OpenBMC.

Mediatek MT7902 WiFi Finally Seeing Open-Source Linux Driver Activity

19 février 2026 à 15:03
When searching for "MT7902" and "Linux" there is no shortage of users asking about Linux driver support for the Mediatek MT7902 WiFi chipset or users complaining about their MT7902 WiFi not working under Linux with that chipset found in numerous laptops in recent years. Fortunately, there is finally Linux driver support for the MT7902 surfacing for review on the Linux kernel mailing list...

SmartOS is designed to be particularly suitable for building clouds and generating appliances.

Physiocab : un logiciel libre de gestion pour kinésithérapeutes

19 février 2026 à 14:42

Physiocab est un logiciel libre de gestion de cabinet de kinésithérapie, développé sous licence Affero GPL 3.0 et hébergé sur Codeberg. Le projet est porté par la société Allium SAS, dans le cadre de la plateforme communautaire Kalinka, dédiée aux kinésithérapeutes francophones.

Le projet vient de passer en beta publique (v0.9) et cherche des testeurs et contributeurs.

Pourquoi un logiciel libre pour les kinés ? Le secteur de la santé libérale souffre d'une offre logicielle dominée par des solutions propriétaires onéreuses, souvent opaques sur le traitement des données de santé. Physiocab propose une alternative : un code auditable, des données stockées localement sous la responsabilité du praticien.

Fonctionnalités

La beta couvre déjà un large périmètre fonctionnel :

  • Planning hebdomadaire en drag & drop, avec export PDF et gestion des semaines exceptionnelles, particulièrement orienté vers les kinés intervenant en multi-établissements.
  • Bilans Diagnostiques Kinésithérapiques (BDK) avec tests standardisés (TUG, Tinetti, Handgrip, EVA, évaluation du risque de chute…), export de PDF et historique comparatif.
  • Suivi des séances avec de multiples exercices structurés (équilibre, force, endurance, mobilisation), chronométrage automatique et calcul de progression.
  • Application tablette en PWA : fonctionne hors connexion grâce à un Service Worker, s'installe sans passer par un store, interface optimisée tactile.

Stack technique

Backend : Python 3.10+
Base de données : PostgreSQL 12+
Frontend tablette : PWA (Progressive Web App)

L'application est multi-plateforme côté client (Windows, macOS, Linux, iOS, Android). La communication entre l'appli de bureau et l'appli PWA se fait de manière directe via PeerJs. Cette méthode ne nécessite pas de préparation contraignante comme l'ouverture de ports.

Les données sont stockées localement, ce qui implique que le praticien reste maître de ses sauvegardes et de sa conformité RGPD.

Le logiciel a été testé par un kinésithérapeute en situation réelle plusieurs jours d'affilée.

Modèle économique

L'utilisation est gratuite, sans limite dans le temps et sans frais cachés, la licence Affero GPL 3.0 en étant la garantie. Un support payant sur devis est proposé pour les praticiens souhaitant une installation assistée, une formation à distance, des développements sur mesure ou un audit de sécurité.

Simdjson Shows More Speed-Ups Possible For SIMD In JSON Parsing: Another 30% Boost

19 février 2026 à 12:05
Simdjson is the open-source project for high performance JSON parsing by leveraging SIMD instructions for "parsing gigabytes of JSON per second." Notably it showed years ago the huge performance advantage to using AVX-512 in JSON parsing for surprisingly big benefits. Simdjson has continued advancing since then with various optimizations over the years and today is out with simdjson 4.3 that brings yet more SIMD optimizations...

Linux Still Working To Clean Up The Realtek RTL8723BS 802.11b/g/n WiFi Driver In 2026

19 février 2026 à 02:25
Introduced to the Linux 4.12 kernel's staging area back in 2017 was the Realtek RTL8723BS WiFi driver. The Realtek RTL8723BS is an 802.11 b/g/ SDIO WLAN adapter with Bluetooth 4.0 connectivity too. In the nearly decade since this driver was added to the staging area, it's continued to be cleaned up and with the Linux 7.0 merge window there is yet again a lot of work on cleaning up this WiFi driver for the old Realtek hardware...

More ISA Differences Come To Light With The New AMD GFX1170 "RDNA 4m"

18 février 2026 à 23:40
Earlier this month we spotted the addition of a new GFX1170 GPU target in the AMDGPU LLVM back-end. Making this GFX1170 target interesting is that its marked as an APU/SoC part with "RDNA 4m" while being part of the GFX11 series. The GFX11 series is for RDNA3, GFX115x is for RDNA 3.5, and GFX12 is RDNA4. More ISA changes have now been committed to the AMDGPU LLVM back-end that make a few more instruction differences better aligned with RDNA4...

Linux 7.0 Showing Some Early Performance Regressions On Intel Panther Lake

18 février 2026 à 22:00
With the Linux 7.0 merge window beginning to calm down ahead of the 7.0-rc1 release due out on Sunday, one of the areas I was most excited about benchmarking on Linux 7.0 was looking for any performance gains with the new Intel Core Ultra Series 3 "Panther Lake" given ongoing Intel Xe graphics driver improvements and other general kernel optimizations. Unfortunately, at large the Intel Panther Lake performance is moving in the wrong direction with the early Linux 7.0 benchmarking.
