Python + bash
Если вам часто требуется запускать shell команды из Python-кода, какой способ вы используете?
Самый низкоуровневый это функция os.system(), либо os.popen(). Рекомендованный способ это subprocess.call(). Но это всё еще достаточно неудобно.
Советую обратить своё внимание на очень крутую библиотеку sh.
Что она умеет?
🔸 удобный синтаксис вызова команд как функций
# os
import os
os.system("tar cvf demo.tar ~/")
# subprocess
import subprocess
subprocess.call(['tar', 'cvf', 'demo.tar', '~/'])
# sh
import sh
sh.tar('cvf', 'demo.tar', "~/")
🔸 простое создание функции-алиаса для длинной команды
fn = sh.lsof.bake('-i', '-P', '-n')
output = sh.grep(fn(), 'LISTEN')
в этом примере также задействован пайпинг
🔸 удобный вызов команд от sudo
with sh.contrib.sudo:
print(ls("/root"))
Такой запрос спросит пароль. Чтобы это работало нужно соответствующим способом настроить юзера.
А вот вариант с вводом пароля через код.
password = "secret"
sudo = sh.sudo.bake("-S", _in=password+"\n")
print(sudo.ls("/root"))
Это не все фишки. Больше интересных примеров смотрите в документации.

📰 Open-Source Nouveau Performance With Linux 7.0 + NVK Mesa 26.1-dev vs. NVIDIA Linux Driver
As a few months have passed since our prior round of testing the fully open-source NVIDIA Linux driver stack with the Nouveau kernel driver and Mesa NVK Vulkan driver plus Zink, here is a fresh round of benchmarks using Linux 7.0 and Mesa 26.1-dev compared to the open-source stack shipped by Ubuntu 25.10 (Linux 6.17 + Mesa 25.2) for showing how far the open-source NVIDIA driver has progressed the past few months.

📰 The Intel Lunar Lake CPU Performance Gains On Linux Over The Past Year
Recently I ran benchmarks looking at the Xe2 graphics performance gains on Intel Lunar Lake over the past year with what's shipped by Ubuntu and comparing against our original tests of the Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition. With those Lunar Lake iGPU benchmarks out of the way, here is a look at how the Lunar Lake CPU performance has evolved on Linux since April 2025.

[$] BPF comes to io_uring at last
Linux 内核的异步 I/O 接口 io_uring 通过两个共享环形缓冲区与用户空间通信：提交队列用于发送请求，完成队列则存放结果。尽管共享内存减少了大量开销，但内核仍需切换至用户空间以处理完成事件并提交后续工作，这仍会产生开销。
Pavel Begunkov 提交的补丁集旨在最小化这一开销。它允许开发者使用 BPF 程序扩展 io_uring 的事件循环，使程序能直接响应完成事件并提交后续工作项，无需切换至用户空间。该补丁集已开发很长时间，现已被内核社区接受。
这一改进将进一步提升 io_uring 的高性能 I/O 处理能力。

[$] Modernizing swapping: introducing the swap table
Linux 内核的交换子系统（swap）是内存管理的关键部分，但代码复杂且性能影响大。在 2025 年 Linux 存储、文件系统、内存管理与 BPF 峰会上，Kairui Song 提出了一个简化和优化交换代码的计划。该计划的第一部分已在 6.18 内核版本中合并，由 Chris Li 协助完成。本文介绍了 6.18 中的初步改动，为后续更深入的优化奠定了基础。
