Linux va bien : https://www.junauza.com/2026/03/linux-won-and-nobody-noticed.html

Linux a gagné la guerre avec des changements silencieux qui se sont réalisés au cours des années. L'OS fait + de bruit ces dernières années car il grapille des parts de marché du desktop, mais pour le reste, Linux se porte à merveille depuis un bon bout de temps.

As questions about the previous post on #RISC_OS today's and tomorrow start flowing, I posted a new article with some answers to some of those. Please remember this is an open discussion, so if I have made errors please send me the corrections, thank you!

RE: https://mastodon.social/@rperezrosario/115690942091524650

Wow! Amazed that 62% of 7,280 people mainly use GNU Linux/ UNIX as their “personal time”operating system (ie when they have a free choice). Decent sample size but how different/similar is Fedi to the rest of the world? And has this percentage changed recently (ie because of recent events)? Fascinating developments… love to know more. 😊

Ubuntu в Windows Subsystem for Linux (WSL)

Если у Вас в качестве основной или единственной операционной системы стоит Windows, то самый быстрый и удобный способ начать пользоваться Ubuntu - встроить ядро Linux прямо в Windows. Эта встроенная в операционную систему Windows функция позволяет обойтись без монитора виртуальных машин (гипервизора) или мильтизагрузки (dual-boot). Ядро Linux запускается на облегчённой служебной виртуальной машине на основе компонентов гипервизора Hyper-V. Таким образом после установки дистрибутив Linux оказывается полностью интегрирован в Windows, и позволяет пользоваться преимуществами обеих ОС при разработке с минимальными затратами в аппаратных, временных и человеческих ресурсах. С помощью WSL можно даже запускать графические приложения Linux ( см. примечания ), но, скорее всего, Вам это не понадобится.

And while on the ROOL forum people are posting of using Linux, no resurrect RISCOSE, no something else, no nothing is possible for #RISC_OS is the typical old school mindset, #ProjectMerlin runs now on #AArch64, because if we don't start doing something, nothing will ever happen.

While I really like GNOME and its focused approach and environment, I can't help but enjoy KDE as much if not more with its customization options.

Figured I'd change my desktop layout for a change and came with GNOMEsque / macOS / Win11 inspired one in about 5/10 minutes. The top bar only appears if the mouse hovers over it, making the desktop in general very minimalistic.

The only problem comes with maximized windows, sometimes the top bar comes up if I want to close a window, for instance. Still trying to find a solution for that.

What are your favorite desktop environments and why?

Язык программирования C, твой путь начинается здесь, самурай

Приветствую! Когда мне сначала просто захотелось, а потом потребовалось и для работы изучить C++, я сильно удивился, что информации касаемо пары C/C++ информации вроде много, но она уж слишком сильно не структурирована и не систематизирована. Одно лишь объяснение указателей мне потребовалось очень много времени искать, потом я понял что такого нет. В интернете есть много объяснений и информации, но это все либо рерайт чужих статей либо просто бессвязный бред где порой кажется что сам человек не проверяет информацию либо просто сам не знает. Да и честно говоря очень мало понятных и рабочих кусков кода с объяснением решения, которое можно было бы протестировать на работоспособность. Поэтому я решил здесь в данном блоге (Habr идеальное место для этого) собрать в кучу как свои мысли так и свой опыт. А также опыт других людей которые также использовали данный инструмент в своей работе или просто как хобби. Также стоит отметить, что на мой взгляд для изучения C++ надо начать именно с C, но применять его врятли получится потому что как бы C не был хорош, все же на фоне C++, для современных задач он не полноценен (но тут я сразу уточню, что технология превосходная и я до сих пор удивляюсь как кто-то смог создать подобный язык, с настолько простым и удобным функционалом, который используется и сейчас, но в современной разработке он не функционален, хотя дальше я опишу сферу применения данного языка программирования).

An Elf Odissey! #dreamos64 I recently added support for basic ELFs in my hobby #kernel but, it required me to dig into some very obscure issues caused by some changes in llvm and their linker.

Basically the introduction of large sections in #llvm broke the grub image, and caused more problems to my kernel.

I posted all the details of my debug process in my free #kofi post here: https://ko-fi.com/post/Finally-Dreamos64-is-officially-running-an-ELF-Exe-B0B41AYZW0

#Linux operating systems are not keeping up with new apps and gooey graphics.

People can't give up time to use the command line to keep modern features working.

Text-based User Interface command line apps and multiplexers to help?

Mac OS has been described as a fancy BSD GUI and MS Windows as a straight-jacket ecosystem. Point and click tropical beaches.

Today a new version of the printed version of "Osdev Notes" has been released! :)
More info in my free #kofi post: https://ko-fi.com/post/Osdev-Notes-New-printed-version-released-U7U5199LOA
The printed version is available here:
https://www.lulu.com/search?sortBy=RELEVANCE&page=1&q=osdev+notes

Major update is the replacement of the "Stivale 2" protocol with the "Limine Protocol".

The project as usual is on github:

Адаптируем фаззинг для поиска уязвимостей

Фаззинг — очень популярная методика тестирования программного обеспечения случайными входными данными. В сети огромное количество материалов о том, как находить дефекты ПО с его помощью. При этом в публичном пространстве почти нет статей и выступлений о том, как искать уязвимости с помощью фаззинга. Возможно, исследователи безопасности не хотят делиться своими секретами. Тем интереснее рассмотреть эту тему в данной статье.

🌟 Love the concept of Long Term Support (LTS) releases for operating systems! Especially for servers. It's fantastic that they offer nearly a decade of support, perfectly matching the typical lifespan of hardware. This means we only need to think about major software upgrades when it’s time for a hardware refresh. What are your thoughts on LTS?

An update to my book "Osdev Notes" has been released.
This update contains as usual lot of typo fixes, but it also expand few areas: The "Syscall Example" chapter and the "Elf" section.

As usual the printed book is available on lulu: https://www.lulu.com/search?sortBy=RELEVANCE&page=1&q=osdev+notes&pageSize=10&adult_audience_rating=00

And the link to the github release is here: https://github.com/dreamportdev/Osdev-Notes/releases/tag/v1.3 As usual the book can be downloaded for free. #osdev #selfpublishing #programming #operatingsystem #kernel #assembly #x86_64 #operating_systems
