Svobodný software

[5 minut čtení] Dnes si povíme o úskalích her na pískovišti, osvěžíme si své vědomosti o Století páry, zadními vrátky vklouzneme do ZOO, zjistíme, že v ukrajinské elektrárně nejsou jen hřivny a zakážeme si nechráněné WiFi. Výzkumníci z londýnské firmy Cyjax po tři dny analyzovali soubory zaslané do tří nejmenovaných sandboxů k analýze a zjistili, že řada organizací neřeší fakt, že se jedná o dokumenty obsahující citlivá data a bez obav odešlou své faktury, objednávky, životopisy, fotografie osobních průkazů a pasů a jiné důvěrné materiály. Odesílajícím organizacím vůbec nevadilo, že všechny analyzované sandboxy umožňují stažení jakéhokoliv nahraného souboru kýmkoliv z Internetu.

[4 minuty čtení] Radeony dostanou změnu frekvencí i s více monitory, Ubuntu se zbaví Qt4 před 20.04 LTS, AMD Ryzen 5 3400G na Linuxu, příští desktop CPU Intel si vyžádají novou desku, nepřinesou ale téměř nic nového. Osvícení uživatelé mohou začít jásat. Nové vydání desktopu Enlightenment 0.23 značně vylepšuje podporu Waylandu. Pravda, věci asi nejdou tak hladce jak by šly, kdyby Samsung nezrušil svoji Open-Source Group, kde spousta vývojářů pracovala Enlightenmentu, ale nevadí.

Mesa's RADV Radeon Vulkan driver just saw a big performance optimization land to benefit APUs like Raven Ridge and Picasso, simply systems with no dedicated video memory...

LG Electronics has been exploring improvements around hibernation/suspend-to-disk to speed-up the Linux boot process for consumer electronics rather than performing cold boots and as part of that is working towards upstream optimizations...

This week saw OpenGL 4.6 support finally merged for Intel's i965 Mesa driver and will be part of the upcoming Mesa 19.2 release. Not landed yet but coming soon is the newer Intel "Iris" Gallium3D driver also seeing OpenGL 4.6 support...

While called the Open-Source Summit, the event is primarily about Linux as after all it's hosted by the Linux Foundation. But at this week's Open-Source Summit in San Diego, Deb Goodkin as the executive director of the FreeBSD Foundation presented. Deb's talk was of course on FreeBSD but also why FreeBSD and Linux developers should work together...

Taking place back in May at the beautiful Skamania Lodge in Washington was Intel's OSTS 2019 for their annual Open-Source Technology Summit that traditionally was internal-only but has begun opening up including allowing external participants this year. I was at OSTS 2019 and it's by far my highlight of the year with many really great sessions and a lot of useful networking at the event. Intel's open-source team has now shared some video recordings from this open-source/Linux event...

AMD Raven Ridge APUs were a rough launch particularly on Linux where even with the latest motherboard BIOS updates and Linux kernel I am still hitting occasional stability issues, so when the opportunity arose recently to try out the Ryzen 5 3400G as the successor in the Picasso family, I was interested. Fortunately, AMD Picasso APUs have proven to be in better shape on Linux so here is the initial round of performance tests for those interested in the AMD Linux performance on Ubuntu.
