3… 2… 1… REAKTYWACJA! 🚀

Po 7 latach przerwy Poznańska Impreza Wolnego Oprogramowania wraca na Politechnikę! 🔥

📅 7 czerwca 2025
📍 Centrum Wykładowe Politechniki Poznańskiej

To będzie XIV edycja P.I.W.O. Wracamy z nową energią, świeżymi pomysłami i jeszcze lepszą organizacją!

Za reaktywacją imprezy stoi grupa @hspoz, KN PUTrequest_ oraz KN Linux Academic Group. Wspierają nas także: @PLUG_pl oraz @ftdl.

Hard times ahead for Americans. It looks like that good karma is running out, although it's still nothing compared to some other populations in the world.

I hope some of them rediscover kindness and empathy, and realize that selfishness and xenophobia put them where they are headed now.

Make VoWiFi calls from an open source client using asterisk: https://osmocom.org/news/297 - osmocom main contributor @sysmocom has recently released a forked version of asterisk that can be used to make VoWiFi calls using nothing but FOSS, a smart card reader and a SIM card. #foss #opensource #telecom #3gpp

This is Sway in HDR mode, but unlike last time, there are no hacks nor tricks. It supports both SDR and HDR content on both SDR and HDR outputs. Phew!

Want to try it out? Instructions here: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/5002

I'm not sure which of you need to hear this, but:

If you push yourself to your limits and burn out for a company, you are trading years of your future productivity for minor gains in the present.

Burning out will _fuck you up_, it's like brain fog or depression, and it takes years to recover

When discussing digital independence, keep in mind that it works differently for proprietary products and FOSS.

To achieve independence from a proprietary software or service you need to _get out_ - stop using it, create and switch to an alternative.

To achieve independence with FOSS projects, you need to get _in_ - invest resources (human, infra,.. not money) in the project and its ecosystem, so that it becomes yours.

Congratulations to Gints Zilbalodis and the entire Flow film crew for the Academy Award win!

Flow is the manifestation of Blender’s mission, where a small independent team is able to create a story that moves audiences worldwide.

Thank you for the shout out! 🧡 #b3d

Discrete Fourier transform is one of the most important algorithms in computing but it's also one of the worst-explained ones. You can go through pages of search results and not find a single accessible explanation of *why* it works.

A while back, I put together an explainer. I don't think it ranks highly in search, but if you want to understand the algorithm behind a lot of multimedia compression algorithms & filters, here's your chance:

Of all the things I've done in my career, this is probably the one I'm the most proud of.

When me and two others at Intel started working on the Vulkan driver, Mesa had a reputation for being behind on everything. The Intel drivers were still on OpenGL 3.3 (fp64 was a pain), OpenGL ES 3.1 or maybe even 3.0, and perf okay but kinda meh. I think there might have been a driver or two in Mesa exposing GL 4.x at that point but, as a project, we were still a ways from full OpenGL 4.5.

With Vulkan, we jumped the line and had Vulkan 1.0 conformance on Intel on launch day. It was a hell of a lot of work (I worked 80+ hours/week that last month or two) but we got there. The driver branch we dropped that day was pretty shaky and it was missing a lot of features but we were there. It took a year or two to get to where we had decent perf, working games, and feature parity with the hardware. But that was okay because there were only two titles that came out that first year and getting them working was the important bit.

Then Vulkan 1.1 came out and we were there with a day-0 driver again. This time, without missing any interesting features. Then 1.2 and 1.3 and now 1.4. With every new version, more drivers joined the train. When Vulkan 1.4 launched, there were 5 different Mesa drivers that landed MRs on to enable Vulkan 1.4 on launch day.

This has totally changed the conversation about open source graphics. When I started, everyone scoffed at Mesa. Today, the speed at which we're able to implement features and launch new API versions is the envy of the graphics industry. We're still not totally caught up everywhere—NVK and PanVK still need work and etnaviv Vulkan doesn't exist—but we're going toe to toe with the proprietary driver teams across most of the industry. The fact that Linux Vulkan drivers are being hammered by most of Valve's library via DXVK and VKD3D means the Mesa drivers are often more stable and robust than their closed source or Windows counterparts.

It's a totally different world for 3D graphics now than it was a decade ago.
