Mesa 22.2 made the support for hardware acclerated h264, h265, and VC1 optional due to patent claims. Fedora followed suit and is now distributing the version without hw acceleration support for those codecs. This might affect you, if you’re using the nouveau or amdgpu open source drivers. The patent claims seem to make it illegal to use the accelerated drivers in some parts of the world, e.g. the US. But if you live in a part of the world where those claims have no effect, you can get the hw acceleration back using rpmfusion.

While Signal might be the best crypto messenger out there, it is terrible when it comes to simple convenience functions. Sometimes I want to export a chat to archive it or share it with someone who has lost parts of an important conversation due to a key change. But Signal doesn’t offer any official way to create a CSV or even a PDF export. On the other hand, Signal is Open Source , and it’s not very hard to find a way to roll your own export.

Many Hugo templates include reading time or word count as metadata of blog posts. I think that’s pretty handy, and I always enjoy a little heads up - especially on long blog posts where this info helps me to decide if I read it now or save (read ‘kindle’) it for later. But what if your favorite template is missing reading time / word count? It’s pretty simple to add it yourself:

This weekend, I finally came around to enabling IPv6 on my web server. In this post, I describe what I did to get everything up and running on a netcup vServer running CentOS 8, but this should be quite the same for other web hoster services. Motivation My ISP (like many others) primarily uses IPv6 for client IPs and offers IPv4 access via DS-Lite . On random occasions, the IPv4 gateway (DS-Lite NAT) isn’t available, and I can only access the part of the internet which is correctly configured for IPv6 traffic.

Gnome is notorious for reducing user options in the GUI to a minimum. So if you want to use a solid color background instead of a wallpaper, your only option using the UI is to select an image of whatever color you want your desktop background to be. As someone who does not like any distracting elements on the desktop, this feels tedious to me. Fortunately, the functionality is still in the code.

I had a little hickup when I installed Fedora 34 on a machine with an AMD Radeon RX 6700 XT graphics adapter: the boot process got stuck after mounting /tmp. I assume this was caused by KVM, because booting in basic graphics mode worked flawlessly. This is nothing to be worried about. The bootstick obviously just didn’t include the necessary microcode for this rather new GPU. Since Fedora is known for including such microcode in the update cycle of their current releases, I assumed a simple # dnf update might fix this after the installation.

I had a strange problem when I tried to install Windows 10 on a new machine yesterday: I downloaded the Windows 10 ISO from the Microsoft website and used dd to create a bootable USB stick. I could actually boot from the stick but got a weird error message when starting the installation: A media driver your computer needs is missing. This could be a DVD, USB or Hard disk driver.

If your React app’s scrolling seems off, it might actually have nothing to do with scrolling.

I usually recommend Signal as a simple-to-use and secure form of communication. Signal is primarily known for its mobile app, but there is also a desktop application based on Electron. The desktop app has a very annoying, long-standing issue which has already been reported on GitHub in 2018: Whenever a new application update is available, the app shows a message box prompting the user to restart Signal. Unfortunately - at least on macOS - Electron message boxes un-minimize the whole application window and show the message box on-top of the application.

This week, I changed my server OS from Debian to CentOS 7. Since I don’t appreciate having all those Ruby dependencies on my clients, I changed my static site generator to Hugo. I intend to bring back most of my old posts in the next few days.
