Get a /56 from Spectrum using wide-dhcpv6

After writing my last post on my IPv6 woes with my Pixel 3, some readers asked how I’m handling IPv6 on my router lately. I wrote about this previously when Spectrum was Time Warner Cable and I was using Mikrotik network devices. There is a good post from 2015 on the blog and it still works today: Time Warner Road Runner, Linux, and large IPv6 subnets I am still using that same setup today, but some readers found it difficult to find the post since Time Warner Cable has renamed to Spectrum.

Pixel 3 Wi-Fi drops constantly

We have two Google Pixel phones in our house: a Pixel 2 and a Pixel 3. Both of them drop off our home wireless network regularly. It causes lots of problems with various applications on the phones, especially casting video via Chromecast. At the time when I first noticed the drops, I was using a pair of wireless access points (APs) from Engenius: EAP600 EAP1200H Also, here’s what I knew at the time:

Stop audio pops on Intel HD Audio

I recently picked up a Dell Optiplex 7060 and I’m using it as my main workstation now. The Fedora installation was easy, but I noticed a variety of “pop” or clicking sounds when audio played, especially terminal bells. If everything was quiet and I triggered a terminal bell, I would hear a loud pop just before the terminal bell sound. However, if I played music and then triggered a terminal bell, the pop was gone.

Automatic floating windows in i3

The i3 window manager is a fast window manager that helps you keep all of your applications in the right place. It automatically tiles windows and can manage those tiles across multiple virtual desktops. However, there are certain applications that I really prefer in a floating window. Floating windows do not get tiled and they can easily be dragged around with your mouse. They’re the type of windows you expect to see on other non-tiling desktops such as GNOME or KDE.

DevConf.CZ 2019 Recap

DevConf.CZ 2019 wrapped up last weekend and it was a great event packed with lots of knowledgeable speakers, an engaging hallway track, and delicious food. This was my first trip to any DevConf and it was my second trip to Brno. Lots of snow showed up on the second day and more snow arrived later in the week!

First talk of 2019 I co-presented a talk with one of my teammates, Nikolai, about some of the fun work we’ve been doing at Red Hat to improve the quality of the Linux kernel in an automated way.
