It’s been a few years now since I switched to Wayland. I use Sway, a compositor based on wlroots, and apart from the sporadic broken Wayland application (easy fix: force XWayland) and Java application (easy fix: set _JAVA_AWT_WM_NONREPARENTING=1), it’s mostly been great times. I have also been a long time user of UK International Keyboard, and that is the layout I know by heart and use on all physical keyboards. This layout builds upon the standard UK keyboard to enable you to type ṽårìóǘş kïņḑş õf åçĉëñţş äņḑ şẙḿbôĺş not found on the keyboard itself...

Docker is a container engine for the Linux operating system. It leverages two Linux kernel functionalities, chroot jails (or, nowadays, the pivot_root system call, but the details don’t really matter here) and namespaces, to create containers, or isolated environments where you can run processes separately from your host system. This has roughly the same advantages of virtualization: isolation (not), portability, separation of concerns, reproducibility. These are all good things for a lot of applications, including CI, orchestration, resilient setups, etc...

In the previous installment of the series, we analyzed the problem of near-istantaneous Internet connection failover without breaking existing connections for live video streaming. The solution we devised consists in setting up L2 GRE tunnels to a fixed gateway with a very reliable internet connection (think a dedicated machine in a datacenter), and using the Linux Bonding Driver’s link monitoring functionality to manage the failover for us. Now we are going to try and make it work...

Last week, a friend of mine posed the interesting problem he was facing at the company he’s working at of streaming video reliably from multiple commodity Internet connections. Since this is my kind of thing, I decided to give it a go. After discussing the problem a bit, we came up with the following requirements: It should be implemented at the network level, to work with any streaming software and/or device It should provide near-instantaneous (or even no-interruption) failover to allow for seamless live streaming It should be portable (i...
