Welcome Language Server Protocol
I’ve put a lot of effort to get YouCompleteMe and rtags configured and running: deployed compactly, updated automatically, adapted to vim, managed. And they served well until I found a better solution: language server protocol (LSP). It turns out to be as robust as simple to configure nowadays.

It turns out that tracking tweaks to the system, Arch Linux in my case, is a common concern. And it has already been solved by aconfmgr. This is a shell script, which calculates what has changed in the system: installed or removed packages; added, removed or changed files.

Building packages for Raspberry Pi using qemu-user
When I first packaged Kerberos.io for Arch Linux ARM, I merely adapted binaries built for Raspbian (see the kerberosio-alarm). It worked for a while until I upgraded to the version 2.4.0 as the machinery service started to crash. Apparently, due to lost ABI compatibility. So it’s time to build the application from the source code. Building on Raspberry PI is impractical due to limited resources, and setting up cross-compilation tools requires a great deal of accuracy. Luckily, I encountered a quick workaround: use qemu-user to allow running native compiler on an x86_64 machine (see the original post).

KVM for desktop virtualization retried
A year ago I concluded that VirtualBox would be the best choice for desktop virtualization. I ran Windows 7 back then and wasn’t able to get MSYS2 terminal emulator displayed lively. And now I was to install Windows 10, so took a chance to reevaluate KVM in pursuit for better performance. This time I started with libvirt and virt-manager.
