When GoldenDict enable scan popup functionality, if you want GoldenDict to show popup window, you need to select word by mouse and at same time press ALT or CTRL key. You can't show popup window only by mouse when needed. Add a function, when a word was selected by mouse, nearby the word there will be a small flag, when you move mouse on the flag, popup window appears.

For Relax-and-Recover (abbr. ReaR, RPM package rear) I like to implement a new kind of "backup" method:

Make openSUSE the first distribution to support LetsEncrypt/ACME natively, in order to provide easy TLS encryption for all services. openSUSE users should be able to 1. Request certificates for associated host names and keep them up-to-date.

https://software.opensuse.org/ is aging. Richard made a proposal using Jekyll to statically generate a new layout: https://software.opensuse.org/newsite/, code at https://github.com/sysrich/new-software.o.o

MALLOC_CHECK_ and MALLOC_PERTURB_ variables are environmental variables which help identify problems with Glibc's malloc() allocations. I intend to set them "globally" for every process via /etc/environment file and see, if test suites behave in usual way, identify problems.

Mojolicious is a web development toolkit and framework built around an event loop. That has many performance and scalability advantages, but can also make debugging slow code a bit of a challenge. Especially in big projects like openQA, where Devel::NYTProf can be a bit tricky to use, it would be nice to have more built-in diagnostics tools at the event reactor level. Mojo::UserAgent already has very good diagnostics features with MOJO_USERAGENT_DEBUG, and we should be able to do something similar for Mojo::IOLoop.

For far too long openQA instances are crippled by insufficient I/O throughput when under heavy load. This results in incomplete and aborted tests prolonging new snapshots testing and also adding confusion into the release process. OpenQA itself doesn't require any exact technology for its remote workers, but so far we relied on NFS. This was fine for few workers, now with 50+ of them this stopped to be a viable route however. There are some custom made mitigations like rsyncing tests, assets and needles before the actual test job run, but this feels like reinventing the wheel to me.

Fedora 25 has enabled Wayland by default for GNOME. Tumbleweed ships with Wayland too, but how far can we go in removing X11 components and get a X11 server free system, while keeping X11 applications support.

In the spirit of learning more python and practicing I will be creating a script to automate the work report emails that we send every week. This will not be a simple cron job because I have to catch corner cases of vacation etc. The next step is filling the workreport automatically by using the various API's that we can use (Bugzilla, osc qam plugin). The purpose is mainly to learn a bit more python.

You know Tetris, right? You know Telegram, don't you?

Control you openQA instance from an Amazon Echo!

How cool is that?

In openQA we support various backends which are able to 'host' tests. 'svirt' - one of those backends - is so generic that it allows to conned to a virtualization host via SSH a perform shell commands directly. As VirtualBox has decent command line interface (especially VBoxManage command) it shouldn't be that hard to support VirtualBox in openQA's os-autoinst via svirt backend.

By default, let's encrypt allows to get domain for server where you resolve an HTTP challenge. This is sometime not possible to setup (because the server you want your SSL certificate isn't running a HTTP server). Such example is my Synology NAS, where I don't want to have a Internet facing HTTP server, just to get a SSL certificate.

The Mojolicious web development toolkit is currently limited to using TCP/IP sockets for its HTTP/WebSocket client and server. For most web services that's more than enough, but for containerized applications and IPC, UNIX domain sockets could provide significantly better performance and security. Use cases would be for example faster communication between Mojolicious application servers and NGINX reverse proxies, or a WebSocket alternative to the D-BUS message bus currently being used by openQA.

CVRF is a standard where security advisories are encoded in a XML format. We are currently not generating such a format, but it seems to be getting more attention.

Take time this week to take care of the packages I maintain at Debian; open bugs, fix bugs, new upstream versions, enable testsuites in autopkgtest.
