Long version: I recently stuck on connecting my Trakz Titanium Bluetooth headset in Manjaro Linux (kernel version 5.8.18-1). I saw it in the list of Bluetooth devices to connect, but nothing happened if I set the connection on. Needless to say that there was no option to choose a headset in the list of sound devices.
I had to spend some time reading docs, installing packages, and playing with conf files, and finally found the reason, so hopefully, this article saves you from this tedious journey.
I’m a big fan of dark themes for websites and apps. They make browsing more comfortable to my eyes, especially after a long day and during the night. Unfortunately, there are still lots of sites (including the most popular ones) that offer only the default «white background» style which makes using them eye-leaking.
Until today, I used the Stylus plugin for my browser which has a comprehensive library of themes that applies over the top of the default website style. It worked for me, although I still had to write my own styles for some unpopular sites, another issue was that styles from the community-developed library were often outdated.
Fortunately, developers of Chrome browser recently solved that issue for us, so that you can easily turn on (and off) the dark theme for most of the sites, also you don’t need any plugins anymore.
To enable dark themes:
Type chrome://flags/ URL in Chrome browser address bar
Search for #enable-force-dark (Force Dark Mode for Web Contents) setting and Enable it (you may play with different modes if you faced performance issues, but to me simple «Enabled» option works just fine).
That’s it! Open your favourite website on the browser and check it out.

There are recognized ‘brands’ of certification authorities that may you offer proof of your knowledge, for example ISTQB/BCS (former ISEB). They have many different levels and often employers may state they desire at least Foundation level certificate from job seekers.
Nonetheless, there are another provides, yet your local Software Testing Qualification Board or community may have different programms.
I have collected links to the most known certification authorities and local boards. Hope, this can be helpful someone.
I’ve got this issue recently when installed VirtualBox on my Manjaro Linux (this distro based on Arch Linux, so the solution would work there as well).
It seems that VirtualBox, while installing its virtual network adapters, had messed up the existing physical ones. That led to the situation when, once you reboot your machine, there is no network connection to the internet.
