• Porting guide from Qt 1.0 to 5.11

• Thunderbolt Networking on Linux

  Thunderbolt allows for peer-to-peer network connections by connecting two computers directly via a thunderbolt cable. Mika from Intel added support for this to the 4.15 kernel.

• What’s new in openSUSE Leap 15 – part 1

  openSUSE Leap 15 will be released on the 25th of May 2018! A new openSUSE release is always an exciting event. This means that I get to play with all kinds of new and improved software packages. I am aware that I can simply install openSUSE Tumbleweed and have a new release 4 or 5 times a week. But when using openSUSE Tumbleweed some time ago, I noticed that I was installing Gigabytes of new software packages multiple times per week. The reason for that is that I have the complete opposite of a minimum install. I always install a lot of applications to play / experiment with (including a lot of open source games). I am using openSUSE since 2009 and it covers all of my needs and then some. I am already happy with the available software, so there is no real reason for me to move with the speed of a rolling release. Therefore I prefer to move with the slower pace of the Leap releases.

While it's not out yet, their release notes were recently updated for providing an overview of what's coming as part of this next major update.
