Benchmarks Of Btrfs RAID On Four Samsung 970 EVO NVMe SSDs

With the MSI MEG X399 CREATION that we received as part of the launch package for the Threadripper 2950X and Threadripper 2990WX it includes the XPANDER-AERO that provides 4-way M.2 NVMe SSD slots on a PCI Express x16 card. The XPANDER-AERO is actively cooled and could be passed off as a small form factor graphics card upon a very cursory examination. With this card I've been running tests on four Samsung 970 EVO NVMe SSDs in RAID to offer stellar Linux I/O performance. Here are some initial benchmarks using Btrfs.

KDE: Kate and Akademy 2018

• Kate gains Support for Inline Notes

  Thanks to Michal Srb and Sven Brauch for pioneering the work an a new KTextEditor interface that allows applications like Kate, KDevelop, etc. to display inline notes in a text document.

• Akademy 2018 was great!

  So Akademy 2018 has finished and it was a very impressive event. It happened in Vienna, Austria and it was my first opportunity to join in a KDE event, to travel to another country and to meet people from the community! I couldn’t participate during the first day of the event (August 11th) because my flight delayed a little bit and I only arrived in Vienna by night. So in the first day I only had the opportunity to join the people for a drink and prove some Wiener schnitzel and food from Austria.

• Akademy 2018 wrap-up

  As I am writing this, I am sitting in a train home from Akademy 2018, KDE’s annual developer conference, which took place in Vienna this year. Akademy always is a great mix of some talks, some socializing with people you otherwise only communicate with through mailing lists or IRC, and some hacking, and this year’s conference was no exception to this. In this post, I will detail some of the technical progress we made and some of the things we discussed.

• And we’re almost home…

  I went to Akademy feeling that the relationship been Krita and KDE is kinda difficult. Krita is part of KDE, but at the same time, Krita is getting really big. We’re using up quite a chunk of bandwidth, after plasmashell, we’re the project with the second-most bugs reported per year, and still people working on Krita don’t have much of a tie to KDE, and people working on KDE seldom have much of an idea what’s going on in Krita — other than nodding and telliing me Krita is one of KDE’s flagship projects. Sure it is, and I got very much reassured that we’re not using too large a chunk of KDE’s resources, and could even use more. I’m not sure how to “fix” this, if a fix is possible. If we’d have our Krita sprint during Akademy, I’m sure that would help — but it would also be a pretty improductive sprint for Krita.
