How to set up DevPI, a PyPI-compatible Python development server

Friday 13th of July 2018 12:41:19 PM
The first time I used DevPI, I was getting ready for a camping trip with my wife and kids. By "getting ready" I do not mean practicing my s'mores-making skills. I mean that I knew my kids would be entertained by camp staff some of the time, and I planned to fix a few bugs in the Twisted package. I also knew I would not have internet on the campgrounds, so I needed to be able to develop without connecting to the internet.read more

GameMode 1.2 adds configuration options about the default and desired governors, now supports soft real-time scheduling on kernels with SCHED_ISO support and will then use renice to boost games to a higher priority, the GameMode service is now D-Bus activated than needing to be explicitly enabled by systemd, and the GameMode libraries are now properly versioned.

Jonathan Dieter: Small file performance on distributed filesystems - Round 2

Last year, I ran some benchmarks on the GlusterFS, CephFS and LizardFS distributed filesystems, with some interesting results. I had a request to redo the test after a LizardFS RC was released with a FUSE3 client, since it is supposed to give better small file performance. I did have a request last time to include RozoFS, but, after a brief glance at the documentation, it looks like it requires a minimum of four servers, and I only had three available. I also looked at OrangeFS (originally PVFS2), but it doesn’t seem to provide replication, and, in preliminary testing, it was over ten times slower than the alternatives. NFS was tested and its results are included as a baseline. I once again used compilebench, which was designed to emulate real-life disk usage by creating a kernel tree, reading all the files in the tree, simulating a compile of the tree, running make clean, and finally deleting the tree. The test was much the same as last time, but with one important difference. Last time, the clients were running on the same machines that were running the servers. LizardFS benefited hugely from this as it has a “prefer local chunkserver” feature that will skip the network completely if there’s a copy on the local server. This time around, the clients were run on completely separate machines from the servers, which removed that advantage for LizardFS, but which I believe is a better reflection on how distributed filesystems are generally used. I would like to quickly note that there was very little speed difference between LizardFS’s FUSE2 and FUSE3 clients. The numbers included are from the FUSE3 client, but they only differed by a few percentage points from the FUSE2 client. Read more

GNOME 3.30 Desktop Environment to Enter Beta on August 1, GNOME 3.29.4 Is Out

With a two-day delay, the GNOME Project through Javier Jardón announced today the release of the fourth and last development snapshot of the GNOME 3.30 desktop environment before it enters beta testing next month, GNOME 3.29.4, which continues to add improvements to various of GNOME's core components and applications. However, due to the summer vacation and the GUADEC conference, GNOME 3.29.4 isn't a major snapshot as many would have expected. It only adds some minor changes and bug fixes to a handful of components, including GNOME Shell, Mutter, Evolution, GNOME Photos, GNOME Builder, GNOME Online Accounts, Polari, Bijiben, Evince, Epiphany, Baobab, GNOME Control Center, and File Roller.
