CentOS Dojo at DevConf.us, August 16th in Boston

This year, DevConf.us will be held at Boston University, August 17th through 19th. We’ve secured some space on the day before – Thursday, August 16th – and will be holding a CentOS Dojo. Further details will appear on the event website as they are available. The call for papers is now open, and will close […]

FOSDEM 2018

Another FOSDEM is history. I wanted to take a moment to thank all of the people that helped out at the CentOS table at FOSDEM, as well as at the Dojo before FOSDEM. We had about 75 people in attendance at the Dojo on Friday, with 12 presentations from various speakers. Some of these presentations […]

SuperComputing17 Denver, #PoweredByCentOS

SC17, the largest SuperComputing event in the world, was held in Denver, Colorado, November 12 through 17th. I was lucky enough to attend the event as a representative of the CentOS community. While there, I spoke with dozens of organizations that use CentOS as part of their High Performance Computing (HPC) infrastructure. I also got […]

No! Don’t turn off SELinux!

One of the daily activities of the CentOS Community Lead is searching the Internet looking for new and interesting content about CentOS that we can share on the @CentOSProject Twitter account, or Facebook, Google +, or Reddit. There’s quite a bit of content out there, too, since CentOS is very popular. Unfortunately, some of the content […]

HPC Student Cluster Competition, Frankfurt, Germany

Last week, as I mentioned in my earlier post, I was in Frankfurt, Germany, for the ISC High Performance Computing conference. The thing that grabbed my attention, more than anything else, was the Student Cluster Competition.  11 teams from around the world – mostly from Universities – were competing to create the fastest (by a variety […]

Continuous integration tests for the CentOS Vagrant images

Since yesterday, we have production-ready automated tests for our Vagrant images on ci.centos.org, fully integrated with GitHub. We were only able to build and test scratch images manually until now, which was time consuming and had the disadvantage that, due to hardware limitations on my side, only the images for VirtualBox were actually tested. A […]

Badges Badges Badges: Reporting CICO Job Status across the Web

Testing your software project is important. Effectively communicating your test results to those that consume your project comes in a close second. Recently we enabled the Embeddable Build Status plugin in https://ci.centos.org which provides Pass/Fail images for the latest build of each job in CICO. These badges are perfect for inclusion in upstream webpages, and in Github README […]

CentOS 7 with GlusterFS on AArch64

Initially I meant for this to be a much more in-depth blog post about running GlusterFS on AArch64 hardware, but honestly it’s been ridiculously easyto get running. There isn’t much to say about running it that isn’t already covered in the GlusterFS quickstart guide. Even building GlusterFS on AArch64 was a snap; I simply pulled […]

Running CentOS Linux 7 on AArch64 hardware

The journey for rebuilding the latest release of CentOS Linux 7 on AArch64 hardware has certainly been an interesting one. After a few bug reports, a couple minor patches, and several iterations through the build system, we finally have a release for community testing and consumption, which we’ll have available for install early next week. There […]

CentOS Linux 7 and Arm

ARMv7 With the growing list of easily accessible ARM hardware like the RaspBerry Pi 2 and the ODROID-C1, several community efforts have sprouted, working out the details for getting CentOS-7 built and available for the new boards. One of our UK based community members has made the most progress so far, posting his build process […]

MATE on the Desktop

A number of people seem to not like the idea of gnome3 on the desktop for EL7, instead looking for the familiar gnome2 feel. I’ve taken a run at building MATE on the el7 beta and it looks pretty good overall. Over the next few days I’d like to sit down with some of the […]

NetworkManager and bridging

In previous iterations of NetworkManager, it was really only useful if you were dealing with wireless networks. Anything involving a bridge meant removing the device from NetworkManager, and manually configuring the network. A fair amount of work has been done to make NetworkManager more friendly to bridged devices, however it’s still far from perfect.   […]
