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 […]

With the latest release of CentOS-7, we have added several new Alternative Architecture (AltArch) releases in addition to our standard x86_64 (x86 {Intel/AMD} 64-bit) architecture. Architectures (aka arches) in Linux distributions refer to the type of CPU on which the distribution runs.  In the case of our standard release, it runs on x86 64-bit CPUs […]

A Flashable Image for the Intel Edison The Intel Edison system-on-a-chip boards are pretty cool, a little compute module can plug into a number of different breakout boards. There's an Arduino-style board, and another form-factor featuring a bunch of stackable modules (GPIO, SD Card, OLED Screen etc.) Since the system is a dual-core Atom, we can […]

OpenStack is the current de facto standard for cloud computing platforms and is supported by all major Linux distributions. Coupled with its role as the base technology in the domains of NFV & SDN, it has become one of the hottest softwares for networking community. It is a combination of numerous components and services, which […]

The CentOS Project has been performing daily CI testing for quite a while using our t_functional test suite. This testing has solved numerous issues for us in the past, although since it was being run daily sometimes we needed to re-release problem packages after fixes were rolled in. We have gotten the run time down […]

Ten days ago I wrote an article here about an armv7hl test image for the Cubietruck 32-bit ARM board.  I have just uploaded a similar armv7hl image for the Raspberry Pi2. Both of these images are created with the RootFS Build Factory (a 2015 CentOS GSoC Project from Mandar Joshi sponsored by the CentOS Project). […]

FUDCon is the Fedora Users and Developers Conference, a major free software event held in various regions around the world, usually annually per region. This year the event in APAC is happening in Pune, India, from 26th to 28th June. I will be giving an introductory talk about the CentOS Cloud SIG (CCS) in the […]

As Jim Perrin pointed out in an earlier post here on, we have commenced an armv7 (actually, armv7hl) open build to try and produce CentOS-7 for arm32 boards like the Cubietruck, Raspberry Pi2, and ODROID-C1 (among others). We now have a minimal sdcard only image for the Cubietruck from our unsigned (and as yet […]

The rolling ISO media releases for CentOS 7 for May 2015 (1505) are now available. These rolling ISO media releases are basically just respins of the install media at release time with all bugfix, enhancement, and security updates since release rolled in.  The updated ISOs for 1505 are based on all updates in the CentOS […]

The CentOS Project is now providing a signed copy of the repodata metadata file (repomd.xml.asc) for our Updates Repository for both CentOS-6 and CentOS-7.  To use this feature, you would edit the file /etc/yum.repos.d/ CentOS-Base.repo and locate the [updates] section, the default looks like this: #released updates [updates] name=CentOS-$releasever - Updates mirrorlist=$releasever&arch=$basearch&repo=updates&infra=$infra #baseurl=$releasever/updates/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 […]
