Red Hat: EPEL8, vDPA and Apache Kafka on OpenShift

Filed under
Red Hat
  • EPEL8 packages

    With the opening up of EPEL8, there’s a lot of folks looking and seeing packages they formerly used in EPEL6/7 not being available and wondering why. The reason is simple: EPEL is not a fixed exact list of packages, it’s a framework that allows interested parties to build and provide the packages they are interested in providing to the community.

    This means for a package to be in EPEL8, it requires a maintainer to step forward and explicitly ask “I’d like to maintain this in EPEL8” and then build, test and do all the other things needed to provide that package.

    The reason for this is simple: We want a high quality, maintained collection of packages. Simply building things once and never again doesn’t allow for someone fixing bugs, updating the package or adjusting it for other changes. We need a active maintainer there willing and able to do the work.

  • vDPA hands on: The proof is in the pudding

    In this post, we will set up vDPA using its DPDK framework. Since vDPA compatible HW cards are in the process of being commonly available on the market, we will work around the HW constraint by using a paravirtualized Virtio-net device in a guest as if it was a full Virtio HW offload NIC.

  • Open Banking with Microservices Architectures and Apache Kafka on OpenShift

    Last month, at OpenShift Commons Gathering Milan, Paolo Gigante and Pierluigi Sforza of Poste Italiane, showed the audience how they built a microservices based banking architecture using Apache Kafka and OpenShift. Their slides are available here. For more great in-person events like this, register for the next Commons Gathering near you! San Francisco is coming up before the end of the month, and will focus on AI/ML.

  • dnsZoneEntry: field should be removed when DD is retired

    When Debian Developer had retired, actual DNS entry is removed, but dnsZoneEntry: field is kept on LDAP (db.debian.org) So you can not reuse *.debian.net if retired Debian Developer owns your prefered subdomain already.

  • Canonical at OSM Hackfest MR#9

    The 12th OSM Hackfest, or OSM mid-release NINE (MR#9) Hackfest, is one for the books and Canonical happily shared the presenter floor with the rest of the Open Source MANO (OSM) community. The event spanned the whole week from September 7th to 11th, with Wednesday September 9th afternoon being used for the OSM Ecosystem day. As per the last two hackfests, the remote format allowed participation of hundreds of enthusiasts. During the preparation of the hackfest, it was agreed to keep the same theme as the last one, so participants were able to use OSM to manage and orchestrate workloads in an end-to-end open source mobile network solution with the Facebook Connectivity project; Magma. [...] David Garcia, the N2VC MDL, had multiple sessions during day 2; an introduction to OSM primitives, Juju relations and a 3 hour workshop on OSM orchestration of VNFs. OSM uses Juju as a core component and leverages operators to drive lifecycle management, workload configuration, daily operations and integration functions. Juju is a universal operator lifecycle manager (OLM) that exposes events to the operators and enables users to deploy simple to complex models of applications declaring business intent instead of dealing with piles of configuration scripts. [...] The Ecosystem Day, an integral part of every hackfest, is for the community to learn about vendor-oriented solutions and projects. Among others, we had a demo of 5G Core network automation by OSM from Ulak Communications, we learned about vBNG orchestration using Juju by Benu networks and subscription and notification support in OSM by Tata ELXSI. We also presented a session on Charmed OSM, Canonical’s carrier-grade, hardened OSM distribution. Charmed OSM allows operators, GSIs and NEPs to move faster with NFV transformation through open-source technology and partner programmes.

Initial Fedora 32 vs. Fedora 33 Beta Benchmarks Point To Slightly Higher Performance

In addition to Fedora Workstation 33 switching to Btrfs, there are a number of key components updated in Fedora 33 as well as finally enabling link-time optimizations (LTO) for package builds that make this next Fedora Linux installment quite interesting from a performance perspective. Here are some initial benchmarks of Fedora Workstation 32 against the Fedora Workstation 33 Beta on an Intel Core i9 10900K system. Given the Fedora 33 beta release, here are our initial benchmarks of Fedora 33 that is due for its official release in late October. Over the past few days I've been testing the test compose of Fedora 33 Beta with all updates applied -- it's been quite a nice experience. There hasn't been any show-stopping bugs and all-around running nicely. Read more

Second Beta out for Krita 4.4.0

Today, we’re releasing Krita 4.4.0 beta 2: we found a number of regressions and release blocking bugs. This beta has Android builds too, since we fixed many issues with accessing files on Android: however, because we now add translations the APK files are too big for the Play Store, and you will have to download them from download.kde.org Read more
