Red Hat and Fedora: syslog-ng, Ansible, Libinput and Fedora Community

• syslog-ng in two words at One Identity UNITE: reduce and simplify

  UNITE is the partner and user conference of One Identity, the company behind syslog-ng. This time the conference took place in Phoenix, Arizona where I talked to a number of American business customers and partners about syslog-ng. They were really enthusiastic about syslog-ng and emphasized two major reasons why they use syslog-ng or plan to introduce it to their infrastructure: syslog-ng allows them to reduce the log data volume and greatly simplify their infrastructure by introducing a separate log management layer. [...] When you collect log messages to a central location using syslog-ng, you can archive all of the messages there. If you add a new log analysis application to your infrastructure, you can just point syslog-ng at it and forward the necessary subset of log data there. Life at both security and operations in your environment becomes easier, as there is only a single software to check for security problems and distribute on your systems instead of many.

• Ansible vs Terraform vs Juju: Fight or cooperation?

  Ansible vs Terraform vs Juju vs Chef vs SaltStack vs Puppet vs CloudFormation – there are so many tools available out there. What are these tools? Do I need all of them? Are they fighting with each other or cooperating? The answer is not really straightforward. It usually depends on your needs and the particular use case. While some of these tools (Ansible, Chef, StaltStack, Puppet) are pure configuration management solutions, the others (Juju, Terraform, CloudFormation) focus more on services orchestration. For the purpose of this blog, we’re going to focus on Ansible vs Terraform vs Juju comparison – the three major players which have dominated the market. [...] Contrary to both Ansible and Terraform, Juju is an application modelling tool, developed and maintained by Canonical. You can use it to model and automate deployments of even very complex environments consisting of various interconnected applications. Examples of such environments include OpenStack, Kubernetes or Ceph clusters. Apart from the initial deployment, you can also use Juju to orchestrate deployed services too. Thanks to Juju you can backup, upgrade or scale-out your applications as easily as executing a single command. Like Terraform, Juju uses a declarative approach, but it brings it beyond the providers up to the applications layer. You can not only declare a number of machines to be deployed or number of application units, but also configuration options for deployed applications, relations between them, etc. Juju takes care of the rest of the job. This allows you to focus on shaping your application instead of struggling with the exact routines and recipes for deploying them. Forget the “How?” and focus on the “What?”.

• libinput's bus factor is 1

  Let's arbitrarily pick the 1.9.0 release (roughly 2 years ago) and look at the numbers: of the ~1200 commits since 1.9.0, just under 990 were done by me. In those 2 years we had 76 contributors in total, but only 24 of which have more than one commit and only 6 contributors have more than 5 commits. The numbers don't really change much even if we go all the way back to 1.0.0 in 2015. These numbers do not include the non-development work: release maintenance for new releases and point releases, reviewing CI failures [1], writing documentation (including the stuff on this blog), testing and bug triage. Right now, this is effectively all done by one person. This is... less than ideal. At this point libinput is more-or-less the only input stack we have [2] and all major distributions rely on it. It drives mice, touchpads, tablets, keyboards, touchscreens, trackballs, etc. so basically everything except joysticks.

• Fabiano Fidêncio: Libosinfo (Part I)

  Libosinfo is the operating system information database. As a project, it consists of three different parts, with the goal to provide a single place containing all the required information about an operating system in order to provision and manage it in a virtualized environment.

• Τι κάνεις FOSSCOMM 2019

  When the students visited our Fedora booth, they were excited to take some Fedora gifts, especially the tattoo sticker. I was asking how many of them used Fedora, and most of them were using Ubuntu, Linux Mint, Kali Linux and Elementary OS. It was an opportunity to share the Fedora 30 edition and give the beginner’s guide that the Fedora community wrote in a little book. Most of them enjoyed taking photos with the Linux frame I did in Edinburgh... [...] I was planning to teach the use of the GTK library with C, Python, and Vala. However, because of the time and the preference of the attendees, we only worked with C. The workshop was supported by Alex Angelo who also traduced some of my expressions in Greek. I was flexible in using different Operating Systems such as Linux Mint, Ubuntu, Kubuntu among other distros. There were only two users that used Fedora. Almost half of the audience did not bring a laptop, and then I grouped in groups to work together. I enjoyed to see young students eager to learn, they took their own notes, and asked questions. You might see the video of the workshop that was recorded by the organizers.

• Extending the Minimization objective

  Earlier this summer, the Fedora Council approved the first phase of the Minimization objective. Minimization looks at package dependencies and tries to minimize the footprint for a variety of use cases. The first phase resulted in the development of a feedback pipeline, a better understanding of the problem space, and some initial ideas for policy improvements.
