Server: OpenSMTPD and Dovecot, Containers and Kubernetes

  • Setting up an email server in 2020 with OpenSMTPD and Dovecot

    So, you want to set up your own email server? In that case, welcome.

    There are many reasons to run a custom email server, ranging from privacy concerns about providers like Google, to just wanting to do it for fun and/or learning. Since you're here, I assume you've already found a reason.

    Beware: this is a messy topic, and the available documentation is even messier, so it could take a while before you get it to work properly. I've compiled this guide according to my experiences in an attempt to make this dark art more accessible, but your mileage may vary considerably. I hope you find it useful.

  • Docker's Compose specification is now an open standard

    Docker Compose, the system created by Docker to define multi-container applications, is now to be developed as an open standard. The Compose Specification, as the new standard is called, is meant to allow Compose-created apps to work on other multi-container definition systems on platforms such as Kubernetes and Amazon Elastic Container Service.

  • How Kubernetes saved my desktop application

    Recently, fellow Opensource.com scribe James Farrell wrote a wonderful article entitled How Ansible brought peace to my home. In addition to the great article, I really liked the title, one of those unexpected phrases that I’m sure brought a smile to many faces. I recently had a weird but positive experience of my own that begs a similar sort of unexpected label. I’ve been grappling with a difficult problem that arose when upgrading some server and networking infrastructure that broke a Java application I’ve been supporting since the early 2000s. Strangely enough, I found the solution in what appears to be a very informative and excellent article on Kubernetes, of all things.

Git version control system hits 15 year milestone

Happy birthday, Git. The open source distributed version control system was first released on April 7th 2005, and thus today marks its 15th anniversary - 15 years aiding software developers to collaborate on projects large and small no matter where on the globe they may be. Git began life when the Linux kernel team sought a highly performant, distributed and robust version control platform for developers worldwide. This is an important tool in the development pipeline, allowing new code from multiple developers to be pulled together with robust protections from corruption. Finding nothing suitable, Linus Torvalds wrote his own - after all, what else would Linus do? He began on April 3rd 2005 and released it on April 7th. Read more

AV Linux 2020.4.10 Released!

Shortly after the Christmas holidays some time opened up for me to work on an AV Linux update and as time went on the rumours about a new respiratory virus started to permeate the mainstream media and now here we are in the middle of a worldwide pandemic! So it is with mixed feelings but much gratitude I release the latest ISO of AV Linux 2020. I am very thankful for the multitudes of talented developers and collaborators from all over the world whose incredible work I get to present and share on this little DVD-sized serving platter, my compliments to the chefs!! It occured to me recently that with the exception of Ubuntu Studio and perhaps the CCRMA project AV Linux is the longest running Linux Audio Distribution out there, As with many DIY spare time projects there have been times of ebb and flow and even a few times when continuing seemed to be impossible but I have to say the odds were never great for a Canadian farmer to pull this off in the first place and it’s still here! Unlike older versions of AV Linux this LiveISO is not aiming to provide an everything-but-the-kitchen-sink experience, running Linux Distros live off thumbdrives is fun but in the real world nobody is going to spend a sustained amount of time using any Operating System to it’s full potential from a USB Key… what’s possible isn’t necessarily practical. The idea here is to focus on a fast, efficient and attractive base and complement it with strong front-running applications to showcase good performance and reliable software with an eye toward practicality and economy. Ardour and Mixbus32C are great included DAW examples but what makes AV Linux a good platform for Ardour also makes it a good platform for Qtractor, Reaper, Bitwig, Renoise, Waveform or whatever DAW you prefer. For those not experienced with Linux Audio the intention is to answer your questions before you know to ask them and provide most of the laborious ‘next steps’ that would be required if you were to start with a basic vanilla Linux Distribution and configure it for the best Audio performance.
