Use this script to find a Raspberry Pi on your network

Monday 8th of June 2020 07:02:00 AM

We've all been there. "I'm going to get this Raspberry Pi to try out. They look kinda cool." And then, like tribbles on an Enterprise, suddenly you have Kubernetes clusters and NFS servers and Tor proxies. Maybe even a hotel booking system!

A secure and private open source alternative to Alexa

Monday 8th of June 2020 07:00:00 AM

I grew up in rural towns all over Ontario, Canada. We weren't particularly well off, although, as a kid in the middle of nowhere, I wasn't really aware of our socioeconomic status. What I was aware of was this beige box called a computer that sat in my dad's office. Dad worked for the bank, and for his job, it was essential for him to have a computer. So while we never had the latest gaming console, we always had a computer.

Eliminate spam using SSL with an open source certification authority

Monday 8th of June 2020 07:00:00 AM

MailCleaner is a feature-rich, open source antispam solution. Its virtual appliances (VMs) available for distribution come out-of-the-box with self-signed certificates for both the web interface and the MTA services.

This requires you to supply your own valid, publicly trusted certificate. Using a Let's Encrypt certificate is a great way to accomplish that because it's free, safe, and automated.

5 ways to boost your Kubernetes knowledge

Sunday 7th of June 2020 07:02:00 AM

When the cloud was still in its formative years, developers discovered that it was convenient to write applications in small, atomic, minimal Linux images that shared resources with the server they ran on. Technically based on kernel namespaces, these small environment definitions came to be called containers. As containers proliferated, sysadmins quickly realized it was becoming essential to develop a tool that could help them manage not only containers but also the virtualized infrastructure underneath.

What are the pros and cons of virtual events?

Saturday 6th of June 2020 07:02:00 AM

The COVID-19 pandemic disturbed the work of event organizers everywhere. To slow the spread of this highly contagious virus, conferences that tend to host thousands in person faced a choice: Move entirely online, or cancel altogether. Many open source event organizers chose the latter, but not all of them.

3 charts that show how open source developers think

Saturday 6th of June 2020 07:01:00 AM

Each year, the team at Tidelift asks developers to update us on how they are managing their use of open source dependencies for application development. In June 2019, almost 400 professional software developers responded to our survey with input on "how they use open source software today, what holds them back, and what tools and strategies would help them use it even more effectively."

A beginner's guide to Kubernetes container orchestration

Friday 5th of June 2020 07:02:00 AM

Last fall, I took on a new role with a team that relies on Kubernetes (K8s) as part of its core infrastructure. While I have worked with a variety of container orchestrators in my time (e.g., Kubernetes, Apache Mesos, Amazon ECS), the job change sent me back to the basics. Here is my take on the fundamentals you should be familiar with if you're working with Kubernetes.

Provision Kubernetes NFS clients on a Raspberry Pi homelab

Friday 5th of June 2020 07:01:00 AM

Ephemeral containers are useful, but sometimes data needs to persist between containers or be shared among multiple containers. The solution is mounting external volumes inside the containers, and this is done in Kubernetes with persistent volumes. In large, public cloud deployments, Kubernetes has integrations with the cloud providers' block-storage backends, allowing developers to create claims for volumes to use with their deployments, and Kubernetes works with the cloud provider to create a volume and mount it in the developers' pods.

Reading about open source in French

Friday 5th of June 2020 07:00:00 AM

English speakers have so many wonderful open source resources that it's easy to forget that communications in English aren't accessible to everyone everywhere. Therefore, I've been looking for great open source resources in Spanish and French, so I can recommend them when the need arises.

Improve Linux system performance with noatime

Thursday 4th of June 2020 07:01:00 AM

Whenever I upgrade Linux on my home computer, I have a list of tasks I usually do. They've become habits over the years: I back up my files, wipe the system, reinstall from scratch, restore my files, then reinstall my favorite extra applications. I also make a few system tweaks. I've been making some of these tweaks for so long that I recently wondered if I still needed to do them.

Using AppImage for Linux package management

Thursday 4th of June 2020 07:00:00 AM

A big part of administrating Linux machines—especially remote machines—is managing and installing software. When something goes wrong with a local application or when something on the filesystem breaks and needs fixing, you're often going to want to push updates without having to travel many miles to sit down in front of a physical screen.

6 Best Free and Open Source Linux Anti-Spam Tools

Email is one of the primary communication channels among users. The Radicati Group is an organization which publishes quantitative and qualitative research on business and consumer usage for email, instant messaging, social networking, wireless email, and unified communications. Their research estimates that the total worldwide emails in 2020 is 306 billion. The cost of spam is frightening, estimated to be approximately $50 billion each year. The tide of the daily spam is a continual thorn in the side for both providers and users. Spam is a waste of valuable network bandwidth, disk space and takes up users’ valuable time to declutter their mailboxes. Many spam messages contain URLs to a dubious website or websites, peddling fake pharmaceutical products, replicas, enhancers, or gambling. Alternatively, the URLs may be phishing attacks, for example taking an unwitting victim to a site which seeks to steal private information such as bank account login data. Read more
