It happens all the time, to the largest of companies. An important certificate doesn't get renewed, and services become inaccessible. It happened to Microsoft Teams in early February 2020, awkwardly timed just after the launch of a major television campaign promoting it as a Slack competitor. Embarrassing as that may be, it's sure to happen to someone else in the future. read more

Over the past decade, solid-state drives (SSD) have brought about a new way of managing storage. SSDs have benefits like silent and cooler operation and a faster interface spec, compared to their elder spinning ancestors. Of course, new technology brings with it new methods of maintenance and management. SSDs have a feature called TRIM. This is essentially a method for reclaiming unused blocks on the device, which may have been previously written, but no longer contain valid data and therefore, can be returned to the general storage pool for reuse. read more

Byobu is a text-based window manager and terminal multiplexer. It's similar to GNU Screen but more modern and more intuitive. It also works on most Linux, BSD, and Mac distributions. Byobu allows you to maintain multiple terminal windows, connect via SSH (secure shell), disconnect, reconnect, and even let other people access it, all while keeping the session alive. read more

As part of my role as a senior product marketing manager at an enterprise software company with an open source development model, I publish a regular update about open source community, market, and industry trends for product marketers, managers, and other influencers. Here are five of my and their favorite articles from that update.

Orangescrum is an open-source and collaboration web application written by using CakePHP. It is simple and easy to use tools to manage projects, teams, documents, tasks, and communicate with the team on important issues.

RPM stands for "Redhat Package Manager" is a command-line package management tool for RHEL/CentOS based operating system. In this tutorial, we will show you how to use RPM package manager with some examples.

Any organization facing the prospect of change will confront an underlying tension between competing needs for standardization and innovation. Achieving the correct balance between these needs can be essential to an organization's success. Experiencing too much of either can lead to morale and productivity problems. Over-stressing standardization, for example, can have a stifling effect on the team's ability to innovate to solve new problems. Unfettered innovation, on the other hand, can lead to time lost due to duplicated or misdirected efforts. read more

Java comes with a core set of libraries, including those that define commonly used data types and related behavior, like String or Date; utilities to interact with the host operating system, such as System or File; and useful subsystems to manage security, deal with network communications, and create or parse XML. Given the richness of this core set of libraries, it's often easy to find the necessary bits and pieces to reduce the amount of code a programmer must write to solve a problem. read more

Recently, my husband was telling me about an upcoming job interview where he would have to run through some basic commands on a computer. He was anxious about the interview, but the best way for him to learn and remember things has always been to equate the thing he doesn't know to something very familiar to him. Because our conversation happened right after I was roaming the grocery store trying to decide what to cook that evening, it inspired me to write about kubectl and Helm commands by equating them to an ordinary trip to the grocer. read more

In what may prove to be the biggest migration from Windows to the Linux desktop, the South Korean government is looking into shifting from Windows 7 to a trio of Linux desktops.

I gave a talk about multi-architecture container images at LISA19 in October that included a lengthy live demo. Rather than writing out 30+ commands and risking typos, I decided to automate the demo with a shell script. read more

When you're running containers with Kubernetes, you often find that they pile up. This is by design. It's one of the advantages of containers: they're cheap to start whenever a new one is needed. You can use a front-end like OpenShift or OKD to manage pods and containers. Those make it easy to visualize what you have set up, and have a rich set of commands for quick interactions. read more

I met Brendan Becker working in a computer store in 1999. We both enjoyed building custom computers and installing Linux on them. Brendan was always involved in several technology projects at once, ranging from game coding to music composition. Fast-forwarding a few years from the days of computer stores, he went on to write pyDance, an open source implementation of multiple dancing games, and then became the CEO of music and gaming event MAGFest. Sometimes referred to as "Mr. read more

MPD, as the name implies, is a Music Playing Daemon. It can play music but, being a daemon, any piece of software can interface with it and play sounds, including some CLI clients. One of them is called ncmpcpp, which is an improvement over the pre-existing ncmpc tool. The name change doesn’t have much to […]

In my article about getting started with YaCy, I explained how to install and start using the YaCy peer-to-peer search engine. One of the most exciting things about YaCy, however, is the fact that it's a local client. Each user owns and operates a node in a globally distributed search engine infrastructure, which means each user is in full control of how they navigate and experience the World Wide Web. read more

There's a lot to be learned from open source projects. After all, managing hundreds of disparate, asynchronous commits and bugs doesn't happen by accident. Someone or something has to coordinate releases, and keep all the code and project roadmaps organized. It's a lot like life. You have lots of tasks demanding your attention, and you have to tend to each in turn. To ensure everything gets done before its deadline, you try to stay organized and focused.

Automation takes control of manual, laborious, and error-prone processes and replaces engineers performing manual tasks with computers running automation scripts. Everyone agrees that manual processes are a foe of a healthy DevOps mindset. Some argue that automation is not a good thing because it replaces hard-working engineers, while others realize that it boosts consistency, reliability, and efficiency, saves time, and (most importantly) enables engineers to work smart.

The kernel team is working on final integration for kernel 5.5. This version was just recently released, and will arrive soon in Fedora. This version has many security fixes included. As a result, the Fedora kernel and QA teams have organized a test week from Monday, February 10, 2020 through Monday, February 17, 2020. Refer […]

A long time ago, the internet was small enough to be indexed by a few people who gathered the names and locations of all websites and listed them each by topic on a page or in a printed book. As the World Wide Web network grew, the "web rings" convention developed, in which sites with a similar theme or topic or sensibility banded together to form a circular path to each member. A visitor to any site in the ring could click a button to proceed to the next or previous site in the ring to discover new sites relevant to their interest. read more
