Let’s brainstorm a sustainable future together. Imagine: We are in the year 2050 and we’re opening the Museum of the Fossilized Internet, which commemorates two decades of a sustainable internet. …

Linux Foundation Executive Director Jim Zemlin recently spoke at Cloud Native + Open Source Virtual Summit China 2020. We’d now like to republish his opening comments and a guide on how to get involved with the TARS project, the open source microservices framework.

There's a saying about the cloud, and it goes something like this: The cloud is just somebody else's computer. While the cloud is actually more complex than that (it's a lot of computers), there's a lot of truth to the sentiment. When you move to the cloud, you're moving data and services and computing power to an entity you don't own or fully control. On the one hand, this frees you from having to perform administrative tasks you don't want to do, but, on the other hand, it could mean you no longer control your own computer. read more

I am mostly a self-taught programmer. When I was growing up in the late 1970s, our elementary school had a small resource room with an Apple II computer. My brother and I fell into a group of friends that liked computers, and we all helped each other learn the system. read more

In this tutorial, we will show you how to install Tiki Wiki CMS Groupware on Ubuntu 20.04 with Apache web server, MySQL Server, and PHP 7.4. Also, we will secure the Tiki Wiki CMS Groupware with SSL Letsencrypt.

The act of breaking something down in order to teach it to others can be a great way to reacquaint yourself with some old concepts and, in many cases, gain new insights. read more

To a veteran user of other distributions, Fedora can be a challenge. If you are making the transition from another distribution, here are a few observations and tips to get you started.

By default, pods accept traffic from any source. A network policy helps to specify how a group of pods can communicate with each other and other network endpoints.

Today, Firefox is introducing Enhanced Tracking Protection (ETP) 2.0, our next step in continuing to provide a safe and private experience for our users. ETP 2.0 protects you from an …

Data cannot be stored in the pod, when the pod is deleted or is terminated the data within it does not stay on the system. To provide long-term and temporary storage to Pods in the cluster, Kubernetes provides different types of storage mechanisms.

Facebook's man told: 'OK, now you are just trolling us'. Linux devs have dismissed a proposed patch to the kernel that would only work with a Nvidia driver, motivating a second patch that will prevent disguised use of proprietary code in GPL modules.…

Unfortunately, thanks to the coronavirus pandemic, it's harder than ever to take the tests you need to get or keep a certification. Red Hat, the Linux and cloud power, has an answer. Red Hat is extending your soon to expire certifications and has launched a new online certification testing program for its top four certifications.

Crash dump, memory dump, core dump, system dump … all produce the same outcome: a file containing the state of an application's memory at a specific time—usually when the application crashes. Knowing how to deal with these files can help you find the root cause(s) of a failure. Even if you are not a developer, dump files created on your system can be very helpful (as well as approachable) in understanding software. This is a hands-on article, and can you follow along with the example by cloning the sample application repository with: read more

Apache Solr is a scalable, reliable, and fault-tolerant NoSQL search tool written in Java and released under an OpenSource license. In this tutorial, we will show you how to install Apache Solr 8.6 on Ubuntu 20.04.

As you navigate the world of IT and technology, there are some terms you come across repeatedly. Some of them are hard to quantify and may take on different meanings as time goes on. "DevOps" is an example of a word that seems (to me) to change depending on the person using it; the original DevOps pioneers might not even recognize what we call DevOps today. read more

Most POSIX systems come with GNU bc, an arbitrary precision numeric processing language. Its syntax is similar to C, but it also supports interactive execution of statements and processing data from standard in (stdin). For that reason, it's often the answer to the question, "How do I do math in the Linux shell?" This style of response is common online: read more

The meteoric rise of containerization and microservices has been necessary to meet the growing demand for applications, but getting it right means overcoming some critical network orchestration challenges. Out of the complexities that developers of cloud-native applications face, strategically utilizing Kubernetes ingress controllers is among the most difficult components to understand—and among the most important.

Toolboxes started life often described as disposable containers – and that is still one of their major uses: install stuff, then try it out in the relative safety of a container, and lastly, cleanly dispose of it. If you have ever spent time setting up a toolbox container and would like to back it up, this article is for you.

Lots of love for AMD and POWER 10 and a hint of some Google's operational code making it into future releases Linus Torvalds has released a new version of the Linux kernel.…
