It seems everyone is rushing to get their software on the cloud. The rapid growth of cloud computing has empowered hyperscaler cloud providers to market various technologies to feed the growing demand. Hyperscalers are now providing full-stack capabilities to increase their footprint and further lock-in customers, making the cloud seem more like a threat than an open communal space.

A serious memory corruption vulnerability in polkit (formerly PolicyKit) has finally been discovered after 12+ years. This program is found in essentially all modern Linux distributions.

Brian Kernighan shares his inspiration and research behind the latest edition of his book, Understanding the Digital World.

Ansible is a simple and powerful open source automation tool that can streamline many of your IT infrastructure operations. You can automate simple tasks like installing packages, or complex workflows such as deploying a clustered solution with multiple nodes or patching your operating system with many steps.

I am not heartbroken (or maybe I am and I don’t want to tell you). But I would still like to show you a wonderful minimalistic open-source, note-taking application to keep journal entries. This handy little program is Jrnl and it lets you create, search and view journal entries right in the terminal.

One of the primary functions of computers is to parse data. Some data is easier to parse than other data, and voice input continues to be a work in progress. There have been many improvements in the area in recent years, though, and one of them is in the form of DeepSpeech, a project by Mozilla, the foundation that maintains the Firefox web browser. DeepSpeech is a voice-to-text command and library, making it useful for users who need to transform voice input into text and developers who want to provide voice input for their applications.

Want a good-paying programming job? By ZipRecruiter's count, the average annual pay for an open-source developer in the United States is $123,411. That's not bad. There's also a lot of demand for Linux and open-source pros. The Linux Foundation and edX, the leading massive open online course (MOOC) provider, reported in their 2021 Open Source Jobs Report that the pair found more demand for top open-source workers than ever.

Apache Solr or Solr is a free and open-source search platform based on the Apache Lucene library.

I like the Groovy programming language a lot. I like it because, in the end, I like Java, even though Java sometimes feels clumsy. And because I like Java so much, I don't find many other JVM languages especially attractive. Kotlin, Scala, and Clojure, for example, don't feel much like Java, pursuing their own perspectives on what makes a good programming language.

The Vi application is the default text editor on most Linux systems, so it's the primary interface you will use when you need to edit a configuration file. If you're used to a graphical text editor, such as Notepad++ or VS Code, Vi can be confusing at first.
