For over 10 years, VMware was accused of illegally using Linux code in its VMware ESX bare-metal virtual machine hypervisor. After a German court dismissed the case, the Linux programmer behind the lawsuit has called it a day.

In preparation for taking the Linux Professional Institute Certification exam LPI-302 for systems administrators, learn how to set up and store passwords, integrate Samba with LDAP, and use ACLs to protect your Linux installation.

Linux Journal's very first issue featured an interview between LJ's first Publisher, Robert Young (who went on to co-found Red Hat among other things), and Linus Torvalds (author of the Linux kernel). After 25 years, we thought it'd be interesting to get the two of them together again. You can read that first interview from 1994 here.

Samba uses Trivial Database files to store both persistent and temporary data as part of its job integrating file and print sharing between Linux and Windows. In preparation for the Linux Professional Institute Certification exam LPI-302, learn all about the Samba Trivial Database (TDB) format that Samba uses to store information, how to look inside TDB files, and how to back them up.

Git is one of those rare applications that has managed to encapsulate so much of modern computing into one program that it ends up serving as the computational engine for many other applications. While it's best-known for tracking source code changes in software development, it has many other uses that can make your life easier and more organized. In this series leading up to Git's 14th anniversary on April 7, we'll share seven little-known ways to use Git. Today, we'll look at using Git to keep track of your calendar. read more

Video: SUSE will soon be the largest independent Linux company.

One frequent complaint about Python performance is the global interpreter lock (GIL). Because of GIL, only one thread can execute Python byte code at a time. As a consequence, using threads does not speed up computation—even on modern, multi-core machines. read more

Educators in elementary computer science face a lack of adaptable curricula. Calls for more modifiable, non-rigid curricula are therefore enticing—assuming that such curricula could benefit teachers by increasing their ability to mold resources for individual classrooms and, ultimately, produce better teaching experiences and learning outcomes. read more

Writing and receiving email is a big part of everyone’s daily routine and choosing an email client is usually a major decision. The Fedora OS provides a large choice of email clients and among these are text-based email applications. Mutt Mutt is probably one of the most popular text-based email clients. It supports all the […]

Irrespective of the programming language you use, as you start coding more and more, you get to learn concepts that make your code crisp and easy to read/understand. There are several such concepts in the C as well. One of them is 'recursive functions,' which we'll be discussing here in this article.

Many software projects depend on modules that are run as separate open source projects. When one of those modules loses support (as is inevitable), the community around the main project must determine how to proceed. read more

Most magazines have the life expectancy of a house plant.... Our first publisher was Bob Young, who quickly left to leverage his on-the-job learnings into a Linux startup he called Red Hat. When I first met Bob, years later, I told him Phil said, "I taught Bob how to spell Linux." To my surprise, Bob replied, "That's true!"

In computing, a filesystem controls how data is stored and retrieved and helps organize the files on the storage media. Without a filesystem, information in storage would be one large block of data, and you couldn't tell where one piece of information stopped and the next began. A filesystem helps manage all of this by providing names to files that store data and maintaining a table of files and directories—along with their start/end location, total size, etc.—on disks within the filesystem. read more

We’ll be installing LAM on the same server we installed OpenLDAP, so make sure you’ve walked through the process from the previous article. With that taken care of, let’s get LAM up and running, so you can more easily add users to your LDAP directory tree.

About a year ago, I wrote about measuring air quality using a Raspberry Pi and a cheap sensor. We've been using this project in our school and privately for a few years now. However, it has one disadvantage: It is not portable because it depends on a WLAN network or a wired network connection to work. You can't even access the sensor's measurements if the Raspberry Pi and the smartphone or computer are not on the same network.

One binary to rule them all. Mozilla this week announced a project called WASI (WebAssembly System Interface) to standardize how WebAssembly code interacts with operating systems. If the project succeeds, it will do what Oracle's Java Virtual Machine does, but better and more broadly.…

WhiteSource review of programming language security errors reveal which languages have the most security holes. The winner? C. But that's only the start of the story.

In this week's edition of our open source news roundup, we take a look at a 3D-print system for optical cardiography, Carnegie Mellon's Digital Learning Tools, Apache Software Foundation's 20th anniversary, and more.

I spend a lot of time doing research for my books and Opensource.com articles. Sometimes this leads me to discover bugs in the software I use, including Fedora and the Linux kernel. As a long-time Linux user and sysadmin, I have benefited greatly from GNU/Linux, and I like to give back. I am not a C language programmer, so I don't create fixes and submit them with bug reports, as some people do. But a way I can return some value to the Linux community is by reporting bugs. read more
