If you're on the HWE stack, you'll get the Jammy kernel. Ubuntu 20.04 is nowhere near end of life, but 22.04 is starting to hit its stride.…

The use of Web Applications is growing amongst businesses, however, that also makes these businesses a target for Cyber Criminals to attack. If there are vulnerabilities within your Web Application, then that means there is a flaw that attackers may exploit to really wreak some havoc to an individual, small business, or even large corporations alike.

One of my favorite utilities on the Linux command-line, and block storage is one of my favorite features on Linode's platform, so in this article I get to combine both of these together - because what I'm going to be doing is show you how to use rsync to copy data from one server to another, in the form of a backup. What's really cool about this, is that this example will utilize block storage.

Want to easily give your old PC a new life? Here's how to do it with Google's Chrome OS Flex.

When I use the Linux command line, whether I'm writing a new program on my desktop computer or managing a website on my web server, I often need to process text files. Linux provides powerful tools that I leverage to get my work done. I frequently use sed, an editor that can modify text according to a pattern. sed stands for stream editor, and it edits text in a file and prints the results.

Not for the Linux illuminati, but a great starter Linux for non-Linux-heads. Linux Mint 21 is here, with a tweaked Ubuntu 22.04 base, natively packaged Firefox, Flatpak instead of Snap, and strategically pruned systemd.…

Mint, the best Linux desktop, gets a major update with Ubuntu 22.04 as its base and the Linux kernel 5.15.

Techbase is a Polish-based company tackling global chip shortage and supply chain issues with a remote platform to speed up development. As of now, the devices offered for remote access are the ModBerry 500 CM4 and the ClusBerry-2M. The ModBerry 500 CM4 is an industrial computer based on the Raspberry Pi CM4 powered by the […]

In my previous article about rustup, I showed you how to install the Rust toolchain. Well, what good is the toolchain if you won’t be using it to get more hands-on with Rust? Learning any language involves reading existing code and writing a lot of sample programs. That's a good way to become proficient in a language. However, there's a third way: debugging code.

No one wants to write bad code, but inevitably bugs will be created. Most modern languages like Java, JavaScript, Python, etc., automatically print a stack trace when they encounter an unhandled exception, but not shell scripts. It would make it much easier to find and fix bugs in shell scripts if you could print a stack trace, and, with a little work, you can.

Here at Mozilla, we are the first to admit the internet isn’t perfect, but we are also quick to point out that the internet is pretty darn magical. The internet opens up doors and opportunities, allows for people to connect with others, and lets everyone find where they belong — their corners of the internet. […]

CRob, with Intel and the OpenSSF, talks about open source software security education and training with Alan Shimel of TechStrong TV.

Unix has always excelled at processing text, and Linux is no different. And the tools to work with and transform text files still exist on all Linux systems. Like other computer systems, early Unix printed on paper, using a typewriter-style printing device. These printers provided limited formatting options, but with clever application of Unix tools, you could prepare professional-looking documents.

Managing files in a graphical desktop like GNOME or KDE is an exercise in point-and-click. To move a file into a folder, you click and drag the icon to its new home. To remove a file, you drag it into the “Trash” icon. The graphical interface makes desktop computing easy to use. But we don't always interact with Linux systems with a graphical interface. If you work on a server, you likely need to use the command line to get around.

A few weeks ago, HP joined the bandwagon of major laptop manufacturers releasing a Linux-based laptop, the HP Dev One. The brand joins others such as Lenovo and Dell, offering a laptop with a pre-installed distribution of Linux in the US market. HP joined forces with smaller Linux-based laptop brand System76 to pre-install Pop!_

Nowadays, Linux systems are considered fairly secure, as people think that Linux rarely gets infected with malware such as viruses, rootkits, worms, etc. You might also see that we hardly ever come across Antivirus software being sold for Linux, giving the illusion that Linux is an ultimately secure Operating System. Given that roughly 75 percent of the world's servers run on Linux, we can't truly believe that Linux is as secure as we think it is. Linux is only as secure as the person controlling and configuring it.

In a previous article, I showed you how to build your very own Nextcloud server. In this article, we're going to extend the storage for our Nextcloud instance by utilizing block storage. To follow along, you'll either need your own Nextcloud server to extend, or perhaps you can add block storage to a different type of server you may control, which would mean you'd need to update the paths accordingly as we go along. Block storage is incredibly useful, so we'll definitely want to take advantage of this.
