The recently revealed Boothole bug in Grub2, a bootloader used by almost all Linux distributions, has been fixed. But while it's getting headlines, it can only successfully attack a handful of already vulnerable systems. Given the need for root access to the bootloader, the described attack appears to have limited relevance for most cloud computing, data center, and personal device scenarios, unless these systems are already compromised by another known attack.

Modern Linux systems often use systemd as their init system and manager for jobs and many other functions. Services managed by systemd generally send their output (of all forms: warnings, errors, informational messages, and more) to the systemd journal, not to traditional logging systems like syslog. read more

When you're a systems administrator, you don't just have one job; you have ALL the jobs, and often each one is on-demand with little to no warning. Unless you do a task every day, you may not always have all the commands and options you need in mind when you need them. And that's why I love cheat sheets. Cheat sheets help you avoid silly mistakes, they keep you from having to look through pages of documentation, and they keep you moving efficiently through your tasks. I've selected my favorite 10 cheat sheets for any sysadmin, regardless of experience level. read more

As part of my role as a principal communication strategist 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 three of my and their favorite articles from that update.

Linear Computing has posted specs for two carrier boards with optional enclosures that support Toradex’s Linux-driven i.MX8M Mini and Nano based Verdin modules: a general purpose “VSC-4436” and a “VBB-4449” DAQ controller. While reporting this week on Toradex’s Dahlia carrier board for its Verdin modules, we saw that Ontario-based Linear Computing, Inc. (LCI) had posted […]

Documentation is an essential part of making any open source project useful to users. But it's not always developers' top priority, as they may be more focused on making their application better than on helping people use it. This is why making it easier to publish documentation is so valuable to developers. In this tutorial, I'll show you one option for doing so: combining the Docsify documentation generator with GitHub Pages.  read more

The GNOME desktop environment has been through many changes since its initial release in March 1999. For most of this time, the open source project has issued updates twice a year, which gives users predictability in when they can expect new features to land on their Linux and other Unix-like desktops. Its latest release, GNOME 3.36, came out in March, and the project is preparing to issue its next iteration in September. To learn about what's new in GNOME, I spoke with Emmanuele Bassi. read more

This final part to the series demonstrating Perl with Tic-Tac-Toe provides a module to make the computer even smarter – perhaps too smart! Can you beat it?

A job creates one or more Pods to perform a particular operation and ensures the pods successfully terminate. When a specified number of pods successfully complete, the job is complete. When a job is deleted, it deletes the Pods it created. A Job can also be used to run multiple Pods in parallel.

When I entered the engineering program as a freshman in college, I felt like a frivolous teenager. In my sophomore year, and in a fortunate stroke of serendipity, I joined Zairza, a technical society for like-minded students who collaborated and built projects separate from the academic curriculum. It was right up my alley. Zairza provided me a safe space to learn and grow and discover my interests. There are different facets and roadways to development, and as a newbie, I didn't know where my interests lay. read more
