I am teaching Python using Raspberry Pi 400 computers in a local library for the second year in a row. A couple of this year's students have not experienced success with mathematics in their school. One asked me if she needed algebra to attend our class. I told her I had failed algebra, geometry, and trigonometry in school. She was relieved.

The latest long-term support version of Ubuntu receives its first upgrade.

Ruchi Pakhle shares his experience in the Linux Foundation's mentorship program working with Open Horizon.

Java is a platform-independent language. Programs are converted to bytecode after compilation. This bytecode gets converted to machine code at runtime. An interpreter emulates the execution of bytecode instructions for the abstract machine on a specific physical machine. Just-in-time (JIT) compilation happens at some point during execution, and ahead-of-time (AOT) compilation happens during build time.  This article explains when an interpreter comes into play and when JIT and AOT will occur. I also discuss the trade-offs between JIT and AOT.

If you're sharing files between two users over the network or "sneaker net" (saving a file to a hard drive and copying it to a computer), you may encounter permission errors when you try to read or write the file. Even if you understand the concept of file permissions, you may not know exactly how to diagnose the problem or solve it. I used to perform data migration as a service, so I've run into my fair share of permission errors and ownership conflicts. Here's how I fix them fast.

Git back, git back, git back to where your files belong. GitLab is chewing on life's gristle. The problem, we hear, is that deadbeat freeloaders are sucking up its hosting lifeforce. The company's repo hive is clogged with zombie projects, untouched for years but still plugged into life support. It's costing us a million bucks a year, sighed GiLab's spreadsheet wranglers, and for what? …

Don't panic if you're not a fan of big changes… it's 5.20 by another name. The next version of the Linux kernel is jumping version numbers, with some performance gains, but it's not a major change all the same.…

"Why Clojure?" is probably the question we've been asked the most at Penpot. We have a vague explanation on our FAQ page, so with this article, I'll explain the motivations and spirit behind our decision. It all started in a PIWEEK. Of course!

One of my favorite stories about Unix is how it turned into a text processing system. Brian Kernighan tells the story in his book Unix: A History and a Memoir (chapter 3) but to summarize: The Unix team at Bell Labs ran the original Unix on a PDP-7 computer, but it was a tiny system and didn't have sufficient resources to support new work.

The Firefly Station M3 is a Mini PC built around the eight-core Rockchip RK3588S System on Chip (SoC) released this year. This fanless Mini PC comes in an aluminum case and it can support up to 16GB of RAM and 128GB of eMMC flash. The Rockchip RK3588S SoC combines four Cortex-A76 cores, four Cortex-A55 cores, […]

The past three years have redefined the practice and management of public health on a global scale. What will we need in order to support innovation over the next three years?

In the first article of this series, Get started with NetworkManager on Linux, I looked at what NetworkManager does and some of the tools it provides for viewing network connections and devices. I discussed using the nmcli command to view the status of network devices and connections on a host.

Now makes vague pledge to shove inactive repos into slow object storage. GitLab has reversed its decision to automatically delete projects that are inactive for more than a year and belong to its free-tier users.…

Global visionaries headline the premier open source event in Europe to share on OSS adoption in Europe, driving the circular economy, finding inspiration through the pandemic, supply chain security and more. SAN FRANCISCO, August 4, 2022 —  The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced the keynote speakers for […]

Years after the company quit server virtualization, but may be handy for hybrid work. Citrix has added a development stream to its hypervisor that promises fast and frequent enhancements, plus a cloud service to deliver them to users.…

So far, ownCloud users have only had the opportunity to choose between simple local file storage based on a POSIX-compatible file system or EOS Open Storage (EOS). The latter causes massive complexity during setup. More recent versions of ownCloud feature a functionality called Decomposed FS. This file system is supposed to bring oCIS to arbitrary storage backends and even scalable ones.

After you merge a GitLab or GitHub pull request, you usually delete the topic branch in the remote repository to maintain repository hygiene. However, this action deletes the topic branch only in the remote repository. Your local Git repository also benefits from routine cleanup. To synchronize the information in your local repository with the remote repository, you can execute the git prune command to delete the local reference to a remote branch in your local repository.

I have bigger problems than where you put our code. On Call Be careful where you install stuff, and who is doing the installing. Welcome to an On Call in which normal service is interrupted by a military intervention.…
