In this article, we introduce below: an Apache 2.0 licensed resource monitor for modern Linux systems. below allows you to replay previously recorded data. Background One of the kernel’s primary responsibilities is mediating access to resources. Sometimes this might mean parceling out physical memory such that multiple processes can share the same host. Other times […]

The Linux cron system is a time-tested and proven technology. However, it's not always the right tool for system automation. There are a few other open source projects out there that can be used either in conjunction with cron or instead of cron.

In this guide, you will learn how to install Nextcloud on the Rocky Linux 8.4. You will be installing Nextcloud under the LAMP Stack (Linux, Apache2/httpd, MySQL/MariaDB, and PHP).

Sometimes a programming cure is worse than the disease. That's the case with this Linux glibc security bug.

In this guide, we will show you step-by-step how to install a 64-bit version of Rocky Linux 8.4 as a stand-alone server. Additionally, we will verify the installation by accessing the Rocky Linux server through SSH from another machine.

There are several third-party libraries for command-line argument parsing, but the standard library module argparse is no slouch either. Without adding any more dependencies, you can write a nifty command-line tool with useful argument parsing. Argument parsing in Python When parsing command-line arguments with argparse, the first step is to configure an ArgumentParser object. This is often done at the global module scope since merely configuring the parser has no side effects. read more

Mkcert is a free, simple, and very useful tool that allows you to create a locally trusted certificate without buying it from the real CA. In this post, we will show you how to create a trusted SSL certificate for local development using Mkcert on Ubuntu 20.04.

"No one has TWO television sets." Perhaps you remember that line out of that 1980s movie. Well, if your hardware looks more like something out of the sequel then you might find barrier useful for managing all that equipment.

Pine64’s upcoming “PineNote” E-ink tablet will run Linux on a Rockchip RK3566 and offer a 10.1-inch, 1404 x 1872 grayscale touchscreen plus 4GB LPDDR4, 128GB eMMC, mics and speakers, USB Type-C, WiFi 5, and an EMR pen. More so than other community-backed hacker board projects, Pine64 experiments with alternative open-spec form factors in addition to […]

Computers are good at automation, but not everyone knows how to make automation work. It's a real luxury, though, to be able to schedule a task for a computer at a specific time and then forget about it. Maybe you have a file to upload or download at a specific time, or you need to process a batch of files that don't yet exist but are guaranteed to exist by a certain time or a setting that needs monitoring, or maybe you just need a friendly reminder to pick up bread and butter on the way home from work. read more

Industry leaders come together to drive the growth of eBPF as a transformational technology to redefine networking, security, tracing and observability SAN FRANCISCO, August 12, 2021 – The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced that it is hosting the eBPF Foundation. Founding members include Facebook, Google, Isovalent, Microsoft […]

The eBPF program started as just a network filter, but it's become Linux's swiss-army knife tool and now its future will be in the hands of the eBPF Foundation.

MiTac’s “PD10EHI,” DFI’s “EHL171/EHL173,” and ASRock’s ”IMB-1004” thin Mini-ITX boards extend Intel’s 10nm Atom x6000 with triple displays, USB 3.1 Gen2, SATA, M.2, and PCIe. DFI and ASRock also offer 2.5GbE. Earlier this week, ICP Germany announced a thin Mini-ITX PD10EHI board with Elkhart lake (Atom x6000, etc.) from its manufacturing partner MiTac, but the […]

A couple of weeks ago, the good folks at Linux Mint released version 20.2 of their open source operating system. The installer built into the live ISO is excellent and only requires a few clicks to install the OS. You even have a built-in partitioner if you want to customize your partitions.

C is a high-level language with close-to-the-metal features that make it seem, at times, more like a portable assembly language than a sibling of Java or Python. Among these features is memory management, which covers an executing program's safe and efficient use of memory. This article goes into the details of memory safety and efficiency through code examples in C and a code segment from the assembly language that a modern C compiler generates.

When you enter a command into your terminal, whether it's to launch a GUI app or just a terminal app, there are often options (sometimes called switches or flags) you can use to modify how the application runs. This is a standard set by the POSIX specification, so it's useful for a Java programmer to know how to detect and parse options.
