Every GNOME user should do these five things to their desktop environment right away. They make a big difference and all can be accomplished in minutes.

The REST API became available in Podman two years ago, and it is still actively maintained with new features added with every release. This article explores how Podman's REST API helps you manage pods. I'll use the classic use case for a pod: a WordPress container and a MariaDB database container using Podman's native REST API.

Linus Torvalds has released version 5.19 of the project, and hailed Apple's homebrew silicon – and the Asahi Linux distribution that runs on it – for making Arm-powered computers useful for developers. In his announcement of the release, Torvalds called out work to support for the made-in-China Loongarch RISC architecture as an important step, along with "another batch of the networking sysctl READ_ONCE() annotations to make some of the data race checker code happy."

IPv6 is a good thing for the Internet in general, but I find it unnecessarily complex for use in most home and small- to medium-size businesses. Like many others, I continue to use private IPv4 address ranges for my own internal networks and those for which I have some level of responsibility. My ISP only provides IPv4 addresses anyway, so it makes no sense to use IPv6 internally when all external packets are IPv4. Besides, IPv4 is much simpler, and one of my Linux Philosophy tenets is "Find the Simplicity."

As your open source community grows or your technology becomes more complex, a skilled program manager will coordinate teams and people with intention.

The Banana Pi BPI-Bit Lite is a development board following the BPI-Bit. This tiny device is powered by the ESP32-S3 from Espressif and it features Goldfingers I/O connectors.

In this increasingly digital era, every business, no matter the size, has to be vigilant about its cybersecurity. Data breaches have become rampant over the past several years, costing even the top companies millions of dollars in damages. Hackers are always scheming to steal critical data and so, it is best to stay ahead of the game.

Never one to shy away from tootling its own trumpet, Ubuntu Linux maker Canonical has talked up the instance modification features of version 1.10 of its lightweight VM manager, Multipass.

Virtual Private Networks (VPNs) were initially created to grant workers who are remote, workers who travel, or workers who do not tend to be in the office access to the local network over an insecure network connection when they are not physically within the local network. Essentially, a VPN can be used for various reasons however, the main purpose was for the use of businesses and companies.

A few days ago, IBASE unveiled an ATX motherboard debuting the 12th Gen Intel Core processors. The MBB-1000 supports up to 128GB DDR4 RAM, four SATA ports, eight USB 3.1 ports and several other peripherals.

For the past several years, Design Thinking has been providing a way to enhance problem solving within teams, to ensure learning goals are met, and to increase team engagement. In our previous article, we discussed how we used movie posters to "pitch" our projects to stakeholders. In this article, we're going to review the many lessons we've learned from Design Thinking.

The new Banana Pi BPI-W3 comes with the powerful Rockchip RK3588 processor and useful peripherals to be used as a router board. In this case, this board brings up to 8GB of RAM, one GbE LAN port, one GbE WAN port, triple HDMI ports and large storage capacity.

Using Design Thinking, be creative in how potential projects can be discussed and shared with stakeholders, while still capturing all the key pieces of information.

Rate Limiting With nginx. This article explains how to use the nginx HttpLimitReqModule to limit the number of requests for a given session. This is useful, for example, if your site is hammered by a bot doing multiple requests per second and thus increasing your server load. With the HttpLimitReqModule you can define a rate limit, and if a visitor exceeds this rate, he will get a 503 error.

The ESP32-C3-DevKit-RUST-1 is a development board that features the RISC-V architecture through the single-core ESP32-C3 System-on-Chip (SoC). In addition to wireless connectivity, this dev kit offers a 6-DoF IMU, a Li-Ion battery charger and it can be programmed with Rust.

Some of the changes in modern kit, especially portables, seem to be intentionally obstructive to Linux users however you can mostly work around them.

When it comes to a sysadmin's daily drivers, text editors are always near the top of the list. Whether you're partial to Vi/Vim, Emacs, Nano, ed, or any of the many other options out there, you probably couldn't do your job without one of these handy tools close at hand.

ISPConfig is a hosting control panel for Linux servers that provides functions for managing websites, databases, FTP and shell users, email accounts, and DNS. In this guide, we will show you step by step how to add a website, MySQL/MariaDB database, FTP-user, and SSH-user in ISPConfig.
