The Raspberry Pi 3 and RPi 3 Compute Module are quickly expanding into the industrial touch-panel market. Here’s a guide to six RPi-based contenders. In the smart home, voice agents are increasingly replacing the smartphone touchscreen interface as the primary human-machine interface (HMI). Yet, in noisier industrial and retail IoT environments, touchscreens are usually the […]

Regular expressions can be one of the most powerful tools in your toolbox as a Linux user, system administrator, or even as a programmer. It can also be one of the most daunting things to learn, but it doesn't have to be! While there are an infinite number of ways to write an expression, you don't have to learn every single switch and flag. In this short how-to, I'll show you a few simple ways to use regex that will have you running in no time and share some follow-up resources that will make you a regex master if you want to be. read more

I had a fascinating job once that involved designing hardening procedures for systems we were going to use for security-related projects. This was probably 15 years ago, and not only were guides a little thin on the ground for the Linux distribution I was using, but what we were doing was quite niche. At first, I think I'd assumed I could just write a script to close down a few holes that originated from daemons1 that had been left running for no reasons: httpd, sendmail, stuff like that.

Klashwerks has launched a $299, gesture controlled “Raven” dashcam, security system, navigation tool, and OBD-II telematics reporting device, which runs Android on a Snapdragon 650 and offers front- and cabin-facing HD cameras. Klashwerks’ Android-based Raven dashcam and automotive computer was a hit on Indiegogo and won a CES Innovation Award. Now it’s available publicly for […]

After launching in 2017, the OpenDev Conference is now an annual event. At the inaugural event last September, the conference focus was on edge computing. This year's event, taking place May 22-23, will be focused on Continuous Integration/Continuous Deployment (CI/CD) and will be co-located with the OpenStack Summit in Vancouver.

This article enables you to discover numerous tools for porting and tuning applications for Linux on Power: an integrated development environment (IDE), compilers and toolchains, performance and utilization analysis, emulation, instruction timing, high-performance application programming interfaces, and libraries.

One of the most universally used Linux/Unix tools is now included by default in Windows 10: OpenSSH. Here's how to get started with it. Windows 10 is becoming a useful Unix/Linux sysadmin platform. First, it has incorporated Windows Subsystem for Linux in the Windows 10 Fall Creators Update. Now, in the Windows 10 April 2018 Update, Microsoft has finally brought a native Secure Shell (SSH) to Windows.

Sometimes you want to monitor what new information is being written to a file (think of log files), or for whatever reasons, want to access the last few lines of a file. Well, there's a command line utility that lets you do this in Linux, and it's call tail.

Topics such as licensing and governance are complex but nonetheless critical considerations for open source projects. The Linux Foundation’s Scott Nicholas will examine various approaches for structuring open source projects with these requirements in mind. This free, hour-long webinar (at 10:00 am Pacific, May 30, 2018) will address some of the differences that exist in community-driven governance and will explore various case studies

If you are new to this series (and to Linux), take a look at our first installment. In that article, we worked our way through the tree-like structure of the Linux filesystem, or more precisely, the File Hierarchy Standard. I recommend reading through it to make sure you understand what you can and cannot safely touch. Because this time around, I’ll show how to get all touchy-feely with your directories.

At KubeCon + CloudNativeCon in Copenhagen, Denmark recently, I met many users, technologists, and business leaders -- all aware of the dramatic pace of innovation and eager to learn about the new technologies that are coming out of open source space. With these rapid changes, many companies are now also worried about finding skilled developers who are well versed in the latest technologies.

Estone Technology (AKA Habey) has launched a Linux-friendly “EMB-2610” Pico-ITX SBC built on an Atom x5-Z8350 with WiFi, BT, and optional PoE, and also introduced 7- and 10-inch touch-panel PCs built on it.
