When we launched Nethesis in 2003, we were just system integrators. We only used existing open source projects. Our business model was clear: Add multiople forms of value to those projects: know-how, documentation for the Italian market, extra modules, professional support, and training courses. We gave back to upstream projects as well, through upstream code contributions and by participating in their communities. read more

The oldest joke in open source software is the statement that "the code is self-documenting." Experience shows that reading the source is akin to listening to the weather forecast: sensible people still go outside and check the sky. What follows are some tips on how to inspect and observe Linux systems at boot by leveraging knowledge of familiar debugging tools. Analyzing the boot processes of systems that are functioning well prepares users and developers to deal with the inevitable failures. read more

CompuLab’s rugged, 68 x 42mm “CL-SOM-iMX8” module runs Yocto or Android on NXP’s dual- or quad-core Cortex-A53 i.MX8M, with up to 4GB LPDDR4, up to 64GB eMMC, onboard wireless, and PCIe and HDMI 2.0 support. CompuLab’s CL-SOM-iMX8 module, which ships with an optional SBC-iMX8 Evaluation Kit, shares many features with Variscite’s recently announced DART-MX8M module, […]

I used to write code. I don't anymore. There are lots of reasons for this, including the fact that I wasn't very good at it. To clarify, I was, I think, good at writing code,1 but I wasn't very good at writing code.2 It turns out that I'm quite good at a variety of other things, so my career3 moved in a different direction—or, in fact, a variety of different directions.

Every Linux desktop environment comes with at least a simple desktop calculator, but most of those simple calculators are just that: a simple tool for simple calculations. Fortunately, there are exceptions; programs that go far beyond square roots and a couple of trigonometric functions, yet are still easy to use. Here are two powerful calculator tools for Linux, plus a couple of bonus options. read more

The alliance announced the Wi-Fi Protected Access 3 (WPA3), a new standard of Wi-Fi security that greatly increases the security capabilities of the wireless standard. WPA2, which is the current standard in wireless security, has been around for 14 years, so this is way overdue.

A debugger is one of those pieces of software that most, if not every, developer uses at least once during their software engineering career, but how many of you know how they actually work? During my talk at linux.conf.au 2018 in Sydney, I will be talking about writing a debugger from scratch... in Rust! In this article, the terms debugger/tracer are interchangeably. "Tracee" refers to the process being traced by the tracer. read more
