Analyzing the Linux boot process

Tuesday 16th of January 2018 08:02:00 AM

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.

Why building a community is worth the extra effort

Tuesday 16th of January 2018 08:00:00 AM

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.

2 scientific calculators for the Linux desktop

Monday 15th of January 2018 08:01:00 AM

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.

Dr. Lovesource: Or how I learned to stop worrying and love the open

Monday 15th of January 2018 08:01:00 AM

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.

How debuggers really work

Monday 15th of January 2018 08:00:00 AM

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.

SPDX clears confusion around software licenses

Friday 12th of January 2018 08:02:00 AM

Around this time every year, our minds turn to copyright. Or maybe they turn more to copyright. After all, open source works because of copyright law. As you may already know, copyright laws give the authors of works the exclusive right to copy (among other things) their work. These rights attach as soon as the work is fixed in a tangible medium (written down, saved to disk, etc.). So the rights that open source licenses grant rely on copyright law.

Top 5 Firefox extensions to install now

Friday 12th of January 2018 08:00:00 AM

The web browser has become a critical component of the computing experience for many users. Modern browsers have evolved into powerful and extensible platforms. As part of this, extensions can add or modify their functionality. Extensions for Firefox are built using the WebExtensions API, a cross-browser development system.

Which extensions should you install? Generally, that decision comes down to how you use your browser, your views on privacy, how much you trust extension developers, and other personal preferences.

How to install software applications on Linux

Thursday 11th of January 2018 08:02:00 AM

How do you install an application on Linux? As with many operating systems, there isn't just one answer to that question. Applications can come from so many sources—it's nearly impossible to count—and each development team may deliver their software whatever way they feel is best. Knowing how to install what you're given is part of being a true power user of your OS.

How inner sourcing saved our IT department

Thursday 11th of January 2018 08:01:00 AM

Red Hat is a company with roughly 11,000 employees. The IT department consists of roughly 500 members. Though it makes up just a fraction of the entire organization, the IT department is still sufficiently staffed to have many application service, infrastructure, and operational teams within it. Our purpose is "to enable Red Hatters in all functions to be effective, productive, innovative, and collaborative, so that they feel they can make a difference,"—and, more specifically, to do that by providing technologies and related services in a fashion that is as open as possible.

AI and machine learning bias has dangerous implications

Thursday 11th of January 2018 08:00:00 AM

Algorithms are everywhere in our world, and so is bias. From social media news feeds to streaming service recommendations to online shopping, computer algorithms—specifically, machine learning algorithms—have permeated our day-to-day world. As for bias, we need only examine the 2016 American election to understand how deeply—both implicitly and explicitly—it permeates our society as well.

What’s often overlooked, however, is the intersection between these two: bias in computer algorithms themselves.

How to build custom IoT hardware with Arduino

Wednesday 10th of January 2018 08:01:00 AM

Recently I wanted to create an Arduino-based low-power Internet of Things (IoT) device for makers, with built-in sensors that could be used to deliver sensor data from any location to the cloud, and potentially control connected devices such as thermostats, lights, door locks, and other home automation products. Along the way, I learned that creating a new IoT device, from idea to prototype to final product, is not as simple as I thought it would be, and there was no "ready-to-go" development device to start with.

Mozilla Firefox 58

  • Latest Firefox Quantum release available with faster, always-on privacy with opt-in Tracking Protection and new features
    We accept things in the online world that we wouldn’t accept in the physical one. For instance, how would you feel if you popped your head in a store and that store now had the ability to keep sending you flyers even if you didn’t buy anything? Online, we often visit sites that track us, but it isn’t clear when this is happening or how the information is being used. Adding insult to injury, this often invisible tracking actually slows down web pages.
  • Firefox 58 Arrives With Continued Speed Optimizations
    Mozilla has set free Firefox 58.0 today as their latest "Firefox Quantum" release that continues work on being a performant web browser.
  • Firefox Quantum 58 builds on performance gains, improves screenshots tool
    Mozilla is rolling out Firefox Quantum 58.0 for desktop, along with Firefox for Android 58.0. It arrives over two months after the landmark release of Firefox Quantum 57.0. The latest build focuses on performance and security, while an update to Firefox’s user profile feature means it’s no longer backwards compatible with previous versions. Android users also gain the ability to pin favorite websites to their home screen for use like native apps.
  • Firefox 58 Released for Linux, Mac, and Windows
    The Mozilla Foundation has made Firefox 58 files available for download on its official FTP servers. An official announcement will be made later today when the organization will also release the final changelog.
  • Browse without baggage in Firefox: Set Tracking Protection to always on
    We just can’t stop making Firefox faster — and with our most recent release, we also made it easier for you to control how much you’re tracked.
  • Firefox 58: The Quantum Era Continues
    2017 was a big year for Mozilla, culminating in the release of Firefox Quantum, a massive multi-year re-tooling of the browser focused on speed, and laying the groundwork for the years to come. In 2018, we’ll build on that incredible foundation, and in that spirit our next several releases will continue to bear the Quantum moniker. Let’s take a look at some of the new goodies that Firefox 58 brings.
