Tuesday 15th of June 2021 07:01:00 AM

Data analytics is a trendy field with many solutions available. One of them is Cube.js, an open source analytical platform. You can think of Cube.js as a layer between your data sources and applications.

As the diagram below shows, Cube.js supports serverless data warehouses and most modern relational database management systems (RDBMS). You can work with any JavaScript front-end library for data visualization, and Cube.js will take care of the rest, including access control, performance, concurrency, and more.

Keep track of your IRC chats with ZNC

Tuesday 15th of June 2021 07:00:00 AM

For a bit more than a year, I've been wondering if it is possible to bolt the open source Matrix communications network to Internet Relay Chat (IRC) in such a way that I can still use my ZNC IRC bouncer without an extra proliferation of nicknames. The answer, is amusingly, yes. But first, some background.

13 open source tools for developers

Monday 14th of June 2021 07:02:00 AM

Modern developers are highly technical, opinionated, passionate, community-focused, driven, polyglot, and most importantly, empowered decision-makers. Today, developers have a say in the products being built and the tools and technologies used to build them. Most importantly, time is precious, and developers and project managers can always benefit from great efficiency. To attain great efficiency, though, you must understand the software lifecycle, and how it can be organized and manipulated.

How I teach Python on the Raspberry Pi 400 at the public library

Saturday 12th of June 2021 07:00:00 AM

After a long and tough year, I've been looking forward to once again sharing my love of Python and open source software with other people, especially middle and high school students. Before the pandemic, I co-wrote a grant to teach Python programming to middle school students using Raspberry Pi computers. Like many other plans, COVID-19 put mine on hold for over a year. Fortunately, vaccines and the improved health in my state, New York, have changed the dynamic.

How to use the FreeDOS text editor

Friday 11th of June 2021 07:02:00 AM

Editing files is a staple on any operating system. Whether you want to make a note about something, write a letter to a friend, or update a system configuration file—you need an editor. And FreeDOS provides a user-friendly text editor called (perhaps unimaginatively) "FreeDOS Edit."

Editing files

The simplest invocation of FreeDOS Edit is just EDIT. This brings up an empty editor window. The patterned background suggests an empty "desktop"—a reminder that you aren't editing any files.

To nurture open leaders, managers must learn to let go

Friday 11th of June 2021 07:00:00 AM

In my previous article on talent development in open organizations, I explained how senior and upper-level managers can help young leadership talent develop without taking an entirely "hands off" approach. The truth is that leadership talent rarely develops on its own, and if organizations wishing to become more open want to see open leaders thrive, upper management has a specific job to do.

Why choose open source for your home automation project

Thursday 10th of June 2021 07:01:00 AM

Let's face it. The point of technology is to make life better.

Of course, what qualifies as "better" varies for people, depending on what they need at any given moment. Still, technology has the unique ability to affect lives at many different stages. For some people, technology offers a relaxing afternoon of entertainment, while for others, it provides navigational assistance, improved health care, or more precise scientific research.

Install and remove software packages on FreeDOS

Thursday 10th of June 2021 07:00:00 AM

On Linux, you may have used a package manager to install or remove packages. For example, the default package manager on Debian Linux is the deb command, and the default package manager on Fedora Linux is the dnf command. But did you know that FreeDOS has a package manager, too?

Making portable functions across serverless platforms

Wednesday 9th of June 2021 07:00:00 AM

The rising popularity of serverless development alongside the increased adoption of multi- and hybrid-cloud architectures has created a lot of competition among platforms. This gives developers many choices about where they can run functions on serverless platforms—from public managed services to on-premises Kubernetes.

Purism shows off new features coming to PureOS for the Librem 5 smartphone (camera software, wireless toggles, screen rotation and more)

The next major release of the PureOS operating system that ships with the Librem 5 smartphone will bring a number of new features and improvements. Code-named Byzantium, the new version of PureOS will bring a handful of new applications plus user interface tweaks that let you do things like enable automatic screen rotation, toggle WiFi, Bluetooth, or cellular functionality, or change keyboard styles. And while some of those features are likely tied to the hardware of Purism’s $799 smartphone, it’s likely that some may eventually find their way to other Linux distributions for other phones, because Purism is the lead developer of the Phosh user interface that’s also available for other mobile Linux distributions including postmarketOS, Manjaro, Mobian, Arch, openSUSE, and Fedora.

  • The Mozilla Blog: Celebrating our community: 10 years of the Reps Program

    Mozilla has always been about community and understanding that the internet is a better place when we work together. Ten years ago, Mozilla created the Reps program to add structure to our regional programs, further building off of our open source foundation. Over the last decade, the program has helped activate local communities in over 50 countries, tested Mozilla products and launches before they were released to the public, and collaborated on some of our biggest projects. The last decade also has seen big shifts in technology, and it has only made us at Mozilla more thankful for our volunteers and more secure in our belief that community and collaboration are key to making a better internet. “As the threats to a healthy internet persist, our network of collaborative communities and contributors continues to provide an essential role in helping us make it better,” said Mitchell Baker, CEO and Chairwoman of Mozilla. “These passionate Mozillians give up their time to educate, empower and mobilize others to support Mozilla’s mission and expand the impact of the open source ecosystem – a critical part of making the internet more accessible and better than how they found it.” Ahead of our 10 year anniversary virtual celebration for the Reps Mozilla program, or ReMo for short, we connected with six of the 205 current reps to talk about their favorite parts of the internet, why community is so important, and where the Reps program can go from here.

  • Some notes on Firefox's media autoplay settings as of Firefox 89

    The basic control for media autoplaying (for video and audio) is in Preferences → Privacy & Security, as covered in Allow or block media autoplay in Firefox. As mentioned there, if you want to block all videos you want 'block audio and video', not just 'block audio', which only blocks videos with un-muted audio and still allows silent ones to autoplay if they want to. This appears to affect everything, including bare video content such as direct links to .mp4s, which is a change from 2018. The limitation of this setting is that by itself, once you click to play a video in a tab, (auto)playing stays enabled until you close the tab again. So once you've let the first Youtube video play, Youtube (or anywhere else) will autoplay as much else as it wants to (in that tab). I prefer to specifically play each video.

  • How the X Window System Influenced Modern Computing

    I should probably wait five years to write this article, so that I could frame it as a eulogy on the death of the Graphical User Interface (GUI). Not too long from now, we will interact with highly intelligent computerized agents using speech, gestures, and wearable devices. But right now, the GUI is still the most common way to interact with a computer, even if keyboards and mouse clicks are augmented by swipes, voice recognition, and autofill. The X Window System, in addition to presenting an important and historic GUI, also exemplified other important trends that made modern computing possible.

  • Control AMD's Wraith cooler RGB on Linux using Wraith Master with a new release | GamingOnLinux

    Have a fancy AMD CPU with a Wraith Prism cooler? You might want to adjust some of the RGB settings on Linux and for that you should check out Wraith Master. What it is: Wraith Master is a feature-complete graphical and command-line application for controlling the RGB LEDs on AMD's Wraith stock coolers. At the moment, the only supported cooler is the Wraith Prism, but there are plans to add other Wraith coolers as well. It exists as an independent companion to OpenRGB, and is designed to provide control over all functionality exposed by the hardware. In summary: it's lightweight, it's native, it's fast, it's complete, and it's self-contained.

  • No, Windows is not copying KDE Plasma

    Every so often there appear some new pics from developer builds of Windows or even leaks such as the recent Windows 11 preview screenshots. More or less every time this happens there are comments from the Linux side that Windows is copying KDE Plasma – a desktop environment that is, granted, among the most similar ones to Windows. The similarity is, however, only very superficial. To convince you of this, in this post I’ll dissect several design elements and show how the two competitors differ in approaching them. [...] The design in newer parts of Windows is almost nothing like Plasma. To say that Windows is copying Plasma is pretty wrong. The Windows 11 changes actually further separate the two, rather than bring them closer. The changes also highlight the differences in the approaches underlying design choices: Plasma is more conservative and Windows is more progressive.

  • GMK NucBox Review - A palm-sized Windows 10 mini PC - CNX Software

    Whilst a detailed comparison between the two operating systems is beyond the scope of this review, it is worth noting some of the key findings I observed. Looking at the performance tools common between the two OS showed that they were reasonably evenly matched. However, as the fan is not detected under Ubuntu and video playback on WIndows runs better than on Ubuntu, given the price includes a Windows 10 Home license it probably doesn’t make too much sense to use the device as a Linux HTPC.
