Open source licenses: What, which, and why

Filed under
OSS

Most people have at least heard of open source software by now—and even have a fairly good idea of what it is. Its own luminaries argue incessantly about what to call it—with camps arguing for everything from Free to Libre to Open Source and every possible combination of the above—but the one thing every expert agrees on is that it's not open source (or whatever) if it doesn't have a clearly attributed license.

You can't just publicly dump a bunch of source code without a license and say "whatever—it's there, anybody can get it." Due to the way copyright law works in most of the world, freely available code without an explicitly declared license is copyright by the author, all rights reserved. This means it's just plain unsafe to use unlicensed code, published or not—there's nothing stopping the author from coming after you and suing for royalties if you start using it.

Ethical Code Hosting Services in 2020

Filed under
Development
Software

I was really inspired by Free Software Foundation's list of ethical repositories in which I saw GitLab.com service there among other old longstanding services. The Foundation (often called FSF) is a serious organization with long consideration if they wish to update that list. However, in fact, there are many more services coming by time and now there are several interesting ones worth to try and enjoy. Although I myself am not a programmer, but code hosting is not unfamiliar to me, as a free software community member (just like you all, dear readers) I often get so many useful information and sometimes submit bug report to projects I love. You can, for example, take information here as reference to host a Git server software at your home as you see perhaps many serious projects also using it. As an author and mere free software user, I hope this list could be useful for everybody and particularly for programmers. Happy hacking!

Games: Space Grunts 2, Death and Taxes, Oxygen Not Included

Gaming
  • Space Grunts 2 shows how versatile a deck-builder can be and it's good

    With how popular deck-builders have become, it's no surprise to see many developers have a go at it. Orangepixel have with Space Grunts 2 and after playing it, I'm really enjoying it. Note: Key provided by the developer.

    Currently in Early Access, released there back in September 2019 the developer seems to just keep adding more to it nearly every week. Given how many updates it's had, I took it for a spin to get some early thoughts on it. Space Grunts 2 has been, at least so far, one of the most unique feeling roguelikes thanks to their deck-building mechanic. Like other great roguelikes it's turn-based so nothing happens until you move, you take turns on the combat, and if you die and you need to start again. However, as you travel you collect cards which are you abilities.

  • The afterlife is an office job of choosing who lives and dies in Death and Taxes

    Placeholder Gameworks (great name!) have just recently released Death and Taxes, a game set in the afterlife where you take on the role of the Grim Reaper only it's not quite what you expect. Note: Key sent by the developer to our Steam Curator.

    Rather than go out dressed in a hooded-robe with a great big scythe, it's an office job. You get to give the stamp of approval on who lives and dies to keep chaos in check, based on people in life-threatening situations with your actions having certain consequences based on who sticks around. Inspired by the likes of "Papers, Please", "Reigns" and "Beholder".

  • Oxygen Not Included still 'fully in development' with first DLC hopefully this Autumn

    Klei Entertainment have given an update on their plans for continued support of the colony survival/building game Oxygen Not Included and they confirmed it's still 'fully in development'.

    Although it left Early Access back in July last year, since then they've been somewhat quiet on their wider plans. Not entirely silent though as they did release the "Meep's Manadatory Recreation Content Pack" free update, along with a big update to the Unity version used. Thanks to a recent roadmap post, we now know what their further plans are.

    For the first major DLC, they said it's going to be "quite sizable" with new game systems included. However, they're not giving a definite timeline on it as they're still testing and iterating on their ideas. They did at least give something of a release window, with something to show in the Summer to possibly release in the Autumn.

The Future of the Arch Linux Project Leader

Linux

Some of you may know me from the days when I was much more involved in Arch, but most of you probably just know me as a name on the website. I’ve been with Arch for some time, taking the leadership of this beast over from Judd back in 2007. But, as these things often go, my involvement has slid down to minimal levels over time. It’s high time that changes.

Arch Linux needs involved leadership to make hard decisions and direct the project where it needs to go. And I am not in a position to do this.

  • Why Huawei Without Google Is Not The End, But The Start Of Something New [Ed: Huawei already puts GNU/Linux on some major products]

    Last year, Huawei strapped in for a rough ride when US President Donald Trump called for a trade ban on the Chinese tech giant.

    Huawei was placed on the US’ Entity List since May 2019, stopping them from doing business with American companies unless granted approval by the US Government.

    The move essentially cut Huawei off from their US supply of parts, such as the latest chips by Intel and Qualcomm — but the greatest impact felt was definitely losing access to Google’s licensed software, apps and services.

    The one question boggling fans and users was what would happen when future Huawei phones come without Google’s Android and Google Mobile Services (GMS) like Gmail, Google Chrome and Google Maps?

  • Ksnip is a cross-platform, open source screenshot tool with many annotation options

    The program supports five modes for capturing screenshots. Rectangular Area is the default one which was mentioned in the above paragraph. The second option is Last Rectangular Area, selecting this option directly captures the content inside the previous area that you chose. This is a rather unusual option, and quite a useful one as it allows you to retake a screenshot or take another one in case something changed inside the rectangle.

    The Full Screen mode can be used to save a snapshot of the entire screen. What's special here is that, Ksnip can capture the screen from all connected monitors. So, you can use it to take wide screenshots from videos, games and maybe even set the captured image as your desktop background wallpaper.

  • Open Source textbooks saving Beaufort County Community College students money
  • Open-source textbooks save Beaufort students over $50,000 per semester

    Open source textbooks are helping students at Beaufort County Community College save money, making the cost of their education less expensive and helping stretch financial aid or scholarship money they may be receiving.

    The average student will spend over $1,200 on textbooks per year. Since initial adoption by Ashleigh Howard, Lead Professor for the Social & Behavioral Sciences Department, the books have been adopted by other professors across campus, cumulatively saving students over $50,000 per semester. Currently, cultural geography, history, criminal justice, sociology and Spanish classes are using the books.

  • UBank puts open source accessibility kit on GitHub [Ed: This feeds a proprietary software trap of Microsoft for openwashing purposes and to make matters worse, it is not accessible]
  • Precious Plastic open source recycling project takes a new perspective toward waste

    “Plastic is a precious and valuable material. It’s just been kind of designed, used and marketed in the wrong way, in our view,” explained Precious Plastic business guy (yes, that’s his real title) Joseph Klatt. The company’s business guy is originally from Ohio but moved to the Netherlands where the project is headquartered.

  • The open source platform empowering creatives to turn recycling into craft [Ed: This use of the term "open source" may be misleading]

    In response to this, Hakkens looked to the large-scale recycling plants that operate across the world. Their huge industrial machines then formed the base of the Precious Plastic operation.

    “He began recreating these machines on a small scale, putting the blueprints and assembly instructions online for others to use,” continues Elleke.

    Once built, users can create with the waste plastic however they need, making anything from furniture and household goods, to bricks and other modular structures. The possibilities, she says, are endless: “Anything made with plastic, can be made with recycled plastic.”

    According to Elleke, the whole idea was to “take a global problem, and find a community solution.” In giving a second, third or infinite number of lives to waste plastic, Hakkens and his team provide local designers, craftspeople and creatives with a new material and profit stream.

    Dell combines several open source streaming data technologies, including Apache Kafka, Apache Flink and Pravega, to create a new streaming data platform.

  • Instaclustr Achieves PCI-DSS Certification for its Managed Apache Cassandra and Kafka Offerings on AWS
  • Democratizing space exploration with new technologies

    Democratization means nothing without the support of and collaboration with public consumers and talent. Open source software, whose source code anyone can peruse, modify and contribute to, allows NewSpace industries to engage directly with the public through hands-on, widely accessible opportunities that help develop and improve technology.

    The Massachusetts Institute of Technology (MIT) is a big proponent of these open access projects, finding that they build online and in-real-life communities and help shape the future of NewSpace tech.

    These open access resources solicit submissions from all over the world, inviting users to send their personal research concept to space. Participants, for example, can rent time on a cubesat constellation (similar to buying time on a cloud computing system). Here they can interact in open science communities with access to libraries and maker studios where users can utilize MIT’s already vast research portfolio. On top of it all, the initiative offers other integrated support systems like a STEAM outreach program with educational resources, curriculum and DIY hacker guidelines for climate-smart cubesats.

  • Collaboration Over Competition: How Companies Benefit from Open Innovation

    More and more technology companies are adopting open innovation initiatives. This is largely due to the realization of the benefits of working with outside experts to gain external perspectives and insights. This situation wherein an organization thinks beyond its internal resources for innovation and collaborates with external resources is known as open innovation. Open innovation is an opportunity for the company to utilize those external ideas and use them to develop innovative products and services. It may seem simple, but there is more to the collaboration process than just brainstorming.

  • An Open Source Ebike

    In the ebike world, there are two paths. The first is a homemade kit bike with motors and controllers from China. The second is a prebuilt bike from a manufacturer like Giant, with motors and controllers from China, which will be half as fast and cost three times as much. The choice is obvious, and there are other benefits to taking the first path as well, such as using this equipment which now has an open source firmware option.

    This new open source firmware for the TSDZ2 further improves on the ride by improving the motor responsiveness, improving battery efficiency, and opening up the ability to use any of a number of color displays. (More information is available on a separate Wiki.)

  • What developers need to know about domain-specific languages

    A domain-specific language (DSL) is a language meant for use in the context of a particular domain. A domain could be a business context (e.g., banking, insurance, etc.) or an application context (e.g., a web application, database, etc.) In contrast, a general-purpose language (GPL) can be used for a wide range of business problems and applications.

    A DSL does not attempt to please all. Instead, it is created for a limited sphere of applicability and use, but it's powerful enough to represent and address the problems and solutions in that sphere. A good example of a DSL is HTML. It is a language for the web application domain. It can't be used for, say, number crunching, but it is clear how widely used HTML is on the web.

    A GPL creator does not know where the language might be used or the problems the user intends to solve with it. So, a GPL is created with generic constructs that potentially are usable for any problem, solution, business, or need. Java is a GPL, as it's used on desktops and mobile devices, embedded in the web across banking, finance, insurance, manufacturing, etc., and more.

  • Raspberry Pi 4 Rev 1.2 Fixes USB-C Power Issues, Improves SD Card Resilience

    The first Raspberry Pi 4 boards suffered from a poor USB-C power supply compatibility due to issues for the power circuitry. That means if you bought the official USB-C power supply you had no issues, but if you wanted to re-use a spare USB-C power supply or incompatible cable, you may be out of luck.

  • Using C and C++ for data science

    I wrote about my motivation for continually learning languages in an article covering Python and GNU Octave, which is worth reviewing. All of the programs are meant to be run on the command line, not with a graphical user interface (GUI). The full examples are available in the polyglot_fit repository.

I discovered the PyData/Sparse project back then (it was in Matthew Rocklin’s personal repository at the time), and was immediately fascinated by the idea of computational gains to be had if one moved to a sparse representation. I’m now the maintainer for that project, and I’m grateful I chose that path, as it landed me a talk at SciPy 2018 and a client in the form of Quansight.

Red Hat: Systemd, PulseAudio, Survey and OpenStack

Red Hat
  • Where I Stand on Systemd

    Once I turn to design considerations and technological benefits, however, I quickly bog down. The Unix philosophy of one utility to do one thing very well sounds admirable in theory, and perhaps on the administrative level it works well. Yet, I have heard few if any complaints that large apps like SE Linux or AppArmor violate the Unix philosophy, and on the desktop, apps like LibreOffice or Krita are clear violators. Could it be that some projects require a different approach to be effective?

    As a user, my initial tendency is to applaude Init Freedom’s rejection of “this one-size-fits-all vision” that led to the general acceptance of systemd in the major distributions. Yet as I think further, I wonder how practical supporting multiple init systems might be.

    In the recent Debian general resolution on systemd, both sides maintained that expecting maintainers to support multiple init systems would seriously add to the task of keeping packages current. The Devuan project itself appears to illustrate the difficulty, since it still uses Debian 9 as its basis and so far has been unable to add multiple init support itself. When finding maintainers is a constant problem for many distros, perhaps a limit on the number of supported init systems is sheer practicality.

  • PulseAudio 14 Is Releasing Soon With Better USB Gaming Headset Support

    In addition to PipeWire 0.3 having shipped last week, also making it out a few days prior was a development snapshot in the road to PulseAudio 14.0.

    In the 6+ months since PulseAudio 13, developers have been working on various audio sink changes, automatic switching to HDMI audio is now disabled by default, flat volumes are also disabled by default, there is better support for USB gaming headsets, PulseAudio honoring Xauthority arguments for X11 modules, a workaround for GNOME Sound Settings behavior, and various other changes.

  • Enterprise open source software is growing within innovative companies

    Red Hat has been at the forefront of the global open source discussion, fighting for software freedom in the U.S Supreme Court, and offering free tech products for cloud infrastructure, automation, AI, and much more. After conducting research and interviewing IT leaders from around the world, Red Hat released a report examining the state of enterprise open source in 2020.

    950 IT leaders, unaware that Red Hat was the research sponsor, were surveyed about their practices and opinions on enterprise open source software.

    [...]

    The benefits of using open source software seem obvious, namely that they are, of course, freely available. However, its lack of a price tag isn’t the main thing that IT leaders love.

    According to the survey, respondents believe that higher-quality software is the number one benefit of enterprise open source. FOSS software is often better than proprietary options, with better security, cloud-native technologies, and cutting edge solutions.

  • Red Hat OpenStack Platform 16 Delivers Long-Term Support

    On Feb. 20, Red Hat announced OpenStack Platform 16, a major update providing up to five years of support.

Up until the OpenStack 15 release in September 2019, Red Hat released two minor updates every year that had up to one year of support, followed by a major long-term support release. As of the Red Hat OpenStack Platform 16 release, there will now only be long-term support releases.

Excellent System Tools: nnn – portable terminal file manager

Filed under
GNU
Linux
Software

I’m devoting most of my spare time writing about the Raspberry Pi 4 (RPI4). My findings are captured in a weekly blog chronicling my experience of using the tiny machine as a desktop replacement. One of my forthcoming blog posts examines file managers on the RPI4 looking at both graphical and terminal-based file managers.

As I’ve spent a lot of time using nnn in the past few weeks, it makes sense I look at the latest release on a regular Intel machine, in advance of my RPI4 file manager blog.

LinuxLinks has previously reviewed imgp and googler. They are open source software coded by Arun Prakash Jana. He’s also the developer of nnn which has seen a new major release in the past fortnight. I’ve never reviewed any of Mr Jana’s software before.

How does the author describe his software? His man page says “nnn is the missing terminal file manager for X. (Nnn’s Not Noice) is a performance-optimized, feature-packed fork of noice with seamless desktop integration, simplified navigation, navigate-as-you-type mode with auto select, disk usage analyzer mode, bookmarks, contexts, application launcher, familiar navigation shortcuts, subshell spawning and much more. It remains a simple and efficient file manager that stays out of your way.”

In a single sentence, nnn can be probably best summarized as software seeking to bridge the gap between the terminal and the desktop environment.

The NG in vokoscreenNG stands for New Generation and rightly so because it’s been created from scratch using Qt and Gstreamer.

Or it was until fresh new editors, like Atom, VSCode, and Brackets, came to the fresh new open source landscape of today. There are so many options for robust text editors now, many of which have iterated upon Emacs' ideas and traditions, that you may well wonder whether GNU Emacs is still relevant.
