Why do you use Linux and open source software?

Friday 17th of March 2017 07:01:00 AM

As I mentioned when The Queue launched, although typically I will answer questions from readers, sometimes I'll switch that around and ask readers a question. I haven't done so since that initial column, so it's overdue. I recently asked two related questions at LinuxQuestions.org and the response was overwhelming. Let's see how the Opensource.com community answers both questions, and how those responses compare and contrast to those on LQ.

A lesson in accountability from my Uber driver

Thursday 16th of March 2017 07:00:00 AM

The first thing I noticed was how nice Kyle's car was. It wasn't too fancy (a late model Toyota Camry) but inside it was spotless. We were sitting in leather seats. On the back of the passenger seat, Kyle had mounted a tablet customers could use to watch TV if they wanted (not that I was particularly interested in television during this 4:30 a.m. ride to the airport).

How to build an IoT project with Mongoose OS

Wednesday 15th of March 2017 07:01:00 AM

IoT (Internet of Things) is about connecting physical objects ("things") to the Internet. Technically, this is done by attaching a computer to a "thing." A computer is attached in a way that it can read data from the thing and report to the Internet, and also it can receive commands and control the thing's state. 

Usually, the COMPUTER is directly wired to the THING, and the COMPUTER <=> INTERNET connection could be either wired (e.g., Ethernet), or wireless (e.g., Bluetooth, Wi-Fi).

What could the computer be?

The physical computing capabilities of the Raspberry Pi

Tuesday 14th of March 2017 07:03:00 AM

While the Raspberry Pi is an excellent and affordable mini Linux computer with a stylish and functional desktop user interface, it has plenty of scope beyond that of a regular PC. Here's an overview of the physical computing capabilities of the Pi.

GPIO pins

Since 2014, with the release of the Model B+, the Raspberry Pi's form factor has stayed the same, including the uniform 40-pin GPIO (General Purpose Input/Output) pin header.

Open source in death and beyond

Tuesday 14th of March 2017 07:01:00 AM

Benjamin Franklin was known to say, "In this world nothing can be said to be certain, except death and taxes." There are open source solutions for completing your taxes, such as Open Tax Solver, but what about the other side of that quote? What does open source have to do with death? It's quite a lively subject, it seems. I know you are just dying to know, so let's dig in.

3 tips for helping creative people work openly

Tuesday 14th of March 2017 07:00:00 AM

Participants in open source communities collaborate in online environments differently than they do offline.

Online, we open source enthusiasts tend to think participation is easy—as long as we're using open tools and have documented how people might get involved. We create structures, strategies, and mechanisms for soliciting peer-to-peer feedback and inviting participation. When interested people appear on our radar, we make an effort to reach out, encourage them, and see if they need help navigating our projects.

Getting started with Perl on the Raspberry Pi

Monday 13th of March 2017 07:01:00 AM

When I spoke recently at SVPerl (Silicon Valley Perl) about Perl on the Raspberry Pi, someone asked, "I heard the Raspberry Pi is supposed to use Python. Is that right?" I was glad he asked because it's a common misconception. The Raspberry Pi can run any language. Perl, Python, and others are part of the initial installation of Raspbian Linux, the official software for the board.

How to install Fedora 25 on your Raspberry Pi

Friday 10th of March 2017 08:02:00 AM

In October 2016, the release of Fedora 25 Beta was announced, along with initial support for the Raspberry Pi 2 and 3. The final "general availability" version of Fedora 25 was released a month later, and since then I have been playing around with the many different Fedora spins available for the latest versions of the Raspberry Pi.

  • Chromium/Chrome Browser Adds A glTF Parser
    Google's Chrome / Chromium web-browser has added a native glTF 1.0 parser. The GL Transmission Format, of course, being Khronos' "3D asset delivery format" for dealing with compressed scenes and assets by WebGL, OpenGL ES, and other APIs. There are glTF utility libraries in JavaScript and other web-focused languages, but Google adding a native glTF 1.0 parser appears to be related to their VR push with supporting VR content on the web. Their glTF parser was added to Chromium Git on Friday.
  • Sex and Gor and open source
    A few weeks ago, Dries Buytaert, founder of the popular open-source CMS Drupal, asked Larry Garfield, a prominent Drupal contributor and long-time member of the Drupal community, “to leave the Drupal project.” Why did he do this? He refuses to say. A huge furor has erupted in response — not least because the reason clearly has much to do with Garfield’s unconventional sex life. [...] I’ll unpack the first: open-source communities/projects are crucially important to many people’s careers and professional lives — cf “the cornerstone of my career” — so who they allow and deny membership to, and how their codes of conduct are constructed and followed, is highly consequential.

While the RepRap project is the best example we have for what can be done with Open Source hardware, the stuff that makes 3D printers work – filament, motors, and to some extent the electronics – are tied up in trade secrets and proprietary processes. As you would expect from most industrial processes, there is an art and a science to making filament and now these secrets will be revealed.

Security Leftovers

  • NSA: We Disclose 90% of the Flaws We Find
    In the wake of the release of thousands of documents describing CIA hacking tools and techniques earlier this month, there has been a renewed discussion in the security and government communities about whether government agencies should disclose any vulnerabilities they discover. While raw numbers on vulnerability discovery are hard to come by, the NSA, which does much of the country’s offensive security operations, discloses more than nine of every 10 flaws it finds, the agency’s deputy director said.
  • EFF Launches Community Security Training Series
    EFF is pleased to announce a series of community security trainings in partnership with the San Francisco Public Library. High-profile data breaches and hard-fought battles against unlawful mass surveillance programs underscore that the public needs practical information about online security. We know more about potential threats each day, but we also know that encryption works and can help thwart digital spying. Lack of knowledge about best practices puts individuals at risk, so EFF will bring lessons from its comprehensive Surveillance Self-Defense guide to the SFPL. [...] With the Surveillance Self-Defense project and these local events, EFF strives to help make information about online security accessible to beginners as well as seasoned techno-activists and journalists. We hope you will consider our tips on how to protect your digital privacy, but we also hope you will encourage those around you to learn more and make better choices with technology. After all, privacy is a team sport and everyone wins.
  • NextCloud, a security analysis
    First, I would like to scare everyone a little bit in order to have people appreciate the extent of this statement. As the figure that opens the post indicates, there are thousands of vulnerable Owncloud/NextCloud instances out there.
