Sponsored development is a win-win for users and developers

22 hours 53 sec ago

There is a myth that simply by making a software platform open source, qualified people will give up their nights and weekends to contribute to its development. With rare exceptions, that's not how the open source world works. Building a community of contributors takes time, and complex applications often have a steep learning curve before a developer becomes comfortable working with the code.

10 things I learned about making LEGO bricks glow

22 hours 1 min ago

By day, Jen Krieger is chief agile architect at Red Hat, but by night she architects stunning LEGO creations, including a Parisian café she demonstrated in her All Things Open 2017 Lightning Talk, "10 Things I Learned About Making LEGO Bricks Glow."

Jen wanted to add lighting to her LEGO model, but in the open source maker tradition, she wanted to do it herself instead of simply ordering a pre-fab LEGO lighting kit.

Open education: How students save money by creating open textbooks

Wednesday 22nd of November 2017 08:00:00 AM

Most people consider a college education the key to future success, but for many students, the cost is insurmountable. The growing open educational resource (OER) movement is attempting to address this problem by providing a high-quality, low-cost alternative to traditional textbooks, while at the same time empowering students and educators in innovative ways. One of the leaders in this movement is Robin DeRosa, a professor at Plymouth State University in New Hampshire.

7 tools for analyzing performance in Linux with bcc/BPF

Tuesday 21st of November 2017 08:03:00 AM

A new technology has arrived in Linux that can provide sysadmins and developers with a large number of new tools and dashboards for performance analysis and troubleshooting. It's called the enhanced Berkeley Packet Filter (eBPF, or just BPF), although these enhancements weren't developed in Berkeley, they operate on much more than just packets, and they do much more than just filtering. I'll discuss one way to use BPF on the Fedora and Red Hat family of Linux distributions, demonstrating on Fedora 26.

An introduction to machine-learned ranking in Apache Solr

Tuesday 21st of November 2017 08:02:00 AM

This tutorial describes how to implement a modern learning to rank (LTR, also called machine-learned ranking) system in Apache Solr. It's intended for people who have zero Solr experience, but who are comfortable with machine learning and information retrieval concepts. I was one of those people only a couple of months ago, and I found it extremely challenging to get up and running with the Solr materials I found online.

Why the open source community needs a diverse supply chain

Tuesday 21st of November 2017 08:00:00 AM

At this year's Opensource.com Community Moderator's meeting in Raleigh, North Carolina, Red Hat CEO Jim Whitehurst made a comment that stuck with me.

"Open source's supply chain is source code," he said, "and the people making up that supply chain aren't very diverse."

Diversity and inclusivity in the technology industry—and in open source communities more specifically—have received a lot of coverage, both on Opensource.com and elsewhere. One approach to the issue foregrounds arguments about concepts that are more abstract—like human decency, for example.

LVFS makes Linux firmware updates easier

Monday 20th of November 2017 08:01:00 AM

Traditionally, updating a BIOS or a network card's firmware in Linux meant booting into Microsoft Windows or preparing a MS-DOS floppy disk and hoping everything would work correctly after the update. Periodically searching a vendor website for updates is a manual and error-prone task and not something we should ask users to do. A firmware update service makes it simpler for end users to implement hardware updates.

A firmware update service requires two things:

Font licensing and use: What you need to know

Monday 20th of November 2017 08:01:00 AM

Most of us have dozens of fonts installed on our computers, and countless others are available for download, but I suspect that most people, like me, use fonts unconsciously. I just open up LibreOffice or Scribus and use the defaults. Sometimes, however, we need a font for a specific purpose, and we need to decide which one is right for our project.

5 open source fonts ideal for programming

Friday 17th of November 2017 08:02:00 AM

What is the best programming font? First, you need to consider that not all fonts are created equally. When choosing a font for casual reading, the reader expects the letters to smoothly flow into one another, giving an easy and enjoyable experience. A single character for a standard font is akin to puzzle piece designed to carefully mesh with every other part of the overall typeface.

10 easy steps from proprietary to open source

Why is collaboration so difficult?

Thursday 16th of November 2017 08:00:00 AM

Many contemporary definitions of "collaboration" define it simply as "working together"—and, in part, it is working together. But too often, we tend to use the term "collaboration" interchangeably with cognate terms like "cooperation" and "coordination." These terms also refer to some manner of "working together," yet there are subtle but important differences between them all.

How to create better documentation with a kanban board

Wednesday 15th of November 2017 11:45:00 AM

If you're working on documentation, a website, or other user-facing content, it's helpful to know what users expect to find—both the information they want and how the information is organized and structured. After all, great content isn't very useful if people can't find what they're looking for.

Security: Uber Sued, Intel ‘Damage Control’, ZDNet FUD, and XFRM Privilege Escalation

  • Uber hit with 2 lawsuits over gigantic 2016 data breach
    In the 48 hours since the explosive revelations that Uber sustained a massive data breach in 2016, two separate proposed class-action lawsuits have been filed in different federal courts across California. The cases allege substantial negligence on Uber’s part: plaintiffs say the company failed to keep safe the data of the affected 50 million customers and 7 million drivers. Uber reportedly paid $100,000 to delete the stolen data and keep news of the breach quiet. On Tuesday, CEO Dara Khosrowshahi wrote: “None of this should have happened, and I will not make excuses for it.”
  • Intel Releases Linux-Compatible Tool For Confirming ME Vulnerabilities [Ed: ‘Damage control’ strategy is to make it look like just a bug.]
    While Intel ME security issues have been talked about for months, confirming fears that have been present about it for years, this week Intel published the SA-00086 security advisory following their own internal review of ME/TXE/SPS components. The impact is someone could crash or cause instability issues, load and execute arbitrary code outside the visibility of the user and operating system, and other possible issues.
