Tuesday 16th of August 2016 07:03:00 AM

During the summer of 2012, Eric Rescorla and I decided to start a Certificate Authority (CA). A CA acts as a third-party to issue digital certificates, which certify public keys for certificate holders.

How to design your project for participation

Tuesday 16th of August 2016 07:00:00 AM

Working openly means designing for participation. "Designing for participation" is a way of providing people with insight into your project, which you've built from the start to incorporate and act on that insight. Documenting how you intend to make decisions, which communication channels you’ll use, and how people can get in touch with you are the first steps in designing for participation.

Flatpak: A new framework for building and distributing desktop applications

Monday 15th of August 2016 07:03:00 AM

Fragmentation is a longstanding Achilles heel for the Linux desktop. In a world of myriad incompatible distributions, popular apps are typically limited to one or two of the most popular distributions, and the creation of new apps is stifled. The impact of fragmentation on application developers offers a good example of the problem: To release an app for Linux, a developer must contend with different package formats and a baffling number of distributions, all of which have their own particular conventions.

runC: The little container engine that could

Monday 15th of August 2016 07:02:00 AM

runC, a lightweight universal container runtime, is a command-line tool for spawning and running containers according to the Open Container Initiative (OCI) specification. That's the short version. The long version: The governance umbrella created by Docker, Google, IBM, Microsoft, Red Hat, and many other partners to create a common and standardized runtime specification has a readable spec document for the runtime elements of a container, and a usable implementation based on code contributed to the OCI by Docker.

Trends in corporate open source engagement

Friday 12th of August 2016 07:02:00 AM

In 1998, I was part of SGI when we started moving to open source and open standards, after having been a long-time proprietary company. Since then, other companies also have moved rapidly to working with open source, and the use and adoption of open source technologies has skyrocketed over the past few years. Today company involvement in open source technologies is fairly mature and can be seen in the following trends:

What is copyleft?

Friday 12th of August 2016 07:00:00 AM

If you've spent much time in open source projects, you have probably seen the term "copyleft" used. While the term is quite commonly used, many people don't understand it. Software licensing is the subject of at least as much heated debate as text editors or packaging formats. An expert understanding of copyleft would fill many books, but this article can be a starting point on your road to copyleft enlightenment.

Which type of open source license do you prefer?

Friday 12th of August 2016 06:59:00 AM

It's the age-old debate among open source enthusiasts—both developers and users alike: Which license to choose? For developers, the decision revolves around what kind of control they are willing to release to anyone wanting to modify the developer's code. For the user, the question is more about philosophy.

GPL enforcement action in Hellwig v. VMware dismissed, with an appeal expected

Thursday 11th of August 2016 06:35:00 PM

A decision in the GPL enforcement case in Germany between Christoph Hellwig (supported by the Software Freedom Conservancy) and VMware recently became public.

  • Report: If DOD Doesn't Embrace Open Source, It'll 'Be Left Behind'
    Unless the Defense Department and its military components levy increased importance on software development, they risk losing military technical superiority, according to a new report from the Center for a New American Security. In the report, the Washington, D.C.-based bipartisan think tank argues the Pentagon, which for years has relied heavily on proprietary software systems, “must actively embrace open source software” and buck the status quo. Currently, DOD uses open source software “infrequently and on an ad hoc basis,” unlike tech companies like Google, Amazon and Facebook that wouldn’t exist without open source software.
  • The Honey Trap of Copy/Pasting Open Source Code
    I couldn’t agree more with Bill Sourour’s article ‘Copy.Paste.Code?’ which says that copying and pasting code snippets from sources like Google and StackOverflow is fine as long as you understand how they work. However, the same logic can’t be applied to open source code. When I started open source coding at the tender age of fourteen, I was none the wiser to the pitfalls of copy/pasting open source code. I took it for granted that if a particular snippet performed my desired function, I could just insert it into my code, revelling in the fact that I'd just gotten one step closer to getting my software up and running. Yet, since then, through much trial and error, I’ve learned a thing or two about how to use open source code effectively.
  • Affordable, Open Source, 3D Printable CNC Machine is Now on Kickstarter
    The appeals of Kickstarter campaigns are many. There are the rewards for backers, frequently taking the form of either deep discounts on the final product or unusual items that can’t be found anywhere else. Pledging to support any crowdfunding campaign is a gamble, but it’s an exciting gamble; just browsing Kickstarter is pretty exciting, in fact, especially in the technological categories. Inventive individuals and startups offer new twists on machines like 3D printers and CNC machines – often for much less cost than others on the market.
  • Open Standards and Open Source
    Much has changed in the telecommunications industry in the years since Standards Development Organization (SDOs) such as 3GPP, ITU and OMA were formed. In the early days of telecom and the Internet, as fundamental technology was being invented, it was imperative for the growth of the new markets that standards were established prior to large-scale deployment of technology and related services. The process for development of these standards followed a traditional "waterfall" approach, which helped to harmonize (sometimes competing) pre-standard technical solutions to market needs.

  • The Voicemail Scammers Never Got Past Our OpenBSD Greylisting
    We usually don't see much of the scammy spam and malware. But that one time we went looking for them, we found a campaign where our OpenBSD greylisting setup was 100% effective in stopping the miscreants' messages. During August 23rd to August 24th 2016, a spam campaign was executed with what appears to have been a ransomware payload. I had not noticed anything particularly unusual about the bsdly.net and friends setup that morning, but then Xavier Mertens' post at isc.sans.edu Voice Message Notifications Deliver Ransomware caught my attention in the tweetstream, and I decided to have a look.
