One of the great things about open source is that you're free to modify and redistribute it in whichever way you like. This is real creative freedom that I support. All of my apps and games are open source. A while back, I helped fund the opening of some game music and art assets to the public. Being in the public domain (or having a Creative Commons license, as these art assets now do) allows for public remixing and free use of the content. Gotta love that. read more

What became of the crowdfunded projects we covered in 2014? Two earned more than $2 million each, about a third went unfunded, and half had shipping delays. Ten years ago if somebody were to tell you you’d soon be able to collect thousands and even millions of dollars for your product idea simply by posting a summary and some pictures on a web page, you might have been inclined to check their meds. Then Kickstarter launched in 2009, and small-scale investing changed forever.

NixOS 14.12 'Caterpillar' has been released, the third stable release branch. In addition to numerous new and upgraded packages, this release has the following highlights: systemd has been updated to version 217, which has numerous improvements; Nix has been updated to 1.8; NixOS is now based on glibc 2.20; KDE has been updated to 4.14; the default Linux kernel has been updated to 3.14. If users.mutableUsers is enabled (the default), changes made to the declaration of a user or group will be correctly realised when running nixos-rebuild. For instance, removing a user specification from configuration.nix will cause the actual user account to be deleted. If users.mutableUsers is disabled, it is no longer necessary to specify UIDs or GIDs.

Mark Shuttleworth reflects on security issues of 2014 and the 10 years that Ubuntu Linux has existed

I've been a fan of Free Software for quite some time, but for the most part I've found my opinions lean in the more pragmatic Bruce Perens Open Source camp. I value free software ideals but also accept other Open Source licenses that may not meet the strict definition of Free Software. I also don't refer to it as GNU/Linux.

In today's open source roundup: Chromebooks can now run Linux in a window. Plus: NixOS 14.12 "Caterpillar" released, and Google Keep for Android versus Evernote.

If you read my post on GDB, you know how important and useful a debugger I think can be for a C/C++ program. However, if a command line debugger like GDB sounds more like a problem than a solution to you, you might be more interested in Nemiver. Nemiver is a GTK+-based standalone graphical debugger.

What an outstanding year for open source and the Opensource.com community! We shared more than 800 stories on how the open source way is changing our world and pushing innovation to new limits.
