Today we celebrate 20 years since the first release of Qt was uploaded to sunsite.unc.edu and announced, six days later, at comp.os.linux.announce. Over these years, Qt evolved from a two person Norwegian project to a full-fledged, social-technical world-wide organism that underpins free software projects, profitable companies, universities, government-related organizations, and more. It's been an exciting journey.

Fred Trotter is easy to recognize; he's a tall man with an equally big presence. Whether he's sporting his signature wild shock of blond hair or has shaved it bald as he does once a year or so, he can't be missed in a crowd. Any place where open source, big data, and healthcare-oriented people are gathered, you are likely to find him and his crew. read more

OpenStack Summit is happening right now in Vancouver. Kavit Munshi, an OpenStack Ambassador based in India, is there, and if I had to guess, he's helped more than a handful of users, face to face, with their problems and questions by now. read more

Working directly with hardware is hard. Each project brings with it mundane questions of which compiler to use, what communications protocols to work with, and how to load code. Developers also need to figure out how to debug the live system without affecting the program being executed. In the past this has required expensive and proprietary software, but thanks to commodity hardware and projects such as OpenOCD, developing programs that run directly on embedded hardware is easier than ever before. read more

FlightGear is this world's most advanced open source flight simulation project with a thriving community of users and contributors around it. These contributors are passionate people that love aviation (some are former pilots), or airspace engineering, or just like having fun with 3D modelling. This has the gorgeous result of having over 450 aircrafts in the official online FlightGear hangar!

The open hardware movement, much like the open source movement as a whole, is constantly growing and changing. To celebrate our open hardware series—and to help keep you in the loop on all things open hardware—we've rounded up 21 makers, tinkerers, and open hardware enthusiasts to follow on Twitter. Want more? Check out @opensourceway's full open hardware list. read more

At the start of 2014, attackers' favorite distributed denial of service attack strategy was to send messages to misconfigured servers with a spoofed return address - the servers would keep trying to reply to those messages, allowing the attackers to magnify the impact of their traffic.

Paranoia over NSA tampering spurs de-Westernisation drive Russia's Minister of Communications and Mass Media, Nikolai Nikiforov, has taken part in talks to form a consortium that will aid Russia in developing a custom mobile OS, reportedly a forked version of Jolla's Sailfish OS, to lessen its dependence on Western technology.…

The OpenStack Infrastructure team manages all the services that developers in the OpenStack project interface with on a day-to-day basis, including the code review and continuous integration system, Wiki, IRC bots, and mailing lists. We are also an open source project in our own right. All of the code and configurations used in our infrastructure is available in a series of public code repositories and all of our documentation is publicly available. This is in contrast to many other open source projects that either rely upon proprietary resources provided by a code hosting service, such as SourceForge or GitHub, or have a company with an IT staff that manages an infrastructure, like the Ubuntu project. read more

There are many ways to convert a video file on a Linux system, but using a tool with a graphical user interface is imperative for those who want to do it easily and in a more user friendly way. Thankfully, there are many open source GUI tools that could do the job just fine and you can find some specialization here and there if you look closely.

I spend a lot of time at conferences and events like Maker Faires, and having co-authored a book on the Raspberry Pi, I spend a lot of time talking to people about things like small electronics and open hardware. Probably the most frequent question I hear is, "Should I get a Raspberry Pi or an Arduino?" read more
