Building an active community requires thoughtful planning, patience, support, and constant evangelism. Even then, any of several well-known errors can prevent a community from developing.

How to Add a Swap File On Ubuntu Linux A swap file enables an operating system (OS) to utilize hard disk space to simulate additional memory. Effectively, as the system goes on the low-memory mode, it swaps a certain section of the RAM that an idle program may be using onto the hard disk to release memory capacity for other vital programs. Subsequently, when the user returns to the swapped out program, it swaps places with another program in RAM. This intelligent mix of RAM and swap files is commonly referred to as virtual memory, and its use allows the system to run a far greater number of programs than possible using only the built-in RAM.

Recent developments in the world of open source have had far reaching impacts more so than most critics initially envisaged. For example the recent announcement that the National Aeronautics and Space Administration (NASA) is committed "... to the principles of open government" and "... (to) encouraging innovation and entrepreneurship," and thus will be releasing source code for an array of its software projects, hits home to the authors of this article. read more

The medical image community embraced open source as a standard practice back in 2000, with the adoption of the Insight Toolkit (ITK). ITK is sponsored by the US National Library of Medicine and was built as a C++ library. It is the equivalent to a usable encyclopedia of image processing algorithms. read more

After three years, RHEL 7 is now GA, but that doesn't mean RHEL users didn't benefit from features updates for RHEL 6

CentOS has upgraded a lot packages, and the post that I've wrote 1 year ago no longer works in CentOS 6.5 updated up-to-date. I did a research and it looks like this will be the first tutorial in 2014 how to install owncloud in centos with nginx, postgresql and ssl.

With concerns over online privacy at its highest since the birth of the internet, we speak exclusively to the anonymous developers behind Tails.

For many users, the command line tool “diff” on Fedora is the go-to when wanting to compare the differences between two files. However, there are also a healthy selection of graphical tools available in Fedora for comparing the differences between two and even three files. Three of the graphical diff tools available in Fedora are Meld, Kompare and Diffuse.

Open science is one way today to deliver science to societies around the world. And, it can include open education, open research, open source, and open culture. read more

Marvell has posted detailed datasheets on its previously opaque Armada 370 SoC, used in Linux-based NAS systems from Buffalo, Netgear, and Synology. Until now, datasheets and other details about the ARM-based Armada 370 system-on-chips have been available only under NDA to Marvell customers and partners. Last week, however, the chipmaker released two detailed datasheets on […]

Linux and open source have long played a major role in cars' electronics, but now Tesla is taking open-source automobiles to a whole new level — by setting free its electric car patents.

In my last few articles, I looked at several different Python modules that are useful for doing computations. But, what tools are available to help you analyze the results from those computations? Although you could do some statistical analysis, sometimes the best tool is a graphical representation of the results.

Feeling dangerous? On Tuesday 17 June, gaming dev David Braben will be answering your questions on Elite, Raspberry Pi and how software development has changed over the last 30 years.

Preparations are under way for the biggest change in the UK’s approach to computing education – but Raspberry Pi’s education expert Clive Beale reveals that the government is not putting enough money where its mouth is

'In 1991, Captain Cyborg said we'd have real life Terminators'. This was the week when a piece of software (supposedly) passed the Turing Test, giving the world all the “robot overlord” headlines they could possibly need in a slow, sunny news week.
