Canonical has used a variety of content management systems throughout the years, including Drupal and Zope, and a large number of our websites have run on WordPress; in fact, many still do. Our developer portal was one of these standard WordPress instances, which worked well enough for a simple website that didn't get very heavy traffic, but we began to outgrow it. read more

Editing in Kdenlive is done both in the monitors and in the timeline. Your initial cuts are made while reviewing your footage and placing clips into the timeline in the order that you want your movie to be seen. Once the initial cut is done, though, most of your time will be spent in the timeline. It doesn't take long to get comfortable working in the timeline, but it does take a little bit of work to get efficient. read more

Free Electrons has posted free detailed training materials for its course on building an embedded Linux project on a BeagleBone Black SBC using Buildroot. Last November, Linux training firm Free Electrons posted free training materials for a three-day training course on building an embedded Linux project using Yocto Project and OpenEmbedded. Now, the company has […]

In Fedora 22, one of the new features from the Cloud SIG is a project called Tunir. It is a very simple system which can be used to test Fedora Cloud images, or it can be used to test any normal software project using the Cloud images or bare metal systems.

Version 2.0 to have free, open compiler and standard library. WWDC 2015 Apple will release version 2.0 of its Swift programming language as open source.

Because you're a reader of Linux Journal, you probably already know that Linux has a rich virtualization ecosystem. KVM is the de facto standard, and VirtualBox is widely used for desktop virtualization. Veterans should remember Xen (it's still in a good shape, by the way), and there is also VMware (which isn't free but runs on Linux as well).

Peppermint combines Ubuntu Linux with Google's Chromium Web browser and cloud services for a modern take on the desktop.

As the name suggest 'Very Secure File Transfer Protocol Deamon' (VSFTPD) is one of the most secure FTP daemons available, vsftpd is used as the default FTP server in the Ubuntu, CentOS, Fedora, NimbleX, Slackware and RHEL Linux distributions.

The Government of India has implemented a remarkable new policy-level change for open source software (OSS) deployment. The Ministry of Communication and Information Technology has asked that open source software-based applications be included in Requests for Proposals (RFPs) for all new procurements. Note there is not a plan at this time to replace existing proprietary systems with open source software. read more

Here's some new GCC compiler benchmarks on Linux x86_64... Some of the results are interesting and show change in GCC's performance on this Haswell-based system over the past two years.

When I started working at the Raspberry Pi Foundation, we set out to revamp the website and add learning materials for educators. In the mean time, we wanted to get a few resources out in time for Hour of Code week, so we wrote them on GitHub for easy sharing. It's easy to get started writing with markdown, and it made collaboration straightforward. read more

The disclosures, based on documents provided by Edward J. Snowden, the former N.S.A. contractor, and shared with The New York Times and ProPublica, come at a time of unprecedented cyberattacks on American financial institutions, businesses and government agencies, but also of greater scrutiny of secret legal justifications for broader government surveillance... One internal N.S.A. document notes that agency surveillance activities through “hacker signatures pull in a lot.”

Currently I work at the MIT Haystack Observatory, where I explore a number of exciting topics, including, but not limited to: high power large aperture radar measurements of the ionosphere, meteors, and planetary objects; passive radar, milliwatt class spread spectrum HF radar, megawatt class ionospheric heating, ionospheric remote sensing with global navigation satellites, and radio astronomy. I’ve published two open source projects that turn your software defined radar into a radio remote sensing instrument: the GNU Chirp Sounder, which allows you to listen to over the horizon radars and chirp ionosondes all around the world; and the GNU Ionospheric Tomography Receiver (Jitter), which allows you the determine the line integral of ionospheric electron density by listening to 150/400 MHz coherent beacons on satellites.

The Rigol DS1052E is the de facto oscilloscope for any tinkerer’s bench. It’s cheap, it’s good enough, and it’s been around for a long time; with the new 1054 zed model out now, you might even be able to pick up a 1052E on the cheap.

[wd5gnr1] came up with a really interesting piece of software that allows a Linux system to control most of the functions on this popular scope. With just a USB cable, you can read and log all the measurement of the scope, save waveforms in CSV format, and send data to gnuplot and qtiplot.
