What’s the best software under Linux to create music? We answer that & the best hardware that work together. We have something for the musician to casual hardware geek, we cover the dark art of creating music under Linux as we go inside Noah’s music studio and see what he uses.

Plus we chat with ownCloud’s Community Manager about the new features in version 9, our thoughts on Microsoft’s SQL for Linux announcement & more!

Rosegarden

Rosegarden is a music composition and editing environment based around a MIDI sequencer that features a rich understanding of music notation and includes basic support for digital audio.
Rosegarden is an easy-to-learn, attractive application that runs on Linux, ideal for composers, musicians, music students, and small studio or home recording environments.
Rosegarden’s matrix and notation editors also include rulers for graphically editing control changes, as well as for velocity and pitch bend.
Rosegarden includes synth plugin support for sample-accurate synthesis of MIDI tracks.
Rosegarden uses the DSSI architecture for synth plugins, a public standard which permits each plugin to be controlled from its own custom GUI as well as Rosegarden’s built-in plugin interface.

Hydrogen

Very user-friendly, modular, fast and intuitive graphical interface based on QT 4.
Sample-based stereo audio engine, with import of sound samples in .wav, .au and .aiff formats.
Pattern-based sequencer, with unlimited number of patterns and ability to chain patterns into a song.
Up to 192 ticks per pattern with individual level per event and variable pattern length.
Unlimited instrument tracks with volume, mute, solo, pan capabilities.

Ardour

Full DAW
An Ardour track can be of type audio or MIDI, depending on the data that the track will primarily record and play back.
No limits on number of tracks, buses, plugins, inserts, or sends.
Pick your audio interface based on your needs and budget. If your OS supports it, Ardour can use it. PCI, USB, Firewire interfaces, along with the option to use network audio too.
Non-destructive, non-linear editing with unlimited undo/redo, even across editing sessions (reload and undo your changes from last time).
All editing is in-window: no switching to piano roll or other dedicated dialogs/displays for specialized operations.
Route anything to anywhere (for more than ten years!).
Matrix-style patching/routing.
Hundreds of no-cost plugins in LV2, native VST and LADSPA formats on Linux.

Facebook launches project to open source hardware, designs for cell networks | Ars Technica

There have already been a number of efforts to bring open source software and commodity hardware to bear on providing wireless service to unserved communities. OpenBTS, an open source cellular infrastructure software project, released a fully open 3G cellular network stack in October of 2014. The OpenBTS software was used by the University of California at Berkeley’s Technology and Infrastructure for Emerging Regions (TIER) research group to _build a community cellular network in Papua, Indonesia_in 2013, with a VSAT backhaul for SMS text messaging to the rest of the world.

SQL Server on Linux Shows Microsoft’s More Flexible Side

Microsoft has made a preview of SQL Server for Linux available. The final product is expected to ship in mid

Microsoft’s former CEO claimed he “loved” this week’s news that Redmond would deliver a Linux-compatible version of its ever-popular SQL Server database.

Qubes OS 3.1 has been released!

The major new architectural feature of this release has been the introduction of
the Qubes Management
infrastructure, which is
based on the popular Salt management software.

In Qubes 3.1, this management stack makes it possible to conveniently control
system-wide Qubes configuration using centralized, declarative statements.
Declarative is the key word here: it makes creating advanced configurations
significantly simpler. (The user or administrator needs only to specify what
they want to get, rather than how they want to get it).

This has already allowed us to improve our installation wizard (firstboot) so
that it now offers the user the ability to easily select from various options to
pre-create some useful configurations, such as Whonix or USB-hosting VMs.

Personal Trainer Robot Runs Linux

Vizzy will be a personal assistant robot, designed to teach exercise routines and provide physical therapy support, while also ensuring proper exercise form and monitoring physiological responses. So, much like human personal trainers, Vizzy will encourage users to keep exercising, even when they say they are tired.

Portuguese Robotics research is poised to become a reference in the field with the creations like Vizzy, a personal training robot created in the scope of one of the Entrepreneurial Research Initiatives of the Carnegie Mellon Portugal Program.
Vizzy will be a personal assistant robot, designed to teach exercise routines and provide physical therapy support, while also ensuring proper exercise form and monitoring physiological responses. This will be accomplished with its motion detectors that, much like the technology currently present in gaming consoles, is able to read the user’s body positioning. But Vizzy will also be able to detect other responses, such as body temperature and breathing pattern to gauge the user\’s physical reaction to the routine and adjusting it accordingly. So, much like human personal trainers, Vizzy will encourage users to keep exercising, even when they say they are tired.

Vizzy is under development within the “AHA – Augmented Human Assistance” project, lead by Profs. Alexandre Bernardino (IST) and Daniel P. Siewiorek (CMU). AHA is one of the six selected proposals of the CMU Portugal Program Entrepreneurial Research Initiative in 2014.

Desktop App Pick

It provides many helpful security features such as two-factor authentication, secure deletion, checksum and hash verification and WinZip\’s, PKZip\’s and 7\’s AES256 encryption, to name a few. PeaZip is a simple, sleek feature packed archive manager I recommend for any desktop.
