  • Maestral Is A New Open Source Dropbox Client For Linux And macOS

    Maestral is a new open source Dropbox client for macOS and Linux, that's currently in beta. It can be used both with and without a GUI, and it was created with the purpose of having a Dropbox client that supports folder syncing to drives which use filesystems like Btrfs, Ext3, ZFS, XFS or encrypted filesystems, which are no longer supported by Dropbox.

  • GLava – OpenGL audio spectrum visualizer for desktop windows or backgrounds

    Over the past few months, I’ve written lots of reviews of open source audio software, focusing mainly on music players. Linux has a mouthwatering array of open source multimedia tools, so I’m going to turn my attention wider afield from music players. Let’s start with some multimedia candy.

    GLava is an OpenGL audio spectrum visualizer for Linux. An audio visualizer works by extracting waveform and/or frequency information from the audio and feeds this information through some display rules, which produces what you see on the screen. The imagery is usually generated and rendered in real time and in a way synchronized with the music as it is played.

    GLava makes a real-time audio visualizer appear as if it’s embedded in your desktop background, or in a window. When displayed as the background, it’ll display on top of your wallpaper, giving the appearance of a live, animated wallpaper.

    GLava is a simple C program that sets up the necessary OpenGL and Xlib code for sets of 2D fragment shaders. The software uses PulseAudio to sync the desktop visualizer with any music source.

  • Millan Castro: GSoC: First month working in Pitivi

    Pitivi is a video editor, free and open source. Targeted at newcomers and professional users, it is minimalist and powerful. This summer I am fortunate to collaborate in Pitivi development through Google Summer of Code.

    My goal is to implement an interval time system, with the support of Mathieu Duponchell, my menthor, and other members of the Pitivi community.

    An interval time system is a common tool in many video editors. It will introduce new features in Pitivi. The user will be able to set up a range of time in the timeline editor, playback specific parts of the timeline, export the selected parts of the timeline, cut or copy clips inside the interval and zoom in/out the interval.

    Mi proposal also includes the design of a marker system to store information at a certain time position.

  • Linux super-duper admin tools: health-check

    Health-check is a very useful, practical tool. It does not replace strace or netstat or perf, but it can sure help you get a very accurate multi-dimensional snapshot of whatever you're profiling. This is a very good first step that can point you in the right direction. You can then select a utility that specifically examines the relevant facet of the software run (maybe Wireshark for network or Valgrind for memory). In a way, this makes health-check into a Jack o' All Trades.

    You do need some understanding of how Linux systems work - and the application you're running. But even if you don't have that knowledge, health-check can be used for comparative studies and troubleshooting of performance bottlenecks. If you know something isn't running quite as well as it should, you can trace it once on a good system, once on a bad (affected) system, and then compare the two. The many types of data that health-check provides will greatly assist in solving the issue. And that brings us to the end of this tutorial. With some luck, you have learned something new, and it was an enjoyable ride, too. Take care.

Software: Genome Browsers, EtherCalc and Curl

  • Best Free Web Based Genome Browsers

    In the fields of molecular biology and genetics, a genome is the genetic material of an organism. It consists of DNA (or RNA in RNA viruses). Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome—more than 3 billion DNA base pairs—is contained in all cells that have a nucleus. The study of the genome is called genomics.

    In bioinformatics, a genome browser is a graphical interface for display of information from a biological database for genomic data. They are important tools for studying genomes given the vast amounts of data available. They typically load very large files, such as whole genome FASTA files and display them in a way that users can make sense of the information there. They can be used to visualize a variety of different data types.

    Genome browsers enable researchers to visualize and browse entire genomes with annotated data including gene prediction and structure, proteins, expression, regulation, variation, comparative analysis, etc. They use a visual, high-level overview of complex data in a form that can be grasped at a glance and provide the means to explore the data in increasing resolution from megabase scales down to the level of individual elements of the DNA sequence.

    There’s a wide range of web based genome browsers. We’re going to restrict our selection to the top 4.

  • Daniel Stenberg: curl 7.65.2 fixes even more

    Six weeks after our previous bug-fix release, we ship a second release in a row with nothing but bug-fixes. We call it 7.65.2. We decided to go through this full release cycle with a focus on fixing bugs (and not merge any new features) since even after 7.65.1 shipped as a bug-fix only release we still seemed to get reports indicating problems we wanted fixed once and for all.

    Download curl from curl.haxx.se as always!

    Also, I personally had a vacation already planned to happen during this period (and I did) so it worked out pretty good to take this cycle as a slightly calmer one.

    Of the numbers below, we can especially celebrate that we’ve now received code commits by more than 700 persons!

Tizonia – powerful open source cloud music player for the Linux terminal

Filed under
Software

The Linux platform has matured into an excellent way of listening to streaming music services. There are clients available for most of the popular music streaming services. But what if you want a single app that covers the very popular ones without straying away from the Linux terminal. Step forward Tizonia.

Tizonia offers access to some excellent streaming music services — all from the command line. The software supports popular services such as YouTube, Spotify, Google Play Music, SoundCloud, Chromecast, and more.

Tizonia is innovative software. It doesn’t use FFmpeg, libav, gstreamer or libvlc for playback. Instead, the software’s multimedia framework is based on OpenMAX IL 1.2. OpenMAX (Open Media Acceleration) is a non-proprietary and royalty-free cross-platform set of C-language programming interfaces. It provides abstractions for routines that are especially useful for processing of audio, video, and still images.

Tizonia is C/C++ software which integrates online services with Python connectors/proxies. This means it should be fairly easy to integrate new services, assuming a Python-based API is accessible.

LXD 3.15 has been released

Filed under
Server
Software

The LXD team is very excited to announce the release of LXD 3.15!

This release both includes a number of major new features as well as some significant internal rework of various parts of LXD.

One big highlight is the transition to the dqlite 1.0 branch which will bring us more performance and reliability, both for our cluster users and for standalone installations. This rework moves a lot of the low-level database/replication logic to dedicated C libraries and significantly reduces the amount of back and forth going on between C and Go.

On the networking front, this release features a lot of improvements, adding support for IPv4/IPv6 filtering on bridges, MAC and VLAN filtering on SR-IOV devices and much improved DHCP server management.

We’re also debuting a new version of our resources API which will now provide details on network devices and storage disks on top of extending our existing CPU, memory and GPU reporting.

And that’s all before looking into the many other performance improvements, smaller features and bugfixes that went into this release.
