  • 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.

TenFourFox FPR16b1 available

FPR16 got delayed because I really tried very hard to make some progress on our two biggest JavaScript deficiencies, the infamous issues 521 (async and await) and 533 (this is undefined). Unfortunately, not only did I make little progress on either, but the speculative fix I tried for issue 533 turned out to be the patch that unsettled the optimized build and had to be backed out. There is some partial work on issue 521, though, including a fully working parser patch. The problem is plumbing this into the browser runtime which is ripe for all kinds of regressions and is not currently implemented (instead, for compatibility, async functions get turned into a bytecode of null throw null return, essentially making any call to an async function throw an exception because it wouldn't have worked in the first place). This wouldn't seem very useful except that effectively what the whole shebang does is convert a compile-time error into a runtime warning, such that other functions that previously might not have been able to load because of the error can now be parsed and hopefully run. With luck this should improve the functionality of sites using these functions even if everything still doesn't fully work, as a down payment hopefully on a future implementation. It may not be technically possible but it's a start. Read more

Leftovers: Kate, Krita, UCLA Library and RcppExamples

  • Kate - Document Preview Plugin - Maintainer Wanted!

    At the moment the Document Preview plugin that e.g. allows to preview Markdown or other documents layout-ed via embedding a matching KPart is no longer maintained. If you want to step up and keep that plugin alive and kicking, now is your chance!

  • The Sprint

    Hi -)) haven’t posted for some time, because I was busy travelling and coding for the first half of the month. From Aug 5 to Aug 9, I went to the Krita Sprint in Deventer, Netherlands. According to Boud, I was the first person to arrive. My flight took a transit via Hong Kong where some flights were affected due to natural and social factors, but fortunately mine was not one of them. Upon arrival in Amsterdam I got a ticket for the Intercity to Deventer. Railway constructions made me take a transfer via Utrecht Centraal, but that was not a problem at all: the station has escalators going both up to the hall, and down to the platforms (in China you can only go to the hall by stairs or elevator (which is often crowded after you get off)). When I got out of Deventer Station, Boud immediately recognized me (how?!). It was early in the morning, and the street’s quietness was broken by the sound of me dragging my suitcase. Boud led me through Deventer’s crooked streets and alleys to his house. For the next two days people gradually arrived. I met my main mentor Dmitry (magician!) and his tiger, Sagoskatt, which I (and many others) have mistaken for a giraffe. He was even the voice actor for Sago. He had got quite a lot of insights into the code base (according to Boud, “80%”) and solved a number of bugs in Krita (but he said he introduced a lot of bugs, ha!). Also I met David Revoy (my favourite painter!), the author of Pepper and Carrot. And Tiar, our developer who started to work full-time on Krita this year; she had always been volunteering to support other Krita users and always on the IRC and Reddit. And two of other three GSoC students for the year: Blackbeard (just as his face) and Hellozee. Sh_zam could not come and lost communications due to political issues, which was really unfortunate (eh at least now he can be connected). It is feels so good to be able to see so many people in the community – they are so nice! And it is such an experience to hack in a basement church.

  • How UCLA Library preserves rare objects with open source

    The University of California, Los Angeles, (UCLA) Library houses a collection of millions of rare and unique objects, including materials dating from 3000 BCE, that could be damaged, destroyed, or otherwise threatened if they were displayed. To make these special collections widely available while keeping them secure, the UCLA Library has been modernizing its digital repository, which was established 15 years ago on now-outdated software. [...] Watch Jen's Lightning Talk to learn more about the UCLA Library's rare collections digitization project.

  • RcppExamples 0.1.9

    The RcppExamples package provides a handful of short examples detailing by concrete working examples how to set up basic R data structures in C++. It also provides a simple example for packaging with Rcpp.
