    Linux comes with lots of tools, but the community gravitates to a much smaller constellation of preferred applications. For word processing, most users turn to LibreOffice, although several other word processing tools populate the repositories of the top Linux distros. For a web browser, most users turn to Firefox or Chrome. Gimp is the king of raster (bitmap) graphics tools for the Linux space, with Krita as a leading alternative, but is there more to the story? And shouldn't we, reporters and chroniclers of the Linux space, reach wider across the landscape to bring you the alternatives? This month, we take a look at Pixelitor, a free graphics editor that might not be as multi-featured as Gimp, but that's good news for users who have a more minimalist bent.

    If you enjoy writing and editing words, there are many, many different options that can help you do the job. But if you enjoy writing and editing music, there aren't that many options at all. And if writing music should involve ledger lines, semibreves, and demisemihemidemisemiquavers, there are even fewer options. There's LilyPond, which is both a standalone notation editor and part of the Rosegarden MIDI sequencer, and there's this, MuseScore, a more ambitious attempt to unseat behemoth proprietary applications like Sibelius and Finale. MuseScore v3.0 is a milestone release and the result of almost four years work by its developers and community. And since MusicScore is open source, it's the community that really sets this application apart, because there's a huge online library of user-submitted and commercial scores that you can access with an account and download directly into the application, without shedding a single tear of inspiration. There are hundreds of high quality scores you can download, from Bach to bagpipes, with licenses varying from personal use to commercial modification, and opening a downloaded score is one of the best reasons to install MuseScore.

Raspberry Pi 3 Model B+ First Impressions

I have always been curious about the tiny computer called Raspberry Pi but I didn’t have the time or opportunity to buy one until now. I got the latest version (Raspberry Pi 3 Model B+) along with bundled accessories from AliExpress for $65. I think it was a good deal considering what I got which I will explain to you later on. But before that and for your convenience, here are some quick facts about Raspberry Pi that I got from Wikipedia... Read more

GNOME Desktop: Parental Controls and More

  • Parental controls & metered data hackfest: days 1 & 2
    I’m currently at the Parental Controls & Metered Data hackfest at Red Hat’s office in London. A bunch of GNOME people from various companies (Canonical, Endless, elementary, and Red Hat) have gathered to work out a plan to start implementing these two features in GNOME. The first two days have been dedicated to the parental control features. This is the ability for parents to control what children can do on the computer. For example, locking down access to certain applications or websites. Day one began with presentations of the Endless OS implementation by Philip, followed by a demonstration of the Elementary version by Cassidy. Elementary were interested in potentially expanding this feature set to include something like Digital Wellbeing – we explored the distinction between this and parental controls. It turns out that these features are relatively similar – the main differences are whether you are applying restrictions to yourself or to someone else, and whether you have the ability to lift/ignore the restrictions. We’ve started talking about the latter of these as “speed bumps”: you can always undo your own restrictions, so the interventions from the OS should be intended to nudge you towards the right behaviour. After that we looked at some prior art (Android, iOS), and started to take the large list of potential features (in the image above) down to the ones we thought might be feasible to implement. Throughout all of this, one topic we kept coming back to was app lockdown. It’s reasonably simple to see how this could be applied to containerised apps (e.g. Snap or Flatpak), but system applications that come from a deb or an rpm are much more difficult. It would probably be possible – but still difficult – to use an LSM like AppArmor or SELinux to do this by denying execute access to the application’s binary. One obvious problem with that is that GNOME doesn’t require one of these and different distributions have made different choices here… Another tricky topic is how to implement website white/blacklisting in a robust way. We discussed using DNS (systemd-resolved?) and ip/nftables implementations, but it might turn out that the most feasible way is to use a browser extension for this.
  • GNOME ED Update – February
    Another update is now due from what we’ve been doing at the Foundation, and we’ve been busy! As you may have seen, we’ve hired three excellent people over the past couple of months. Kristi Progri has joined us as Program Coordinator, Bartłomiej Piorski as a devops sysadmin, and Emmanuele Bassi as our GTK Core developer. I hope to announce another new hire soon, so watch this space… There’s been quite a lot of discussion around the Google API access, and GNOME Online Accounts. The latest update is that I submitted the application to Google to get GOA verified, and we’ve got a couple of things we’re working through to get this sorted.
