Frogr 1.2 released

Of course, just a few hours after releasing frogr 1.1, I’ve noticed that there was actually no good reason to depend on gettext 0.19.8 for the purposes of removing the intltool dependency only, since 0.19.7 would be enough.

So, as raising that requirement up to 0.19.8 was causing trouble to package frogr for some distros still in 0.19.7 (e.g. Ubuntu 16.04 LTS), I’ve decided to do a quick new release and frogr 1.2 is now out with that only change.

One direct consequence is that you can now install the packages for Ubuntu from my PPA if you have Ubuntu Xenial 16.04 LTS or newer, instead of having to wait for Ubuntu Yakkety Yak (yet to be released). Other than that 1.2 is exactly the same than 1.1, so you probably don’t want to package it for your distro if you already did it for 1.1 without trouble. Sorry for the noise.


Frogr 1.1 released

After almost one year, I’ve finally released another small iteration of frogr with a few updates and improvements.

Screenshot of frogr 1.1

Not many things, to be honest, bust just a few as I said:

  • Added support for flatpak: it’s now possible to authenticate frogr from inside the sandbox, as well as open pictures/videos in the appropriate viewer, thanks to the OpenURI portal.
  • Updated translations: as it was noted in the past when I released 1.0, several translations were left out incomplete back then. Hopefully the new version will be much better in that regard.
  • Dropped the build dependency on intltool (requires gettext >= 0.19.8).
  • A few bugfixes too and other maintenance tasks, as usual.

Besides, another significant difference compared to previous releases is related to the way I’m distributing it: in the past, if you used Ubuntu, you could configure my PPA and install it from there even in fairly old versions of the distro. However, this time that’s only possible if you have Ubuntu 16.10 “Yakkety Yak”, as that’s the one that ships gettext >= 0.19.8, which is required now that I removed all trace of intltool (more info in this post).

However, this is also the first time I’m using flatpak to distribute frogr so, regardless of which distribution you have, you can now install and run it as long as you have the org.gnome.Platform/x86_64/3.22 stable runtime installed locally. Not too bad! :-). See more detailed instructions in its web site.

That said, it’s interesting that you also have the portal frontend service and a backend implementation, so that you can authorize your flickr account using the browser outside the sandbox, via the OpenURI portal. If you don’t have that at hand, you can still used the sandboxed version of frogr, but you’d need to copy your configuration files from a non-sandboxed frogr (under ~/.config/frogr) first, right into ~/.var/app/org.gnome.Frogr/config, and then it should be usable again (opening files in external viewers would not work yet, though!).

So this is all, hope it works well and it’s helpful to you. I’ve just finished uploading a few hundreds of pictures a couple of days ago and it seemed to work fine, but you never know… devil is in the detail!


Chromium Browser on xdg-app

Last week I had the chance to attend for 3 days the GNOME Software Hackfest, organized by Richard Hughes and hosted at the brand new Red Hat’s London office.

And besides meeting new people and some old friends (which I admit to be one of my favourite aspects about attending these kind of events), and discovering what it’s now my new favourite place for fast-food near London bridge, I happened to learn quite a few new things while working on my particular personal quest: getting Chromium browser to run as an xdg-app.

While this might not seem to be an immediate need for Endless right now (we currently ship a Chromium-based browser as part of our OSTree based system), this was definitely something worth exploring as we are now implementing the next version of our App Center (which will be based on GNOME Software and xdg-app). Chromium updates very frequently with fixes and new features, and so being able to update it separately and more quickly than the OS is very valuable.

So, while Joaquim and Rob were working on the GNOME Software related bits and discussing aspects related to Continuous Integration with the rest of the crowd, I spent some time learning about xdg-app and trying to get Chromium to build that way which, unsurprisingly, was not an easy task.

Fortunately, the base documentation about xdg-app together with Alex Larsson’s blog post series about this topic (which I wholeheartedly recommend reading) and some experimentation from my side was enough to get started with the whole thing, and I was quickly on my way to fixing build issues, adding missing deps and the like.

Note that my goal at this time was not to get a fully featured Chromium browser running, but to get something running based on the version that we use use in Endless (Chromium 48.0.2564.82), with a couple of things disabled for now (e.g. chromium’s own sandbox, udev integration…) and putting, of course, some holes in the xdg-app configuration so that Chromium can access the system’s parts that are needed for it to function (e.g. network, X11, shared memory, pulseaudio…).

Of course, the long term goal is to close as many of those holes as possible using Portals instead, as well as not giving up on Chromium’s own sandbox right away (some work will be needed here, since `setuid` binaries are a no-go in xdg-app’s world), but for the time being I’m pretty satisfied (and kind of surprised, even) that I managed to get the whole beast built and running after 4 days of work since I started :-).

But, as Alberto usually says… “screencast or it didn’t happen!”, so I recorded a video yesterday to properly share my excitement with the world. Here you have it:

[VIDEO: Chromium Browser running as an xdg-app]

As mentioned above, this is work-in-progress stuff, so please hold your horses and manage your expectations wisely. It’s not quite there yet in terms of what I’d like to see, but definitely a step forward in the right direction, and something I hope will be useful not only for us, but for the entire Linux community as a whole. Should you were curious about the current status of the whole thing, feel free to check the relevant files at its git repository here.

Last, I would like to finish this blog post saying thanks specially to Richard Hughes for organizing this event, as well as the GNOME Foundation and Red Hat for their support in the development of GNOME Software and xdg-app. Finally, I’d also like to thank my employer Endless for supporting me to attend this hackfest. It’s been a terrific week indeed… thank you all!

Frogr 1.0 released

I’ve just released frogr 1.0. I can’t believe it took me 6 years to move from the 0.x series to the 1.0 release, but here it is finally. For good or bad.

Screenshot of frogr 1.0This release is again a small increment on top of the previous one that fixes a few bugs, should make the UI look a bit more consistent and “modern”, and includes some cleanups at the code level that I’ve been wanting to do for some time, like using G_DECLARE_FINAL_TYPE, which helped me get rid of ~1.7K LoC.

Last, I’ve created a few packages for Ubuntu in my PPA that you can use now already if you’re in Vivid or later while it does not get packaged by the distro itself, although I’d expect it to be eventually available via the usual means in different distros, hopefully soon. For extra information, just take a look to frogr’s website at

Now remember to take lots of pictures so that you can upload them with frogr 🙂

Happy new year!

Importing include paths in Eclipse

First of all, let me be clear: no, I’m not trying to leave Emacs again, already got over that stage. Emacs is and will be my main editor for the foreseeable future, as it’s clear to me that there’s no other editor I feel more comfortable with, which is why I spent some time cleaning up my .emacs.d and making it more “manageable”.

But as much as like Emacs as my main “weapon”, I sometimes appreciate the advantages of using a different kind of beast for specific purposes. And, believe me or not, in the past 2 years I learned to love Eclipse/CDT as the best work-mate I know when I need some extra help to get deep inside of the two monster C++ projects that WebKit and Chromium are. And yes, I know Eclipse is resource hungry, slow, bloated… and whatnot; but I’m lucky enough to have fast SSDs and lots of RAM in my laptop & desktop machines, so that’s not really a big concern anymore for me (even though I reckon that indexing chromium in the laptop takes “quite some time”), so let’s move on 🙂

However, there’s this one little thing that still bothers quite me a lot of Eclipse: you need to manually setup the include paths for the external dependencies not in a standard location that a C/C++ project uses, so that you can get certain features properly working such as code auto-completion, automatic error-checking features, call hierarchies… and so forth.

And yes, I know there is an Eclipse plugin adding support for pkg-config which should do the job quite well. But for some reason I can’t get it to work with Eclipse Mars, even though others apparently can use it there for some reason (and I remember using it with Eclipse Juno, so it’s definitely not a myth).

Anyway, I did not feel like fighting with that (broken?) plugin, and in the other hand I was actually quite inclined to play a bit with Python so… my quick and dirty solution to get over this problem was to write a small script that takes a list of package names (as you would pass them to pkg-config) and generates the XML content that you can use to import in Eclipse. And surprisingly, that worked quite well for me, so I’m sharing it here in case someone else finds it useful.

Using frogr as an example, I generate the XML file for Eclipse doing this:

  $ pkg-config-to-eclipse glib-2.0 libsoup-2.4 libexif libxml-2.0 \
        json-glib-1.0 gtk+-3.0 gstreamer-1.0 > frogr-eclipse.xml

…and then I simply import frogr-eclipse.xml from the project’s properties, inside the C/C++ General > Paths and Symbols section.

After doing that I get rid of all the brokenness caused by so many missing symbols and header files, I get code auto-completion nicely working back again and all those perks you would expect from this little big IDE. And all that without having to go through the pain of defining all of them one by one from the settings dialog, thank goodness!

Now you can quickly see how it works in the video below:

This has been very helpful for me, hope it will be helpful to someone else too!

GStreamer Hackfest 2015

Last weekend I visited my former office in (lovely) Staines-upon-Thames (UK) to attend the GStreamer hackfest 2015, along with other ~30 hackers from all over the world.

This was my very first GStreamer hackfest ever and it was definitely a great experience, although at the beginning I was really not convinced to attend since, after all, why bother attending an event about something I have no clue about?

But the answer turned out to be easy in the end, once I actually thought a bit about it: it would be a good opportunity both to learn more about the project and to meet people in real life (old friends included), making the most of it happening 15min away from my house. So, I went there.

And in the end it was a quite productive and useful weekend: I might not be an expert by now, but at least I broke the barrier of getting started with the project, which is already a good thing.

And even better, I managed to move forward a patch to fix a bug in PulseAudio I found on last December while fixing an downstream issue as part of my job at Endless. Back then, I did not have the time nor the knowledge to write a proper patch that could really go upstream, so I focused on fixing the problem at hand in our platform. But I always felt the need to sit down and cook a proper patch, and this event proved to be the perfect time and place to do that.

Now, thanks to the hackfest (and to Arun Raghavan in particular, thanks!), I’m quite happy to see that the right patch might be on its way to be applied upstream. Could not be happier about it! 🙂

Last, I’d like to thank to Samsung’s OSG, and specially to Luis, for having done a cracking job on making sure that everything would run smoothly from beginning to end. Thanks!

Frogr 0.11 released

Screenshot of Frogr 0.11

So, after neglecting my responsibilities with this project for way too long, I finally released frogr 0.11 now, making the most that I’m now enjoying some kind of “parenting vacation” for a few days.

Still, do not expect this new release to be fully loaded of new features and vast improvements, as it’s more like another incremental update that adds a couple of nice new things and fixes a bunch of problems I was really unhappy about (e.g. general slowness, crashes).

Wrapping it up, the main changes included with this release are:

  • Moved to the new GTK+’s header bar plus the typical menu button when GTK+ >= 3.12 (GTK+ 3.4 is still supported). I personally like this change a lot, as it makes frogr much more compact and sleek IMHO, and much better integrated with newer releases of GNOME.
  • Added a new option to automatically replace the “date posted” field in flickr with the “date taken” value from the EXIF metadata when uploading pictures. Useful to keep your photo stream sorted regardless of when you uploaded which pictures. Thanks a lot to Luc Pionchon for requesting this feature. I never thought of it before, now I use it all the time!
  • Sped up the load of pictures into the main window, as it was a very slow process when importing tags from the XMP keywords was enabled. I measured a 3x improvement, but YMMV.
  • Fixed random crashes due to the missing initialization of the gcrypt library introduced with the recent changes to use SSL API end points. Thanks a lot Andrés for your help with this!
  • Fixed issues related to the OS X port, which prevented frogr 0.9 from having video support and caused many problems with the 0.10 release. Now it should be fine, grab the bundle from here.
  • Other things: removed calls to deprecated APIs, updated translations, fixed a few minor bugs and a bit of a clean-up here and there, which is usually good.

As usual, feel free to check the website of the project in case you want to know more about frogrhow to get it or how to contribute to it. I’m having a hard time lately to find time to devote to this pet project, so any help anyone can provide will be more than welcome 🙂 fosdem-15-logo

By the way, I’m going to FOSDEM this year again, so feel free to say “hi” if you want to chat and/or share a beer (or more!).

Endless changes ahead!

I know I haven’t blogged for a while, and definitely not as much as I would like, but that was partially because I was quite busy during my last days in Samsung (left on the 25th of July), where I wanted to make sure I did not leave any loose end before departure, and that everything was properly handed over to the right people there.

But that was one month ago… so what did I do since then? Many many things, and most of them away from a keyboard, at least until the past week. Main highlights:

  • One week travelling by car with my family all the way down to Spain from the UK, through France, visiting all the nice places we could (and could afford) in the way, which was a lot of fun and an incredible experience.
  • The goal of taking the car to Spain was to sell it once we were there and, surprisingly enough, we did it in record time, so one thing less to worry about…
  • 2 weeks in Spain having proper “relaxing holidays” to get some quality time off in between the two jobs, to properly recharge batteries. Not that the previous week was not holidays, but travelling 2200 km by car with two young kids on the back can be amazing and exhausting at the same time 🙂
  • 1 week in the UK to make sure I had everything ready by the time I officially started in the new company, where I will initially be working from home: assemble a home office in my spare bedroom, and prepare my new laptop mainly. In the end, we (my wife helped me a lot) finished by Wednesday, so on Thursday we went for a last 2-day getaway to Wales (what a beautiful place!) by car, making the most that we were kids-free.

Endless Mobile logoTherefore, as you can imagine, I didn’t have much time for blogging lately, but still I would like to share with the world my “change of affiliation” so here it is: since yesterday I’m officially part of the amazing team at Endless, an awesome start up from San Francisco committed to break the digital divide in the developing world by taking GNOME-based technology to the end users in ways that were not imaginable before. And I have to say that’s a vision I fell in love with since the very first time I heard about it (last year in Brno, during Matt’s keynote at GUADEC).

But just in case that was not awesome enough by itself, the other thing that made me fall in love with the company was precisely the team they have assembled, because even if I’m mostly a technical guy, I still value a lot the human side of the places I work in. And in this regard Endless seems to be perfect, or even better!

So, I’m extremely happy these days because of this new challenge I’m seeing in front of me, and because of the opportunity I’m being given to have a real positive impact in the lives of millions of people who still can’t access to technology as they should be able to do it. Also, I feel blessed and privileged for having been given the chance to be part of such an amazing team of people. Could not be happier at this time! 🙂

Last to finish this post, I would like to say thanks to my friend Joaquim, since he was who introduced me to Matt in the first place and “created” this opportunity for me. Thank you!

Frogr 0.10 released

frogrQuick post to let the world know that I’ve just released a new version of frogr right now, in order to address a few issues present in the previous version. Mainly:

  • Deprecation of non-SSL end points for the Flickr API (see these two posts for more info). From now on, frogr will use SSL-only API calls.
  • Address issues with frogr‘s AppData file. Apparently, the AppData file was neither valid (according to appdata-validate) nor being installed properly, preventing frogr from showing up nicely in the GNOME Software app.
  • Allow disabling video uploads at configuration time (enabled by default), instead of making the decision depending on the detected platform. This will hopefully make life easier for packagers of other platforms (e.g. MacPorts).
  • Removed libsoup-gnome code once and for all (API deprecated a while ago).
  • Other things: updated translations and fixed a few minor bugs.

As usual, feel free to check the website of the project in case you want to know more about frogrhow to get it or how to contribute to it.

Frogr 0.9 released

So, after a bit more than one year without releasing any version of frogr, I finally managed to get some “spare” time to put all the pieces together and ship the ninth version of it, which I believe/hope is going to be a quite solid one.

Frogr 0.9

In all honesty, though, this version does not come with many new features as the previous ones, yet some changes and fixes that I believe were quite necessary, and therefore should help improving the user experience in some subtle ways.

For instance, the layout of the dialog to edit the details of a picture has changed (as per Ana Rey‘s comments during GUADEC) to enable a more efficient usage of vertical space, so much needed these days in small widescreen laptops. Of course, design-wise still sucks, but I believe it’s much more convenient now from a pragmatical point of view.

Also, frogr is now a little bit more “modern” in things such as that it now supports GStreamer 1.0 (0.10 still supported), a lot of deprecated code (e.g. Stock items, GtkActions) has been replaced internally and it now integrates better with GNOME Shell’s search box. Ah! and it also now provides an AppData file to integrate with GNOME Software Center, which is a nice touch too.

Another interesting thing is that I finally fixed the problem that we have with multiple selections in the main view, which was neither intuitive nor very useful, as Ctrl and Shift modifiers did not work as expected. So, from now on, it is finally possible to work with disjoint multiple selections of pictures, a feature I was missing so much.

Last, I fixed two important problems in the code that caused frogr consume two much memory, specially after uploading pictures. It was a quite severe problem since frogr was not properly freeing the memory used by pictures even after those were uploaded and removed from the UI, causing important issues in cases where people tried to upload a lot of pictures at once. It’s hopefully fixed now.

And that’s all I think. As usual, you can check the website of the project to know how to install frogr on your system if you don’t want to wait for your favourite distribution to ship it, or if you just want to check more information about the project or to contribute to it.


Ah! By the way… I’m going to FOSDEM again this year, but this time by train. Can’t wait to be there! 🙂
