Relatório da Hackatona de Design

Durante semana, no mês de janeiro, eu estive no Brasil, no Rio de Janeiro para uma hackatona de design, com os designers de Endless e do projeto GNOME.

Que é o produto de Endless?

O maior produto de Endless é um sistema operativo para mini computadores que eles fazem, o Endless Mini e o Endless (Maxi?). O sistema operativo usa Linux e uma versão de GNOME com algumas changes (mudanças). O uso principal desses computadores é de ter muitas informações sem acesso à Internet. Por exemplo, tem muitos aplicativos sobre viagens, animais e etc que são diretamente dentro do computador, usando Wikipedia como fonte, e uma outra aplicação de receitas, com uma outra terceira fonte.

A hackatona em si

Os dois primeiros dias foram para viajar e visitar os usuários “beta” do Endless computadores, um dia na Rocinha, uma favela do Rio. E um outro dia em Magé, uma cidade rural do estado do Rio.
Os três últimos dias foram para discussões no escritório de Endless.

Observações

É uma coisa para fazer testes de usabilidade nos EUA e na Europa, e uma outra coisa de fazer isso num país sem habitude de usar “computadores pessoais” com Windows o MacOS X, mas muita mais habitude com celulares.

Por exemplo:
- Se se tem um mouse, vão dar dublo clique. Não é um problema com teclados sensíveis.
- Dividir a tela para ter um aplicativo ao lado de uma outra é difícil também.
- Se não se tem um acesso à Internet, não vão tentar instalar o acessar outros aplicativos que estão já no computador.
- Não estão acostumados a fechar aplicativos que não usam mais. Um sistema operativo de celular vai fechar os aplicativos antigos de maneira transparente.

Conclusões

Muitas coisas que o Endless ou GNOME podem mudar ou melhorar.

- GNOME tem alguns vídeos para explicar o “overview”. Um jogo ou tutorial podem ser melhor para explicar e ter certeza de que os usuários entendem.
- GNOME precisa melhorar a integração de modems celulares. ModemManager tem as funções que GNOME não usa.
- “Web” precisa de integração com detecção de malware, que ele não tem agora, mas foi uma ideia para o Summer Of Code dos anos precedentes.
- GNOME pode melhorar a primeira tela de todos os aplicativos e do sistema também, especialmente se o usuário não tem Internet para baixar conteúdo.

Muito obrigado a fundação GNOME pelas minhas passagens. Obrigado ao Endless e o Allan Day pela a organizacão. Obrigado ao meu empregador Red Hat pela oportunidade. E, enfim, obrigado à Caro pela correcção!

gom is now usable from JavaScript/gjs

Prodded by me while I snoozed on his sofa and with his cat warming me up, a day before the Content Applications hackfest, Florian Müllner started working on fixing a long-standing gjs bug that made it impossible to use gom in GNOME/JavaScript applications. The result of that initial research came a few days later, and is now part of the latest gjs release.

This also fixes using GtkBuilder and json-glib when the libraries create new objects for the benefit of the JavaScript code.

We can finally use gom to store user data in applications like Bolso. Thanks Florian!

Contents Apps Hackfest 2015

As you might already have noticed from the posts on Planet GNOME, and can find again on the hackfest's page, we spent some time in the MediaLab Prado discussing and hacking on Content Apps.

Music

Following discussions about Music's state, I did my bit trying to gather more contributors by porting it to grilo 0.3, and thus bringing it back into the default jhbuild target.

Videos

I made some progress on Videos' "series grouping" feature. Loads of backend code written, but not much in the way of UI for now. We however made some progress discussing said UI with Allan.

I also took the opportunity to fix a few low-hanging fruit^Wbugs.

Documents

This is where the majority of my energy went. After getting a new enough version of LibreOffice going on my machine (Fedora users, that lives in rawhide only right), no thanks to COPR, I tested Pranav's LibreOfficeKit integration into gnome-documents, after Cosimo rebased it.

You can test it now by checking out the wip/lokdocview-rebase branch of gnome-documents, grabbing the above mentioned version of LibreOffice, and running:

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64/libreoffice/program/  gjs org.gnome.Documents

After a number of fixes, and bugs filed in the Document Foundation bugzilla, we should be able to land this so that you can preview and edit word processing documents, presentations and spreadsheets without going through the heavy PDF preview.

A picture, which doubles the length of my blog post

And the side-effect of this work is that we can start adding new "views" to the application without too much trouble, like, say, an epub view.

Thanks

Many thanks to the GNOME Foundation for sponsoring my travel, the MediaLab Prado for hosting us, and Allan and Florian for organising the hackfest.

Freedesktop Hackfest: Day #3

Wednesday, Mittwoch. Half of the hackfest has now passed, and we've started to move onto other discussion items that were on our to-do list.

We discussed icon theme related simplifications, especially for application developers and system integrators. As those changes would extend into bundle implementation, being pretty close to an exploded-tree bundle, we chose to postpone this discussion so that the full solution includes things like .service/.desktop merges, and Intents/Implements desktop keys.

David Herrman helped me out with testing some Bluetooth hardware (which might have involved me trying to make Mario Strikers Charged work in a Wii emulator on my laptop ;)

We also discussed a full-fledged shared inhibition API, and we agreed that the best thing to do would be to come up with an API to implement at the desktop level. The desktop could then proxy that information to other session- and/or system-level implementations.

David Faure spent quite a bit of time cleaning up after my bad copy/pasted build system for the idle inhibit spec (I copied a Makefile with "-novalidate" as an option, and the XML file was full of typos and errors). He also fixed the KDE implementation of the idle inhibit to match the spec.

Finally, I spent a little bit of time getting kdbus working on my machine, as this seemed to trigger the infamous "hidden cursor bug" without fail on every boot. Currently wondering why gnome-shell isn't sending any events at all before doing a VT switch and back.

Due to the Lufthansa strike, and the long journey times, tomorrow is going to be the last day of the hackfest for most us.

Freedesktop Summit: Day #2

Today, Ryan carried on with writing the updated specification for startup notification.

David Faure managed to get Freedesktop.org specs updated on the website (thanks to Vincent Untz for some chmod'ing), and removed a number of unneeded items in the desktop file specification, with help from Jérôme.

I fixed a number of small bugs in shared-mime-info, as well as preparing for an 8-hour train ride.

Lars experimented with technics to achieve a high score at 2048, as well as discussing various specifications, such as the possible addition of an  XDG_CURRENT_DESKTOP envvar. That last suggestion descended into a full-room eye-rolling session, usually when xdg-open code was shown.

XDG Hackfest: Day #1

I'm in Nürnberg this week for the Freedesktop Hackfest, aka the XDG Summit, aka the XDG Hackfest aka... :)

We started today with discussions about desktop actions, and how to implement them, such as whether showing specific "Edit" or "Share" sub-menus and how to implement them. We decided that that could be implemented through specific desktop keys which a file manager could use. This wasn't thought to be generally useful to require a specification for now.

The morning is stretching to discuss "splash screens". A desktop implementor running on low-end hardware is interested in having a placeholder window show up as soon as possible, in some cases even before the application has linked and the toolkit is available. This discussion is descending into slightly edge cases, such as text editors launching either new windows or new tabs depending on a number of variables.

Specific implementation options were discussed after a nice burrito lunch. We've decided that the existing X11 startup notification would be ported to D-Bus, using signals instead of X messages. Most desktop shells would support both versions for a while. Wayland clients that want startup notification would be required to use the D-Bus version of the specification. In parallel, we would start passing workspace information along with the DESKTOP_STARTUP_ID envvar/platform data.

Jérôme, David and I cleared up a few bugs in shared-mime-info towards the end of the day.

Many thanks to SUSE for the organisation, and accommodation sponsorship.

Update: Fixed a typo

WebKitGTK+ Hackfest: Day 5

Yesterday was our sponsored dinner, at a very nice vegetarian place, followed by some cinema discussions in a bar where the toilets are hidden behind mirrored walls (most strange).

Still, quite a few happenings in code land:

• Nayan is banging his head against the wall with some Accelerated Compositing issues.
• Mario has done a lot of work on enabling WebKit2 accessibility, as well as fixing some WebKit accessibility bugs. He also committed an updated AdBlocker extension for Epiphany.
• Xan wrote a blog post about Web design, and worked on implementation with Claudio.
• Philippe started work on fullscreen support for WebKit2 (this includes, but isn't limited to <video>
• And I wrote a replacement plugin for Flash videos.

The hackfest is drawing to a close, and I'll take this opportunity to thank our very kind sponsors for flights, accomodation and even feeding us in the office so we didn't have to stop hacking for long.









Also a big thank you to Igalia for providing us with hacking beer in the evenings (left-overs from Igalia's 10th anniversary party, a happy coincidence).

Many thanks to Xan, Juanjo and Alex for the hackfest organisation, and the personal chauffeur service, and my most heartfelt thanks to Juanjo for his infinite patience to our tourist needs (such as showing us the Torre de Hércules on a windy December afternoon).

Vegas Baby!

Before: No video, because no Flash, and no MP4 support

After: Video, through Totem's Vegas plugin

Totem's new Vegas browser plugin provides you with a way to watch Flash based videos, without using Flash, using libquvi's growing collection of supported sites.

Code is available from GNOME git this instant. Be sure to pass --enable-vegas-plugin=yes to compile the plugin.

WebKitGTK+ Hackfest: Day 4

The crema de ojuro took effect. While the effects simmered down, code fixing was still in full flow.

• Philippe finished landing the fullscreen fixes for the <video>
• Xan and Claudio started fixing GNOME 3.4 Epiphany design bugs (on the road towards the Web app design)
• Alex, Martin, Joone and Nayan all looked into Accelerated Compositing. They all owe you, dear reader, blog posts full of nitty gritty details.
• Jon didn't spend the day debugging bizarre browsers crashes
• Wingo punched the air as he figured out a tricky memory allocation issue. He also listened to the Thundercats theme tune, in a loop
• Gustavo and Dan figured out a design for multipart/x-mixed-replace support, as used by some streaming IP cameras, and Gustavo started the implementation
• Nayan showed legendary patience waiting for tourists outside a haberdashery
• Dan committed a number of libsoup related cleanups in WebKitGTK+, including a very impressive minus 200 lines cleanup.

WebKitGTK+ Hackfest: Day 3

Another incredible day of hacks, and UI design.

• Carlos added support for downloads to the MiniBrowser, the WebKit2 test application
• Bob, Juanjo and I visited the GUADEC facilities, ahead of next summer's conference
• We had a long discussion about HTML5 applications, hosted and packaged ones, as well as native applications
• The discussion about the new "Web" UI carried on, with some more details being added to the Wiki page
• Andy carried on his work on adding gnome-shell required language features to JavaScriptCore

And despite the crema de ojuro, hacking carries on at the week-end. Join us in #webkit-gtk-hackfest on GIMPNet.

WebKitGTK+ Hackfest: Day 2

After a late evening yesterday, the hackfest started a bit slower, but started picking up pace again with a big ticket item, the WebKit2 GTK+ API discussion. This was the destination for a lot of the WebKitGTK+ hackers, leaving us outsiders, well, outside. The discussion isn't quite finished.

This lead us onto a little lunchtime kick-about. The arrange 6 v. 6 game turned into a 5 v. 4 before getting to the ground, and finish as a 3 v. 4 when two of our most jet-lagged/backbroke hackers dropped out.

And then onto a lunch. And another late evening.

• Philippe fixed more bugs in WebKitGTK+'s fullscreen video playback mode
• Bob uploaded a new draft of his WebKitGTK+ cookbook
• Gustavo was playing Street Fighter whilst increasing the size of his farm on Facebook (in WebApp mode!)
• And the new buildbot is up, running, and churning through test suites in a loop, as fast as the hackers can add new code.

WebKitGTK+ Hackfest: Day 1, Afternoon

After num-num tapas for lunch (and some chocolatey cake), we got back to the agenda, with Jon presenting the design for the Web application, successor (in spirit, and perhaps in code) to Epiphany.

• Andy did the initial work on adding new language features to JavaScriptCore (let and const, as used heavily in gnome-shell)
• Martin and Gustavo worked on a way to automate running the WebKitGTK tests with test fonts, and are working on making all the tests automated, and reproduceable
• Philippe fixed fullscreen support in the HTML5 YouTube player
• Dan fixed the broken security status in Epiphany
• Carlos worked on the WebKit2 support for windowed plugins, and the WebKit side of favicons support
• Philippe, Martin and yours truly discussed sharing of fullscreen media controls (UI and behaviour) between WebKitGTK, Totem and Sushi, as well as a way to make fullscreening smoother.

I hear they didn't finish all the beers for Igalia's 10th anniversary party...

WebKitGTK+ Hackfest: Day 1, morning

After landing in (not so sunny) A Coruña yesterday, we started bright and early today with the WebKitGTK+ hackfest agenda.

We've got most of the topics pinned, as listed on the wiki. If you have more topics to add to the discussion, feel free to drop by #webkit-gtk-hackfest on GIMPNet IRC, and try to drum up interest in somebody championing your topic.

It looks like we could get some pretty cool demos done by the end of this week!

IM, Contacts and Social Hackfest, day four

Day four. People had bad dreams last night due to the huge amount of cheese ingested. Will need to seek counselling. Travis' knee doesn't hurt too much anymore.

Today we discussed the interaction of the “presence chooser” in the Shell's user menu with IM statuses, especially given that we soon hope to make it possible to answer chats without launching an “empathy” binary. A number of options were discussed, and the best one now lives in a bug. (Note that both reports are incredibly detailed, thanks to Will Thompson's amazing screenwriting skills).

Morten then presented his current plan for integration of contacts within the Shell. More details are available on the wiki, and most of the problems and potential solutions were discussed at a high-rate, given the well-known problem space.

We missed out on some interesting changes to account creation (as well as edition) in Empathy/Telepathy yesterday.

IM, Contacts and Social Hackfest, day three

Day three, and the walls are closing in.

Some of our hosts mention they have “work to do” and hide away from light, behind shades.

Alex Larsson showed up, bright and early in the Collabora offices, and most of the day has been spent working on a Folks hit list ^[1] with Travis and Philip as tech leads. Integration of GnuPG contacts metadata (can I encrypt e-mails for that person?), as well as more general IM integration in apps (slide-show sharing for example) was also mentioned, as we hope to share most of this infrastructure.

[1]: Travis' knee was on the hit list, got whacked against a table leg.

IM, Contacts and Social Hackfest, day two

Day two, in the Collabora house, Rob Bradford graced us with his presence, on his birthday, and today started discussing integration of gnome-online-accounts into Empathy/Telepathy[1], libsocialweb and interactions with various accounts systems.

Most of the rest of the pre-lunch hacking was about setting ourselves up for hacking on the above. The afternoon was spent with much of the same, trying to get more documentation for things like Google's Chat authentication, including a draft patch to gnome-online-accounts, Empathy/Mission Control work for this support, and tons of related bug fixes.

The Telepathy hackers also discussed text handling in Telepathy (with the goal of making the specification clearer, avoid problems of "missed" messages, etc.).

IM, Contacts and Social Hackfest, the sponsors

Many thanks to Intel, Red Hat, and the GNOME Foundation for sponsoring participants at the hackfest, and heaps of thanks to Collabora who are contributing a lot of participants to this hackfest, their offices, their coffee machine, and getting us pizza and Nutella dough balls yesterday. Num Num!

IM, Contacts and Social Hackfest, day one

In Cambridge (the proper one, in Cambridgeshire), at the Collabora offices, for the first day of our IM, Contacts and Social Hackfest.

Today, we:

• discussed end-user problems with Telepathy and Empathy's gnome-shell integration (and started the specifications necessary to fixing some of those bugs) (everyone for the problems listing, Danni and Guillaume for the start of bug fixing)
• started working on integrating gnome-keyring dialogues into the Shell (Stef Walter)
• fixed libfolks bugs (Philip), and discussed a potential problem API problem in the folks to evolution-data-server synchronisation code (which will be used in the Contacts API) (Travis, Raul, Bastien)
• packaged up gnome-online-accounts for Fedora (Bastien)
• worked on better high-level tp-glib support for file transfers (Morten)
• HMAC support in glib (Stef Walter)

Tomorrow we'll have Rob Bradford joining us, and probably start talking about GNOME Online Accounts integration with libsocialweb, as a way to kickstart its use all across the desktop.
