Updates on XMPP support in MSN

December 19th, 2011 by xclaesse

Good news for MSN users!

As explained in a previous post, Microsoft added XMPP support to connect MSN. A few days ago, they made it officially supported (previously was a developer preview only).

Thanks to the advice of a Microsoft developer, I even fixed the legal issue that prevented us to enable this by default. Client applications (as opposed to web applications) are not meant to ship the app secret key, even for closed source app (would be too easy to find the key in the binary). So there is a simple checkbox in the app settings to tell it is a “mobile application” and then it won’t need the secret key to authenticate.

All patches got merged and released into empathy (>=3.3.2), telepathy-gabble (>= 0.15.0), and gnome-online-accounts(>=3.3.0).

MSN in Empathy with XMPP

November 3rd, 2011 by xclaesse

A month and a half ago, Microsoft announced that they had added XMPP to their Windows Live APIs. That means that any Jabber client could connect to MSN using our favorite open IM protocol! No more closed protocol to reverse-engineer.

Unfortunately, logging into their service is a bit more complex than just providing a login and password: they support only OAUTH2-like authentication. The good thing is that gnome-online-accounts already supports oauth2 for Facebook and Google services, and I’ve seen while googling that the mechanism is pretty much the same as Facebook. So I’ve downloaded Microsoft’s documentation (registration required to get it), created my own Windows Live application, copied GOA’s Facebook code to start with, and replaced the bits according to MS’ doc and got the login page!

Creating Windows Live account in GnomeOnlineAccounts

Unfortunately, from there it was failing to get the access-token, turns out the documentation contradicts itself. In one place they describe the exact same mechanism as existing code for Facebook, and the other places have small differences… I’ll let you guess which way actually worked ;-)

The Windows Live account created in GnomeOnlineAccounts

Then I had to write in empathy-auth-client (an app usually used to ask user the password) code to instead take the access-token from GOA’s DBus API and give it to telepathy-gabble (our XMPP backend). After fixing a few bugs in telepathy-glib, telepathy-gabble and wocky, EUREKA! Got my MSN account connected in Empathy! Unfortunately it seems the features exposed by their XMPP server are really limited, just like Facebook’s XMPP.

My MSN contacts in Empathy

At the same time, I’ve also added support in Empathy to connect to Facebook GOA accounts, and authenticate them using goa’s access-token instead of having to repeat the password.

Code source is available in bugzilla, waiting for review:

Still, we have an important issue:
This new auth mechanism require us to register a Facebook/Windows Live application. An application consists of a public ID and a secret key. Since gnome-online-accounts is open source code, it means the app’s secret key would be readable from its source code (atm it is given as configure flag), meaning that anyone could make its own malware claiming being the “GNOME” application. This could be considered by Facebook/Microsoft a violation of their service (if I understood correctly). For Google service, it is not a problem because they offer an “anonymous” application and it is user’s choice to accept to grant permission or not (again, if I understood correctly).

Thanks to Collabora for letting me working on this!

Unified contact notifications

September 8th, 2011 by xclaesse

I’ve been working on gnome-shell’s IM notifications recently. The idea is to unify all notifications about a contact into the same bubble.

If you’re chatting in gnome-shell’s embedded chat and then the contact calls you, the “answer” and “reject” buttons gets into your chat instead of popping a new notification.

Call Approver

Then while the call is connected, the notification stay persistent and have a nice phone icon with call duration timer

Ongoing Call

What’s great with that design, is that if someone is calling you, there is a chat available right away to answer “sorry I’m busy, calling you later” and the reject the call.

Patches are attached on bug #656028

Empathy chat theme – call for designers

May 6th, 2011 by xclaesse

Empathy chat view has been supporting Adium themes for a long time now. Those themes are made of HTML, CSS and JS and are rendered using webkit-gtk. Empathy also supports build-in themes using a plain GtkTextView.

I’ve been working recently on improving empathy’s code to support the most recent theme spec as well as fixing rendering issues we had with some themes. I also added a theme preview is settings dialog.

Adium Theme Preview

Designers have been working hard to create the GNOME 3 look & feel, and I think a GNOME adium theme would be great to have for empathy chats. That theme would be shipped by empathy and set by default, so we could drop our GtkTextView-based themes for a massive code simplification.

This is a call for designers: We would like mockups, ideas, and finally a working adium theme to be used by empathy by default.

In a first step, gimped image of what we would like would be enough. Then we can start implementing it with the HTML/CSS.

Suggestions and ideas can be posted on the empathy bug #645920, or on the usability mailing list.

One week with GNOME3

April 25th, 2011 by xclaesse

I’ve installed GNOME 3 ppa on my ubuntu natty last week, and have been using it exclusively since then. To be honest I’ve been ranting a lot against GNOME3 before using it for my day to day activities, so I feel I should share my observations now that I really know it. Here are all the good and bad things I’ve seen, with no particular order. I’ll try not being too polemic (that’s hard exercise for me), please keep in mind I’m not pretending being a normal user; I’m a developer so my needs probably are different.

Bugs

I’ve reported most of the bugs/regressions/unusabilities I’ve observed in bugzilla during the week

648190 gnome-settin UNCO NumLock is not enabled by default
648153 gnome-shell UNCO typing on the desktop could start searching in overview

648087 gnome-tweak- UNCO gnome-shell does not show icons on desktop after login
648084 gnome-shell UNCO Network connected/disconnected notifications stay forever

gnome-tweak-tool

I think I’ve changed the default value for pretty much everything in that tool. I find it sad to unify all gnome-settings in a new shiny and consistent UI, and then rely on a completely different and inconsistent tool for the rest. I know it is extremely hard to define what options to show the user, but IMO this feels like an easy solution to avoid the problem instead of facing it. Maybe we could simply make gnome-tweak-tool just another “tweak” icon in gnome-control-center, so at least it gets linked from there. That would feel more integrated.

GNOME thinks I’m disabled people

Considering all the effort to keep UI as minimum as possible, with no applets on the panel, no way to tweak it at all, and still I’m forced to have that menu for disabled people on my panel. I completely agree it is important for people needing those options to have a way to quickly access them, but this seems really really overkill to me. At least this could be yet-another option in gnome-tweak-tool?

Also please rename those “universal access”; do I really have access to the whole universe in one click? At least this sound silly in the French translation…

ctr-del

I’m probably the last geek to use nautilus to manage my files instead of gnome-terminal, but this change in nautilus to use ctr-del to delete a file surprised me. For the first days I’ve been thinking it was just a bug that nautilus can’t delete files and I used right-click context menu to move to trash. Then I discovered by asking on IRC this was actually intentional!! I won’t even start telling this is wrong, but simply ask one simple questions: How is CTR-DEL discoverable? Pressing DELETE does nothing, just silently ignoring me. My first intuition was of course the context menu to move to trash, and no shortcut is shown there. Since any computer user since in win95 (or even earlier?) are familiar with DELETE key to delete a file, I think it is important to have some notification telling the user what to do.

me-menu

The menu on the right of my screen that kindly reminds me my name, next to the disabled-people-menu (not only GNOME thinks I’m blind, but also that I have Alzheimer), looks like an IM menu to me. It starts with my fullname (which I use as alias on my IM accounts) and a chat bubble icon like the new Empathy icon. Then it have Available/Busy items which are totally IM vocabulary, followed by “My account” which surprisingly does not open Empathy account settings… and this ends here, the rest has nothing to do with IM… I do totally like having IM being first-class citizen in GNOME UI, but something looks wrong here. Especially since when I boot the computer, the menu says I’m available, but all my empathy accounts are actually offline. Changing to busy, back to available, etc does not change my status in Empathy; unless I first start empathy’s contact list view. I know this is partly because Empathy/Telepathy are not yet ready to fully integrate IM into the core desktop.

My vision of Telepathy integration into the desktop, is that “Empathy” as an app does not really exist. We have views for different kind of IM informations (contact list, chats, file transfer, presence, account settings, etc). Those views are provided partly by empathy widgets, but also by gnome-shell itself (presence in me-menu, embedded chat). The views are apps started on-demand but are not THE im application. So empathy’s main window is (should) just a view of the contact list, it does not need to be running to be available on XMPP and receive IM messages.

I have great hopes for 3.2 :D

Embedded IM chats

This is totally awesome! I love it so much! My only concern is the empathy status icon still blinking even after I replied messages in the embedded chat. During the week I’ve almost never actually opened the empathy’s chat window, I’ve been always chatting in gnome-shell directly. If gnome-shell’s activities search could match my contacts names too and let start chat/call, I think I could even not need to see empathy’s UI at all.

non disturbing notifications

Thanks god for smartly hiding notifications, I’m spending much less time in liferea since I don’t see anymore when my RSS are refreshed. I also totally like the rhythmbox’s notification when changing song, that let you pause/skip easily without needing to open the rb window (I’m using multimedia keys most of the time though).

It could be improved a bit though, for example when a new IM message arrive when I was away, I don’t see any notification until I open that bottom panel.

The wow-effect

I think gnome-shell is a perfect balancing between modern OpenGL desktop, but still looking professional. When compiz started showing tones of technically impressive 3D effects, I’ve always though its nice, but not professional. Now gnome-shell succeed in take advantage of technology, but not over-using it.

Launchers

I though it would be worse, but still I’m missing my launchers for some apps. I’m used to open a lots of gnome-terminal everywhere, for example. I had launchers in my gnome-panel before. I’m getting used to keyboard shortcuts now, but still I miss them a bit. I wish the launcher bar in the activities view could be visible on my desktop, and smartly hide when a window is on the border, like the ubuntu unity.

multi desktop

This is also something I though it would be worse. But still I can’t get totally used to it. It should have a way to spin some desktops to they don’t get removed when empty. Since they are dynamically open/close, I sometimes get lost in my desktops, having the preview image when using ctr-alt-up/down could help I think.

Also I miss a direct way to switch desktop using the mouse. May I suggest having the desktop bar we see in activities visible on desktop too. Just like suggested for the launchers above, it would hide like it does for unity’s launcher bar.

The shutdown story

You’ll be surprised, but I personally don’t miss the shutdown option. I almost always suspend anyway. After important upgrades, ubuntu should add a reboot option there; is such distro extension possible? A tooltip or something could suggest ALT magic key to reboot/shutdown, though.

Google/Wikipedia

Wikipedia makes perfect sense for an Open project, but is GNOME paid (like Mozilla AFAIK) for that Google advertisement at least? Even Internet Explorer lets the choice.

Developer feeling

This is probably partly because I have less time to contribute to GNOME this year, but I feel its getting more difficult for developers not having full-time job working on GNOME to contribute. I see 2 main reasons for this:

  1. Gtk3 breakage: In previous cycles it was almost trivial to build Empathy master on latest stable Ubuntu release. Only a few telepathy packages were needed from a ppa. With this GNOME3 cycle, it was mostly impossible to even see what was being worked on. We had the choice between installing totally unstable distro (not even Ubuntu sadly) with a full GNOME3 desktop, or build the world with jhbuild, which I always considered (wrongly?) a pain to get stuff working.
  2. Decisions are more and more made by UX “experts” who knows better, and make their plan partly behind closed doors. I have to admit they did mostly an amazing work, but as user and occasional contributor, I feel I’ve lost my voice. I don’t think anymore I can change stuff that I don’t like in GNOME, not because of technical reasons, but because GNOME is now part of a bigger plan. This is probably a good thing for marketing, but makes the hacker in me sad.

Hopefully point 1 won’t be the case anymore for GNOME 3.1 cycle, and point 2 is maybe more a feeling than a reality and could surely be improved.

Importance of fallback mode

No, not everyone has OpenGL running just fine on linux yet, and no not only proprietary drivers are broken. Just 2 examples on my laptop with intel GPU:

  1. gnome-shell won’t startup in a VM using virt-manager
  2. Playing an OpenGL game with wine works just fine when I launch it from gnome2 desktop with metacity and not effect, but is terribly broken rendering when launch from gnome-shell.

My conclusion

GNOME3 is a good base for upcoming releases. Better than I’ve though before using it everyday, but still lots of place for improvement and not yet the perfect release I hoped. I only hope designers and main hackers will be flexible enough to let it involve to something that can make everyone happy, but still rigorous to keep a consistency. Hard task, really.

ssh-contact has a new home

July 29th, 2010 by xclaesse

Thanks to fd.org admin, Tollef Fog Heen, SSH-Contact now has a bugzilla (product=”Telepathy” and Component=”ssh-contact”) on bugs.freedesktop.org. The new place for release tarballs is here.

Debian unstable and Ubuntu maverick already has it packaged, Ubuntu lucid users can get it from our telepathy ppa. I don’t know for other distributions, but if you are packager and love ssh-contact, please push it to your favourite distro :D

Various plugins for your N900 addressbook

July 26th, 2010 by xclaesse

Marco Barisione and myself worked on some plugins to extend the N900′s Contacts application. I grouped them in the fremantle-contacts project on gitorious. You can find on the project wiki page a short description of what we have already. Here is an overview:

Contacts Merger

Plugin to find probable duplicate contacts and allow the user to easily merge them.

Available in extra-devel maemo repository, package name: “contacts-merger”

Extended Contacts Search

Plugin to extend the live search feature on addressbook’s main view. It will also search in contacts phone numbers, nickname, emails and IM usernames.

Available in extra-devel maemo repository, package name: “extended-contacts-search”

Contact Zoom

Plugin to add a Contact Zoom menu option it Contact starter view. The Contact Zoom opens a window with all information about that contact displayed in bigger font, to make it much more readable.

Available in extra-devel maemo repository, package name: “contact-zoom”

ssh-contact 0.2 released and packaged

July 26th, 2010 by xclaesse

SSH-Contact 0.2 fixes some minor issues. Thanks to Laurent Bigonville, it is now packaged in debian unstable and ubuntu users can install it from telepathy ppa.

Please read the FAQ.

It will soon be hosted on freedesktop.org, as part of the telepathy project.

Telepathy-ssh renamed to ssh-contact and released

July 16th, 2010 by xclaesse

I’m glad to announce the first release of ssh-contact, previously known as telepathy-ssh but renamed because there is already so many telepathy-foo projects (mainly ConnectionManagers) that it could be confusing.

It now has a great interactive CLI, letting you select which IM contact to connect. Of course it display only the contacts who installed the ssh-contact service.

Distro packagers, you can find the ssh-contact 0.1 tarball here. I’ll probably host the project on freedesktop.org in the future.

Feedback would be appreciated!

SSH your IM contacts

July 12th, 2010 by xclaesse

Did you ever wanted to connect to your computer but couldn’t make an SSH connection because it is behind a NAT, dynamic IP or firewall? Telepathy-ssh is for you!

Telepathy-ssh is a simple client/service program that make an ssh connection through a telepathy Tube.

$ telepathy-ssh-client gabble/jabber/testman2_40jabber_2ebelnet_2ebe1 testman@jabber.belnet.be

Of course I’m planning to make the CLI a bit better. At least I would like to let choose the account between a list instead of having to type its ID manually. You can know your accountID using “mc-tool list” command. Also since the telepathy tube creates a local socket on which the ssh client connects, you see that it says it’s connecting to “127.0.0.1″, is it possible to tell ssh client to display another hostname?

I wrote that tool to make easy to connect my mother’s computer remotely, whithout dealing with her dynamic IP and NAT. If you also find that tool useful, and have suggestions, feel free to post a comment, or even patches :)
