Today I got an invitation for Jolicloud, I was really excited about that project and I’m really happy for this opportunity to test it.
Jolicloud is not the first Linux distribution I have installed on my Samsung NC10… I’ve tested also Ubuntu Jaunty/Karmic, Fedora, Arch Linux and Moblin (latest snapshot).
Which is the technology behind Jolicloud?
Basically Jolicloud is a derivate of Ubuntu Netbook Remix with wide Prism usage across the desktop environment: the majority of “applications” you have seen in the screenshots are small packages which provide an independent Prism session on a specific website: for example, if you install the twitter application you will get a new icon inside your application list, that icon will start a new fullscreen Prism session for twitter.com.
Common desktop applications are also included, like Firefox or VLC, but it is highly focused on web services.
Installation
It is just like Ubuntu, nothing more/nothing less (you are in the Jolicloud desktop, but the installer is the same used by Ubuntu).
First Run
As said, the “core” is an Ubuntu Netbook Remix, so we firstly see an Usplash booting sequence (nice and simple theme)…
Followed by the GDM session (simple and nice theme too)…
After the login procedure the desktop environment starts. It’s a GNOME desktop with the Netbook Remix session: the custom panel on top shows the title of the current application in the middle, a list of the running application on its left and the status icons on its right. In the center of the screen Jolicloud asks to login on the website and then it opens the default screen you might have already seen (the dashboard shown in the screenshots is nothing more than a Prism session running http://my.jolicloud.com).
Jolicloud is now ready.
The home screen, dashboard, how do you call it 
As said, the main screen is a Prism session (so a website, no Clutter, no Cairo, no Gtk+…) with useful links to your applications and your settings. It is great to see how it is simple to use, really: installing and removing applications is a matter of a click, browsing and viewing the catalog of applications is very easy. For everyone. I like it.
Running applications
The separated fullscreen Prism sessions work surprisingly well… In the reality you’re running a web browser, but they give you the feeling that they are just like normal applications: if you run gmail, twitter, facebook (etc etc) you have their icons in your taskbar and you switch between them like they were a real application.
It’s the web now the protagonist of your netbook because you are actually using each web 2.0 service as an individual application: something that has been imagined for years by almost every company (Microsoft too) realized in Jolicloud really well.
A desktop replacement?
This distribution is absolutely amazing to surf the web when you’re on a train, in the university, when you just want your social websites up and running, when you want to update all your services and work with your documents.
But just like Moblin, in my opinion it is not meant to replace your Ubuntu… it will be likely added to your grub in a small partition dedicated to your social virtual space. And that is a good thing… when you need you have a quick access to the web. Great!
Comparison with Moblin
They are two completely different projects, even if they share the same love for the web.
Moblin is like a smart interface for your netbook providing a mix of useful applications with incredible tecnologies behind (KMS, fastboot, Clutter…) optimized for your netbook, with Jolicloud the web becomes your operating system (it provides the applications) trough an efficent environment for your small laptop.
I’m sure they will live together on my hard disk soon

After having tried thousands of different drivers, kernel versions, patches etc etc… I’ve finally found a combination that made me excited (wohoo!).
I own a Samsung NC10 with an Intel Atom N270 and an Intel GMA 950 (i945). I’m running both Arch Linux (i686) and Ubuntu jaunty (lpia).
Few notes:
- This how to should work with any netbook, since they share almost the same hardware.
- I haven’t used a benchmark, but applications (Firefox, Gnome Do’s Docky, KDE 4 and more), and the difference is so visible that it doesn’t require a benchmark.
- I don’t know if it depends on the lpia architecture (I’m running Ubuntu lpia) or some patches applied to the drivers, but Ubuntu’s 2D graphics are a little bit faster than my Arch Linux installation with kernel 2.6.30 and drivers 2.7.1 (same versions).
- I had the boost in both Arch Linux and Ubuntu, though Ubuntu is faster.
- I’ve compared the 2D graphics with Moblin too, but its newer drivers using UXA are noticeably slower (Firefox/Gecko is incredibly slow when scrolling heavy webpages like facebook or my custom gmail).
- Newer Intel drivers (2.7.99.x and similar) support only UXA acceleration, and they perform a little bit slower than 2.7.1 without greedy migration heuristic (unfortunately that means a big difference). Greedy migration heuristic does not work with UXA.
- With this new combination, 2D graphics are really close to my Windows XP installation (Firefox scrolling).
Instructions (Ubuntu lpia combination, adjust the steps to your distro):
- Install kernel 2.6.30 from this ppa (even if it has the “nc10″ tag, it doesn’t have custom patches and should work with any netbook).
- Upgrade your Xorg Intel drivers with the 2.7.1 version on the same ppa.
- Enable greedy migration heuristic creating an empty /etx/X11/xorg.conf with those lines:
Section "Device"
Identifier "Intel"
Driver "intel"
Option "AccelMethod" "exa"
Option "MigrationHeuristic" "greedy"
EndSection
- Optional: install client-side-windows Gtk+ branch (helps Gtk+ scrolling and resize).
I really hope you will get the same boost I had, and I’m looking forward to newer Intel drivers: it is just question of time… the team rewrote both xorg driver and the DRM code to ensure a great future to these video cards, and the performance drop is physiological to the transition… I suspect UXA will achieve those performance in less than a year…

I had an idea, I don’t remember exactly who asked me for it (maybe Gyb), but it is really simple: rename all menubarstyle, toolbarstyle, menuitemstyle (etc etc…) into style[menubar], style[toolbar], style[menuitem]… same thing for other options (color[scrollbar], color[focus], shade[lightborder] etc etc…).
We actually need to write a little parser for them in murrine_rc_style.c and/or clearlooks_rc_style.c.
The thing is: I don’t have time for it in these months.
So, if someone wants to write a small patch for it… it will be merged!
Have a good weekend…

Murrine is a Gtk+ engine, written in C language, using cairo vectorial graphics library. By default it comes with a modern glassy look, elegant and clean on the eyes. But it is also extremely customizable, and allows the user to achieve an incredible variety of styles.
Wow, new rockin’ release!
Enjoy.
Download the source code!
Changelog
Too many changes to be listed, let’s take a summary.
This new version is extremely customizable with a huge number of new
options. Those new options allow the user to achieve an incredible
variety of styles.
In order to add those features the engine was rewritten in many parts,
sometimes even 2 or 3 times! This results in a simpler code, more
readable and more maintainable, with a lot of custom code moved from
each widget drawing function (before) to a general murrine drawing
support file (now). For example adding a new glaze style will now cost
about 20 lines and it will be applied immediately to every single
widget.
Murrine can finally use the alpha channel to draw a real transparent
theme, all it needs is an application using the RGBA colormap and a
theme with the rgba option enabled.
During the whole development, murrine was kept in sync with
every bugfix that hit gtk-engines, so this new version can also be
considered much more stable than the previous one.

UPDATE: should be out soon http://download.gnome.org/sources/murrine/0.90/
I’m still not sure but maybe I will publish a Murrine development release in this weekend (with development I mean it won’t be called 1.0, maybe 0.90 or similar).
I’d like to have it included in Jaunty, because ubuntu is actually shipping an old bugged svn snapshot and I’m a bit tired of closing bugreports about that obsolete version.
If you have some last requests, please take a look at that post.

I may have some time this weekend and the next weeks to continue working on both Clearlooks and Murrine GTK+ engines.
I need ideas 
This post remembers you that I’ve opened a section where you can easily submit your mockups for Murrine. Use gnome bugzilla for Clearlooks.

After reading Aruiz and Dylan I think I could ask your attention on that topic.
I like Dylan’s idea of a Do-ified GTK+ 3.0, it seems innovative, making user interaction more accessible and faster. At least, this is my personal opinion.
From Dylan:
@Cimi: it would be great to see Do-like functionality incorporated in Gnome 3, not just on the desktop, but also at the application level. Programs like the Gimp or Inkscape use a lot of keyboard shortcuts that may be hard to memorize all-at-once. Using the Do-metaphor *within* the application will let you invoke functions quickly, and discover keyboard shortcuts in the process.
I don’t have anything against Mono, but for Do to become an integral part of the Gnome Desktop, I think it would almost have to be part of GTK+, because it needs to communicate with other parts of the interface to know which functions are applicable given the situation (it makes no sense to list ‘Crop to selection’ as an option when nothing has been selected).
I must agree with him, sometimes keyboard shortcuts are complicated to use: how can I remember alt+g, alt+k, alt+y, alt+s, ctrl+alt+h, ctrl+alt+h+super+t+f12+enter+backspace? (omg I’m not playing the piano 
I just want to use my computer!!!)
Typing “fullscreen” is easier than remembering Totem is using “F11″, Banshee “F”, another application “Ctrl+Alt+F” and so on… And while “fullscreen” is something known and famous, what about exotic shortcuts that almost each application has? Those are just useless… and dangerous! Imagine if I press “Ctrl+W” on an important document because I forgot the right command…
Now, your thoughts please

29 January 2009 will be another great day for our free software desktops, GNOME Do 0.8 is released!
This is a fantastic release: it’s not just few bugfixes, it’s much much much more! Jason Smith did an amazing job rewriting the whole graphical interface code, allowing Do to feature shiny animated interfaces… for all your tastes!
Send to pastebin, imageshack, manage your music collection, access files, browse google docs, open conversations, add bookmarks, control your jedi lightsaber… EVERYTHING: just with one simple key!
GNOME Do 0.8 will dramatically change the way you interact with your desktop, saving a lot of time for better moments with your girlfriend (or your lightsaber!) I would really love to see GNOME Do or something similar in our GNOME 3.0 shell. This is the key, the Do key.
While I mentioned Jason for the graphical part, I can’t forget David Siegel, Alex Launi, Chris Halse Rogers and every contributor!!! They did an amazing job, they *are* an amazing team.
So, that’s all folks: go and spread the voice
It’s time to rock on for 1.0!

I’ve sad news for you all.
This year I will be at the university during the weeks and, since I don’t have a laptop, I’m actually forced to stop the development of Murrine, Clearlooks and all other projects in which I put my effort. I hope you can help me to not have to stop working on Gtk+ software.
Please Help Me
At the same time, being a student, I don’t have the means on my own to buy a laptop, even a cheaper one. So I am asking for your help by means of a donation. Only with a laptop I can continue to organize the work needed for a fully functional system-wide transparent RGBA mode in upcoming GNOME release as well as following your requests and adding features.
So, if you enjoyed my work these past years and you want to keep these things alive, or if you just want to give me your personal *thank you for creating Murrine* or *thanks for the Clearlooks restyling* please consider a donation. All funds received will be used only for supporting the development of my free software projects.
I don’t know how much I can achieve from this, netbooks start at 400$ and if I get more I can hack on more advanced effects
I’ve opened a new section in the Murrine’s website, Feature Requests, where the most popular features could become a reality when I can code again. It is like my thank you for your donations. In that way you’re sure you’re donation will be used to the development. And after donating you can see some of your dreams implemented
By the time I’m writing the post there are seven pending features:
But these are just a few, with your donations I can implement them and what you like!
I would like to thank everyone will help me.
Status of the Gtk+ RGBA support
For the guys who missed my
first RGBA revolutionary post, they could see
how a Gtk+ engine could be transparent
Enabling RGBA
inside applications was a test, but the real goal is to set RGBA system-wide, so
every Gtk+ interface will have this channel and all of its benefits (
not only transparency, but also rounded menus, fancy tooltips, notifications and visual effects…).
- To achieve this there was a bug in the system tray which was fixed in trunk few days ago, and another patch pending in gnome-panel that needs approval.
- Got it, the next step is to write a small patch for Gtk+ in order to give the user a xsetting or an environment variable to enable/disable the RGBA visual/colormap. There was a discussion months ago, I ask Gtk+ devs for their opinion on this topic.
- Reached this point, we need to start testing applications, and submit patches to the applications that behaves in a wrong way (for example Gnumeric or Abiword), or poke Xorg guys if we will find new Xorg bugs.
If everything is ok, GNOME will be fully capable of using RGBA colormaps for its themes (wow a rounded gnome-panel!)
Summary of Murrine Projects
One of my dreams is to involve more and more people, and coordinate a group of talented themers/artists with the common goal of creating visually-satisfying and high-quality themes using and improving Murrine engine to its best.
- Murrine: Since the latest stable release (0.53.1) I’ve rewritten the code two times, I’ve fixed bugs, I’ve simplified the code improving the rendering speed, I’ve added a huge number of new options and now, thanks to the Clearlooks style code it is really modular and supports different styles like Glossy, Classic, Gummy, Inverted for Clearlooks. For example: writing a new style for next Ubuntu releases is possible without a rewrite, I just need to add the new drawing code, choose a name for the gtkrc option, and map it If we ever had released a 1.0, this would definitely qualify for a 2.0.
- Website: First of all don’t forget to register to the Murrine Website, a place where you can easily submit your themes, send your mockups, request your features, download per-application RGBA patches, ask questions to themers, vote your favourite contents! More sections could be added, email me if you have an idea.
- Murrine-Themes: From September I’ve asked lucazade to start developing a high quality set of themes for the next-gen Murrine release, using options to achieve original looks while providing an usable everyday visual experience. This project, called murrine-themes and hosted on launchpad, it is still far from being high-quality, but I’m sure that in his hands and in your hands (if you want to participate) it will be a must-have complement to the engine.
- Contest: The best themes published in the Murrine Website could be part of Murrine-Themes!
- Murrine Configurator: Two Australian guys started developing a new kind of configurator, hosted on launchpad, compatible with every engine, that will make Murrine theming fun as a video game If you are interested in joining the development or starting a configurator optimized for Murrine (it will be better of course, seen the high number of options), ask and you’ll be part of this great theming crew.
- Bazaar Playground: Murrine is first of all free software, why don’t play with the source code? There’s also a launchpad mirror, where you could play with your own branches! And why not, good modifications could be merged!
If you want to talk directly with the few guys that populates the chat, if you want to keep track of the development, don’t forget to join! We are (well, there are just few guys actually) on Freenode, channel #murrine. Add it to your autojoin!
Status of the Official GNOME Theming Projects
The “Clearlooks restyling” you’ve seen from 2.19 was done to achieve an enjoyable professional look, while being original (Clearlooks is not a copy of OS-X or Vista). A theme that could be used for years without getting annoyed
I don’t have in mind another restyle for Clearlooks, but there are a lot of minor things that require always a bit of work: starting with bugfixing to some gnome-panel theming (which will require more work). Two things that were planned for 2.24 are a compact theme (for small screens) and a dark theme for Clearlooks. I would really like to help more Benzea on this side, he is totally praiseworthy.
I would like to provide another good set of free wallpapers, at least in the gnome-themes-extras package.
Another thing in mind, but I won’t personally code for this, is colorscheme support for Gtk+ themes! You choose a theme, click on the color section of the appearance capplet, and select through a combobox or a listview the colorscheme you like. As well as storing a new one.
Donations are important to keep me inside the GNOME Art Team.
Spread the Voice
This post is really important because it’s a summary of the future Gtk+ theming, where I consider Murrine as a great tool for artists and themers. Please spread the voice on Digg and other social websites so everyone could learn from this.
