Few people would argue that the Ubuntu Software Cenre in its current forms needs a makeover. Thankfully it is getting one, although whether or not it will be ready in time for Oneiric’s release in October is a whole different debate.

Earlier today I pulled the latest development branch of the Ubuntu Software Centre to check in on development. Upon running the ‘software-centre-gtk3′ file inside this stunning Software Centre revamp appeared my desktop

New and exciting ways of interacting with files are being explored in GNOME 3. 

Rather than just navigate to and ‘view’ your files the following designs show off features and interfaces that are helpful, modern and in keeping with the modern GNOME desktop.

And before you sigh at the sight of yet more pretty mockups never to be: the following two designs are said to be “definitely happening” according to our GNOME source.

The first design is called “Music”, and was designed to give users a “simple and elegant replacement for using Files to show the Music directory.”

When I first saw the designs for ‘Documents’ I thought ‘iTunes for Documents’ – and that’s actually not a bad idea!

Much like ‘Music’ above ‘Documents’ is designed to provide users with a better alternative to ‘…using Files to show the Documents directory’.

OS X Lion introduced natural/reverse scrolling where by “content tracks finger movement”. 

If you’ve ever used a touchscreen smartphone you’ll already be familiar with how this works: you drag down to scroll up; you drag up to scroll down.

‘Natural Scrolling‘ by Charalampos brings reverse scrolling to Ubuntu.

‘Natural Scrolling’ requires a handful of dependencies: -

couch-db python-desktopcouch-application gawk

Once the above dependencies have been installed you can proceed to download the .Deb installer.

dl.dropbox.com/u/1111373/NaturalScrolling/naturalscrolling_0.2.4_all.deb

Double-click on the .Deb to open it in the Ubuntu Software Centre. Hit the ‘Install’ button to install, then launch from the Dash by searching for ‘Natural Scrolling’ once completed. 

You can toggle Natural Scrolling using the Application Indicator present in the top panel. When Natural Scrolling is active a small ‘tick’ will be shown. Click again to disable it.

Note that at the time of writing the ‘Autostart at login’ feature is broken.

The theme is called ’elementary Dark’ and, according to the artist who has knocked it together, is a ‘soft and subtle dark theme based on the higly popular and modern elementary theme from the elementary project.‘

It uses the latest version of the eGTK theme from elementary, although only includes GTK2 and Metacity variants. A GTK3 port will released at a later date.

As dark theme goes it’s pretty darn dark. I’m not a resident in Fansville when it comes to dark themes, and elementary dark didn’t do anything to sway me. Whilst dark themes are great for specific kinds of applications, in general use I find them hard on the eyes, confusing to look at (particularly where icons use dark colours) and in some kind of pseudo-psychological attack they leave me feeling a bit, well, “meh”.

I am but one person, and I know dark themes have just as many fans as, well, whatever the polite term for an ‘un-fan’ is.

If you fancy it you’ll find the theme ready for download on ~satya164‘s DeviantArt page at satya164.deviantart.com/art/elementary-Dark-244257862

NB: The theme  looks best with Nautilus-Elementary - See here - and the elementary icon theme – see here - installed.

Next week Alpha 3 of Ubuntu 11.10 will be released, so everybody is currently trying to get their latest updates in and everything tidied up for a release.

For today I got an update from Ubuntu Desktop Team hero Sébastien Bacher, so if you’re interested in any other aspect of Ubuntu Oneiric, I’d refer you to the oneiric-changes mailing list and the big picture specification status overview instead. So what’s happening with the Ubuntu Desktop?

As you all know Ubuntu 11.04 (Natty) stayed on GNOME 2.32 because the GNOME3 schedule was too short to integrate the new version correctly in the release, but the GNOME3 team (which mostly consisted of non-Canonical contributors) did a great job on getting GNOME3 in a PPA.

For Ubuntu 11.10 (Oneiric) we decided to land GNOME3 early, to update to 3.0 while doing merges from Debian, stabilise a bit and then go for GNOME 3.1 and track the unstable series.

Thanks to the work in GNOME3 team PPA the first round of updates went smoothly and we landed GNOME3 around the UDS time. We switched to GNOME 3.1 after UDS, starting by the platform pieces and then the desktop ones. GNOME 3.1.4 tarballs were due this week and thanks to the rocking Desktop team contributors it’s mostly in Oneiric already.

Let’s have a look at the Desktop version status overview:

• Green mean “up to date”, yellow is “up to date but with a new revision in Debian”, orange lines indicate packages that need an update.
• The page lists the default installation set but you can click next to the first column title to display extra “desktop-ish” components not installed by default.
• We take notes of what need to be done and what is worked on.

You can also see a “Still to claim” category with updates which need to be done, those are packages any contributor is welcome to work on, the etherpad has also a list of things which still use gconf or gtk2, which is a target for the next LTS (Ubuntu 12.04).

This means: our stack is up to date and GNOME 3.1.4 is mostly in oneiric by now.

What is coming next (or where we still need some help):

• the updates listed on versions overview and in our Etherpad notes
• fix the integration issues listed on etherpad and in the desktop-o-gtk3-gnome3 spec
• transition gtk2 code to gtk3 (currently: ubuntu-sso-client, ubuntuone-control-panel, libubuntuone, system-config-printer, sessioninstaller, onboard, openssh, libgnome-keyring)
• transition gconf code to gsettings (currently: unity, ubuntuone-client, onboard, ubiquity, indicator-session, notify-osd)
• We might be a bit short on ressources to bring back the screensaver animations, but we should at least make the screensaver lock screen be more unity like (more details)
• we still want to integrate gnome-online-account and some of the new GNOME 3.1 features to the oneiric installation
• the new gnome-contacts needs to be packaged
• clutter and clutter-gst need to be promoted to main (since cheese, totem and empathy will use them)
• some patches in our GNOME packages have been commented to not block the GNOME3 updates but need to be refresh and turned on
• there’s a couple of desktop bugs that would be nice to get fixed, especially those targetted to Oneiric because we think we should fix those this cyle, (bugs not assigned free to be claimed – if you want to work on an assigned bug please contact the assignee first)

Thanks a lot Sébastien for the update!.

Keeping up with Facebook on Ubuntu has never been an issue; there are a tonne of applications available that let you do everything from read your stream to upload photos and update your status.

If that much Facebook on your desktop sounds like too much you might benefit from   ‘Faccialibro‘ – a simple Unity Launcher applet that lets you know of unread messages, notifications and friend requests – and nothing more.

Want to add it? First install ‘python-facebook‘ (click link to install)’.

The applet can be downloaded from the site of the of the developer, mirko, at mirkoweb.org/Faccialibro.tar.gz

Let the download fully complete, then extract the archive into your Home folder.

Next, open into your Home folder and press CTRL+H to reveal hidden file and folders.

Locate and open the folder ‘.faccialibro‘ (note the period proceeding the name)

Inside this folder right-click on the file named ‘Faccialibro.desktop’, selecting the ‘Properties’ item from the menu.

Replace the name ‘mirko‘ present in the ‘Command’ field to that of your username. Your username can be seen next to the Home folder icon at the top of the Nautilus sidebar. To apply the icon drag the ‘facebook.png’ icon into the icon field square. to the left of the entry fields.

Lastly select the ‘Permissions’ tab, where you should check the box next to ‘Allow executing file as program’.

All that remains now is to drag the ‘Faccialibro‘ file onto the Unity Launcher so we can use it: -

In order for Faccialibro to receive notification of alerts it first has to be ‘authorised’ with Facebook. This isn’t a hassle; click on the Faccialibro icon now in your launcher to launch Facebook in your browser where a prompt will appear asking you to ‘Allow’ permission to the app.

Once authorised you can close the window and let the applet do the work.

Ubuntu – The most popular Linux distribution for desktop users (with an exponential growth in past few years) and Android – one of the most popular mobile operating system, also based on Linux kernel; developed by Google Inc.

Ubuntu 11.04 (alias : Natty Narwhal) or older versions such as 10.10 (Maverick Meerkat) or 10.04 (Lucid Lynx) is now becoming the dominant choice for programmers and web developers probably due to the features (cool desktops (window manager, e.g Gnome, KDE..), open source applications, tools, no licensing cost…) and flexibility available on Linux based operating systems. Android stable version 2.3.5 (Gingerbread) was released a day ago.

Do you want to develop android apps using Linux based distributions, then this post will explain you about installing Android SDK (Software Development Kit) on Ubuntu, despite of that you can apply the same procedure in installing android sdk on other Debian based GNU/Linux OS such as Linux Mint.

Before diving into installing steps for android sdk in Ubuntu 11.04, I assume you have already installed -

1. JDK (Java Development Kit)
2. Eclipse IDE

Now, you can install Android in two simple steps :

Download SDK Starter Package
Then extract the package(s) either by right clicking -> extract or do it from Terminal :

Open Terminal (CTRL+ALT+T) and move on (use cd target_directory) to the directory where you have downloaded the packages.

tar -xf android-sdk_r12-linux_x86.tgz

android-sdk*/tools/android

Android SDK and AVD Manager will be started with the above command,

now you just need to select the packages (first one you get after expanding Android Repository, is probably mandatory and select the SDK platform version for your targeted device, documentation, sample apps…or any third party Add ons if required) you want to install, then click on ‘Installed Selected’ button; wait for the Download/Installation to complete. (Since the selected packages will be fetched from Internet you need an active internet connection during installation procedure)

start Eclipse and go to Help > Install New Software, then click on Add. Enter the ADT Plugin in name and the following address (in case of any problem, try http instead of https (The secure version of http protocol).. or simply click on archive and locate the manually downloaded ADT plugin file ) as Location.

https://dl-ssl.google.com/android/eclipse/

Then click on Next -> select developers Tools -> Next -> Finish.

Now, it’s time to configure ADT Plugin, Click on Window -> Preferences -> Select Android in left panel and locate the Android SDK directory, and hit Apply/OK.

That’s all.

Winamp is a media player for Windows XP/Vista/7.. and now it’s also available for Google Android. Winamp is one of the most popular and powerful media player among windows users. Winamp is specifically known for it’s playlist, skins, and a bundle of advanced features that allow you to customize it effectively. Winamp is a freeware application i.e basic version is available free but you need to pay for it’s pro-version.

Are you looking for Winamp on Ubuntu? In fact, Winamp is available only for Windows (and Android). That’s not exactly true because Winamp vs 3 (The latest stable version is Winamp 5.621, released few days ago) Alpha version was also released for Linux based OS (probably the RPM packages, for Linux distributions like Fedora) but it’s not available anymore for Ubuntu or any other Linux distros. So in this post you may notice some free and open source media players equivalent to Winamp not only in features but also in look and feel (by using Winamp skins).

Audacious is a free and open source (Released under GPL) media player (more precisely an audio player) and provides high quality audio output. The other main advantages is that it consumes very less computational resources and supports a variety of formats. Audicious started a fork (Forking in software development means starting an independent development on a project after getting the source code legally from the original developer) project the BMP (Beep Media Player, which also started as a fork project of XMMS)

How to install

sudo apt-get install audacious

We all want the latest features and changes an app has to offer, and for many of us that means using unstable, beta or sometimes even alpha quality software.

This ‘bite of the beta pie’ approach has drawbacks: application performance may not be ideal and you risk files being trashed by buggy new features.

Enter Glimpse which lets ‘unstable’ applications run alongside stable applications in a ‘sandbox’, making the testing of alpha software (for curiosity’s sake or more) a relatively fear-free experience.

The developer of Glimpse, Sergey “Shnatsel” Davidoff, explains: -

“Applications run in Glimpse are allowed to read your real data, but when they write to it or modify it in any other way, all the changes stay within their sandbox. Your real files on your system are left intact.”

Download Glimpse

Glimpse works with Ubuntu 10.10 onwards. Just add the following PPA to your Software Sources:

sudo add-apt-repository ppa:glimpse-hackers/stable

Next step is to run an update and install both glimpse and a profile for your Apps to use:

sudo apt-get update && sudo apt-get install glimpse glimpse-profile-elementary glimpse-profile-ubuntu

Once download launch ‘Glimpse’ from the Dash. In the window that opens click on the ‘Profile’ you wish to use. Depdning on the profile chosen you may need to download or locate an .iso for Glimpse to use.

From there you just hit the ‘Launch Apps’ button to launch an app in Sandboxed mode (such as the ‘Software Centre’ for adding some Unstable PPAs to play with).

Google Music Manager Finally Launches On Linux

Google Music Beta, which was launched back in May, lets users upload as many as 20,000 tracks for free access and streaming through the web and mobile devices – wherever they are in the world.

Music is cached for offline play on both the desktop and mobile devices.

At the time of Music Beta’s launch Google only provided Windows and Mac version of ‘Google Music Manager’ – their desktop client for adding and seamlessly syncing your music folder with Google Music Beta. With the release of Google Music Manager for Linux, everyone* is now free to take advantage of the cloud-music-storage service.

Those of you already signed up/using the service can grab the linux installer – provided as both 32bit and 64bit .deb packages – by hitting the ‘Add Music’ button to the top of the player window.

Download

Music Beta is currently only available in the United States

Ubuntu user and Python developer Jonas Frei sent us an email with a new project he’s working on that’s aimed at making Ubuntu updates easier to access, and consistinify (new word, do you like it?) Update Manager’s presence in the panel.

It notifies you of new updates and gives quick access to the most common commands in Update Manager, including the ability to refresh and install new updates. There’s also a nifty preferences dialog for a bit of customization.

Jonas says of his project:

it’s an indicator which informs the user about available updates (see screenshots). Also, there are some settings that can be made. The applications progress is in a very early stage, though it’s basically functional (at least for me). Some features don’t work yet, like the Autostart function, but work is in progress ;-)

My main motivation to write this program was, that i always found the update-management in Ubuntu rather unsatisfying with the manager just popping up. I preferred how it was done when there was just an icon in the gnome-panel in earlier Ubuntu versions, or like e.g. in Linux Mint. The language I used is C# (I wanted to get into C# and Mono).

Linus Torvalds has announced the release of Linux kernel 3.0 on his Google+ profile after a short delay earlier this week.

So what’s new? Well, not a lot really. The new release sees a few new patches as well as a bit of old cruft removed, but as Linus explains in his announcement to the Linux kernel mailing list in May, 3.0 won’t feature a bunch of new stuff.

So what are the big changes?

NOTHING. Absolutely nothing. Sure, we have the usual two thirds driver changes, and a lot of random fixes, but the point is that 3.0 is *just* about renumbering, we are very much *not* doing a KDE-4 or a Gnome-3 here.

No breakage, no special scary new features, nothing at all like that. We’ve been doing time-based releases for many years now, this is in no way about features. If you want an excuse for the renumbering, you really should look at the time-based one (“20 years”) instead.

here are however a few interesting new tidbits such as a Microsoft Kinect driver, Cleancache support, open source graphics driver improvements including initial support for Intel’s Ivy Bridge, and a lot of changes for the open source Intel, Radeon, and Nouveau drivers.

The new kernel pulls support for a few older, rarely used features such as the Reiser4 file system, and according to Michael Larabel over at Phoronix, unfortunately doesn’t fix the power regressions that were found in Ubuntu 11.04.

Of course Ubuntu 11.10 Oneiric Ocelot will indeed ship with kernel 3.0 stable, but Ubuntu’s Desktop Manager Jason Warner couldn’t say when:

“I don’t know exactly when 3.0 final will get into Oneiric, but it will.”

Ubuntu 11.04 (or Natty Narwhal) or most of the Linux distribution has usually a lower hardware/system requirements as compare to Windows or Mac OS X, and of course Linux based operating systems are more compatible with older hardwares, so in general you don’t need to worry about these minimum hardware specifications and requirements, unless you are using a very old computer. Anyhow, before going to install Ubuntu 11.04 from USB or CD/DVD , you are recommended to check this minimum system requirements.

For Ubuntu 11.04 system requirements may vary depending on the need i.e the purpose for which you are using Ubuntu 11.04. Suppose, if you want to play games (heavy games which requires 3D acceleration..) then of course you would need much RAM as well as a dedicated graphics card such as Nvidia, ATI etc (i.e a separate GPU (Graphics Processing Unit) ), this will be true for similar other jobs which need high graphics capability. If so then get a best graphics card for Ubuntu Desktop.

Ubuntu 11.04/10.10/10.04 System requirements
The system requirements for Ubuntu 11.04 is same as compared to it’s predecessor 10.10 (Maverick Meerkat) or 10.04 (Lucid Lynx), although Unity may not be supported (or it will run with very poor performance, if that’s the case then switch to Gnome and turn off all those fancy desktop effects) in 3D mode on older computer with low graphics capability, in that case it will fall back to Unity in 2D Mode (or to Gnome in older versions of Ubuntu).

Minimum Hardware Requirements

• 
  1 GHz Pentium or better processor (such as Dual Core, Core 2 Duo, i3, i5,i7… )
• 384 MB of primary memory (RAM) although, at-least 512 MB is recommended
• 5 GB of harddrive space but it would be better if you have more than 10GB (unless you are installing Ubuntu 11.04 , for testing or any specific purpose)
• Either a CD/DVD drive or a USB (Universal Serial Bus) port (or both)
• a Graphics Card if you want to use the Unity in 3D Mode, which is the default mode of Ubuntu 11.04, although it’s optional because you can still use Gnome 2.* efficiently by turning off the compiz or desktop effects which consumes a lot of resources
• A monitor (CRT, LCD-TFT, LCD-LED or whatever) capable of displaying output at Resolution (Min) : 800×600
• Internet Connection is not necessary but it’s recommended

That’s All.

A new collaborative robotics project is ripping the idea of autonomous assistance for the disabled out from the land of science-fiction and planting it firmly in the real world – and all using the power of Open Source.

‘Robots for Humanity’ is the result of a team up between Willow Garage, developers of personal robotics hardware and software, ‘Healthcare Robotics Lab’ at Georgia Tech and disabled user Henry Evans and his wife Jane.

Henry Evans was left paralysed by a brain stem stroke at the age of 40. He is unable to move, speak or care fully for himself.

But the Robots for Humanity project is giving him back a small chip of independence.

Ubuntu-D2

Using Ubuntu and a webcam Henry is already able to control his computer, surf the web, write e-mail etc, using simple head movements. Regardless of the OS that is great of itself.

The ‘Robots for Humanity’ project simply extends this idea outwards, letting henry manipulate the world around him via a robot called a PR2.

The Pr2 uses a head-mounted Kinect sensor to monitor Henry’s head movements, and feeds the data back to Henry’s computer to allow him to control the robot, via various interfaces, in real time. Henry can move the robot’s body, arms and head – allowing him to shave, scratch and itch – or use autonomous actions – such as navigating a room or reaching out for an object.

A project such as this should be championed regardless of its nature. But, you know, the fact it’s being built as open-source software, making use of open-source software (all of the promotional videos for Willow Garage show software in use on Ubuntu, no less) is pretty awesome.

You can find out more on the project in the short promotional video below: -

So the long heralded ‘flood’ of ARM netbooks on to the shelves barely even materialised as a drop, with a drop in demand for netbooks and massive growth spurt in touch-screen Tablet devices seemingly diverting attention elsewhere.

PC company Hercules are pinning their hopes on a ‘better late than never’ approach with the launch of a new ARM powered netbook series dubbed the ‘eCafé’.

The eCafé comes in two 10″ flavours:

• A slim white model weighing just 880g
• A heavier black model with 13 hours battery life and HDMI out

Both sport the same internal configuration of: -

• 800Mhz ARM Cortex A8 (Freescale i.MX515)
• 512MB RAM
• 8GB Flash Storage

A chiclet keyboard, 8GB of flash storage, HDMI out, 3 USB ports an, card reader, Headphone/Microphone ports, integrated WiFi, Ethernet port and bizarre touch-controls on the ‘arms’ of the device for controlling media playback round out the specs.

The operating system appears to be a slightly modified version of Ubuntu 10.07 (yes, 10.07) for ARM devices, running the EFL Netbook Launcher.

The eCafe models start from £179 on Amazon UK. (Pre-order)

One of Several Ubuntu Software Centre Designs Proposed for version 5.0

In a recent Ubuntu Desktop Team meeting, where aspects, changes and progess on the Ubuntu desktop are discussed by developers, Software Centre developer Gary Lasker was asked if the new USC design would be ready in time for the release of Ubuntu Alpha 3.

The good news is that the USC in Ubuntu 11.10 will be getting new feature, if not a new look.

The “incumbent” Software Centre is said to work well under GNOME 3.

Loads of good stuff is happening in Ubuntu these days. You can get a good idea of it when you check out the oneiric-changes mailing list. Lots of these changes have been in the making for a bit longer, so expect the ground-breaking changes to happen in the next few weeks. If you’re after the big picture overview: the status overview should give you a very detailed look on how each feature is progressing.

It’s two weeks until Alpha 3 is going to be released and 3 weeks until Feature Freeze, when the majority of the feature work should have landed. If you have updates you want to get into Ubuntu which shake things up, you better get a move on and do it now.

Ubuntu is busy busy busy. On the events front, there was Ubuntu Developer Week last week: around 300 attendees, 25 sessions, all about getting you involved into Ubuntu Development. (Here’s a summary I wrote of the sessions that happened.) Until tomorrow Ubuntu Community Week is happening with great sessions that help you take your local Ubuntu team to the next level. Monday and Tuesday next week (25th-26th July) there will be Ubuntu Cloud Days. Next up will be Ubuntu Global Jam in early September. Awesome, you don’t just get bored in the Ubuntu world! :-D

If you want to get involved in packaging and bug fixing, there’s still a lot of bugs that need to get fixed, particularly packages that fail to build. Also is the Ubuntu Mozilla team looking for help, so if you’re excited about Mozilla and what’s happening there, join IRC, talk to the guys on #ubuntu-mozillateam on irc.freenode.net. And then there’s Security bugs you can take a look at, the team is a friendly bunch and they’re incredibly helpful in getting your patch reviewed.

Since last week we got quite a few new people in the Ubuntu Developer world. This time it’s four people who got their first changes into Ubuntu! Applause everyone! Gal Shalif, Kjetil Kjernsmo, Phil Hagelberg and Vincent Vinet. Good work everyone, rock on!
