After many years of being a member of the bandwagon to unseat Rhythmbox in favor of Banshee as the default, I end up getting a PS3 and regretting my choice in media player due to the one small gem that is the Coherence plugin for Rhythmbox.
The Coherence plugin allows your Rhythmbox install to act as a UPnP media server on your network. Any UPnP client, such as a PS3 or Logitech Squeezebox device, can then connect to this server and access all of the music from your library.
Many of you may have decent sound systems for your PC already, but for those like myself who don’t, this plugin makes it one-click easy to share music over the network, access it using your favorite entertainment device, and play it directly on your sound system.
To give it a try, simply download the package, open Rhythmbox, and click on Edit -> Plugins to enable it. Please note that as of today, the plugin does NOT appear to work in Oneiric, but I have tested it in Natty and Lucid where it seems to function well. I will be looking into fixing this package before Oneiric launches.
Linux Users Continue To Spend More On Humble Indie Bundle
Linux users continue to pay more for the Humble Indie Bundle 3 than their Windows or OS X counterparts.
With just over one day left to nab eleven awesome DRM-free indie games for whatever price you’re willing to pay, I thought it would be nice to take a quick look at how the Bundle is doing before the last day splurge sets in.
So far the Bundle has amassed over $1.8 million – and should surely tip the $2 million mark by the end of its run this time tomorrow. For comparison the totals for the previous Bundles were as follows: -
Humble Indie Bundle | $1.2 Million
Humble Indie Bundle 2 | $1.8 Million
Humble Frozenbyte Bundle | 700k
Generous Linux folks
Once again Linux users are the most generous of the bunch so far, paying on average $12 for the compendium of titles. To put that $12 into context that’s almost $5 more than Mac users pay are willing to shell out, and over $7 more than what Windows users cough up. Previous Bundles have seen Linux and Mac users making up over 50% of all sales.
Why are Linux folks just so damn generous?
I lack a psychology degree, so I can’t expound on that question any certainty. The nature of sharing, supporting and giving that is so central to the Open-Source ethos, mixed in with a desire to thank and support developers who go out of their way to support them, are likely to be strong motives behind the support.
That and paying for software is a bit of a novelty ;)
Extra Titles Extra titles have been added to Bundle 3 since its launch a week ago, making a total of 12 games (plus a free trial of Minecraft) are now on offer to anyone paying more than the ‘average price’ of $5.71.
Crayon Physics Deluxe – Physics based puzzle game
Cogs – Steampunk themed puzzle game
VVVVVV – Retro-themed platformer with insane gravity element
Hammerfight - weapon-based melee ‘smash ‘em up’
And Yet It Moves – Beauitful and award winning physics platformer
Steel Storm - Top down action shooter
Atom Zombie Smasher – RTS game, zombie-style
Braid - Critically-acclaimed puzzle game
Cortex Command – 2D side-scroller
Machinarium – Visually stunning point-and-click puzzle game
Osmos – Single player puzzle game
Revenge of the Titans – RTS game
If you purchased your bundle before the extra games were added fear not – just head to your ‘Download’ area (sent via e-mail when you purchased the bundle) to download them.
Over the last week we’ve heard from a number of our readers in India, the territory in which the ad is shown, that a new version of the advert is showing with the only perceivable difference being the removal of the Ubuntu logo from the beginning of the advert.
Anecdotally, Samsung also removed the ‘Ubuntu’ version of the advert from YouTube.
Reader Juan Carlos Arroyo Callejas sent us his guide on getting a “clean looking Natty desktop”, which he dutifully shows off in the image below:
Only attempt to follow Juan’s guide if you are certain you want the look. To revert the changes you will need to work backwards reverting the steps (install instead of remove, true instead of false, etc.)
REMOVE FILES AND PLACES FROM UNITY LAUNCHER
sudo gedit /usr/share/unity/places/*.place
ADD THIS LINE BELOW “Shortcut=” IN BOTH TABS:
REMOVE WORKSPACES (EXPO) FROM UNITY LAUNCHER
Run gnome-panel via terminal, and in workspaces make them all vertical
Close the terminal, log out log in voilà. As a bug, the WORKSPACE icon disappears.
Access and Add Files On Your ASUS Transformer in Ubuntu
gMTP can be installed through the Ubuntu Software Centre (click) and provides a simple interface for browsing through files and folders on your Transformer. To add files from your PC to your tablet you simple drag and drop them into the folder you wish to store them in.
Drawbacks include an inability to ‘download’ files from my Transformer to my desktop and no extra ‘views’ for the file browser such as ‘thumbnails’ to make identifying photos easier.
MTPFS is “…a FUSE filesystem that supports reading and writing from any MTP device.” It’s not a standalone programme like gMTP above. Instead MTPFS gives you access to your Transformer files via Nautilus, allowing you to browse them just like any other folder on your desktop.
The main drawback is ‘mounting’ it. One needs to jump through a few hoops to get it set up. If you’re prepared to, and this is certainly my preferred method for now, instructions follow.
Open a terminal and run the following commands separately, entering your password where prompted. Ensure your Transformer is connected via USB to your computer.
sudo apt-get install mtpfs
sudo mkdir /media/transformer
sudo chmod 775 /media/transformer
To “mount” your transformer so you can access, add and download files run: -
sudo mtpfs -o allow_other /media/transformer
When done run:
sudo umount mtpfs
You will need to repeat the last two steps every time you wish to mount then unmount your device. Admittedly this method is less than elegant but it does work. Using it I can browse my Transformer using Nautilus, including seeing thumbnails of photos, previews of music tracks by hovering over them, etc.
Some versions of Ubuntu don’t automatically give you the option to upgrade to the latest version. In this week’s Ubuntu is Easy segment, I show you the easy way to upgrade Ubuntu to the latest release, which as of when this video was released is 11.04, Natty Narwhal!
Video produced on Linux Mint 10 using Kdenlive, Audacity, and GIMP.
Deadline.com are reporting that Disney have hired Night At The Museum writer Robert Ben Garant to pen an animated feature about a talking Penguin called, you guessed it, ‘Tux’.
The film is to be an adaptation of “gritty” Japanese graphic novel ‘Tuxedo Gin’, the storyline of which sees a young street fighter “fall into a coma and learns that he …only has enough karma points to be reincarnated as an animal 15 pounds or less.”
That animal is a penguin.
For those unaware of why this is slightly humorous the Linux mascot, Tux, is a penguin. Here’s hoping for a Linux in joke somewhere ;)
Ubuntu One Upgrades Free Storage to 5GB, Hits 1 Million Users
The upgrade will be applied to all user accounts on the basic plan, which has been renamed ‘Ubuntu One Free’.
Subscribers to the Ubuntu One Music service will also benefit from an upgrade, with the base storage bumped up to 20GB for $3.99/month. Additional storage, available in 20GB blocks, are available forn $2.99.
The news that Ubuntu One reached the one million user milestone back in May this year was also announced.
Ubuntu One App Developer Program
The Ubuntu One App DeveloperProgram has also been made public. This ‘hub’ of information provides developers eager to integrate Ubuntu One feature into their applications with the relevant documentation, further information, links and more.
One that caught our eye was ‘In The Dark’ by Escapement Studios.
Like a lot of indie games produced recently ‘In The Dark’ is a 2D puzzle-platformer boasting a unique gameplay concept involving light and shadows.
“…we designed a world in which imagination could take over where your childhood left off – a world in which monsters exist, lurking within the shadows, threatening to snatch you up the moment you leave the safety and comfort of the light.”
The game is built on a modified version of LÖVE – the game engine that powers our very own ‘Volleybrawl’.
Money will be used to ‘fund artists so they can take time away from their normal paying jobs to make any more progress on the game.’
The game will be commercially available on Linux, Windows and Mac OS in early 2012. Ports for iOS and Android are also on the cards.
Facebook is only seven years old and has only been open to non-college students for five years (kids under 13 are not offiially allowed to join), so researchers have not had much time to study the emotional, physical, and psychological effects it could have on kids. But science has proven at least one thing: Facebook does something to some people’s brains, probably.
Antivirus software for Ubuntu Users – is it optional ?
Ubuntu 11.04 (Natty Narwhal) or 11.10 (Few alpha versions has arrived, the stable will be released after few months) or 10.10 or any Linux based distributions are very less prone to virus attacks or malwares, spywares (or any similar *wares). The reason is pretty straight forward – First Linux based operating systems are highly secure and the second reason is that Microsoft Windows (XP, Vista, 7 ..) has been the targeted systems for crackers / hackers or malicious programmers (may be due to the fact that most of the common users uses Microsoft Windows operating system).
Therefore, in general, you don’t need to install any antivirus software on Ubuntu; it’s OK!
Avast for Ubuntu 11.04/10.10/11.10..
For ubuntu there is another antivirus software called – ClamAV, a simple and effective antivirus application. Avast is a antivirus software program based on central scanning engine (ICSA Lab certified), although it is a proprietary software but the ‘Linux Home Edition’ is available for personal and non commercial uses (Pro version provides extended functionality and features (e.g Command Line Scanner) for some price), free of cost.
Anyway, if you want to try Avast then you need to download the debian package and install it – either from command line or using Ubuntu Software Center.
step 2 : Install the *.deb package by Right Click -> Open with Ubuntu Software Center, and click on install button and relax! or just enter the following command -
sudo dpkg -i file_name.deb
step 3 : To start using avast antivirus software, You need to Register with avast to get a free license key (Don’t worry it’s free!). The license key will be delivered to your email address within 24 hours (usually withing a couple of hours).
step 4 : Start the program and enter the license key. That’s all!
Unified Modelling Language (UML) is basically a modelling languages that is typically used in the design phase of object oriented software development process, to express the thought in graphical representation, to visualize the system etc. UML, created by OMG (Object Management Group), has now become the standard approach to software modelling. In fact the UML diagrams makes coding part easier in complex systems, so the time you would spent in drawing will save you a lot of time (later, during development/implementation phase). UML diagrams represents – Static as well as Dynamic views of a system, so using UML tools you can draw – class diagrams, activity diagrams, sequence diagrams, use case diagrams etc.
There are various tools available such as IBM Rational Rose, for drawing UML diagrams but in this post you are going to know about some open source modelling tools, that you can use on your Linux based Operating systems e.g Ubuntu 11.04 (Natty Narwhal) /11.10 (Oneiric Ocelot, the code name of upcoming version)/ or older versions such as 10.10/10.04 LTS…, Linux Mint, Fedora, OpenSuse etc.
Umbrello UML Modeller
Umbrello is a KDE based software for creating UML diagrams in standard format. It supports a lot of languages and code generation (advanced code generation is available for ruby) is also supported, it has all basic features – that you expect from a UML tool.
sudo apt-get install umbrello
Gaphor is a cross-platform UML tool with simplicity, before installing it be sure to check for its dependencies such as Python (version 2.5 or later).
Kind of. Fusion Blue steers clear of bold blue, opting for a more sedate ‘aquamarine’ affair. In places, such as the Unity panel, it can sometimes appear metallic.
In my opinion the theme is let down by the poor choice of complimentary colour: a Windows 95-style grey that gives the theme a “WIP” look; almost like the colour has yet to be decided for the rest of it.
Things to note: -
Requires use of modded Faenza icon pack
Window controls are placed to the right
Things to love: -
Comes with a Unity panel theme
Things that could be better: -
The grey used throughout the theme is very ‘Windows 95‘
Web-browser Midori Adds Unity Support and Neat ‘Next Page’ Feature,
Unity support is one of several changes making up the latest release of lightweight web browser Midori.
Midori 0.4.0: Notable Changes
We’ll begin this run down with the one part of Midori you probably see more than you care to: the crash dialog.
In Midori 0.4.0 this has received a birrova overhaul, with nicely placed options for ‘discarding, loading or delaying’ your last open tabs placed along the bottom.
Navigating to ‘the next page’ on Google search (not that anyone goes past page 1 ;)), Forums and other sites with a ‘next’ link is a breeze in this update: just hit the space bar. Alternatively you’re free to press the ‘Forward’ button now present in the taskbar.
Installing Midori 0.4.0 in Ubuntu 10.04 through 11.04
Midori is available to install in Ubuntu 10.04 through 11.04 Natty Narwhal via the official Midori PPA. In order to use this PPA you also have to add the webkit team PPA.
Both can be added in Ubuntu by running the following command via a Terminal: -
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
Checking out the “Accessories” available for installation: -
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.
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.
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):
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.
Download and install the Facebook Applet for Unity
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: -
Authorise the application with Facebook
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 -
JDK (Java Development Kit)
How to Install and Configure Android SDK with Eclipse IDE
Now, you can install Android in two simple steps :
step #1 : Download and install the android package(s).
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 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)
step #2 : Install and configure the ADT (Android Development Tool) plugin
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.
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)
‘Glimpse’ for Linux Offers Safe Sandbox Testing of Unstable Apps
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.”
Glimpse works with Ubuntu 10.10 onwards. Just add the following PPA to your Software Sources:
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 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.
Update Manager Indicator puts Ubuntu updates in your panel
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 announces stable release of Linux kernel 3.0
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
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.
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: -
‘eCAFÉ’ ARM Netbook Runs Ubuntu, Boasts 13 Hours of Battery Life
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)
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)
The third maintenance update to Ubuntu 10.04.3 LTS has been released.
Ubuntu 10.04 LTS, released in April of 2010, will continue to be supported with updates and security fixes until April 2013 on desktops and April 2015 on servers.
In announcing the release of 10.04.3 Canonical’s Kate Stewart explained what the update contains:
Numerous updates have been integrated, and updated installation media have been provided so that fewer updates will need to be downloaded after installation. These include security updates and corrections for other high-impact bugs, with a focus on maintaining stability and compatibility with Ubuntu 10.04 LTS.
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!
An update to the indicator menus this weekend saw the ‘Me Menu’ (‘indicator-me‘) removed and replaced with an ‘IM Status’ section in the Messaging Menu.
Why has it gone? Due to changes elsewhere in Ubuntu the Me Menu had become largely redundant, not least of which is the ‘System Settings’ panel now housing user account settings.
Moving the ‘Status Session’ to the Messaging Menu is also a logical move. Writing on the Messaging Menu wiki page Ubuntu’s Matthew Paul Thomas explains the rationale:
The messaging menu aims to make communication easier with other people. It does this first by letting you set IM status quickly and across messaging applications; and secondly by providing quick access to messages, concerning you, that you may not have seen
The Messaging Menu is structured to have ‘Status’ section at the top, following by ‘Application’ sections (Empathy, Gwibber, Thunderbird, etc.) followed by two new menu entries: -
‘Clear Items’ – This option removes ‘attention’ from the Messaging Menu by resetting the Messaging Menu panel icons to the default look. Message counts, times, etc. remain visible in the Menu.
'Hide This Menu’ – clicking this launches an alert box “explaining the purpose of the menu, and how you can get it back if you change your mind.”
To help tide us over until Google release official Google+ tools for developers to play with reader Tom LeJeune has added ‘drag n’ drop’ Picasa image uploading to the Google+ Unity Launcher Quicklist we featured recently.
Installing GoogleCL in Ubuntu The first step is to install ‘googlecl‘ – a set of neat command line tools provided by Google for accessing their various services. GoogleCL is available through the Ubuntu Software Centre, so either search for it manually or hit the button below to launch and proceed.
After installing GoogleCL you’ll need to authorize your Picasa account with it.
Type ‘google picasa list‘
Enter your username (firstname.lastname@example.org)
Your browser will launch, taking you to an authorization page.
Agree/accept/allow access to GoogleCL
Return to the Terminal window and be patient: it can sometimes take a good few minutes for GoogleCL to receive instructions.
Adding Google+ Picasa Uploader to Unity Launcher
With the preparation out of the way we can move on to adding and installing the Google+ launcher.
Download the Google+ Unity Launcher package by pressing the button below.
PDF (Portable Document Format, an open standard for exchanging documents, developed by adobe systems in 1993) Reader are softwares or applications that allow users to view the PDF documents, e.g Adobe PDF Reader, Foxit Reader etc. On Ubuntu 11.04 (Natty Narwhal) /10.10 (Maverick Meerkat) /10.04 (Lucid Lynx) ..or other Linux based operating such as Linux Mint has one applications installed by default – called Document Viewer – which is good for reading PDF documents.
But there are some other PDF readers available free of cost, with some advanced features and you would like to try that on Ubuntu, this post explains about all the most popular pdf readers available for Ubuntu users. Some of them are open source while others might be a freeware applications but all works well with Ubuntu.
Evince Document Viewer Evince is a ‘Document Viewer’ application installed by default on Ubuntu or other Linux distributions. It is a fast application with a lot of useful features such as Index, Thumbnails etc. it’s a free and open source software that is shipped with most of the Linux distributions which is based on Gnome. To view a document using Document Viewer, just double click on the PDF file.
File Formats supported with Evince
xps (XML Paper Specification)
cbr, cbz, cb7 and cbt (comic books formats)
Adobe Reader Adobe Reader or Acrobat Reader is one of the most popular PDF viewer. It’s standard version is available free (as freeware application). it’s very simple to use and the interface is also very good. it has a lot of features which can be further extended to the professional level by purchasing the Pro or Suite (it includes PDF readers as well as necessary softwares and tools for creating and editing professional quality documents) version of the application.
Foxit Reader is a free software provided by Foxit Corporation. Both basic and full version are available free to use, for all platforms. The Linux version of the Foxit reader doesn’t have so much features as compared to the windows version but still it’s good, specifically if you have used it on Windows platforms (Xp, Vista or 7). It has lot of good features such as support for multi language, short load time and speed (it’s fast as compared to other pdf readers but it may not be true on Ubuntu or other Linux based OS).
What is OpenDNS ? OpenDNS is a DNS (Domain Name Resolution, it’s basically a naming system which maps human friendly domain name (e.g sudobits.com) to I.P (Internet Protocol) address e.g 188.8.131.52 ). Each time ( if it’s not cached ) when you visit a website, your browser sends a DNS lookup query to the DNS server, most probably to your ISP DNS but you can configure your computer to use some other DNS servers such as OpenDNS for name resolution purposes, if you want. So in the end of this post you will learn how to use OpenDNS on your Ubuntu 11.04 (Natty Narwhal) or 10.10 (Maverick Meerkat) or 10.04 (Lucid Lynx) or any other Linux based operating systems such as Linux Mint, Fedora, Debian etc (Procedure is almost same).
A typical ISP (Internet Service Provider) DNS server works well in general but there are few extra advantages with OpenDNS, some of the important features are :
Open DNS is very fast (may not be true for non US users e.g if an Indian users will use OpenDNS instead of the BSNL DNS server, then it will be slow because BSNL DNS servers usually takes 400ms to resolve an I.P address while OpenDNS would take more than 1000ms due to high latency)
It protects you from the phishing attacks
Content filtering features are also available which can be used to block unwanted sites
it’s free for personal use
Setup OpenDNS on Ubuntu 11.04/10.10/10.04 in few simple steps
#1 : Right Click on Network icon -> Edit Connections.
#2 : Then click on Add button to add a network or exist the existing one (Auto eth0) but it’s better to give configure a new one so that you can use both DNS depending on the need.
#3 : Next, click on IPv4 settings and select “Automatic (DHCP) Address only” (DHCP ( Dynamic Host Configuration Protocol) servers are used to allocate I.P address(usually Dynamic I.P Address) to the users) in Method. You can check the box if you want to connect automatically when your computer starts, better leave it uncheck. Give it a human friendly name e.g ‘OpenDNS’.
In ‘DNS servers’ field put these I.P Addresses : 184.108.40.206,220.127.116.11
You shouldn’t waste a lot of system resources by keeping the computer in ‘on mode’ even though you aren’t using it ( Save Energy! ), should you? ( I hope your answer will be NO, ‘ for the sake of Humanity ‘ ). In some cases Auto shutdown command may help you a lot because it will automatically shutdown your computer at specific time (and of course you can use that command to shutdown your computer immediately from the terminal) and you can cancel the command in the mid time (I mean – before the scheduled time) if you want.
I often use this command, later I thought it might help you in saving a lot of valuable computing resources and energy. Since it is some kind of command – so if you think that ‘I may have to mess with Terminal or Linux shell’ then you need to relax! it’s one of the most simple command and you can learn it in few seconds. It doesn’t matter whether you are using Ubuntu 11.04 (Natty Narwhal) or 10.10 (Maverick Meerkat) or 10.04 (Lucid Lynx) or any other Linux based systems such as Linux Mint.
Auto Shutdown Command in Ubuntu 11.04/10.10/10.04
Open Terminal(CTRL+ALT+T). To shutdown the computer at specific Time use (You may have to authenticate yourself by entering your ubuntu login password) -
Are you looking for Notepad on Ubuntu 11.04 (Natty Narwhal) or 10.10 (Maverick Meerkat) or 10.04 (Lucid Lynx) or any Linux based system ? it seems that you are (or probably you were) a window user and searching for a text editor such as Notepad. Sorry to say – Notepad is a windows NT based application which is available for windows only, so there is no chance on Ubuntu 11.04 or whatever. But my question is “why are you searching for notepad, on Ubuntu?”, the obvious answer would be – just for creating or editing a simple text file. Oh! that’s what you want; Relax, on Ubuntu there is a text editor called – ‘gedit’ (installed by default) – one of the most powerful text editor on this planet.
So I recommend gedit for text editing or source code editing or whatever you wanted to do with notepad – it’s there in gedit; in fact gedit is far better than the notepad (better read this post – ‘best text editor for ubuntu users‘ to understand few great features (syntax coloring, auto completion..) of gedit). But anyway, if you desperately need notepad (I don’t no why? may be just for Fun! because I don’t see any rational reason behind this) on Ubuntu then you need to install ‘Wine’ a windows compatibility layer (developed using reverse engineering) which will allow you to run some windows applications on Ubuntu or Linux based distributions.
Installing Notepad on Ubuntu 11.04/10.10 : using Wine
Open Terminal (hit CTRL+ALT+T ) and type (to install wine as well as some basic apps such as notepad):
Welcome to another installment of the Unity progress report. Many Unity team members are recovering from the Dublin sprint, however the polish is still is still trickling in. Thanks for the great fixes Rafał, Andrea, Daniel and Oliver! Also a reminder that we have an IRC meeting today at 1800UTC on #ayatana on Freenode if you’d like to get started hacking on Unity.
Unity Contributor Activity This Week
Rafał Cieślak shows his appreciation to detail by adjusting the distance between application indicators (not applications menus) since they were too apart from each other. The spacing was decreased as a fix to bug #684114 but now has been increased by 1px for a more consistent look.
Rafał also fixes an annoyance where the window title switches to the menu, when hovering over the window buttons in the top panel. This can be a bit distracting indeed, since you would like to act on the window, and not with its menu. Luckily this is no longer the case.
Andrea Azzarone does some pretty rocking work as well! Andrea’s commit unmounts/ejects an USB-stick by dragging it to the trash-icon on the launcher. This also spawns a notification to inform the use of the succeeded operation. I really like this one, thanks Andrea!.
Andrea also fixes another bug that eliminates unneeded disk-I/O while dragging a launcher-icon to a new position. Less disk I/O is always welcome!
Andrea also blows away 5 memory leaks as uncovered by valgrind and fixes a memory leak in the panel indicator. This improves the stability of the panel as well as memory consumption.
Daniel van Vugt works on some fit and finish where on mouse-over the highlight background square is now correctly aligned even for smaller icons such as Thunderbird.
Oliver Sauder improves the run dialog (the alt+f2) dialog, such that it always opens up showing the most used commands, and not start up blank the first time after reboot. This helps provide a more consistent experience, thanks Oliver for the fix.
