New Features in Ubuntu 12.04

Finally Launched!!! Ubuntu 12.04
Ubuntu 12.04 LTS. Canonical's latest is now available in its final(ish) form and ready for you to download, burn and install. While LTS (Long Term Support) releases are generally more conservative in their application of new features, Pangolin does include some rather notable tweaks.

Some New Features in Ubuntu 12.04


The HUD

As hinted by Canonical founder Mark Shuttleworth in late January, Ubuntu's new “Head-Up Display,” or “HUD,” interface makes its debut in this beta version. Dubbed as “a new way to quickly search and access any desktop application’s and indicator’s menu,” HUD can be accessed by pressing the Alt key and typing in a description of what you want to do. The software will then return a set of corresponding entries, including some fuzzy matching, the project team says. Over time, it also learns from your previous choices to make the search more and more accurate, they note.

PRIVACY

The Zeitgeist engine has been integrated in Ubuntu since 11.04. It’s also known as the activity log — it logs things you do on your computer, including files you open, websites you visit, and people you have conversations with. These logs are stored locally and offered to other desktop applications, which can use them to customize your experience.
Responding to privacy concerns, Ubuntu now includes a Privacy panel for managing this behavior. You’ll find it in Ubuntu’s System Settings window.

The Privacy panel includes quite a few options for managing this behavior. In addition to disabling activity recording entirely, you can disable it for certain types of files, folders, or applications. You can also manually delete the activity history — either all of it, or just the history for a recent time period.


Unity Appearance Settings

Ubuntu's Unity interface has been nothing if not controversial, but in this new release, the "Appearance" panel in the software's system settings lets you more easily configure some properties of Unity. For bookmark users, the Unity launcher now also includes Nautilus quicklist support.

 On the Look tab, the size of the application icons on Unity’s launcher are now configurable — you can make them smaller or larger.

On the Behavior tab, you can customize when Unity automatically hides itself. It no longer automatically hides by default, but you can enable the auto-hide feature and tweak its sensitivity, if you like.

Quick Lists

Many more applications now support Unity’s “quicklists” feature, including the Nautilus file manager and Rhythmbox music player. Right-click an application icon on the Unity launcher and you’ll find shortcuts to frequently used options. For example, the Nautilus file manager displays your bookmarked locations, while the Rythmbox music player offers playback options.

Video Lense
Lenses allow you to perform different types of searches directly from Unity’s dash, and Precise Pangolin introduces a new lens for searching videos. Select the video icon at the bottom of the dash screen and you can search for videos stored locally or in a variety of online locations, including YouTube, Vimeo, and TED Talks. Use the Filter Results option to search for videos from a specific location.

 Software Recommendations

The Ubuntu Software Center now offers personalized software recommendations. Click the Turn On Recommendations button at the bottom of the Ubuntu Software Center to enable them. You’ll have to log in with your Ubuntu Software Center account — this is the same as your Ubuntu One or Launchpad account.
When you enable recommendations, your list of installed software will be periodically sent to Canonical’s servers. Recommendations will appear in the Ubuntu Software Center.

 Ubuntu one Redesign

Ubuntu One, Ubuntu’s cloud storage service, has a redesigned interface in Precise Pangolin. Interestingly enough, the new interface uses the QT toolkit (used in KDE). The QT-based interface replaces the old one, which used the same GTK+ toolkit used in GNOME, Unity, and elsewhere on the Ubuntu desktop.

what is 32 -Bit and 64 -Bit

whats the Difference between 32bit and 64bit

What is a Bit ?

In computing, a bit can be defined as a variable or computed quantity that can have only two possible values. These two values are often interpreted as binary digits and are usually denoted by the numerical digits 0 and 1. The two values can also be interpreted as logical values (true/false, yes/no), algebraic signs (+/−), activation states (on/off), or any other two-valued attribute.  OR  The amount of information that can be stored by a digital device or other physical system that can
usually exist in only two distinct states. These may be the two stable positions of an electrical switch, two distinct voltage or current levels allowed by a circuit, two distinct levels of light intensity, two directions of magnetization or polarization, etc. 

What is the difference between 32-bit and 64-bit versions of Windows? 

The terms 32-bit and 64-bit refer to the way a computer's CPU, handles information. The 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than a 32-bit system.

What are the Advantages of a 64bit Processor?

1. More greater performance then 32bit Processor.
2. Allowing for the addressing of more of RAM, 64-bit processing can improve video encoding and decoding, CAD, VMs and some other applications.
3. Ability to address memory amounts over four GB, and up to 16 exabytes

What are the Disadvantages of 64bit Processor?

1. You’re currently not able to take full advantage of the technology because the software vendors haven’t made the switch from 32-bit to 64-bit processors.
2. Most AMD Athlon 64 bit processors are expensive, with prices sure to go down in the future.

Note : You can Still use softwares built for 32bit processor but you cannot use 32bit drivers on 64bit processor
Here's a picture of software built for 32bit that works very well on 64bit , its a preview from task manager

32 bit software working in 64bit PC

All the software of 32bits are marked with a asterisk mark and 32 after it as you can see in the preview

How to Convert VHD to VMDK

VHD and VMDK contains hard disk image which used by virtual machines. VHD is the harddisk image format used by Microsoft virtualization software such as Microsoft Virtual PC, Windows Virtual PC, Microsoft Virtual Server and Microsoft Hyper-V. VHD file format is not compatible with VMDK or Virtual Machine Disk file format used by VMWare virtual appliance products such as VMware Workstation, VMware Player, VMware Server, VMware Fusion or VMware ESX.


a VHD can be converted to VMDK format and used as the hard disk image for VMWare virtual machine. In fact, the virtual machines created in Microsoft virtualization products can be easily converted VMWare virtual machines with VMware vCenter Convertor



VMware vCenter Converter is provided as free download by VMWare to facilitate, automate and simply conversions from physical machine to virtual machine as well as conversions between third-party and VMWare virtual machine image formats. The converter converts and imports supported third-party virtual machine for use on a VMWare product complete with converted .VMX and .VMDK from .VMC and .VHD without further customization. However, VMWare vCenter Converter only does conversion from a virtualization server is installed. Users can’t manually select a VHD file for conversion.


If you only have a VHD file, and want to convert it to VMDK format, WinImage can come to rescue. WinImage is a shareware but available for free evaluation use for up to 30 days. WinImage, which available in both 32-bit (x86) and 64-bit (x64) versions, is available for download from Here

WinImage to convert a VHD to VMDK disk image:

1. Install and run WinImage.
2. Go to Disk in the menu bar and select Convert Virtual Hard Disk Image.

3. An “Open” dialog box will show up. Make sure that the file type selected is Virtual Hard Disk (*.vhd)which should be default selection. Browse to the folder location for the VHD file, select to highlight the VHD, and then click Open.

4. Select either Create Fixed Size Virtual Hard Disk or Create Dynamically Expanding Virtual Hard Disk. You should choose the later for more flexibility if you foresee there will extensive usage on the disk image.

5. On the “Save As” dialog box, change the output format under the Save as Type to VMWare VMDK (*.vmdk). Browse to the folder location which the output disk image to be saved and enter a file name.

Done, Click Save Button

6. WinImage will start the virtual hard disk image conversion process, which may take a while to complete, depending on the size of the virtual hard disk.

7. Once the coversion is done, the VMDK vritual disk is ready for use. WinImage will try to mount the converted virtual disk image in the program after the conversion, where it asks user to select the partition to connect to. 

Click OK if you want to open the virtual disk in WinImage, or Cancel to return to main program.

Once the VMDK virtual disk image is created, the VMDK can be added to existing virtual machine as additional hard disk drive to access its content, or used as existing virtual disk when creating new virtual machine.
