VideoCacheView

Sometimes you might find some interesting videos from web sites and you want to save them into your local disk for replay when you go offline or share with others in the future. Some websites allow you to download and save the videos while others disallow it. If the video you play from the website is stored in your browser’s cache, a tiny and free utility, VideoCacheView, can give you a hand.

VideoCacheView is a standalone program which can help users to extract the video file from the browser cache and save it for viewing in the future. Users can execute the file without installing it. The program will automatically scan the entire cache of your web browsers (supports both Internet Explorer and Mozilla Firefox and Chrome) and detect all videos that are currently available under each browser's cache.











Users can thence choose to play back the video or download/copy it to the local disk.
After the video list is displayed, you can use one of the following options, assuming that the video files are stored in the cache :

* Play Selected File: Allows you to play the video file directly from the cache, assuming that you have a video player that is configured to play .flv files.
* Copy Selected Files To: Allows to copy the video files from the cache into another folder, so you will be able to play them in the future.











Generally most websites use Flash video files (with the .flv extension) for playing video materials inside the website. VideoCacheView itself is not a video player, hence users need to have a video player which support flv format to replay the video.real player is suitable to play flv format files.you can download it through this link. Alternately users need to use a converter to convert Flash video files to other formats such as mpg.

Michael -The Unique Icon

This is a tribute to late POP king Michael Jackson
I am not posting this blogpost if he is not a Unique man.i had enjoyed his songs and his unique dancing style since my childhood.that's what i am spending my blog space for him.

Think about the generations and to say we want to make it a better
world for our children and our children's children. So that they know
it's a better world for them; and think if they can make it a better
place.

There's a place in your heart
And I know that it is love
And this place could be much
Brighter than tomorrow.
And if you really try
You'll find there's no need to cry
In this place you'll feel
There's no hurt or sorrow.
There are ways to get there
If you care enough for the living
Make a little space, make a better place.


Heal The World

SixthSense

We've evolved over millions of years to sense the world around us. When we encounter something, someone or some place, we use our five natural senses to perceive information about it; that information helps us make decisions and chose the right actions to take. But arguably the most useful information that can help us make the right decision is not naturally perceivable with our five senses, namely the data, information and knowledge that mankind has accumulated about everything and which is increasingly all available online. Although the miniaturization of computing devices allows us to carry computers in our pockets, keeping us continually connected to the digital world, there is no link between our digital devices and our interactions with the physical world. Information is confined traditionally on paper or digitally on a screen. SixthSense bridges this gap, bringing intangible, digital information out into the tangible world, and allowing us to interact with this information via natural hand gestures. ‘SixthSense’ frees information from its confines by seamlessly integrating it with reality, and thus making the entire world your computer.

"'SixthSense' is a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information."



The SixthSense prototype is comprised of a pocket projector, a mirror and a camera. The hardware components are coupled in a pendant like mobile wearable device. Both the projector and the camera are connected to the mobile computing device in the user’s pocket. The projector projects visual information enabling surfaces, walls and physical objects around us to be used as interfaces; while the camera recognizes and tracks user's hand gestures and physical objects using computer-vision based techniques. The software program processes the video stream data captured by the camera and tracks the locations of the colored markers (visual tracking fiducials) at the tip of the user’s fingers using simple computer-vision techniques. The movements and arrangements of these fiducials are interpreted into gestures that act as interaction instructions for the projected application interfaces. The maximum number of tracked fingers is only constrained by the number of unique fiducials, thus SixthSense also supports multi-touch and multi-user interaction.



The SixthSense prototype implements several applications that demonstrate the usefulness, viability and flexibility of the system. The map application lets the user navigate a map displayed on a nearby surface using hand gestures, similar to gestures supported by Multi-Touch based systems, letting the user zoom in, zoom out or pan using intuitive hand movements. The drawing application lets the user draw on any surface by tracking the fingertip movements of the user’s index finger. SixthSense also recognizes user’s freehand gestures (postures). For example, the SixthSense system implements a gestural camera that takes photos of the scene the user is looking at by detecting the ‘framing’ gesture. The user can stop by any surface or wall and flick through the photos he/she has taken. SixthSense also lets the user draw icons or symbols in the air using the movement of the index finger and recognizes those symbols as interaction instructions. For example, drawing a magnifying glass symbol takes the user to the map application or drawing an ‘@’ symbol lets the user check his mail. The SixthSense system also augments physical objects the user is interacting with by projecting more information about these objects projected on them. For example, a newspaper can show live video news or dynamic information can be provided on a regular piece of paper. The gesture of drawing a circle on the user’s wrist projects an analog watch.

The current prototype system costs approximate $350 to build.

Ubuntu - "Humanity to others"

Ubuntu is an ancient African word that mean "Humanity to others".Ubuntu is a free linux distribution that bring the spirit of Ubuntu meaning to the software world.

I got Ubuntu 9.04 Desktop Edition it's amazing WOW it has fascinating GUI and it's better than Fedora 10.i am personally tried and tired on Fedora 9 and Fedora 10 version it needs 3.4 GB (3662573568 bytes) disk space that is probably a 5 CDs and equal to 1 DVD space.

Fedora 9 & 10 still not supporting VIA Chrome9 HC IGP Family VGA adapter.during installation process Anaconda detect VGA chip-set but X-windows system will not be able to support VIA Chrome9 HC IGP Family chip-set.if you have Motherboard with VIA Chrome9 HC IGP Family chip-set just giveup Fedora 9 or 10 installation unless you will be ended with Balck screen that is nothing will be appreared.but Ubuntu compatible with VIA Chrome9 HC IGP Family chip-set.

Ubuntu 9.04 has on the fly media mounting facility (your existing windows partition can read by single click.you can share files between Windows and Ubuntu) it's brilliant and quick.i personally tried it on my vmWare 6.5 virtual machine and on my personal computer.

Ubuntu 9.04 Desktop Edition supporting various sound format and vedio format if you get dry with lack of media format/codec to run various sound and vedio format you can just simply and freely download any kind of media format through Ubuntu community.Ubuntu 9.04 is supporting you 18 month updates subscriptions.

you don't have to waste your time for searching codec or something else.you just want to click on unsupported file and Ubuntu will search on net if it's unsupported and definitely will get you back a supported codec or plugging for your needs.

flv,mpeg,mpg,mov,mp3 any format will freely supported under the Ubuntu 9.04.

all above things is pros in Ubuntu but the cons is you need better Internet connection to download extra pluggings.it's 1000 worth to Sri lankan students and even developers or normal housewife to get rid of Windows fever.

Another useful thing is these all in one Ubuntu 9.04 i386 has totaling 698.3 MB single CD.no need to burn any more DVDs or pack of CDs for Linux distribution.

Flush-out the Windows from Sri lankan society and promote the open source software is better to all Sri lankan.

Microsoft allowed to promote Windows about 10 years in Sri lanka among the sri lankan society.still Windows in every IT blood cells in Sri lanka.we need to change this.
now Microsoft established in Sri lanka as Microsoft Srilanka.

Microsoft pushed Sri lankan government to put forward Software Piracy and Privacy legal Act.now anyone can't get a copy of Microsoft product for 100 rupees from unity plaza(famous pirated copy distribution center in colombo).

but any normal Sri lankan student or person can't get a original copy of Microsoft Windows and Office packages since price is too high it's vary from $99.95 to $319.95 without shipping and handling charges.it's about approximately 11394.30 Rs to 36474.30 Rs in Sri lankan rupees.

Sri lankan rural society still can't hold Microsoft's price volume for their Products.that's why we need to change the Microsoft paradigm to Open source Linux paradigm.

How to Uninstall/Remove Linux from Dualboot system

Are you tired with Un-install/Remove Linux(RedHat,Fedora) or Ubuntu, or any other linux distribution from your dual boot system?

sometimes you will be getting serious trouble If you removed linux partition directly from you existing dual boot(windows+linux) system and your existing windows boot screen will past away.you will not be able to access any windows partition in normal condition.otherwise linux GRUB or LILO boot loaders will still remain although you entirely deleted linux partitions.

Why is that happened ?

1st Note :
when you installing linux distro with windows system(windows first installed).linux setup will ask you to put boot loader record on your MBR (Master Boot Record) or first sector of boot partition(that mean your VBR-volume boot record).you can decide which is suitable to put your boot loader record on.

Most people don't know what's the different between MBR and first sector of boot partition.

MBR is differ from first sector of boot partion(sometimes reffer as volume boot record).MBR acting on entire hard disk while VBR acting only for partition.each partition should have their own VBR but active partition will maintain the active VBR others are remaining as incative but not deleted.VBR using the same concept to record details as MBR using.

it is good to record/write down that where your boot loader record was put.it's for your feature needs.

2nd Note :
if you selected the place where is suitable to put your boot loader record. then Linux will modify your existing MBR or first sector of boot partition(VBR) for attaching GRUB or LILO boot loader with your existing NTRLD windows boot loader.then Linux will create a new boot loader record for booting process.

when you deleting the linux partition, your modified MRB will still remain as untouched that mean boot loader record on the MBR will have GRUB or LILO loaders.your original MBR that was there during the windows installation process will not be recovered.that is why you may see GRUB or LILO boot loaders during PC boot even if you deleted linux partions.but default windows NTLDR boot loader also still remain as untouched and hence you can still boot windows by selecting windows entry in GRUB or LILO boot loader.

this will happen since you selected MBR as a place for boot loader record(boot loader) during advance boot loader configuaration phase in linux installation.

Legend solution to this problem :

Insert an XP installation CD and enter setup mode. Choose the recovery option and boot to the DOS command line. Execute the command "FIXMBR" and reboot. The "FIXMBR" command re-initializes the MBR with NTLDR.
The GRUB or LILO(select Os) screen no longer appears and the PC boots straight into windows. The linux partitions appear in XP disk manager as
"unknown. Use Disk manager to reformat the linux partitions as NTFS and assign a drive letter.

But above solution is not safe and it's can't be expected as always working.since if you selected first sector of boot partition(VBR) for placing boot loader record then "FIXMBR" is not deal with VBR, that is the reason.

Latest solution to this problem :

The answer is simple tool it's BootIt NG from http://www.terabyteunlimited.com

you don't need to buy it just download from their link and it will be a zip file (bootitng.zip) and then extract it to proper location and go to the location where you extracted files.

Step 1. Double click on BOOTITNG.EXE file and this window will be appeared.

Step 2 . you must accept the license aggrement by typing "y" in prompt.next windows will ask you to create BootIt NG installation diskette/ISO image.

you must select either one of two option to create bootable floppy disk or bootable CD.if you select "Build a Bootable ISO image file for CD" option then it will create BOOTITNG.ISO file.you need to burn it to CD by using ISO burning software (such as Nero).both bootable floppy and CD contain the same program. after creating your bootable disk your can use it to boot your PC.

Step 3. Next you will restart your computer with the CD or floppy in the drive. Once you boot into the program you will be asked to install BootIt NG to your Hard disk.just click cancel to just run it on the CD or floppy.do not install it to your HDD.when you restarted PC this window will be appeared to you.

It has more advance functions you must follow the every instruction in BootIt NG documentation pdf.

Step 4. then go to partition work icon in desktop just double click. it will get window like this.

Step 5. Click the Option buttion on the left side of the window to select to your primary hdd.

Select and delete every (Linux distro) partitions except your standard windows partition.

Now you should have a formatless/Unallocated partition that says free space after it.

Step 6. Next, you need to fix installed GRUB/LILO bootloader that is on your MBR.It will need to reset your MBR or else you can't boot up or GRUB will still remain as before.

Step 7. To do this select you Windows partition go to View MBR button and click on it in the left pannel. When in there select your windows partion and click Std MBR.

Std MBR is equivalent to fdisk/mbr which creates the small program to boot the active partition.

This will take GRUB off and set your MBR back to the way it was before. Click Apply and the changes will be made.

Step 8. Then eject your media and use the file menu at the top left corner to reboot. Your computer should restart normally into Windows.

My Advice
Before using BootIt NG on any system for the first time, back up all data on all hard drives. It’s better to be safe than sorry.
