Thank you . . .


Thank you . .

Rule number one : don’t screw around with the browser of your enduser. Say that you were able to filter out the print menu item. What about the keyboard combination ctrl + P? You could override that again with some javascript but that only leaves the enduser clueless as you’re overriding standard functionality and that’s a big nono.

Besides that, you’re using javascript. That can be turned off by an enduser and then your clipboard erasing script also doesn’t work anymore. Poof and there goes your protection level.

try it . .

Thank you

for firefox try as below:

Zenpad 7 : Android tablet for Rs. 13,999

H T Impex, which usually sells computer peripherals under the brand name “Zen the Master” has entered the tablet segment with Zenpad 7. The tablet costs Rs. 13999, runs Android 2.1 and comes with 8 GB memory card. Zenpad 7 joins ten odd Android tablets which are already launched in India.


Zenpad 7 has a 1 GHz processor, 256 MB RAM and runs Android 2.1 (Eclair). There is USB port onboard. HDMI port is available and the package comes with the HDMI cable which is useful to connect to TV.

Zenpad 7 has a 7-inch resistive touch screen with 800×480 pixel resolution. There is a 0.3 megapixel VGA camera, speakers, video recording and Wi-Fi.



1 GHz processor on Zenpad is one of the fastest available on the current crop of tablets. HDMI out is another added attraction which is generally not found in tablets in this price range.


Zenpad 7 isn’t 3G enabled and it doesn’t have Bluetooth (at least from the specs available). It has a 0.3 megapixel VGA camera which is not of much value. Cheaper cell phones have digital cameras. Though higher megapixel camera doesn’t necessarily mean better pictures, a VGA camera is not in vogue.

Resistive touch screen is difficult to operate. I did not have much luck with resistive touch screen. It depends on how responsive the touch screen on Zenpad is. May be it should be sold with a stylus.


At the price point of Rs.13999, it is competing with Infibeam Phi. Every other tablet launched in India are either priced below 10K or above 20K and 30K. It is not fair to compare Zenpad 7 against an Olivepad or Samsung Galaxy Tab.

Comparing Zenpad 7 with Infibeam Phi, Zenpad has better specs. Infibeam has 600 MHz processor and no camera or video out. Zenpad has a faster processor, 0.3 megapixel camera ( though this is not of much value) and HDMI out.

For the similar money though, if someone can bring it to you from the US, Nook Color ($250) looks like a better buy. Though unjust comparison, Nook Color has a capacitive touch screen and is a perfect eReading device – if that’s your intention.

If you can’t get a Nook Color, Zenpad 7 is a decent buy.


Intel Core i7 vs Intel Core 2 Duo – The Difference

With the launch of the new Core i7 (Nehalem) processors by Intel, there are many doubts regarding the Difference between Intel Core i7 and Intel Core 2 Duo and Core 2 Quad processors. In this post, I will try to list all the differences and also reasons why the new Core i7 architecture is much better than the Core 2 architecture.

Intel Core i7

Codenamed: Bloomfield – Nehalem
Fabrication: 45 nm
Instruction set: X86, X86-64, MMX, SSE 4.2
Socket: LGA 1366
Bus: Quick Path Interconnect
Chipset Support: X58



Abbreviated as “WUSB” this short-range, high-bandwidth wireless radio communication combines the speed and ease-of-use of USB 2.0 with the expediency of wireless technology and is based on the WiMedia Alliance’s Ultra-WideBand (UWB) common radio platform, which is capable of sending 480 Mbit/s at distances up to 3 meters and 110 Mbit/s at up to 10 meters. However USB Implementers Forum discourages the practice of calling it WUSB and prefers to call the technology “Certified Wireless USB” to differentiate it from competitors (see below, “Competitors”). Though local regulatory policies may restrict the legal operating range for any given country, Wireless USB was designed to operate in the frequency range of 3.1 to 10.6 GHz.


WUSB are used in devices that are now connected via regular USB cables, such as game controllers, printers, scanners, digital cameras , MP3 players, hard disks and flash drives , and it is also suitable for transferring parallel video streams.

after blue ray whats next?

We all the know about the blu-ray disc that’s out now with its astounding storage capactity(n price :P) But this isn’t all. There are still a few things round the corner that are expected to get bigger than your HDD

The Holographic Versatile Disc (HVD) is an optical disc technology that, in the future, may hold up to 3.9 terabytes (TB) of information, although the current maximum is 250GB. It employs a technique known as collinear holography, whereby two lasers, one red and one green, are collimated in a single beam. The green laser reads data encoded as laser interference fringes from a holographic layer near the top of the disc while the red laser is used as the reference beam and to read servo information from a regular CD-style aluminum layer near the bottom. Servo information is used to monitor the position of the read head over the disc, similar to the head, track, and sector information on a conventional hard disk drive. On a CD or DVD this servo information is interspersed amongst the data.

A dichroic mirror layer between the holographic data and the servo data reflects the green laser while letting the red laser pass through. This prevents interference from refraction of the green laser off the servo data pits and is an advance over past holographic storage media, which either experienced too much interference, or lacked the servo data entirely, making them incompatible with current CD and DVD drive technology.[1] These discs have the capacity to hold up to 3.9 terabytes (TB) of information. The HVD also has a transfer rate of 1 Gbit/s (125 MB/s).


Current optical storage saves one bit per pulse, and the HVD alliance hopes to improve this efficiency with capabilities of around 60,000 bits per pulse in an inverted, truncated cone shape that has a 200 micrometer diameter at the bottom and a 500 micrometer diameter at the top. High densities are possible by moving these closer on the tracks: 100 GB at 18 micrometers separation, 200 GB at 13 micrometers, 500 GB at 8 micrometers and a demonstrated maximum of 3.9 TB for 3 micrometer separation on a 12 cm disc.

The system uses a green laser, with an output power of 1 watt, a high power for a consumer device laser. So a major challenge of the project for widespread consumer markets is to either improve the sensitivity of the polymer used, or develop and commoditize a laser capable of higher power output and suitable for a consumer unit.

Media type Ultra-high density optical disc
Encoding MPEG-2, MPEG-4 AVC (H.264), and VC-1
Capacity theoretically up to 3.9 TB
Developed by HSD Forum
Usage Data storage,
High-definition video,
& the possibility of ultra high definition video

Competing Technologies

In addition to HDV, other proprietary standards are making advances optical disk technology. Other players exist, such as those made by Hitachi Maxell Ltd and InPhase Technologies. Tapestry Media – a holographic format patented by InPhase Technologies – having a storage capacity of 1.6TB and a data transfer rate of 120 MB/s is one such device, while similar a 300 GB disks with a data transfer rate of 20 Mbit/s is in the pipeline for Hitachi Maxell Ltd.

HVD Capacity

* The entire US Library of Congress can be stored on six HVDs, assuming that every book has been scanned in the text format. The Library of Congress is the largest in the world and contains over 130 million items.
* The pictures of every landmass on Earth – like the ones shown in Google Earth – can be stored on two HVDs.
* With MPEG4 ASP encoding, a 3.9 TB HVD can hold anywhere between 4,600-11,900 hours of video, which is enough for non-stop playing for a year.

HVD Adoption

The biggest challenge for HVD will be in establishing itself in the commercial market, which as of now seems to be a distant dream, given its higher cost margins. It is anticipated that a single HVD, when commercially available, may cost anywhere between $100-120 (by 2006 year’s end), and the reader will be priced anywhere in the range of $10,000 to $15,000. However, like anything else associated with technology, the price will soon fall as R&DD costs are recouped and competitions lowers profit margins.

things u can do with ur pendrive

If you’ve got a USB Pen Drive, you can use it for a variety of things, that includes adding portable apps and lots more.But, your Pen Drive can serve some interesting purposes as well – some you wouldn’t have imagined about. Put it to some good use, here’s a quick list of what you can do with it:

1. Install a Linux Distro: guides you through procedures on loading your USB Drive with a Linux Distro. If you’re a geek, you’ll love this setup. If you’re just a normal user, this may come to your use in a variety of situations – you go to a friend’s computer, which is infected with pesky viruses. You need not worry, boot with your Linux-loaded pen drive and do your job, safe and secure.

2) Install MojoPacL:

This is a wonderful app that’ll install itself into a pen drive, and run on top of Windows. You can run your favourite Windows apps, most of them run perfect on this MojoPac layer. The advantage is that none of the modified settings affect the original Windows over which your MojoPac is running on. Quite cool, isn’t it?

3) Automatic Backups:

You’re probably using your USB Pen Drive as a backup device to hold your important documents, but why not make the process easier? Install Allway Sync or Microsoft SyncToy. Both can let you sync files on your computer with your USB Pen Drive with ease. You don’t have to do manual copy & paste files – just insert, click and you’re done.

4)Additional memory:

Vista can use your USB Flash Drive just like your RAM – such a capability is integrated into the OS. Windows XP just can’t use it as additional memory – your flash drive is just a flash drive. Not anymore if you have eBoostr installed. This software program aids XP in using your Flash Drive as a memory device. You might want to give this a try if your computer is hungry on resources and needs some speed boost.

5. Perfect for Gifts:

Indeed, these funky USB Drives are perfect for gifts. There are lots of creative things you could do with it, and then present it to your loved one. If your friend is a businessman/freelancer who has to work with multiple computers, a USB Pen Drive can serve as a perfect gift for the person will have files to carry around. In case your close friend is just a casual user, you could load it with some photos and gift it to that person. Get a pen drive, put your photos in, let them autorun as a surprise when the thumb drive is put in.

6) Exhibit your Skills

Are you a computer/web based worker? Chances are you want to exhibit your skills – what you’ve done in the past. Why not load them on to your USB Drive? For instance, if you’re a graphic designer – you could use it to present your skills, stuff that you’ve worked on in the past and show it off to your clients. Probably, they might hire you right away

7. Enjoy Music, hassle free:

If you’re a serious audiophile, and still got to work in multiple computers, accessing your music collection can be painful. But there’s Winamp to the rescue. You can use Winamp to put your music collection in your USB thumb drive, all still organized and easily accessible. Winamp Portable Edition makes your media library portable, and organized for hassle free listening.
