With the Advancements in technology, new dimensions to internet and high fidelity to Internet applications, developers launched a standard platform to make internet applications more sophisticated and called them Rich Internet Applications (RIA). Some of the most happening and important RIAs are :

280 Slide www.280slides.com

Aviary www.aviary.com/tools

Crazy Egg www.crazyegg.com

Google Maps www.maps.google.com

Net Vibes www.netvibes.com

and the list goes on …

One of the most happening RIA for online Webinars these days is

DimDim

So, the next questions comes to ones mind is ?

What is Dim Dim, what’s this Geeky name all about ?

Let’s have a detailed analysis and walkthrough DimDim

DimDim

Dimdim is a software company that provides a web-based platform for real-time, rich-media collaboration and meetings. Dimdim provides free web conferencing service where users can share desktops, show slides, collaborate, chat, talk and broadcast via webcam.

It’s got some great features including

• desktop sharing
• application sharing, with specific shortcuts for Word, Excel, PDF, Browser, Powerpoint
• whiteboard
• ability to upload and show presentations
• embedded live video and audio so you can talk to others in the meeting
• public and private chat (although I confess I don’t know how the presenter can have a private chat when their screen is in full view of everyone in the meeting)

and its all free for 30 days evaluation, after that you can always set-up a new account or buy a reasonable package according to needs. For a home user, the free accounts are just more than sufficient.

So, how will it help you ?

consider you want all your family members to chat or more precisely in a video conference then DimDim does the magic for you. ( You can also chat private & public at the same time). You can host meetings that are set private and only allow the desired members to join

You Can post widgets about invitations to a certain meeting on your personal homepages, blogs or even on facebook. So, all your friends or family members have to do is to signup and they can be a part of the meeting on the specific date and time

Ever wanted someone to help you with the computer stuff ? Well desktop sharing and application sharing makes it easy for your friends or family members in your network to assist you .

You can also work with your colleagues by uploading or viewing presentations .

The best Part ? you don’t really have to install a single thing or to do any geek stuff for all this. All you have to do is either to Host or Join a Meeting and can send/receive invitations via emails . Simple as that.

Still not satisfied ? give it a try www.dimdim.com and you will definitely feel its power and will be moved.

1. The ones we had ages ago and we operated using a Stylus
2. The one we use now with our fingers like Apple’s Iphone

Technically speaking these two classes are named as :

The former being resistive touch screens and the latter as Capactive Touch Screen

A very general question that comes to ones mind is, which one is better ?

Well, the answer needs to be broken down for understanding. If one had to give one line statement that would be

Definitely Capactive Touch Screen

Everything comes up with the goods and the bads , so, one just cannot superimpose ones own experience or belief. To qualify and side up with the statement one should understand that the technological improvements gave birth to Resistive Touch Screens and they grew bigger and better and Became The Capactitive Touch Screens; just like you see a child growing , adapting, gaining, learning and experiment when he grows older.

Both of the technological comes with goods and the bads, e.g. resistive screens are more precise than the capactive screens, while capacitives are more sensitive and faster in operation. To get an insight story, lets figure out the technology behind these two screens ( keeping in mind the comparison is made between standard resistive touch screens and advanced multi-touch capacitive screens for mobile devices )

Resistive Touch Screen

Resistive touchscreen displays are composed of multiple layers that are separated by thin spaces. Pressure applied to the surface of the display by a finger or stylus causes the layers to touch, which completes electrical circuits and tells the device where the user is touching. As such, resistive type touchscreens require much more pressure to activate than capacitive touchscreens.

Capacitive Touch Screen

In the capacitive system, a layer that stores electrical charge is placed on the glass panel of the monitor. When a user touches the monitor with his or her finger, some of the charge is transferred to the user, so the charge on the capacitive layer decreases. This decrease is measured in circuits located at each corner of the monitor. The computer calculates, from the relative differences in charge at each corner, exactly where the touch event took place and then relays that information to the touch-screen driver software. One advantage that the capacitive system has over the resistive system is that it transmits almost 90 percent of the light from the monitor, whereas the resistive system only transmits about 75 percent. This gives the capacitive system a much clearer picture than the resistive system.

which one is better ?

The Answer would be Capacitive Touch Screen Devices but they come with an added penalty of being more costly than the resistive touch screen devices and in some cases almost double the prices.

which capacitive touch screen phone is better ?

Until October 2009, Iphone won the unprecedented technology war, but, a major competitor shook its bases to the grounds and that is :

HTC HD2 which runs on Windows Mobile 6.5 operating system. Technically speaking the feel of touch screen for HTC HD2 still lacks details when compared with iphone. i would say, standing at Top holding iphone in your hand, you will find HTC HD2 on 9th floor but, if you can scroll down a bit and see both these devices head-to-head you will definitely change your mind.

No doubt, HTC HD2 looks macho and ready to rock , but if you are still not convinced you should try the powers of HTC HD2 and the very very strong operating system running it. This Device is truly a HD device with a screen size of roughly a netbook and delivers great quality results. Backed by Windows mobile platform it comes up with some great features like Wireless Router . If you still beleive Iphone wins the battle by its sleek looks, ultimate touch screen sensation, the best music on the go ; then you should consider that a mighty competitor has hit the grounds and the next release might wipe off Iphone .

watch this youtube video for head-to-head comparison and find out how much HTC has improved in this particular model comparing it to HTC Hero and HTC Tattoo

Happy Birthday, Zeitgeist!
 

KFC launches a sandwich that uses fried chicken filets instead of buns. Seriously.

There were 23 factors tested and some of the factors that interested me were:

• Install OS
• Move 100MB files
• Move 2.5GB files
• Network transfer 100MB files
• Network transfer 2.5GB files

The systems considered for benchmarking were:

• An AMD Phenom 9700 2.4GHz system fitted with an ATI Radeon 3850 and 4GB of RAM
• An Intel Pentium Dual Core E2200 2.2GHz fitted with an NVIDIA GeForce 8400 GS and 1GB of RAM

The overall results were very promising for Windows 7. It outperformed its predecessors Vista and XP in almost every factor tested and ranked #1. Windows Vista ranked #2 with the AMD and #3 with the Intel. Windows XP ranked #3 with the AMD and #2 with the Intel. But the scores weren’t big enough to compare between Windows Vista and Windows XP.

Below is the score for some of the factors listed above:

And the overall results:

Sure these tests show a huge improvement on Windows 7 even at this early stage when compared to Windows Vista(during its beta stages).
