Hello from the North East

Posted: 08 Nov 2010 12:42 PM PST

I found this site a while ago and have been lurking since then. I had a programming question so I'd thought it was about time I made an account.

Major - Computer Engineering

I am interested in the following (interested in meaning complete beginner and just getting started)

-VHDL
-FPGAs
-Microcontrollers
-RF devices
-Embedded Programming
-C# / GUI programming

Guess thats about it.

See you in the forums.

Basic C++ question about pointers/structures

Posted: 08 Nov 2010 12:38 PM PST

In the book that I am using they use two notations for calling structure data members when using pointers.


(*pt).payRate * (*pt).hours ;
(pt ->payRate * pt ->hours);

I understand that in the first line * is dereferencing the pointer so that I can retrieve the data in the address stored in the pointer variable.

I know the second line gives me the same answer as the first but not sure how. Is the second line a short cut, or is it retrieving data differently than the first line?

Thanks in advance.

Differences between an Analog and Digital Multimeter

Hey Friends,

I have written out a full detailed difference and the better of the two multimeters, i.e. the analog and the digital one.
If anyone of you is wanting to buy a multimeter, please refer to the guide I have written out.

BRAVIA 40" (KLV-40NX500) Full HD TV Reviews & Price In India

Posted: 08 Nov 2010 07:06 AM PST

Sony Television Company has a very popular LCD brand in India called 'Bravia'. Bravia stands for Best Resolution Audio Visual Integrated Architecture. Let's take a look at the 40" BRAVIA, its tech specs and whether the unit is worth the price.

Note: I own this TV :)

Attachment 27

First Impression:

Let's face it: This TV is Gorgeous. Period. No other TV comes closer to to it in terms of looks - and that's when this TV is not ON! Sony is advertising a new design, called 'Monolithic Design' in India. Monolithic design is mostly about fitting a black glass on the entire front panel to cover everything. Thus, when turned off, this TV looks like a plain slab of black glass. Looks totally awesome on light colored walls.

Quick Look at the Special Features:

* Live Color: Powered by an image processor using an algorithm specially developed by Sony, Live Colour™ is able to reproduce incredibly vivid colours on screen

* Full HD (1080p) : You'll need this if you love watching movies on DVD, Blue-Ray Disc Player or own PS3. For normal transmissions, you won't feel much difference.

* BRAVIA Engine 3: In LCD televisions, the main determining factor for picture quality is the processing engine. BRAVIA Engine 3™ is an HD video processor which reproduces pictures with higher contrast, superior colours, and amazing clarity.

* Ambient Sensor: This feature auto-adjusts screen's brightness and contrast according to your room's lighting conditions.

* Intelligent Picture Plus: This function removes the noise from analogue input (RF) and 'cleans up' the picture.

* MPEG Noise Reduction (NR): Gets rid of both speck-like noise around subtitles and block noise that are usually found in fast-moving scenes. Effective for SD, HD, and even unconverted images, MPEG NR ensures a sharper and more beautiful result each and every time.

BRAVIA Sync: This function lets you link all your BRAVIA Sync enabled devices together.

-----
Firmware Upgrade: You can upgrade the software that runs this device. I'm yet to perform an upgrade, so no comments at the moment.

My opinion: This TV is AWESOME. The picture quality is above expectations and explodes if you're watching a BluRay movie! You can also use this TV as your big digital frame by connecting a USB loaded with photos/wallpapers etc. The TV has 4 HDMI inputs to let you connect your PS3, DVD player, camera and other devices. The TV is totally worth the price. This model is available in India for a price of Rs. 63,990/-

Project Idea For Final Year CS Engineering: Hindu Temple Management System

Posted: 08 Nov 2010 06:25 AM PST

So, have you thought of this?

Hindu Temples have too many systems working in perfect harmony - and a software to manage it could very well be your final or third year project!

So here's an idea that struck my mind after visiting a temple in the morning today. Overall, there are following systems working in any typical Hindu Temple -

1. Security ( Guards at the door )
2. Footwear (visitors are asked to leave their shoes outside the entrance)
3. Donations ( visitors who donate to the development & maintenance of the temple)
4. Employees ( cleaners, pujari, volunteers and so on..)
5. Prasad distribution

..and so on..

I think your final year project could very well be based on computerizing everything. Of course, you can use your own creative juices to develop this idea further.

What say?

Heavy weight and light weight process

Posted: 07 Nov 2010 10:39 PM PST

Please tell me the difference between heavy weight process and light weight process. All i know is that a heavy weight process has its own address space and light weight processes share the same address space. Is there any other difference?

Gone are the days when searching on the web meant simply navigating through the pages! Browser is now a window to keep connected to everything. This concept leads us to think about why not have a personalized browser? – A browser that fits our needs.
