A Spyware Guide: Detect and Prevent Infection

The Anti-Spyware Coalition (ASC), which is a group of academics, anti-spyware companies, and consumer organizations, defines spyware as:

"Spyware is a term for Tracking Software deployed without adequate notice, consent, or control for the user."

Spyware programs are installed into your system without your knowledge, in order to show you unwanted advertisements. They can record your personal data and browsing trends for showing better targeted ads. Unlike viruses or Trojans, spyware may not damage your software or operating system. They can, however, slow down your system a lot.

How Do Spyware Infect A System?

Facetime Communications, an online security company, estimates that almost 80 per cent of the world's computers are affected by spyware. Spyware installation can happen through various means. Most of them rely on the security loopholes in the host system. Here are some of the tactics by which they infect a system:

1. Automatically: Some spyware, such as Claria Corpor…

Creating Presentations Online

You may have noticed that in some of the previous posts, I have included online presentations, most of which are viewable directly from the browser, without having to download and view privately. Though you can create presentations using MS Office PowerPoint, Apple Keynote, or Open Office Impress and upload the files for online viewing, it seems easier to create the presentation itself online. In this article, let's see how you can do that.

1. Google Docs

Go to and sign in using your Google account. Google Docs provides a complete feature-rich presentation tool. Adding slides, describing them, adding pictures, animations, and videos with Google presentation tool are pretty easy. If you wish to use your offline presentation, you can upload it. The formats that can be uploaded include Microsoft and Open Office versions.

The completed presentations can be viewed online with a Google account. They can be embedded to any website.

Usage of Need and Dare

Both need and dare can be used as auxiliary verb and main verb. When used as auxiliary verb, it works just like other modal auxiliaries, such as 'can', 'may', 'will', 'shall', etc. When used as main verb, they are like any other verb, such as 'run', 'go', 'come', 'take', 'work', 'joke', etc. Examples:

As auxiliary verb:
They needn't walk home, they can catch a bus.
How dare you disobey my orders?
Need you really take that risk?
She dare not make the first move at any cost.
I need drive to Joe's immediately.
As you have seen, dare and need don't agree with the subject or use 'to' when used as modal auxiliary. It's just like 'can' or 'may': such as, "I may drive to Joe's immediately", "Can you really take that risk?"

Used as normal verb:
I need to get the attestation before applying.
She does dare to do a lot of things.
Do you dare to compete with…

The Adventure of Charles Augustus Milverton, by Sir Arthur Conan Doyle

Here is a short story in the Sherlock Holmes Series, by Sir Arthur Conan Doyle. This is one of those stories which I read first among this series and hold a good deal of nostalgia to.

The Adventure of Charles Augustus Milverton
by Sir Arthur Conan Doyle

It is years since the incidents of which I speak took place, and yet it is with diffidence that I allude to them. For a long time, even with the utmost discretion and reticence, it would have been impossible to make the facts public, but now the principal person concerned is beyond the reach of human law, and with due suppression the story may be told in such fashion as to injure no one. It records an absolutely unique experience in the career both of Mr. Sherlock Holmes and of myself. The reader will excuse me if I conceal the date or any other fact by which he might trace the actual occurrence.

We had been out for one of our evening rambles, Holmes and I, and had returned about six o'clock on a cold, frosty winter's evening. A…

There is No More GeoCities

GeoCities, Yahoo's popular free website creation service is coming to an end this year. The free hosting service, which was a hit for Yahoo since the beginning of this generation of the Web was not successful in terms of making money for the Web giant.

Yahoo had bought GeoCities in 1999 spending about 3.6 billion dollars. The following is what you will find at the GeoCities home page now.

Though the existing accounts will remain live, there is no guarantee that they will remain so in the future. As a measure to monetize GeoCities userbase, Yahoo recommends upgrade to the Yahoo Web Hosting Service as well.
