Adblock Plus - Another Firefox bonus!

Adblock Plus LogoI have mentioned before just how much I like Firefox. While some techies shun it for its slightly slower speed (compared to other browsers such as Chrome or Safari), developers have long loved it for its remarkably handy plugins. I am not quite sure how I would get along without Web Developer.

Today, I just installed Adblock Plus in an effort to get rid of contextual ads – which I loathe. It worked perfectly!

For those of you who are new to the term “contextual ads”, these are advertising links found in the text of some pages. Often, they have a double underline. They usually open a pop-up when you hover over the link. Kontera and Intellitxt are two versions of contextual advertising.

The problem with many unscrupulous ads is that they distract from the content. This is especially true with contextual advertising. The text in the pop-ups they generate have absolutely nothing to do with the page content. Links inside Web content is already distracting enough. Contextual advertising ironically has nothing to do with the context of the page.

The Adblock Plus add-on nixed this, and all of the rest of the advertising on the page, beautifully. I was left with exactly what I wanted to see.

Here is an example of a page before and after I used Adblock Plus.

If you are not using Firefox and its plethora of add-ons, I recommend giving it and them a shot. It can make your Web browsing so much more pleasant.

Welcome to the Petabyte world

Welcome to the Petabyte world

Petabytes in IncrementsThere was a time that I actually heard the following.

“Wow, 128 kilobytes? You’ll never use that up!”

I think that was back in the early 80’s. I have wallets that have more hard drive space than that now.

As computers increase in speed, programs require more hard drive space and more computer memory. Moreover, Moore’s Law dictates that the computer processing speeds will double every two years.

So, welcome to the Petabyte Age. While most computer users understand the term “Gigabyte”, and many are familiar with “Terabyte”, Petabyte is just coming into its own.

How much is a Petabyte? Here is some perspective:

1 Byte (8 bits) = 1 word in English

1 Kilobyte (1,024 Bytes) = 1 very short joke

1 Megabyte (1,024 Kilobytes) = 1 small novel (25,000 pages or so)

1 Gigabyte (1,024 Megabytes) = 10 yards of books on a shelf

1 Terabyte (1,024 Gigabytes) = 50,000 trees worth of printed paper
(10 terabytes = the printed collection of the Library of Congress)

1 Petabyte (1,024 Terabytes) = 10 million filing cabinets filled with text

Visit Mozy’s blog on How Much Is a Petabyte for a great set of graphics to put the Petabyte into perspective.

What is bigger than a Petabyte?

1 Exabyte = 1,024 Petabytes
5 Exabytes = All words every spoken by human beings

1 Zettabyte = 1,024 Exabytes
In 2008, America consumed 3.6 Zettabytes of information (mostly my daughter on Facebook)

1 Yottabyte = 1,024 Zettabytes (that’s 1,073,741,824 Petabytes)
1 Yottabyte = one Byte for every star in the universe
7,000 Yottabytes = one Byte for every atom in the human body

Okay, now my brain hurts…
