Overheard: Why page views are important for lead generation

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
A better gauge of a Web entity’s user profile would be to look at the composition of PVs, because heavy users will drive PVs and tend to counteract the diluting impact on the core target that a UV metric can have. In December 2007, for example, Media Metrix reported that 62% of Unique Visitors to aarp.org were age 50+ (eligibility for AARP kicking in at age 50); but 77% of their Page Views were accounted for by persons 50+, and 79% of their total minutes.

But there is another important reason to think in terms of pages when assessing a web entity’s audience make-up. Ads are distributed across pages, not UVs. The more pages one consumes, the more ads one is exposed to, and the more likely that consumer is to see your ad. If an advertiser runs a campaign on a site, the audience profile of the exposures to that campaign will tend to mirror the profile of the Page Views, not the Unique Visitors. In the AARP example above, then, let’s restate thusly: 62% of the aarp.com unique audience is comprised of persons 50+, but these persons see almost 80% of the ads.

Josh Chasin, Where The Buys Are: Ads Live On Pages

Something else I want to remember that Tris Hussey wrote: Don’t look at a link away from your blog/web site as asking people to leave, think of it as building a larger network of people who will link to you.

Overheard:Blade servers good for disaster recovery plans

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
anne_skamarock.gif Since blade servers are densely packed, the companies offering blade chassis solutions have put a great deal of time and effort into creating highly efficient power distribution systems and cooling capabilities within the chassis. On average, a blade chassis uses 30% less power than the same number of 1U or 2U servers. Each watt saved in power equals a watt of cooling saved.

Overheard: Drupal is like a giant bin of free Lego blocks for building a Web site

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
jeff_robbins.jpg If you are unfamiliar with Drupal, just imagine it as a giant bin of free Lego-style building blocks for creating any type of web site. Its modular system and underlying application framework can allow rapid deployment of incredibly feature-rich sites. All you need to do is imagine what you want to build and start putting together the pieces.

Overheard: Drupal runs on any OS that supports PHP

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
drupal.gif The operating system is at such a low level in the stack that Drupal does not care much about it. Drupal runs successfully on any operating system that supports PHP.

John VanDyk and Matt Westgate, What Is Drupal?

Drupal can be used to build an Internet portal; a personal, departmental, or corporate web site; an e-commerce site; a resource directory; an online newspaper; an image gallery; and an intranet, to mention only a few. It can even be used to teach a distance-learning course.

Drupal originated as a bulletin board system developed by Dries Buytaert in the Netherlands, and became an Open Source project in 2001. When establishing his original Drop.org Website, Buytaert wanted to call the site “dorp” (“village” in Dutch), but made a typo when checking the domain name, and decided the altered form sounded better (Drupal is a transliteration of the Dutch “druppel” which means droplet).

Overheard: SPICE is multi-million dollar industry

Margaret Rouse Margaret Rouse Profile: Margaret Rouse
spice1.gif Let me begin this talk with an explanation for those in the audience that think that SPICE is a cable TV channel that offers shows of women in various states of undress. The SPICE I am talking about is about twenty years older and certainly nowhere near as exciting.

Larry Nagel, The Life of Spice

Larry Nagel created SPICE.

When people ask me why SPICE became so widely used, or what did I do to make SPICE
so widely used, the honest answer is “I don’t know.” But I can speculate. The biggest
reason, directly attributable to Don Pederson, is that SPICE was developed at a public
university and was public domain from the beginning. Because it was developed primarily
as a teaching tool to provide students insight into integrated circuit performance,
SPICE was rapidly embraced by many engineering colleges throughout the world. When
students entered the integrated circuit industry they would write to Berkeley to obtain a
copy of SPICE to use on their job. And so the copies of SPICE proliferated and the usage
of SPICE grew. It’s a several hundred million dollar industry now, depending on how you count it.

Overheard: How atomic clocks work

first_atomic_clock.jpg Without atomic clocks, GPS navigation would be impossible, the Internet would not synchronize, and the position of the planets would not be known with enough accuracy for space probes and landers to be launched and monitored.

Douglas Dwyer, How Atomic Clocks Work

The big difference between a standard clock in your home and an atomic clock is that the oscillation in an atomic clock is between the nucleus of an atom and the surrounding electrons.
