"Take Yahoo Inc.'s 2-petabyte, specially built data warehouse, which it uses to analyze the behavior of its half-billion Web visitors per month. The Sunnyvale, Calif.-based company makes a strong claim that it is not only the world's single-largest database, but also the busiest.
Based on a heavily modified PostgreSQL engine, the year-old database processes 24 billion events a day, according to Waqar Hasan, vice president of engineering in Yahoo's data group.
And the data, all of it constantly accessed and all of it stored in a structured, ready-to-crunch form, is expected to grow into the multiple tens of petabytes by next year."

"Instructor: What do you think the author’s meaning was behind this book?
Student: I personally find it similar to the genocide in Darfur.
Instructor: But we’re reading Pride and Prejudice.
Student: Just as the weeping mothers in Darfur find no solace, neither will Lizzy in her search for the true love to complete her being.
Instructor: Lizzy and Darcy just got married.
Student: Are you condoning genocide? The wailing little children will never forget the hypocrisy of America! Diversity! Fair trade! Hurricane Katrina!

"It's called the 'Miracle Fruit' because it can alter the taste of sour items. Miracle Fruit is also easier to say, and spell, than it's official name - synsepalum dulcificum.
Although the plant produces fruit throughout the year, there are occasions when shipping might take more than a week, so only place an order with the understanding that the Miracle Fruit will be shipped upon availability."
During the 1970s, a ruling by the Food and Drug Administration dashed hopes that an extract of miraculin could be sold as a sugar substitute. In the absence of any plausible commercial application, the miracle fruit has acquired a bit of a cult following."
For most of my life, I looked for Thomas R. St. George, not knowing if he had survived the war, or where he might be if he did. Through the wonders of the Internet, I found him in 2007. To my amazement and delight, I found that he had published several more books, all of which I now own and treasure."

Ailerons really bring an airplane to life because they allow the airplane to roll. Most everyone that is serious about this hobby flies planes with ailerons. For this reason I want to focus our discussion of RC airplane controls on four channel radios.
A radio with four or more channels will have elevator/aileron control on the right stick and throttle/rudder control on the left stick. The ailerons are the primary turning control for an airplane with ailerons."
Innovation, convenience and ease of flight – an ultra-micro flyer for everyone. Small enough, and slow enough to be flown in a basement, garage, living room, or other indoor spaces."

Every time a spec was needed, invariably, a debate over the format of the spec would arise - with developers preferring a plain text document on a wiki, and business people preferring traditional tools such as Microsoft Word based on a set template.
Cue reStructuredText - an easy-to-read, plain text document format designed to keep content and the style/formatting of content separate. Author the content once, then present it in a variety of formats - like html and pdf - with infinite possibilities for styles and templates.
After numerous proprietary-format-written specs that he couldn't open, Andy decided to build rst2a as an advocacy site to accomplish a few goals:
* Encourage the creation of additional rst styles.
* Present these styles in a digestable way, for people to download and use.
* Make it easy to convert rst documents to multiple formats, without having to install a heap of software locally.
* Help establish rst as a viable format for non-technical users."

This guide is meant to get you started using Mechanize. By the end of this guide, you should be able to fetch pages, click links, fill out and submit forms, scrape data, and many other hopefully useful things. This guide really just scratches the surface of what is available, but should be enough information to get you really going!"
mechanoid is a programmatic browser written in Python. It is intended as an engine which will do things like log in as SourceForge project admin and do a Quick Release or send and receive Yahoo mail. mechanoid is a fork of John J. Lee's mechanize."

Normally, caveats like that might send you away from an open-source project. Despite the issues, Twisted is worth it because the code is very good, and it solves your problem. The project is very actively maintained, but it's by people who are good at writing (and testing) code, and not so good at documentation. It's definitely worth using, but you should be ready to roll up your sleeves. However, if you can fit your project within what I'm showing in this article, things should go easily."

"The tool I ultimately chose for the purpose of the detection itself is a little free app appropriately called Proximity. This is a thin little program that does one thing, but does it well -- that is to sit in the background and scan for a given Bluetooth device at regular intervals. When it detects a change in the device’s availability, it simply calls one of two Applescripts: One for the device leaving range, and another for when the device enters range.
So, armed with that I set out to create two Applescripts that would perform the following tasks:
When the Bluetooth Device enters range:
•Deactivate the Screen Saver Password.
•Deactivate the Screen Saver.
•Reconnect the phone to the OS X Address Book
•Sync the phone using iSync
When the Bluetooth Device leaves range:
•Activate the Screen Saver Password.
•Activate the Screen Saver."

"Uprooted, we'll follow you alone.
Today once again we'll carry, fight, multiply and be eaten.
Dug up, we'll meet again and be thrown around.
But we'll follow you forever.
I guess it's time to play.
Maybe we'll go out quietly.
Ah... ah... falling in love...
Under that sky...
On this planet, where so mnay lifeforms live,
Today once again we'll carry, fight, multiply and then be eaten.
Uprooted, we'll gather, and be thrown.
But we won't ask you to love us.
I guess it's time to play.
Maybe we'll try harder.
Ah, ah... falling in love...
Under that sky...
We'll work together, fight, and be eaten,
But we'll follow you forever.
We'll fight, be silent, and follow you,
But we won't ask you to love us."
