How Google Works

Fact and not



The magic that makes Google tick

  • Over four billion Web pages, each an average of 10KB, all fully indexed
  • Up to 2,000 PCs in a cluster
  • Over 30 clusters
  • 104 interface languages including Klingon and Tagalog
  • One petabyte of data in a cluster - so much that hard disk error rates of 10-15 begin to be a real issue
  • Sustained transfer rates of 2Gbps in a cluster
  • An expectation that two machines will fail every day in each of the larger clusters
  • No complete system failure since February 2000

Repair Internet/Network connection

Before the service call


Loss of connectivity is usually solved by the big three:

  • Restarting the computer
  • Unplugging the router
  • Unplugging the modem


Vista has a built in feature that you'll usually find on the Task bar.
It indicates current connections, but if you right click you can find Diagnose and repair.

DNS FAQ

Domain Name System


Here's a concise collection of answers about the inner workings of the internet.

For instance:

What is DNS (Domain Name System)?


Websites have both a "friendly" address, called a Uniform Resource Locator (URL) and an IP address. People use URLs to find websites, but computers use IP addresses to find websites. DNS translates URLs into IP addresses (and vice versa). For example, if you type http://www.microsoft.com into the address bar in your web browser, your computer sends a request to a DNS server. The DNS server translates the URL into an IP address so that your computer can find the Microsoft web server.

Site Maps

Point the way



"As a Web designer and HTML builder, one of the first places I visit on a Web site is the site map. The site map shows an entire overview of the structure of the site, and more importantly, indicates how much effort was put into usability testing during the site's construction.




Learn how to chart a better site map
By Jim Kukral -Builder.com


According to Jakob Nielsen's Alertbox Usability Study on Site Maps

"27 percent of users turn to site maps when asked to learn about a site's structure. If your site map is poorly designed, you may lose 27 percent of your Web visitors. That could translate into millions of dollars of missed sales for an e-commerce site, or a massive amount of missed leads for a service company."


(A Site Map is a guide to a web site used by visitors. A Sitemap is a file used by search engines to index entries on a site. )

Privacy is Gone

Hide that search


We're not alone in the great world-wide internet.

"In 2006, AOL unwittingly divulged the personal lives of 650,000 customers by publishing their search histories as research data. Despite AOL's attempts to anonymize the info, the New York Times quickly outed a 62-year-old lady in Georgia whose searches revealed her dog was wetting the upholstery."

Internet Connectivity

Free tool from MS


"The Internet Connectivity Evaluation Tool checks your Internet router to see if it supports certain technologies. You can use this tool on a PC running either the Windows Vista or Windows XP operating system.

If you're planning to run Windows Vista, this tool can verify whether your existing Internet router supports advanced features, such as improved download speeds and face-to-face collaboration using Windows Meeting Space.

The tool is intended to be run from a home network behind a home Internet (NAT) router. Running this tool from behind a corporate firewall or on operating systems other than those specified above won't produce accurate results. This tool requires administrator privileges to run.

Gmail Features

The top 10


Bill Kee, Associate Product Marketing Manager for Gmail, has a blog and has listed 10 major features of the free web based email system.
Including:

"When you get an email that references an address, look to the right and you'll probably see a link from Gmail pointing you to a map of the address on Google Maps.

Gmail also recognizes email text that refers to an event (e.g., 'dinner tomorrow at 8pm'), and will give you a link to add it to your calendar.

It'll even pick up on package tracking numbers from UPS and link you directly to the tracking page, so you don't have to copy and paste the number. I really like this last one when I order stuff online and want the instant gratification of knowing a package is on its way.

MHTML

One file web pages



When a web page is created using HTML, the coding is normally contained in one file and the graphics in separate folders.

The Mime HTML or MHT/MHTML format changed that.

Starting with Office 2000 as an add-in and carried through XP as a "Web Archive" option, the format emerged in Office 2003 as a "Single file web page" selection in the File Save As dialog box.


Features in Internet Explorer 5 +


Here are the Save As choices available in an application such as Word:



  • Web Page, Complete means that the contents of the page (including any pictures) will be saved into a folder as separate files, similar to those on the server hosting the site.

  • Web Page, HTML only means that only the HTML information will be saved. This option and Web Page, Complete will enable you to open the file for viewing in Internet Explorer (or any other browser) at a later time, even when you are offline.

  • Web Archive means that the page will be saved, along with any images it contains, as a single file. You can view a Web Archive later without being connected to the Internet.

  • Text File means that only the text on the page will be saved, not the HTML (or any other) formatting, including graphics.

Guide to CSS

Map through the forest


Dustin Diaz:
"Ok. Let's set the record straight. There is no official guide for each and every CSS shorthand property value. So let's work together and put one together shall we?

Ok. Straight to the business. Anytime I've ran into a specification (besides the confusing mess at the W3C), it turns into showing off a couple of examples and you're supposed to be set on your way.

Well well. Over the years, I've found quite some interesting unknown quirky facts about these shorthands. . . hence this Guide was born."

Define URL Pieces

More than dot com


Google engineer and blogger Matt Cutts has defined the pieces that make up a Uniform Resource Locator.

At least as Google refers to them when they're sitting around in their backrooms
Domain

Dynamic URL


Fragment or a Named anchor


The Googlers I've talked to are split right down the middle on which way to refer it. Disputes on what to call it can be settled with arm wrestling, dance-offs, or drinking contests. Typically the fragment is used to refer to an internal section within a web document. In this case, the named anchor means "skip to 2 minutes and 30 seconds into the video."


Host


Parameters


Path


Port


Protocol


Second-level domain


Static url


Subdomain


Top-level domain

Surrogate Image Server

Temporary


"When posting on message boards or blogs, often you want to show or link to an image on another website. Directly showing or linking to that image is called hot-linking. It's generally bad because it leeches bandwidth from the host site, and as a result many webmasters have their servers set up to prohibit hot-linking.


ImgRed.com lets you simply enter the original URL in your post as you normally would, but with http://imgred.com/ written before the URL. When this is viewed, the image will be copied once* to imgred.com, and from then on the image will always be served from imgred.com instead of the host site.



*ImgRed is not an archive service, and occasionally its cache is cleared out (once a month or so), so images are not literally cached forever.

Viddler Video Streamer

Player and free video storage





"You can upload many videos at once, and in various formats, too.(mov .avi .wmv .mpeg).

You also won't have to worry about file size - just keep any video you upload under 500 Mb.

Timed Tags
Moments on the timeline of your video are taggable, so you can classify and share instances in time. Timed tags are searchable, too - a great way to explore the content on viddler.com

Timed Comments
Your position in the timeline of a video determines where your comment will be posted to, which brings the discussion to a whole new level!

Use Your Webcam
Got a web camera? You can use Viddler to record footage directly from the camera to the website. There's no third-party software


"Viddler is very different from other video-delivery based websites, because we stream our videos instead of having the user download it.

That means you get to watch videos without having to wait for the entire video to load.

This is especially useful when you want to view the last few minutes of a very long video.

It's a secure system and prevents other people from watching the video (in ways they're not supposed to) or ripping the video off the site.

Video that you host with Viddler cannot be stolen, or used in any fashion, unless you set your sharing options to allow it."

Wayback Machine

Archived sites



Ever want to see what a web site looked like in the past?

Take a look at the the Wayback Machine .

"Browse through 30 billion web pages archived from 1996 to a few months ago. To start surfing the Wayback, type in the web address of a site or page where you would like to start, and press enter. Then select from the archived dates available."


The Internet Archive
"is building a digital library of Internet sites and other cultural artifacts in digital form. Like a paper library, we provide free access to researchers, historians, scholars, and the general public."


Ghostsites

"This feature of Ghost Sites was launched in early 2000; it is an image gallery of some 1,250 screens captured from some 900 Web projects that for various reasons "went dark" during the years 1998 to 2004. Some had a chance to post a self-penned epitaph in the form of a "farewell screen"; others simply expired and drifted lifelessly, with no visible indications for their demise."

Nameless Surfing

Masked strangers


Anonymous surfing is exactly what the terms suggests. You go online without revealing any of the personal or technical information on your computer. It's done by having a special computer -- called a proxy server -- screening you from the websites you are contacting. Your computer contacts only the proxy server, which contacts the website for you. The website, in turn, sees only your proxy server and not you. In addition to hiding your IP.

From Ask Bob Rankin:

Internet History

Two tin cans



From the FCC:

The Internet: A Short History of Getting Connected.
When the Defense Department issued a $19,800 contract on December 6, 1967, for the purpose of studying the "design and specification of a computer network," the world didn't take notice. But it should have. For, from that small, four-month study grew the ARPANET. And, from ARPANET emerged the Internet.
