Understanding Resolution

A resolution of 800 x 600 means that the entire monitor shows a grid that’s 800 pixels wide and 600 pixels high. A pixel is the smallest unit of measurement on a computer monitor, and is otherwise known as "dot". A resolution of 800×600 gives 480,000 pixels. Whil 640 x 480 resolution gives 307,200.

A screen resolution isn’t tied to the size of monitor. A 17" monitor can have a higher resolution than a 19" monitor. However it makes sense for a larger monitors to use higher resolutions. That’s because on a small monitor, high resolution looks cramped. Monitors support awide range of resolutions, and you can choose the best compromise between showing lots of content (a higher resolution) and making sure that content isn’t too small (a lower resolution).

How Google’s Page Rank Works?

Google uses a rating system called PageRank to size up different web pages and determine how they rank.

Page Rank isn’t usedto find search results; instead it uses to order them. When you perform a search with Google, it pulls out all the sites that match your search keywords. Then it orders its results according to the PageRank of each page.

The basic idea behind the PageRank system is that the value of your Web site is determined by the community of other Web sites that link to it. There are few golden rules:

1. The more sites that you link, the better.

2. A link from a popular site (a site with a higher PageRank) is more valuable that a link from a less popular site.

3. The more links a site has, the less each links is worth. In other words, if someone links to your site and just a handful of other sites, that links is valuable. If someone links to your site and hundreds of other sites, the link’s value is diluted.

Although Google regularly fine tunes its secret PageRank receipe, Web gurus spend hours trying to deconstruct it. 

How Google Adsense Creates Targeted Ads

Everytime you serve up a Web page that contains Google ads, the Adsense script sends a message to the Google Web server asking for ads. This message includes your ad preference information and your unique client ID (something like pub-158753245895453; you can set it in the script code).

The first time Google receives this request, it realizes that it hasn’t examined your page yet, and it doesn’t know what types of ads are best suited for it. Instead, Google sends you a block of generic ads ( or sends back your alternate content, if you choose that feature). Google also adds your page to a list of pages it needs to visit. Sometime in the next couple of days, the Adsense robot heads over to your site and analyzes its content. From that point forwards, you’ll see ads that are based on the content of your page.

If 48 hours has pass and you still aren’t getting targeted ads, there could be a problem. One of the most mistakes is putting ads on pages that don’t have much text, in which case Google can’t figure out what your site is all about. (Remember, Google only considers a single page-the one with the ad unit-not any other pages in your site.) Another potential problem occurs if you put your ad in an inaccessible page. For example, Google bot can’t get to any page that’s not on the Internet - pages on your personal computer or local network. Also with pages that are password-protected. Some Web sites block off robots using exclusive rules. These also stop the Adsense bot cold.

How to Make your Text Readable

Text on the Web isn’t like text in print. Browser has limited patience. Here are some rules to make sure your making good use of text in your Web pages:

1. Split text into small sections. Web pages and the viewers are responsible for clicking. They don’t want too long paragraphs.

2. Create short pages. If a page is longer than two screenfuls, split it in two pages. It gives you easier to read and adds more web pages.

3. Divide content into several pages. the next step is to link these pages together. It gives readers choices what they want to read.

4. Put your most important information in the first screenful. This technique is called designing above the fold. It makes sure that there’s something eye-catching or interesting that the reader can look without scrolling.

5. Don’t over use formatting until you understand style sheets. If you do, you’ll leave a big mess that you only need to clean up later on.

Spyware

A spyware program is an unwanted plug-in that attaches itself to your browser or operating system without your permission. It then harasses you with advertisements, or record your surfing habits and send them to a Big-brother-like marketing company. Spyware thrives like a weed, particularly on the Windows operating system. It is notoriously difficult to remove, even you weren’t using your browser, you should have your computer checked out. The best remedy is a spyware removal tool that scans delinquent programs and removes them, much like a virus scanner.

Can I Run a Web Server?

In theory, you can. But in practice, it’s not easy. (1) The first you should consider is that you need to have a reliable computer that runs 24 hours a day. That computer also needs to run special web hosting software that’s able to serve up Web pages when browsers request them.

(2) Second, your computer needs a ‘fixed IP address’. The IP address is a numeric address that identifies your computer on the Web.

Most ISPs (Internet Sevice Providers) assign new IP addresses, which means most people can’t use their computers to host a permanent Web site.

You can contact your ISP provider to ask them for a fixed IP address service. The typical cost is usually higher than ordinary web access.

The Difference Between <b> and <B> tag

Most Common People asks: "Should I use uppercase or lowercase tags?"

HTML isn’t case sensitive. But most Web designers use only lowercase for these reasons:

1) Newer Web standards like XHTML aren’t as lenient. They’ll force you to use lower tags.
2.) Web authoring tools like Frontpage and Dreamweaver always use lowercase tags.

Other Web fans still use uppercase tags because it stands out in the sea of HTML. But for playing safe, lowercase tags is most suitable.

Google Earth

Recently been addicted with this Google Earth map. It allows to navigate and map the world using google’s software Google earth. It was like actual flying from country to country. it allows too to navigate even the sky and stars. A very useful for architects, engineers and every one else who are interested in mapping. Got excited seeing the top of my roof and my neighbor’s roof. Allows me to analyze how long should I travel from here to there.
