Emerging Technology in Web Development

This is a paper that I wrote for an Information Systems class in 2002. It gives a basic overview of web applications – the language and how data is transmitted across the Internet from the user to the server (the web site the user is trying to view) and back to the user. It uses ColdFusion as an example. Also talks about Flash, a multimedia technology. This essay was written in 2002, so it is a bit outdated, however, the principles of web technologies are still the same.

Google Sitemaps

Background

Google Sitemaps do not replace Google spidering your site. Google will still spider using its current methods. The Google Sitemap can only help the crawler do a better job because URLs to pages can be listed manually and tagged with other important information.

Benefits of a Google Sitemap

  • Could contain URLs that would be otherwise unreachable via the Google Spider – e.g. if there are pages with no links to them – they can be placed manually.
  • Can list the last modified date of a page.
  • Can list how often each individual page gets modified (e.g. always, hourly, daily, weekly, etc.)
  • Set a priority number (from 0.0 to 1.0) to each page. The priority you assign to a page has no influence on the position of your URLs in a search engine’s result pages. Search engines use this information when selecting between URLs on the same site, so you can use this tag to increase the likelihood that your more important pages are present in a search index.
  • You can have multiple Sitemap files that are referenced via a Sitemap index file.

Limitations

  • Each Sitemap file must have no more than 50,000 URLs and must be no larger than 10MB (10,485,760 bytes). You can compress that file using gzip (http://www.gzip.org/) but the original file must be no larger than 10MB. To list more URLs, you must use a Sitemap index file.
  • Each Sitemap index file may not list more than 1,000 Sitemaps. Therefore, currently, the maximum number of URLs per site are 1,000 x 50,000 = 50,000,000 URLs.

More Information about Google Sitemaps

From Google:

A Sitemap provides an additional view into your site (just as your home page and HTML site map do). This program does not replace our normal methods of crawling the web. Google still searches and indexes your sites the same way it has done in the past whether or not you use this program. A Sitemap simply gives Google additional information that we may not otherwise discover. Sites are never penalized for using this service. This is a beta program, so we cannot make any predictions or guarantees about when or if your URLs will be crawled or added to our index. Over time, we expect both coverage and time-to-index to improve as we refine our processes and better understand webmasters’ needs.

https://www.google.com/webmasters/sitemaps/docs/en/about.html

Example of a Sitemap index file (see that it points to the gzip files):

<?xml version="1.0" encoding="UTF-8"?>
  <sitemapindex xmlns="http://www.google.com/schemas/sitemap/0.84">
  <sitemap>
    <loc>http://www.example.com/sitemap1.xml.gz</loc>
    <lastmod>2004-10-01T18:23:17+00:00</lastmod>
  </sitemap>
  <sitemap>
    <loc>http://www.example.com/sitemap2.xml.gz</loc>
    <lastmod>2005-01-01</lastmod>
  </sitemap>
</sitemapindex>

Sitemap Protocol – released by Google in June, 2005 (still Beta)

Quote from Google:

“Please note that the Sitemap Protocol supplements, but does not replace, the crawl-based mechanisms that search engines already use to discover URLs. By submitting a Sitemap (or Sitemaps) to a search engine, you will help that engine’s crawlers to do a better job of crawling your site.

Using this protocol does not guarantee that your webpages will be included in search indexes. (Note that using this protocol will not influence the way your pages are ranked by Google.)”

http://google.com/webmasters/sitemaps/docs/en/protocol.html

Sitemap Protocol format

The Sitemap Protocol format consists of XML tags. All data values in a Sitemap must be entity-escaped. The file itself must be UTF-8 encoded.

A sample Sitemap that contains just one URL and uses all optional tags is shown below. The optional tags are in italics.

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.google.com/schemas/sitemap/0.84">
  <url>
    <loc>http://www.example.com/</loc>
    <lastmod>2005-01-01</lastmod>
    <changefreq>monthly</changefreq>
    <priority>0.8</priority>
  </url>  
</urlset>

Also, it is possibly to NOT use the XML format for the Sitemap file and just list the URLs per line. You can name the text file anything you wish. Google recommends giving the file a .txt extension to identify it as a text file (for instance, sitemap.txt). You have the same limitation of 50,000 URLs as before.

Location of Sitemap Files

The location of a Sitemap file determines the set of URLs that can be included in that Sitemap. A Sitemap file located at http://example.com/catalog/sitemap.gz can include any URLs starting with http://example.com/catalog/ but can not include URLs starting with http://example.com/images/.

If you have the permission to change http://example.org/path/sitemap.gz, it is safe to assume that you also have permission to provide information for URLs with the prefix http://example.org/path/. Examples of URLs considered valid in http://example.com/catalog/sitemap.gz include:

http://example.com/catalog/show?item=23

http://example.com/catalog/show?item=233&user=3453

URLs not considered valid in http://example.com/catalog/sitemap.gz include:

http://example.com/image/show?item=23

http://example.com/image/show?item=233&user=3453

https://example.com/catalog/page1.html

URLs that are not considered valid are dropped from further consideration. It is strongly recommended that you place your Sitemap at the root directory of your web server. For example, if your web server is at example.com, then your Sitemap index file would be at http://example.com/sitemap.gz. In certain cases, you may need to produce different Sitemaps for different paths e.g. if security permissions in your organization compartmentalize write access to different directories.

Arguing, Changing, and Making Friends

These are the three recent audio books I’ve listened on the train. One is about the basics of arguing. One is on dealing with change. The last one is what you can accomplish by being friends with people.

How to Argue & Win Every Time by Gerry Spence- This teaches the very basics of arguing. You have to know what you’re talking about well so it gives you confidence. Prepare what you’re going to talk about. Put emotion behind your words to make them powerful – some people tend to give into, not because of the logic and facts of your argument, but the tone and feeling you put out, and how you make them feel. Spence discusses the importance of having rhythm and tone (singing helps) when delivering your message as well as how to argue with an angry person. Good book overall, but I don’t think it stresses enough that sometimes arguing is an art, and you need to be a good communicator and listener first – which can be complicated just by themselves. What good is it if you can argue, but you fumble and mutter every other word? Then you can’t argue because your argument doesn’t carry the same weight. Overall, good intro.

Who Moved My Cheese? by Spencer Johnson, Kenneth H. Blanchard – Great book that discusses predicting change, getting ready for change and dealing with change. This is a quick listen that took less than 2 hours. The values taught here can be applied to any profession. I think one misconception that people have when they read/listen to this, is to believe that that the book is telling you to accept change and not fight it. This is anything but. By “change” it means you doing something about it – whether it is accepting the current situation and making the best of it, or moving on and doing something completely different – it doesn’t matter – but doing something after you release your fear of the unknown and doing something that you’ll benefit from.

How to Win Friends and Influence People by Dale Carnegie – This book is gold. This is the second time I listened to it to remind me of the principles. If you need to work with people, whether you’re a salesman, in management, or even tech, I HIGHLY recommend this.

The Power of Influence

A while ago I listened to the audio book “How to Win Friends and Influence People” by Dale Carnegie. This book is gold. It goes over many techniques to apply to your every day life in order to influence someone and make them like you, therefore getting what you want and making yourself feel good and the other person about it. The techniques from this book cannot only be applied to your personal life, but in the workplace too, especially if you work in sales and management.

Here’s a summary of the techniques.

Street Fighter Alpha III Max

Here’s one of the reasons why I bought the PSP. I’m such a big fan of this game that I gave up homebrews for the PSP just for this. It required you to upgrade to 2.5 firmware, but oh well, I’ll get a GP2X for homebrews.

It’s everything that I expected plus more! Tons of game modes and great network play. The only thing that stinks is the control. It takes a while to get used to, like jumping backwards, blocking downward, and forget about doing a dragon punch. Luckily you can set special moves to buttons, so I set the dragon punch to the left side button. You can also get a special dpad from Capcom. Here’s some screenshots:
