Google Sitemaps

I ran Gsitemap again today and again it only reported about 938 pages. So instead of spending hours trying to figure out which pages were missing I went ahead a down loaded a new program. This new one is called GSiteCrawler. It seemed to work really good, as it found 1346 pages out there which is more than the 1206 pages I link to. GSiteCrawler did show a pop-up that it would asked Google what it showed for my site, so I assume it pulled in some orphaned pages and page redirects I have posted. The page redirects handle misspelled page addresses I see coming in from any number of forums.

Any way I will not know for sure if it worked right for a few hours or days. I also fixed a bug in my robots.txt file to correcly show the location of my sitemap to other search engines.

Wow, Google has already started reading the sitemap file, and agrees that there are 1346 submitted URLs ~ that's a good thing.

GSiteCrawler also produced a normal HTML siremap I could list on my web site, but the page address are not in alphabetic order ~ Maybe in the order they were spidered?

Hybrid Hard Disk Drive

Hybrid Hard Disk Drives are about the hit the market. Hybrid Hard Drives or HHD use either 125M Bytes or 256M Bytes of Flash memory as a cache to speed data thru-put. HHD devices are also set up to spin down the platter to save power as the data is only retrieved from the Flash memory.

Normally Hard Disk Drives only have a maximum of 16M Bytes of cache memory, so HHD come with at least 7 times more memory.

I don't list any manufacturers for Hybrid Hard Drives yet, but I'll start adding them as they come to market. I would assume that HHD devices will have an SATA interface.

DDR3 DIMM Memory

DDR 3 memory should be showing up soon in stores. DDR III is the third generation in the Double Data Rate series. DDR3 runs faster than DDR2 which tops out at 800Mbps. DDR3 will double that transfer rate and consume less power because it operates with 1.5 volts instead of 1.8 volts.

DDR4 is not due out until 2011, while DDR2 arrived in 2004. I've seen that the AM2 processor socket from AMD does not support the DDR3 memory. Also that the next new processor from AMD, called AM3 will not be released until 2008. However it would appear the an AM3 processor will work in an AM2 socket-ed Mother boards. Here are a few links:

Getting Listed on Google

There are a number of ways to get litsed on the Google search results:
1. If you blog, use Google Blogger ~ you will show up in a blog search and maybe a web search, but that depends on the key words.
2. Use Google Page Creator, for your web site. That's a Google site, so you will show up in a Google listing
3. Use the Google add a link to insert your link to the Google data base. Add your link to dmoz regardless.
4. Hit the Suggest a link out in dmoz.
5. Use Google Site Maps to get your site listed

Google Analytics Report

One of the reports that Google Analytics provides is a graphic of a page and the percentage of what link is clicked on. So for people reaching the index page of interfacebus.com these are the odds that one of the 8 main links are visited

Part Distrubutors = 1.99%
Components = 12.61%
Equipment = 3.85%
Software = 2.42%
Standards = 8.08%
Buses = 12.06%
Design = 4.90%
Reference = 4.59%

Pushing into the Components page, I find the follow click-thru's;
Semiconductor = 26.34%
Passive = 11.29%
Mechanical = 10.0%
Alphabetic Listing = 4.37%

Pushing into the Semiconductors page [three levels deep], I list the top 5 clicks;
Memory = 7.35%
Specialized IC's = 6.95%
Programmable Logic = 5.92%
Standard Logic = 5.05%
MicroProcessor = 5.04%
FETs [General] = 4.32%

Pushing into the Memory page [four levels deep];
Flash Memory = 8.46% [I just up-dated that page]

Checking my server stats:
Memory = 790 viewed pages for April
Specialized Logic = 153 viewed pages for April
Programmable Logic = 227 viewed pages for April
Standard Logic = 263 viewed pages for April

So the drill down from index to a specific page, does not tell how often a page is visited. I could spend days looking at these reports. This is one example of people finding my index page and clicking the links to get to the page they wanted, one example. I have 1200 pages, or 1200 different ways for a person to navigate the web site. Most visits start at some page other than the index page.

Site Traffic

Its been a while since I've posted the graphic showing the site traffic to interfacebus.com
The graph shows Unique Visitors to the site. A separate person showing up, and not re-counted if they come back.
Other stats; 'Number of Visits' = 1.32 visits/visitor, 1.89 pages/visit, 14.71 Hits/Visit

The chart covers Jan. 2001 to March 2007 with the highest point being 149,184 Visits in March. The large dip in 2005 occurred when I changed the site counter to my server.

More site data my be found on the FAQ page. So the site is still growing, and while being at a Page Rank of 5 for the last 8 months [after years with a PR of 6].

Total page impression for the year: 1,152,577.

AMD Pricing

The price for AMD processors are at an all time low. I saw an article the other day indicating that AMD had reduced your prices around 40%. So I got around to checking.

I pasted their list of dual core X2 processors as of today. I omitted the FX series [high end gaming PCs] and non-dual core [budget PC] series to keep the graphic from becoming to large. I assume these prices are in lots of 1000, and I don't think the PC makers are passing on the price yet. I would think they have a inventory to draw down first.

I think it's almost time to get a new PC, with a Dual-Core AMD processor..

Google Crawl rate

Here is a graphic for how Googlebot crawls the web site for the first 4 months of the year, interfacebus.com at an average of 325 pages a day, and a maximum of 723 pages crawled in one day. The site has around 1200 total pages. Click on the image to view a larger picture. The left axis shows the number of pages crawled per day. The top display shows the first three months of 2007. There are at least 48 other spiders [robots] that visit my web site.

This next graphic shows Apr to July of 2007, which was added 8/3/07
