Went out and found the TouchGraph Google Browser. "The TouchGraph Google Browser reveals the network of connectivity between websites, as reported by Google's database of related sites."
It reports the same data Google provides but in a graphic instead of a list. I used the keyword www.interfacebus.com to run the report. interfacebus is in the center of the map.
It looks cool, not that I have time to do any thing with the data~
Following along a previous posting about the slow adoption of new interface bus standards, I have yet another one. Upgrading the page that covers PC104 board manufacturers and separating out vendors that produce only PCI104 cards, I don't find that many companies producing PCI/104 boards.
The attached graphic shows the road-map [up-grade path]. The PC104 standard started out with an IBM XT bus interface in a 90mm x 96mm board format in 1992. Following that release, the IBM AT bus interface was added a few years later. Then in 1997 the PCI bus interface was added to reside along side the PCAT bus, as a new connector. With each upgrade board area was reduced because of the increase in the number of connectors. However; card-to-card transmission speed increased as the interface buses increased their throughput.
The PCI104 specification was released in 2003. The change here was to leave the PCI interface, now common, and remove the connectors and interfaces dedicated to the out-dated PCAT bus which than freed up board space.
Odd that there are still not that many PCI/104 board vendors. The stack height is reduced form 6 cards to 4 cards, but they may still be stacked using the PCI104 standard. Could it be that the CPU card is the only CCA that requires a PCI interface, while all the other I/O cards don't benefit from being redesigned? Maybe the increased density of FPGAs compensated for the reduced board area? Perhaps most OEMs require a 6-card stack in a PC/104 chassis. What ever the reason, the original PC bus lives on......

Get a lot of e-mail from other sites wanting to link exchange, most are all spam. The most common type are asking to link to one site while they have yet a third site link back to me. The two e-mails today called it one-way linking, or triangular linking, it's a scam. They want a link from me [A] to point to their site [B] to improve the page rank of 'B'. However, site [C] normally has no page rank and does not help [A].
Link exchanges should be from 'X' to 'Y' and then 'Y' to 'X'
Site 'C' is what is called a link farm, and normally will not do your site any good. Also 'B' never even points to 'C' and my be a third party site altogether. The over all purpose of the scam is to get sites pointing to 'B' with out 'B' looking like a Link farm.
My response is to hit the Report Spam button in G-mail. Stay away from link farms!
Google has a couple of different indexes, its main index and the supplemental index. Google considers pages in the supplemental index as less important to normal pages. Or its nearly impossible for pages in this index to be returned during a search unless very few other pages match the search criteria. interfacebus has 136 pages in the supplemental index, out of another 1,230 pages in the normal index.
Many of the pages in the supplemental index are orphaned pages [old pages no longer used], and 'Bad Address' pages [pages that redirect misspelled addresses]. However many pages are also normal pages with no real issue and really should not be listed there. Here are a few of the pages:
Military D-Sub Connector Manufacturers
Stepper Motor Manufacturers
Linear Actuator Manufacturers
Circuit Breaker Manufacturers
Real Time Clock Manufacturers
CompactFlash Card Pinout
This is just a few of the pages, most don't have a page rank. One reason for ending up in the supplemental index ~ the page looks like another page. This is common to have near redundant content; for example when the Linear Actuator page was started using the Motor page as a starting point.
It appears it's getting a bit harder to determine which pages are listed in the supplemental index, this is the command I used to determine the page listing;
site:www.interfacebus.com/&
Just figured I'd post a graphic showing how one of the many different things Google Analytics provides in terms of data. This one shows the Visits-site-overlay, who clicks on what link.
A bar is provided under every link on the page indicating the percentage of people clicking on that link [that's the home page]. In this case the Google Search bar is high lighted.
So on any given page you can tell how the traffic moves about your site. All the links still work in this mode, so you can still click a link and see how the traffic moves on the following page...
I came across a page on the site yesterday that does not yet have a Google Page Rank. The page covers RF Phase Detector Manufacturers. ~ Not very well because the page only lists one manufacturer.
Any how I always assume waiting 4 months to receive a page rank, maybe 5 if the spider is running late. The 'Last Modified' date on the page is 3/17. All the other pages in that section already have a ranking: RF Device Manufacturers.
The Phase Detector page shows up in a Google search so I know its been spidered?
Of course all the new pages added with in the last few months don't have a page rank either, but I expect that.
I was out looking at Google Site map yesterday.The Diagnostic tab indicated there were 20 URL's not found. Eleven of the bad URLs were new pages ~ the reason for up-loading the new sit map.
Any way, those pages all used spaces in the address. I don't use spaces in the URL, so I must have been in a hurry when I generated those page addresses. So I changed the name adding dashs in place of the spaces and re-uploaded the files, leaving the original files out on the server.
Now Google indicates I submitted 1405 URLs, while the previous up-load indicated 1359 URLs. I had generated a few new pages, but I don't recall making 40. Maybe GSiteCrawler didn't like the spaces either.
Hmm; The programs Statistics indicate:
Number of URLs listed: 1406
Number of URLs to be crawled: 1061
Number aborted: 2 [checking those errors now]
Because the crawler puts a heavy load on my server, it has to pull every page. I only run GSiteCrawler on the off-hours.
The attached pic shows incoming visits from Virginia so far this year
For the last three days AWStats has been down, I just return a server error page. AWStats is what I use to track hits to the web site. The attached graphic is from Webalizer which is the other server side counter that provides data; however I like AWStats.
I just submitted a trouble ticket.
In addition to the two server side tracking programs there are two additional programs tracking web site data. Google Adsense provides page views, and Google Analytics which gives all sorts of data.
Webalizer indicates [for Aug] that there have been 2,294 Internal Server Error codes returned [Code 500].
Hmm blog hits are down. Could be more people are reading the RSS feed rather than the blog it self. Google reports only 22 hits for Sunday and no hits for Monday, as of 7pm.
This first graph is subscribers, while the second chart is visitors.... Both pictures are from FeedBurner.
Hurricane Dean is out of the picture at this point. A partial back-up was completed to Flash Drive. I still need to back up to CD, but I have a 1GB Flash drive ready as well.
I never rely on the server as back-up only because there is no was to guarantee what version of any page they may have.
I came across a file today that was generated in March but was not on the server. This is common, many times I'll up-load a group of files to the server only to find that half of them didn't make it. The bad thing is that because I don't want to skew my stats I don't check the pages that were just up-loaded.
One more map, this time showing the details from Florida. The largest incoming visits [hits] are from Orlando (13,337), Miami (10,243), Tampa (9,959), and Melbourne (7,815). The figures are from mid last year till today. I signed up for Google Analytics in April 5 2006. Additional data for the state:
Total Visits: 64,096
Pages/Visit: 2.28
Average Time on Site: 7:20
Percent New Visits: 70.79%
Google Analytics really provides a lot of data. I recommend using it. A few lines of code are required to be added to each page.
I made a few new pages over the last few weeks so it's time to generate and up-load a new site map to Google. Part of Google's Webmaster Tools, Google sitemaps allows a web site to generate an XML sitemap of a site and up-load it to Google. By uploading the XML file, Google is informed about all the pages within a site. In most cases this is faster than waiting for GoogleBot to come by and spider the new page.
I assume, based on the number of pages that get spidered daily, that a spider will find the new page within 15 days. Maybe the spider will find it in 30 days worst case.
Because it takes 4 months to be assigned a page rank by Goolge it's always better to get the new page noticed as soon as possible. Also the faster the page gets spidered the sooner it will show up in a Google search ~ web search and site search.
I use GSiteCrawler to spider the site and generate an XML Sitemap which I then upload to Google. I also link to the site map from the Robots.txt file so all the other search engines read the map as well.
This XML site map differs from the sites HTML sitemap which is generated from Xenu. The Xenu application is used to spider the site and report on broken links, it just happens to also generate a list of all the pages on the site as part of its report I use that portion of the report to produce a sitemap page for interfacebus.com. That sitemap is located out on the Google Page Creator section of the site.
The Google cache reports 1,220 pages for interfacebus.com. The previous site map up-loaded on April 29 shows 1,346 pages. So not all pages have made it into the listing yet. This crawl from GSiteCrawler indicates 1,360 pages. So 15 pages have been added over the last 3 months. This second graphic is a zomed in version of the first picture, showing just the hits coming from the US.
Looks like Tropical Storm Dean is moving west past Florida. So if Dean hits this site it should be coming from across the state which means just strong winds.
Standard procedure is to back-up the system. Consolidating the folders so files in folders that don't get backed up are backed up. Saving the files both to a Flash drive and to the Laptop PC that would travel on the evacuation.
Don't rely on the server for storage. If the server crashes the site provider may re-load from a back-up. However; the server may re-load older pages, out-dated pages. So, it's always a good idea to be ready to have up-to-date files to re-load to the server.
PCI Express has been out for a few years now and there are a fair number of PCIe 16x board manufacturers. What seems to be missing is 1x card manufacturers. interfacebus has only accounted for 6 different companies that produce 1x boards.
LXI is another new standard which came out in 2005 for industrial use. However; only 2 companies have been located that produce LXI gear.
Yet another industrial specification released in 2005 was PXIe. The PXIe is the PCI Express version of the PXI standard. PXI is the Instrumentation version of cPCI. Compact PCI is the industrial version of PCI.
Released in 2006; Compact TCA [cTCA] is another one with out many vendors yet......
There are many other new standards that have been coming out in the last year or so. Most are off-shoots of old standards that are beginning to adapt the PCIe interface [Industrial Board Formats & Manufacturers].
It's been a dozen days since signing up for RSS using Feedburner. The chart shows the subscribers per day for the last few weeks. Google reports a slight drop in blog hits which could be due to users reading the blog via the feed, and not going to the physical blog page.
I assume this is new subscribers per day, but it may indicate users reading the feed per day ~ I have no idea. The low is 8 subscribers, with the high is 12; Sunday 8/13 [dark green].
By signing up for a feed the blog risks losing ad revenue, but may gain some via increased visits ~ it's a risk.
I don't use a counter for this blog. I use the Google AdSense reports from interfacebus.com. So the Feedburner stats provide data on pages viewed, origin and so on. This blog is "in the noise" compared to the web pages of www.interfacebus.com. This blog may get 1000 hits a month while a single page on the web site may get 8000 a day. I'm not even sure the report gets to a page that only receives 50 hits a day ~ it's truncated.
Interestingly I see that this blog has hits from around the world and hits to pages that were written a year ago
Looking over Intel's site today and came acrossed a few pages dedicated to Moore's Law ~ the amount of transistors doubles ever two years. Current Intel processors have over 500,000,000 transistors, or over 1,000,000,000 for a dual core.
Much of that is redundant circuity, one small memory block used again and again to build a large buffer for example.
Even so these processors are large design efforts, with a 100,000 circuits
The web site past the 1,000,000 page mark some time yesterday with 1,009,338 unique views ~ according to the server counter. Google Analytics reports 1,092,341 unique visitors with 2,827,189 page views
This is a chart for http status codes returned from the server hosting interfacebus.com for the month of July. There are a dozen or so pages that have been orphaned and moved to a new page address; however, those old addresses still get traffic [code 301]. The 'Document Not Found' or 404 code normally comes from people linking in or typing in the wrong page address. I try to catch some of that missed traffic by generating a page with the incorrect address ~ if it's getting traffic. Many mis-spelling can't be corrected, as they are missing the ".html" at the end of the address. There are 115 pages that target bad page addresses....
The server issues, codes 404 and 500, are just that ~ problems with the web server. Not sure what code 405 is?
Over looking at the Google Analytic data for interfacebus.com. I find that so far this year 43.68% of the visitors are from the
Total visits so far 1,321,240 [from 222 countries]. With 2,746,725 page views.
The interesting thing about the map, there are five countries that have not used the web page this year ~ guess they don't have an internet [countries in white]. They are
