Happy Holidays!


To find a lost page that is not very old, look in the Google cache. Go to http://www.google.com/. Type a complete URL into the search box

How can you find a missing web page? There are several things you can try to find a missing web page or link. A missing page is usually indicated by the web error message 404 Not Found, returned when the URL is misspelled or the page no longer exists. The first 4 indicates a client error, the 0 a syntax error, and the final 4 that the problem is a page not found.

Character case. Domain names are usually not case sensitive, but URL path descriptions sometime are. Make sure that the page address has the same mix of upper and lower case as specified in the URL where you originally found it.

Site can’t be found. If the error message says that the whole site can’t be found, then either the site address is misspelled, the original address was wrong, the site doesn’t exist, the site hasn’t yet been registered with the Internet domain name servers, or the site has been closed down.

Port number. If a site URL includes a port number after the domain name, then different ports might have different sites associated with them. Try dropping the port number, or changing it to 80 or 8080, and see if the same or some related site is found.

Reference Check. Check to see if the address ever did exist by searching for the url on a search engine, and if it isn’t found (i.e. no search engine picked it up, and no other page ever linked to it), then you may have the name misspelled or the original reference was wrong.

Moved page. If the page can’t be found but you are sure it did exist, then either the page has been moved somewhere else on the site, moved to another site, or closed down. You can try the following techniques to try and retrieve the data:

Unique reference. If you know of any unique reference on the page that would not be on any other page, such as a unique title, name, or quotation, you can try searching the web as a phrase to see if anyone else has posted the same material.

Related information. If all of the above steps fail, then you are left with the option of related information. You can search on keywords you think would be on the page you were looking for, which will generally return pages with similar types of information, and may also provide the information you were looking for.

You can see if there was a website and what might have happened to it at Netcraft.com. They will even give you the history of the site and the hosting company for the site. sometimes you can contact the hosting company to see what happened to the site. It is also very useful when examining phishing emails to see where originated.

Linux tools

See if the website is alive.

What happens when computer people get together much like old car talk. What’s in you machine? You want to say more than I don’s know. The newest devices such as the touchpads, some netbooks, and etc. today are pretty much unfortunately throwaways. As for desktop computers,  at least for a while you can upgrade them. It is very useful to know what equipment and and in some cases what software is on the inside. For insurance purposes, you would be well advised to have such a list tucked away in a safe deposit box or where ever. So I went on a little research expedition to find out what might be used to find out what is in my computer.

OS/X: (textedit to view)

You can go to the system profiler and output a text list of the hardware.

A script for older systems: http://richardspowershellblog.wordpress.com/2007/07/21/hardware-reporting-script-vbscript-and-powershell-versions/

For MSWindows 7, I am told you can use the Devcon utility to print out to a file of the hardware. More information at:

The new file cabinet or what is called network-attached storage (aka nas) is very useful for a business. Network-attached storage is a computer(s) that are dedicated to acting like an external hard drive for your computer network. Not that you could not share files from your local machine, the nas allows more than one person access under certain rules load and save files to the unit. It is basically a computer dedicated to serving out files. Just a new name or buzz word for a traditional file server. Nas units are generally oriented to the home or small business where management or administration of the file server is or can be reduced.

You can get a nas in what is called a turnkey package off the shelf from your local electronics store. Generally you might pay a premium for such a setup. But then you know it should be supported well from the manufacturer. Hewlett Packard is a prime example of those units. Now everyone under the sun is selling some sort of system billing themselves as a nas unit. Not saying that is bad, but you do need to compare the features.

Could you use a spare machine to do the same thing? You certainly can. In fact, using a spare machine can save you money and maybe even time. There are a lot of commercial packages you can purchase to get the job done. Any brick and mortar computer store can tell you what they recommend. Being a supporter of open source, I would recommend using linux , but if you are not familiar with Linux that can as much work as some of the commercial solutions (unless your an IT specialist).<br />

What do I use? Definitely use linux as you can add many other services that the traditional nas may or may not offer. What i like is something call FreeNAS. It is based on FreeBSD and is a cousin sort of to linux. Even the Apple osx is based loosely on BSD. As in the name it is free, so there is no shelling out of hundreds of dollars to make a pc a file cabinet (unless you want to contribute to the project). You can find FreeNAS at “http://www.freenas.org/

What is so great about FreeNAS? They have two versions, one for newer computers (version 8) and the also have a version for legacy computers (version 7). It can be set up in minutes by a knowledgeable user. It can even be run from a cdrom or even a simple thumb drive. You could easily turn an existing machine into a nas. I think I set up mine in a total of ten minutes. Another advantage is that you can use already existing drives without reformatting them. For example, we took a drive from an old Microsoft windows machine with lots of files and plugged it in (with the machine turned off)&nbsp; and FreeNAS was able to immediately recognize the drive and immediately put to use the existing files so they could be shared on the network.

Now if you want more advanced features (such as a commercial nas may offer) of a nas such as a raid (redundant array of independent disks), you will need to use drives that can be erased or wiped. So you would need to back up the MSWindows formatted drive we used first. Raid depending on what level you use can allow you to replace a failed drive on the fly and the system will repair it self.
In recent years, FreeNAS has added other feathers such as a web server, the ability to support iscsi (independent small computer system interface) devices, and many other features. FreeNAS is more than a one trick pony.&nbsp; More on that at a later time. The main advantage of FreeNAS, I like is that you can manage it remotely via a web interface. All a simple point and clicky type environment.
Only you can decide what file cabinet is best for you, but FreeNAS should be included in your decision making process.


You will probably see enough food this week.

Good day.
