My geocaching stats as of 8.18.2010.

Visit geocaching.com for more information.

JPEG of my finds. I suggest using the gps file in Google Earth so you can move around.

I currently use my Garmin nuvi205w, GPSMap 76 and GPSMap 60CSx for geocaching. My 60 CSx is my new receiver and it buries my 76. I have had my 76 since 2001 and it is a great receiver but the sun has given it a beating over the years, (alot of time in the dash cradle) and is loosing contrast on the display. The 60CSx also has a greatly improved receiver. We are taking about a day and night compairison on birds heard.

The nuvi is used to get to the general location but is not very good at getting my close to the end location. My 76 has performed, or I thought atleast, pretty good until I saw how my son's eTrex Legend was doing on receiption. The 76 was still good enough but I feel like it added to my work on finding caches.

One item that the 60CSx has that the 76 does not is position averaging. This will be handy when I place caches that are under tree cover.

• I can not begin to express my concern that if you participate in Skywarn or storm spotting as a hobby to do it safely. The NWS has on more than one occasion and in Skywarn classes discussed why you need to be safe and why hidding under an overpass is a VERY BAD idea. Please refer to the following article. Here is a link that details what happens and why you do not want to be in an overpass when this happens.http://www.srh.noaa.gov/oun/papers/overpass.html As a hobbiest or a trained spotter, there is no excuse for unsafe activity. It can get you hurt or killed and reflects badly on Skywarn actvities if a person gets hurt, damages property, or gets killed due to unsafe actions. If we want to keep the public safe from bad weather, then we have to play it safe as well.

Computer Virus Stats

I have posted these stats from Sophos and Trend. Computer virii have become an evil we all have to deal with. I can not stress strong enough the need for antivirus (AV) software to be inplace and ENABLED. I have been to customer sites to find AV softare installed but disabled. It might as well not been installed. Email is not the only method which a computer can become infected. You can still (like in the "old days") get virii via floppy disks, cds or even visiting a web site. Even if your ISP provides you with AV scanning on their servers, you should still obtain AV software. AV software is only as good it's updates.

Some of the latest virii to come out are actually using infected machines to send SPAM. Some of the infections can cause a machine to perform badly, others you would not notice this at all. These abusers take advantage of high speed internet circuits. Given the speed that these types of connections provide and a users real usage, you might never know. You might eventually find out the hard way, your isp may terminate your service, email adress may get blacklisted or a wannabe net detective may start sending you threatening messages with colorful content in the body of the message. The SoBig virus family has been suspected of being such a virus. Refer to Wired Article. See The Register article on some of SoBig's behavior. Let me put it to you this way, would you intentionally let someone take over your machine for spreading spam? If the answer is no, why would you unknowingly do the same? One last point, if your machine was compromised, your machine (worse case situation) could contribute to a terrorist attack. You could be sending spam (Viagra ads, porno ads, etc). There has also been mention of hijacked machines storing porno or illegal mp3 files and the owner never knew but could be held responsable.

Please visit my Computer Virus page for more info on why you should be using AV software if you need more information.

• Ubuntu This is now my favorite version of Linux. I have a Dell Inspiron E1505 that was setup to run Ubuntu, or so Dell claimed in June 2007. I am currently using 10.04. You can boot Ubuntu as a live cd so you can play with it without trashing Windows and even use it for recovery like I did with Knoppix in 2007 on my wifes laptop. I have used it for data recovery on multiple laptops that started to have hard drives go bad.
• Knoppix I have used this version of Linux to obtain the data from systems that the HD has gone south in. My wife's Dell tanked a portion if its HD in the middle of the area that system32 was in. You could not boot XP. Booting from Knoppix let me copy her entire Documents and Settings directory to a thumb drive so I could copy it over to the new hd after replacing it and installing XP. I now use Ubuntu just to to frequency of use. Both are Debian based and I recommend either one.

Articles on variuous technical topics. Highly suggested reading

Several years back I found a newsgroup post that explains the use and application of the decibel. I scanned in the document since I could not locate the floppy I saved it to. There may be some formating or spelling errors but the math and overall information is valid.

1/4 wave antenna, a cheap source for 12 volt 40 amp power supplies . Using a pc supply can give you a cheaper source for 12 volts that runs cool and quiet. I suggest the use of 200 watt supplies or higher.
