Well my Invisible Fence Battery Subscription has run out, and I am going to need new batteries soon. While I can say that I am very happy with the Invisible Fence and the installation, however the batteries cost a fortune. For 1 year renewal battery plan, where Invisible fence ships you their batteries, the cost is $49 for 4 batteries. You do the math, you can go about 4 months before having to replace the batteries but they do last about 3 months. I found some instructions on taking the battery apart since the only thing unique about the battery is the housing. About the only thing you have to do is remove the black ring that is at the two prong (contact) end. You can use a small jewelers screwdriver or use a xacto knife. I used a stanley knife and stuck the tip of the blade in between the black ring and the grey housing. Be careful because the ring can fall off and is fragile. The battery is a Duracell 3V DL1/3N, which you can probably get at radio shack. Be sure to place the + end on the inside of the housing and the—(negative) end on the end where the two prongs are. I will post price and pics later.

Shortcuts

A repository for every keyboard secret in OS X. Some of these are well known, some are not. Shortcuts in the Menu category are common rather than universal. This list should continue to grow exponentially over time.

This is a relatively new way to bypass a lock which involves using a key that has been cut to it’s deepest setting and has a modified tip and shoulder so that the key can be inserted deeper into the lock with a little whack which drives the pines vertically. The crazy thing is it only takes seconds to open the lock if you have a bump key. And obtaining a bump key is easy, just obtain a blank key that fits the lock and get a locksmith to cut the key or cut the key yourself with a file. Supposedly this works on 90% of locks and will not leave a trace of evidence. This poses a huge risk for homeowners since homeowners and renters insurance will not cover losses if there is no evidence of a break in. The insurance companies will assume you left your door unlocked. For more information check out these videos and PDFs.

Google has quickly become one of the most well known words in the world and is used by millions daily, including myself. In an advanced database class back in university, we spent a couple of weeks studying the inner workings of search engines, and one topic which happened to come up was data mining using Google. Much to my surprise, out of a class of 80 fourth year computer engineers maybe four or five knew how to use Google to perform any sort of advanced queries.

Google (and many other search engines) has the ability not only to search on keywords, but also using a more “database-ish” query language to really narrow down your search results. Below is a summary of a few of the most useful lesser known features. Note: in the examples, replace cwire.org with your own domain.
