Verizon Network Extender

I was really stoked when I heard that Verizon was going to release the Verizon Network Extender, a femtocell device for directing cell phone traffic over your broadband internet connection. I live in a very rural area, and cell service at my house is non-existent. When I decided to order the device, there were not many user reviews on the web yet, however there does appear to be a few on CNET now. I decided to give it a try anyway, because as an existing Verizon Wireless customer with no service at home, it seemed like an obvious choice.

The Extender has been hooked up for a few days now, and so far it has been working great. Installation was simple, and phone calls have been crystal clear. My phone went from literally no service to four bars. The signal is strong throughout the entire house, including the basement and garage. If you’re interested, Verizon has a helpful installation video here.

If you live in cellular ‘dead zone’ like I do, I highly recommend the product.

iPhone-a-licious

Up until now, I hadn’t jumped on the iPhone bandwagon. However, yesterday I was listening to an automotive podcast, and they mentioned a new iPhone app called Dynolicious. You install the software on your iPhone, and then place the phone in your car while driving. The software can then be used to calculate the car’s performance statistics, such as 1/4 mile ET’s, 0-60 times, horsepower, etc. While, there are devices (such as the G-Tech) that can calculate these statistics, they can’t be used to make calls, take pictures, play music, surf the web, etc., etc., etc.

Hearing about this software was one of those “blow your mind” moments for me. It is an amazing application of the iPhone’s technology, and also made me think about just how powerful the iPhone is. It will be interesting to see what other creative applications will become available for the phone. Gaming possibilities could be a huge use of the technology. While it’s not exactly a Nintendo Wii, tapping into the accelerometers could lead to some exciting gaming on the small screen. After a quick look at the iPhone app store, and it looks like there are already a few games that utilize the accelerometers, but it could be fascinating to see what else is available in the upcoming months.

It might be time to go phone shopping this weekend….

Formatting my MP3 player

My current MP3 player is a SanDisk Sansa c250. It’s not a fancy as some of the more expensive units, but overall it’s very nice unit for the price. Recently I needed to transfer 1GB of data between to pc’s and didn’t have a flash drive handy; so I just copied the data to my Sansa and used it for the transfer. This seemed like a good idea at the time, but when I tried to delete the data from the MP3 player, I was faced the the error message “Folder cannot be deleted because it is protected.”. After some experimenting, it looks like the Sansa will not let you delete a folder if it contains data. This wouldn’t be a big deal, except that the data I had transferred contained hundreds of folders. There was no way I was going to dig through all of these folders to delete the files. Being a developer, I decided to automate the process and write a .NET application that would traverse the folder structure of the unit, and delete all of the files.

I threw together a quick app, tested it on some other folders, and was off to the races (or so I thought). I attempted to select the folder on the device (using the .NET FolderBrowserDialog), and Windows Vista gave me the error message “The folder cannot be used”.

I had never tried to access a portable device programmatically, so I wasn’t sure what the cause might be. Google’ing didn’t help. Next, I did some debugging to find out what the referenced file path was so I could just hard code it. The path turned out to be in Temporary Internet Files. I’m not quite sure what this means, but obviously Windows doesn’t treat this device like a normal drive.

It was time to take a step back and think about what I was trying to accomplish. I wanted everything deleted from the device, except for my music. But, all my MP3’s are backed up on several devices. I took a quick look at the options on the Sansa, and it turns on there was a format device. This quickly wiped out everything, and then I simply copied the music back to the device.

I guess sometimes, it pays to approach a problem from a different perspective.
