Hello,
My 2nd Android app is being released on Google Play today.
GradCalc is a simple utility to find out when a student will graduate. It targets the 2014-2015 school year, so it will be good for making user accounts for students over the summer and into the fall.
Great for K12 admins who need to make user accounts as they can quickly check the projected graduation year based on grade level.
Please test on my app on your device and let me know if you find anything strange. I would greatly appreciate it.
The app can be downloaded from the Google Play store here:

Thank you all so much!
Michael

Windows Command Prompt Shortcuts/Time-Savers
You can get a lot done on the command prompt in Windows. Quickly getting a command prompt open in windows in the directory you need can sometimes take a while depending on how deep the file structure goes. Luckily, there are a few quick and cool shortcuts to make life easier.
In Windows 7, there is the open command prompt here feature. This lets you right-click on a folder to access a command prompt that points to that directory. To try it out:
Hold shift and then right-click on a folder and this will bring up the sub menu and you will see that an option for open command prompt here is now listed:
Another cool trick is to bring up the explorer window for the area you want a command prompt in and simply type 'cmd' into the address bar. This will open up a command prompt in the current path you're in. For example, if I was in My Documents > My Games folder and went to the address bar and typed in cmd and hit enter, the command prompt would automatically appear targeting My Documents > My Games:
Sometimes it is necessary to run the command prompt as admin. Try this next time you need to:

Another time saver for administrator command prompt would be making shortcut to cmd and then right-clicking it to bring up the properties. Look for the advanced button on the shortcut tab and check run as administrator. Awesome.
Hopefully some of these tips will come in handy for you. I would also recommend checking out this great resource - An A-Z index of the Windows cmd command line at:

Sharper Image Apple 30-Pin to Lightening Adapter
Found this tonight in TJ Maxx and figured it was worth picking up.
It is a Sharper Image 30-pin to lightening adapter for Apple iPhone 5, 5S, and SC. They had it with all of their phone accessories. It is priced at $7.99. Not a bad deal at all considering I have a bunch of 30-pin cables laying around and only a few lightening cables.
The unit is very light and small which is good because it can be carried around in your pocket. The build quailty feels good on it as well.
I did try hooking the adapter into my iHome and while it charged, I was not able to get music to play directly from the iHome speakers while plugged in. I will have to look into that though, but for $7.99 being able to make use of all the extra cables I already have will still be worth it to me. If interested, I would check out your local TJ Maxx while they might still have them around.
