Do you ever wish you could save files you find online directly to a cloud storage service provider? With this handy new free tool called Cloud Save you can. Cloud Save is available for the Google Chrome browser at the Google Chrome webstore.

After you install the extension in Google Chrome, you will find a new menu item when you right-click or try to download files in your browser. The menu item allows you to send the file (without having to download to your harddisk) directly to popular web-based services including Dropbox, Google Docs, Facebook, Flickr, Picasa, and more. Simply right-click a file, then decide where you’d like to send it.

When presenting in front of an audience, sometimes it’s necessary to pause your PowerPoint slideshow for a few minutes to highlight a point, answer audience questions, or to simply take a break.

Sometimes you need to find out your IP address for networking, troubleshooting, gaming, or tech support purposes. There are two IP addresses you may need to consider—your “external” IP address (the IP address the rest of the world sees to locate your computer or network) and your “internal” IP address (which identifies your particular computer in a shared network). Finding your external IP address is easy.

If you are connected to the web, just launch your browser and type: “whatismyip”, and your browser should redirect you to the website whatismyip.com which will provide you this information for free. To find out your internal IP address, just go to the Windows command prompt, or go to the Windows Start Menu and click on Run, then type “cmd”. Next, simply type “ipconfig” in the command prompt and then look for the string of numbers right next to “IP Address.”
