W3Who is a web service which facilitates information from websites, even when the “whois” feature is private. Typing one site, w3who will return all the sites registered from the same owner.

W3who maintains an indexed and large database of adsense and google analytics publisher, making really easy to identify website networks. So, for example if you are working on a startup, using w3who can make an interesting research about the competition.
Even more, you will also receive some other information about the site: server IP address, server location, websites hosted on the same IP and similarly targeted sites by keywords.
Prey Project it’s pretty cool software created for users who want an effective way to locate their devices in case they get stolen. Prey can be installed in Windows, Linux, Mac or any device with Android OS, including smartphones.

Prey can notify users about the device location sending a signal over the Internet, or SMS in case of Android phones. The program runs as an agent in background and is completely silent. Here are some of the specs:
- Open Source and completely free.
- 100% geolocation aware. Prey uses either the device’s GPS or the nearest WiFi hotspots to triangulate and grab a fix on its location.
- Know your enemy. Take a picture of the thief with your laptop’s webcam so you know what he looks like and where he’s hiding.
- No unauthorized Access. Fully lock down your PC, making it unusable unless a specific password is entered.
- Wifi auto connect. If enabled, Prey will attempt to hook onto to the nearest open WiFi hotspot when no Internet connection is found.
- Watch their movements. Grab a screenshot of the active session.
- Scan your hardware. Get a complete list of your PC’s CPU, motherboard, RAM, and BIOS information.
- Light as a feather. Prey has very few dependencies and doesn’t even leave a memory footprint until activated.
- Keep your data safe. Hide your Outlook or Thunderbird data and optionally remove your stored passwords, so no one will be able to look into your stuff.
- Full auto updater. Prey can check its current version and automatically fetch and update itself, so you don’t need to manually reinstall each time.
Pet Finder is a website which has been running for well over a decade helping to find homes for animals and to educate owners and potential owners. It’s owned and run by a very reputable media company called Discovery who operate the Discovery Channel network and several other media forms.
