Is this a great country or what...
OK...Let's get started.
A rocket powered vehicle successfully completed the first step toward qualifying to win a $1 million prize for NASA's Northrop Grumman Lunar Lander Challenge. Armadillo Aerospace's "Scorpius" lander set world records for vertical landings and takeoff flights by flying up 50 meters (164 feet) into the air, maneuvering over to land on a simulated rocky lunar surface 50 meters (164 feet) away, and then rising and flying back to land where it started. The flight included a requirement of at least 180 seconds of flying time. Watch the video from the second qualifying flight here. Armadillo is the first team of three teams looking to nab the prize this year.

With the shuttle retirement looming, you never know if or how often you're going to see this sight again. So enjoy these two videos of the shuttle hitching a piggyback ride back to Kennedy Space Center atop a modified 747. Space shuttle Discovery left Edwards Air Force Base in California on Sunday, Sept. 20 and arrived at KSC today, the 21st. Top, is the 747/shuttle landing at KSC (it gets good about 1:20 in) and below is really pretty footage of the duo getting ready to leave Edwards just at dawn, and the lighting is just plain gorgeous.

A group of MIT students have launched a low-budget satellite to near space, taking images of the curvature of Earth and the blackness of space. Their approach was to use low tech, off the shelf equipment, which included a Styrofoam beer cooler, a camera from eBay, open source software and an inexpensive helium balloon as the launch vehicle in order to do their complete mission launch for less than $150. Total cost? $148. The experience? Priceless, including getting interviewed on CNN and Fox News about their achievement. The best news for the rest of us? They'll soon be sharing an illustrated step-by-step guide on how to launch your own low-budget satellite.

This is a blog with daily tips on how to do something in C# and other programming topics. It aimed to be a resource for beginner programmers.
We recently covered voltage dividers in our Ask MAKE column. In the above two videos, done by our pal Jeri Ellsworth, computer industry legend Lee Felsenstein (member of the Home Brew Computer Club and Osborne designer) explains voltage dividers and how to calculate them. Things get pretty thick by part II and I pretty much got lost, but sharper math heads should prevail. These videos are labeled as "Lessons from Industry Legends." What a cool idea. I hope Fatman and Circuit Girl do more of these in the future.

Facebook statistics show that it has 250 million active users each with an average 120 friends. More than 1 billion photos are uploaded every month by its users, over 70% of whom use applications like games and quizzes in Facebook. Unfortunately, most users don't know the implications of entering personal information, making friends, and playing games on Facebook.
This guide will show what you can (and cannot) do to safeguard your Facebook privacy.
What do you do when your boss, mother-in-law, or a casual web acquaintance sends you a friend request on Facebook? Use Friend Lists. Friend Lists are the foundation of your Facebook privacy settings. Select Friends from the top menu, and use the Create link to create friend lists like Co-workers, Family, College Friends, etc. Your friends can't see your lists, so you can name them whatever you like.
Tip: On your left sidebar, all your friend lists may not show up by default. Click More to see all of them, and drag and drop those you want above the separator.
Click Settings > Privacy Settings > Profile. Select which parts of your profile will be seen by whom.
If you choose Customize in the drop down, you can be more specific. This is where the Friend Lists you created before become really useful.
Also go to the Contact Information tab and choose how you want your contact information to be shared on the Internet.
On the Photos tab of your profile page, click Album Privacy. Here again, you can use your Friend Lists to set the privacy for each photo album.
Note that your profile pictures go into a special album that is always visible to ALL your friends.
Click Privacy > Search to set your visibility when someone searches Facebook for people. This is an important way to safeguard your Facebook privacy. You can also select what will be visible in the search results.
Your actions in Facebook such as comments, likes, appear as highlights on ALL your friends' home pages. You cannot use friend lists here, only turn them on or off.
Go to Privacy > News Feed and Wall and choose whether you want your boss or ex-girlfriend to know that you're in a relationship.
Go to your profile page, click Options > Settings under the status box.
Here you can control whether your friends can post to your Wall, and who can see the posts made by your friends.
Facebook has two types of advertisements: third-party and Facebook. Third-party advertisements are currently not allowed to use your pictures, but there is a setting to disallow it if it is allowed in the future. Go to Privacy > News Feed and Wall > Facebook Ads tab to turn this off.
The Facebook ads shown to your friends are about 'social actions' like becoming a fan of something. You can turn this off at the bottom of the page.
Go to Privacy > Applications, and click the Settings tab and uncheck all the boxes. These settings control what information about you is visible to applications installed by your friends. By default, these are set to visible. This means that your religious, sexual, and political preferences, pictures, etc. are readily available to one of the million worldwide Facebook application developers, each time any of your friends takes a quiz, plays a game, or runs any other Facebook app. This is obviously a Facebook privacy issue.
This is the most commonly misunderstood aspect of Facebook privacy. These settings control what applications installed by your friends can see about you, even if you don't install the application yourself.
Why is this important? Because these settings will not change anything about what you are sharing with the applications you install yourself. For that, go to the next step.
There is no way to control what applications see about you; it is an all-or-nothing affair. Take this quiz developed by the American Civil Liberties Union to check what anonymous application developers can know about you and your friends each time you take a quiz.
The Burton Group's Identity Blog features the Facebook Privacy Mirror, an application that you can use to find out what applications know about you and your friends. If you really want to see exactly what profile data of each of your friends is visible to application developers, Privacy Mirror shows it in detail.
The only thing you can do is to authorize only those applications you require and trust. Go to Settings > Application Settings from the top menu. Change the drop-down from Recently Used to Authorized. Here you can see all the applications you have authorized to get access to ALL your profile information. Remove the ones you no longer need.
Also check the list of applications Allowed to Post and Granted Additional Permissions to remove unwanted ones.
You can easily deactivate your account in Facebook from the Settings page. But deactivation will retain all your profile information within Facebook, including pictures, friends, etc. If you want to permanently delete your Facebook account, click here to submit a deletion request. Note that:
Also, note that once in a while, there is news of a Facebook hack or leak that can expose your information on the Internet. It is better to be safe than sorry by avoiding using Facebook for anything that may embarrass you.
I hope this article gives you a better understanding and insight into Facebook's fragile privacy. Have any questions or concerns? Liked the post? Please tell us in the comments!
