15 Mind-Blowing Featured Images by NASA

The NASA Goddard Space Flight Center is home to the United States’ largest organization of combined scientists, engineers and technologists that build spacecraft, instruments and new technology to study the Earth, the sun, our solar system, and the universe. They are also home to some of the most amazing images, visualizations and videos NASA has to offer! Please do yourself a favour and check out their incredible Flickr page which has thousands of images with wonderfully detailed descriptions. Below is a collection of 15 mind-blowing featured images from NASA. 1. The STEREO (Ahead) spacecraft caught this spectacular eruptive prominence in extreme UV light as it blasted away from the Sun (Apr. 12-13, 2010). 2. This is a mosaic image, one of the largest ever taken by NASA’s Hubble Space Telescope of the Crab Nebula, a six-light-year-wide expanding remnant of a star’s supernova explosion. The orange filaments are the tattered remains of the star and consist mostly of hydrogen. 3. 4. 5. 6.

46 Fabulous Photos of Endeavour's Last Ever Spacewalk May 27th, 2011: the last spacewalk for NASA’s Endeavour astronauts. Here, a fish-eye lens attached to an electronic still camera was used to capture this image of NASA astronaut Michael Fincke (top center) during the mission’s fourth session of extravehicular activity (EVA) as construction and maintenance continued on the International Space Station. Photo #1 by NASA A bright sun, a portion of the International Space Station and Earth’s horizon are featured in this image photographed by a spacewalker during the STS-134 mission. Photo #2 by NASA May 27, last day for Endeavour spacewalkers, NASA astronaut Greg Chamitoff continued to work on the International Space Station. May 27: A portion of the International Space Station and the docked space shuttle Endeavour is featured in this image photographed by a spacewalker, using a fish-eye lens attached to an electronic still camera, during the STS-134 mission’s fourth session of extravehicular activity (EVA). Flight Day 5: May 20, 2011.

You can give your "virtual" wireless network any name you want, and also set the password to anything. BTW, this project is written entirely in C#. Contributors

Home - Matts Technology tech blog » Blog Archive » zxcvbn: realistic password strength estimation Over the last few months, I’ve seen a password strength meter on almost every signup form I’ve encountered. Password strength meters are on fire. Here’s a question: does a meter actually help people secure their accounts? It’s less important than other areas of web security, a short sample of which include: Preventing online cracking with throttling or CAPTCHAs.Preventing offline cracking by selecting a suitably slow hash function with user-unique salts.Securing said password hashes. With that disclaimer — yes. These are only the really easy-to-guess passwords. Strength is best measured as entropy, in bits: it’s the number of times a space of possible passwords can be cut in half. This brute-force analysis is accurate for people who choose random sequences of letters, numbers and symbols. As a result, simplistic strength estimation gives bad advice. The table below compares zxcvbn to other meters. A few notes: I took these screenshots on April 3rd, 2012. Installation The model Data Conclusion
