How to make strong, easy-to-remember passwords http://news.cnet.com/8301-19518_3-10310092-238.html?tag=mncol;posts By Larry Magid Larry, the algorithm you promote requires WAY too much effort, especially when you're talking about maintaining complex passwords for dozens of sites we all have to log into. Online password managers simply require too much effort, too. Also, many sites limit the password length, so you can't have a really long sentence-style passphrase.
What I've found that's worked for me - and my day job is as a process efficiency specialist - is to use some form of the site's name with some form of a relative's name. This means every password is different yet similar enough only to me and no one else. For those sites that require passwords to have a number in them, I've selected a number and place it in the same spot.
Due to the algorithmic beauty of this system I don't have to keep any records at all, yet I can instantly determine my password for any site, and no one else could ever guess it because even though you now know the concept of the algorithm you could never determine the specifics of it.
Another way to make a decent password is to pick a pattern on the keyboard. i.e. cvfder43 (type it and you'll see the pattern). I looks like gibberish but is easy to remember. Don't pick a pattern that goes in a straight line, give it a couple of turns or jumps. For those that have to change passwords on a regular basis, all you have to remember is where to start on the keyboard.
Science has created a new sweet detecting device that is the size of a business card. This card has sensor that can detect 14 different type of sweetener, from natural sugars to artificial products such as Splenda. The lead researcher says that it works just like a litmus paper, when it is dipped into food or drinks it produces colored dots according to the type of sweetener. This new creation attracted the attention of many food manufacturer as it is cheap and not time consuming. However, the scientist have a much bigger goal is creating a device that does not only detect the sweetness but also other taste such as salty, sour, bitter and umami, just like a human tongue can detect.
Homework regarding the NASA Website I choose topic "Exploring the Environment" NASA sponsored new future classroom learning to replace local classrooms. Today the classroom of the Nasa are providing elearning education to both teachers and students through NASA website. The exploring the environment program develop students awareness through learning about our planet. through this website it provides various module and activities in exploring the environment put students in problem based learning scenatios based on actual situations. The modules available in this website such as weather, population growth, bio diversity, volcanoes, water pollution and global warming. Through this website it helps both students and teachers to make better choice for the future by understanding today impact on this earth.
I choose the topic of "International Space Station Challenge". The article told us the better way to study microgravity and the effects of long-term spaceflight than in space itself? That's part of the mission of the International Space Station (ISS) as it circles Earth each day. The ISS Challenge™ website uses the space station as its backdrop to create activities in life science, physical science, and engineering
Farming in Space: Students from kindergarten through high school can work online or in a laboratory to research, design, and run plant growth experiments. The research parallels experiments flown on the International Space Station.
From Ponds to Oceans: Middle school students (5-8) learn key concepts of populations and ecosystems by performing laboratory experiments and working with images taken from the International Space Station by EarthKam (Earth Knowledge Acquired by Middle School Students).
Trip to Mars: Middle school students (5-8) learn physics and gain math and inquiry skills as they plan a manned mission to Mars. Students perform laboratory, field, and computer-based activities and simulations while studying Newton's laws of motion and compare three propulsion systems: a chemical rocket, a plasma rocket, and a solar sail.
Electricity and Power in Space: High school and middle school students (6-12) learn electricity basics while performing computer simulations and hands-on activities. Students use Ohm's law to calculate current, voltage, and resistance in a math-rich environment. In the final challenge students act as NASA engineers, applying the concepts they've learned to solve a realistic problem.
Create a Full-Scale Layout of the ISS: Although it is difficult to imagine, the International Space Station when completed will be longer than a football field. This activity gives students (grades 5-12) a feel for the actual dimensions of the ISS as they work in teams to assemble a full-scale two-dimensional outline of the ISS.
Analyzing interactive activity communication in online courses to determine the evolution of online communities of learning by Bubb, Terri Edwards
With regard to distance education, student engagement, and social interaction there lies tremendous potential concerning adult learners and their achievement. Each of these domains seeks to empower individuals towards improving their overall academic success. Surprisingly, approaches that investigate distance education, student engagement, and social interaction in higher education have received very little attention (Biocca, Harms, & Bugoon, 2003; Mellon & Kestor, 2004; Palloff & Pratt, 2005; Russo & Benson, 2005; Tu, 2002; Tu & McIsacc, 2002; Vesely, Bloom, & Sherlock, 2007). The majority of effort focuses on establishing the distance education course infrastructure and providing training on constructing a distance education course (Molinari, 2004); yet once the course environment is developed, the question should turn to appropriate instructional strategies to actively engage learners that supports higher order thinking skills (Bloom, 1956) that are integral towards understanding a real world environment. As distance education courses continue to expand in higher education, questions surrounding the creation of a dynamic and successful community of learners must be addressed (MacDonald, 2002; McIsaac, Blocher, Mahes, & Vrasidas, 1999).
The purpose of this qualitative study was to investigate what factors contributed to the formation of a community of learners in a distance education graduate course. Eleven students and one instructor in an online Master's degree program at a higher education institution were studied. The research question that guided the study was: What are the factors that may contribute towards creating a community of learners within an online environment? A design utilizing case study and grounded theory was used to define emergent themes. Archived data were collected that included bulletin board posts, student assignments, emails, and student e-folios. Five major themes were identified from the data analysis which included 24 categories and subcategories. The results identified certain elements which may lead to the creation of online learning communities. These elements were discussed in detail and recommendations on creating and maintaining online learning communities in higher education were made.
