ANDROID PICTURE PASSWORD

Android has seen different kinds of lockscreen from the first time it hit consumer devices, there is the face unlock, pattern, classic code unlock, etc. Now an XDA developer kevdliu has come out with an application which replicates Windows 8 picture password lockscreen, but also has added many amazing features to it.



Now, this is the next level of security for your mobile devices, until the iPhones finger print scanner is made into use. You can select a custom image as your lockscreen and customize that image by selecting a point and then drawing gestures or lines from that point. Now you have to always press that point and do the customized gesture every time to unlock your device.
This application is really easy to use. You just have to select a background image for your lockscreen and then put in the gestures and customization, the application also allows you to test out your gesture to make sure that you get it right.
The pro version also has options for screen lock delay, start in boot and toast message options.
You can download this application from Google Play store.

INDIA FIRST 4G MOBILE PHONE

Bharti Airtel and Huawei have teamed up to unveil what they call India's first LTE TD (4G) smartphone, the Huawei Ascend P1 LTE. The price of the device has not been yet revealed but speculations are it will be around Rs. 30,000.

The Huawei Ascend P1 LTE supports 4G high speed wireless data on the LTE network and voice calls on the 3G network using Circuit Switched Voice Fall Back (CSFB voice) technology. The smartphone runs on Android 4.0 Ice Cream Sandwich OS and is powered by a 1.5GHz dual-core Qualcomm Snapdragon S4 processor.
Other specifications of the device include a 4.3-inch Super AMOLED touch display with a resolution of 960×540 pixels, Corning Gorilla Glass, 1GB of RAM, 4GB built-in storage, microSD card, and an 8MP rear camera with dual-LED flash. The device also supports Wi-Fi, microUSB and Bluetooth connectivity, and ships with a 1,800mAh battery.
"It [4G services] is taking time to ramp up. But it definitely has a wow offer. Right now we are able to offer 40 Mbps of download and 20 MBps of upload speed. The icing on the cake is that the customer pays us around $20 ARPU," says Sanjay Kapoor, Chief Executive Officer, India and South Asia, Bharti Airtel.
Airtel is the first telecom operator in India to launch 4G services. Earlier this year, the telco launched 4G services in Kolkata, later rolled out to Bengaluru as well. Even as 3G coverage gradually expands in India, 4G services, according to an estimate, are estimated to reach 5 million users by 2013. The growth of the TD-LTE market depends on other mobile manufacturers following suit, such as Nokia, Samsung and Apple, which are expected to launch LTE-enabled smartphones in India soon.

iAPPLE IOS 6-FEATURES


Introduction

The next iOS version has never been as big a deal as upgrades to Android or Windows. If it ain't broke, don't fix it, must've been the line of thinking and it's up to you to replace broke with fragmented or catching up, as needed. On the other hand, with the rather rapidly improving hardware, fragmentation is becoming a bit of an issue for Apple to address too.
Anyway, we're now at number 6, along with 5 million (and counting) iPhone 5 users. Now, what follows may seem as a mere prelude to our iPhone 5 review but people only now considering the iPhone 4S may find it quite helpful. By the looks of it, there may be some people considering keeping the iPhone 4S but we're yet to see about that.
Let's focus now on the key additions and improvements to the Apple iOS instead.

Key features

  • Faster and more stable all around
  • Siri available on iPad 3, wider language support with Canadian English, Spanish (Spain/Mexico), Italian, Italian (Switzerland), Korean, Mandarin (Chinese/Taiwan),Cantonese (Hong Kong)
  • Siri now serves sports info, movie and restaurants reviews. It can launch apps and do status updates
  • System-wide Facebook integration: Facebook contacts and events appear in the phonebook and calendar
  • Notification center gets quick Facebook/Twitter update keys
  • New Maps app with TomTom data, turn-by-turn voice navigation and 3D/Flyover view mode
  • Better Safari browser with iCloud tabs, full-screen mode, offline reading and faster performance
  • Passbook e-ticket app handles loyalty coupons, boarding passes, tickets
  • Photo Stream can share photos with other iOS users. Likes and comments are supported
  • Updated Mail app with VIP and Flagged mailboxes
  • Unified FaceTime/iMessages ID. FaceTime works over the cellular network
  • New UI for the App Store, iTunes Store, iBooks Store, Music, Weather apps
  • You can set songs from your music library as alarm tones
  • Improved privacy settings
  • New accessibility options and guided access (single-app mode for kids)
  • Re-organized settings, various new icons
  • Panorama mode in Camera
  • Game Center now supports challenges (achievements)
  • Reject call with SMS
  • Do Not Disturb mode
  • Lost mode
  • Improved keyboards and auto-correction
  • Power toggles moved to top of settings menu (Wi-Fi, Bluetooth, Tethering)
  • Various improvements under the hood

Main disadvantages

  • No offline maps support and maps are not up to scratch currently
  • Variable compatibility across the device range
  • Passbook not on par with Google Wallet, not truly useful
  • An altogether conservative approach to design and layout
  • Notification Center could've offered more functionality
  • No widgets
  • Underused lockscreen
  • Limited themes and personalization options
Apple claims that iOS 6 brings about 200 new features but the noteworthy ones are right there in the bullets above. Depending on where your comfort level is, the major feature can either be the new Maps, the improved Siri or the Facebook integration.
Many people expected to see more from Apple this year but few really had a clear idea what that is. Being "wowed" by Apple has been a legitimate expectation for millions of users out there but those who think their creativity peaked in iOS 4 and the iPhone 4, and has been somewhat flat since, may have a point.
The iOS 6 isn't a dramatic rethink of the design philosophy but brings a reasonable level of change, and improvement, to many important parts of the experience, which will be felt in day to day use.
Follow us as we delve deeper into iOS 6 and find out if Cupertino still has its software chops intact.

21 Things That Will be Obsolete in 2020


1. DESKS
The 21st century does not fit neatly into rows. Neither should your students. Allow the network-based concepts of flow, collaboration, and dynamism help you rearrange your room for authentic 21st century learning.

2. LANGUAGE LABS
Foreign language acquisition is only a smartphone away. Get rid of those clunky desktops and monitors and do something fun with that room.

3. COMPUTERS
Ok, so this is a trick answer. More precisely this one should read: “Our concept of what a computer is.” Because computing is going mobile and over the next decade we’re going to see the full fury of individualized computing via handhelds come to the fore. Can’t wait.

4. HOMEWORK
The 21st century is a 24/7 environment. And the next decade is going to see the traditional temporal boundaries between home and school disappear. And despite whatever Secretary Duncan might say, we don’t need kids to ‘go to school’ more; we need them to ‘learn’ more. And this will be done 24/7 and on the move (see #3).

5. THE ROLE OF STANDARDIZED TESTS IN COLLEGE ADMISSIONS
The AP Exam is on its last legs. The SAT isn’t far behind. Over the next ten years, we will see Digital Portfolios replace test scores as the #1 factor in college admissions.

6. DIFFERENTIATED INSTRUCTION AS A SIGN OF DISTINGUISHED TEACHER 
The 21st century is customizable. In ten years, the teacher who hasn’t yet figured out how to use tech to personalize learning will be the teacher out of a job. Differentiation won’t make you‘distinguished’; it’ll just be a natural part of your work.

7. FEAR OF WIKIPEDIA
Wikipedia is the greatest democratizing force in the world right now. If you are afraid of letting your students peruse it, it’s time you get over yourself.

8. PAPERBACKS
Books were nice. In ten years’ time, all reading will be via digital means. And yes, I know, you like the ‘feel’ of paper. Well, in ten years’ time you’ll hardly tell the difference as ‘paper’ itself becomes digitized.

9. ATTENDANCE OFFICES
Bio scans. ‘Nuff said.

10. LOCKERS
A coat-check, maybe.

11. I.T. DEPARTMENTS
Ok, so this is another trick answer. More subtly put: IT Departments as we currently know them. Cloud computing and a decade’s worth of increased wifi and satellite access will make some of the traditional roles of IT — software, security, and connectivity — a thing of the past. What will IT professionals do with all their free time? Innovate. Look to tech departments to instigate real change in the function of schools over the next twenty years.

12. CENTRALIZED INSTITUTIONS
School buildings are going to become ‘homebases’ of learning, not the institutions where all learning happens. Buildings will get smaller and greener, student and teacher schedules will change to allow less people on campus at any one time, and more teachers and students will be going out into their communities to engage in experiential learning.

13. ORGANIZATION OF EDUCATIONAL SERVICES BY GRADE 
Education over the next ten years will become more individualized, leaving the bulk of grade-based learning in the past. Students will form peer groups by interest and these interest groups will petition for specialized learning. The structure of K-12 will be fundamentally altered.

14. EDUCATION SCHOOLS THAT FAIL TO INTEGRATE TECHNOLOGY
This is actually one that could occur over the next five years. Education Schools have to realize that if they are to remain relevant, they are going to have to demand that 21st century tech integration be modeled by the very professors who are supposed to be preparing our teachers.

15. PAID/OUTSOURCED PROFESSIONAL DEVELOPMENT
No one knows your school as well as you. With the power of a PLN (professional learing networks) in their back pockets, teachers will rise up to replace peripatetic professional development gurus as the source of schoolwide professional development programs. This is already happening.

16. CURRENT CURRICULAR NORMS
There is no reason why every student needs to take however many credits in the same course of study as every other student. The root of curricular change will be the shift in middle schools to a role as foundational content providers and high schools as places for specialized learning.

17. PARENT-TEACHER CONFERENCE NIGHT
Ongoing parent-teacher relations in virtual reality will make parent-teacher conference nights seem quaint. Over the next ten years, parents and teachers will become closer than ever as a result of virtual communication opportunities. And parents will drive schools to become ever more tech integrated.

18. TYPICAL CAFETERIA FOOD
Nutrition information + handhelds + cost comparison = the end of $3.00 bowls of microwaved mac and cheese. At least, I so hope so.

19. OUTSOURCED GRAPHIC DESIGN AND WEB DESIGN
You need a website/brochure/promo/etc.? Well, for goodness sake just let your kids do it. By the end of the decade — in the best of schools — they will be.

20. HIGH SCHOOL ALGEBRA 1
Within the decade, it will either become the norm to teach this course in middle school or we’ll have finally woken up to the fact that there’s no reason to give algebra weight over statistics and I.T. in high school for non-math majors (and they will have all taken it in middle school anyway).

21. PAPER
In ten years’ time, schools will decrease their paper consumption by no less than 90%. And the printing industry and the copier industry and the paper industry itself will either adjust or perish.

அமெரிக்காவில் 24 காரட் தங்கத்தை உருவாக்கும் பாக்டீரியா!


அமெரிக்காவின் மிச்சிகன் மாநிலப் பல்கலைக்கழகத்தைச் சேர்ந்த உயிரியல் துறை விஞ்ஞானிகள் நுண்ணுயிரிகள் குறித்த ஆராய்ச்சியில் ஈடுபட்டனர்.
அப்போது, திரவத் தங்கத்தை உருவாக்கக் கூடிய “கியூப்ரியாவிடஸ் மெடல்லிடியூரன்ஸ்’ என்ற பாக்டீரியாவைக் கண்டுபிடித்தனர். இந்த பாக்டீரியாவில் தங்க குளோரைடு என்ற சேர்மம் நிறைந்துள்ளது. இதையடுத்து, தங்க குளோரைடை இந்த பாக்டீரியாவுக்கு உணவாக உட்செலுத்தினர்.
ஒரு வாரம் கழித்துப் பார்த்தபோது தங்க குளோரைடு, திடத் தங்கமாக (தங்கக் கட்டி) மாறியிருந்தது. அது 24 கேரட் தங்கத்தின் தரத்தில் இருந்தது குறிப்பிடத்தக்கது. இவ்வாறு உருவாக்கப்பட்ட தங்கக்கட்டிகளைக் கொண்டு ஒரு கலைப்பொருளையும் விஞ்ஞானிகள் தயாரித்துள்ளனர். அதை ஆஸ்திரியா நாட்டில் நடைபெற்று வரும் கலைப் போட்டியில் கண்காட்சிக்கு வைத்துள்ளனர்.

Nokia might sell their main office in Finland to get some much needed money


Nokia is headquartered in Espoo, Finland, a city that takes less than 15 minutes to get to via bus from the center of Helsinki. The building they occupy is a stunning architectural achievement made out of steel, glass, and ample quantities of wood. According to Reuters, Nokia is so desperate for cash right now that they’re considering selling the building. It’s estimated that the property is worth between 200 million Euros and 300 million Euros. Does this mean Nokia is planning to leave Finland? No. In fact, Nokia probably isn’t even going to leave the building at all. They’ll likely sell it to someone who will then rent it out to them. This sort of arrangement means Nokia can spend less time worrying about real estate, which is a good thing, but it also means that Nokia can decide to leave the building whenever they want.
How should we really interpret this news? The headlines circulating around the internet right now saying Nokia is going to sell the company’s headquarters don’t exactly increase what little confidence people had left in the company. Betting on Windows Phone back in February 2011 is increasingly looking like a mistake. We’re going to have Nokia’s Q3 financial results in roughly two weeks, and the numbers many analysts and industry experts are going to be paying attention to are how much money Nokia has in the bank, how many Lumia devices were sold, how many Symbian devices were sold, and how much money is Nokia receiving from patent royalties.
Will Nokia be around by the end of next year? Probably, but it’s not going to be in the same shape that it was back in the good old days. There’s still so much we don’t know about Windows Phone 8, including this new rumor that says Microsoft is going to enter the smartphone game. If it’s true … what role, if any, will Nokia have in the future?
