Other Decks in Technology


  1. You Tube by Deespark: YouTube is a video-sharing website, created

    by three former PayPal employees in February 2005, on which users can upload, view and share videos. The company is based in San Bruno, California, and uses Adobe Flash Video and HTML5 technology to display a wide variety of user-generated video content, including movie clips, TV clips, and music videos, as well as amateur content such as video blogging and short original videos. Most of the content on YouTube has been uploaded by individuals, although media corporations including CBS, the BBC, VEVO, Hulu, and other organizations offer some of their material via the site, as part of the YouTube partnership program.Unregistered users can watch videos, while registered users can upload an unlimited number of videos.
  2. Videos considered to contain potentially offensive content are available only

    to registered users at least 18 years old. In November 2006, YouTube, LLC was bought by Google for US$1.65 billion, and now operates as a subsidiary of Google. Features Video technology • Playback • Uploading • Quality and codecs • 3D videos • Content accessibility • Record or webcam Video Embedding : Face book, myspace, blogs, twitter, etc. Public or Private : User can able select their uploading videos publicity as Public or private.
  3. Android by Suseendra: Android was originally a Linux based operation

    system developed by Android Inc. According to wikipedia, it was purchased by Google in 2005 in a move to gain an edge in the mobile area. Android operating system is a open source, unlike apple secretive code, Google has choose to give away most of the code that Powers Android. Because the code is free to developers and manufactures, it is very attractive to device manufactures who prefer to spend their resources on manufacturing high quality device instead of reinventing the wheel by creating a proprietary operating system. Another great advantage of the Android operating system is the large and growing community of developers who are constantly create new applications for use an Android devices. These applications can be free or paid at the Android Market. The Android market has over 3,00,000 apps, quickly catching up to Apple’s store.
  4. jQuery by Venkatesh : jQuery is a cross-browser JavaScript library

    designed to simplify the client-side scripting of HTML. It was released in January 2006 at BarCamp NYC by John Resig. Used by over 55% of the 10,000 most visited websites, jQuery is the most popular JavaScript library in use today. jQuery is free, open source software, dual-licensed under the MIT License or the GNU General Public License, Version 2. jQuery's syntax is designed to make it easier to navigate a document, select DOM elements, create animations, handle events, and develop Ajax applications. jQuery also provides capabilities for developers to create plug-ins on top of the JavaScript library. This enables developers to create abstractions for low-level interaction and animation, advanced effects and high-level, theme-able widgets. The modular approach to the jQuery library allows the creation of powerful dynamic web pages and web applications.
  5. Microsoft and Nokia have announced plans to bundle jQuery on

    their platforms, Microsoft is adopting it initially within Visual Studio for use within Microsoft's ASP.NET AJAX framework and ASP.NET MVC Framework while Nokia has integrated it into their Web Run-Time widget development platform. Features: jQuery includes the following features: • DOM element selections • DOM traversal and modification (including support for CSS 1-3) • DOM manipulation based on CSS selectors. • Events, Effects and animations, Ajax, Extensibility through plug-ins • Utilities - such as user agent information, feature detection • Compatibility methods that are natively available in modern browsers but need fallbacks for older ones - For example the inArray() and each() functions. • Cross-browser support
  6. Digital Signature by Gokul: A Digital signature (standard electronic signature)

    takes the concept of traditional paper-based signing and turn it into an electronic "fingerprint.” This "fingerprint,” or coded message, is unique to both the document and the signer and binds both of them together. The digital signature ensures the authenticity of the signer. Any changes made to the document after it is signed invalidate the signature, thereby protecting against signature forgery and information tampering. Digital signatures help organizations sustain signer authenticity, accountability, data integrity and non-repudiation of electronic documents and forms. An electronic signature is defined as an electronic sound (e.g., audio files of a person's voice), symbol (e.g., a graphic representation of a person in JPEG file), or process (e.g., a procedure that conveys assent), attached to or logically associated with a record, and executed or adopted by a person with the intent to sign the record.
  7. Due to this reality, an electronic signature that does not

    incorporate additional measures of security (similar to a digital signature, described above) are considered an insecure way of signing documentation. A digital signature, often referred to as advanced or standard electronic signature, is a sub group within electronic signatures which provide the highest form of signature and content integrity as well as universal acceptance. The digital signature is based on Public Key Infrastructure (PKI) and is a result of a cryptographic operation that guarantees signer authenticity, data integrity and non- repudiation of signed documents. The digital signature cannot be copied, tampered or altered. In addition, because they are based on standard PKI technology, digital signatures made within one application (e.g. Microsoft® Word, Adobe® PDF) can be validated by others using the same applications.
  8. On the other hand, an electronic signature is a proprietary

    format (there is no standard for electronic signatures) that is an electronic data, such as a digitized image of a handwritten signature, a symbol, voiceprint, etc., that identifies the author(s) of an electronic message. An electronic signature is vulnerable to copying and tampering, making forgery easy. In many cases, they are not legally binding and will require proprietary software to validate the e-signature. An electronic signature is easy to implement, since something as simple as a typed name can serve as one. Consequently, e-signatures are very problematic with regards to maintaining integrity and security, as there is nothing to prevent one individual from typing another individual's name.
  9. Celebrate the Kennedy Space Center’s 50th birthday with Street View

    by Arumugam: Google Maps with Street View lets you explore places around the world through 360-degree street-level imagery. You can explore world landmarks, view natural wonders, navigate a trip, go inside restaurants and small businesses - and now even visit the Amazon!
