Symfony web application framework

Symfony is a web application framework written in PHP which follows the model-view-controller (MVC) paradigm. Released under the MIT license, Symfony is free software. Symfony aims to speed up the creation and maintenance of web applications and to replace repetitive coding tasks. It requires a few prerequisites for installation: Unix, Linux, Mac OS or Microsoft Windows with a web server and PHP 5 installed. It is currently compatible with the following object-relational mappings: Propel and Doctrine.

Symfony has low performance overheads when dealing with an environment that supports a PHP accelerator. Symfony is aimed at building robust applications in an enterprise context, and aims to give developers full control over the configuration: from the directory structure to the foreign libraries, almost everything can be customized. To match enterprise development guidelines, Symfony is bundled with additional tools to help developers test, debug and document projects.

Symfony makes use of many common and well understood design patterns, such as Model-View-Controller. Symfony was heavily inspired by other Web Application Frameworks such as Ruby On Rails, Django and Spring.

Symfony – Model view controller software architecture:

Model–view–controller (MVC) is a software architecture, currently considered an architectural pattern used in software engineering. The pattern isolates "domain logic" (the application logic for the user) from the user interface, permitting independent development, testing and maintenance of each.

Though MVC comes in different flavors, control flow is generally as follows:

• The user interacts with the user interface in some way (for example, by pressing a mouse button).
• The controller handles the input event from the user interface, often via a registered handler or callback, and converts the event into an appropriate user action, understandable for the model.
• The controller notifies the model of the user action, possibly resulting in a change in the model's state.
• A view queries the model in order to generate an appropriate user interface (for example the view lists the shopping cart's contents). The view gets its own data from the model. In some implementations, the controller may issue a general instruction to the view to render itself. In others, the view is automatically notified by the model of changes in state (Observer) that require a screen update.
• The user interface waits for further user interactions, which restarts the control flow cycle.

Some implementations such as the W3C XForms also use the concept of a dependency graph to automate the updating of views when data in the model changes.

The goal of MVC is, by decoupling models and views, to reduce the complexity in architectural design and to increase flexibility and maintainability of code. MVC has also been used to simplify the design of Autonomic and Self-Managed systems. The model manages the behavior and data of the application domain, responds to requests for information about its state, and responds to instructions to change state. In event-driven systems, the model notifies observers when the information changes so that they can react.

The view renders the model into a form suitable for interaction, typically a user interface element. Multiple views can exist for a single model for different purposes. A viewport typically has a one to one correspondence with a display surface and knows how to render to it. The controller receives user input and initiates a response by making calls on model objects. A controller accepts input from the user and instructs the model and viewport to perform actions based on that input.

New Google Analytics SDK for Android - Version 1.3

New and improved version of the Google Analytics SDK for Android, This release is jam-packed with lots of good fixes, improved methods, and most importantly, better campaign tracking!  Read on for all the juicy details.

General Campaign Tracking
This new feature is probably the most exciting one for this release.  The SDK now supports the ability to set campaign referral information at any time, instead of at installation time.  This gives advertisers the ability to now track ads which lead people to user their app. To learn more about this feature and how to use it, check out the new campaign tracking section in our documentation.

Anonymizing IP Addresses
To provide more privacy to your users, we added a new setAnonymizeIp method in the GoogleAnalyticsTracker class. This removes the last octet of the IP address prior to storage and makes the tracking more anonymous 

Configuring The Sample Rate
If you are getting a large volume of traffic, you can set the tracking sample rate to only send a portion of data to Google Analytics. Once configured, the tracker will decide based on visitor ID whether to send hits.

Deprecations
We are deprecating the start and stop methods in favor of the startNewSession and stopSession. The existing methods will continue to be in the library, so your applications will still work when you upgrade, but we highlight recommend you move to these new methods.

Bug Fixes

In this release we were also able to fix three bugs:

1. We’ve fixed a few issues with how the SDK accesses SQLite. As a result you will see less warnings and the SDK now uses less memory!

2. We’ve fixed a bug that might occur if you’re using custom variables.

3. The tracker no longer uses the application context passed to the SDK when starting up.  This should avoid memory leaks caused by holding Activity Contexts beyond the life of the Activity.

We hope you’ll find this latest version of the Google Analytics SDK for Android to be a big improvement over previous versions.  We also hope you realize we’re committed to making Google Analytics a first class provider of mobile app analytics as well as web analytics.

There’s plenty more coming for the Google Analytics SDKs for both Android and iOS.  Stay tuned.

Keyword stuffing - considered to be black hat seo technique

Keywords stuffing are considered to be black hat seo technique. Keyword stuffing occurs when a web page is loaded with keywords in the web page meta tags or in content. The replication of words in meta tags may explain why many search engines no longer use these tags. Keyword stuffing had been used in the past to gain maximum search engine ranking and visibility for particular keywords. This method is totally outdated and adds no value to rankings today. In exacting, Google no longer gives good rankings to pages employing this technique.

We can do Hiding text from the visitor in many different ways. Text colored to blend with the background, CSS "Z" positioning to place text "at the back" an image — and therefore out of view of the visitor — and CSS absolute positioning to have the text positioned far from the page center are all common techniques. By 2005, many hidden text techniques were easily detected by major search engines. "No script" tags are another way to place hidden content within a page. While they are a valid optimization method for displaying an alternative representation of scripted content, they may be abused, since search engines may index content that is hidden to most visitors.

Occasionally inserted text includes words that are frequently searched (for example, "car") even if these terms have little connection to the page content, to attract traffic to advert-driven pages. In the past, keyword stuffing is considered to be a white hat or black hat technique, depending on the context of the technique, and the opinion of the person judging. While a lot of keyword stuffing is used to help spamdexing, which is of little benefit to the user, keyword stuffing in certain conditions, intended to bias the results in a misleading way. If the keyword has a pejorative or neutral connotation is dependent on whether the practice is used to contaminate the results with pages of little relevance, or to drive traffic to a page of relevance that would otherwise have been downplayed because of the inability of search engine to interpret and understand related ideas. This is no longer the case. Search engines now employ techniques thematic keywords related to the interpretation of the intent of the content of a page.
