Venice Backstage. How does Venice work? from Insula spa on Vimeo.

• API: Application program interface
• CRUD: Create Read Update Delete
• DOM: Document Object Model
• HTML: Hypertext Markup Language
• HTTP: Hypertext Transfer Protocol
• JSON: JavaScript Object Notation
• MVC: Model-View-Controller
• OOP: Object-oriented programming
• ORM: Object-Relational Mapping
• REST: Representational State Transfer
• RPC: Remote procedure call
• SQL: Structured Query Language
• URL: Uniform Resource Locator
• WSDL: Web Services Description Language
• XML: Extensible Markup Language

Now first check what the delete method will do:

Delete method deletes the row with a primary key matching the id argument, using a SQL DELETE statement, and returns the number of rows deleted. Active Record objects are not instantiated, so the object‘s callbacks are not executed, including any :dependent association options or Observer methods.

You can delete multiple rows at once by passing an Array of ids.

It is much faster than the destroy method, skipping callbacks might bypass business logic in your application that makes the function to work fast.

example:
Delete a single row
user.delete(1)

Delete multiple rows
user.delete([2,3,4])

Destroy method:
The destroy method makes the SQL call to the database and destroys the row in the table that contains it. It does still allow you to manipulate the object in the application as long as it’s still in scope (i.e) the callbacks and
filters are allowed even after destroying the object.

example :
Destroy a single object
User.destroy(1)

Destroy multiple objects
users= [1,2,3]
User.destroy(users)

Rails has a philosophy includes the following:

1) DRY: (Don't Repeat Yourself)
In rails, it suggests that writing the same code again and again for several times is not a good process. Instead of writing the same code again and again, we can partition that particular part of code in to a seperate block or function or something else and can reuse it whenever and wherever we need it in the current application.

2) Convention over Configuration:
In rails, almost the process of development will be done using the conventions instead of a * configuration settings for our application. If we follow the conventions (guidelines of rails) in development process, everything will be taken care by rails about our application.

3) REST: (Representational State Transfer)
In rails, REST will have two main features. They are:
a) Using resource identifiers like URLs to represent the resources of our application.
b) Transferring the representations of the state of a particular resource among system components.
REST will be useful for routing in our applications for the specification of path for a particular resource. And REST consists of HTTP verbose for our application like:
a) POST b) GET c) PUT d) DELETE.

MVC architecture:
The MVC architecture in Rails application has:

1) Model:
Model will consist of the data about our applications and is used to manipulate the content of models (tables). It will contain the validations, rules and set of guidelines to manipulate our models.

2) View:
View will consist of the templates of html pages, which will be visible for public/user. It will purely concentrate on the representation of data our application.

3) Controller:
Controller is the thing which will have the control over both Model and View. The Controller will receive the requests from the user (from views) and will send that request to respective model to have the information, and will pass the data to the users in form of a view.

The representation of MVC Architecture will be as follows:

View————————–Controller———————–Model
(User interface)————–(Controllers)——————(Databases)

Immutable objects :
1)Immutable objects are objects whose state never changes after creation.

2)Immutable objects are thread-safe(A piece of code is called as thread-safe ,if it functions correctly during simultaneous execution by multiple threads).

Freezing Objects:
1:The freeze method in class Object prevents you from changing an object, effectively turning an object into a constant.
2:After we freeze an object, an attempt to modify the freezed object, results in TypeError.
3: freeze operates on an object reference, not on a variable.
4:This means that any operation resulting in a new object.

Example:
str = 'A simple string. '
str.freeze
begin
str << 'An attempt to modify.'
rescue => err
puts "#{err.class} #{err}"
end

# The output is – TypeError can't modify frozen string

Evernote:
Evernote's universal note app on Android is not as elegant, fast, or intuitive as Evernote on iPhone. But with the latest update, the app has gotten a lot more usable. There's a home screen widget for quickly searching out notes or recording new text, image, or audio notes. You can send any text, image, or audio on your phone to Evernote through the "Share" menu. And with offline caching and speed improvements, Evernote offers an impressive, seamless thoughts-into-notes experience.

TripIt:
TripIt saves you from the print-outs, email searching, and airport panic sessions common to modern-day travel. Sign up for TripIt, forward your travel itineraries along (or have TripIt automatically import them from Gmail), and then you've got a whole master travel plan on your phone—check-in links, flight information, weather and traffic stats for your destination, and so on. It's an essential for frequent fliers, hotel guests, and train travelers.

Facebook for Android:
Until this past month, it was a shame how diminished the Facebook client looked in the shadow of its successful iPhone counterpart. But now Facebook's Android presence is capable, good-looking, and even offers a few of its own unique perks, like a pull-up notifications shade and a front-page scroll of recent photos from friends.

Google Voice:
Android's tight integration with Google Voice, the service that puts your voicemail, SMS, and phone management in the cloud, is one of its key selling points. After many revisions, Google's Voice app now makes calling or SMS messaging with a Voice number nearly indistinguishable from a standard call, and the voicemail transcriptions and playback are just another nice bonus of the Google halo.

Twitter for Android:
Honestly, we could have gone one of a few ways with this recommendation, but Twitter seems like the best app for the average Twitter user. Other apps, like Seesmic and Twidroyd, offer all kinds of nitpick options, like choosing between old-school "RT" and the official retweet methods and supporting multiple accounts. But if you like clean looks, smooth transitions, and just an easy way to update your status, the official app is the way to go.

Barcode Scanner:
Until the Market updates with Google's plans to provide over-the-air, instant browser-to-phone app installation, Android enthusiasts have taken to scanning quirky barcodes, or QR codes, to quickly install an application from a blog or print magazine recommendation. To grab those QRs, you need Barcode Scanner. It also offers some basic Google search functionality, but there are better shopping apps, one covered in this list in particular.

• Checks code for error
• Checks code for syntax 
• Show linkages between various modules
• Detects code duplication

Doxygen can be configured to render nice inheritance graphs with graphviz. It can help you in three ways:

• It can generate an on-line documentation browser (in HTML) and/or an off-line reference manual (in ) from a set of documented source files. There is also support for generating output in RTF (MS-Word), PostScript, hyperlinked PDF, compressed HTML, and Unix man pages. The documentation is extracted directly from the sources, which makes it much easier to keep the documentation consistent with the source code.
• You can configure doxygen to extract the code structure from undocumented source files. This is very useful to quickly find your way in large source distributions. You can also visualize the relations between the various elements by means of include dependency graphs, inheritance diagrams, and collaboration diagrams, which are all generated automatically.

phpCallGraph. is a tool to generate static call graphs for PHP source code. Such a graph visualizes the call dependencies among methods or functions of an application. Arrows represent calls from one method to another method. Classes are drawn as rectangles containing the respective methods. The graphs can be leveraged to gain a better understanding of large PHP applications or even to debunk design flaws in them.

PMDs duplicate code detection for PHP code. 

Yasca — Yet Another Source Code Analyzer, a plugin-based framework for scanning arbitrary file types, with plugins for scanning PHP and other file types. It integrates with other scanners, including FindBugs, JLint, PMD, and Pixy.

DMS Software Reengineering Toolkit — Supports custom analysis of PHP  and many other languages. Also COTS tools for clone analysis, dead code analysis, and style checking.

Fortify — Helps developers identify software security vulnerabilities in PHP as well as configuration files.

Sikkim (Lepcha: Mayel Lyang; Limbu: Yuksom, one of the fortified place;^[1] Standard Tibetan: , bras ljongs; Denzong;^[2] Demojongs; Nepali: सिक्किम (help·info), i.e. the Goodly Region, or Shikim, Shikimpati or Sikkim of the English and Indians…^[3]) is a landlocked Indian state nestled in the Himalayas. It is the least populous state in India and the second-smallest state after Goa.^[4] This thumb-shaped state borders Nepal in the west, the Tibet Autonomous Region of the People's Republic of China to the north and the east and Bhutan in the southeast. The Indian state of West Bengal borders Sikkim to its south.^[5] Despite its small area of 7,096 km² (2,740 sq mi), Sikkim is geographically diverse due to its location in the Himalayas. The climate ranges from subtropical to high alpine. Kangchenjunga, the world's third-highest peak, is located on the border of Sikkim with Nepal.^[6] Sikkim is a popular tourist destination owing to its culture, scenic beauty and biodiversity.

Legend has it that the Buddhist saint Guru Rinpoche visited Sikkim in the 9th century, introduced Buddhism and foretold the era of the monarchy. Indeed, the Namgyal dynasty was established in 1642. Over the next 150 years, the kingdom witnessed frequent raids and territorial losses to Nepalese invaders. It allied itself with the British rulers of India but was soon annexed by them. Later, Sikkim became a British protectorate and merged with India following a referendum in 1975.

Sikkim has 11 official languages: Nepali (lingua franca), Bhutia, Lepcha (since 1977), Limbu (since 1981), Newari, Rai, Gurung, Mangar, Sherpa, Tamang (since 1995) and Sunwar (since 1996).^[7] English is taught at schools and used in government documents. It is the only state in India with an ethnic Nepalese majority. The predominant religions are Hinduism and Vajrayana Buddhism. Gangtok is the capital and the largest town. Sikkim has a booming economy dependent on agriculture and tourism, and has the only open border between India and China.

But i was able to install namazu on LINUX and was also able to install namazu as a PHP extension on LINUX. While stumbling though site searching for installing namazu with PHP5 i got this link which describes how one can install namazu on LINUX and its PHP extension also.

I will keep on searching how to get namazu as a PHP extension, meanwhile you can use this link to get namazu working on LINUX.
