Managing Bandwidth

Are you a net surfer?

Do you want to reduce the bandwidth consumption?

Do you want to improve the network performance?

How to reduce the load on web server and makes web pages load faster?

Answer to above questions is Squid, which is web caching software independent of platform. Squid is a proxy server and web cache daemon. It has a wide variety of uses, from speeding up a web server by caching repeated requests; to caching web, DNS and other computer network lookups for a group of people sharing network resources; to aiding security by filtering traffic. So now the hosting companies have started providing Squid hosting.

Features of Squid:

• It acts as a firewall and proxies your internal web traffic.
• It ensures that only authorized users can surf the Internet, behaves like a parental lock and prevent users from browsing inappropriate websites
• It filters sensitive information from web requests and enhances your privacy.
• Beneficial for companies, libraries, organizations, colleges and schools where IPod is a charm and given to the students of class VI onwards.
• Squid has extensive access controls and makes a great server accelerator. It runs on most available operating systems, including Windows and is licensed under the GNU GPL..

Compiling and Installing Squid:

Compiling Squid is relatively straightforward. If you’ve installed more than a few open source packages, you’re probably already familiar with the procedure. You first use a program called. /configure to probe your system and then a program called makes to do the actual compiling. To compile squid you basically need an ANSI C compiler. Except ANSI C compiler you’ll also need Perl and awk. Awk is a standard program on all UNIX systems, so you shouldn’t need to worry about it. Perl is quite common, but it may not be installed on your system by default. You may need the gzip program to uncompress the source distribution file.

After compiling, now you need to install the programs into their permanent directories. This might require super user privileges, to put files in the installation directories. f you enable Squid’s ICMP measurement features with the enable-icmp option, you must install the pinger program. The pinger program must be installed with super user privileges because only root is allowed to send and receive ICMP messages. The following command installs pinger with the appropriate permissions:

# make install-pinger

Running Squid: Squid normally runs as a daemon process. If you are new to Squid, however, I recommend running Squid in the foreground from a terminal window until you are confident that it is working properly. Following that, you can run Squid as a daemon, in the background. You can send signals to the running Squid process to execute various tasks, such as halting and reconfiguring Squid, and rotating the log files. Although you can use the kill command to send signals, it is easier to use the squid -k commands. –k is basically an administrative function which has the following functions: reconfigure, rotate, shutdown, interrupt, kill, debug, check, or parse. Before running Squid for the first time, and whenever you add a new cache_dir, you must initialize the cache directories. The command is simply:

% squid –z

Using Squid’s sophisticated access controls: As we all know that access controls are the most important part of any configuration file. We can use them to grant access to the authorized users and to stop unauthorized access. You can use them to restrict, prevent access to, to control request rewriting, to route requests through a hierarchy and to support different qualities of service.

Basically, access controls are built on two different components. You can define a number of access control list elements. These elements refer to specific aspects of client requests, such as IP addresses, URL hostnames and request methods. After defining the necessary elements, you combine them into a number of access list rules. The rules apply to particular services or operations within Squid.

As your access control configuration becomes longer, it also becomes more complicated. I strongly encourage you to test your access controls before turning them loose on a production server. Of course, the first thing you should do is make sure that Squid can correctly parse your configuration file. Use the -k parse feature for this:

% squid -k parse

Tuning disk storage for optimal performance: Squid has a number of different storage schemes. The schemes have different properties and techniques for organizing and accessing cache data on the disk. Most of them use the file system interface system calls. Squid has five different storage schemes: ufs, aufs, diskd, coss, and null. The first three use the same directory layout, and they are thus interchangeable. coss is an attempt to implement a new file system specifically optimized for Squid. Null is a minimal implementation of the API: it doesn’t actually read or write data to/from the disk.

As long as the total disk usage is below cache_swap_low, Squid doesn’t remove cached objects. As the cache size increases, Squid becomes more aggressive about removing objects. Under steady-state conditions, you should find that disk usage stays relatively close to the cache_swap_low value.

Configuring your operating system for HTTP interception: As we all know that the operating system of Squid is configured to accept the foreign packets and deliver them to the Squid process. First of all to make HTTP interception work, we will need to configure three separate components: a network device, Squid’s operating system, and Squid itself. The obvious benefit of interception caching is that all HTTP requests leaving your network automatically go through Squid. You don’t need to worry about configuring any browsers or that users might disable their proxy settings. Interception caching puts you, the network administrator, in control of the HTTP traffic. You can change, add, or remove Squid caches from service without significantly interrupting your users’ web surfing.

Forwarding Requests to other web caches: May be there can be any reason to find that you want Squid to forward its cache misses to another cache or HTTP proxy. This is necessary, for example, if you are using Squid inside a large corporate network that has one or more firewalls protecting you from the outside world. And if your caching service is actually a cluster of Squid caches, you probably want them to cooperate with each other to minimize duplication of cached responses. You can also use Squid as a content router routing web traffic in different directions based on some aspect of the request. Or, perhaps you’d like to participate in an informal collection of caches to further improve response time and reduce wide-area network traffic.

Using redirectors to rewrite user requests: The most important fact about Squid is that it has the ability to alter requested URLs. If used as an external process then Squid can be configured to pass every incoming URL through a helper process that returns either a new URL, or a blank line to indicate no change. It allows the administrator to control the locations to which his users go.The redirector feature allows you to implement a number of interesting things with Squid. Many sites use them for access controls, removing advertisements, local mirrors, or even working around browser bugs. A redirector is really just a program that reads a URI and other information from its input and writes a new URI on its output. Perl and Python are popular languages for redirectors, although some authors use compiled languages such as C for better performance. We can use redirectors to rewrite user requests.

Monitoring Squid with the cache manager and SNMP: One important fact that Squid writes various messages to cache.log as it runs. Most of these are abnormal events of one sort or another. But for some reasons, Squid isn’t always smart enough to differentiate serious problems from those that can be safely ignored. Without many problems also cache.log is a good place to start when investigating a Squid problem. The cache manager and SNMP interfaces allow you to query Squid for a variety of data. The cache manager, which has its own shortcomings, probably provides the most information in current versions of Squid. Squid supports SNMP as well. Unfortunately, the data available through SNMP is only a subset of the cache-manager information. So with the help of cache manager and SNMP we can easily monitor Squid.

Using Squid to accelerate and protect HTTP servers: Server acceleration is generally used as a technique to improve the performance of slow, or heavily loaded, backend servers. It works well because origin servers tend to have a relatively small hot set.

Managing bandwidth consumption with Delay Pools: Bandwidth control in squid entails two steps. One is to create an ACL (Access Control List) and the other to create a delay pool. In the Squid configuration menu, go to the Access control option. Here you’ll notice that some default ACLs are already made. Create an access control of your own. Delay pools provide a means to restrict bandwidth usage of clients. With delay pools, clients can be restricted at the individual level, or in groups. ACLs are used to apply bandwidth limits to users. For creating Delay pools, go to the main Squid configuration interface and select the Delay pool option.

Steps for installing movable type
How to personalize movable type?
Features of movable type:
Requirements for Movable Type:

Movable Type is a weblog publishing system which is a low-cost, distributed software solution which helps thousands of web site developers to organize and automate the web content management process. Movable Type has several notable features, such as the ability to host multiple weblogs and standalone content pages, manage files, user roles, templates, tags, categories, and trackback links.

It supports static and dynamic page generation.

It also supports LDAP (Lightweight Directory Access Protocol) which is an application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. Movable type will run on just about any server, the only requirements are a database and the ability to run CGI scripts.
There are currently two separate distributions of Movable Type, the commercial version (still free for individual users) and the open source version.

Deciding which one to use depends what you need and what you’re willing to pay for. Movable Type is written in Perl, and supports storage of the weblog’s content and associated data within MySQL. Most of the cheap hosting companies are using movable type for those websites that are basically used for blogging.

Steps taken while installing movable type:

– Download the latest release from internet.

– Download desired version, or copy url if using SSH to install.

– Two paths to do this based up on what level of server access is available:

1. FTP – download locally, un-compress, then upload parts via FTP .

• After downloading release to your local machine, double-click the archive to un-compress.
• Upload (or move) the static directory via FTP to the web root of the website.
• Upload the application directory without the static directory via FTP to the cgi-bin directory.
• Rename the application directory from “MT-5.0-en” to “mt”.

2. SSH – upload via SSH, un-compress on the server, move directories.

• Login to the server and cd to the cgi-bin directory.
• Copy release to the server.
• Unzip the release archive.
• Change the name of the directory from the versioned name. Move the static directory to the web root.

How to personalize movable type?

Movable Type is an extensible platform that allows developers to not only create simple template tags and text filters, but in fact design entire applications. In that way Movable Type is much like an Application Server, by abstracting the developer away from a lot of the mundane tasks of web application development: like writing SQL, providing database caching, and defining frequently used user interface components like dialogs, tables, and more.

Hosting with movable type is quite simple and easy.
Movable Type is itself an application that sits upon this platform, using its own APIs, callbacks, and interfaces to define the application you use every day. In this way, when looking for help with the API there is no better example than Movable Type itself. For example if you want to create new screen inside the application then it has to be in three simple steps:

1. Create a template for rendering the contents of the page,
2. Define a mode handler which populates the template’s context with data,
3. Register a method to route requests to the mode handler.

In order to take movable type behaving the way you want it’s important to understand how it works. Movable Type has two main components, the backend administration interface where you can manage your blogs, post new entries, moderate comments and more, and the front-facing public website.

Features of movable type:

• Movable Type is an all-in-one solution. Create websites, add blogs, manage content, and build a social community – all in one package.
• Movable Type is scalable. As your site grows and becomes more successful, the platform scales to accommodate your fluctuating traffic needs.
• Movable Type is proven. For more than eight years, Movable Type has been on the forefront of blogging innovation, and powers some of the largest and most influential websites and blogs on the web.
• Movable Type is supported. We offer support for businesses, optional support for bloggers, and premium support for enterprise and high-traffic bloggers.
• Powerful Dashboard. Generate new websites or blogs from a single screen. View a summary of website and blog activity in one glance.
• WYSIWYG Editor. Makes it easy to create great-looking pages and posts.
• Universal Template Set. Create and deploy blogs or standalone websites.
• User Dashboard. Manage websites or blogs you are authorized to manage.
• Revision History. See revisions for entries, pages, and templates.
• Custom Fields. Available for Website, Blog, Comment, Template, Asset, Entry, Page, Category, Folder, and User.
• Asset Manager. Easily manage files and media assets from a single screen.

UI Frameworks for building mobile web apps
Challenges in building Android web app
HTML5 storage APIs
Location based Mobile Mapping

It is now within the reach with new web technologies (HTML5 are combined with CSS3 and JavaScript) to develop web applications for Android and other mobile devices.

Android was built from the ground-up to enable developers to create compelling mobile applications that take full advantage of all a handset has to offer Android is built on the open Linux Kernel. Furthermore, it utilizes a custom virtual machine that was designed to optimize memory and hardware resources in a mobile environment.

Android is open source; it can be liberally extended to incorporate new cutting edge technologies as they emerge. The platform will continue to evolve as the developer community works together to build innovative mobile applications. Android provides access to a wide range of useful libraries and tools that can be used to build rich applications. Android includes a full set of tools that have been built from the ground up alongside the platform providing developers with high productivity and deep insight into their applications.

Why to have web app on the Android platform?

Applications are usually developed in the Java language using the Android Software Development Kit, but other development tools are available, including a Native Development Kit for applications or extensions in C or C++, Google App Inventor, a visual environment for novice programmers and various cross platform mobile web applications frameworks.

There are essentially two ways to deliver an application on Android: as a client-side application (developed using the Android SDK and installed on user devices as an .apk) or as a web application (developed using web standards and accessed through a web browser—there’s nothing to install on user devices). A decision to develop a web application for Android can exclude consideration for screen support, because it’s already easy to make your web pages look good on all types of screens powered by Android.

UI frameworks for building mobile web apps

Frameworks and libraries help the web development process or a web developer to focus on creating rather than creating the stuff.

The frameworks for building mobile web apps are:

– DHTMLX Touch – HTML5 JavaScript Framework for Mobile: This is an HTML5 framework which uses JavaScript for mobile and touch devices. This HTML5-based JavaScript library lets you build cross-platform web applications for mobile and touch-screen devices.

– Behat – BDD Framework for PHP: Unlike any other php testing framework that tests applications inside out. Behat is testing applications outside in. It means, that Behat works only with your application’s input/output.

– Initializr – HTML5 Templates Generator: An HTML5 templates generator that helps you get started with your HTML5 project. It does that by generating a clean customizable template with just what your project needs.

– PUF PHP Utility Framework: A comprehensive collection of useful and popular PHP utility functions created to save time for developers that regularly use those functions when building web applications.

– Sprout Core – An HTML5 Application Framework: An HTML5 application framework which lets you simply creates desktop-level applications for modern web browsers.

– MOBI- Open SourceHTML5 Based Language: An open-source HTML5-based language designed to speed up your building of mobile web applications.

– GURY- HTML5 canvas Utility Library: Gury is a JavaScript library designed to help in the creation of HTML5 and Canvas applications. You can create a canvas tag, resize and style it, add renderable objects, animate those objects, and place it anywhere on the page in a single chained expression.

– JQuery Form Framework: jFormer is a form framework written on top of jQuery that allows you to quickly generate beautiful, standards compliant forms.

– Galleria-JavaScript Image Gallery Framework: Galleria is a JavaScript image gallery framework, built upon jQuery, which simplifies the process of creating professional image galleries for websites and web/mobile apps.

Challenges in building Android web app:

The success of Android as an open platform in the past couple of years is made evident by the huge volume and diversity of devices offered by manufacturers. In this highly competitive market, device manufacturers strive to differentiate themselves via innovation over the existing platform. Some of the challenges are:

1. Mobile Hardware and Software Diversity: The diversity that now exists between software and hardware platforms for mobile devices is undeniable. Choosing a specific platform will limit the developer to the capabilities and features of this platform. Even within one platform, there could be several different versions that can make applications behave differently from one device to another.

2. Mobile OS Frequent Updates and Releases: A challenge that may arise during mobile development is the ability of the application developed to be altered to match updates. Mobile platforms are very frequently updated and new versions come out quite often. Developed applications must be easily upgraded to fit the requirements and adapt to the changes of newer and better software versions.

3. Power, Processing and Storage Management: Another significant challenge that comes with mobile without the need to look at the phone. When a message is received, the system informs the user through speech synthesis that he/she has received a new message from certain contact. The system then asks the user if he/she would like to hear the message. The system will then start the speech recognition and wait for the user to respond. Go to Top

Building a Mobile HTML Entry Form:

Forms are upgraded in HTML5 to make your life easier. They don’t necessarily do anything that I’d consider mind-blowing or even web-changing, but they make a lot of our current hacks easier. To start we’re only going to track the first two holes. Each of these holes is Par 4’s, which we expect each golfer to be able to make. We’ll also ask for an email address.

HTML5 Storage APIs:

HTML5 uses three kinds of storages:

1. Web storage: For basic local storage with key/value pairs. The most basic implementation of storing data locally on the user’s machine is with the web storage API. This API uses key/value pairs to allow developers to store basic information and variables that can be accessed by the web application.
2. Offline storage: Uses a manifest to cache entire files for offline used. Sometimes simply storing a bit of data on the user’s machine won’t be enough. In many cases, the entire application may have to work offline, not just store some data. For that use case, HTML5 includes the ability to cache files and assets on the user’s machine that the browser can then access without an Internet connection.
3. Web database: For relational database storage. The last type of storage that HTML5 introduced is the one that is most in flux currently. Originally there was a Web SQL specification that is no longer maintained. Now most of the energy has moved into working on an Indexed Database API and it looks like this will be the way to store information in a relational database going forward.

Constructing a Multipage App:

To show different “pages” or “screens”, use a View Stack-style control. A View Stack is similar to the common UI element Tab Panel Each View Stack page is loaded at start, so if you’re loading a lot of data, you’ll need to implement Lazy loading. You can also implement page-like behavior with states, but state changes primarily involve moving, hiding, and showing elements on screen, similar to DOM manipulation via JavaScript.

Synchronizing with the Cloud:

Companies no longer need to maintain large and expensive “parks” of servers 24 hours a day when there is another less expensive alternative: hiring such services through fully managed cloud hosting providers. Through virtualization, applications that previously ran on custom environments may be duplicated or “having created image” to run in the cloud server provider. Cloud computing, where mobile devices balance powerful servers, needs an operating system that makes the most of the system architects and developers can do on a small client computer. Android is the operating system.

Competing with Native Apps :

Native apps can be easily found in the relevant app stores and are normally developed individually or on a mobile platform. Mobile functionality can be split into two dimensions: the user experience, and the way it integrates into the device’s ecosystem. For Android or iOS, this includes features like widgets and push notifications. Native apps excel in both dimensions, with HTML5 approaching from a distance.

Exploring Interactivity :

With the use of android apps the interacting part of the customers with the android apps has increased. Android is a software platform that involves comprehensive Android application development. Android is comprised of operating system, middleware and other key applications. Android application development truly measures up to the expectation of funky modern urban citizen in a sense that its flexibility is enough to provide users wider scope of applications and services.

Location Based Services and Mobile Mapping :

The mobile web has really come of age in the last couple of years, thanks in large part to innovations ushered in by the iPhone and the iPod Touch, and more recently Android devices. With the help of android services we can easily find any location to where we want to go as most of the mobile apps are built on android platform. The unique combination of these location-aware devices and “mobile browser with touch” technologies has opened a wide range of possibilities for mobile applications.

Native Bridging with PhoneGap:

PhoneGap is a native bridging framework in the purest sense. It is an enabler for accessing the native capabilities of a multitude of devices using web technologies as much as possible. You can write web applications with hooks into the native capabilities of the device in your JavaScript code. Structure your application well and you should be able to support progressive enhancement using those additional native capabilities. Once you have done this, you should very easily be able to make your application available through both the device application stores and online at a url of your choosing.

The Future of Mobile Computing:

Android’s open nature makes it possible for hardware developers to use it for whatever new devices they can imagine. Its SDK makes it easy for application developers to create the applications users want and need. Both factors make Android a strong contender for the shape of the future of mobile computing.

Debugging Android Web Apps :

The Android SDK provides most of the tools that you need to debug your applications. You need a JDWP-compliant debugger if you want to be able to do things such as step through code, view variable values, and pause execution of an application. If you are using Eclipse, a JDWP-compliant debugger is already included and there is no setup required. If you are using another IDE, you can use the debugger that comes with it and attach the debugger to a special port so it can communicate with the application VMs on your devices.

Hosting with XHTML,CSS abd Graphics

Limitations of XHTML
Sample of XHTML
About DTDs
What is the role of CSS

Web hosting service is a type of internet hosting service that allows individuals and organizations to make website accessible via World Wide Web. The hosting companies provide a particular space on the server provided by the web hosting company. That space is provided according to what the user wants and is that space suitable for the user. Websites can be hosted in many different platforms. So if hosting of the website is done with XHTML, CSS and web graphics then how it will be working. So let’s go in brief about XHTML, CSS and web graphics.

XHTML is the stricter and cleaner form of HTML and is very much identical to HTML 4.01. XHTML is responsible for the structure of the web pages whereas presentation is handled by CSS (Cascading Style Sheets). The first version of it is known as XHTML 1.0. It used the existing three document types of HTML and reformulated them as applications of XML. XHTML is the recommendation of W3C (Worldwide Web Consortium), an organization to make and maintain standards for the Internet and its associated technologies.

Some limitations about XHTML:

• XHTML documents must have only one root element
• XHTML elements must be properly nested
• XHTML elements must always be closed
• XHTML elements must all be in lowercase
• XHTML tags attribute names must be in lower case
• XHTML tags attribute values must be quoted
• XHTML tags attribute minimization is forbidden

Websites are designed multi-column CSS layouts with optimized graphic files, the process of website development includes:

• Getting Web Hosting, Domain name and FTP Access: Get the best business hosting plan which helps you in providing the user best hosting.  Business hosting plan provides following :

The FTP (File Transfer Protocol, File Transfer Protocol) is one of the oldest within the Internet. It is a service that users use frequently (driver downloads, music, documents, etc..), But this is only part of the service, since it is also possible to implement in our machine, FTP server for other users can connect to our computer and pick up / leave information in a particular area.

•Create a simple (X)HTML page, how to add links and images: An XHTML document has a very simple structure. It has a header, which contains information about the document, and a body, which contains the main content of the document. To markup this structure, you need three tags – <html>, <head>, and <body>.

For eg:

<?xml version=”1.0″ encoding=”UTF-8″?>
<!DOCTYPE htmlPUBLIC “-//W3C//DTD XHTML 1.0 Strict//EN””DTD/xhtml1-strict.dtd”>
<html xmlns=”http://www.w3.org/1999/xhtml&#8221; xml:lang=”en” lang=”en”>
<head>
<title> Strict DTD XHTML Example </title>
</head>
<body>
<p>
Please Choose a Day:
<br /><br />
<select name=”day”>
<option selected=”selected”>Monday</option>
<option>Tuesday</option>
<option>Wednesday</option>
</select>
</p>
</body>
</html>

• Web standards –

Facts about XHTML:

1. XHTML documents start with an <html> tag – there is no such thing as an <xhtml> tag.
2. It is required that you declare the XHTML namespace inside the opening <html> tag.
3. This XHTML example covered the use of XHTML transitional – for XHTML strict or frameset, use the appropriate DOCTYPE Declaration.
4. Remember that declaring a DOCTYPE with a valid identifier at the top of an XHTML page puts most browers in standards mode- so remember not to use old browser hacks, and non-standard tags. (Otherwise, use just use regular HTML)
5. For some browsers, including Microsoft Internet Explorer 6, if you start an XHTML page with the XML declaration, the browser goes into quirks mode, an unfortunate bug. The workaround is to delete the optional declaration and declare the the encoding using a meta tag.
6. The DOCTYPE declaration has to be in all uppercase characters, just like in the XHTML example code.

What are DTD’s?

XML defines the DTD [document type definition] to avail variable contents to display them. XML conversion services are useful for newspapers, magazines, journals, technical and various documents, graphics and other republishing services. The source file is converted and validated with best validating software; every individual tag will be validated by automated method to make sure the highest quality standard is achieved. The purpose of a DTD (Document Type Definition) is to define the legal building blocks of an XML document. A DTD defines the document structure with a list of legal elements and attributes. Three types of DTD’s are there:

a. Strict:

You should use the strict DTD when your XHTML pages will be marked up cleanly, free of presentational clutter. You use the strict DTD together with cascading style sheets, because it doesn’t allow attributes like “bgcolor” to be set for the <body> tag, etc.

b. Transitional

The transitional DTD should be used when you need to take advantage of the presentational features that are available through HTML. You should also use the transitional DTD when you want to support older browsers that don’t have built-in support for cascading style sheets.

c. Frameset

You should use the frameset DTD when your XHTML page will contain frames.

• Cascading Style Sheets – CSS stands for Cascading Style Sheets. Styles define how to display HTML elements. Styles were added to HTML 4.0 to solve a problem. External Style Sheets can save a lot of work. External Style Sheets are stored in CSS files. CSS defines HOW HTML elements are to be displayed. CSS allows us to create visual settings for our internet documents. CSS is not a tool to enrich the business or logical layers of websites. The main and only purpose of CSS is to enrich and give a better control to visual aspects such as page layout, page color, text and decorations and the like.

CSS also allows us to define different display of the same content in different situations. For example, using CSS it can be configured to display content differently in a browser or printed document. CSS also allows us to customize the way one reader or a group of readers will see our site according to various characteristics that we can define in advance.

For example if you want to change the background color of a page then CSS is as follows:

<html>
<head>
<style type=”text/css”>
body
{
background-color:#b0c4de;
}
</style>
</head>
<body>
<h1>My CSS web page!</h1>
<p>HELLO! Welcome to webhostingcheap.net</p>
</body>
</html>

• Web graphics: Graphics are visual elements often used to point readers and viewers to particular information. They are also used to supplement text in an effort to aid readers in their understanding of a particular concept or make the concept more clear or interesting.

Graphics can be functional or artistic. The latter can be a recorded version, such as a photograph, or an interpretation by a scientist to highlight essential features, or an artist, in which case the distinction with imaginary graphics may become blurred.  Web graphic design has been professed as the easiest and modern method for online connectedness, exploring other arenas of typography for designs. It uses visual arts, creative and cognitive skills, etc. for creating that quest to grouping. In primary events equal fluid publicity, competent illustration designs activity a better portrayal in determining the open soul for the kind.
