Drupal is content management system software that is much-beloved by a large and thriving developer community. The ever-evolving magnum opus of developer Dries Buytaert, the system, its modules, users and developers value flexibility, simplicity, utility, modularity, extensibility and maintainability in the code. The theory here seems to be that the core files are made light and feature-less – a blank canvas on which to create.

This philosophy obviously isn’t for everyone. The code is clean and light (only a few M but that’s because you will need to install/tweak many (20-30) plugins before you have the site of your dreams.

Standout Features

* Modules – thousands of them for utility, content, third-party integration, admin, content, media, e-commerce, and on and on.
* Intense levels of personalization – considered to be the “core of Drupal.”
* Fully indexed and searchable content.
* Role-based permissions – not so different from our other highly ranked systems, but vital nonetheless.

Built-in Applications:

Main criticisms of Drupal include that the countless modules are also its biggest drawback: a site in this system is nothing without many installed modules and conversely maintenance on 20+ modules is a nightmare. Also, this system is not object-oriented, which a lot of potential users find off-putting.

Some say Drupal is the best they’ve ever used – some say it is the worst. This just seems to be more proof that a content management system software is only as good as its user – meaning know what you need before choosing any CMS.

Back to Drupal, as stated before, this system is lacking in built-in features yet can’t really be compared to any other system nor directly penalized in our ratings for same. The Drupal stalwarts all contend that handling large amounts of modules and working around the bugs is completely do-able and worth the time.

User forums also reveal this system is weak when dealing with image modules – there are three that overlap but no one does it all on its own. So beware to photo-heavy sites.

Management:

This CMS does offer a lot in the way of built-in management – almost everything on our list. Analysis, tracking and statistics are built-in and you will definitely need these if you are running an online business of any kind. Having a site is almost pointless if you don’t pay attention to how it’s performing traffic-wise and make adjustments based on that research.

The web-based administration is a great plus here – you can administer your Drupal site from a web browser anywhere in the world and doesn’t require any additional software or installation for such.

Performance:

Caching is a must with this system since you will be running plenty of modules in addition to your core files, especially if your site has a lot of visitors as well. You can configure this option from the Administrator>Site Configuration>Performance path. This reduces queries to the server and will help a busy site stay up and running fast for its users.

The system also performs load balancing between multiple servers as another way to keep the site running smoothly and quickly. This is a built-in feature.

Commerce:

All commerce options in Drupal are available as plugins. This system doesn’t have a point-of-sale function.

Ease of Use:

Server page language and friendly URLs are the only built-ins here. Everything else on our list (with the exception of UI levels) can be added on for free.

Support:

Drupal content management system software offers the full complement of support, with smoke tests available – you guessed it – as a plugin. The forums and documentation aren’t perfect, but they are active and if you do have a nailbiter of a problem, you should be able to find someone or something to help you out.

Summary:

Drupal is an amazing assemblage of Open Source development, working from scratch and creating something totally unique. It’s most certainly made for developers, though. It's not content management system software for the faint-of-heart.

If you are planning a community site or a high traffic site, Drupal might not be the best choice. For less developer-heavy features, try another of our highly ranked products such as Wordpress.org or Joomla!

eZ Publish is one of the world’s leading Open Source Enterprise CMS and development architecture. Some users might consider this complex framework to be complicated, but generally agree that eZ Publish has one feature that stands above the rest: the ability to create different content classes in the administration interface. If you want to create your own custom site on a solid framework, this CMS could be for you.

Standout Features

* Web publishing
* Intranets
* E-commerce capability
* Commercial support and documentation
* Wiki capability

Built-in Applications:

With eZ Publish content management system, if it’s not included, it’s a free add-on when it comes to built-in applications. Extensions, as they are called in this system, are many and easily downloadable from the developer’s site.

This system lets you easily publish content such as files, photos and articles using the Website Toolbar – directly from your web browser. When you log in you will see the toolbar which will give you the option to publish, move, replace or even translate your content.

There is no HTML coding required when adding content – the rich text editor is WYSIWYG and offers the formatting functions you would see in a word processing app. You can also publish your content right from your word processing program using OpenOffice. This makes it possible for you to create content independent of internet access then upload the document using a client or the front-end of your site.

We can see why this style of interface might seem foreign to users of Drupal, Joomla! or the like – it looks different and doesn’t behave like a typical “dashboard”. But if what you want in a CMS is flexibility and expandability, eZ Publish really does offer it all as far as the many elements we’ve reviewed here.

Management:

All the management elements in our side-by-side comparison are covered by eZ Publish – from advertising management to the workflow engine.

One of the things we loved most from this category was the upload capabilities – you can batch upload and also the system detects the type of content and creates web pages accordingly. You can upload many photos at once and store them in a gallery – the system automatically scales, formats and resizes photos according to their content type and destination. This is a huge time-saving feature.

The administration interface is comprehensive, offering content management and editing, site management, configuration, customization and development.

The workflow engine is a really amazing mechanism. It has a built-in collaboration system that allows an administrator to pre-define a sequence of actions to be performed in a specific order after an object is published.

The content model is also very unique – the content engine lets administrators create content definitions on graphical interfaces.
Content cross publishing and versioning and modification tracking are a couple of the other super-powerful and versatile elements that are sure to be useful to large companies with diverse offerings.

Commerce:

If you’re in search of a content management system with e-commerce capability, this one offers plenty of options to make that possible. Shopping cart and wish list functions are built-in. Also built-in is the option to plugin your preferred payment service, shipping calculator and tax calculator. These are all available as extensions to your eZ Publish installation.

Ease of Use:

This CMS takes a while to learn and become familiar with, but after spending a week or so, we felt it was indeed eZ to publish and use. The rich text editor is WYSIWYG, which means you don’t need to know any code to create text content.

The access system is multi-level and role-based. The admin can give a user or an entire group (writers, designers, video production, etc.) of users access to just the specific functions they need to do their jobs.

Support:

eZ Publish content management system software offers the full complement of support, online and off. If you can’t figure out the system on your own, try the online documentation and forums. The developers also offer commercial manuals, support and training if you’re from a large company looking to implement this system company-wide.

Smoke tests are fairly standard with this level of code and we agree that it’s essential to not breaking your site – it’s a secure area within the CMS where you can test new code, plugins, updates, etc, and check to make sure it’ not going to break anything on implementation.

The built-in prototyping allows for default settings to be made for various content types – then when you need to reuse the certain type of content, the settings have already been created.

Images are automatically resized when you upload them into the system and the system also creates friendly (short, comprehensible) URLs which helps with search engine optimization as well as being easy to find and read by humans.

Summary:

If you are looking for a quick fix to a content problem and you are not so knowledgeable about web development (PHP, server configurations, etc.) you should avoid eZ Publish content management system software and go for something lighter such as WordPress.org or Movable Type, both of which are considered a little more “plug-n-play”.

If you have a large company with a professional Web developer, eZ Publish CMS could be the best decision you ever make! It’s difficult to judge these amazing systems by just looking at a collection of check marks, but it can give you a great idea of the standard features available and a starting point from which to consider your own specific needs.

One of the key values at Facebook is to move fast. For the past six years, we have been able to accomplish a lot thanks to rapid pace of development that PHP offers. As a programming language, PHP is simple. Simple to learn, simple to write, simple to read, and simple to debug. We are able to get new engineers ramped up at Facebook a lot faster with PHP than with other languages, which allows us to innovate faster.

Today I'm excited to share the project a small team of amazing people and I have been working on for the past two years; HipHop for PHP. With HipHop we've reduced the CPU usage on our Web servers on average by about fifty percent, depending on the page. Less CPU means fewer servers, which means less overhead. This project has had a tremendous impact on Facebook. We feel the Web at large can benefit from HipHop, so we are releasing it as open source this evening in hope that it brings a new focus toward scaling large complex websites with PHP. While HipHop has shown us incredible results, it's certainly not complete and you should be comfortable with beta software before trying it out.

HipHop for PHP isn't technically a compiler itself. Rather it is a source code transformer. HipHop programmatically transforms your PHP source code into highly optimized C++ and then uses g++ to compile it. HipHop executes the source code in a semantically equivalent manner and sacrifices some rarely used features — such as eval() — in exchange for improved performance. HipHop includes a code transformer, a reimplementation of PHP's runtime system, and a rewrite of many common PHP Extensions to take advantage of these performance optimizations.

Scaling PHP as a Scripting Language
PHP's roots are those of a scripting language, like Perl, Python, and Ruby, all of which have major benefits in terms of programmer productivity and the ability to iterate quickly on products. This is compared to more traditional compiled languages like C++ and interpreted languages like Java. On the other hand, scripting languages are known to generally be less efficient when it comes to CPU and memory usage. Because of this, it's been challenging to scale Facebook to over 400 billion PHP-based page views every month.

One common way to address these inefficiencies is to rewrite the more complex parts of your PHP application directly in C++ as PHP Extensions. This largely transforms PHP into a glue language between your front end HTML and application logic in C++. From a technical perspective this works well, but drastically reduces the number of engineers who are able to work on your entire application. Learning C++ is only the first step to writing PHP Extensions, the second is understanding the Zend APIs. Given that our engineering team is relatively small — there are over one million users to every engineer — we can't afford to make parts of our codebase less accessible than others.

Scaling Facebook is particularly challenging because almost every page view is a logged-in user with a customized experience. When you view your home page we need to look up all of your friends, query their most relevant updates (from a custom service we've built called Multifeed), filter the results based on your privacy settings, then fill out the stories with comments, photos, likes, and all the rich data that people love about Facebook. All of this in just under a second. HipHop allows us to write the logic that does the final page assembly in PHP and iterate it quickly while relying on custom back-end services in C++, Erlang, Java, or Python to service the News Feed, search, Chat, and other core parts of the site.

Since 2007 we've thought about a few different ways to solve these problems and have even tried implementing a few of them. The common suggestion is to just rewrite Facebook in another language, but given the complexity and speed of development of the site this would take some time to accomplish. We've rewritten aspects of the Zend Engine — PHP's internals — and contributed those patches back into the PHP project, but ultimately haven't seen the sort of performance increases that are needed. HipHop's benefits are nearly transparent to our development speed.

Hacking Up HipHop
One night at a Hackathon a few years ago (see Prime Time Hack), I started my first piece of code transforming PHP into C++. The languages are fairly similar syntactically and C++ drastically outperforms PHP when it comes to both CPU and memory usage. Even PHP itself is written in C. We knew that it was impossible to successfully rewrite an entire codebase of this size by hand, but wondered what would happen if we built a system to do it programmatically.

Finding new ways to improve PHP performance isn't a new concept. At run time the Zend Engine turns your PHP source into opcodes which are then run through the Zend Virtual Machine. Open source projects such as APC and eAccelerator cache this output and are used by the majority of PHP powered websites. There's also Zend Server, a commercial product which makes PHP faster via opcode optimization and caching. Instead, we were thinking about transforming PHP source directly into C++ which can then be turned into native machine code. Even compiling PHP isn't a new idea, open source projects like Roadsend and phc compile PHP to C, Quercus compiles PHP to Java, and Phalanger compiles PHP to .Net.

Needless to say, it took longer than that single Hackathon. Eight months later, I had enough code to demonstrate it is indeed possible to run faster with compiled code. We quickly added Iain Proctor and Minghui Yang to the team to speed up the pace of the project. We spent the next ten months finishing up all the coding and the following six months testing on production servers. We are proud to say that at this point, we are serving over 90% of our Web traffic using HipHop, all only six months after deployment.

How HipHop Works
The main challenge of the project was bridging the gap between PHP and C++. PHP is a scripting language with dynamic, weak typing. C++ is a compiled language with static typing. While PHP allows you to write magical dynamic features, most PHP is relatively straightforward. It's more likely that you see if (...) {...} else {..} than it is to see function foo($x) { include $x; }. This is where we gain in performance. Whenever possible our generated code uses static binding for functions and variables. We also use type inference to pick the most specific type possible for our variables and thus save memory.

The transformation process includes three main steps:

Static analysis where we collect information on who declares what and dependencies,
Type inference where we choose the most specific type between C++ scalars, String, Array, classes, Object, and Variant, and
Code generation which for the most part is a direct correspondence from PHP statements and expressions to C++ statements and expressions.

We have also developed HPHPi, which is an experimental interpreter designed for development. When using HPHPi you don't need to compile your PHP source code before running it. It's helped us catch bugs in HipHop itself and provides engineers a way to use HipHop without changing how they write PHP.

Overall HipHop allows us to keep the best aspects of PHP while taking advantage of the performance benefits of C++. In total, we have written over 300,000 lines of code and more than 5,000 unit tests. All of this will be released this evening on GitHub under the open source PHP license.

Learn More this Evening
This evening we're hosting a small group of developers to dive deeper into HipHop for PHP and will be streaming this tech talk live. Check back here around 7:30pm Pacific time if you'd like to watch.

As I'm sure there will be plenty of questions, starting this evening take a look at the HipHop wiki or join the HipHop developer mailing list. You'll also find us at FOSDEM, SCALE, PHP UK, ConFoo, TEK X, and OSCON over the next few months talking about HipHop for PHP. We're very excited to evolve HipHop into a thriving open source project along with all of you.

If you're building a SaaS (Software as a Service) startup you're in great company. Most software entrepreneurs today are taking this approach -- including me. Below are some simple insights that I've learned in the process of being in the trenches with my own startup.

Insights On SaaS Startups

1. You are financing your customers. Most SaaS businesses are subscription-based (there’s usually no big upfront payment). As a result, sales and marketing costs are front-loaded, but revenue comes in over time. This can create cash-flow issues. The higher your sales growth, the larger the gap in cash-flows. This is why fast-growing SaaS companies often raise large amounts of capital. My marketing software company is an example.

2. You’ve got operating costs. In the shrinkwrapped software business, you shipped disks/CDs/DVDs (or made the software available to download). There were very few infrastructure costs. To deliver software as a service, you need to invest in infrastructure — including people to keep things running. Services like Amazon’s EC2 help a lot (in terms of having flexible scalability), but it still doesn’t obviate the need to have people that will manage the infrastructure. For a startup, the people cost to manage the IT stuff can be significant (since the team is very small). So, even though hardware and infrastrucutre are cheap, managing it can take a significant percentage of the startup’s time.

3. It Pays To Know Your Funnel: One of the central drivers in the business will be understanding the shape of your marketing/sales funnel. What channels are driving prospects into your funnel? What’s the conversion rate of random web visitors to trial? Trial to purchase? Purchase to delighted customer? As a SaaS startup grows, a lot of leverage can be found by understanding the shape of the funnel and removing the “leaks” (i.e. where are you losing business)? For example, if a lot of people are signing up for the trial, but very few convert to paying customers, you should dig into what the early usage pattern is. Are people logging on at all? If so, where are they getting stuck? Remove the friction that is keeping customers from getting value and you’ll unlock some revenue. Do this at all stages of the funnel (focusing on the easy stuff first).

4. Install Knobs and Dials In The Business: One of the great things about the SaaS business is you have lots of aspects of the business you can tweak (examples include pricing, packaging/features and trial duration). It’s often tempting to tweak and optimize the business too early. In the early days, the key is to install the knobs and dials and build gauges to measure as much as you can (without driving yourself crazy). Get really good at efficient experimentation (i.e. I can turn this knob and see it have this effect). As with most experiments, don’t change too much at the same time (even though you think several different things will all have positive effects). The reason is simple: If you change more than one thing, you won’t really know what really happened. Unless you have lots of data points, simple tests are usually better.

5. Value the Visibility: One of the big benefits of SaaS businesses is that they often operate on a shorter feedback cycle. You’re dealing in days/weeks/months not in quarters/years/lifetimes. What this means is that when bad things start to happen (as many experienced during the start of the current economic downturn), you’ll notice it sooner. This is a very good thing. It’s like driving a fast car. Good breaks allow you to go faster (because you know you can slow down if conditions require). But, great visibility helps too — you can better see what’s happening around you, and what’s coming. The net result is that the risk of going faster is mitigated.

Running a SaaS startup is a lot of fun. There are so many more things under your control than the traditional shrink-wrapped business. Use this to your advantage. Keep your feedback cycles short, maniacally track the data and invest in continual (but cheap) experimentation. In the long term, these things will give you a huge advantage.

What have you learned while building your SaaS startup?

Drupal Content Management System . It's easy to install, and immensely adaptable
In simple language we can say that Drupal is a content management system that makes use of modules to allow site administrators to organize and display content,customize appearance and manage routine tasks, such as registration for websites requiring user names and passwords.

Within minutes of installing this PHP framework, you can have a feature-rich, database-driven site with no knowledge of programming required. And you can add off-the-shelf contributed modules to add even more features to your site.

Drupal is an open source content management platform licensed under the GPL. Equipped with a powerful blend of features, Drupal can support a variety of websites ranging from personal blogs, corporate brochures and large community-driven websites.

While it is not the purpose of this manual to fully educate you on database, web server or operating systems basics specific to your site, this will hopefully introduce you to getting a Drupal based website installed and configured for your needs. For a more technical sounding definition;

Drupal is a web-based content management system. Text and pointers to other kinds of content are stored in a database, dynamically retrieved and composed, and presented to a user in response to a request sent via a web-browser.

Drupal was originally written by Dries Buytaert, who still heads the Drupal project. Buytaert transliterated the Dutch word 'druppel,' which means 'droplet' to create the name 'Drupal,' in order to make an indirect reference to the community aspects of the project through the Dutch word 'dorp,' meaning 'village.' He opened the source code for community work in 2001.

Drupal is a free software package that allows an individual or a community of users to easily publish, manage and organize a wide variety of content on a website. Tens of thousands of people and organizations are using Drupal to power scores of different web sites, including

1) Community web portals
2) Discussion sites
3) Corporate web sites
4) Intranet applications
5) Personal web sites or blogs
6) Aficionado sites
7) E-commerce applications
8) Resource directories
9) Social Networking sites

The built-in functionality, combined with dozens of freely available add-on modules, will enable features such as:

1) Electronic commerce
2) Blogs
3) Collaborative authoring environments
4) Forums
5) Peer-to-peer networking
6) Newsletters
7) Podcasting
8) Picture galleries
9) File uploads and downloads

and much more.

Drupal is open-source software distributed under the GPL ("GNU General Public License") and is maintained and developed by a community of thousands of users and developers.

Joomla Whats This

Want to know more ok lets start introduction about joomla

Joomla is an award-winning content management system (CMS), which enables you to build Web sites and powerful online applications. Joomla is an open source solution that is freely available to everyone.

A content management system is software that keeps track of every piece of content on your Web site, much like your local public library keeps track of books and stores them. Content can be simple text, photos, music, video, documents, or just about anything you can think of. A major advantage of using a CMS is that it requires almost no technical skill or knowledge to manage. Since the CMS manages all your content, you don't have to.

Joomla is used all over the world to power Web sites of all shapes and sizes. For example:

1) Corporate Web sites or portals
2) Corporate intranets and extranets
3) Online magazines, newspapers, and publications
4) E-commerce and online reservations
5) Government applications
6) Small business Web sites
7) Non-profit and organizational Web sites
8) Community-based portals
9) School and church Web sites
10) Personal or family homepages

Many companies and organizations have requirements that go beyond what is available in the basic Joomla package. In those cases, Joomla's powerful application framework makes it easy for developers to create sophisticated add-ons that extend the power of Joomla into virtually unlimited directions.

The core Joomla framework enables developers to quickly and easily build:

1) Inventory control systems
2) Data reporting tools
3) Application bridges
4) Custom product catalogs
5) Integrated e-commerce systems
6) Complex business directories
7) Reservation systems
8) Communication tools

Hai Hi you are facing memory size problem ?

PHP Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate … bytes) in …

The error normally occurs when PHP tries to process a big database records or when importing or exporting. To solve the error, there are two resolutions. One is to change and increase the memory limit of the particular PHP script by adding or including an additional line at the top of the script:

ini_set('memory_limit','16M');

Another way is to modify php ini file

To change the memory allocation limit permanently for all PHP scripts running on the server, modify the PHP.INI configuration file of the server. Search for memory_limit after opening the file in an editor. If the memory_limit doesn’t exist, add the following line. If it’s there, modify the value of the memory_limit:

memory_limit = 16M

The 12M sets the limit to 12 megabytes (12582912 bytes). Change to the value you desirable.

An alternative way is to modify your PHP scripts that generate the error for more efficiency and better data handling.

If you want to save memory which script than you have to unset variables and methods ok.

For more details contact Us.
