History of PHP and Advanced Development in PHP Programming

The original PHP release was created by Rasmus Lerdorf in June 1995 for his own personal use, to make various common web programming tasks easier and less repetitive and to track the visitors to his online resume.

In 1997, the software transformed from a personal development project into a professional development effort. The name originally stood for “Personal Home Page,” but has since become a recursive acronym, standing for PHP Hypertext Processor.

The goal of this release was to minimize the amount of code required to achieve results, which led to PHP being HTML centric–that is, PHP code was embedded inside HTML.

The second PHP release, known as PHP/F1 2.0 was the first to achieve wide spread popularity, and despite the parsing inconsistencies, it managed to attract a few converts.

The release of PHP 3 was largely driven by Zeev Suraski and Andi Gutmans, who rewrote PHP from the ground up and removed the parsing problems. PHP 3 also made it much easier for others to extend the language. PHP 3 has live up to the design goals of improving the performance of complex applications and modularity of PHP’S code base. Apart from this, it provides end users with a solid infrastructure for lots of different databases, protocols and APIs.

Its successor, PHP 4, contained numerous major changes, including Zend Engine. PHP 4 has introduced multi-threading, which essentially allows particularly lengthy, but non-critical functions to be run independently from the main script process, further streamlining execution.

The engine took over the core of PHP and introduced reference counting, whereby all resources used in scripts (database connections, files, etc) are tracked automatically by the engine, and freed when no longer used to minimize memory usage and ensure there were no memory leaks. In short, Zend engine, take a leading role in improving the performance of PHP scripts.

PHP 5 offers three different types of properties: public, protected and private properties. PHP 5 was released powered by the new Zend Engine II. PHP 5 included new features such as:

Support for object-oriented programming, better support for MYSQL, embedded support for SQlite and integrated SOAP support.
The PHP Data Objects extension, which defines a light weight and consistent interface for accessing databases.
Performance enhancements
Data iterators
Error handling via exceptions

Although not as vast as the jump from PHP 3 to PHP 4, the move from PHP 4 to PHP 5 is still a big one.

Along with hugely improved object orientation, the addition of try/catch error handling, and exceptions, there are two major new extensions: simple XML, a fast and easy-to-learn way to interact with XML documents, and SQLite, a new flat-file database API that eases the burden of deploying simple database solutions.

Software as a Service or SaaS Technology Definition and Advantages

It truly is a more competitive world out there. Businesses know that to be at par with the competition and to grow at a rapid pace, they need to drive innovation within the company and find partner organizations that are cutting edge and would help them dominate the market quickly using practical, simple and cost effective methods.

Rob Purdy, CEO of Carlton Group, a leading edge technology provider, said that in 2011, the IT Channel Planet reported on an IBM survey which said that “mid size businesses are shifting investment priorities more towards innovation and growth and a significant portion of resources are likely to be allocated towards “SaaS” computing. About 70 {bd07e223eb65688a4ec8a013a8a952c18130e3921272d8b06f3376a861906245} of the respondents intended to work with a local channel partner to help meet their technology objectives.”

What exactly is Software as a Service or “SaaS” Technology and why has it become important for businesses?

Information technology research and advisory company Gartner describes SaaS as software thats managed, delivered and owned remotely by providers which could be one or more. The infrastructure and the IT operations that support the applications are also outsourced to the vendor or a different provider. The application that the vendor delivers is an application thats based on one set of data definitions and common code which are then consumed in a one-to-many model by customers at any time. If the software needs to be installed on-premises using the companys infrastructure, that is not SaaS technology.

A Gartner Group estimate put the 2010 sales of this technology at $10 billion and the 2011 sales at about $12.1 billion. By 2015, the IT advisory company estimates that sales figures for SaaS will double the 2010 numbers.

Purdy, citing the Wikipedia definition, said that Saas is “a software delivery model in which software and its associated data are hosted centrally and accessed by users using a web browser over the internet.”

Why are more and more companies choosing Saas? Purdy said the following reasons:

1. He said that many large performance improvement companies have made the decision to migrate their client solutions to SaaS technology because it is much more affordable than traditional software to maintain, faster to implement and in most cases can be fully managed by the end customer.

2. SaaS technology delivers secure, affordable, scalable and easily accessible method to deliver employee recognition performance, loyalty training and even global reward management solutions all on a global scale.

3. SaaS keeps companies competitive. Purdy said, “Companies stand to reap massive rewards by incorporating SaaS solutions into their offerings. Performance improvement companies who do not offer SaaS solutions are less competitive simply because most enterprise level organizations are already using or considering using SaaS technology.

4. Software as a Service or “SaaS” Technology delivers simplicity. “In the words of Martin Henry Fisher, knowledge is a process of piling up facts,” Purdy shared. “Wisdom lies in their simplification. And nothing speaks volumes like simplicity to your customers.”

Qualities Of A Good Computer Repair Service

Since there are plenty of Didsbury computer repair companies around, it can become quite a challenge to find out which one of them is actually a good provider of the service. This is especially true when people start thinking that all computer repair shops are equal anyway. This is definitely not true as there are some shops which are much better than others.

Here are some of the qualities that you should look for to be able to determine whether you have a good computer repair service:

Gives an honest assessment:

When you visit a Didsbury computer repair company, you should inquire first if they are offering free assessments on what repairing your computer would cost. Assessment would often mean trying to boot your computer up, or even opening your system to check what is making it unstable or even unbootable.

By checking the various components and files, the Didsbury computer repair company would then be able to estimate just how much you would have to spend and wait for your computer to become fixed. The great thing with an assessment is that if there are minor issues such as lose cables and the like, then the computer repair teams can reconnect and fix them for free.

Explains the roles of the components that need fixing:

Another quality of a good Didsbury computer repair company is that they would be able to explain to you why they are replacing or fixing a part of your computer. By being able to explain, you would be able to check and ask around if they are actually offering a proper fix for your busted computer.

Of course, there may be some people who are not as tech savvy as the others, and think that they do not care about the technical things that the team might say. However, people who would actually take the time to listen would be able to use these tips to ask more knowledgeable people around as to whether the fix that they are offering is a legitimate way of fixing the computer issues.

Service with a smile:

Tech people are often stereotyped as being apathetic or uncaring to people who do not really understand technology. That is why you would know that you have entered a good Didsbury computer repair service if you find that the employees are more than willing to help out and assist both the tech-savvy people as well as the beginners.

Increase Multimedia Keyboard Experience

It’s been a long time since manufacturers started including extra keys on their keyboards. These keys were supposed to increase usability and offer shortcuts for many typical tasks. But how many computer users were actually using these extra keys?

In point of fact, not many. Each manufacturer provided their own sets of keys, and unique keyboard drivers that people were reluctant to install, and bulky buggy software that was supposed to handle extra key presses.

Keyboard Maniac adds a new dimension to the ability to control applications on your computer using convenient keyboard shortcuts and on any keyboard from any manufacturer. Put your music at your fingertips by controlling your favorite multimedia player with dedicated multimedia keys. Use your wireless keyboard as a powerful, fully functional remote control for watching movies. Save time by scripting your day-to-day tasks with pre-recorded keyboard macros.

Assign a single, easy-to-remember keyboard shortcut that does all the complex actions with a single press by recording global or application-specific macros. Macros are sets of key presses and mouse clicks that are invoked with the push of a single keyboard shortcut.
Winamp, Windows Media Player and PowerDVD are three popular media players. They all have controls to play, pause and rewind music or videos. Can your multimedia keyboard control all of them? Keyboard Maniac allows the same keys and shortcuts on your keyboard to work in different applications, allowing you to assign a single easy to remember key to control the music in various media players.

Keyboard Maniac is not limited to just the media players either. You can also assign convenient keys for the actions you perform most often in the office.

Server Virtualization Challenges

Server virtualization is a business strategy that is here to stay and that offers many considerable organizational benefits. You can consolidate application workloads that are running on underutilized servers which can result in reductions in hardware costs, energy and infrastructure costs, and space requirements. Additionally, server virtualization can also increase the availability and reliability of applications, improve disaster recovery efforts, and streamline data backup.

Realizing these server virtualization benefits does require some effort. These fantastic benefits are not automatic, despite all the hype surrounding server virtualization. They require a skillset that may be new to some organizations, and thus planning needs to be taken seriously and with forethought. Server virtualization, in fact, may not be a good fit for your organization and so when possible, a consultant that has experience in virtual server deployment and a strong virtualization methodology should be used.

Server virtualization works best for applications that utilize less than half of a servers capacity or resources. Larger, transactional database applications are typically not a good fit for server virtualization.

Given the fact that most servers are grossly underutilized, there is a huge waste of IT resources likely at any organization. Virtualization uses a hypervisor, which is software that transparently allocates server resources and manages resource conflict. This, in turn, allows multiple applications to share the same physical server increasing the utilization of the machine. While simple in theory, there are challenges that come with server virtualization.

Workload capacity and performance planning

When you suddenly increase the utilization of an underutilized server, you automatically create the need to better manage that servers performance. Depending on the application being run on the server, this increased utilization could cause problems.

Operational processes and procedures

Like the first challenge, the sudden increase in server utilization may require your organization to redefine internal processes for monitoring performance, and possibly the tools used to monitor server diagnostics.

System architecture and design

Youll need to determine (before your server virtualization effort) how virtualization will affect overall budget, system component selection, how much CPU, storage capacity, and network bandwidth youll need so that your effort runs smoothly.

Storage allocation and management

Youll need to consider application transaction rates and capacity usage so that you allocate the appropriate amount of storage space. If not, youll run the risk of exceeding available capacity and constraining your application performance.

Security

Security vulnerabilities are amplified in a virtual server environment, so be sure to address security patching and access control.

While these challenges are not tiny, they are very manageable provided theyre addressed prior to server virtualization. Consult with a server virtualization expert to help you get it right.

How To Disassemble A Computer System

Cleaning the dust on your computer is very important part of computer maintenance. Problems like computer heating occur due to dust problem. To get the computer cleaning job done you can consult a computer repair company or try it on your own. But for this you need to disassemble a computer system. Not only for cleaning, if you want to slot in a new hardware component then too you need to disassemble your computer. Do you know how to do this? If not, this is the article for you. Here we will discuss how to disassemble a computer system.

Disassembling a computer can be a painful and daunting task but it is really not that difficult. Following are some useful tips which you should remember while performing the task. The first thing you should do is, cut off the power. This means you need to disconnect the computer from all power sources. Start with the power cord and then the other cables like monitor cable, mouse and keyboard wires and other devices like the sound box, etc.

Once you disconnect all the cables, you need to open the computer case. There are some PCs slides off the side. You need to remove some screws before the cover can come off. There are also other cases that open in different ways. So, it is suggested to check your specific computer case. In the market you will find cases, those are designed in such way so that the user can open the case easily.

After removing the computer case, you will have a look at all the components in the computer. You will find the motherboard, SMPS, hard disk, memory modules and other components. In addition, you will also find Video card, sound card, CPU, etc. You should learn about the components inside the case to maintain your computer.

You also need to remove adapter cards. For instance if there is a PCI based sound card, you will need to take note of the screw at the top of the bracket. To disconnect the card, first you need to remove that screw. Next you need to disconnect disk drives. Hard disks usually have screws at the side. The job these screws are to secure the hard drive in the PC’s drive bays. Be careful while unscrewing those, otherwise you precious hard disk may drop on the motherboard.

These are some useful tips for disassembling your computer. At the time of opening up your computer, you should remember these things. This will help you to avoid any potential problems at the time cleaning your computer or installing any new hardware component.
