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.

Virtual Private Server

Virtual private server is nothing but a marketing term used by Internet Hosting Services which refers to a virtual machine for the use of an individual customer availing the service. Even software running on the same computer as same as the individual customer computer, it absolutely work as a separate computer and for the need of the customer. It also has the privacy of the separate physical computer and can run just like a server computer if configured. The term VDS is less used for the same process compared to VPS, each of these can run their own operating system and can be independently rebooted, which helps the user a lot in configuring any process and using it. Partitioning of a single server is done so that it can be showed as multiple has been in practice since a long time, especially both on mainframe computer and mid range computers. It has become more popular with the development occurring day by day in case of virtualization of software and technologies for micro computers.

It bridges the gap between dedicated hosting services and shared web hosting services by giving independence of the VPS services in software terms. It cost less compared to physical dedicated servers. It runs at its own operating system and is capable of running any software on other operating systems some doesnt run in virtualized ones. There are two types of hosting, the first one is Unmanaged and other is unmetered. In the case of unmanaged one the customer is left to monitor and administer their own server and in the case of unmetered one, unlimited amount of data transfer is allowed on a fixed bandwidth line. Unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s.

Here the customer can use 3.33~ TB on 10 Mbit/s, 33~ TB on 100 Mbit/s and 333~ TB on a 1000 Mbit/s line. A VPS is also referred as cloud server it has two attributes which are- additional hardware resources can be added at runtime (CPU, RAM), and Server can be moved to other hardware while the server is running (automatically according to load in some cases). As an intermediary service between shared web hosting and dedicated server hosting, the actual hardware server is divided into several isolated environments. Each environment, or space of the hardware, has its own server software, mail server, and independent software instances and services. VPS hosting offers an extremely affordable hosting solution for business owners.

NTP Server Systems The Network Time Protocol

Posted August 1, 2018 By www-2016nf-com

NTP Server Operation

A NTP server can operate in three modes: unicast; anycast and multicast. In unicast and anycast modes, the client transmits a NTP request message to the server. The server responds with a NTP time message that the client uses for time synchronisation. In multicast mode, NTP time messages are broadcast at periodic specified intervals.

NTP Reference Clocks

Primary NTP servers can synchronise with a number of external reference time sources. The GPS (Global Positioning System) is often used to provide an accurate timing reference. There is also a number of national time and frequency radio broadcasts available. The WWVB radio time broadcast is transmitted from Colorado and covers most of the US. The DCF-77 radio time signal is broadcast from Frankfurt, Germany, and covers much of central and Western Europe. The MSF radio time signal is broadcast from Rugby, UK, and covers the British Isles and much of Western Europe. Other local time and frequency radio broadcasts include: TDF, France, and CHU, Canada.

NTP Versions

The current release of NTP is version 4. The only significant modification to the protocol between versions 3 and 4 is a slight header re-interpretation to accommodate IPv6.

SNTP Simple Network Time Protocol

SNTP is a simplification of the Network Time Protocol, where the complexities of the full-blown protocol are not required. SNTP can be implemented when the high synchronisation performance of NTP is not required. The message format of the SNTP protocol is almost identical to that of the NTP protocol. However, the complex subroutines designed to maintain a highly accurate synchronised time are removed or simplified. Small computers with reduced processing power, such as micro-controllers or monitoring equipment most often use SNTP. The SNTP and NTP protocols are fully interchangeable, a SNTP client can synchronise to a NTP server without any issues.

More Information: NTP RFC’s

The original Network Time Protocol was introduced in RFC 958 (Request for Comments: 958). The full NTP version 3 protocol and synchronisation algorithms are described in RFC 1305. The SNTP version 4 protocols are described in RFC 2030.

Error 1201 In Information Store Using Exchange Server

Posted July 20, 2018 By www-2016nf-com
evolution-of-computers

Exchange Server follows transaction logging system. Information Store folder is comprised of related transaction logs along with storage groups. It means that Information Store is the most critical part of Exchange Server. Number of storage groups may vary according to the requirements of organizations and Exchange Server version being used. If the Information Store suffers inconsistencies or corruption, EDB Recovery will recover lost data in the absence of online backup.

Priv.edb and Pub.edb are two critical files of Exchange Server Storage Group. These files contain user mailboxes. If these files get corrupt, Exchange Server may return 4294966095 error and Information Store service may fail to start. The corresponding event entry in Event Viewer is -1201.

Apart from EDB corruption, -1201 Event ID may also generate if log files and EDB files are on different drives and due to some issues, log files are not available. To resolve the issue, user can follow these steps:

If online data backup is available, user can restore Information Store from it
If Information Store backup is unavailable or incomplete, user needs to use Eseutil repair utility to perform Hard Recovery. The process requires two basic considerations: backing up Mdbdata folder to avoid further data loss and ensuring that hard disk contains sufficient free space for Hard Recovery. Mdbdata folder contains all log files and storage groups of Exchange Server. However Exchange Server Repair requires following commands to be applied:

eseutil /p /ispriv /tx:tempdfg.edb
eseutil /d /ispriv /tx:tempdfg.edb
isinteg -fix -priv -test alltests
eseutil /p /ispub /tx:tempdfg.edb
eseutil /d /ispub /tx:tempdfg.edb
isinteg -fix -pub -test alltests
If problem persists, third party Exchange Server Recovery applications can be used on Mdbdata folder to repair damaged EDB files. These are the tools that can scan and repair damaged EDB files and extract user mailboxes without affecting data integrity.

Stellar Phoenix Mailbox Exchange Recovery is the most powerful edb recovery software. It extracts user mailboxes from damaged EDB files and restores them as individual PST files which can be used with Outlook. It supports Exchange Server 2003, 2000 and 5.5. It is compatible with Windows XP, 2003 and 2000.
Exchange Server 5.5
where x: is the drive containing the required free disk space.

NOTE: When the Information Store service has started, after the repair process, make a full online backup immediately.

Java Programming For Jsp

JSP is stand for Java Server Pages. It is an open source Java programming language that is easy to use and maintain. It is normally used for creating dynamic web pages based on HTML/XML. This JSP development language can be used even in lack of Java knowledge. The USP of this language is its rich depository of tag extensions, which are pretty simple. Also, this app enables programmers to integrate tag handlers.

It is a server-side programming language which uses simple tag-based codes from HTML and XML. With JSP you can create dynamic and interactive web pages that are performed independent, meaning that by all rights they should appear accurately and the similar on every computer screen, regardless of the platform.

There are basically two aspect are there when we discussed on JSP. One is Scriptlet and Markup through HTML or XML. These both terms point out two different syntax which used in JSP.

Scriptlet code block do not need to be concluded in the immediate block but it can be concluded in the later block. JSP code assessment, validation and compilation are done with dynamism which means run time. This run time anthology is not getting frequently repeated every time but only when there are any change to code. Java Developers should be aware of the thing that JSP syntax adds additional XML tags as a part of JSP action.

Advantages of JSP Hosting

1.Developers can easily maintain web pages with the help of JavaServer Pages Standard Tag Library (JSTL) expression language. The JSTL is used instead of any other scriptlet languages.
2.Most of the JSP Web Hosting Company provides 24/7 supports for their clients.
3.Not have any unwanted text or banner ads placed on ones website with JSP hosting.
4.One gets more disk space and data transfer, one can add more files to ones website and it can also handle more traffic.
5.Offering FTP access.

In other words JSP permit web designers to merge vigorously generated HTML in with their standard, static HTML code. The majority CGI programs need you to create the whole website in the one program, Where JSP allows you to compose the dynamic feature and the static feature of your site separately.

A microcontroller is a computer-on-a-chip or a single-chip computer. Micro suggests that the device is small and controller tells you that the device might be used to control objects, processes or events. Another term to describe a microcontroller is embedded controller because the microcontroller and its support circuits are often built into or embedded in the devices they control. You can find microcontrollers in all kinds of things these days. Any device that measures, stores, controls, calculates, or displays information is a candidate for putting a microcontroller inside. The largest single use for microcontrollers is in automobiles. Every car manufactured today includes at least one microcontroller for controlling the engine and additional systems in the car. In desktop computers, you can find microcontrollers inside keyboards, modems, printers and other peripherals. In test equipment, microcontrollers make it easy to add features such as the ability to store measurements, to create and store user routines and to display messages. Consumer products that use microcontrollers include cameras, video recorders, compact-disk players and ovens.

The Intel 8051 microcontroller is one of the most popular general purpose microcontrollers in use today. It is about 30 years old and still very popular. One of the reasons for popularity of 8051-based microcontrollers is the availability of many excellent compilers, from freeware applications to high-priced professional development tools. The memory structure of the 8051 microcontroller is a complicated and you will definitely need an 8051 microcontroller tutorial to go deep into the concept.

The main reason for their great success and popularity is a skilfully chosen configuration which satisfies different needs of a large number of users allowing at the same time constant expansions. Besides, the software has been developed in great extend in the meantime, and it simply was not profitable to change anything in the microcontroller’s basic core. This is the reason for having a great number of various microcontrollers which basically are solely upgraded versions of the 8051 family.

A very popular programming language is C. It is widely used in development of operating systems, desktop applications and embedded systems. Beside assembly language, C is the most popular programming language used for embedded programming. C for 8051 microcontrollers has been the number one choice among programmers. 8051 microcontrollers are no exception. SDCC is the most popular open-source C compiler for 8051 microcontrollers. The importance of such microcontrollers is attracting many a professionals to take up 8051 microcontroller tutorials. These tutorials demonstrate how to code simple input & output. The tutorials assume basic knowledge of programming and electronics. Massive use of embedded microcontrollers encourages engineers and students to join microcontrollers’ tutorial and training for c programming for embedded microcontrollers so that they can grab new opportunities in the process of development.

Todays sophisticated computers are developed as embedded systems so that they can be complimentarily used in mobile devices and electronic appliances. The microcontroller turns out to be the key element in an embedded system. Actually a microcontroller is a microprocessor giving more emphasis on the input & output operations. It controls the operation of electronic devices by giving them access to communication, measurements and switching information. Thus a microcontroller is regarded as a device controller. Intels 8051 microcontroller is among the oldest members of the microcontroller family, yet is very popular among users. Technical analysts attribute its popularity to its amazing architecture. Some of the reputed computer manufacturers like NXP, Silicon Labs & Atmel are still using 8051 microcontroller as the basis of their microcontrollers.

The 8051 microcontroller has a complicated memory structure that requires special software instructions to access it segment wise. Therefore special kind of compliers needs to be designed to make the memory accessible. Since the 8051 microcontroller is widely used in IT industry & many projects as well, companies have created their own 8051 microcontroller compatible compilers. As a result various kinds of embedded C programming compilers for 8051 microcontrollers are available in the market. Most of them are offered as part of a package along with debugger, simulator & integrated development environment (IDE). The Keil IDE/compiler is one such popular variety. Similarly SDCC (Small Device C Compiler) is a free & popular compiler that is found compatible with Zilog Z80, Motorola 68HC08, Maxim 80DS390 & Intel 8051 microcontrollers. The open source software code of SDCC is distributed under the guidelines of GNU General Public License.

Though pascal language is rarely used in embedded C programming, a few special Pascal compliers are available for the 8051 microcontroller. The Turbo51 & KSC Pascal51 are good examples of commercial Pascal compilers. Turbo51 is a free complier based on fast single pass & advanced multi-pass optimizing technology & using syntax of Borland Turbo Pascal 7.

While there are not enough options in basic or Pascal compilers, the C compilers are available in abundance. Users are facing difficulty in finding good quality basic or Pascal compilers for 8051 programming. The chief function of the compilers is the code they produce which should be optimized well to enhance the speed & size. However it is not the programming language in compilers which decide the size of the program codes for achieving specific tasks in 8051 programming. Either Pascal or C can be used to generate an optimized & compact code. It is the programmers preference on which platform he/she will feel comfortable working in.
