General Concepts about Object-Oriented Programming

The programming style that we usually call object-oriented programming (OOP) has appeared relatively recently in the history of programming languages. This is a particular and very convenient style for many situations. It was designed to overcome the limits of structured programming based mainly on the widespread use of procedures, functions, pointers or other more or less developed data types.

Although structured programming is very practical for small software systems or reduced non-graphic applications, it should be avoided when dealing with large applications that use graphic elements where object-oriented programming is recommended. Object orientation means organizing software resources as a collection of distinct and discrete objects, which includes both data structures and their processing functions. This organization is an extension of structured programming in which the data structures and processing functions are only loosely connected. All items have their own identity and are perfectly distinct.

An object is defined as an abstract concept, a specific and useful element for any application. Objects serve two specific purposes:

– they provide a better understanding of the problem to be solved;

– they provide a base design for implementation.

A class of objects encapsulates a certain number of objects with similar properties. This similarity refers to both the description (data and attributes) and the behavior (functions or methods). Attributes are unique features within an object class. Each attribute receives a certain value which can be modified during the objects life cycle. Two or more objects can have the same or different values for the same attribute.

Methods or operations are processing functions applied to objects of a certain class. All objects within a class admit the same set of methods, methods which in return may receive any number of additional parameters. In order to apply various methods to an object, it has to be created (defined). Defining an object is called instantiation. Once an object has fulfilled its mission it is removed.

Abstraction is a fundamental human trait that allows us to build models and thus cope with complexity. In every field of human activity, project approach is based on building a model for a better understanding of the problem to solve. Software engineering makes no exception. Through abstraction the essential key aspects are isolated from the non-essential ones. Therefore, each problem might have several adequate models.

In the software engineering industry, structured programming has made a big step forward defining three perspectives needed in order to properly address any application. These perspectives, also known as models, are: the static model, the dynamic model and the functional model.

There are currently several object-oriented methodologies used for analysis, design and implementation of software resources. One of these modeling methodology is the OMT (Object Modeling Technique) methodology. This method of modeling involves the planning of the various development stages and a graphical representation of objects and their relationships.

You Can Not Run Microsoft Exchange Server Services After Event ID 7011

Is your Microsoft Exchange Server 2000 system behaving unusually? Are you unable to start various Exchange Server services? Is your EDB (Exchange Server Database) inaccessible? Such behavior indicate Exchange Server database corruption, which may occur due to a wide range of reasons, ranging from simple user mistake to catastrophic system crash. It leads to critical data loss and needs Exchange Recovery to access your mission critical data.

Consider,
A) You get Event ID 7011 while working on Exchange Server.

B) The SMTP (Simple Mail Transfer Protocol) service on Exchange Server computer stops responding or terminates improperly.

C) System freezes when you run – IISADMIN, W3SVC, IMAP4SVC, RESVC, and POP3SVC services. You need to restart your computer when it occurs.

D) The services fail to stop when you try to stop and restart them.

E) You may encounter error messages, similar to the followings:

i. Timeout (30000 milliseconds) waiting for a transaction response from the RESVC service.
ii. Timeout (30000 milliseconds) waiting for a transaction response from the IISADMIN service.
iii. Timeout (30000 milliseconds) waiting for a transaction response from the W3SVC service.
This behavior of Microsoft Exchange Server renders your valuable data inaccessible. In order to get your Exchange Server data back, you need to first identify the root cause of this problem and then fix it with Microsoft Exchange Recovery.

Grounds of the issue

You may come across this behavior of Microsoft Exchange Server due to any of the below reasons:

1. A message is received by the MS Exchange Server 2000 system, which has a damaged time stamp.

2. The message has an invalid FILETIME attribute.

3. Exchange Server database is corrupted due virus infection, improper system shutdown, and application crash situations.

Resolution

Microsoft has a hotfix for this problem. You can download it from Microsoft’s website and install it on your MS Exchange Server computer. However, it can not fix the database corruption problem and the database remains inaccessible. In order to solve database corruption, Exchange Server Recovery is needed.

You can easily repair and restore damaged EDB file using Exchange Recovery Software. They are powerful enough to systematically scan the whole database and extract all damaged mailboxes from it. They extracts all the mailbox objects such as emails, notes, contacts, tasks, calendar entries, and more.

Exchange Server Recovery is an easy-to-use and safe exchange database recovery application for insured recovery of damaged database. The software works well with Microsoft Exchange Server 2007, 2003, 2000, and 5.5. It also recovers deleted Exchange Server mailboxes.

Starting a Private Server – Attracting Players, Having Fun, Profiting

Many individuals have the desire to own a private server. However, you will acknowledge that it is quite an onerous task especially having in mind that there are others more established in this line and already incorporate more players. However, you do not have to fear competing with them.

To start with, it would be important that you acknowledge that the Servers have larger player bases simply because they have spent much more time in the system. In this case, they have incorporated some marketing strategies that have guaranteed them a clear customer or player base. When you are launching private server, it would be imperative that you ensure that the player base is thoroughly entertained in which case, they will be in a position to feel that they own the process and are not just part of money minting machine.

There are three things that you would need to incorporate however.

Start off by acknowledging the things that you would require to set the private server. In this case, you would look into issues like money, the hardware as well as connections. In addition, consider the necessary technical expertise that may be required and especially the financial implications. While on this, determine the private server type that you will be running. This will be determined by the topic and content of the server as well as the things that you care for. Please, do not go with what is popular in the market while you do not care about it. in addition, it would be important that you determine the necessary documentation for a private server. In this endeavor, you would be paying attention to the content of the server would be imperative as it is this that will attract players to your server. You can always hire out someone to create the script or content of the play. However even as they create it, it would be important that you have some knowledge as to how it is operating so that your input may be incorporated.

Creating the script or content of the play is only part of the development. You definitely will need to be updating it from time to time in order to keep in line with the current updates provided by the emulator.

Secondly, you would need to incorporate a genuine care for the server. While talking of the server, you would be looking at the sever, the players, the content etc.

After you have incorporated these things in your server, you will be in a position to generate enough traffic. From this, you would be able to profit by encouraging the players to make donations. The donations may be made in exchange for services or items

NTP Server Systems The Network Time Protocol

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.

Tips to Optimize WordPress Running on Dedicated Server

This is a comprehensive guide or bunch of tips to Optimize WordPress Running on Dedicated Server. Though Dedicated Server is becoming a historic hosting option as Cloud Servers are currently dominating the most of the useful and successful blogs, still there are users who use dedicated servers and these few tips to optimize WordPress might help them.

Tips to Optimize WordPress Running on Dedicated Server – Reduce the Database Server’s burden/b>

In case of a dedicated server, the database server is actually running on the same physical server and using the same physical resource. MySQL has gone away, 508 resource limit reached messages are quite common due to increased number of plugins which are eating up the php memory. In case of a Dedicated Server, you frankly can not increase the php memory after a limit, which a Cloud Server easily can do as the cloud server’s RAM and Bandwidth is virtually not limiting.

These happens probably due to the fact, all the plugins try to use wp-cron.php or other same core file simultaneously. To avoid it, use database cache plugin plus reduce the number of not-so-needed plugins. If you need to reduce a plugin, which is SEO wise harmful – try to increase the php memory.

Tips to Optimize WordPress on Page Speed Score

Your WordPress blog should load within 2 – 3 seconds with a Page Speed score (by WebPageTest) should be over 90/100.
Using a Content Delivery Network, a Cache Plugin, some htaccess tricks can do it easily. All these, directly reduces the load on the main server.
Use an optimal theme, Thesis and Genesis framework with optimized child theme are among the best performers. Read our previously published tips to Optimize WordPress on the page speed front.
Use a cache server if needed

Tips to Optimize WordPress on the backend

Its quite bad if the WordPress backend is slow despite the fronend is fast – it simply increases your fatigue. You can use CDN to offload the static files, increasing the php memory.

Tips to Optimize WordPress Running on Dedicated Server

Frankly, there is no meaning to use a dedicated server for a WordPress blog now. Cloud Server and cloud Hosting from Rackspace or other reliable hosting brands not only reduces the cost, but also gives the pay as you go model, ensuring that your WordPress will never be short of Physical RAM or Bandwidth.

Dedicated server is probably a good option where a bit more security is needed – our usual blogs has nothing to hide, all pages are actually public; but still for a secure server, one must think of a colocation server rather than a dedicated server.

Also, a Virtual Dedicated Server is a very good cheaper alternative, sometimes a VPS can outperform a Dedicated Server at the same cost or less.
