Discover The Truth About Eve Online Private Servers

CCP Games developed a massive server cluster to support the thousands of star systems and millions of unique objects that EVE Online, their flagship MMORPG, requires for it’s shared game universe.Their server system is so robust that they schedule a one hour down time every day to run backups, and the system can handle up to 25,000 players (and sometimes more) without collapsing.
|Despite supporting over 50,000 simultaneous users, the server cluster requires just one hour of downtime a day for maintenance.|Only one hour a day of maintenance is required for this monster server cluster, which is designed to scale to support over 50,000 simultaneous users.|With over 50,000 users logged in at peak times, the server cluster can cope with node failures, hardware crashes, and still keeps on going – with only an hour of maintenance a day.|A daily downtime of an hour a day is all that’s required to keep this giant server cluster running, supporting over 50,000 users at peak times.[/spin]
Because of the gigantic size of the database that players interact with, EVE Online doesnt lend itself to private server play, and there are no EVE Online private servers.
Although some might disagree, the player experience actually benefits from a lack of EVE Online private servers.However, the lack of EVE Online private servers benefits players and helps with the game experience.No other game boasts as many simultaneous users in such a large shared universe, and this is the real appeal of EVE Online. Because EVE Online runs on a single cluster, there’s never a choice, like in World of Warcraft, or City of Heroes, to decide which server you’re going to be on based on the server your friends are on.
You’re either on the Tranquility server (if you use the English language interface) or the Serenity server (if you’re using the Chinese language interface), and there are usually ten thousand or more players on simultaneously to interact with. Singularity, the test server run by CCP, is the third server cluster, and all players are recommended to install a test client and give input to the game’s development.

By contrast with World of Warcraft, there are dozens, if not hundreds, of private servers out there, that will let anywhere from a hundred to maybe a thousand players log in simultaneously. For WoW, this is an opportunity to “grind in private”; if you tried doing that on EVE Online, you’d have a hard time hooking up with other players at all, due to the massive size of the universe to explore.
Luckily for CCP, an EVE Online private server is beyond all but the largest research institutes and supercomputer sites – most people don’t have solid state drive arrays and massively parallel servers at home.

Amadeus Consulting Discusses Do It Yourself App Programming

Another issue is software support. Since your tools are limited, supporting and troubleshooting your application can be very difficult, and it can be a very manual and time consuming task to find and fix bugs. This makes it a very unwise choice for commercial applications (such as creating an app to sell, or a website to promote your business and engage your customers), but can still be suitable for more personal use.

In terms of helping you learn programming, requiring you to find and fix bugs can be very helpful, as you must learn and understand what is going on. But for people looking to quickly create something useful, this can be time consuming and frustrating.

Also listed under “the bad” is the over-estimation of what you can build with little or no programming experience. These tools allow you to build the core framework of very basic applications, with strict limitations on the features you can include (although some allow elements to be added at the code level, but that requires an amount of expertise). What many users find missing is the ability to manage the final look and feel of an application, which can be almost as important as the functionality of an application.


Do-it-yourself programming tools can be a great way to learn and experiment, but require a lot of learning and have many limitations which restrict your ability to create professional-quality applications.

As a custom software development company based in Boulder, Colorado, we are often asked if these types of tools are a threat to our core business. The answer: definitely not. These tools help people better understand the time and expertise required to make quality applications, and they help build interest in the technology itself.

Many people and small companies are interested in do-it-yourself options because they hope it will save money over hiring someone else to do it. However, there are many other options that may be better suited to commercial needs, that wont break the bank. Some of these include semi-custom websites, and simple mobile apps which are designed from a prebuilt template, but then customized to fit a specific need.

These other options can also benefit from customization by experienced programmers, which can help ensure that it meets all of your needs and can be easily expanded as your company grows. One example of this is the Virtuoso Website Builder and Support which offers not only customized websites, but also 24/7 support, cloud hosting, SEO, and many other benefits. The sites are based off common templates but still benefit from an entirely customized look and feel. This saves time and money without reducing quality.

As a custom software company, we appreciate anything that helps people understand technology and become a part of the creation process. As people continue to imagine and experiment, we will continue to specialize in helping people translate those dreams into reality.

How To Make Your Server Secure

In todays world, every internet user knows that it is mandatory to have secured servers. You have to ensure for the security of your web servers so that potential hackers do not stand a chance as there will always be someone trying to have unauthorized access. Server security is very important as you do not want unauthorized access to your company information as there are times you may have to put very delicate company resources on the server. To be able to create a safe environment for your online resources, you need to be in the know of the current internet trends so that youre updated on the direction that internet professionals are taking . For this case, you need to know of the latest server security software that can keep hackers at bay whenever they strike.

You need to have adequate server security if you want to operate online. A common and useful method used by internet professionals in server security is by changing the port of access. Whenever you constantly change your port of access, you get to further secure the data you have stored on the servers. Changing the port of access has also been known to greatly reduce cases of fraud or theft of credit cards.

Apart from the system that involves changing the port of access, there are other important things that you can do to improve your server security like setting up your server firewall . Hackers are able to switch off the system firewall remotely so ensure that you constantly ensure that the firewall system is always up . There is a phrase is server security called hardening . This term refers to the removal of unnecessary software on the hosting machine so that only the software required for hosting services is left installed. This helps to free up the servers memory and it also enables you to easily monitor for any unwanted software from trying to creep into the system. When you know the necessary software installed, you can easily detect unwanted software and immediately get rid of it to restore your security . Server security can also be ensured by use of software that scans the system trying to detect weak points. Such software is very useful as it not only detects the open ports but it also has mechanisms of closing the unseen open gaps.

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.

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.

Learn Use Of C Microcontroller Through C Programming For Microcontrollers

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.

Best Server Maintenance How To Do It Correctly

Sometimes, expressions like -the server has broken down’ can cause dread in the network supervisor’s heart. Just as a good parent looks after his or her children even when there is no obvious danger, a good network manager should also observe the servers to confine prospective issues prior to they come about. If we talk about the outsourced IT support, it is a key to the triumph of any company that depends on a network of computers for its everyday operations. For these companies, computer maintenance turns out to be essential.

Let us take a glance on systematic guide to right server maintenance.

First thing the administrator needs to do is intend usual server troubleshooting & maintaining practice. To facilitate the maintenance of the server more proficiently, you require having an average troubleshooting process that you will tag on every time you are maintaining it. Make use of a checklist to help in your troubleshooting & safeguarding procedure. This will avoid you from failing to notice something.

Next important thing is to settle on whether the physical element is carrying out correctly. This takes in inspecting the hardware, cabling arrangement and any connected sideline. Turn off the network cables & cards to assist recognize any errors in the hardware. In case, there is any fresh hardware in the server, then ensure that it is well suited with the operating structure.

After that, you should look out for addressing & routing issues in order to control the traffic. A sincere attention towards the design of your operating structure is important. Standard business networks run on TCP/IP, therefore a faulty TCP/IP setting can cause address & routing problems. Always make certain that your server’s each TCP/IP design is correct.

We know that server applications are typically diverse from applications that are set up on computer units. Usually, the server applications are set up over the operating system and they let you to uphold and watch your server & the computers in the network. You require making certain that these applications are friendly with the essential operating system.

Furthermore, while troubleshooting the print server, you should ensure that your printer is working smoothly and that every connection is safe. Also, make certain that the printer drivers are set-up properly and the print spooler service is operating efficiently. In case of any crash in the computer, hard disk recovery becomes important which only a hardware expert can do.

Fundamentals Of C Programming For Embedded Microcontrollers To Benefit Beginners

An embedded device is a structure that links previously programmed software on a microcontroller integrated in the computer hardware. The software program is set up on the microcontroller, the brainpower of the electronic gadget. Every embedded device performs one particular operation. A complicated gadget such as a personal digital assistant (PDA) or smartphone may have embedded controllers that can manage multiple tasks. Nevertheless, embedded devices are not as complicated or programmable as personal computers. C programming for embedded microcontrollers is one of the most common phenomena these days.

C is one of the most widespread software languages employed on embedded device controllers. One prominent advantage is because it belongs to a selected class of software languages that is able to function on 8-bit microcontrollers as well as 64-bit PCs, implying that a lot of computer developers can code C software program for personal computers and embedded systems alike. C can also make use of extremely uncomplicated commands to manage the device, releasing the fixed memory of the device to embrace numerous lines of code or parameters. Both microcontrollers like 8051 and digital signal processors can have code written in C language.

A programmer writes code in C on his/her PC. Then, the code is translated into the machine language using a compiler on the programmer’s PC to create a software program. The software program in the embedded device may be run through a simulator as well. Subsequently, it is replicated onto the controller with the help of a programmer. In the end, the controller is tried out on a test bed to make sure that it functions suitably.

C is regularly used in the construction of embedded devices. Embedded devices are seldom coded with the aid of the C++ since they hardly ever have the memory space required for the complicated C++. C# is irregularly applied on embedded Linux systems.

Bluetooth products are coded in C. An embedded microcontroller like one implanted in the web camera is commonly coded in C language. Microcontrollers programmed in this language have also been integrated in LED or light-emitting diode gadgets and liquid crystal display (LCD) screens. USB devices are programmed in C too.

Embedded systems are put into use to have a control on electronic appliances like DVD players, mobile phones, watches and medical equipment. Other such systems such as video cards and network switches have their presence in peripheral devices. The speed control mechanism in a car is an embedded system as well. These implanted systems are cheaper than complicated processors because of their straightforwardness and regular mass production.
