REST (representational state transfer) is a process for getting information content from a Web site by reading a designated Web page that contains an XML (Extensible Markup Language) file that describes and includes the feasible content. For example, REST could be used by an online publisher to make syndicated content available. Periodically, the publisher would prepare and activate a Web page that included content and XML statements that described the content. Subscribers would need only to know the URL (Uniform Resource Locator) for the page where the XML file was located, read it with a Web browser, interpret the content data using the XML information, and reformat and use it appropriately (perhaps in some form of online publication). Now question is that why doesn’t the REST programming section include any code? It is largely because REST is more about a mindset rather than code, more about design than implementation.It may look simple, but there are few vital points to keep in mind while developing applications in the REST style. Think about the business problem in respect of resource manipulation rather than Application programming interface design. Enabling web services requires making data available for use by applications without knowing ahead of time exactly how that data will be used. Start by modeling the persistent resources that is to be exposed. There must have a single, unambiguous, authoritative identity within a system in order to identify all the conceptual entities that the system exposes as resources and to assign a unique URL to each of them. In case of temporary resource you should be very careful if you plan to use them only as a temporary resource. Publicly exposed resources should be sorted out that are immutable by the client and those are mutable. Putting and deleting should be used in appropriate manner. Proper methods should be implemented that will allow both sender and receiver to make the absolute minimum of assumptions as to the other’s state.Single logical operation should not be implemented when there are multiple requests. Applications that need to be expects, accepts and returns should be properly documented. A good specification of the representational schema of both mutable and immutable resources with a formal mechanism should be there (for example, XML Schema, DTD, Schematron, or RelaxNG). There should be a proper description and documentation of the resources that can be accessed by using a “gradual unfolding methodology” to expose data for clients. Proper linking to other related resources in every representation to enable clients to drill down for more information should be there.You should know how to use the software to setup a server that can do content negotiation, authentication, authorization, compression, caching, vacuuming and house cleaning. A proper abstractions should be there so the implementation can be carried out in a good way. If there is abstractions then it can survive the storm of change from different implementations and new technologies. Representational State Transfer REST Architecture

When analyzing the present market trend the demand for computer programmers is increasing each day. There are Associates online Degrees, online Bachelor’s and Masters degree and even online PhD Degree.

In the year 1950 FORTRAN language was developed and then came COBOL which was the first language used for commercial application. In the year 1996 for teaching the undergraduates BASIC was introduced. C was developed by Dennis Ritchie of Bell Laboratories. The most widespread computer languages are C++ and JAVA. With a lot of these computer languages and the need of other application development tools the demand for programmers has increased. Presently there are also some active tools for developing applications like Visual Studios, Eclipse and ERP. You can also have a great career in graphics if you are interested. Therefore you can either have a career in software as a software engineer or as a graphics cad or cam designer.

If you are interested in computer programming you can easily build up a career in banks, research organizations, hospitals, schools etc. It is not necessary that you need to work in a software company if you are a programmer. The government will also offer jobs for computer graduates and post graduates. There are a variety of fields inevitable with computers nowadays. The computer languages that are presently in demand are Microsoft.Net, Asp .Net, VB .Net, C# and J2EE. As the technology advanced the programmers need to update their knowledge in the field.

What Is A Name Server

Posted March 15, 2019 By gbjwm

The computer cannot understand English or any other common language. The internet is a network of such computers that do not understand the language that the common man understands. This means that a domain name typed in like www.yourdomain.com will not mean anything to the computer. This domain name that you type in needs to be translated into a string of numbers for the computer to understand it. This string of numbers is called IP Address. It looks like this: 202.157.34.10.

It is not easy to remember a string of numbers like a domain name. Hence, we use domain names that we can understand and those domain names have corresponding IP Addresses that the computer can understand. But if this has to work, then every domain name should be translated into an IP Address that the computer understands. This translation is done by Name Servers. A name server is familiar with a domain name and their corresponding IP Addresses. Name Servers are also called Domain Name System Servers or DNS Servers.

All the information from all the name servers around the world is stored in a central registry. It takes between 8 and 48 hours for all the information to be updated in the central registry when a new domain name is registered. Name Servers from around the world can access this registry and when the domain name is requested, they can get the corresponding IP Address from this registry.

A domain name, when registered, needs at least two name servers. These are usually ns1.nameservername.com and ns2.nameservername.com. Here, “nameservername” is the name of the server. The first one is the primary name server and the second one is the secondary name server. The secondary name server acts as a backup that comes into effect only when the first name server is not responding.

Certain steps need to be followed while registering a domain name. These may differ a little depending on the registrar, but most of the steps are the same.

If you need to register a .com domain name, the steps are given below :
1. You get an account with the domain name registrar when you register a domain name. Log into your account with the registrar.
2. You will see an option to manage your domain name within your account console.
3. Select the domain name for which you want a name server. This will open a page for managing the domain.
4. Select “add name servers” on this page under the name server details section.
5. Enter the name and IP Address of the new name server and click on “Add”.
6. You should get a confirmation message indication that you have added a new name server once you are done with registering it.
7. Normally, you can start using the new name server immediately.

Benefits Of Print Server

Posted March 14, 2019 By gbjwm

Print server is basically a computer or device which is connected to one or more printers and to client computers over a network.It can accept print jobs from the client computers and allocate the jobs to the printers.
Print Server Advantages
Benefits of print server are enlisted as:
Print server lowers the administrative and management workload due to centralizing local and remote printer management. It allows prioritization of print jobs. It is known that priorities can be assigned to print jobs such that more important jobs are printed before those less important.

Print server allows an administrator to manage and control access to each printer. There are three level of printer permissions, print, manage documents and manage printer. Print permission allows a user to print documents, pause, resume, start and cancel his documents. This permission is granted to everyone in the group.

Manage documents permission is assigned by administrator to selected users when required. With this permission, user can control job settings for all documents. Manage printer permission allows the user to pause and restart the printer, share a printer, adjust printer permissions, change printer properties and change spooler settings.

With the use of print server, client computer jobs are quickly spooled to print server as compared to printer. The main point is that while printing large jobs from an own printer, user may have to leave his computer running until printing task gets completed. But with the use of print server, if any job has been spooled to it, then user can shutdown his system.

A system administrator can easily manage printers with the print server. If your own printer goes down, then you will not be able to print documents. But with the use of print server, when a printer goes down, then the printing job is transferred to other printer.
Print server manages workload on printers such that if one printer has lots of printing jobs, then it will assign some of the jobs to other printers in the network. It means if your printing job is spooled to print server, then it will get completed.

What Is Python Web Programming

Posted March 14, 2019 By gbjwm

The python programming language is a modern web programming language that was originally conceived and developed by Guido van Rossum in the 1980s. Since that time, Python has evolved into a high-performance programming language that is modular and extensible. Some of the largest websites in the world are utilizing Python such as YouTube, Disqus, and Reddit. Python offers a number of features that make it an attractive programming platform including stability, portability, object-oriented development, a powerful standard library and a wealth of third-party modules or packages.

Stability

Python has been under active development since the late 1980s and is considered a mature programming language. The developers of the Python language conduct extensive functionality and regression testing to ensure the language remains bug-free and stable with each new release.

Portability

Python programming offers a number of features that make it an attractive option for web application development. Python applications are portable due to the fact that python interpreters are available for all modern operating systems and some embedded computing systems.

Object-oriented Development

The object-oriented nature of Python makes it an ideal first language for new programmers and easy to learn for programmers migrating to Python from other object-oriented languages. Python programming is intuitive and reinforces good program structure and object-oriented methodologies.

Standard Library

The standard Python library offers developers a plethora of features comparable to more complex languages such as C++ while maintaining simple and approachable language syntax. Comprehensive file-based I/O, database interactivity, advanced exception handling and a host of built in data types make Python appropriate for both web applications and general purpose programming. This makes python web programming an easy task for application developers seeking to transition to web application development.

Third Party Modules

Python is known for being a comprehensive language with extensive functionality included in the standard library. However, the growing popularity of python programming has led to a vast array of third-party packages, or modules, that extend Python’s functionality and allow the language to deal with unique programming challenges. For example, modules are available for handling non-standard database interactions and advanced cryptography functionality. There are also modules available for dealing with common tasks such as reading file metadata, rendering charts and compiling Python applications into standardized executable applications. Python web programming is made easier due to the availability of many web-centric modules to handle tasks such as e-mail, maintaining HTTP state, interacting with JavaScript, and other common web development tasks.

Having a server is something which many people dream about. Unfortunately, very few of them manage to provide themselves with dedicated server web hosting. Nobody knows that the reason for that is. Perhaps, it is because most of the people think that the dedicated web server hosting always involves a lot of money and expenses.

Having a server is something which many people dream about. Unfortunately, very few of them manage to provide themselves with dedicated server web hosting. Nobody knows that the reason for that is. Perhaps, it is because most of the people think that the dedicated web server hosting always involves a lot of money and expenses. However, we can completely argue that statement since being provided with good-quality web hosting is something which everyone deserves and everyone can achieve.

Of course, it is sometimes quite difficult to choose among all these server web hosting offers on the Internet. The truth is that everybody promises that their server is the best, the most preferred one but in reality- things are quite different. Basically, it is the main reason why people feel so confused when it comes to choosing dedicated server web hosting.

Undoubtedly, one of the peoples main problems is that they have no idea how much the dedicated web server hosting is supposed to cost. The lack of such important information is the real reason why there are so many people making the wrong decision. So, the question about the cost of the web hosting is going to be answered right now! Basically, the so called dedicated server web hosting costs between $49 and $100. There might be some offers which are out of this range but it could be claimed that 90% of the web hosting proposals offer a cost between $50 and $100.

What can we claim about the offers in this diapason? Well, there is no doubt that those are the offers which people should count most on! Why is that? It is because the price between $50 and $100 is completely normal for web hosting services. However, if you are offered to pay below $50, you can really doubt that these are cheaters- they will either take your money and never respond again or will offer web hosting services of extremely high-quality! But people who are offering web hosting services above $100 are very likely to be cheaters also. What they might be promising is web hosting of extremely high quality but what you may receive instead is nothing!

If your current Dynamics GP Great Plains server got to be replaced with new hardware, you should follow procedures to move Dynamics GP databases as well as FRx reporting system files. Being working for major Great Plains Dynamics GP VAR in US, we realized that our large customers are following this simple technique: place new server with newer Operating System (such as Windows 2003 instead of old Windows 2000), install SQL Server 2000 or 2005, move Great Plains DYNAMICS and all companies databases, move user logins, password and security access (you can also find these SQL scripts at Microsoft Dynamics Customer Source). Then shut down the old Dynamics GP Server, rename new server to its old server original name, and off you go! Well, this is about Dynamics GP Great Plains. FRx Financial reporting is more sensitive to UNC Path, Shared Folders and mapped drives. If you ran into these issues, this small publication is dedicated to you:

1.FRx Sysdata concept. Please login FRx reports designer, under Admin->Organization->SYSDATA you should see where your current FRx metabase is located. Please, know that FRx is compatible with multiple ERP platforms: Great Plains, Axapta, Navision, Solomon and these are the reasons to lean on file location. Sysdata folder has FRx metabase and if you change settings for your companies: Company->Information: Specification Set, Import and Export Path, Rates Database Path (in case if you deploy multicurrency in GP and FRx) all the users will be updated

2.FRx System Specific Information. Here you have ODBC DSN, usually FRx deploys the same DSN as Dynamics GP Great Plains Workstation. For Each company please specify system database: DYNAMICS and company database

3.Admin View OFSI Settings. In our practice, OFSI tables were source of the problems with earlier FRx versions: 6.5 and down, These were the days in late 1990th where you would have to create OFSI tables manually in SQL Query Analyzer

4.G32 files error messages. The concept behind is pretty simple FRx rebuilds GL indexes on logon. If you are getting error message, that you can not login FRX due to G32 file is locked, please open your sysdata directory, rename all G32 extension files and come back to FRx this should fix the problem

5.If you are at the point where you are considering to give up on FRx issues, we understand and respect your position consider to give us a call

Cooling a Server Room the Cost-Efficient Way

Posted February 26, 2019 By gbjwm

As the servers are used constantly, they generate tremendous heat. When this heat increases beyond control, it may lead to damage of the devices and equipment. Being machines, the computers are delicate under the hood and are prone to damage due to carelessness. System crashes, reboots, hang-ups, untimely failures; poor performance and other problems can be created due to abnormal temperatures. Now, one way to keep these issues under control is to maintain the server room’s temperature. Sufficient ventilation, cooling and maintained temperature are the efficient ways to protect computers and servers.

Maintaining the temperature

The computers used at homes and for small offices come with internal cooling devices, which usually keep the desktops and laptops cool. Nevertheless, the server rooms that manage a number of systems do not have sufficient internal cooling systems. They have to be kept cool using an external cooling source, such as portable air-conditioner. Secondly, increased humidity inside the enclosed area can cause corrosion or rust. The maximum humidity level of a server room should not exceed 40 to 50 percent.

Are portable air conditioners good solutions for cooling?

The temperature of the server room should be steadily cool around-the-clock. If the room or storage area is connected to the central cooling systems, they may be shut down during the weekends or sometime late at night, depending upon the company’s working hours. If the cooling systems fail, the computer systems are prone to face the brunt.

Portable air-conditioners keep the server rooms cool, as the temperature can be controlled individually depending upon the outside temperature. There are few air-conditioners that adjust the temperature according to the outside temperature on certain modes. They are self-contained units which do not require permanent installation. Business owners can move these units anywhere as required.

A portable AC used in such places must have condensation tank to manage the humidity level, automatic restart function and proper ventilation to replace the hot air inside the room. These features not only keep the servers cool but also regulate fresh air and keep the machines working continuously. The automatic function keeps the air conditioners working continuously even when there is a power cut or failure.

When it comes to the size of the air conditioners it is never an issue. The server closet of size 9000 to 12000BTU will be sufficient for the unit to fit in. While a 12K BTU unit requires 9 to 12 amps a huge unit of 14000BTU requires 20 amps. The air-conditioner should be thoroughly checked for the necessary requirements before installation.
