The Ins and Outs of a VPN

Any business that expands to multiple locations around the world requires a fast and reliable way to keep its data accessible by its employees, and for employees to connect to company's servers over a secure line from a remote location.

VPN, or virtual private network, is a technology that enables businesses to accomplish its goal of data secure and connectivity. It's a private network that connects remote sites or users together using a public network such as the Internet. The prime reason for using a VPN is that secures the data and prevents anyone intercepting the encrypted data from reading it.

Understanding How the VPN Works

The internet is like an ocean, which has various islands representing LANs. Just as travelling from one island to another via a ferry isn't private, in the same way, the wires and routers constituting the internet are not private. Essentially, any connection between two private networks using the internet is susceptible to security issues.

For obvious reasons, a business that uses the internet has to protect its data, and that is where the VPN enters. It allows users to communicate using the internet and connect with a private LAN in a secure and reliable manner. VPNs can also be expanded to accommodate more users from different locations.

Common Types of VPN

A site-to-site VPN is one common type of VPN that connects multiple fixed locations. It allows a business to extend its network making computer resources available to employees from one location to another. A company that is growing its offices in multiple locations around the world is a perfect example of a company in need of VPN.

The Two Types Of Site-To-Site VPNs Include:

Intranet based
An intranet VPN can be used to connect each separate LAN to a single WAN. It is suitable for companies that have one or more remote locations to be connected to a single private network.

Extranet based

An extranet VPN can be built between two companies that are closely related and wish to connect its LANs. The extranet-based VPN will allow the two companies to work in a shared network environment, which is secure and reliable.

About The Company
VPNFinder.com is an online VPN service review company that aims to help internet users make the best decisions when choosing a VPN service. The website provides the best reviews, which include price comparisons, features, and the editor's review of the VPN. All the reviews are based on real time usage, and professional opinions.

One Quick Trick to Discover Amazon Browse Nodes

Amazon classifies each individual product within its catalog into numerical categories commonly known as "nodes." These nodes are then arranged in a meaningful and hierarchical manner reflecting "parent nodes" and "leaf nodes." A leaf node is a more precise and more specific sub-category of the parent node. In other words, parent nodes represent the most general classification of products and each leaf or "child" reflect a specific and relevant subdivision. For example, node 283155 is the parent node for "books," and node 5 reflects "computer & technology books" -- a specific kind of book. In this example, 283155 is the parent and 5 is the child or leaf. At the present time, Amazon boasts 100,000+ nodes. However, many of them are either inaccessible through the API or do not contain practical information.

The process of discovering all of Amazon's nodes is performed through repeated API requests. A minimum of one second should pass between each unique request for most associates. Since Amazon does not make available a master root starting point containing all parents, the process of finding all the nodes can be time consuming.

Because a master root list containing all parents does not exist within the Amazon API, the first step to creating a database of BrowseNodes is to obtain a list of diverse categories and their associated nodes. The most diverse list of categories found in one place is located on the "Amazon Site Directory" page. Obviously, this page would contain links to help search engines discover deeper product classifications and would represent everything Amazon has to offer. Most links on this page contain node-specific URL addresses, which are found using PHP. After non-essential HTML and duplicate references have been removed from the HTML and links, the condensed list gets saved to the mySQL database in the SampleNode_US table in the format of one node per row.

At this point, every row in the SampleNode_US table runs through the API once again. But this time the purpose is to determine each row's ancestor. Duplicate ancestors from returned API data are removed and the results are then added to their own database table, RootNode_US. In this manner, the root BrowseNode containing all parents is discovered through structuring the resulting data returned from the API.

Lastly, each row in the RootNode_US tables gets passed through the API in order to obtain children Browse Node IDs. Each child BrowseNode, in turn, also is passed to the API in search of deeper children. When no more children can be found, then the next parent node or child is loaded and run though. The process repeats until each node has been explored for all their children. Results are saved and/or updated in the Node_US table. It takes about 2-3 weeks for the script to parse all nodes after factoring in the required time delay between API requests.

The author programs code as a hobby and is a member of the Amazon associates program. Those interested in obtaining a database containing Browse Nodes are invited to like The aFeeds Database. Copies of the regularly-updated database are for sale for a nominal fee. The database is being used for demonstration purposes at the previous link.

Ways to Choose the Right Game Development Platform

Game development has grown popular owing to the engaging and exciting games developed of late. When it comes to game development, the first and foremost thing that game developers need to arrive at is the game development platform. Choosing an incorrect platform can lead to wastage of time, money, and efforts. Getting acquainted with a new development engine involves a lot of time and money. Choosing the right platform for game development is highly essential as it is one of the most critical decisions. To solve the dilemmas faced by developers in taking this decision, I am presenting this article comparing the features of Unity, Corona SDK and AndEngine. I will also justify the effectiveness of Unity over other game engines.

AndEngine:

Pros:

When you enter the keywords- Android Game Development Engine what you will get in the first search result is AndEngine. It is an open source platform used for Android game development. This lightweight and powerful game engine offers 2D development platform to game developers. Whilst supporting advanced OpenGL functionality, it delivers games native to Android. One of the major strengths of this game engine is its lightweight architecture and its amalgamation into Eclipse. It utilizes Java mostly.

Cons:

Despite its striking features, AndEngine is not well-maintained. Their website is akin to that of 2000s wherein there are a number of broken links. Lack of documentation makes using AndEngine a challenge for amateurs. Moreover, it works only for Android apps and this leads to consumption of more time and resources. Thus, it can rightly be concluded that this game engine will soon make its exit from the game field.

Corona SDK:

This cross-platform engine helps in development as well as publishing. A number of games have utilized it owing to the powerful features it offers. With Corona you need a single code to deploy the game on both iOS and Android. One of the major benefits associated with it is there are no charges for using it.

This game engine is well-known for its support and documentation. Apart from game apps it is also utilized to create business apps. It packages your code into an application which is compatible with most of the major operating systems. This is where it gains an edge over AndEngine.

Cons:

When it comes to cross-platform publishing one must be ready to give away a few dollars more. In order to interpret the code that works both with Android and iOS, Corona SDK makes use of its own programming language Lua, a variant of C#.

This is why it can easily be learnt by iOS developers. However, for other platform developers Lua is a challenge. In this era of rapid apps development wherein a developer is expected to learn around four to five languages to churn out basic program, learning a new language can be quite a task. If you want to use Corona SDK you need to have an internet connection as the publishing process is accomplished on Corona's servers. You need to upload your code as well as graphical assets to get the working file package. Though the world is going online remains connected during development seems like a challenge.

Unity:

For 3D game development this is the best platform you can go with. Unity has recently updated its engine for 2D capabilities. Offering unprecedented features and support, it is quick in adapting to new technologies and platforms. It supports Oculus rift.

The main USP of Unity is its wide device support. With its engine you can write one game and then use it to run on different platforms, including iPhones, Androids, Windows Phones, Macs, PCs, and Linux. You can even publish your game as a web application. Thus, you derive more from lesser efforts.

Two common coding languages are supported by Unity - C# and JavaScript. Boo is its custom scripting language. Beginners will find JavaScript easy and the good news is that it is supported by Unity.

Not only the powerful features are the reason behind its upper hand, it comes with excellent documentation as well as an active developer's forum. Plug-ins can be created to customize Unity as per the development needs. All this depicts that it truly is a platform worth investing in.

The above points clearly indicate the reasons for developers having a preference for Unity over Corona SDK and AndEngine. Unity is much easier, compared to other platforms, for developing games. It is an inevitable game development tool which offers powerful features with simplicity.

Ease of the use is its most promising feature. It always keeps on upgrading and providing improved functionalities to users. It surely is a rewarding platform.

To detect and remove virus from your PC, you must look for a copyrighted and updated version of antivirus support system.

Why Antivirus program support Is too Essential?
Before using an antivirus program, you need to check the facilities and after installation services provided by the company. For example, suppose you want to install a AVG antivirus program, first check AVG Billing Support system, AVG Customer Care, AVG password reset or recovery and AVG Technical Support system.

In case these facilities are not provided properly, you may suffer from certain losses and get the best outcome out of your antivirus. Sometimes, in case of unprotected and authorized antivirus system, your computer may stop to work properly. Norton, Macfee, Avast and all other antivirus support systems have professionals that will help you in troubleshoot & overcoming running problems of your PC. They are skilled and specialize in diagnosing & repairing the issues related to computer viruses.


What to Examine in Antivirus Support?

There are various features and services that you should check before adopting an antivirus support.
Some of them are:* Online Scanning:
A slow computer can be troublesome for you. Online scanning is the best alternative to resolve this problem and boost the performance of your PC. * Recovering an Infected System:
Remote Antivirus support techies can remove viruses and recover an infected system. This is a crucial fact as an O.S stops working or sometimes gets corrupted due to the presence of harmful virus programs.* Removing Virus Messages and Pop-Ups:
Unwanted & corrupted virus messages, pop-ups and mails can be irritating and also have an adverse effect on your computer. Only an authorized antivirus system and its supporting technicians can resolve this issue, very quickly and easily through Internet.

Clouds Can Discourage Threats During Business Operations

Businesses can no longer afford to be local in their operations as they need to go global to make an actual impact. This includes implementing solutions to handle risks.

Cloud packages can provide more secure solutions than internal systems. There are certain cloud supply chain solutions which are gaining in popularity.

For instance, there are networked supply chain solutions on the cloud that enable real-time collaboration between companies and their distributors around the clock.

Supplier networks are complex because there are many intricate issues that have to be dealt with. Traditional supply chain solutions like enterprise resource planning (ERP) were designed to make internal departments within an organization coordinate better. But they are in no position handle the external business procedures that suppliers have to contend with.

Supplier networks on the cloud provide more supply chain choices along with risk management abilities for companies.

Companies establish standards for quality for products that they supply to distributors in order to bag a contract. But these distributors subcontract a portion of the work to their distributors, causing quality path to be lost. When this happens, it creates risks to supply chain. To circumvent such issues, solutions have been produced on the cloud to keep tabs on suppliers at various levels. This cannot be achieved with internal solutions.

Organizations can lose trust of their customers and a lot of money if they have been found to be inadvertently doing business with an extremist outfit or a company with a dubious track record. Although the US and other developed economies publish 'watch lists' for companies wanting to enter into trade pacts, these lists are constantly changing. There are certain restricted list solutions on the cloud that monitor these changes and are integrated with many ERP systems to keep companies in the loop about black-listed organizations.

The cloud-based logistics solutions also help companies' bag smart shipping rates and allow them to use effectively intermodal logistics to mix various transporting methods to satisfy their customers.
There are cloud-based solutions also guaranteeing that goods that are being transported are safe and secure.


Increasing number of companies, therefore, now rely on the clouds of their logistics associates to track and make sure that their goods are safe in transit. Shipping containers are embedded with sensors to observe the temperatures within them for perishable goods. These sensors alert all the interested parties if the temperatures are not within standard limits. The sensors also monitor if anything untoward happens to the goods like attempts to steal or damage them.

5 Facts About Fiber Optic Cables

How well do you know fiber optic cables? If you don't have a lot of information about the cables here are a few facts that you need to know about them:

Optic Fiber Isn't Fragile

Although an optic fiber is made from glass and some of its areas require a lot of care, a complete fiber is designed such that it's able to withstand even the most rugged installations. For example, cat 5/5e/6/6A has a pulling tension of 25 pounds. There are other optics that are designed to withstand over 200 pounds of pulling tension.
Research studies have shown that a fiber optic can withstand higher pulling tension than copper. In addition to this, it's rated for larger temperature ranges and is immune to EM/RFI interference.

Fiber Is More Secure

Since information is carried within the cable, the information is more secure than in other cables; therefore, it's difficult to hack the information. While it's difficult to hack the information in the cables, it doesn't mean that they can't be hacked. This is because all you need to do is to have the network tap and physical access to the cable and you will be able to hack it.

It's Easy to Install The Cable

While the cable was difficult to install a few years ago, things have changed now as technologies have changed. If you want to install the cable you only need to contact installation professionals and the cable will be installed within a very short time.

The Cables Aren't Affected By Environmental Conditions

Since the fibers carry light, they aren't disturbed by changes in temperature, cold, rain or any other environmental condition. This is not the case with copper cables that are usually affected by environmental conditions. For example, when it's cold, the cables transmit data much faster than when it's hot.

They Support Wireless

The cables are heavily used by telecommunication companies to carry wireless telephone signals from the towers to the central network. The fibers are preferred by many companies due to their large bandwidth and long term compatibility with the network equipment.

Conclusion

These are some of the facts that you need to know about optic cables. When buying the units you should ensure that you buy them from authorized dealers. After buying them you should ensure that you install them professionally. If you don't have the skills you should hire an experienced professional to install them for you.

How to Save Time and Money With Trenchless Technology

If you need your underground sewage lines repaired or replaced, you may want to consider trenchless repair. Traditional methods of replacing sewer lines meant your lawn would be destroyed in the process of digging underground. With newer technology, only a small access point is created, and sophisticated equipment destroys the old pipe while putting a new pipe into place.
How It Works

First, the plumbing company should run a camera through the main sewer lines to diagnose the problem. They will explain your issue and how trenchless repair can be used to correct it. Two small holes are then dug at either end of the sewer line to be replaced. A cable is fed through from one opening to the other.

One end of the cable has a cone-shaped head attached that will destroy the existing pipe. Attached to the head is the new sewer pipe. When the cable is pulled through the old line, it breaks apart the old pipe and pulls the new one in behind it.

Sometimes, the existing pipe may be repaired with this method, creating a new, seamless pipe within the old one. This can be used to replace the entire line or simply in problem areas.
Advantages

The most obvious advantage of trenchless sewer line repair is that there is no major digging required, so it will minimally affect your yard. This saves you time and money, since you won't have to pay for excavation equipment, removal of the extra dirt, or a contractor to replace landscaping, walkways, or other areas of your yard.

In most cases, the new pipe that is installed is higher quality and will not be susceptible to the same problems with seams and joints failing like they do in traditional lines. Many companies will even offer a warranty or guarantee.
Disadvantages

There are not many disadvantages to trenchless methods. It may not be an option, however, if the line is in extremely poor condition. Since a line may break apart in a way that will not allow the new line to be placed, the only option might be to dig manually and replace everything underground.
While this method can save you time and money in the overall cost of your sewer line replacement, the actual service may cost a bit more depending on your particular issue. Again, without having to pay the extra costs of excavation, you will still probably come out ahead.

Having to repair or replace sewer lines is no small problem. Consider using a company experienced with trenchless technology so that the process for the repair will not do as much harm to your yard and surrounding areas.

How IT Service Management Is Like Dry Cleaning

Going to the dry cleaners is a bit like having the laundry elves visit your house. You drop off a white shirt with a coffee stain on the left side and when you come back the next day it looks brand new. And for the customer, that's all that matters. In between when you dropped off your shirt and when you picked it back up, however, those little elves were very busy getting you the results you wanted.
None of that really matters to you, though. You don't want to hear about how they had to sort the laundry, treat the stains, bag the garments or iron and starch the final product. All that matters to you is that your shirt is now clean.

When you're seeking a position as an IT professional, dry cleaning is surprisingly applicable. Just like the dry cleaning customer doesn't care how their shirt gets cleaned, businesses don't care how their computers and software are running. For them, IT service has two settings: meeting the expectations and not meeting the expectations. If it's not meeting the expectations, they want you to come solve it for them.

It's easy to become frustrated as an IT professional. Between the business users who really have skipped even the most basic troubleshooting of their own and the ones who think you should fix everything immediately, there's every reason for you to shut yourself in your office and bang your head off your desk for a few hours. But it's your job to fix their problem, not turn them into IT professionals themselves.

IT services covers a very broad range of actions. As an IT professional you probably have to keep up with patch management, vulnerability management, maintenance contracts, quality assurance and control, project management, development... the list goes on and on. But businesses don't hire IT professionals to explain everything, just like you don't want your dry cleaner to give you a lecture on stain removers every time you stop in. They just want you to get things up and running.

Businesses also tend to only concern themselves with the output of your service. A dry cleaner has to do regular maintenance on their equipment, buy cleaning supplies, pay their bills, and manage their water waste - none of which directly concerns you and your stained shirt. You don't care about any of that, you just want your shirt to be white again.

Similarly, an IT professional needs to be proactive to keep up with things that haven't yet caused obvious problems. A business might not notice you've upgraded their system, applied a new patch, closed a new security vulnerability, and renewed the maintenance contract. It's up to you as the IT professional to stay on top of those upgrade needs and explain how they're helping avoid major issues.

Dry cleaning and IT Services might not seem to have much in common, but you'll learn a lot if you approach your IT services position the same way you'd approach going to the dry cleaners. The business is only interested in the results, it's up to you to make sure the busy little elves get everything done.

Basic Network Management With SNMP

SNMP is a networking monitoring protocol that is incorporated within the TCP/IP suite of Internet protocols. It is used to monitor and manage devices remotely across a network and has 3 key components which are the managed devices, snmp agents and network management systems often just referred to as an NMS.

A managed device is an active network device such as a server, router, switch, workstation or in fact any device that is network capable. The managed devices are programmed to collect information from the host device, possible store that information and have the ability to forward that information to the Network Management Station.

An SNMP agent is a piece of software residing on a host network device which collects the programmed information and communicates that information in the form of SNMP Traps to the Network Management Station.

A Network Management Station is used to monitor and control SNMP host devices through a series of simple messages and also report that information to the network monitoring team in the form of some kind of alarm or report.

The NMS can run a number of application processes designed to gather information about known networked devices. This information can be status information such as a change in status of a Router interface or a Switch Port, device configuration changes or information relating to the performance of a managed device.

Often the software applications loaded onto Network Management Stations are proprietary, but do contain and operate with TCP/IP standards based SNMP. One good example of an SNMP application is HP Openview.

Devices that communicate with a NMS are often configured to be a member of a known community with a community string or password providing the community identity or authentication. Later versions of SNMP use a stronger form of Authentication and Encryption of SNMP messages. A NMS must be part of a community before it can receive or view messages or make configuration changes to the devices already part of the community.

The SNMP messages themselves contain the information from the managed device or instructions from the NMS in a data field and each message also contains the identity of the community to which the device belongs. The SNMP messages are sent across the network encapsulated within a UDP (User Datagram Protocol) packet, which in turn is encapsulated within an IP (Internet Protocol) packet.

The agent software installed on the host devices have what is known as a MIB (Management Information Base), which is a database containing a list of manageable objects on the device. When a device needs to inform the Network Management Station about a configuration or status change, it sends a message known as a TRAP to the community NMS informing of the change.
The NMS has a number of message types it can use to interrogate or make changes to configuration on the managed devices and these are:

GET - Is used to ask the managed device for certain information about a managed object on the device. It could be a request for status of a router interface or the amount of disk space on the device hard disk drive.

GET-NEXT - Used to request the value of the next managed object in the device MIB.

SET - This is where the NMS can actually change the value of a managed object's variable, providing the object allows READ / WRITE access. If READ Only then this will not be possible.

The Management Information Base on the managed device will contain hierarchically organized information which are identified by what are known as object identifiers, which are universally known.

Cloud Computing A Basic Definition

We all keep hearing the term "Cloud Services" or "Cloud Computing, but what is it referring to? The Internet has for many years been referred to as the Cloud, with TCP/IP being the suite of protocols used to make the Internet function. Data goes into the cloud and is delivered to another area of the World determined by a unique destination IP Address.

Cloud computing is constantly evolving, but is essentially a network infrastructure with servers, platforms, applications and storage facilities. A network of shared resources that can be quickly provisioned in response to customer demand. If you need computer storage space for a day, a week or a year, there are many providers who will offer that service for a competitive price. Cloud Computing allows us to have an On-Demand service from anywhere in the World, provided we have an Internet connection.

There are quite a few service models evolving, but the fundamental service models are:
1. IaaS - Infrastructure as a Service
2. PaaS - Platform as a Service
3. SaaS - Software as a Service

Software as a Service (SaaS) allows subscribers to use the Cloud Provider's software applications running on their infrastructure from a subscribers terminals connected to the Internet. It often requires the use of Thin Client software running through a local Web Browser application. The subscriber merely uses the provider's network with all its complexity to carry out the required tasks.
Platform as a Service (PaaS) allows the subscriber to use computer or server platforms to host and run their own applications. The provider controls the use of the infrastructure, platforms and services. The subscriber controls the use of their own applications and the environment they run in.
Infrastructure as a Service (IaaS) provides the subscriber with an infrastructure over which to conduct their network operations. The subscriber is given control of specific infrastructure such as servers, operating systems, storage devices and security devices to name a few.

The biggest use of the Cloud is probably the ability to store personal or company information and the ability to access that information.

Although the biggest area of this type of computing is in the Public Domain, where providers offer these services to the general public, either private individuals or companies, there are other models for the use of Cloud Computing.

Up to now we have eluded to the Public cloud. but other network types include:
Private Cloud - This is a network that is operated on behalf of a company or organisation. In some cases it may be managed or hosted by a third party organisation, but is still solely for the use of a single organisation.

Community Cloud - As it's name suggests, the network resources are shared by a number of organisations or businesses that have a common purpose. Again this type of network can be managed by the organisations themselves or by a third party organisation.
Hybrid Cloud - This can be a complex network with elements of public, private and community cloud networks that run common technologies.

There have been, and still are security concerns over this type of computing. We all know that the Internet can be a dangerous place with more vulnerabilities being uncovered almost daily. Company and private networks are open to attacks for all sorts of reasons, which result in malicious damage or compromise of data. A provider that hosts services such as storage for many thousands of organisations or companies is almost certainly identified as a more important target to those that might want to breach any security. A breach would yield access to much more data and therefore the damage could be much more severe. I suppose the question to ask is " do you trust your provider to keep your data safe"?

There is no doubt about it that Cloud Computing is here to stay and will only continue to grow, but it is up to individual organisations to weigh up the advantages and assess the security risks before accessing these services.

Bluetooth - The New Mode of Wireless

You are living in the 21st century where everything is going through a revolution in the hands of technology. One of the successful innovations of technology was the introduction of the serial Bluetooth. It is a wireless network that allows various devices made from different manufacturers to connect within a 30 feet range of area.

Advantages of Bluetooth

Wireless - With the invention of Bluetooth, it is time to say goodbye to all the wires and cables. Now, you needn't worry about carrying connection cables. You can easily travel with your laptops or various wireless devices and avail the benefits of Bluetooth.

Automatic - You don't have to do much to get Bluetooth connections near you. It is automatic and connects all the available devices in your range of 30 feet.

User friendly - It is simple to use and one can also set up connections between different devices with ease. And guess what? It is free and doesn't require any charges to be paid to service providers.
Inexpensive - The implementations of this technology is quite inexpensive that results in minimum cost for the companies. The company therefore, passes on the cost effective Bluetooth on to us.

Low energy - As Bluetooth involves the use of very less power signals, little amount of energy gets consumed. This helps in using up less battery or power. This is best for a cell phone as the battery hardly gets drained out.

Uniform Protocol - The wireless protocol is standardized and compatible with various devices. It guarantees connection between different devices even if they are of different models.
Low interference - Bluetooth with the help of the frequency hopping technique and minimum wireless power signals can overcome interference of other wireless devices.

Instantaneous PAN - Within a particular range of area, a Bluetooth can function and link up to around seven devices. This network that gets created can be termed as a Personal Area Network or piconet. Various piconets can also be installed within the same room.

Advancement - Every technology gets updated and upgraded with time. There are new versions offering new advantages that should be updated.

Universal - The Bluetooth technology is gaining popularity world-wide. It has become a standard wireless medium universally and one can count on the improvement. With a gradual increase in devices choosing to use the Bluetooth technology, different manufacturers will start making their products compatible.

Applications of Bluetooth

The first and foremost application can be a headset that is provided to a cell phone. This headset is wireless and is attached to the ear. A person can take calls and interact without even touching the cell phone. The cell phone can be kept anywhere in the body or the bag carried. The technology doesn't let radiations to affect the cerebral area and therefore eliminates any such radiations.
Data transfers become easy when Bluetooth got introduced in the PCs and laptops. Latest information gets synchronized easily in a mere fraction of time.

Recently, wireless mouse and keyboards have been introduced for easy usage of the PCs.
One can connect a printer to a laptop via Bluetooth that helps in making fast printing documents without any hassle.

Cars and music systems nowadays have the Bluetooth function enabled.
Bluetooth is one of those wireless technologies that has eliminated and removed the complete usage of wired technology. As more and more devices are coming up, Bluetooth is becoming more widespread
