Running Dual Monitors

At the present time most computer monitors are running a minimum of 256 colors and there are a very limited number of monochrome monitors left in operation. The few remaining monochrome monitors are basically used with computers that run simple databases in some financial institutions or similar uses. Just about everything else is currently using color monitors.

The next step in computer displays is the use of running dual monitors. This comes in really handy for both the private sector as well as business applications. Running dual displays doubles your visual tabletop making your multitasking much easier to work with.

A dual monitor system can be set up different ways. You can set them up to act as a extra wide view, so you can drag and drop work between the two displays. They can also be set up to show identical views (perfect for business applications where a second party needs to see the screen), or they can be set up independent of each other.

Many cab companies and courier services use the dual computer monitors because there is always a active screen that they need to keep up on the monitor at all times. In a situation as this, the second monitor would be for that purpose. In these situations the second monitor may be displaying the availability of units rolling around a metropolitan area, or the second monitor could be showing ‘GPS’ activity of units in the field while monitor number one does the dispatching work. These are not the limitations of running dual monitors, but rather just a couple of examples.

Personal uses of dual monitors are just as beneficial. Running two monitors on a personal computer gives the computer owner the ability to do multi-tasking without closing or minimizing a entire window. Some examples of these uses on a personal computer are simple. You may be writing a letter on monitor number one while watching a DVD on monitor number two.

I personally use dual monitors on my computer because of a number of reasons, mostly because of the graphics software that I use in my photography hobby, other times I watch German television stations on monitor number two while surfing the web or reading emails on monitor number one.

One might ask, “is it hard to setup dual monitors on a computer?”. Actually, it isn’t hard at all. If your computer doesn’t offer two outlets for plugging in two monitors, the upgrade is pretty simple for you or a shop to do.

First you have to purchase a display card that will give you the dual monitor capability. These will in most cases be available as a video graphics card to go into the green slot of your computers mother board. If your computer is currently running a PCI or ISA display card, … you will have to remove that card before installing the new card to avoid computer system conflicts in the device manager of your operating system.

If your computer is using a ‘onboard’ display adapter, … the onboard display device will automatically become null and void as you install the software for the new card you are installing, because the drivers for the new card will show up as a upgrade with a more current date.

Once the card and its software are installed, go into the software for the card you bought and setup the way you want the displays to appear.

There are a great deal of manufacturers out there that make display cards for running dual monitors, and they can differ in price greatly. Prices can range anywhere from $99.00 up to a couple thousand dollars. I installed my card that was manufactured by ATI. It is the ATI Fire GL V7300 Graphics Adapter which gives a maximum resolution of 3840 by 2400. This card can be used by Linux systems as well as Windows systems and the card costs about $1,348.00 depending on where you buy it.

Your local computer store may offer more affordable cards that sell for under $500.00. I bought mine on the theory ‘you get what you pay for’. But that’s me, … someone else could be very happy with a standard card under $500.00.

Regardless of the price range you decide to go with, … a important fact is, buy one that offers a lot of it’s own onboard memory. The more memory it has, the better. The last thing you would want to experience is a slow machine because you are doing demanding things that requires video memory, finding out you bought a card with small memory and now its drawing the balance of the memory it needs from your system ram. Do it right and make it worth your while. Get a card with a lot of memory, you will be very happy with it.

I’ve already been asked if it was possible to run more than two monitors on one computer. Yes it is. However for personal computers and most businesses, this wouldn’t be practical. Only a few mandatory needs are currently out there for this technology. A couple of examples being, people working in the New York Stock Exchange (for watching numerous stock activities at once) or some major 911 dispatch centers across America in large metropolitan area’s, for monitoring and dispatching police, fire, and paramedics.

What’s more, … to setup a computer with four or more monitors could cost thousands of dollars, and usually is run with some custom software that costs just as much.

Running dual monitors is something that absolutely anyone can do and benefit from it. As I mentioned earlier, … the price range is pretty wide. You can do it, … just pick your price.

Antivir64

Antivir64…not What it Seems

Antivir64 is one of many rogue security tool programs a person may encounter on the Internet. Corrupt security programs are the latest in malware technology, and are clearly nothing but malicious. They pretend to be actual antispyware or antivirus tools, but actually provide you with a malware infection and try to scam you out of your money. They can actually lead into a full blown identity theft, and leave you nothing but broke and with a malicious program.

Malicious antimalware programs will often lurk in the more seedy parts of the internet. They also will tend to have a counterfeit antispyware or antivirus site. Although efforts are underway to shut down infected websites, this process just isn’t fast enough to catch them all. Most of the time, the infected websites are pornographically or gambling oriented, when they’re not being truly deceptive with the infected antimalware sites. Occasionally an infection from a seedy site will redirect a user to the infected security tool sites.

The other primary means of transmission of these programs is much harder to track and prevent. A user can also get infected from peer to peer (P2P) file sharing and downloading pirated software. These may also redirect you to a bogus antimalware home page. Aside from being illegal, which has its own risks, the danger of infection is extremely high from these practices. Ultimately, it’s really just not worth it.

Unfortunately, aside from having a good antispyware program, there is no way to preemptively know that a website is infected. This is why the false security tool pages exist. If you don’t have a good program already, you’re probably looking for one. You may also want to test the effectiveness of their software, so you may want to click their “free online scan” or “free trial version” button. This will automatically lead to an infection. The presence of these buttons is unfortunately no sign of an infected site. Many legitimate security tool websites have these buttons as well.

If you get infected, you’re in for a nightmare. First, they’ll never tell you that you’re not infected. They will count all your temporary files and say that they’re infected files. Then you will be offered the full version for a relatively high price. Actually, the price could be all the money left in your credit card or bank account. Next they will get into some hard selling. There is a button to accept the offer, and there is one to turn it down. However, if you turn down the software, they will never say, “Okay, bye then.” The window will immediately pop back up and won’t let you do anything else with your browser.

Naturally, you don’t want to buy their low-end program. The most effective thing it will do is download more spyware on your computer anyway. You still can get out of this situation by turning off your PC. Then it’s time to go and get a real security tool and clean house.

Agents for Telecommunications

Today’s telecommunications networks are a delicate blend of clients and servers that together offer virtually endless possibilities when it comes to services and applications. For every new client developed, there seems to be a score more on the way — from mobile handsets, PDAs, terminals, telephones, video phones, IP set-top-boxes, and so on.

There are essentially two types of servers that connect between clients on large networks: Proxy servers and Back-to-Back User Agent (B2BUA) servers. The more prevalent Proxy servers feature predictable behavior — simply connecting between clients. Effectively, B2BUA servers are much stronger and intelligent entities that perform actions which Proxy servers cannot. Moreover, B2BUA servers provide a flexible solution for a wide range of applications and services and are becoming the primary engine for more and more SIP servers in NGN and IMS networks.

The difference between Proxy servers and B2BUA servers is sometimes not fully understood. In this article, we will explore what makes B2BUA servers such an appealing alternative to standard Proxy servers. Better understanding of B2BUA servers can help managers understand the value, and the tradeoffs, of choosing a B2BUA server, as well as the frameworks needed to develop a wide range of SIP applications and SIP services using it.

Figure 1 - Architectural difference between Proxy servers and B2BUA servers

B2BUA Server Defined
B2BUA servers are used to provide value added features for point-to-point calls and manage multi-point calls. The power behind a B2BUA server is derived mostly from the fact that it has a very generic definition, which gives it almost unlimited power. However, this same characteristic is the root of the controversy surrounding it.

IETF standard (RFC 3261) defines a back-to-back user agent as “a logical entity that receives a request and processes it as a user agent server (UAS). In order to determine how the request should be answered, it acts as a user agent client (UAC) and generates requests. Unlike a Proxy server, it maintains a dialogue state and must participate in all requests sent on the dialogues it has established.”

B2BUA servers have capabilities that far exceed those of other types of SIP servers, and answer the need for developing sophisticated value added SIP applications that cannot be implemented as Proxy applications.

Some of these capabilities, which are unique to B2BUA servers, are outlined below:

3rd Party Call Control (3PCC) Features
3rd Party Call Control (3PCC) is the ability of an entity (usually a controller) to set up and manage communication between two or more parties. 3PCC is often used for operator services and conferencing.

3PCC actions are important capabilities, exclusive to B2BUA servers since “passive” non call-stateful elements, such as Proxy servers, cannot initiate these types of activities. Some examples of 3PCC services are online billing, QoS, resource prioritization, call transfer, click-to-dial, mid-call announcement and more.

3PCC actions can be initiated automatically by B2BUA server applications, like disconnecting a call following credit expiration in an online-billing system. Or they can be initiated by remote administrative control (OSS), e.g. invite parties to a multi-point conferencing session.

Figure 2 - Schematic outline of B2BUA server offering 3PCC functionality

Inter-working Function (IWF) for Interoperability

SIP was designed as a highly flexible and extendible protocol. The very strength of this flexibility is also an inherent weakness, since the vast array of client types in the market still need to connect.

B2BUA Inter-working Functions (IWF) defines a wide range of powerful SIP servers that connect SIP clients that “speak” in different protocol dialects, or support different capabilities. This Inter-working function is very important in enabling connectivity between clients with different capabilities and/or protocol dialects. Or even between clients and networks – where the B2BUA server actually acts as an access device.

Examples of what IWF can do include:

• Connecting SIP clients to IMS networks by adding and removing IMS SIP protocol extensions (AKA P-Headers) that are essential for connecting to the IMS network
• Connecting clients with different Session Timers settings
• Connecting clients with different media capabilities and with distinct Session Description Protocol (SDP) messages by relaying between the two types of control sessions
• Connecting to different types of networks (e.g. IPv4, IPv6) and support for different transport types, such as TCP/UDP/SCTP/TLS

Figure 3 - Schematic outline of a B2BUA Inter-Working Function

Multi-point Call Management

B2BUA servers an also implement multi-point call scenarios where multiple CPE devices connect to the B2BUA, and the B2BUA provides services to all CPE.

Due to these unique capabilities, B2BUA servers are widely used in the communications industry. A few examples are listed below:

• Online-billing/prepaid functions
• Servers supporting Resource Prioritization (RP) and/or Quality of Service (QoS) features
• Multi Point Conferencing servers
• IVR servers
• PBX Applications and Softswitches
• Application Layer Gateways (ALG)
• FW/NAT Traversal applications
• Privacy servers
• 3rd-Party Call Control Applications (3PCC)
• Service Creation Environment (SCE) runtime engines
• Session Boarder Controller (SBC)
• IMS S-CSCF, P-CSCF, I-CSCF
• SIP Inter-work Function (IWF) Gateway
• Security Gateway (SEG)
• Voice Call Continuity (VCC) servers

In addition, B2BUA servers play an important role in emerging IMS networks. Recent releases of 3GPP IMS specifications (3GPP TS 24.229 V8.0.0) indicate that an increasing number of IMS network element servers, such as P-CSCF, IBCF,SBC etc., are B2BUA servers. The reason for this is that value added services are usually session stateful, and feature capabilities that go beyond basic call proxying. Applications written on top of B2BUA Application servers fulfill several roles, such as SIP User Agents, SIP Proxy servers and SIP Registrars.

B2BUA Server Challenges

B2BUA application developers face many challenges, such as achieving rapid time-to-market, conformance and interoperability, offering customization for proprietary services and support for High Availability (HA) and redundancy. A comprehensive B2BUA framework can help developers overcome these challenges.

A solid B2BUA framework should have modular application building block architecture for increased flexibility, abstraction and short delivery time. Traditional architecture, which features a single configurable state machine, is not flexible enough. Also, a B2BUA framework should facilitate developing B2BUA applications by flexibly linking “pluggable” high-level Modular Application Building Blocks (MABB). Developers should have the ability to combine these MABBs and they should be designed in a way that allows developers to further customize their behavior if needed. This type of architecture complies with contemporary Service Oriented Architecture (SOA) concepts, and is suitable for powering flexible business communication platforms. This modular architecture can save months of work. With a set of MABBs in hand, developing the application is a matter of combining existing MABBs to produce the required business logic. In addition, this architecture enhances efficiency; development of new MABBs can be done concurrently.

A B2BUA framework should facilitate developing applications that fully conform to standards and are interoperable; without restricting developers from customizing protocol behavior for special cases. Moreover, it should conform for non-standard implementations, as well as to mediate between two versions of the same standard. This type of framework allows developers to focus on their proprietary application with the confidence that their final application will be fully interoperable.

And finally, a B2BUA framework should provide the ability to configure, amend and replace application building blocks to create proprietary features. With this ability, developers can maximize existing code – significantly reducing development time, shortening testing cycles, and reducing overall time-to-market.

Figure 4 - Traditional architecture of a B2BUA framework

RADVISION’s B2BUA Application Framework http://www.radvision.com/Products/Developer/SIPServer delivers these capabilities and more. The B2BUA Application Framework module is a part of the RADVISION SIP server Platform, a software framework that offers the essential building blocks for the development of a wide variety of high performance SIP and IMS servers. The rich set of components and modules can be flexibly combined to match customers’ requirements for developing SIP servers that offer both standard and advanced SIP services.

Applications written on top of RADVISION’s B2BUA framework are developed by combining customizable modular application building blocks. This is effectively large chunks of functionality that can be strung together to form ad-hoc applications, enabling developers to focus on the high-level business logic and use building blocks that hide low-level details.

As one of the most popular IM applications, Yahoo! Messenger was the first large consumer player that adopted B2B UA. Yahoo! Messenger combined its backend scalable platform with RADVISION’s B2B UA to serve millions of monthly unique messaging users around the world. Yahoo selected RADVISION’s B2BUA due to its robust performance and scalability features.

Figure 5 - The architecture of RADVISION B2BUA Application Framework


RADVISION also offers automatic High Availability (HA) and Redundancy support. The B2BUA framework automatically replicates the run-time state of the different Services and B2BUA framework core. In the event of a server outage, a redundant server takes over seamlessly and provides uninterrupted service continuity.

B2BUA framework benefits in a nutshell

• Significantly reduces time to market developing proprietary B2B applications and services.
• Allows adding advanced services easily to retain competitive advantage and evolve to meet growing customer demands.
• Focuses on the business logic and hides low level operator communication intricacies.
• Delivers off-the-shelf conformance and interoperability.
• Enables rapid development of applications that can interoperate with different vendors.
• Enables adding high-availability features easily.

Keyword Mastery & Search Engine

Keyword Research has become an integral part of starting up your own business or growing your business (exponentially). Search engine marketing is here to stay for the long term, hence finding customers through keyword research should also be an integral part of your marketing.

Earlier, all you needed to do was to enter the description of your business in the title & meta tags and you were done with optimizing your web-site. Things have changed! And hence this article...

How does Search Engine Optimization (SEO) relate to keywords?

SEO is the process of increasing the number of visitors to your web-page by the careful and deliberate use of targeted keywords and their specific placements designed to get the page to show up on the top listing for such keywords. (SEO also includes other strategies not discussed here.)

TIP: Keyword Research is very useful to you when you decide to start a pay-per-click campaign to drive visitors to your website or increase revenue using adsense.

Here are the seven simple steps to keyword mastery that will cause your page to be indexed correctly by Search Engines and your link to be displayed at the very top on the search results page.

Step 1) Start with the most common words you use to describe your business(or your niche, if you operate in one). If you are in the automobile service business, you may have the following: Car Repair , Body Shop, Car Repair, New tires with car repair, Wax and Shine etc. If you actually have a niche business such as Jaguar Service And Repairs, then it becomes even more easier.

Step 2) Call your friend. Ask him how he would try to find your widget on a search engine if he lost your phone number and he wanted to look you up on the Internet. What if he forgot the name of your establishment? What if ....

Your perception of how people see you may be different from your customers' perception of you. Add these new words to the list.

Repeat this as many times as you can with different people.

Step 3) Find other words related to your original list. such as names of the brands. Lexus Repair, Lexus spare-parts, Honda kit, etc.

Mix and match keywords with your original list to find even more keywords.

Step 4) Go to google and run a search for your widget. See what keywords bring up your competition and what words do not. Add them to your list .

Step 5) Add plurals and common mis-spellings too.


Step 6) Figure out as to how often people search using each of the phrases you have identified in your list. You can use the google adwords tool for this purpose.

TIP: Use adwords tool to see how many people have searched for each of your phrases in the recent past. https://adwords.google.com . This also suggest keywords you might want to use.

Step 7) Make sure your keywords are placed in the following locations on you web page: Page Title, Meta Keywords, Meta Description, Header Tags, Alternate Description for images, First Paragraph on the page, strong Tags, Em tags, Ordered and unordered lists, Anchor Tags, File names, Folder Names, Footer Tags, Any URLs and links in your pages.

Should I use many keywords in the same page?

Yes. Use as many keywords as it makes sense. Don't overdo it. If your content becomes just a keyword trash-bin, users will start skipping over it and the search engines will catch on pretty fast. So avoid using too many keywords where it does not make sense. It's best if you have multiple pages offering up different keywords.

One caveat. You need to be aware of 'Keyword density'. Sometimes, if your usage of keywords is too high, and it looks like you have placed too many keywords, the search engine may not give you the best ranking. "Sprinkling" is the key-word when it comes to using them on each page.

You should also be aware of negative keywords. These are keywords you need to use in your PPC(Pay-per-Click) text so as to make sure that people do not click your link expecting to get freebies.

e.g. If you said : "Self Clearning Widgets- $500 and up", you keep out the people who are looking for cheaper stuff.

Are phrases better than individual words?

Depends! If your customer is searching for self-cleaning widget, then you should use self-cleaning widget. If your customer is searching for just widget, and auto clean, you should use these words separately.

How often do I have to check my keywords?

As often as you can. Your customers react to various influences around them and search for different terms at different times. To be able to remain on top with a good ranking you need to keep on top of your keywords. Sometimes they react to an offer made by a competition and start searching for similar offers.

I know. You are saying:"But I don't have that much time to devote to just keyword research." That brings us to the next question.

Do I have to do it all by myself?

I have had many websites in the past few years. In the beginning I did everything manually the old fashioned way.

Lately I've found a few tools that help make life easier for me, though you could do it all by yourselves if you had the time and the tenacity(which I sorely lack). I suggest you find yourselves a tool to do the work for you.

I use Keyword Elite now, though I've used WordTracker in the past.

Pick 1: Keyword Elite tool : If you really plan to take your business to the next level, this is a great tool. From generating your own keyword lists, to analyzing pay-per-click listings, to studying your competition, this one accomplishes quite a bit. This tool works with Google, Yahoo,MSN, Ask etc. It will save you tons of hours of wasted time and effort. Also, I like the fact that it is multi-threaded(lots of more power.)

WebSite: www.elitekeyword.net

Pick 2 : WordTracker: Offers a free, 'lite' version, as well as a paid version. Features include an online management system for different keyword projects, searching for often misspelled words, a system to calculate your best keywords, and much more. WebSite:Wordtracker.com/FreeWordtracker

Pick 3 : WebCEO :From a free version to a $389/- version this company has various options available. For small business owners, the $199/- version would be suitable.Go for the $389/- version if you have multiple web-sites running and your business model is solely online. Web Site: www.webceo.com

What next ?

Use keyword research to identify the most likely phrases for your business.

Master keyword research just like I outlined in this article and create a massive list of targeted keywords.

Make a list of the 5 most promising keyword phrases.

Head over to your favorite domain listing / hosting company (eg. www.GoDaddy.com) and see if you can buy that phrase in the .com domain.eg. Self-cleaning-Widgets.com

Point your existing website to this url. If you don't have an existing web-site, create your new website using all the keywords you identified.

Submit your site to the search engines.

Happy hunting!
