why two people get 2 results while preforming a task?

As humans we are not the same. we have our strength and weaknesses. my strength is different from you and your strength is different form mine. so we become two different entities not the same. Strength can be physical the ability to lift things, mental ability to grasp and understand things or social to ability to communicate with people and convince them or make them work for you. There are many strength people have and if I scale each of them as set of 1 to 100 they will fall in to all the range. some are naturally better at something’s while others are not. you may see marketing executives selling things they are not people with degrees but preform their task well. they are vary talkative and can sell anything to anyone. It is an ability a group of people possess. Ability’s like this cannot be learn at class rooms they are practical in nature and practice is the only way of getting perfect. so even you do your masters on marketing you may not be as good as them, if you does not possess the right abilities. It is the thing that makes who we are. what makes us unique. so if you give a same task to two individuals with same education background the way they perform the task will be defendant to each other even they are with same education background. one will do it better than the other. For some there will be no clue what so ever to some task, while others do it easily it is the abilities that make them do it. the one that has more suited abilities to do that task perform well while one that lac it do poorly

if you are a labor you will require more of physical strength but less mental strength since all your task belong to work with lifting things. If you are an engineer like software engineer you will require more of mental strength since task you handle is more of thinking and understanding whats going on, analyzing problems and also you must be a quick learner to learn new things which all comes under mental strength, if you are a marketing executive you need lot of social strength you should be able to convince people of products that you sell so they will buy it. if you are a manager you need lot of social strength since you need to make your employee do what you need and fair amount of mental strength since some of your task require thinking. analyzing situations and giving solutions.

That is why when selecting candidates for your company you do practical base analysis of their abilities to find out how well they will perform in their duties because education is not a measurement of performance it is rather a measurement of knowledge and knowledge alone cannot do tasks well.

so most of the time the person you recruit is not some one well educated, but some one possess right ability to that job. since you can easily give courses like CIMA or any marketing or engineering to a recruited person so they will be educated and will preform even better. but if recruited a person with just education an no talents you cannot teach that person talents and he will not preform well so most of the companies when they see a talented person they give him courses and educate him on that aria and give necessary promotions so that person will be an asset to the company. if you have done some sport like cricket or basket ball then you are a good team player. so you will know how to work within a team and not make problems with other team members. if you have win all island essay competitions you most likely are a creative person you have creativity. if you are an chess player and has win competitions you are statistic person who can think and most suitable for that tasks so they will choose you accordingly.

unfortunately the only organization that held back of this process is the government sector since they believe every person is equal and education makes them better so you only need bunch of paper qualification to their jobs just do your masters and PhDs and apply, you need not have any talents. they will recruit you and for work well since you are well educated they will buy what ever the lies you tell them.

What is AI (Artificial Intelligence)?

Giving the ability for computer to think is called AI, it is decision making based on data you have. If you have enough data you can tell a computer to make some decision as you would, it is allowing computer to think like a human or mimic how humans think.

The story goes way back when once in a meeting of experts one young man suggest what if we let computer’s think. everyone laugh at this idea of course, then the man explained what is thinking we try something out if it works we remember it and every time we see it happening we try that since it works and if we fails we do not try that any more

This concept let to the development of artificial intelligence software of course they are software that mimic or do the behavior like humans search through their database to see if any pattern fit in the scenario if it does it try it out if not it does not

Surprisingly the game you know well about "the chess", computer plays the same way, it knows all the rules and it plays with you like a noob and try to win. Every time it wins the moves are remembered and   next time it try to match that moves with you and try to find a wining position. When you do this or play chess with computer for lot of times it eventually will get better and beat you, and you will no longer will able to win.

AI in real world has taken many steps now facial recognition system, text to speech, and speech to text and there are many more. most of these system works on algorithm that given to them the use that to find out the task. there are other things like neural networks and genetic algorithm which you can train to do a task or set a goal and let the computer find a solution. neural network is model after neuron function of the brain. it makes artificial neurons and try to achieve a same functionality as them using some mathematical formulas so it will mimic the behavior of the brain but to complete  modeling a human brain is yet to be achieved since it takes lot of them and research current technology could not yet achieve it.

So that is how the AI was made, it learn by experience, it is mimicking the behavior of humans and try to do what is right?

My Fun Games

Some Games I have developed for your entertainment
My Pet Dragon

Simple AI
A simple AI try to query it with what,who, how many, can,do, like "what is cat", "how many legs cat has","can cat fly","who can fly","do cat eat". if you need to teach the AI some thing type learn and you will put it in learning mode and then type like "dog can run", or "birds can fly" teach it what ever and use it to query it, if you want to remove any thing from the knowledge base type "remove" and then type what you want to remove eg. "remove rat can fly" this program has ability to answer if it is in a chain that is if Mammal eat food you do not have to tell dog eat food you only have to tell it that dog is a mammal and it will search in chain and say since dog is a mammal and mammal eat food then dog eat food too

Tank Battle

Logic Bench
a logic bench that you can build logic circuits just click on logic gate and then drag it to get your logic gate. right click the logic gate choose in for gate where the data will go in and select the gate that you need to connect to it and select out then choose connect 1 or connect 2 to connect it to one of the connections. and do this to all your gates and you will complete the logic circus.

a programme that let you run dos command remotely set up your client and server when ask for firewall bypass say ok and you are set up to run dos command on your pc remotely

Movies How its Done?

with evaluation of computers, the movies that run on theater came to them as that can be stored in a hard disk. Hows this possible? What makes a movie run on computer. The  truth is movies run as same way as theater. theaters use sequence of images to run one after another so it will give an illusion as continuous thing. See our eye can only process data coming from 1/10 of a second, so anything less you will not find as 2 but a continuation of first i.e. if some pictures changes in 1/5 of a second you will see that it changes, but if it change in 1/24 the of a second you will see as continue animation. So we can trick the eye to believe it is real this is because fastest speed of our neuron take 1/10 of time to communicate so to send an image from eye to brain and process it will take more than 1/10 seconds of time and any thing coming between this to eye, we will not see and when second image comes and if it is moved slightly the brain will fill the gaps and let us see as it is moving or animated.

so if we show our brain image in every 1/24 th of a second we will see it as animated. So in computer where is the images comes from. As you know we can store images as series of pixels and can have array of these series of pixels stack one after the other. giving us a series of images one after the other. and player is able to call them in a given rate and draw them to display like 1/24 th of a second so we will see a series of images in front of us and our brain will think it is continues and let us see the movie.

it will take a lot of space to keep a movie in row form, since it is a series of image so compression is done. some of the images are removed and images also get compressed like you know in jpg or gif so it will reduce the size of the movie dramatically. With this quality also degraded but we get to see a nice movie.

for instance a movie on 1 hour will take 60X60 seconds and that is 60X60X24 frames. If it runs 24 images for seconds (which is called frame rate) and if the size of the image, that is width and height of the movie is 800X600 i.e. 800 pixels wide and 600 pixels in hight, then it will take 800X600X3 number of bytes since each pixel take 3 bytes to represent the colors RGB one for red one for Green one for Blue so to store whole movie it will take 60X60X24X800X600X3 bytes i.e. 124416000000 bytes or 115GB which is not the best to store in hard disks so it is compressed to something like 1.5 GB to save space. by methods like MPEG4

Enable and Configure NAT

Applies To: Windows Server 2008 R2

Network address translation (NAT) allows you to share a connection to the public Internet through a single interface with a single public IP address. The computers on the private network use private, non-routable addresses. NAT maps the private addresses to the public address.

Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure.

To enable network address translation addressing

1. In the RRAS MMC snap-in, expand Your Server Name. If you are using Server Manager, expand Routing and Remote Access.
2. Expand IPv4, right-click NAT, and then click Properties.
3. If you do not have a DHCP server on the private network, then you can use the RRAS server to respond to DHCP address requests. To do this, on the Address Assignmenttab, select the Automatically assign IP addresses by using the DHCP allocator check box.
4. To allocate addresses to clients on the private network by acting as a DHCP server, in IP address and Mask, configure a subnet address from which the addresses are assigned. For example, if you enter 192.168.0.0 and a subnet mask of 255.255.255.0, then the RRAS server responds to DHCP requests with address assignments from 192.168.0.1 through 192.168.0.254.
5. (Optional) To exclude addresses in the configured network range from being assigned to DHCP clients on the private network, click Exclude, click Add, and then configure the addresses.
6. To add the public interface to the NAT configuration, right-click NAT, and then click New Interface. Select the interface connected to the public network, and then clickOK.
7. On the NAT tab, click Public interface connected to the Internet and Enable NAT on this interface, and then click OK.
8. If you want to add additional public addresses assigned to this interface or configure service and port mappings to computers on the private network, see IPv4 - NAT - Interface - Properties Page.
9. To add the private interface to the NAT configuration, right-click NAT, and then click New Interface. Select the interface connected to the private network, and then clickOK.
10. On the NAT tab, click Private interface connected to private network, and then click OK.

Logical Thinking for Programming

Operating system

Early days when computer emerge there was programmers who write software to it. most of them were in low level languages like machine language and they were machine specific i.e. each machines software were written to it separately. Every machine use different sets of hardware and they have to handle differently so single program could not work on every machine programmers have to be written each machine separately.

These programs consist how to handle details like hardware how to send your report to printer i.e. instruction on printer how to print and sound instruction to play sound and instruction on display so they can be displayed correctly multi-tasking is a dream  they never even thought of and computers are assign single task. With the change of the hardware the software have to be change to adapt the needs of it.
Then people began to develop common platform to a compute that will manage hardware (takes care of how to handle and send instructions) and also resource management which make image of operating systems. The other software could be run on these systems depending on them so they need not to worry about the hardware or resource management tie OS did it for them. But still the OS depend on hardware and each machine have to be coded OS separately

With this things like DOS (Disk Operating system emerge) and a smart guy call bill gate had the chance to get hold of one of this he buy the system with the cording from the developer and did something miraculous, he separate the operation of hardware form the operating system so you have need not to code entire OS but the parts specifically handle that hardware which you may know now as drivers with this OS could run on multiple computers with minimum change OS are built to multi task, that is more than one process could run on single machine this is achieved by dividing time across different processes a few millisecond on process 1 and then few on process 2 then again few on 1 so on. It also handle resource management i.e. how they are shared among processes and also have mechanisms like deadlocks prevention that handle the conflicts of the resource with process. There is file manager that manage files you do not need to access hard disk directly OS do it for you so you only have to tell OS what you have to do (not how you need to do it) and OS will do it for you.

With the CLI (Command line Interface OS) we have come very far and now we have GUI(Graphical User Interface) Operating systems and many more facilities that you ever need.
