Best Features Of A Digital Camera

Best Features Of A Digital CameraIt takes one around and through the digital camera so one knows how it works and what its features are used for as there are hundreds of links to the best sources and products so you can learn even more. There is a great variety in cameras for example the one for the beginners has E-TTL II for stable flash exposures and improved White balance compensation for the clarity of the picture. To store these cameras there is a specially designed carry case with internal pockets large enough to hold money or credit cards.Zoom cameras:Zoom cameras are used for a better picture and better efficiency by moving the sensor itself to give a better quality of picture. There is an image processing technology, which gives users images as beautiful as those they see with their own eyes and this makes the camera a special one. Some cameras can be described in a sentence by quoting that Good things come in small packages like this digital camera. Most of the good quality cameras are clear, high-quality prints so that one can capture the picture in a better way. Small cameras:The best part of a small digital camera is that this digital camera is smaller than a matchbox and stores a lot of pictures in its internal memory. Most of the manufacturers have a latest sensor, the all-new eight mega pixels four-color there was ignorance to all other changes that made a formidable combination with a high quality mechanically linked zoom lens. There are many spy cameras with functions that can be of a great use and chief among them it's super compact size and as it is of the size that is as small as a credit card that is beneficial for users to carry.

History Of The Computerflip-Flops - A Basic Counter

History Of The Computerflip-Flops - A Basic Counter

Flip-Flops - A basic counterWe looked at the Binary system, and basic computer logic elements, in previous articles, "It's a binary world - how computers count" and "How computers add - a logical approach".Now we can combine two parts of these articles to look at a counter. Another common logic element in a computer is a counter or timer. This can b to count items going past a sensor on an assembly line, or possibly a count-down timer. For example, if you have a late model washing machine it will have a simple computer using a count down timer to give 10 minute wash cycle, etc.There are several types of counter, nearly all of which use a basic element of electronics, the Flip-Flop. And you thought they were rubber shoes English people wear to the shower or the beach. (At this point Australians say "I thought they were called thongs").OK back on topic. The flip-flop is as old as electronics, and is a classic example of the binary system. It has two possible stable states, A or B, and can be 'toggled' from one state to the other, just like a 'push-on, push-off' switch. It was originally made with two vacuum tubes (or one, for example a double triode).It normally has two outputs, one being the complement of the other. That is,if one output(A) is a logic 0, the other(B) is a logic 1, and vice-versa. The input, or Toggle(T) is at logic 0 until a pulse from a sensor, for example, comes along. This pulse takes the logic state to 1, then back to 0. The toggle effect, causing the Flip-Flop to flip, is actually the CHANGE from 0 to 1. In logic terms the flip-flop is made up using AND and OR gates, in logic cicuitry it is just a 'black box' labelled FF. Several FFs may be grouped into yet another black box, a counter, timer, or multivibrator.We can make up a Truth Table, which we have used before. If you recall, a truth table tells you what the Output will be for all possible Inputs.TRUTH TABLE for Flip Flop - Toggle (C)hange,- Outputs A and B. INITIAL STATET B A0 1 0 'A' output is 0PULSE #1T B AC 0 1 'A' output is 1PULSE #2T B AC 1 0 'A' output is 0Now we string some flip-flops together to make a counter. Say we have a sensor on a beer bottling machine, which has to count 5 bottles before switching the feed, we need to count up to 5, or 101 in Binary. We will need 3 flip-flops, for binary bits 0,1 and 2, corresponding to decimal bit value of 1,2 and 4.We will take the A output of the 3 flip-flops to a decoder black box, which we can use to detect when we get to 5, then switch the feed. The B output of flip-flop 0 is passed to the toggle input of flip-flop 1 via an AND gate, so the next pulse from the sensor (which goes to all 3 flip-flops) at this AND gate will toggle the flip-flop, depending on the value of the B output, 0 or 1. Similarly the B output of flip-flop 1 goes to the toggle of flip-flop 3 via an AND gate.Our 3 Flip-Flops now come up with a truth table like this:-INITIAL STATEFF2 FF1 FF0TBA TBA TBA010 010 010 'A' outputs 000 - 0PULSE #1FF2 FF1 FF0TBA TBA TBAC10 C10 C01 'A' outputs 001 - 1[The (C)hange flips FF0 (always). FF1 & FF2 are blocked by the AND gate which needs a 0 input from the previous FF 'B' output AND the pulse change.]PULSE #2FF2 FF1 FF0TBA TBA TBAC10 C01 C10 'A' outputs 010 - 2[The (C)hange flips FF0 (always). FF1 flips beacause the 'B' output from FF0 is a 0 when the Pulse arrives. FF2 is blocked as before.]PULSE #3FF2 FF1 FF0TBA TBA TBAC10 C01 C01 'A' outputs 011 - 3[FF0 flips, FF1 is blocked again,as is FF2.]PULSE #4FF2 FF1 FF0TBA TBA TBAC01 C10 C10 'A' outputs 100 - 4(FF0 flips, FF1 flips, FF2 flips.)PULSE #5FF2 FF1 FF0TBA TBA TBAC01 C10 C01 'A' outputs 101 - 5 count complete![FF0 flips, FF1 and FF2 are blocked.]This counter can count up to 111, 7 decimal, it then resets to 0. A couple of interesting points to note are:-1. FF0 flips every pulse. FF1 flips every 2 pulses. FF2 flips every 4 pulses etc. These facts can be used to make up a divider, which can be cascaded. For example the 4 pulse output can go to a second counter which also gives a 4 pulse output, totalling 16. This can be expanded to make up a decadic counter by decoding a count of 1010 (10 decimal) and using this to toggle the next counter, etc. What about 60 and 12 for your digital watch?2. Look at the 'B' outputs from the counter. In sequence the values are:- 111, 110, 101, 100, 011, 010 (7,6,5,4,3,2 decimal). See the pattern? That's right - a countdown timer! We'll be using this in a later article.

How to Meet that Special Someone

How to Meet that Special Someone

Chances are unless you are very lucky you will go thru many different relationships before you find your special someone. Finding your sole mate is like gambling. In poker and blackjack you may have to play dozens of hands until you get a winning hand, and it is the same with relationships.During your life you will probably meet some people who seem like they may be the one, or that they are close, but still have the feeling that something else is missing. My advice is that if you are not happy, because something seems like it is missing, then it usually is not right.Before I found my special someone, I was in a relationship for over 10 years, and I thought everything was great, until I started to seriously consider getting married. Then I noticed that we had so little in common and in reality wanted so many different things out of life and one day we both realized there was much about each of us that we both wanted from someone, but it was not us that we wanted.Then one day I decided I had enough of trying to go to clubs and bars to meet people. I was sick and tired of trying to find someone in the time it takes to finish a drink. It always seemed the ladies I would meet were all wrong for me, or they seemed great after talking to them for 5 minutes but they seemed to have no interest in me.Then one day I had an idea, it was not an original idea but I decided to use the internet to try to find the right person for me. So I proceeded to make a myspace profile. On this page I tried to put the real me and not the funny guy trying to be charming that was looking for love at the bar.And as I would at the poker rooms I went all in, I poured my heart and sole into this. I wrote what I wanted and wrote down who I truly think I am and not who I want to be, and I was rewarded by 1 email responding to my site.It was amazing; the response I got was like a dream. Imagine you are sitting in a Las Vegas casino playing poker. You are down to your last few dollars, you go all in and you wind up being dealt a Royal Flush, and suddenly the sky is bluer, the grass is greener, and all your worries seem to just fade away.At first things were a little awkward for the both of us. We decided to hold of on actually meeting until we got to know each other first. We spent a month just talking everyday on the internet. You can really open up to someone and show them the real you and not have to worry about rejection on the internet, after all you are just a faceless ghost, and if things dont work out you could be sitting next to her on the bus one day without ever knowing it.The key to finding happiness is realizing you are going to bust more then you are going to get blackjack, but you must keep trying, trying to remember you only need to find the real thing once.

How does proactive spyware research work

How does proactive spyware research work

Phileas' purpose is to detect spyware programs before they reach unaware PC users that surf the Internet. This proactive spyware research approach is to revolutionise the way how internet security companies do their research on newly identified threats, malware and spyware available on the Web.Phileas doesn't follow the standard report-research pattern when it comes to finding new ways to tackle malicious software. To the contrary, it crawls the Web and updates the threat database automatically by transferring information about its findings to Webroot's central unit. The information is being gathered via sophisticated Phileas bot network that crawls the Internet 24/7 sends results to Webroot for processing. Phileas can detect malicious code, exploits and suspicious applications using its detection algorithms Phileas bots scan Web sites for forged URLs, manipulated scripts and for susItpicious applications. If they come across a potentially dangerous site, the security researchers target the website or application scrutinizing the information.The bot network identifies known threats and forwards information about unknown suspicious programs for processing to Webroot. This data is being used to create spyware definitions.Webroot's application is collecting gathering data related to exploits and malicious code that are being used to transport spyware on the Internet and about the spyware's originator.Historically, anti-spyware vendors had relied on the Internet user community's reports about new spyware. Phileas relies on a proactive approach that aims at collecting research data and information about new flaws and exploits by actively scanning the Web for potentially malicious code.

Backgammon Rules: Learn How to Play Backgammon

The board game backgammon is one of the most ancient games known to man. It is believed that early variations of the game were played in Ancient Egypt, Mesopotamia and Ancient Rome. Since then, the game has evolved, changed several names and spread to different parts of the world. It is currently a popular pastime all over the US, East Asia, Europe, and the Middle East. In order to play backgammon all you need is a partner, two dice and a special backgammon board with checkers. The "backgammon board" is divided into two sides with each one is the mirror reflection of the other. Each side contains 12 triangles called points numbered from 1 to 24. Points 1 to 6: Home Board or Inner BoardPoints 7 to 12: Outer Board7 point: Bar Point13 point: Mid PointAt the starting position of the game, each player has 2 checkers on the 24 point, 3 checkers on the 8 point and 5 on the 13 and 6 point. Each player moves from his home board through the outer board towards the opponent home board. The object of backgammon, then, is to move your checkers towards your opponent home board and remove them off the board before your opponent moves his checkers towards your home board. The speed of the progress of each move is determined by the outcome of the dice roll. The backgammon play begins with both players tossing one die. The player whose outcome is the highest, makes the first move using both his and his opponents number. If the outcome of the dice toss is even, the players toss the dice again until an uneven outcome appears. From now on, each player tosses both dice on his turn. After each toss of dice, you should move your checkers forward the number of steps appears on both dice. You can move either one checker the number of steps summed up by both die or move two checkers. To make it clearer: if the outcome of the dice roll is 5 and 4, you can either move one checker 9 steps forward or move one checker 5 steps forward and then move the other piece 4 steps forwardIf the dice rolls a double, which means an even number on both dice, you can move double the number appears on the dice. For example, if you roll double 2, you can move 2 points four times. In that case, you can either move one checker 8 steps forward; move two checkers a total of 4 steps; move two checkers a total of 2 steps each plus a total of 4 steps; move one checker a total of 6 steps plus 2 steps; or move four checkers 2 steps.You can move a checker to a point where there is another one of your checkers or no more than one checker of your opponent, called blot. When you hit a blot, it is moved to the middle of the board to the part divided between the home board and the outer boards, called the bar. The checkers placed on the bar are kept out of play until the bar can be entered by a dice roll in the opponents home boards. For example, if you roll 2, you can enter a checker to the 23 point and enter the opponents home board and re enter the bar checkers into the game. You cannot move the other checkers unless your entire bar checkers are at your opponents home board. By the time your checkers are in your home board, you must remove the checkers from the board, to bear off, using a roll of dice. For example, if you roll 1, you can bear off one checker from the 1 point; if you roll 2, you can move a checker form the 2 point, and so on. If your opponent has not borne off any checkers while you have borne off 15 checkers, you win the gammon. If your opponent has not borne off any checkers and still some of his checkers are placed on the bar, while you have borne off 15 checkers, then you win the backgammon.

Implementing Service Management: Part 1 - Service Level Management

What is Service Level Management?Service "Level Management" is one element of the 11 ITIL disciplines, and details the need to plan, draft, agree, monitor and report on service achievement within the business. It also incorporates the requirement for an organisation to implement actions to eradicate potential unsatisfactory service.Service Level Agreements are one component of Service Level Management; these are documented agreements and are written from the perspective of both the supplier and recipient or end user. These agreements dictate the Service Levels and include services provided, metrics, responsibilities and help to ensure that all support requests are responded to and fixed within the agreed timeframes.Implementing effective Service Level Management can dramatically increase an organisations ability to respond to and fix users requests. Emma Anderson, Service Manager (SSI Computer Services)Why introduce Service Level Management?Service Level Management is fundamental to an effective service provision, however its a topic not widely discussed among organisations looking to improve their Service Delivery. Most organisations have the impression that new tools alone will increase their organisations ability to respond to a growing number of requests. In fact, a major factor in Service improvement is in the ability of the IT resource to understand its own limits and set realistic Service Level Agreements (SLAs) with its own end users. This enables the service department to provide a reliable, and more importantly, repeatable service to its users, which in turn raises the IT Service perception in addition to service delivery itself.How best to introduce Service Level Management into the Business?When implemented successfully Service Level Management benefits can be achieved by organisations who embrace the methodologies, however, careful planning must be taken into consideration before undertaking this sort of service improvement process. As mentioned previously an assessment must be made of the service provision before any SLAs can be agreed with end users. If the Service provision itself is unable to provide the service requested by the end user community a decision must be made as to whether the service department gear-up or make alternative arrangements to meet the users expectations for example outsourcing or 3rd party assistance.Educating the end user community is a key factor in implementing Service Level Agreements and ensures that the users are aware of the service they should expect to receive. This process should be in partnership with the end users as buy-in at this stage ensures a smooth transition.
