Cricket Startegy (Match IndiaVs New Zealand As Example)

Cricket fans reading this, please correct me if I'm wrong, and forgive my use of the wrong terminology. (For instance, when a cricketer bats, can you also say he "hits"? I hope so.)

The idea, I think, is this:

In cricket, a batter will hit until he makes an out, and which point he is replaced and will not bat for the remaining of the innings. Batsman’s hit in pairs. Once ten of the eleven men are out, that leaves only one, who can't bat alone, and the innings ends.

Outs can be infrequent; typically, a batsman can hit for 25 runs or more before making out, and good batters occasionally hit for 100 runs or more. Therefore, an innings (or one part of the game) can go on for several days.

The best batsman’s normally come to bat first. Sometimes, one of the better batsman’s will go out late in the day. When that happens, the team will sometimes send up a worse batsman to end the day. That batsman is called the "nightwatchman."

Why would they do this? According to Cricket Board or Council, the idea is that the end of the day is a bad period in which to hit – the next batsman may be tired, or the light may not be good. Also, if they do send up the good batsman, and he is quickly put out, the psychological effect might hurt the team.

And so, they sometimes put in an inferior batsman, who can waste some time between now and dusk, so the better batsman can be saved until Next Day Play.

Now, if all this is correct, what would be the strategic advantage? Every batsman has to hit eventually, and there is no inherent benefit of putting good batsman’s together as in baseball, because every batter comes up in the same situation (the equivalent of "bases empty"). And the psychological rationale seems weak to me.

That leaves the "hard to hit in the dark" hypothesis. If the dim light causes all players drop by the same percentage, then it makes sense to put in the batter who normally bats for 10 runs than the one who normally bats for 35 runs. Better to lose X percent of 10 then X percent of 35. But isn't it also possible that it's the other way around? Maybe the better the batter, the more able he is to handle the adverse conditions.

Also, you have to keep in mind that every batsman gets the same chance to bat, except the one who's left after ten men have gone out. The longer you wait before putting in your best batsman’s, the greater the chance it will be one of those good ones who doesn't get to finish. So, generally, you'd want your better batsman’s first.

So which is the better strategy? This seems like a good problem for cricket sabmetrics. The original article points to a study by Charles Davis, who (I get the impression) is cricket's foremost sabmetrician.

In that study, Davis finds that teams who used the night watch man strategy (late in the day after two men had gone out) undershot expectations by 25 runs over teams who didn't. It wasn't because the night watch men didn't do well – they did about the same as their career average lower in the "batting order." So it must have been ... what? May be stranding a better batsman after the last out? That still seems like a lot; the difference between a good batter and a bad batter might be ... what, 50 runs? And there are still 8 outs (wickets) left in the match. So the fraction 25/50 seems too large under the circumstances.

But look at Davis's graph: an increase of 100 runs scored in the first two wickets leads to a final score only about 35 runs higher. That shouldn't be the case, should it? Wickets are independent except for the identities of the players involved. Consider a baseball analogy: if the Houston Astros score three runs in the first two innings, wouldn't you expect their final score to be three runs higher than if they scored zero runs in the first two innings? Why isn't that happening in Davis's study? The only thing I can think of is that if you score more runs in the first two wickets, it's because you've used up your very best batsman’s, and all that's left is your weaker ones. In that case, it means that team strategy is a huge factor in the distribution of scoring. And so, when you divide innings into "nightwatchman" and "non-nightwatchman," you can't assume the two groups are identical, as Davis did.
Again, please correct me if I've assumed something incorrectly, and I'll update this post.

Manage Your Budget With Easy To Use Personal Finance Ideas

December 14th, 2011

Dealing with your personal finances can be stressful and difficult. When you gain knowledge about the subject though, it’s easier to deal with money. In this article, you will be provided with some information on how to best deal with your personal financial matters.
Practicing patience can prevent you from overpaying for the things you desire. People clamor to buy the newest electronics without even thinking about the cost. For instance, you can save a lot of electronics by waiting for the price to drop. This will give you much more money to use for other things.
No person desires eviction or foreclosure. Consider getting a cheaper house with cheaper rent or payments if you’re in a bad place financially. You don’t want to be kicked out of your own home once your efforts to repay fail. It is far better to sell or move out of your home of your own accord.
Never believe that a credit repair organization can guarantee success in improving your history. A lot of companies out there make vague statements about how they will repair your credit history. But what worked for someone else may have no bearing on your credit issues. It’s simply not a case of ‘one size fits all’ when it comes to credit repairs, so there can be no guarantee of success.
You can’t successfully manage personal finance without saving money. Saving money should be a top priority , not one that you keep putting off. You can tell yourself that having to save is part of your bill paying process. By doing this, you will start to build up an emergency fund.
Check your credit report regularly. Many resources allow you to view your credit score free of charge. Request a free credit report two or three times per year and look for charges you didn’t make, accounts you didn’t open, or other suspicious activity that suggests someone has stolen your identity.
You can improve your finances dramatically by taking advantage of available discounts. Lose your affiliation to certain brands and only buy when you have coupons. For instance, if you regularly purchase a specific brand of detergent, you should start prioritizing other brands if there are coupons available.
Create a budget and follow it until you are able to dig yourself out of debt. Whether you prefer a pen-and-paper approach or software that you can use on your personal computer and smartphone, a budget helps you to pinpoint spending habits that you can change. It can also help curb unnecessary spending.
Try seeking out non-essential areas on your expenditures and cut back on them if you notice you have no money left after paying your expenditures. For instance, you may not be able to handle not going out to eat dinner at all for long. Though, if you decrease eating out each month by half, you can conserve funds and still appreciate dining out.
Loan
Making sound, responsible financial decisions begins by avoiding debt whenever possible. Taking a guaranteed payday loan for a car or a house is acceptable, as long as you can afford it. When it comes to the smaller, everyday expenses, though, credit is a bad way to meet your needs.

To ensure financial stability, you should open an account that you can put some savings in and deposit to it on a regular basis. You will be able to face unforeseen events and will not have to get a loan when you’re strapped for cash. You may not be able to put much in each month, but it is still important to save regularly.
Like the introduction of this article said, dealing with your personal finances can stress you out. Knowing ways to deal with your finances can aid you in lowering your stress. The purpose of this article has been to help relieve some of your financial stresses and offer you some guidance on how best to move ahead.

Captcha Work

2011-12-26T06:03:00.003-08:00

similarly, it's unwise to build a CAPTCHA that doesn't distort letters and numbers in some way. An undistorted series of characters isn't very secure. Many computer programs can scan an image and recognize simple shapes like letters and numbers.

One way to create a CAPTCHA is to pre-determine the images and solutions it will use. This approach requires a database that includes all the CAPTCHA solutions, which can compromise the reliability of the test. According to Microsoft Research experts Kumar Chellapilla and Patrice Simard, humans should have an 80 percent success rate at solving any particular CAPTCHA, but machines should only have a 0.01 success rate [source: Chellapilla and Simard]. If a spammer managed to find a list of all CAPTCHA solutions, he or she could create an application that bombards the CAPTCHA with every possible answer in a brute force attack. The database would need more than 10,000 possible CAPTCHAs to meet the qualifications of a good CAPTCHA.

Other CAPTCHA applications create random strings of letters and numbers. You aren't likely to ever get the same series twice. Using randomization eliminates the possibility of a brute force attack -- the odds of a bot entering the correct series of random letters are very low. The longer the string of characters, the less likely a bot will get lucky.

CAPTCHAs take different approaches to distorting words. Some stretch and bend letters in weird ways, as if you're looking at the word through melted glass. Others put the word behind a crosshatched pattern of bars to break up the shape of the letters. A few use different colors or a field of dots to achieve the same effect. In the end, the goal is the same: to make it really hard for a computer to figure out what's in the CAPTCHA.

Designers can also create puzzles or problems that are easy for humans to solve. Some CAPTCHAs rely on pattern recognition and extrapolation. For example, a CAPTCHA might include a series of shapes and ask the user which shape among several choices would logically come next. The problem with this approach is that not all humans are good with these kinds of problems and the success rate for a human user can drop below 80 percent.

Medical transcription

2011-12-26T06:00:00.000-08:00

What Really IS Medical Transcription?

Very simply, medical transcription is the transcribing (typing) of doctor's reports from dictated audio files. Each time a physician or other medical provider sees a patient, a record is kept -- the medical record.

Insurance companies have now made typed notes mandatory, which means the need for medical transcription has nearly tripled in the last decade. Add to that the baby boomers who are reaching their senior years, and you have a wonderful career opportunity and a bigger demand than there is supply for the correctly trained personnel to transcribe these records.

What is even better is that with the invention of the Internet and encrypted e-mail, local transcription services can help doctors' offices and hospitals all around the country, and even around the world. The best news is that they hire qualified individuals who work from their home to do this work for them.

What does this mean for the work at home transcriptionist? Quite a lot. First, the work at home transcriptionist can forget about early morning traffic, or rush hour traffic on the way home. They no longer have to put up with corporate America and can usually set their own hours for working. Babysitters are a thing of the past when mothers are home to greet their children after school. And tensions are eased when the paychecks are equal to (and many times more than!) the income she used to bring home.

But it's not all peaches and cream! There are a number of factors that go into making this dream a reality. Most importantly is the training you receive. Do you go with the quick course that will have you working in only three months? Or do you choose the longer course that takes a year to finish?

From experience we've learned what works and what doesn't. And what doesn't work is a cheap course such as those found in ads in the back of magazines. The programs may look glamorous, but essentials are lacking -- essentials that may mean the difference between your success and your failure.

What makes a medical transcriptionist qualified?

What most people don't realize is that the qualified medical transcriptionist is worth every dime she makes (and more!) However it's not just the typing speed that decides your success -- it's far more. Things like working SMARTER instead of HARDER. Things like being trained in ALL aspects of the transcription business instead of just a few medical specialties. Things like knowing your computer inside and out and knowing little tips and shortcuts that take the job from an average one to an extremely profitable one.

Don't get us wrong -- we're not saying you are going to make big money your first year. Maybe not even your second year. But if you were to learn transcription and work at home, wouldn't you want to learn it from the very best? Wouldn't you want your training to come from people who have successfully already DONE what you want to do? What if those experienced individuals got together and created a program so thorough and so intense that you could cut months off your learning curve? Wouldn't that be worth looking into?

Well that's exactly what has happened here. In our FREE e-book (see link above) you'll get in-depth reports and stories from a number of successful transcriptionists around the country -- each one telling you what worked for them and the mistakes they made first starting out.

What better way to make your decisions than by getting advice from the people who have been there before you? People who have learned the ropes the hard way. Now you can benefit from this knowledge!

For a good example, if you wanted to learn oil painting, would you rather learn from your next door neighbor who dabbles in weekend art, or from a renowned artist who has many years of experience in both painting and the business of selling their painting? This is how an investment in yourself at the beginning of your career can make the difference between you earning an average or below-average income and one that is well above-average. The payoff over even just a few years (many times only a few months!) is well worth the difference in cost!
