Visually delight stuff & some research in between |
I was reading an article today in one of my favorite publications about how to get free trials without actually using your credit card by generating valid credit card numbers using a simple algorithm called the Luhn check. So I wrote a little script that generates credit card numbers that will be deemed valid by most software checks. This will work because the service won’t know that the credit card is invalid until they actually try to charge it. Well, the card may be valid since my script uses random numbers. Obviously this if for informational purposes only and should never actually be used.
Most credit card numbers are validated using an algorithm called the “Luhn check”. This is a very simple algorithm that doubles the odd digits and does a sum to see if the number is divisible by 10. The credit card companies use a slightly different version that involves a check digit as the last digit. To generate a credit card number that will pass most validation software (as long as they don’t actually try to process the credit card) one only needs to follow these steps to make sure that the generated credit card is valid
In the wake of these studies, I think there are three easy techniques that can help to maximise good fortune:
- Unlucky people often fail to follow their intuition when making a choice, whereas lucky people tend to respect hunches. Lucky people are interested in how they both think and feel about the various options, rather than simply looking at the rational side of the situation. I think this helps them because gut feelings act as an alarm bell - a reason to consider a decision carefully.
- Unlucky people tend to be creatures of routine. They tend to take the same route to and from work and talk to the same types of people at parties. In contrast, many lucky people try to introduce variety into their lives. For example, one person described how he thought of a colour before arriving at a party and then introduced himself to people wearing that colour. This kind of behaviour boosts the likelihood of chance opportunities by introducing variety.
- Lucky people tend to see the positive side of their ill fortune. They imagine how things could have been worse. In one interview, a lucky volunteer arrived with his leg in a plaster cast and described how he had fallen down a flight of stairs. I asked him whether he still felt lucky and he cheerfully explained that he felt luckier than before. As he pointed out, he could have broken his neck.
