“Our deeds, our feelings, our thoughts, and our sensations just happen of themselves, as the rain falls and the water flows along the valley. I am neither a passive and helpless witness to whom they happen, nor an active doer and thinker who causes and controls them. “I” is simply the idea of myself, a thought among thoughts. Taken seriously it gives the illusion of being something apart form nature, a subject reviewing objects. But if the subject is an illusion, the objects are no longer mere objects. Inside the skull and the skin as well as outside, there is simply the stream flowing along of itself.”

— Alan Watts

How to fake a credit card number ? - 101

If you are thinking - ‘Dude, its a bunch of numbers, can’t i just make my own credit card number?’. Well, then this post is for you.

You see in order to ensure that people don’t game the system, credit card companies have a simple set of rules. ( a checksum )

“Mod-10″ Algorithm

The Luhn algorithm or the mod-10 algorithm is what you need to beat. Its used to validate a lot of things from credit cards to social security numbers.

Say you have a credit card whose number is 4012-8888-8888-1881. In order to check whether the credit card is a valid one, then we have to do a really simple mathematical operation.

                        Double every other number and add them. Call this sum - x

Add the rest of the numbers. Call this sum -y

If (x+y) is a multiple of 10, then its a valid card, otherwise its not.

Valid credit card numbers

The last number in a credit card is known as a ‘checksum’ and it plays a vital role.

According to this, only 4012-8888-8888-1881 is a valid card number. not 4012-8888-8888-1882, 4012-8888-8888-1883,4012-8888-8888-1884, 4012-8888-8888-1885 …… 4012-8888-8888-1889.

( because they their sum is not a multiple of 10 )

Of course, although this was good enough algorithm in the 20th century, with high processing power you can do much more than a simple mod 10 test.

Therefore, the present day check sum although is based on this, is packed with much more fascinating mathematics.

( Verhoeff algorithm, Damm algorithm, Luhn mod N algorithm are some good places to start on your quest )

Have a great day!

ISBN Number

The same mod sum is used to validate books as well. But instead of simply adding them up, you multiply each number by a weight and then add them.

If the resulting sum is a multiple of 11, then its a valid ISBN number

“What I didn’t realise was that important philosophical differences divided the work of [Albert] Camus and [Jean-Paul] Sartre. Much as they liked Camus personally, neither Sartre nor [Simone de] Beauvoir accepted his vision of absurdity. For them, life is not absurd, even when viewed on a cosmic scale, and nothing can be gained by saying it is. Life for them is full of real meaning, although that meaning emerges differently for each of us. As Sartre argued in his 1943 review of ‘The Outsider’, basic phenomenological principles show that experience comes to us already charged with significance. A piano sonata is a melancholy evocation of longing. If I watch a football match, I see it as a football match, not as a meaningless scene in which a number of people run around taking turns to apply their lower limbs to a spherical object. If the latter is what I’m seeing, then I am not watching some more essential, truer version of football; I am failing to watch it properly as football at all. Sartre knew very well that we can lose sight of the sense of things. lf I am sufficiently upset at how my team is doing, or undergoing a crisis in my grasp of the world in general, I might stare hopelessly at the players as though they were indeed a group of random people running around. Many such moments occur in 'Nausea’, when Roquentin himself flummoxed by a doorknob or a beer glass. But for Sartre, unlike for Camus, such collapses reveal a pathological state: they are failures of intentionality, not glimpses into a greater truth. Sartre therefore wrote in his review of 'The Outsider’; that Camus 'is claiming to render raw experience and yet he is slyly filtering out all the meaningful connections which are also part of the experience’. Camus, he said, was too influenced by David Hume, who 'announced that all he could find in experience was isolated impressions’;. Sartre thinks life only looks pointillist like that when something has gone awry. For Sartre, the awakened individual is neither Roquentin, fixating on objects in cafés and parks, nor Sisyphus, rolling a stone up the mountainside with the bogus cheerfulness of Tom Sawyer white-washing a fence. It is a person who is engaged in doing something purposeful, in the full confidence that it means something. It is person who is truly free.”

— Sarah Bakewell, ‘At the Existentialist Café’
