In Python we can emulate multiline comments using triple-quoted
strings, but conceptually strings and comments are very different.
I.e. strings are objects, comments are auxillary text discarded at
compile time. Strings are objects created at runtime, comments are
not.
The answer from Steven D'Aprano:
Guido's time-machine strikes again.
>>> import dis
>>> def test():
... x = 1
... """
... This is a triple-quote comment.
... """
... return x
...
>>> dis.dis(test)
2 0 LOAD_CONST 1 (1)
3 STORE_FAST 0 (x)
6 6 LOAD_FAST 0 (x)
9 RETURN_VALUE
String literals -- not just triple-quoted strings, but any string
literal -- that don't go anywhere are discarded by the Python compiler,
precisely so they can be used as comments.
He expressed anguish over “all sorts of lies” published about him in a section of the media that he went to school and pre-Science in Chidambaram, the Tamil Nadu temple town where he was born in 1952.
“People I don’t know, for example a Mr. Govindrajan, claim that they were my teachers at Annamalai University which I never attended, since I left Chidambaram at the age of three,” Dr. Ramakrishnan clarified.
Dr. Ramakrishnan said that it was a good thing if his winning the Nobel Prize encouraged people to read about the work, read books and take interest in science.
“But I, personally, am not important. The fact that I am of Indian origin is even less important. We are all human beings, and our nationality is simply an accident of birth,” he said.

Brainfuck is easy and interesting.
We work on cells, like if you know c, cell is like ptr = unsigned char *
+ stands for increment like ++*ptr
- stands for decrement like --*ptr
> goes one cell right like ++ptr
< goes one cell left like --ptr
. spits out output like putchar(*ptr)
, expects input. like *ptr = getchar(stdin)
[ is the start of while block test condition (for non-zero) which is like while(*ptr) {
] is the end of the block }
And everything else is comment, like the these sentences.
The above program is designed to output "Hi" and if you include these
sentenses too, it will print "Hii" and wait for some input and enter
presses till the cell becomes zero.
Isn't it cool? :)
BTW, you can run this program using an interpretor called (bf) just an apt-get away.

In order to say exactly what recursion is, we first have to answer "What is recursion?"

Lake Wobegon Effect
An eccentric billionaire places before you a vial of toxin that, if you drink it, will make you painfully ill for a day, but will not threaten your life or have any lasting effects. The billionaire will pay you one million dollars tomorrow morning if, at midnight tonight, you intend to drink the toxin tomorrow afternoon. He emphasizes that you need not drink the toxin to receive the money; in fact, the money will already be in your bank account hours before the time for drinking it arrives, if you succeed. All you have to do is. . . intend at midnight tonight to drink the stuff tomorrow afternoon. You are perfectly free to change your mind after receiving the money and not drink the toxin.
Kavka's theory is that, one cannot intend to do something which one won't do.
There is an analysis of payoffs from different scenarios and the real-world example of this puzzle is:
...the Political Manifesto. Before an election, a political party will release a written document outlining their policies and plans should they win office. Many of these promises may be difficult or impossible to implement in practice. Having won, the party is not obligated to follow the manifesto even if they would have lost without it.
I stumbled on this word while reading this one:
Still a joke that "TAOCP is a book that is almost exclusively loved by those who haven't read it" makes some sense as snobbism in programming is not that different from snobbism in other areas.

- Espress
- This is the base flavor, brewed by passing hot water under high pressure through finely ground coffee beans.
- caffè latte
- This is Coffee and Milk
- Cappuchino
- This is Espreso and Milk foam. This contains less milk than latte.
