Python palindromic quine

Posted January 28th, 2011 by ch3ka

A palindromic quine is a program which prints itself, and reads from right to left the same as from left to right.

Python is my favourite programming language, but since it is designed to be readable, it is very hard to "codegolf" - where you want to express your program in the shortest possible way.

Last month, I hacked this in a codegolf session:
_='#)]1-::2-[l+l(tupni;`_`+"=_"=l;';l="_="+`_`;input(l+l[-2::-1])#'=_

Yes, this

  • is a valid python program
  • is a python quine
  • is palindromic

    • and it's only 69 chars long!

Hacking Single Lens Reflex Cameras with Barcodes

Posted March 24th, 2010 by ch3ka

Cool Stuff :D

The Elan/100, like its predecessor the 10/10s, works with an optional Barcode Reader E accessory. This was an experiment in simplifying the camera’s user interface for novices. Or, to be less charitable, an expensive gadget-driven idiot mode.

How to golf in python

Posted March 14th, 2010 by ch3ka

Had some fun in c.l.py.
Given was:

def fizzbuzz(num):
> if num:
> if num % 15 is 0: return fizzbuzz(num-1) + 'fizzbuzz \n'
> elif num % 5 is 0: return fizzbuzz(num-1) + 'buzz \n'
> elif num % 3 is 0: return fizzbuzz(num-1) + 'fizz \n'
> else : return fizzbuzz(num-1) + ('%d \n' % num)
> return ''
> print fizzbuzz(100)

Since this was not funny enough, I wrote:
for i in range(1,101):print('','fizz')[not i%3]+('','buzz')[not i%5]or i

This works because not casts to bool and (True, False) == (1, 0).

Filmtipp

Posted March 12th, 2010 by ch3ka

Weil wirs heute erst von Filmen hatten:

Wer "Postal" mochte, wird "War Inc" lieben.

Total bescheuerter Film. Also wirklich.
Minus 5 Sterne.

Aber so bescheuert er auch ist, er ist herrlich sarkastisch was die globale Situation angeht. Und dabei nur ein ganz klein bisschen überspitzt.

Im Gegensatz zu Postal hat die weibliche Begleitung auch keine Anzeichen starker Angewiedertheit gezeigt, aber das kann daran liegen dass es eine andere ist ;)

Radio Station called

Posted March 12th, 2010 by ch3ka

I just got interrupted in my work by a call from a radio station.
It was a radio quiz and I was live on air - funny feeling.

They played a short audio sample of a movie and I had to guess the title of the movie.

Well, what should I say... I knew the title in the first two seconds because I heard "Verpasst du auch nem Mann ne Fussmassage?" - And that's of course the german wording in one of the best scenes in one of the best movies ever made - Pulp Fiction

Lucky me they picked this one ;) I won a CD and now... back to work :)
