Hey Fediverse! I would like to create a little game with some mini-puzzles coming from the world of "hacking"/crypto. I would like it to be very simple so I thought of asking to decode a Morse code sentence, or decipher something encrypted with Cesar cipher (or even a simpler one).
Hey vous savez, le filtre “vieux” sur #faceapp ?
En fait on peut l’appliquer, puis l’appliquer à nouveau, puis encore une fois, et à la fin on ne dort plus jamais de sa vie quand on voit les résultats.
Here are #animated #gifs of the representation of #NumericalIntergration #approximations with increasing numbers of strips. Represented are the Rectangle Method, Trapezium Rule and Simpson’s Rule. Note how much faster the second and third methods improve the approximation the exact blue curve in each case as the number of strips increases. Produced using #wxmaxima. They are all available on #Wikipedia.
Il y a trente ans, les dividendes représentaient moins de 5% de la richesse créée dans l’industrie ; aujourd’hui, cette part s’élève à 25%. Pour tout euro d’investissement net, les entreprises distribuaient 0,50€ de dividendes en 1978, contre 2€ en 2011. https://www.monde-diplomatique.fr/2019/07/RAIM/60025
There exists infinitely many prime numbers p such that p-2 is also prime.
There exists a unique prime number p such that p-1 is also prime.

Un petit coup de pouce ?
Yesterday I discovered that in Python the lists `[]+[]` and `2*[]` look the same but are not the same...
I had a hard time debugging a program because of that 🙃...
>>> L = [] + []
>>> L = 2*[]

We are one step closer to finding the discrete logarithm easy! 
Given g, y ∈ Fₚ, when you have
gᵈ = y
the discrete log problem is to find d.
It is a hard problem in general, and it was at the root of lots of cryptographic applications. It's not so trendy today because quantum computers break it. The result in  is valid with classic computers though!
