  • metamero: this enormous evolving minefield certainly deserves your fullscreen #gameoflife behind the scenes
  • metamero: c.width|=n=128;M=(t?M:[...Array(y=72*n)]).map((v,k)=>t?([n,1,n-1,n+1].map(d=>v+=M[(k+d+y)%y]+M[(k-d+y)%y]),v&&x.fillText(v,2+15*(k%n),9+15*(k/n|0)),v^4?v==3:M[k]):Math.random()>.5)

  • metamero: #Unicode code point ⇄ char converter : left is code point in decimal 🔃 right is character : useful for copying individual combining marks #tool
  • metamero: use ctrl-a then ctrl-c to copy the combining mark on its textarea. then you can it use by pasting after the character you want to modify. once a character is modified, often you can't select just the combining mark anymore, so this little dweet can help to choose and select diacritical and other combining marks. you can try all unicode range e.g. 휂 55042 U+D702. zoom in ;)
  • metamero: focus and edit any field then click out of it

  • metamero: this graph shows the fast convergence of u/Xen 's algorithm for golden ratio
  • katkip: I don't understand anything
  • pavel: A and B are sequential Fibonacci numbers, their ratio tends to the golden ratio.
