Chapter 2 Extra exercises
|
I (and perhaps others) will be posting some exercises here. These are not really bound to chapter 2, people can make them whenever they want, but the exercises in this thread assume you've read Chapters 1 & 2.
Let's see if this'll revitalize this... |

Aronofsky's Fountain
|
A trailer is finally out for The Fountain (by the same director who did Pi and Requiem for a Dream). It certainly is beautiful, kind of reminds me of The Cell (visually).
I've read the graphic novel, it's quite... special, and I can't but have tha... |

Reachability of temporaries

For an assignment I have to write a few audio filters using the javax.sound.sampled package. You are given bytes, which you have to combine into samples, then separate the channels, apply the filters, interleave the channels and finally convert it ba... |

(C#) Issues with explicit casts and generic functions
|
Quote:Original post by macnihilist
I'm no C# expert, but isn't this simply a boxing issue?
object x = 5.0;
int y = (int) x;
raises an exception. I guess that makes you right. |

(C#) Issues with explicit casts and generic functions
|
I have no answer for you, and it puzzles me too. I reproduced the abnormality in a shorter, clearer piece of code:
public static void Main( string[] args )
{
var dic = new Dictionary<string, object>();
dic["five"] = 5.0;

Daan's Icon. I guess I like simplicity. And cowboys dancing with vacuum cleaners. |

Best Languages to start with?
|
I would suggest Python for the language, or C# for the tools.
Python is a simpler language than C#, which is important when evaluating languages in the context of learning to program. It's useless to start with a complicated language like C++ whic... |

We don't give a crap. If only there was a language called Excuse. Very loose syntax, and you aren't responsible for the outcome of the program.

I'm not even sure we ever even hear her on the phone.
We do, but only a few words. She has some kind of accent, probably French so that it fits with Mal's.

Wow, you're right. I had completely glossed over Mal (BTW, latin for "bad", or "evil"). Ariadne (BTW, in Greek mythology, Ariadne helps Theseus navigate the Labyrinth and defeat the Minotaur) tells Dom Cobb (shor... |

Then how do you explain Cobb's kids being dressed and looking exactly the same way he remembered seeing them the last time, when it must've been quite some time passed since then.
They just happen to wear the same... |

(spoilers)
I don't see how the ending would open up a path towards a sequel, it was fairly predictable that such an ambiguity would be inserted at the end. I have to admit I was a bit disappointed by it, it seems too much like "the typical thing t... |
