Alexis King

@JonasCz If you're really interested, the runtime is here and the "compiler" (which is really just a parser) is here.

bjb568

@hichris123 I don't have 5 cores.

@JanDvorak Well, that's what you have to do to run a flash game 600x400 at 30fps.

Alexis King

There's also a "standard library", but it's tiny. I wrote some other libs, like a regex library, but I never put them on github.

hichris123

Er?

Tim Post

@AlexisKing It took me nearly a year of fumbling around with lemon to come up with a config 'language' that evaluated stuff independently of the shell. The parser was the easiest part to learn.

hichris123

6:01 PM

My laptop charger is rated for 4.8A output.

Alexis King

@TimPost I just wrote a recursive-descent parser myself, mostly because my syntax was Lisp-y enough to be really easy to parse.

So I got to focus on semantics rather than syntax for the most part. :)

AstroCB

@ShadowWizard Yes; we'll see how it goes.

bjb568

@bjb568 45W, not A obviously

about 15V @3A

Tim Post

@AlexisKing I said "I'm a horrible programmer" and table-flipped probably 20 times before I started learning how not to syntax myself into a very dark corner.

hichris123

@bjb568 Then why's that say 37A?

hichris123

Alexis King

@TimPost I spent most of my head-desking in GDB trying to figure out why everything was segfaulting with no support for debugging information. :P

Jan Dvorak

what voltage??? 0.1 volts?

hichris123

I = V / R

bjb568

1.8V on the CPU

hichris123

6:04 PM

Or V = I * R

Jan Dvorak

37A / 1.8V will kill your CPU

bjb568

Come on give me some slack, I don't have any idea what I'm doing. I was 5 when I last played with those equations.

I can only guess that your professor feels it is an overpowered tool. For example, the classic limit $$\lim_{x\to 0} \frac{\sin(x)}{x}$$ is cake with L'Hospital's rule. But then you lose an opportunity to talk about the squeeze theorem. Another limit (that does not require L'Hospital's rule but i...

False. Differentiable functions are locally linear.

f(x)=|x| is continuous, but near 0 is not very much linear.

user259867

Your argument could be stated a bit more precisely as sin(x) / (x + tan(x)) = (x+O(x^3)) / (x+x+O(x^3)) = (1+O(x^2)) / (2+O(x^2)) = 1/2+ O(x^2)... using Big O notation
