@VitaliyKaurov Next to those two?!?! I wouldn't dare :)

(Maybe next year I'll contribute. I studied your code for that tree very closely when I first saw it.)

@VitaliyKaurov Hi, I may still need some help.

@Mr.Wizard I was going to reply to you answer, but I ran into more difficulties. Now I don't know where to put the code, without making things even more messy.

Can you explain the difference between
Unprotect@Graph
With[
{uq = Unique[]},

uq = False;
expr : Graph[___] /; (uq = ! uq) := (Print[Unevaluated@expr]; expr)
]

ue = UndirectedEdge;
Graph[{ue[1, 2], ue[2, 3]}]
(*prints*)

and

Unprotect@Times
(*Clear@Plot*)
With[
{uq = Unique[]},

uq = False;
expr : Times[___] /; (uq = ! uq) := (Print[Unevaluated@expr]; expr)
]

Times[2, 3]
(*does not print*)

?

My point was going to be that Villegas-Gayley also doesn't work nicely for nested functions. Because I could not make an example will Times work I will have to think of something else

@ManishEarth I hope you've done your homework.

That's pretty cool. I'd try to get him to sign my copy of NKS with something like "To the endless wonders of the computational universe."

"no arbitrary limits". right

selecting the files in the GUI and right clicking works just fine

rm -rf

@acl You can change the limit with ulimit

acl

@rm-rf ah!

@rm-rf can't believe I didn't know that!

anyway I've written a script with a do loop to do it, but next time I know what to do!

rm -rf

hehe

Wolfram Blog: Wolfram Year in Review: 2013

posted on January 03, 2014 by Wolfram Blog Team

Before we dive completely into 2014, we’d like to take a minute to look back on some of the biggest announcements and most interesting stories that we shared on the Wolfram Blog this past year. Below are the top 10 most popular Wolfram Blog posts of 2013, with a few honorable mentions thrown in for [...]

Is there a hotkey to insert pairs of (* *) ?

rm -rf

9:58 PM

@Rojo Command (Ctrl) + / will comment the selection, but it doesn't insert a pair by itself. As a shortcut, you can do Space + Command + /

@rm-rf @Rojo If you press Alt + / (or Cmd + /) after you typed something, then it seems Mathematica comments out the preceding expression.

rm -rf

11:40 PM

@halirutan That is correct, which is why I suggested Space + Command + /, which works on a new line :)

Rojo

Thanks people. I'm not convinced anyway. I don't particularly like that when I am adding comments to code that is already there, I have to temporarily comment the whole thing

So I hoped it worked in "used" cells. Furthermore, beginning with the selected (* *) isn't the same as having the crusor in the middle

halirutan

@Rojo You are right, excellent is something else..

Rojo

@halirutan Guess I'll have to remove the dust from AutoHotKey

halirutan

@Rojo If only I could think of an editor which does it exactly the right way....

Rojo

@halirutan Haha
