@robjohn well, that would depend on what tab is currently selected. It could've been on "active", which wouldn't have shown him if he wasn't
 
12:35 AM
@Verde Not really; I was asking "I'm here; what do I do now?" :)
@robjohn Quite peculiar. I don't know if anybody other than balpha and maybe Marc is doing the tweaking...
 
acl
@verde thanks, yes, I should have searched! That looks useful
@j.m. (I guess you won't be notified but I am on an iPad) no I had not, I started reading up today so am collecting references
 
@acl I was, amazingly enough. :)
See their bibliography, too.
 
acl
@j.m. Yes, I'll hopefully locate it in the library tomorrow, hurl it at my collaborator and hope he survives. Thanks!

Lol, I'm kinda surprised that a timing comparison answer outvoted other actual answers...
but then, I'm in academia and am not a stranger to review articles getting 10x more citations than the original works =)
 
@R.M Apparently, people like all their results in one place. :D
 
acl
@j.m. Notified? (has the notification system changed?)
 
@acl Yep. (Thank balpha and the others coding up the chat.)
 
acl
@j.m. That's nice! Ok, off to skim the references you and @verde gave (thanks again, that book seems very clear)
 
1:12 AM
@J.M. Let me check now (sorry I got a call from my boss, so I had to go afk for a while)
@R.M I was selecting "all" and sorting by reputation (he would be very near the top then)
He's there on page 10 if you don't put any filter in
 
R.M
1:40 AM
@robjohn aha! I think it's related to chat.se's old bug of not including 2 letter names. They fixed it in the pings, but not in the search
 
@R.M But I know that a while ago I was able to find J.M. and t.b. in that same way.
So I figured that it had been fixed in chat, too.

@acl: good idea!

I am trying working on Problem 39 of Project Euler,you can see it here projecteuler.net/problem=39 .I use IntegerPartitions, but code turns out to be as slow as snails, more than one minutes!!! could you anyone give any advice?
@Rojo I don't know how to @ more people at once, I need your guys help.
This is my ugly code:
Last@Sort@
Table[{Select[
IntegerPartitions[
i, {3}], #[[
1]] < #[[2]] + #[[3]] && #[[
1]]^2 == #[[2]]^2 + #[[3]]^2 &] // Length, i}, {i, 1,
1000}]
 
11:22 AM
Try Count[IntegerPartitions[900, {3}], tri_ /; First[tri] < Total[Rest[tri]] && Norm[Rest[tri]]^2 == First[tri]^2].

Consider a question like this; it would make sense to ask for more details, since it's hard to guess what the problem is from the error message. But, if I post a comment "please include details", most likely there will be an 8K codedump as seems to be the norm these days.
should we not have some standard comment, along the lines of the greeting comments, for this purpose?
 
3:20 PM
@acl Always Scylla and Charybdis...
@acl You're gonna write one? :D

@R.M Didn't know that. Thanks for the tip!

Q: Can we get the twitter bot to tweet to #mathematica?

R.MThe @stackmma twitter bot tweets certain questions (algorithmically determined) and converts the first tag (sorted by number of questions) to a hash tag. Hash tags are twitter's way of sorting things and the article says: People use the hashtag symbol # before a relevant keyword or phrase ...

@StackExchange you're slow, aren't you?

@R.M You shouldn't defy the powers that be
 
11:20 PM
@paradox2, perhaps Transpose[IntegerPartitions[900, {3}]]^2 /. {a_, b_, c_} :>
Length@a - Total@Unitize[a - b - c]
Hey @Verde
Just saw your old ping
 
I don't remember why I pinged you
 
I came up with a funny way to transfer mma code from SE to mma. Curious what you think of it. But first, off to bed.

A: Is there a way to facilitate the copy&paste process for code samples?

Sjoerd C. de VriesWell, I have come up with something slightly different. Please tell me what you think about it and I'll elaborate on it. The basic idea is the following. Below you see a picture with some code in it (a piece of mr.wizard's code from here). It's apparently an inert picture and normally you couldn...
