12:00 AM
@Guillochon Mma performs weird sometimes :)
 
@Guillochon Have you heard of/used LevelScheme?
 
@Hypnotoad I have heard of it, but haven't tried it
@Hypnotoad It looked a little intense
 
@Guillochon and gives you warts
 
12:15 AM
@Guillochon Well, it can be a bit overwhelming at first, but I've found it simpler to use especially if you have complex gridding. Of course, it can be done with Graphics/Grid/Row/etc., but I can never seem to remember the paddings and spacings that need to be fiddled with
This or this might be a starting point for those interested in using LevelSchemeHypnotoad yesterday
 
Nice :) You can soon start voting to delete right away
 
almost there
 
OK, really dumb question...why do Grid and Column behave differently?
For say a 1x2 grid (which is a column)
 
@belisarius wait... are you using mma as a poor-man's image cropper?
 
12:25 AM
@Hypnotoad Meh? Nah! I'm rich
 
@Guillochon What do you mean by "behave differently"?
 
Grid needs {{ },{} } ...
 
Right
But I'm saying that Grid[{{},{}}] and Column[{}] render slightly differently
 
@Hypnotoad and uploader :)
 
The difference is the amount of spacing between items, even with Spacings -> 0
First with Grid, second with Column
 
12:29 AM
@Guillochon Your plot looks like the silhouette of a red haired samurai
 
@belisarius I wish I could drive a katana into the computer sometimes...
 
@Guillochon They have different underlying base styles... that could be the reason.
DeleteCases[#1~Join~#2,
   Alternatives @@ Intersection[#1, #2]] & @@ {Options[Column], Options[Grid]}
I can't say much more without digging into it...
 
OK, that's fine. Good to know that there actually is a difference.
 
The boss coming in at the end is the best part
 
12:38 AM
yup
 
What is the default styling of FrameLabels?
 
@belisarius did you have a chance to try the notebook?
@Guillochon TraditionalForm
 
@Hypnotoad Hmm, can it be applied to something that is already in another form? Trying to use this on a DisplayForm object
DisplayForm@
RowBox[{SubscriptBox["Log", "10"],
OverscriptBox[StyleBox["M", FontSlant -> Italic], "."], " ", "(",
SubscriptBox["M", "\[CircleDot]"], " ", SuperscriptBox["yr", "-1"],
")"}]
Oh nm
Got it
 
@Guillochon Don't work directly with DisplayForm objects unless you absolutely have to...
 
12:44 AM
OK, how would you recommend I put that in traditionalform?
 
Just use strings for the labels and use subscripts/superscripts, etc as you normally would (with Ctrl-6, etc.)
 
@Hypnotoad Sometimes Mathematica cannot do the italicizing right when you do it that way
 
You might have to set SingleLetterItalics to True
 
Hmm OK...well anyhow, it looks like actually this isn't working out for me to put things in TraditionalForm, when I put it in a Row, it reverts back to DisplayForm
Row@{TraditionalForm@
DisplayForm@
RowBox[{SubscriptBox["Log", "10"],
OverscriptBox[StyleBox["M", FontSlant -> Italic], "."], " ",
"(", SubscriptBox["M", "\[CircleDot]"], " ",
SuperscriptBox["yr", "-1"], ")"}]}
 
Isn't something like this what you want?
 
12:50 AM
yes
 
You can see the string I used
 
Oh, sorry...I didn't look close enough at your plot, it's the same plot I had before, i.e. two plots stacked on top of each other
But I want the y-axis frame label in the middle
So basically I wrapped that in a row, and put the rotated label to the left of the stacked plot
It would be fine if it would just stay in TraditionalForm
 
But that wasn't your question... you asked about traditional form and such and how to style it
 
Right, the label doesn't remain in TraditionalForm when I wrap it in a Row
Which is what I think I need to do to get the label I want
 
Try: Style[Row[{Spacer[200], "string"}], FontSize -> 15] You might have to manually adjust the Spacer value for now. It's possible to do it programmatically, but you can figure that out... also, if it's a one-off thing, no point in digging in right now
 
12:55 AM
GraphicsRow actually seems to work to keep it in TraditionalForm, but it adds massive padding around it for some reason
Style seems to make it not be in TraditionalForm
 
1:12 AM
Ugh, nothing I try is working here
@Hypnotoad I've *almost* got it, can you tell me why this command produces so much whitespace: Graphics@Text[
DisplayForm@
RowBox[{SubscriptBox["Log", "10"],
OverscriptBox[StyleBox["M", FontSlant -> Italic], "."], " ",
"(", SubscriptBox["M", "\[CircleDot]"], " ",
SuperscriptBox["yr", "-1"], ")"}]]
Ah, success! Had to include an ImageSize option.
 
2:01 AM
Could this be shorter?

A: "Sorry, young man, but it's Turtles all the way down!"

belisariusMathematica 200 198 188 171 168 Spaces added for clarity: f[i_, b_, h_, j_, r_, n_] := (a = h; p = j; s = k = {}; t = Flatten; (Switch[#, 6, s = {a, p, s}, 8, {a, p, s} = s, _C, k = {k, Line@{p, p += {Cos@a, Sin@a}}}]; If[# < 9, a += I^# b ]) & /@ t@Nest[# /. r...

 
2:35 AM
@belisarius You can maybe transform the If
Comparing this
a = 0;
If[OddQ[#], a += #] & /@ Range[10];
a
and this here
a = 0;
OddQ[#] && (a += #) & /@ Range[10];
a
you spare one letter ;-)
 
3:15 AM
@halirutan One more if you do Range@10
oh, wait... that probably wasn't part of the solution.
 
@Hypnotoad It was only an example.
@Hypnotoad yup.
 
Helloo
 
hello
In 10 days, it's the site's 1yr anniversary :)
 
@Rojo Hi.
@Hypnotoad Question: When you rename yourself so often, what happens to all the @rm-rf in the comments? Are the renamed appropriately?
 
@halirutan Nope
The renaming started as a joke, but as with all things ... :)
 
3:31 AM
@halirutan You could become rm-rf now, for the sake of the orphan comments
 
lol
 
@Rojo That's an idea to think about.
 
And I'll become halirutan. Please also handover your github account =)
 
But @Hypnotoad, you changed your name initially because there was another "R.M." or "M.R.", was it?
Or just for fun?
 
@halirutan That was a consideration, but no... I made it a cursive RM, but people complained that they couldn't ping me. Then I made it rm -rf just as a play on the initials. The present one was purely for fun
 
3:34 AM
I liked the rm -rf the most.. Wouldn't be formatC the logical name?
 
Actually, it was when someone asked me (a few days ago) why this chatroom had a strange and weird fascination for toads that I decided to change for fun
 
ah
 
@halirutan Yes, that was my favourite one too :)
I'll change it soon to either rm -rf as before or rsm to match my bitbucket account.
And kill the toad once and for all
SE should automatically insert the userid instead of the name in comment pings... that way, everything is uniform.
 
@Rojo @Hypnotoad Btw, and apropos GitHub. I found a bug in the autocompletion-code not related to the algorithm. When I set up the functions in the Kernel/init.m, the code is executed when the kernel starts up and at this point the FE has not been started. Therefore, the functions I redefine FE`FC... do not exist. It works anyway, but is there a better alternative than putting it into Kernel/init.m?
I looked at Frontend/init.m but this consists only of option settings and not of real code.
Maybe in the Autoload folder?
 
@halirutan This is only for a fresh mma session, right?
At what point is the FE started?
For some reason, I always thought that the FE was started first
 
3:47 AM
@Hypnotoad Hmm.. I don't now.
@Hypnotoad I found this out because I have a Recover function
which saves the DownValues of the original functions. Those where empty when I put the stuff inside init.m
@Hypnotoad Now that you say it, I find this very odd too. When I kill and restart the kernel, then the FE is up.
 
4:06 AM
@halirutan haha thanks :)
@Rojo Hi dearest neighbor
 
@belisarius Hey
How's all going
 
4:47 AM
@Rojo quite well, right on the fence of the 20k, then I'll take a rest
@Rojo are you awaken, asleep or alive?

Do we have any function that work ParallelTry in sequentional form, to Apply the GCD to a list and once a result of >1 is found, it aborts and return False. Apply[GCD, list] will try all values

Q: Is it a good idea for established users to change their usernames?

Oleksandr R.In the course of events, a number of users have changed their usernames--some more than once. Here I'm not referring to changing the automatically assigned username into something more personal, but rather the situation of an already established user suddenly choosing to go by a different name. ...

@halirutan I think you mean that when the kernel executes its init.m file, not all of the front end bits have been loaded into the kernel, yet. I haven't looked at this in a while, but yes, I recall that there are some annoying sequencing issues here. Yes, I think you might have better luck with an Autoload package, but I haven't tried it to say for sure.
Incidentally, in the upcoming 9.0.1, some of the behind-the-scenes stuff for completion is changing. It's going to invalidate a few answers, like the one for camel-hump completion. But there are a number of improvements and bug fixes. But no camel-hump completion (yet).

1:39 PM
@belisarius Now I'm alive
Got to 20k yet?
 
@Rojo yup, I pushed up myself the last 2 rep points accepting an answer :)
 
@belisarius Nice move
Now you'll take a break?
 
1:55 PM
@belisarius Congrats :)
 
@Rojo @Hypnotoad ... thanks :)
@Rojo don't know yet
 
@belisarius You know rm is planning to kill the toad, right?
 
2:46 PM
@Rojo I found it isn't a toad
 
@JohnFultz Will the update of 9.0.1 be after the 26.02.2013? (I plan to give a talk about the camel hump stuff.)

So. We’ve torn through the advent calendar, tossed aside all the wrapping paper, and (hopefully) obsessively screencapped our gravatars wearing various kinds of silly hats. As of last Friday, Winter Bash 2012 is officially over!

This event was awesome. We had a total of 46,710 users participating across 76 sites, and we gave away 108,924 hats total. The most common hat was the And I Feel Fine hat, which 23,171 users earned for activity on December 21st. The least common hat earned was I Do Say, which was obtained by Bohemian, on Stack Overflow, and kalina, on Arqade for posting an epic 30 …

The physics involved in simulating galaxy collisions can be extremely complex. The most accurate simulations take into account not just points representing stars, but also magnetic fields and invisible dark matter, as well as n-body interactions allowing the individual stars to interact with each other. These complex simulations are usually carried out on large-scale supercomputers [...]
