@Heike Migrating will require that the site at least be in public beta... I'm very certain that once it opens (tomorrow, most likely), it can be transferred. Merging the two questions is the best option here...

what happens when it gets merged is that all the new answers will be added to the old question and sjoerd's question will just be a stub

@yoda ok, thanks.

on the plus side, everyone who voted for that on SO can vote for it again =)

@Simon It's magical: I did some gymnastics, I come back, highlighting works!

Nevermind, it's broken again.

Screw magic.

@David I went for a swim and my syntax highlighting still works...

have you tried Tim's version? meta.mathematica.stackexchange.com/q/118/34

@David ;-)

Yes I did :-(

@Simon I have the same injection code as Tim. This should definitely make no difference!

@David What about installing chrome for this purpose? Afraid you don't want your Fireslowfox back?

Trololol

@David Can you go to help and post your real FF version number?

9.0.1

It really confuses me that there was highlighting when I came back.

Waiting 2 hours for highlighting to appear isn't very comfortable in the long run ;-)

Depends on how beautiful it looks.

@rcollyer What do you mean with your choices of radians etc?

When you plug -2 Pi t + Pi/2 into polar coordinates, then it's a function mapping the interval [0,1) to the unit circle in clockwise direction, starting at "12".

@David The minute hand travels $2 \pi$ radians per hour, and the hour hand travels $2 \pi/12$ radians per hour. So, I'm curious how you got your numbers.

All the calculations I made are based on minutes, not on hours. So when you call this function polar with the argument t/60, then you've got something that travels around the clock once in the interval of [0,60).

Damn, differences in units. That's what I was missing. Thanks.

I'm using the same approach as you, basically.

minutes vs hours ;-)

It's time we introduce the kilosecond globally.

(Not in the US and Burma though)

For some reason, my brain wasn't translating $\pi/360$ as traveling half-way around the clock every half-hour.

@David Of course not, that would be silly.

I'll add that as a comment nevertheless

The code for the manipulate part isn't written very clearly anyway

Just edit the post, I'll remove the comment.

removed.

@David Currently your outscoring @Verbeia even though here answer is the accepted one.

At least his one stays on top in case people actually want to learn something ;-)

(Her) Actually, I was going to post something very similar to what you posted, without the ensuing hilarity, but the solution was the same. Basic physics. So, people will learn something. You may wish to update your solving the system section indicating how you get your equation, but other than that, it's good.

<---- girl :-)

Really? When did that happen? :P

(Yes, I know: conception.)

@rcollyer that's not true for some people, but it is for me. :P

I'm gender neutral in that respect.

@Verbeia true, very true.

now there's someone I've never seen in chat before :)

Should it worry me that this is my highest scoring answer of the last few days? :x

indeed... on chat since 22 jan :) welcome @MichaelPilat

hah, hi all

congrats again on the new site

Long time no see.

Yes, I know... got busier and busier as time went on

I know how that works.

also, it was frickin' hard to find an un-answered question

How's the new job treating you?

@MichaelPilat didn't notice ... :(

@MichaelPilat heh, you were around here in the dry days when most of us weren't around

Word spreads fast! They are treating me very well

@MichaelPilat I'm only a step away from you on LinkedIn, so yeah word travels fast.

back later...

later!

@yoda I like to think I got the ball rolling =)

you definitely had a hand in it.

@rcollyer now I'm wondering who we have in common

@MichaelPilat Arnoud, Brett, and possibly Sjoerd.

Arnoud and Brett would do it

interesting that there's more people in the chat here than there ever was on SO

we were using the SO room as our "war room" while trying to get this place on the map.

so it was somewhat busy, although not as many people there.

nice

so are you going to post any questions? We're kind of jonesing here for more. :P

Seriously, it's like talking to a bunch of addicts ...

And, yes I count myself among them.

Can't say I'm using Mathematica much lately, unfortunately

you're here. which is nice. So, don't worry about it. We'll hit up someone else ... :P

hah... I will still try to answer questions when I can, I have a lot of accumulated knowledge

(about Mathematica at least)

lol

hmm, need 2 points of rep to hit 500 before private beta ends ...

What for?

Also, when does private beta end?

@David I'd like to say I had edit capability at some point. I'm the proposer, after all. :P

@David possibly tomorrow, possibly later. But, tomorrow or Wednesday most likely.

Night, all.

any news on plans to go public beta? Is it normally midday US time like the private beta launch? Anyway, I'll see what has transpired when I wake up tomorrow.

Hello @RebeccaChernoff ! When do you think we'll go into public beta?

We have both remote-access and remote-kernel. Do we need both? If yes, what will be the difference between the two?

Guys and gals: don't fret; we haven't completed the requisite seven days for private beta. On the eighth day, if we're still in private beta, you could maybe post something on meta asking why...

Just curious and excited. I don't even know when is a private beta deemed ready to go public.

Theoreticalphysics had issues with this, but it was mainly due to low number of questions being asked. (That whole expert level question thing, again.) We don't have that problem. I think are current problem is that the experts are running out of the stored up questions they had, and we need the "lesser" users to step up which is starting to happen. But, we have a tremendous amount of material, thus far.

Especially compared to any other private beta I've seen. Plus, we have at least 2 users well on their way to the 2k mark, so we're in good shape there. We're active and maintaining a high ask and answer rate (despite the recent slow down), we're in good shape to go public.

Precisely what rcollyer said. We've nothing to fear; the future is bright and clear.

They'll flip the switch in the next couple of days, and if they don't, they'll probably tell us why.

Hi @rcollyer I believe you were trying to contact me a couple of days ago, right?

@magma Possibly, but I cannot remember to save my life. Which means, it wasn't that important.

@rcollyer ok :-)

I should go. later.

is there a way (with MMA) to find out all the users of mathematica.SE and mathematics.SE who follow a particular tag? Could i post this as a question on main?

..or with some other software

@Sjoerd, You have my email ? It would be my great pleasure to organize a Lab visit, meeting with you, your wife and my Lab (Larry Maloney is the PI) !

Would we get to choose the theme for the Mathematica platform if it launch officially :-) ?

@JM I incorporated your comment suggestions in my post. mathematica.stackexchange.com/questions/573/…

I'm not too comfortable about bugs; maybe it can be bug-report instead?

@David I'm glad you found them worthwhile. :)

@500 It's mostly Jin's prerogative, but I think he's always open to suggestions.

@JM Arguably. You killed half of my jokes.

@JM but they are typically not bug reports. They are posts asking "what's wrong here? why doesn't this work?"

@JM I used to tag posts bugs on SO only after it was confirmed that it's really a bug. I think if the OP already knows that something is a bug, then s/he shouldn't post here except to ask for a workaround.

I feel bugs sort of presumes that the software's at fault... oh well.

@David Sorry 'bout that...

@Szabolcs @Simon is there a way (with MMA or otherwise) to find out all the users of mathematica.SE and mathematics.SE who follow a particular tag?

@JM that's why I only used to add this after it became certain that it was the software's fault :-) (perhaps confirmed by someone from WRI). Occasionally it's preferable to be aware of bugs. In version 6, there was a nasty bug in Tally when using custom comparison functions. I really wouldn't expect a bug in such a simple function! It was important to be aware of this so I won't get wrong results and I can work around it.

Same for the GatherBy bug MrWizard discovered

@Szabolcs I'd change "occasionally" to "always". :)

@JM I remember googling for old mathgroup posts many times just to check for a bug I remembered, and verify if I need to work around it in a newer version. On this site I'll be able to just click bugs and get all this information!

If it's indeed software error and not PEBKAC, bugs is fine. But a lot of reports look like wrong usage.

One time in math.SE, there was this guy who was complaining why he wasn't getting what he wanted from FourierTransform[]. It turns out he never knew about the FourierParameters option...

@JM There are three posts now with bugs. Two are fine IMO, while the one titled "Why does Mathematica claim there is no even prime?" is somewhat questionable

@JM I just read the answers there and it's clear it's not a bug. Removing the tag

@JM I was wrong ... this is the second mistake I made today because of rushing ... too tired. Please don't let me edit anything any more today ...

@magma I don't think the SE software lets you see who is following a tag, so probably nothing that mma can do here

@magma You'd have to look at api.stackexchange.com if there's something for this

@Szabolcs :)

@JM I did still edit the tag wiki though ... you can see the review queue

Approved.

Done for today. Later, y'all.

Capped again.

Thank you @yoda and @Szabolcs

@magma based on a quick inspection it does not seem to be possible to see who follows what. but it's possible to see who posts in what tag

api.stackexchange.com/docs/tags-on-users

@J. M. Who is Jin ? I would be happy to make suggestion. I think a slicker looker, maybe similar to Mathematica would be Awesome !

All in good time :-) we're not even out of private beta yet

@David You do realize that if the voting continues on pace, you'll likely end up with a populist badge?

@500 meta.mathematica.stackexchange.com/questions/119/…

@rcollyer Problem is people upvote the other guy

Also JM's "improvements" ruined my offtopic post and made it useful

@David :)

>This badge can be awarded multiple times.

I need to write more rubbish! ;D

@David True, but her post has to break 10 to make it eligible for the populist badge.

and, you have to have at least twice her score.

Hmm. Well, the post gets older, upvotes won't be as frequent as they are now

I still wonder why people even look at that question, I thought it was as boring as what I did

it's gold for a reason: it's hard to get.

That's why I came up with the post in the first place

boring, yes. simple to answer, yes. and that means upvotes.

That's true. Most of the interesting questions appeal to only a small group of users.

Therefore, no upvotes.

or, are only understandable by a small group of users.

those are always a pain to work with.

The questions here are pretty high level to be honest

Most people I usually talk to about Mathematica struggle with the difference of /@ and @@@

at the moment, that will change when they open the doors to everyone.

@David the difference there is somewhat subtle.

That was just an example. I could have written "They don't understand #&" as well.

as to why f @@@ {1,2,{5}} and f /@ {1,2,{5}} give different results is interesting.

@David that takes a little while, too, but I understand your point.

Most people I know use Mathematica for plotting a couple of times, and then come to the conclusion that there are better alternatives for doing that.

It's my primary visualization engine, and I'm not even that good at it.

But, it is preferable to MatLab

It took me quite some time until I acknowledged Mathematica as a real language you can program in

True, and that is when I taught it to dance.

"It's a plotting and antiderivative-finder system, yeah, it's turing complete, but so is brainfuck"

Your Mathematica can dance?

when I want it to.

Or did you simply use Dance[]

I programmed Dance[]!

:P

I actually just looked up whether there's some built-in Dance ;-)

@David But, brainfuck isn't a functional language, so what use is it?

@David lol.

Writing comments in Mathematica is annoying

Brainfuck is clearly superior.

I told my fellow students that I could make it dance, and after seeing what I learned to do with it, they agreed.

@David yes, but it's the rest of the language that hurts.

You're being irrational

No, just transcendent.

I just downloaded the brainfuck compiler written in brainfuck.

I'm still looking for the source code in the files.

:P

Haha

Okay, you have to compile it yourself, python routine is included

It even adds ASCII art to the generted program, brilliant

funny.

Wait, is that a naked woman in my source code?

Almost tempted, but no I won't download it.

Gotta go.

See you :-)

@rcollyer Oh wow, this is one brilliant example of hacking.

The compiler's source code isn't only written in brainfuck. It's also a valid program in C, Bash, and TCL.

@500 I found it at your website.

@rcollyer vote-whoring, apparently

@David brilliant.

@DavidZaslavsky seems that way to me.

(completely unintentional, I assure you)

hmm... I just realized how close we are to having a nonzero number of 2K users before the end of private beta :-)

@rcollyer @David will only get the populist badge if I have at least 10 upvotes, which I currently don't.

@verbeia Hi is David Bailey also here on MMA.SE?

magma mathematica.stackexchange.com/users not under his full name, anyway.

wow, just hit 1k

@Verbeia Congratulations :-)

@magma thanks - I just looked at the moderator tools and there is nothing to do. Everyone is so well behaved :)

@Verbeia Are you now a moderator?

@DavidZaslavsky Szabolcs has maxed out for today, and so has Leonid, and they're both about 2 days, minimum, away from reaching 2k. So, it's not likely to occur before private beta end.

@Verbeia Yes, I mentioned that.

@magma No, moderators have diamond symbols next to their names. What Verbeia is talking about is that reaching 1000 rep allows her (and other people with at least that amount of rep) to use (some of) the tools used by mods for post monitoring.
