@StephanLehmke: Temporal logic is used a lot by a few guys from Software Engineering to build concurrent models. :)

OMG @MarcoDaniel is here! :)

Hungry! I am going to prepare Maggi. :)

I'm more of a fan of Petri networks. :)

@kan ooh food!

@kan According to en.wikipedia.org/wiki/Maggi "In India, Maggi instant noodles are a favorite for an anytime meal. From dorm rooms of colleges to late-night cooking in home kitchens, it's an all-time favorite."

@JosephWright: can you please zap this message? chat.stackexchange.com/transcript/message/7084027#7084027 It's conceptually wrong, I was just kidding. :)

@PauloCereda Yeah and I am a new fan of these songs: youtube.com/watch?v=Pwe-pA6TaZk and youtube.com/watch?v=zlfKdbWwruY

@egreg Maggi is delicious. :)

@egreg Ah! Yes. :)

I missed my dinner, hence.:( (Don't look at what time it is in India).

@MarcoDaniel Awesome! Where's Brazil? :)

@kan I was a bit puzzled, seeing you around. :) Do you ever sleep?

@PauloCereda Never got the hang of those. But then I've never been interested in timing issues ;-)

@StephanLehmke I had to work with an adaptive model of those. Then things got really scary. :)

@PauloCereda Graph-structured formalisms are always a pain...

@StephanLehmke They are. :) But I love'em! :)

@StephanLehmke: The paper I submitted on semi-automatic layout generation was based on automata. :)

The reviews will be sent any day now. :)

@PauloCereda Thumbs up! My student is just putting the finishing touches on his work using genetic algorithms.

@StephanLehmke I'm eagerly waiting to read his papers. :)

For something completely different, Dortmund (late national champion) is playing against Munich (record national champion) tomorrow. After having been outstanding in champions league and mediocre in national league, there is a lot of suspense how Dortmund will perform...

@StephanLehmke Will you go watch the game? :)

@MarcoDaniel Found it: Rio de Janeiro, first video. :)

@PauloCereda Going to the stadium is not really my cup of tea, though my father and my daughter (and a lot of colleagues) love it. I've never been in Westfalenstadion ;-)

@StephanLehmke When I'll visit Germany, I'll definitely go to a stadium. :) Probably watch Dortmund or Bayern. :)

@MarcoDaniel: are you still around? :)

@egreg I definitely do. Just that some days are more productive than the others. :)

@PauloCereda for some minutes ;-)

@MarcoDaniel Take a look at our shared folder in Dropbox. :)

a question for TeX.SX or GD: CDF derivative of pdf? How does this work?

someone should write a pdf2cdf utility :D

@PauloCereda mp3 version ;-) I did the same ;-)

@MarcoDaniel Germans. <3

Just used {\ifnum0=`}\fi and \ifnum0=`{\fi} in an answer. ;-) But David is not here to comment. :(

@StephanLehmke: can I send you an email later on? :)

@PauloCereda Of course. My email address is in the profile.

@StephanLehmke Danke. :)

Have to go home. Bye.

See ya, Stephan! :)

And got a green tick by an answer like this: "You can't do it".

@egreg :)

@egreg Have you come across this kind of "normalisation"? A vector in ℚ^4, for eg, (0, 2, 3, 4) being "normalised" to: (0, 1, 3/2, 2)... that is, the vector, being divided by its first non-zero component.

@kan Not that I remember.

@egreg Ah, OK. :)

@kan It's what's done in Gauss-Jordan, however.

@egreg Yes, to reduce to the reduced rwo echelon form. :)

@kan: in other news, how do you like my recursion attempt? :)

@PauloCereda Did I miss your code?

@kan chat.stackexchange.com/transcript/message/7073790#7073790 :)

@PauloCereda Oh! Wow!

Why didn't I think of this? :(

@kan Been there, done that. :)

As I said before, prefer your iterative code. :)

This recursion thingy is just for practice. :)

This is a very good technique, actually.

@kan You mean, recursion?

Writing a function and passing the list itself!

@kan Ah. :)

@PauloCereda No, I mean, your implementation of recursion...

You have an exercise for me, now? :)

or, well, for the reader, anyway. <3

@kan You may rest now. :) You've been a good aprentice. :)

@kan: IMHO we only learn to write good code with time. :)

Well, time is definitely a parameter, but only one of the several parameters. For instance, I believe in looking for opportunities where you can write some code...

@kan time measured as "time spent coding"

@tohecz even then! perhaps, I am being misunderstood. By coding, I mean "Real" coding, well "Complex" coding or whatever.

@percusse Are you really suggesting to use PP instead of beamer? ;-)

@PeterGrill I don't care much about the arrows, but I'm wondering if there's a less kludgy way to have the arrow from T to C avoid the VP structure? (Other than adding the temp node manually.)

@AlanMunn I was not sure from the question if the OP cared. But, I don't know tikz-qtree so can't comment on the rest...

@PeterGrill No, I realize that, but what I'm asking you has nothing to do with tikz-qtree but with tikz more generally. So is there any way to specify a way to draw between two nodes and avoid some other part of the drawing?

@AlanMunn Oh, let me have a look...

@AlanMunn Ok, I see one minor improvement: You could draw it all in one step: \draw [-latex](T.east) |- (tmp.center)-| (C);

@PeterGrill But there's no way to avoid making the tmp node manually?

Other than that I do recall there was an interesting question on here about drawing lines that avoided objects, but I don't know a better way.

Here is one link, but I recall a different diagram: tex.stackexchange.com/questions/27899/…

@AlanMunn You could always use tex.stackexchange.com/questions/55068/… I guess, but then the distance would have to be specified manually.

To all the mods : Can we also invoke a message similar to this one?

@AlanMunn Oh, you could use \draw [-latex](T.east) |- (current bounding box.south)-| (C);

I mean the We're looking for long answers that provide some explanation and contex... part

@egreg Why not giving MS another chance ? Go on then... You know you'll like it. :P

@TorbjørnT. :) It's always fun to see your own questions quoted at you! Thanks, Torbjørn, I'd forgotten about that one.

@PeterGrill Cool. That works really nicely. It's not really a general solution since it's only an accident that the structure to be avoided is at the bottom of the whole picture. I'll add a comment about doing it that way in this particular case, but the tmp node solution for the moment is more adaptable to other situations.

@AlanMunn Not sure if there is an easy general solution. I guess you could use the fit library to define new nodes that you want want to avoid and go around then. But that still requires a temp node to be created.

@AlanMunn Also a small twist :P
    \draw [-latex](T.east) |- (current bounding box.south)-| ([yshift=-1.5mm]C |- DPt1) arc (-90:90:1.5mm) -- (C);

@PeterGrill Right, that's what I thought about, but it seems more effort than it's worth.

Bah whatever SE , you win :)

@percusse Sweet!

@AlanMunn Instead of a temporary coordinate you can use a relative coordinate via |- ++(x,y) or |- ++(240:3cm).

or even south of diesen film label.

@percusse What would be the syntax of the south of version?

@AlanMunn Ah so that doesn't have a node name I guess. (I'm not too familiar with it), is it a node label?

@percusse No, it's named Obj but I still couldn't figure out the right way to substitute the (++240:3cm) with something involving south of Obj.

@AlanMunn Oh it can be something like |- ([yshift=-1cm]Obj.south)-|

@percusse Perfect. I like that solution best of all. It's much more general, and it allows you to avoid the structure in a way that is sensible with respect to the tree nodes themselves. I'll update the answer.

@AlanMunn In 10 mins I can upvote, heheh
