Perry the Platypus, also known as Agent P or simply Perry, is an anthropomorphic non-talking semiaquatic, egg laying mammal of action platypus from the animated television series Phineas and Ferb. Perry is voiced by Dee Bradley Baker and created by the series' co-founders, Dan Povenmire and Jeff "Swampy" Marsh. He first appeared along with the majority of the main cast in the pilot episode "Rollercoaster." Perry is featured as the star of the B-plot for every episode of the series, alongside his nemesis Dr. Heinz Doofenshmirtz. Perry is the pet platypus for the Flynn-Fletcher family, and is perceived...

@PauloCereda check out Microsoft's subtle product placement... lol

Adam Liter

Thanks for the suggestion, @PauloCereda :P

Paulo Cereda

@PaulGessler LOL true. :)

@AdamLiter Of course, @DavidCarlisle is a TikZ expert too. :)

Adam Liter

@PauloCereda Haha!

@PauloCereda What?! Where?

Paulo Cereda

@PaulGessler They showed him in the stadium!

Paul Gessler

@PauloCereda damn, I missed it

Paulo Cereda

@PaulGessler Of course, I was paying attention to Adriana Lima. <3

Pepsi logo?!

wooohooooooooooo

Damn no topless. I'm disappointed.

She's riding a golden sabertooth tiger. What the duck.

Paul Gessler

Is that the TeX Lion?

ctan.org/lion

Paulo Cereda

@PaulGessler LOL I thought the same!

ooh there are four ninjas in the tiger!

Paul Gessler

1:13 AM

@PauloCereda LOL

Paulo Cereda

booo Lenny Kravitz.

What the duck is happening.

LOL EPIC SHARKS

Paul Gessler

wut

Paulo Cereda

@PaulGessler look at dat shartk!

BEST. DANCE. EVER.

There are two dancing sharks on stage.

And some crazy singing trees.

Paul Gessler

and dancing beach balls

Paulo Cereda

LOL

Oh no, that guy again.

The duck...

Who's that "lady"?

Paul Gessler

1:21 AM

@PauloCereda no idea, actually. lol

Paulo Cereda

@PaulGessler haha

Look, she has a wiimote!

anderstood

Hi there :)

Paul Gessler

@PauloCereda Wii bowling later on in the show, I think

Paulo Cereda

@anderstood: Hello, welcome! :)

@PaulGessler LOL

Oh my!

anderstood

@PauloCereda Thanks, my first time on SE chat^^

Paul Gessler

1:22 AM

@anderstood welcome!

Paulo Cereda

@anderstood Ah make yourself at home! This is the most friendly chatroom of the entire SE universe. We are the TeX.sx community, but we talk about virtually everything in here. :)

Specially ducks and cricket. :)

Now we are doing a live commentary on the Super Bowl thingy. :)

anderstood

@PauloCereda Haha thanks, that very kind. I was guessing you were talking about something live. Still have some work to do :/

Paulo Cereda

@anderstood :)

I have no idea of how American Football works, so it's being fun. :)

anderstood

No Asymptote freaks here by any chance ? :D

Paulo Cereda

Hey bring Katy Perry back!

anderstood

1:24 AM

Is she playing on the field?

(that was a joke)

Paulo Cereda

@anderstood Not anymore. The halftime show has ended.

Ah. :)

anderstood

(no a very good joke...) lol

Paulo Cereda

@PaulGessler: Missy Elliott.

Whoever she is. :)

anderstood

I remember seeing a concert of Prince for the SB (on the internet); great show!

Paulo Cereda

@anderstood Cool. :) I remember Madonna and a couple others. Personally, I think the older shows are better.

anderstood

1:27 AM

Just a question before I leave: are there some chatrooms dedicated to help (not for now, but another time)? It's not very clear for me how it works here...

@PauloCereda I don't really know about the older shows, but I prefer older music^^ Except in jazz, there still are some living killers :)

Paulo Cereda

@anderstood We are kind on helping people and answering questions in here, but if it's something more ellaborate, we suggest people writing MWE's and posting questions in the main site. :)

anderstood

@PauloCereda I see. There something I'd really like to do, I spent about 10 hours on it this week-end for nothing... But it's about asymptote, so there not many specialists here. Cf. tex.stackexchange.com/questions/225461/… I'll just wait... :)

Paulo Cereda

@anderstood Oh I see. We have a couple of Asymptote specialists, maybe it's a matter of time for them to find and answer your question.

anderstood

That's the problem with SE: you get answers most of the time, so when you don't you feel lost! :D

Paulo Cereda

@anderstood In the worst scenario, @DavidCarlisle will provide a picture mode solution for you. :D

anderstood

1:32 AM

@PauloCereda a picture mode? With pgfplots?

Paulo Cereda

@anderstood picture mode itself. :)

anderstood

@PauloCereda wow no clue what this means :D I'll google it.

Thanks for you warm welcome and help. I'm staying logged in just for fun, but have some stuff to do. I might come back later, not sure.

Paulo Cereda

@anderstood ;)

Paul Gessler

@PauloCereda oooh they just mentioned rugby!

Paulo Cereda

@PaulGessler Oh no! :)

Guys, I travel to SP tomorrow, so I need to go now. Time for some sleep. :) Good night, friends!

Paul Gessler

1:39 AM

@PauloCereda good night!

yo'

@PauloCereda night!

Paulo Cereda

So the Tom Hanks bloke won the thingy. :)

It seems to work! I'm impressed of how many tricks you know!!! — user126154 16 hours ago

@DavidCarlisle: ^^

egreg

@PauloCereda Leaving for SP or already on the bus?

Paulo Cereda

@egreg I'll leave in 5 minutes. :) I have a ride today, yay! :)

Time to go, I'll be online later on via 3G, hopefully. :) You guys have a great day! :)

David Carlisle

@PauloCereda I watched the first quarter then gave up and went to bed, did anything interesting happen later?

Paulo Cereda

11:50 AM

Flood, flood, flood! Heeeeeelp!

Paul Gessler

@DavidCarlisle @PauloCereda thought Katy Perry was interesting

American culture can be... eh, how to say... interesting at times. :-)

yo'

12:17 PM

@PauloCereda what?

egreg

@DavidCarlisle Why is the originator email not hidden in your reply to the bug report?

@DavidCarlisle Please, remove it ASAP.

Joseph Wright

@egreg Oh no, not Gnats!

David Carlisle

@egreg I'll check with Rainer, Not sure why it didn't go probably gmail had quoted my reply in a format gnats didn't expect, normally it hides such things. I couldn't see how to edit that with the access I had so I flipped the entire report to confidential for now. So you shouldn't see the email address (or anything else)

@ChristianHupfer Wie geht's?

Christian Hupfer

@PaulGessler: Ganz gut ... you do know a little bit of German? surprised

@PaulGessler: And you are awake after Super Bowl Night? ;-)

David Carlisle

@egreg @JosephWright OK fixed I think. I made it public again.

Paul Gessler

@ChristianHupfer ein bisschen. 3 years in high school and a trip to Switzerland/Germany. But I have not kept it up at all

@ChristianHupfer yes, no partying for me. Got snowed in and was working on TeX projects/chatting with Paulo/watching the game simultaneously. :-)

Christian Hupfer

@PaulGessler: Keep it up, keep it up, it's more important than Portuguese @PauloCereda :-P

@PaulGessler: Some of my students missed lessons this morning since they watched the Super Bowl (being broadcast about 4 o'clock here in Germany ;-))

Paul Gessler

@ChristianHupfer oooh, bad students! Do lots of people watch it in Germany? I always get the impression that American football is not so respected/popular elsewhere. :-)

Christian Hupfer

3:17 PM

@PaulGessler: I can't say for other countries in Europe for example, but in Germany it's not as popular as such other mass sport activities... like Chess ;-)

@PaulGessler I think it has been deleted :p

6:58 PM

To anyone interested: the Engineering site just went to public beta!

moose

Findally my good symbol classifier is online :-) write-math.com/experimental

yo'

7:20 PM

@moose with [Math Processing Error] everywhere ... :)

Paul Gessler

@yo' @moose I didn't get any [Math Processing Error] but after a few rounds of Submit/Clear, the whole thing just went blank, for me at least.

Had to reload to get it back

yo'

@PaulGessler I get them instead of like 20% of symbols :-/ and I get a lot of unrecognized TeX commands, too (those black boxes with TeX code in them)

Paul Gessler

Hmmm, for that input (more jittery though... :-) ) I get

moose

7:41 PM

@PaulGessler I noticed that, too. I don't know what the problem is. Probably mathjax doesn't know these command?

Torbjørn T.

@moose There's a list of supported commands in MathJax at docs.mathjax.org/en/latest/tex.html#supported-latex-commands

yo'

@moose well, MathJaX doesn't know the ones that are in the black box, but the red ones are just who-knows-what, and they show that MathJaX is unreliable. I have a standard FF 35.0 on linux, no strange extensions, javascript allowed etc.

moose

@yo' Hmm... I currently don't know what the best solution would be. I have rendered SVGs for each symbol, but that would probably increase the time. And I don't really know if it would be worth it. The LaTeX code gets displayed and I think that is the important part

Paul Gessler

@moose maybe there's a way to detect if MathJax dropped the ball and fall back to SVG only in those cases? FWIW, I'm on an updated Google Chrome; no crazy extensions.

moose

Yes, that is probably the best solution. I could also add a link "More information" which gives additional information to the symbol and a SVG image.
Here is an example: http://www.martin-thoma.de/write-math/symbol/?id=82

I plan to give much more information there. For example, people should be able to edit this just like tag wikis on StackExchange and there should be links / a counter to publications which used the symbol for which meanings.

For example, for \alpha this could look like
* Momentum for neural network learning: 42 papers (see list)

Johannes_B

7:51 PM

If i did understand the changelog correctly, this should work:

\documentclass{article}
\usepackage[ngerman]{babel}
%\usepackage{ngerman}
\usepackage{hyperref}
\begin{document}
\fbox{%
	\parbox{2cm}{%
		das is \href{link.de}{blind"-text}%
	}
}
\end{document}

moose

Those symbol pages will have the LaTeX mode (textmode, mathmode or both) and the package (if any)

Paul Gessler

@moose the link solution could be good too. I have seen that on many unicode glyph pages: sometimes my fonts don't have a particular glyph, so I just see a rectangle. But I can then click on some "more info" or "view symbol" link to view an image-based representation of the glyph.

yo'

@moose honestly, what I love about detexify is that it gives you the package instantly. Many symbols are in multiple packages and I naturally want to choose the one that I already load.

moose

I will try to implement both as soon as possible. The link solution is a little bit more tricky than it might seem at a first glance; it might take a while to fix it.

Thank you for your feedback!

I didn't work much on the design; much more on the recognition. I will try to find a good alternative.

(Detexify has a pretty clever system when it comes to the images, but I am not sure if I really want to use the same. It has all images on one sprite and shows you only the correct part of it.)

I could use a similar design like the one detexify uses. However, I want to go as fast as possible to formula recognition and then I will have to think again about the design.

yo'

@moose typical 24x24 bw PNG is quite small, about 600B. Depending on your server, it shouldn't add too much to the page. You display ~10 symbols, that's 6kB

David Carlisle

8:32 PM

@yo' mathjax update to 2.5 can cause that until you clear your cache if you have some of 2.4 cached but then start to pick up 2.5

yo'

@DavidCarlisle ah ok, Ctrl+F5 helped, thanks :)

David Carlisle

@moose are these single symbols? why do you need mathjax for that, that's an awful lot of math layout code you are not using, all you need is a unicode code point and a big enough font don't you?

@yo' @moose there are 32x32 pngs of all the math and latin/greek/cyrillic/arabic ranges here w3.org/2003/entities/2007doc/000.html (along with direct unicode character rendering of same slot)

yo'

@DavidCarlisle well, these are 1bit, they should be down to < 300 B

David Carlisle

@yo' some of the newer ones are greyscale but yes we were pretty agressive originally (those pages used to take several minutes to load over dialup:-)

yo'

@DavidCarlisle :)

David Carlisle

8:41 PM

@yo' we were told to put a warning in the page that links to those pages as they were considered rather antisocial due to bandwidth use when mathml 1 was first being reviewed. the warning is still there:-)

egreg

9:03 PM

@JosephWright If I try with \tl_upper_case:n, then \\ disappears.

moose

9:23 PM

@DavidCarlisle Hmm ... right. So you suggest I should remove MathJax and instead show load something like "∫" for the integral sign. But do the symbols look like they do when they are rendered with LaTeX? Do I have to set a font (which one?)

moose

9:40 PM

How could I for example display \leftmoon of wasysm? "texdef -t latex -p wasysym leftmoon" tells me it is defined as "macro:->\mbox {\wasyfamily \char 36}" but how should / could I use that to display it on a web page?

David Carlisle

@moose well it depends if you need to display formulae or just single symbols. If it is just the latter then you can specify say stix as a web font and just use that uniocde slot, that's all mathjax is doing once it gets to teh character level, and teh rest of it is parsing tex syntax and laying out complicated layouts and you don't seem to need either

@moose that won't work in mathjax either. it is not magic, it can only use fonts that are available either installed locally or as web fonts

@moose does it have to be wasy font? unicode-math says \leftmoon is unicode U+263e so you could just use that characater with stix or another unicode font

@moose like so: ☾

@egreg a bug? Obviously not my code! where?

Joseph Wright

@DavidCarlisle Not really a bug

egreg

@DavidCarlisle No, it's clearly a feature!

David Carlisle

@JosephWright what was the context though? @egreg just said "it" :-)

egreg

@DavidCarlisle Joseph knew what I was talking about. Are you feeling excluded?

David Carlisle

9:50 PM

@egreg yes

@egreg similar to when @PauloCereda and other American football experts were chatting last night.

egreg

@DavidCarlisle Well, it can't be so different from cricket: there are 11 players. But in American football they're all in and nobody's out, except for a concussion.

David Carlisle

@egreg thanks, that's clarified things. I'm sure next year I'll have a better grasp of what's going on.

egreg

@DavidCarlisle Of course the players don't use bats. Their hands and arms are sufficient for the purpose.

Joseph Wright

@egreg Another of the open questions: how to handle control sequences. Currently we have \exp_not:N but I'm not sure it's the right way to do things.

@egreg, @DavidCarlisle Thus-far I'm a bit light on feedback on the case change stuff!

egreg

@JosephWright Well, expanding unconditionally doesn't seem like a good idea. But when dangerous macros are \protected, it should be easier.

Joseph Wright

10:00 PM

@egreg Well yes, but then we have the question of what constitutes 'text' in these cases, etc. We could drop the \exp_not:N and say that people should use \protected@edef for 2e forced expansion.

egreg

@JosephWright Text is what's unprotected.

@JosephWright Unless you'd like to examine every macro to see what it does.

Paulo Cereda

@DavidCarlisle You could talk about Katy Perry. :)

Joseph Wright

@egreg I meant 'What are the semantics of the argument to \tl_<type>_case:?'

egreg

@JosephWright For me, words, or things expanding thereto.

@JosephWright But of course, things like \\ may creep in.

Joseph Wright

@egreg Rather my point :-)

egreg

10:09 PM

@JosephWright That's why I'd like there was an “all caps” font shape.

Joseph Wright

@egreg Doable with LuaTeX

egreg

@JosephWright So let's go LuaTeX. :-)

Joseph Wright

@egreg Well yes

@egreg Problem is people have an idea of 'make this text all upper case' in a programmatic sense

David Carlisle

@PauloCereda didn't see her

Paulo Cereda

@DavidCarlisle She was riding a TeX lion. :)

Paul Gessler

10:16 PM

@PauloCereda I was informed today at work that it was actually a tiger (think of the song lyrics :-) ) but whatever

It was the TeX big cat

Paulo Cereda

@PaulGessler ooh big cat!

David Carlisle

Paul Gessler

What do you think its catcode was?

yo'

In the jungle, the mighty jungle, the TeX Lion sleeps tonight...

David Carlisle

@PaulGessler 9 in my case

Paul Gessler

10:20 PM

@DavidCarlisle :-) (I had to look it up, I only know 11 and 12 by memory...)

yo'

@PaulGessler I'll guess: ignore

Paul Gessler

@yo' bingo!

yo'

@PaulGessler :)

10:50 PM

@PaulGessler 0=escape 1=begin group 2=end group 3=math shift 4=tab 5=end-of-line 6=parameter 7=superscript 8=subscript 9=ignore 10=space 11=letter 12=otherchar 13=active 14=comment 15=invalid. All from memory. What did I win?

yo'

@egreg Surely something from the last group :P

egreg

@yo' ^^?

@yo' Let's see if you get it. ;-)

yo'

@egreg \catcode`\e=15\catcode`\g=15\catcode`\r=15

@egreg well, that's the only one invalid in plain, no?

egreg

@yo' :)

yo'

btw, your nickname is a nice $5/3$-power, as I just realized

Paul Gessler

10:54 PM

@egreg show-off :p :-)

egreg

@yo' And {\manual\char`\^^?} prints the dangerous bend symbol (if you do \input manmac)

yo'

@egreg one of Don's jokes? :)

egreg

@yo' Maybe. \char0 is the negative of the dangerous bend

yo'

11:17 PM

How would you typeset weight percents? The authors use 50\,w.\,\% -- is that ok? I would say so, but I'm not sure...

Paul Gessler

11:27 PM

@yo' I've always seen it as wt\% but it may vary by the field, not sure.

yo'

@PaulGessler well, it would certainly look better. This is some chemistry of nanostructures

Paul Gessler

@yo' here's an example of that notation in that field: books.google.com/…

That's way outside my area of experience though. :-)

yo'

@PaulGessler I think I'll change it.

Gregory

I'm using TeXLive on my Mac at home and MiKTeX on the PC at work, syncing files via DropBox. MiKTeX is telling me that it can't write to the default target filename (which already exists), but when I have it write to a different file name, there's no problem. I haven't had anything else that looks like a permissions issue, so does anyone here have a clue what might be going on?

Headed home. Will check back later.
