@PauloCereda With anchovies?

@PauloCereda In Italian, acciughe. In the dialect of Genoa they are anciue that should be similar to Portuguese.

1:02 AM

Hello, everybody :)

@PauloCereda It's really cool. I was 111% sure it can't arrive, it's lost.

@PauloCereda Hi! ;)

David says presumably and egreg says not really...

Actually, not sure I could get it to work even with a counter...

i am scared of TeX capacity exceeded errors

1:28 AM

@twirlobite we all are, so we try the best not to get them :)

heh

@egreg ooh so that's the flavour I couldn't identify! I was anchovies!

@yo' A late Christmas miracle, it appears. Sorry if it's silly, I thought I could make you smile with a song. :)

@PauloCereda That's what “pizza alla romana” generally means.

@egreg Yay, now I know! :) It was delicious!

Morning all

10:46 AM

@JosephWright Top of the morning, sir!

@PauloCereda So you recovered from the conference?

@egreg Almost. :) I'm feeling a lot better. I was missing my bed. :)

11:01 AM

@Johannes_B I wanted to precede somebody who may be working on a Plain TeX version, reinventing the wheel each time.

@egreg \@for against xparse again, let's see who gets the tick:-)

@cfr for any counter you just need to do \edef\@currentlabel{\value{counter}} so that can be yes or no to "is there a latex3 way" depending how pure you are (where \value{..} might need to be \the\... depending

What about \myfunc{ a , b,c ,x,y , z }? :P

@egreg the brilliant latex2e addition of \zap@space was designed for exactly that use.

@DavidCarlisle OK, what about \myfunc{a a, b b} if you add \zap@space? :P

@egreg It works as specified.

11:43 AM

@egreg: we will have tortellini today! :)

@PauloCereda Good!

@PauloCereda now, what were we planning to have later today....

@DavidCarlisle Oh no, oh no, oh no!

@DavidCarlisle: could it be some chicken that took swimming lessons? :)

user image

^^ SuperBowl. :)

12:30 PM

Hey everyone! :)

@Iplodman Aloha!

How are you? :)

Fine, thanks. :) You?

Good ;P

Just writing a LaTeX doc for someone.

1:13 PM

@PauloCereda Guess what I had for lunch!

1:30 PM

@egreg Tortellini too? :)

2:17 PM

@PauloCereda well, I still don't understand why the Americans insist on calling a throwball football.

@DavidCarlisle DropBox updated

@yo' because the settlers played rugby rather than association football, probably:-)

@JosephWright thanks

@DavidCarlisle but they messed up the names, and now the try to force us to use soccer for football

@yo' Well soccer is just short for association football, so ...

@JosephWright so it's football. Full stop.

2:31 PM

@yo' Nah, cause there is union football (rugby union), league football (rugby league), etc.

@JosephWright where?

@yo' football as an organised game started at Rugby, with a squashed ball, association football with a round one is a later variant

@DavidCarlisle comon, football was played before English was known as a languuage

@yo' Yes but with rules somewhere between any of the regularised games of the modern day

@yo' Of course but it didn't have that name, and formal written rules.

2:34 PM

@DavidCarlisle ... and of all games you mention, the only one played by feet is ... ?

@yo' you are allowed to kick the ball in some circumstances in rugby football, as opposed to just running with it:-)

@yo' It matters little, as none of the mentioned games is cricket

2

@DavidCarlisle with the emphasis on in some circumstances. In football, there's one player that is allowed to use your hands in some circumstances. :)

@yo' and why don't they use a bat?

is cricket the second name of ridiculous? :D

@DavidCarlisle it's not a batball :D

@PauloCereda Yes!

1 hour later…

3:59 PM

@egreg Yay!

4:20 PM

@PauloCereda The 0:0 at Udine is not so nice. ;-)

4:36 PM

@DavidCarlisle Thanks - the mixture of syntax I end up with just seems odd, but it works which is the main thing ;).

@JosephWright While you're at fixing LaTeX, you should change nfssfont.tex; line 304 should be \def\:{\setbox0=\hbox{\noboundary\char\n\noboundary}% instead of \def\:{\setbox0=\hbox{\char\n}% so the shown character is not influenced by the boundary character (if the font sets it).

@DavidCarlisle ^^^ ?

@egreg I mainly do L3 stuff ;-)

@egreg Co-opted onto L2e for Unicode experience :-)

@JosephWright @DavidCarlisle I was puzzled for a while when examining the output of pdflatex nfssfont in connection with tex.stackexchange.com/questions/225902/…

@egreg Mumble No code comments

@JosephWright It's basically copied from testfont.tex that's described in the METAFONTbook

4:50 PM

@egreg So it is DEK's fault :-)

@JosephWright YES!

@egreg :-)

@egreg Need to see what @DavidCarlisle (and probably Frank) think

@JosephWright testfont.tex did not change in the passage from TeX2 to TeX3 (when the boundary character feature was added).

@egreg I guess not

@egreg Oh. :)

:)

@JosephWright David will probably link this: en.wikipedia.org/wiki/Principle_of_least_effort

4:54 PM

@egreg Report a LaTeX bug?

@JosephWright OK

5:10 PM

@JosephWright Submitted

@JosephWright @egreg it's all Greek to me

@DavidCarlisle Don't you know Greek?

@egreg seems safe enough @JosephWright we slip in a fix in time for Tl2015?

@egreg My Greek is as good as my Italian and Portuguese

@DavidCarlisle If the boundary char is not set, \noboundary should do nothing.

@egreg it's even defined to be \relax by latex.ltx on tex2 so safe there as well

5:29 PM

@DavidCarlisle I'll send it to Karl for the next bug fix to TeX and friends.

5:43 PM

@DavidCarlisle Guess what? Line 175 of testfont.tex is \def\:{\setbox0=\hbox{\noboundary\char\n\noboundary}%

@egreg Indeed: @DavidCarlisle a straight-forward fix?

6:00 PM

@JosephWright probably if I wasn't committing fixes for mathjax's mathml support, (another interesting mix of svn and github:(

@DavidCarlisle OK, I'll do it

@DavidCarlisle Don't expect me to tackle Gnats though

@DavidCarlisle Did you send the mail we discussed?

@JosephWright No, was waiting but I guess I should. OK if you fix the code I'll fix gnats and try and think of a polite reply to put in the database to @egreg

@DavidCarlisle Bug is in the wrong place, no? It's kernel not tools!

@DavidCarlisle Running test suite now :-)

@JosephWright Oh good, so I can send an impolite reply to @egreg:-) (I can move it once I log in to gnats)

@egreg, @DavidCarlisle Fixed checked in

6:18 PM

@JosephWright and (other) mail sent

@JosephWright Ok will send gnats reply

6:43 PM

@David: mind if I ask you a XML question? :)

6:58 PM

oooo pgfplots update today, just noticed in my RSS :-) :

mail-archive.com/ctan-ann@dante.de/msg06775.html

@PauloCereda ask anyway, then I'll tell you if I mind

@DavidCarlisle :) IIRC XML preserves element order, whereas attributes can be permutated as one desires.

Is this correct?

@PauloCereda yes although actually the xml spec doesn't specify element order (as it was written by document geeks who thought it obvious that you shouldn't shuffle paragraphs in a document) which came as a bit of a shock to some of the early implements of mapping to relational databases as they just assumed order didn't matter:-)

@DavidCarlisle Ah thank you. :) I was scared for a minute. :)

@PauloCereda but later specs that actually specify parse results like DOM and infoset and XDM (Xquery data model) all do specify element order is preserved.

7:06 PM

@DavidCarlisle Cool. :)

@PauloCereda really the xml spec just specifies the syntax with almost no definition of an underlying model for any parse result so it's quite hard for it to specify that element order is preserved basically it just defines a boolean result for is-well-formed. An xml parser isn't obliged to return anything other than that

@DavidCarlisle Hm I was tempted at first to include an id attribute to each element so I could post-process that value and ensure ordering to my collection. :)

Go Aquactic Hawks!

^^ Ready for the SuperBowl!

@PaulGessler: ^^ <3

It's the closest we have to a duck-related team. :)

@PauloCereda as I say, a parser that shuffled every paragraph of every document wouldn't be universally popular.

@DavidCarlisle Indeed.

@PauloCereda hmm nice smells coming from the Kitchen...

7:12 PM

@DavidCarlisle oy

@PauloCereda not so keen on the Seahawks at the moment, since I am a Packer fan from Packer country :-) (Packers lost to the Seahawks in overtime in the playoff game deciding the Super Bowl team...)

@DavidCarlisle Speaking of bug reports: why isn't latex-project.org/cgi-bin/ltxbugs2html?pr=latex/4406 already closed?

But then again, not a huge Patriots fan either. Basically I will watch the game because I'll be considered a social hermit if I don't... :-)

So the duck is no more. You mean. :)

@egreg Either it's waiting for Rainer's cron job to re-sync the public view, or I didn't close it correctly, but I thought I did (did you get the change status mail from gnats?)

7:14 PM

@PaulGessler Packers = Greenbay? I'm terrible with names. I just watched SuperBowl quite recently (the first one was when the Saints won).

@PaulGessler You naughty boy, you want to watch Katy Perry too. :P

@PaulGessler Just refer people to the starred comment on the right

@PauloCereda yes, Green Bay is about 2 hr drive from me (1 hr from my hometown)

@PaulGessler Yay!

@DavidCarlisle I starred that, but I still know nothing about cricket :-)

@PaulGessler No one really does, except for Nicola. She wrote a scoreboard in LaTeX. :)

7:16 PM

@PauloCereda you must, since Psmith learned from you!

@PaulGessler ah:-) You probably know more than I do about American football (although I went to a college game once, was a bit surprised to find 80000 people there, I thought it would be on a field at the back of the university somewhere:-0

@PaulGessler Nah, Psmith needs David. :)

@PauloCereda don't tell my wife that!

@PaulGessler Roger, sir!

:-)

7:18 PM

@DavidCarlisle ^^

hello everyone :)

@PaulGessler: youtube.com/watch?v=DygBFPiUfEM

@cgnieder Hi Clemens!

@DavidCarlisle some people go a bit crazy in my opinion. (Though I suppose the same can be said for all sports.) I'm not as excited about it as I used to be. My family is very lucky to have season tickets (50-something year waitlist), but I haven't gone to a game for several years.

@cgnieder hello!

@PauloCereda working on your song collection?

whoa, Wikipedia reports that the waiting list is 955 years?! That can't be right!

7:21 PM

@cgnieder o.O HOW DO YOU KNOW ABOUT THAT?!

Germans are dangerous. <3

@PauloCereda :) just a guess...

@PaulGessler LOL

NFL season ticket waiting lists

The National Football League has enjoyed success in selling out many of their venues from season ticket sales alone. Out of 32 teams in the league, 24 claim to have waiting lists from under 1,000 people to over 150,000. For some fans, this means a wait not just of years, but decades. This is due mostly to the NFL's short window of play; there are only eight regular-season home games, forcing the most devoted fans into a desperate and sometimes costly search for a limited number of events. Since 1973, the waiting lists have also had the by-product of preventing any home games of certain teams from...

@cgnieder It was a guess... /logouts ssh connection in Paulo's computer

@PauloCereda lol

7:24 PM

@cgnieder I thought of writing my own format, but I'll probably stick with XML.

@PauloCereda far better than that yaml nonsense

@PauloCereda If I recall correctly you once told me your collection includes more than 1000 songs?

BTW: I had an awesome first gig with my new band on Friday night. I'm still a bit euphoric...

@DavidCarlisle YAML would be a very very bad choice. :)

@cgnieder Wow, congrats! Yay!

@cgnieder Here:

[paulo@cambridge source] $ grep "beginsong" religiosos.tex | wc -l

@PauloCereda impressive

@PauloCereda it's a live karaoke band (so we don't have a singer but still are seven people...) and the place was crowded as I've never seen it before. Everybody's been nice and supportive towards the singers. Great audience and a lot of fun :)

@cgnieder Awesome!

7:40 PM

@cgnieder sounds really great! Congrats on forming the new band!

@cgnieder: band name? :)

@PaulGessler thanks! It's been a lot of work the last months: we needed to rehearse at least 40 songs to choose from (and all the other stuff: promotion, ...) but it was definitely worth it :)

@PauloCereda a quite German name: HitSchmitz :)

@cgnieder oooh! :)

any texworks users? is there a menu option to see the log?

Q: I don´t get any compliling errors even though there should be and I don´t think I can find a log file

I recently downloaded miktex and wrote my first file in TeXworks. I managed to turn it into a pdf, until I realized that part of the text was hanging out of a line (basically the classic overfull hbox error.) But shouldn´t there have been an error notice telling me this? I read in a manual that ...

installing compiling

@DavidCarlisle Ctrl + \ toggles log pane at the bottom of the screen

There's a menu option too, let me find it

@DavidCarlisle Window -> Show Console Output

7:59 PM

Does anybody have an Xbox One?

Why do you \input opmac when only using a small part of its capabilities? — Paul Gessler 1 min ago

xD

@PaulGessler do you want to answer:-)

@DavidCarlisle I'm not sure what to answer?

@PaulGessler you may be reminded of that comment next time you load half a million lines of tikz to draw a box around something....

@DavidCarlisle :-)

8:11 PM

@PaulGessler just what you said to me, I think, or anything more specific about how to locate the overfull box warning, if it has a step through warnings feature?

@DavidCarlisle ok, working on it now

@PaulGessler thanks

@DavidCarlisle @PaulGessler well, you may reminded of that comment when you load LaTeX instead of plainTeX next time...

@yo' but @PaulGessler always uses picture mode so at least that part of latex doesn't go unused.

@yo' indeed, along with being corrected that LaTeX doesn't use boxes because it's built on top of TeX. In the same way that I don't drive my car because the sole of my shoe actually touches the gas/brake/clutch pedals, not me.

8:28 PM

@DavidCarlisle Yes

@egreg: one for you:

Q: Markdown editor, with MathJax, doesn't seem to support some LaTeX commands. TexMaths refuses to use the font. How to fix it?

I'm a newbie to LaTeX, TeX and other TeX-like, so I'm beginning to study Computer Science. I have some problems with Markdown editor and TexMaths (LibreOffice's plugin). I have already read the following questions at this TeX forum and outside: 1) Simplest way to typeset entire document in sa...

xetex pdftex svg mathjax markdown

@DavidCarlisle Brazilians. :)

He's just joined so closing seems unfriendly but I can't even find a question I could answer, so I'm tempted to vote off topic

@PauloCereda oh yes, SP, you could go round and sort out his problems

@DavidCarlisle Guaratinguetá is the city where our first saint was born. :)

9:13 PM

@PaulGessler I lost you. I just say that we all often bring in a heavy toolbox to tie a shoelace.

@yo' I know this, and I'm OK with that. But that particular answer put me off because it was "correcting" the OP's terminology, saying that LaTeX does not use boxes because it is not TeX, but built on TeX.

9:46 PM

Well, the Super Bowl party plans have fallen apart, so I'll be watching at home after all. We have large snow drifts in the parking lot at our building; there's a line of cars forming to become the next one to get stuck. :-)

@PaulGessler Really, parties?

@PaulGessler that \mathclap suggestion should be the answer I guess

@JosephWright well not really a "party" I guess, but here it's traditional for people to get together and watch the game, eat, drink beer, etc. I was going to go to a friend's place, but road conditions are probably the worst they've been all season today.

@PaulGessler Ah

@PaulGessler Your team in the final?

I was out earlier this morning and it was passable, but it's only gotten worse as the day's gone on.

@JosephWright No, sadly. :/ We (GB Packers) were close, but lost to Seattle in overtime two weeks ago in the game deciding who went to the SB.

9:52 PM

@PaulGessler Ah

@DavidCarlisle oh yes, I'll go back and write it. Forgot about that comment already. :-)

@cfr You shouldn't scare users with phrases such as ceteris paribus ;-)

@DavidCarlisle is there no good dupe for that one? I didn't look very hard.

A: How to extend the text under summation symbol without making extra space

You can use \mathclap{....} from mathtools: \documentclass{article} \usepackage{mathtools} % \begin{document} \[ a(i,k) \leftarrow \min\Big\{0, r(k,k) + \sum_{\mathclap{i^{'} | i^{'}\notin \{i,k\}}}\max\{0, r(i{'},k)\}\Big\} \] \end{document}

@PaulGessler different operator but could be a dup I suppose

10:15 PM

@DavidCarlisle the gold-badge hammer has spoken. :-)

I'm glad I don't have to worry about that responsibility yet. I'd rather make suggestions and let the community decide.

@PaulGessler Ah, welcome to my world!

I think this is the crowd who gets this

SuperBowl live commentary in this chatroom from a duck bee that has no bloody idea of what's happening on TV!

Some guy is a quarter something.

Quarterback, sorry.

Wow, I didn't know Bob Marley played American Football.

Patriots entering.

Some guy named Tom ~~Hanks~~ Brady is famous.

Why is he going to the bench?

wooooo Seattle!

There's an eagle running in the field.

ESPN is showing a flashback on how each team got in the SuperBowl. I have no idea of what's going on.

@PauloCereda Didn't you see @PaulGessler's explanation above. You are supposed to party and drink beer, then it becomes clear.

@DavidCarlisle ooh! :)

ooh cheerleaders, hold on!

@PauloCereda tasty meal we had this evening!

@DavidCarlisle oy

Quacky meal. :)

11:16 PM

@PauloCereda So I finally remade this game I wanted to for a long time, this time in python. However, I'm currently unable to produce a Windoze EXE file for my friends :-/

@yo' py2exe or something freeze?

Now people are singing America the beautiful.

The dude is playing an Yamaha piano.

Shots from the Grand Canyon.

@PauloCereda yep, but these work on all platforms, meaning they produce an exectutable of your platform

@PauloCereda isn't it hard to play football when there is a piano in the middle of the field?

2

The Seattle space needle appeared too!

@DavidCarlisle LOL I wub you. :)

@yo' Ah. :)

Oh no, that woman from Frozen will sing the national anthem.

For God's sake.

@yo' can't you just give them python?

11:19 PM

@DavidCarlisle A good plan. :)

I'm expecting let it go let it go any time now.

... and the home of the brave!

And there were airplanes in the sky!

@PauloCereda That is where they usually are.

Commentator: That Frozen girl is the Barbra Streisand of this generation. Oh my.

@DavidCarlisle well, too complicated somehow. I'd prefer to be able to ship a single file (it shouldn't be that much a problem for a 400-line program

@DavidCarlisle LOL

@yo' they should think themselves lucky only to have the python runtime, @Paulo would have shipped it with a linux virtual machine

11:23 PM

@DavidCarlisle Docker application. :)

@yo' ironpython.net ?

@DavidCarlisle well, currently the Windows system in my VB is unable to create the window properly

@PauloCereda do you know how many players from each team are on the field at one time?

@PaulGessler I... I don't know! Oh my! Oh my!

Hold on, I'll try to count!

11:38 PM

@PauloCereda 11 each team, obviously.

@PauloCereda If they were 13, it would be rugby league, 15 for rugby union. Just think to cricket and you're done.

@PauloCereda It's a trick question: there are two people in some of the suits

@egreg @PauloCereda egreg gets the tick

@DavidCarlisle LOL

But yes, it was a semi-trick question: en.wikipedia.org/wiki/12th_man_%28football%29#Seattle_Seahawks

@PauloCereda did you spot Katy Perry yet? Which position is she playing?

Time for dinner; be back soon to rejoin Paulo's live-blogging entertainment :-)

@PaulGessler :)

Something is happening in the field. One team is trying to go to the other side of the field while the other team is trying to go to do the same but the exact opposite.
