@PauloCereda I can't now because it's frozen. Do you want to proceed? Are you sure? Are you a little too picky with typography? You know what I'll close myself with an unrecognized error. Kern with your system admin. 0x004560234

Great article on arara by the way. All of them are quite interesting!
@percusse I've just moved to a new building and had to take all the jokes off my office door. One of them was (now very dated): Microsoft announced today that the official release date for the new operating system "Windows 2000" will be delayed until the second quarter of 1901.
Been stuck at unlucky 13 for ever... And its only a matter of time before @DavidCarlisle learns tikz and then I'll be back at 13. I have been trying to tell him that tikz is just a fad. :-)
@tohecz I thought (having never used biblatex) that the official line was that makebst was needed because the bibtex stack language is somewhat arcane but biblatex customisation was so natural and lovely that such a thing shouldn't be needed?
@PatrickGundlach You have a bizarre alphabetic ordering: you corrected mathdesign to be under "m" and not under "f" and I agree, but I don't understand why times is before the tg... packages. :)
@DavidCarlisle I might be the "official line", but the truth is, learning makebst took 10 minutes, learning biblatex has already taken 3 hours and counting...
@DavidCarlisle The 'official' line is more that writing BibTeX styles is a separate skill from (La)TeX programming, while biblatex styles are programmed using (La)TeX techniques, and moreover can be done within a document
@egreg Missed that one. brew install fontforge. Hmm, says something about linkapps ... must investiage.
Or even investigate
@PauloCereda I hope you're going to spell-check this interview before posting it. Since getting a Mac, my spelling has gone horrendously wrong. It keeps trying to put i in front of every word.
Is it possible to render a PDF in sepia tones, both the font color and overall document background? Preferably using pdflatex.
The final effect could be something like this screenshot of Pocket in sepia mode.
A friend of mine manufactured horse bridles. He buried every single piece for at least a month before using it. He said he didn't like the look of new things. :)
@PauloCereda That's similar to a strategy I've heard about where someone doesn't like spending money on new things. The others in the family buy stuff then hide them in the cupboard for a bit. Then when the stuff gets used it's "This? Yes, we've had it for ages."
I'm in the process of switching from BibTeX to BibLaTeX/biber. I've searched around but can't seem to find/figure out how to style the citations a particular way and I'd appreciate some help.
I'm using the tufte-latex package so citations appear in the margins. I'm looking to have the first occu...
@MarcoDaniel I have exchanged email with the last author from l2kurz - we can change the license to opencontent license. It is much simpler (and we can get rid of the gfdl pages)
@JosephWright Let me check the exam again ... Nope, it's Norwegian.
@egreg Yes, I'm none too keen on that either. One that makes me sigh quite often is when they multiply out something like (x-1)(x^2 + 4x + 4) and then try to find the roots of the resulting cubic.
@AndrewStacey In a test for freshmen at an Italian university one of the questions was: "Determine the solutions of the equation (x–1)(x–2)(x–3)(x–4)(x–5)=0". Not a small number of the students did all the multiplications and then determined the roots trying the divisors of the constant term.
@AndrewStacey This looks like an excuse for avoiding the interview.
@tohecz One of the students in my last course on Didactics of Math presented a test given to a young boy (high school freshman): "determine the equation having the solutions 1/2 and -1/3". :( The equation! Sob.
So it's not always the students' fault.

@tohecz The matrix delimiters are only a graphic expedient, after all. They have no inherent meaning; this is useful when using partitioned matrices: one can put whatever delimiter one wants also inside the matrix just to underline its structure.
@egreg I think the sometimes debatable skills of highschool math teachers are one of the major reasons for some students' belief that math is full of unfathomable mysteries they don't have a chance of ever understanding.
@StephanLehmke Your words are, more or less, the same as mine when I introduce the course. :)
I recommend to name the people that discovered math facts, putting them in a historical context, so the students can understand that math is something made by men and women, and not a mysterious law written on some inaccessible stones.
@egreg Well then you have the explanation for the multiplication thingy: It seems the solution is obvious but there might be something mysterious going on ;-)
@egreg I find this especially important wrt. proofs. To know that a seemingly simple proof of some basic theorem has gone through hundreds of years of refinement is an important part of coping with ones own percieved inability to prove even the simplest things ;-)
@StephanLehmke Examples like this are difficult to find for first or second year high school students, but of course they are very important. Another example I give is that of Apollonius' "Conic sections", which had their first application to "the real world", namely physics, 1700 years or so after having been written (first ballistics in the 16th century, then Kepler in the 17th).
Another one is "number theory", which was just a source of amusement for mathematicians. Now RSA is based on the Euler-Fermat theorem. :)
@PauloCereda Unfortunately Portuguese only. :) A very good book is "What is mathematics?", by R. Courant and H. Robbins: it opens the student's minds. It's not easy, of course, but bright students can find much in it.
@egreg Indeed. :) I tried to find it in another language, but the publisher (Editora Livraria da Física) seems not to have translated books to English. :( A professor of mine once recommended Courant/Robbins book, but I didn't have the opportunity to buy it yet (it seems the book is available at bookstores around here, no need to import it).
@PatrickGundlach It's easier than Greek, we don't have complicated letters. :P
@egreg: the book I mentioned is my shelf next to a book by two Italians: Umberto Eco and Carlo Maria Martini. You probably know the book. :)
@PauloCereda I found it in my school's library when I was in my third year (we have five year high school): it gave me the last push to choosing math as my future.
@PauloCereda The comment thread is quite odd now, since @AndrewStacey has deleted his comments on "I" vs. "me". Have you seen the light now, Andrew? :)
@egreg Yes, but Andrew didn't seem to think so. There's an odd prescriptivist idea that these statements are derived from ellipsis of the verb, and so you should get the nominative case there. Similar craziness in things like "He is taller than I" (which linguistically should be (and is for regular speakers) "He is taller than me").
As you note, the simple fact is that ellipsis in English always requires an auxiliary verb, so you can't just strand the subject like that.
@AlanMunn We usually get "he is taller than me" right, because in Italian we use an oblique case for the pronoun: "è più alto di me". Personal pronouns are the only words in Italian where remnants of declination survive.
Also in Italian we have crazy grammarian: in "la mia casa è più grande della tua" most grammarians say that "tua" is a pronoun. Very strangely, these "possessive pronouns" are exactly the same as "possessive adjectives" and can be used only in coordination.
@PauloCereda In Latin it was "Caius altior est quam ego" or "Caius altior me est". We followed different patterns. :)
@PauloCereda Also, you have the 'que' which makes the structure look much more like a clause. In the Italian example, you just have the 'di', which is a preposition (although it can introduce infinitives, I think.)
@egreg This is a complicated fact. Although they inflect like adjectives, somehow they also have to have the function of pronouns.
@AlanMunn They disagree that there actually are "possessive pronouns" as distinguished from "possessive adjectives". Of course, grammatical classifications are always disputable.
@egreg Right, I understand the disagreement on the surface, but proponents of the "they're only adjectives" theory still need to account for the fact that semantically they function like other pronouns.
@AlanMunn They require the article. No (other) Italian pronoun does. They don't require it only when used as copula (and so are adjectives): "Il libro è mio".
@egreg Right, I agree with the syntactic analysis, since those arguments are very strong. The problem that remains is that in terms of anaphora, they behave like other pronouns, despite the fact that they are adjectives. This is a non-trivial problem.
@egreg No, it's just the genitive case of the regular pronoun. So if you think of a pronoun as abstractly [Pron: xPerson, yNumber, zGender, rCase] you can then map those into their respective forms in the the paradigm, so [Pron: 3P, Sg, M, Gen] -> his.
@AlanMunn Pretty much everything. :) I don't know much things about grammar, morphology and other linguistic subjects. Besides the intellectual barrier, there's also my language limitation which doesn't allow me to follow most of the explanations. :)
@egreg But that's the history of a field, not the history of a natural phenomenon. What I mean is that a child learning a language must develop an analysis of the phenonemon as it is now, and that analysis cannot possibly require reference to the history. Knowing the history may help explain some things, but the history itself can't be part of the synchronic analysis.
@egreg Sure, we agree on that. Although at the right level of abstraction, all languages must be the same.
@DavidCarlisle Ah, but some of use make it up for a living. :)
The common spelling of math_mode seems to be with a space in between the words: There are 109 questions with math mode in their title, but only 17 with mathmode. Herbert Voß's paper Math mode spells it with two words, too. Hence, I suggest mathmode be normalized to math-mode, just like we have ta...
@JosephWright Do you want one more vote? I don't have much of an opinion. I agree a bit with Paulo. But the logic is clear. I'm not sure the badge issue is a big deal, but I don't pay much attention to badges any more.
@PatrickGundlach One suggest: I think l2kurz is an online documentation. So we can use \href{}{} instead of \url. I will add something to the biblatex part and I will edit the math part
@PatrickGundlach Not really. unknown entries use @misc

@AlanMunn Well, at least we aim at writing better code in the future. :) If you get the first version of my songbook, I'm sure you'd be scared of how many good practices I infringed. :D

64 min: Replays show that ball was over the line when Terry hooked it clear. The goal-line official couldn't advise the referee to give it, however, because the goal-post was blocking his view.

If a cake is cut into $5$ equal pieces, each piece would be $80$ grams
heavier than when the cake is cut into $7$ equal pieces. How heavy is
the cake?
How would I solve this problem? Do I have to try to find an algebraic expression for this? $5x = 7y + 400$?
I'm trying to come up with a renewenvironment for question tex.stackexchange.com/q/60434/3235 and I 've tried the following can someone tell me where I did wrong or even answer the question directly ?
@cmhughes I think the problem is that the commands are still read by the parser which we should have hid it from it by DoNothin. I tried some ideas from the question 308 but no avail.
@egreg (@percusse) thanks for the answer! +1 your remark at the end of the answer summarizes my only follow-up
@leo how about break it into 2 branches \draw[domain=-5:-0.01,samples=100] plot(\x, {sin(\x r)/\x}); and \draw[domain=0.01:5,samples=100] plot(\x, {sin(\x r)/\x});
@egreg do you mean in line images? if so, that's not a concern
@egreg @percusse one of the keys to the axis environment is width=.... Could one read the key before renewing the environment? (another key is height, which defaults to the same as width)
@egreg pretty much all of them specify the width in a way similar to this (e.g width=.33\textwidth). the width is not the only key though- there's usually an xmin, xmax, etc
