TeXtalk - Interviews

Everybody is welcome to ask questions and add remarks. :) We don't follow an specific order, so feel free to ask whatever you want. We will organize the flow later on by our awesome reviewers. :)

@UlrikeFischer: Could you tell us a bit about you? :)

Ulrike Fischer

1:11 PM

(I'm copying this mostly from an interview I gave Dave Walden some years ago (http://tug.org/interviews/fischer.html): I was born 1961 in Stuttgart in Germany as the oldest of three children. As child I moved with my parents first to Geneva in Switzerland (my father worked for IBM at this time) and later to Bonn in Germany. There I finished school and then studied mathematics at the University of Bonn until I got my “Diplom” (don't ask me how you say this in English).

With my husband I then moved to Siegburg (a town about 20 km away from Bonn) where we lived about 20 years. Since nearly th…

egreg

@UlrikeFischer When and how did you meet TeX?

Ulrike Fischer

I didn't use TeX at the university or for my thesis. I saw sometime in the second half of the 1980s in a magazine for the Atari a description of an Atari implementation of TeX together with a small introduction to LaTeX and ordered the discs.

Paulo Cereda

@UlrikeFischer: What was your first TeX document? :)

Ulrike Fischer

@PauloCereda I have no idea. Probably a hello-World-document - I always start with simple examples when I try to learn something new.

egreg

@UlrikeFischer And the first "serious" document? Did you use Plain, AMS-TeX or LaTeX?

Ulrike Fischer

1:27 PM

I have always used LaTeX for every "real" document, plain only for tests. As I had already finished my thesis I wrote mostly short private documents: letters, reports about the results of chess tournaments that I had managed and things like that. I also wrote all documents in my job with latex.

lockstep

@UlrikeFischer From the various support functions you offer at Troubleshooting TeX, what are the ones most in demand?

Ulrike Fischer

@lockstep I can't really tell yet. I'm only doing it for some month ;-). Currently it splits between people wanting tikz-graphics, biblatex styles and "general help" to correct various problems in partly finished large documents.

ricmarques

@UlrikeFischer: Hi! :) What is your (usual) working environment for LaTeX? I mean what Operating System, Editor, (La)TeX distribution and other tools do you normally use for your LaTeX documents?

Ulrike Fischer

I'm using windows (XP and 7 currently), miktex 2.9, winedt 7 and as pdf-reader mostly adobe reader. But I also have a texlive 2012 installation which I use for tests.

Paulo Cereda

@UlrikeFischer: Could you tell us a bit about your first package? :)

Jörg

1:42 PM

@UlrikeFischer Based on some of the answers you gave here on tex.sx I guess that fonts, font selection etc. are an interest of yours. Could you tell us a bit about that and also about your other interests regarding TeX?

lockstep

@UlrikeFischer You're quite active at tex.sx (at the moment 674 answers, 86 "Nice Answer" badges), yet you hardly ever vote (4 votes cast). Why is that?

egreg

@UlrikeFischer For anybody interested in fonts, Xe(La)TeX and Lua(La)TeX are very welcome tools. Do you use them?

tohecz

@UlrikeFischer and one more that may be related to fonts: Would you like to participate in the new Typography.SE site?

Ulrike Fischer

@Jörg I got interested in fonts because of chess: I wanted to use some other fonts than the standard skak fonts. So I tried to find out how it works. And this meant that I often could answer questions about fonts which increased my knowledge. Regarding my other interests: quite varied. I like to investigate problems and it doesn't matter much what is the actual content.

Harish Kumar

@UlrikeFischer: You are very active here as well as in winedt mailing list too. I was wondering how would you manage to get that much time (keeping in mind the family business and the work!). May we know the secret behind it please?

Ulrike Fischer

2:01 PM

@lockstep: I'm a unvoting person. I don't click on "I like it" buttons, don't twitter, don't sent comments everywhere. Actually I'm a bit reserved regarding the voting system. The badges remind me my time as "boy scout" as a child: Everytime we completed a task we got a badge to sew on our shirt. But I don't think that adults should be rewarded in this ways.

@lockstep: (continued) And while I do find it quite useful if people can discern between "regulars" and "newbies" and see some statistic I do find the voting system a bit too "playful" and some discussions about it a bit absurd. Imho it would be quite enough to simply count the number of (accepted) answers.

tohecz

@UlrikeFischer that would IMHO be even more "playful" but that's another story and probably not a part of an interview ;)

lockstep

@UlrikeFischer I just checked egreg's no. of accepted answers (2,004, out of 3,407 answers), so I guess he'd still be our top user. ;-)

Ulrike Fischer

@egreg: Yes I'm using them (and I have written an introduction to xelatex some years ago). But as most of my texts are in german or english and don't use other scripts there is no pressing to drop pdflatex.

@tohecz: Probably not. I'm already involved in too much, also my interest is more on the side "how to use fonts in (La)TeX".

Paulo Cereda

@UlrikeFischer: Could you tell us a bit about your first package? :)

Ulrike Fischer

2:17 PM

@HarishKumar: I'm not very active on the winedt list. And regarding my time: For most of my answers I don't need much time. If you look at my answers, you probably will see that I ask quite often for minimal examples and seldom send long answers with a lot of code. And for the ones which needed some thinking I use the time when I do my shopping.

tohecz

@UlrikeFischer You're able to do think of LaTeX when you do shopping? And which version of the package brain do you use? :D

Ulrike Fischer

@PauloCereda: My first package was chessfss which enables users (and packages like skak and xskak) to switch between chess fonts instead of using a hard coded font.

@tohecz: We are living in the middle of the town and I can do almost all my shopping on foot (or at foot or by foot or whatever). A lot of people think best when walking.

tohecz

@UlrikeFischer Yeah, but this doesn't work when dealing with computers, does it?

Paulo Cereda

@UlrikeFischer I do the same. :)

percusse

@UlrikeFischer Did you ever think of designing a font (apologies if I've missed it/them)? And given your knowledge about fonts, what are the distinct challenges between the regular fonts which are relatively easy to design (beauty/comprehensiveness is another story) and a font which specifically designed to be used via (La)TeX?

Paulo Cereda

2:24 PM

@UlrikeFischer: what's your favourite chess grandmaster? :)

Ulrike Fischer

@tohecz: Certainly it does. There are certainly a lot of problems - eg. when you have to create a picture - where you have to sit before the computer and test code. But in many cases you have to understand the structure of a problem and such cases it helps a lot if are away and have to concentrate on the main points. It helps you to develop simple and clear solutions.

egreg

@UlrikeFischer Most of your solutions are very compact and "simple". Have you a secret to share?

Ulrike Fischer

@percusse: No. I'm not a designer. I can handle the technical side of fonts in LaTeX, but I'm not good in beautiful curves and colors and so on. There is nothing special in fonts meant for LaTeX apart perhaps the character set: some accented chars from T1-encoding are often missing.

@PauloCereda: I don't have a favourite chess grandmaster. I also don't have (and never had) a favourite singer or actor or boy group. But my favourite piece of music is Bach's "Air".

percusse

2:46 PM

@UlrikeFischer With Bobby McFerrin and Yo yo Ma or without ? :P

egreg

@UlrikeFischer What do you like to do in your spare time (assuming you have)?

Alan Munn

@UlrikeFischer Hi Ulirike. Thanks for all your work over the years on the XeTeX mailing list and c.t.t. I've learned a lot from reading your posts. I'm so surprised you don't have a favourite boy group. :)

Andrew Stacey

I'm quite curious as to your motivation for participating here. You seem to be something of an answer machine (if that doesn't sound too offensive!) in that your modus operandi seems to be simply to answer things. So what keeps you coming back here to answer more questions?

Ulrike Fischer

@egreg: My solutions are mostly simple because I' m not very good (and to lazy) in handling complicated solutions. Also I'm a mathematician and my interest has always been in structure and logic and so I always try to put some clear plan behind my solutions. In my spare time I like to answer questions about TeX;-)

@percusse I don't have an special interpretation as a favourite.

egreg

@UlrikeFischer What do you think of Altbier, which I believe is typical of Mönchengladbach and surroundings?

Paulo Cereda

3:07 PM

@UlrikeFischer: How did you become aware of the TeX.sx community? :)

Ulrike Fischer

@AndrewStacey: I like to investigate and solve problems. I like to learn and to understand things. I also like to teach people. When I answer (La)TeX questions I often get all three together: An interesting puzzle, something new to learn and the opportunity to explain this to someone else. So it is better than crosswords.

Faheem Mitha

@UlrikeFischer Does living in Germany have any bearing on your interest in TeX? 0r do you think you would have been as interested living somewhere else? Please ignore if this is too vague.

Ulrike Fischer

@egreg: I don't drink beer, I prefer wine. Altbier is typical but as far as I know iother beer type (Kölsch and Pils) are slowly taking over.

Faheem Mitha

The reason I ask it that Germany is a very tech-friendly place, at least my perception of it is so.

And they have a big TeX community - user group and so forth.

tohecz

@UlrikeFischer speaking of drinks: coffee or tea? :)

Ulrike Fischer

3:18 PM

@PauloCereda I think someone mentioned tex.sx in comp.text.tex.

Paulo Cereda

@UlrikeFischer: Do you have a favorite answer of yours? :)

Faheem Mitha

@UlrikeFischer If I might, a (boring) computer question. What version control do you use?

Ulrike Fischer

@tohecz: Tea

texenthusiast

@UlrikeFischer Which one is your favourite TeX or LaTeX books ?

lockstep

@UlrikeFischer Besides the voting system, there's another feature that distinguishes tex.sx from traditional forums: the ability (for high-rep users) to edit other user's posts. What's your stance on that?

Ulrike Fischer

3:33 PM

@PauloCereda I have to many answers to be able to name a favourite. One I like is this one: tex.stackexchange.com/questions/68098/…. I like it because it changed the focus of Phineas. If I remember correctly I thought about it while walking to get bread and I think I got the structure right.

@texenthusiast: The LaTeX Companion.

egreg

@UlrikeFischer Wow! That's an answer of the kind I was thinking before! (An August answer I didn't see, so I took the necessary step just now.)

Ulrike Fischer

@FaheemMitha: Mercurial but only for my packages (which wait that I find time for some updates). The rest of my document are not long (and important) enough for version control.

texenthusiast

@UlrikeFischer are you involved in teaching at Universities/forums or introducing LaTeX and interacting with TeX community activities on any level ?

Paulo Cereda

3:48 PM

@UlrikeFischer: Can you name something you really like in TeX/LaTeX? And is there something you dislike?

Ulrike Fischer

@lockstep: I don't mind if some corrects my typos or my english or errors in my code. (Until now I reverted only one edit as it changed the meaning of my text). I do find it quite convenient that some "Heinzelmännchen" make the postings of others more readable or more beautiful.

@texenthusiast: I'm not teaching LaTeX (apart from all the teaching I do in the usenet/internet/mailing lists). But in next summer I will perhaps give a training course at the "Volkshochschule" - if there are enough interessents.

@PauloCereda: Imho it is difficult to answer such a question without something to compare to. I like latex compared to word for other reasons than latex compared to context or plaintex.

Paulo Cereda

4:04 PM

@UlrikeFischer: Ready for LaTeX3? :)

Ulrike Fischer

@PauloCereda: Yes ;-) I actually have a mostly finished update of chessfss written with expl3. There are quite a lot goodies in LaTeX3 (like e.g. the list handling) and the documentation is really good. One only has to get used to all the : and _ and the naming convention.

Paulo Cereda

@UlrikeFischer Indeed. :)

@UlrikeFischer: Any plans for a new package? :)

Ulrike Fischer

4:21 PM

@PauloCereda I plan a replacement for xskak. The new package will not use the skak package to parse chess notation but its own parsing code. The main problem is the printing of the chess notation: It is difficult to design a powerful, flexible yet usable interface. In xskak there is a sort of style managment but imho it is too complicated. Even me who has written the code can't use it properly ;-).

Paulo Cereda

@UlrikeFischer :)

egreg

@UlrikeFischer Nice to know that you joined the group of LaTeX3 package writers!

Paulo Cereda

@UlrikeFischer: Bruno Le Floch recently wrote reverxii.tex, an implementation of the Reversi game in plain TeX (heavily inspired by @DavidCarlisle's xii.tex). Perhaps we can teach TeX how to play chess too? :)

Ulrike Fischer

4:37 PM

@PauloCereda Well a friend of mine wrote once a simple chess game: The computer simply made a random legal move. It shouldn't be too difficult to implement this in TeX;-). But beside this: Already the parsing of chess games is quite slow, a good engine would probably need month for a move.

Paulo Cereda

@UlrikeFischer Indeed. :)

@UlrikeFischer: What do you recommend for a newbie eager to learn TeX, LaTeX and friends? :)

Ulrike Fischer

@PauloCereda Don't use a large template. Start with small documents. Run (in a test folder) as many "minimal examples" as you can and play around with them. If you use a new package read the first pages (after the installation instructions) of its documentation and try out some of the commands so that you have at least a vage clue what the package is doing.

3

@PauloCereda (continued) If you have a problem: Don't google around for hours but set you a time after which you should try to get sensible external help: This can - depending on the type of problem - be a forum, a friend, a local tex group or professional help.

Paulo Cereda

4:53 PM

(Friends, I'm out of questions. Any more questions?)

lockstep

@PauloCereda I think Ulrike's last answer makes for perfect closing words.

Paulo Cereda

@lockstep Indeed. We will save them for the end of the interview. :)

egreg

@lockstep A big thank to Ulrike!

texenthusiast

@UlrikeFischer very patient like TeX

Paulo Cereda

@UlrikeFischer: Thanks a million for this awesome interview! :)
