@PauloCereda I suspect: new firmware, new experience would be closer to the mark. Even the kernel developers gave up trying to get it to boot properly. It never did boot the stub kernel from the hard disk. (Fine from the install media.) And I had to let Ubuntu overwrite my EFI partition to figure out how to get it to boot from the hard disk even with grub. (The Ubuntu installer was buggy. I wiped my EFI partition without installing a usable OS. However, that's pretty much what I wanted.)

@PauloCereda I got that Cortina thing because I was too slow figuring out the magic key for setup. However, finding the power off button was fortunately straightforward.

@PauloCereda Can't get plasma working yet, though. And my think light is not doing anything :(.

Q: The Hole in One Pizza

In a recent issue of Crux, at the end of the editorial (which is public), it appears the following very nice problem by Peter Liljedahl. I couldn't resist sharing it with the MSE community. Enjoy!

@DavidCarlisle ^^^

David Carlisle

6:39 AM

@CarLaTeX No Italian will be able to answer that question as they'll spend all allotted time arguing about the cultural indignity of making a square pizza

CarLaTeX

@DavidCarlisle LOL We make square pizzas too :P

Harald Hanche-Olsen

7:17 AM

@DavidCarlisle You could pose the same problem with a hexagonal hole in an elliptic pizza.

egreg

@DavidCarlisle That vast part of Italy you recently visited is unfortunately not well endowed with pizzerie, so you couldn't appreciate the joys of pizza al taglio, where of course pizza is rectangular.

@DavidCarlisle And has no pineapple on top

I feel like my questions receives more activity if I don't include a MWE ... because at least there will be one person saying I should include a MWE, then there might be another one seeing that comment and up-voting it. It sort of kickstarts the interest and adds a social context to the question.

@VincentMiaEdieVerheyen People who consistently don't include MWEs are likely to get down-voted.

@Andrew Thanks. I try my best.

Lembik

@DavidCarlisle Thanks. I only have lemmas (no theorems etc) in the talk

David Carlisle

@HaraldHanche-Olsen Or a circular pineapple on a square ham pizza

@Lembik still I don't think your question is answerable:-)

@VincentMiaEdieVerheyen don't do that! Just forcing activity to get the point where you should have started and the question can be understood is a waste of everyones's time, not useful discussion.

Lembik

@DavidCarlisle ok let me be clearer... I have white text on a black background. Currently the word Lemma is in blue but the statement looks the same as the rest of the text on the page.. that is white text on a black background

but I am not at all clear what a sensible set of colors in for this situation

David Carlisle

@Lembik yes but it's like posting to a global forum and asking if you should have mushrooms or pineapple on your pizza. There is no basis that anyone could suggest any answer.

Lembik

@DavidCarlisle surely mushrooms

David Carlisle

8:10 AM

@Lembik not if you are @CarLaTeX!

Lembik

:)

to be fair to me.. the main site is full of aesthetic questions

David Carlisle

@Lembik I probably wouldn't have changed the colour at all so I can't say (unless that is already an answer: white)

Lembik

@DavidCarlisle ok thanks

CarLaTeX

@DavidCarlisle Any Italian can answer No pineapple on pizza!

egreg

8:26 AM

@Lembik Once I reviewed a paper that ended with a lemma. :-) Unused elsewhere, of course.

Harald Hanche-Olsen

@Lembik Try googling for color schemes (or colour schemes … not sure if google knows these are synonyms). Learn a bit about how colours work, or use one of the tools out there to create a reasonably consistent colour scheme that you like. Otherwise, you're likely to end up with a hodge-podge of colours with no reason or rhyme to it.

Lembik

@egreg :)

@HaraldHanche-Olsen Thanks

Anonymous

@DavidCarlisle I was actually not being serious, just making a joke. But I should have made that clearer by mentioning something about a duck or a pizza.

David Carlisle

@VincentMiaEdieVerheyen jokes. oh we don't allow jokes here, pizza arguments are life and death debates.

mickep

8:49 AM

@egreg Out of curiosity, how did you comment on that?

egreg

9:19 AM

@mickep Please, add a theorem or remove the last part.

mickep

@egreg Well, that sounds fair.

@barbarabeeton I have a feeling that, using the amsart document class, the vertical space between the "Key words and phrases" part and the page number is too small. Do you remember if there have been any discussion on that? This is of course just my meaning, others might think it looks fine. (I know that I could just remove the page number, or perhaps manually move it further down (or the other text up), but the default should be fine, I think).

@Andrew Wow, I am very interested to dig into your new answer, but somehow I can't compile it? I don't know which compiler to use as well. Most compilers I try with (for example LuaLaTeX seem to give me an error for line 17 ... Undefined control sequence)

Anonymous

@Andrew If I compile using LaTeX, then I get the following error: ibb.co/kjrJFb

daleif

@VincentMiaEdieVerheyen is your latex installation fully up to date? I've used TeXLive 2017, no issues

If I then enter a little bit, then I get the following output: ibb.co/cJUYgG

@daleif I installed everything from tug.org/mactex only a month or so ago ... so I guess I should be up to date?

@VincentMiaEdieVerheyen did you copy the entire example andrew posted?

@VincentMiaEdieVerheyen Remember MacTeX is a snapshot from may/june, there might have been many updates since then.

update the maxtex, try sudo tlmgr update --all --self

in a terminal. There are other ways, this is just often the fastest

proceeding, thanks

daleif

There can easily be several hundred updates

wow, and how many hundreds of viruses

daleif

11:02 AM

since you have not yet updated since mactex was made

virus?

:) I sometimes wonder what I am installing you know ... of course we don't really check it

Anonymous

@daleif 350 updates indeed

daleif

That is actually one of the reasons I always install as myself, not as root (on linux), a bit safer. Probably not possible the way mactex runs

@VincentMiaEdieVerheyen well a lost smaller than the 3400 that is a full manual installation.

if Andrew's answer will work for
\IterateOverPunctutation{ABCD, BCDE::: PFEKAA.. DA}\Any
instead of just for
\IterateOverPunctutation{A, B: C. D}\Any
I am very excited about it .. it will be useful often for many applications

@DavidCarlisle I recently came to know that the "pineapple pizza" has become some kind of popular discussion here in Italy (who tried it, who opposes it, etc...) it wasn't so a few months ago... do you have anything to do with that?

Anonymous

@DavidCarlisle I see. thanks. Gotta love regular expressions ... I wonder how I can return the characters which are used as separators ... I asked a small question about it here: tex.stackexchange.com/questions/394199/…

@DavidCarlisle To be fair, we don't know if they had the same with other people :)

@PauloCereda -- i'm glad you're recovering -- pneumonia is not fun. and certainly not the best way to start spring. i just sent you a news item about brazil challenging canada in curling. now you'll have to become familiar with that too, as an alternative to cricket.

David Carlisle

@barbarabeeton also it's bad to get infected duck into the food chain

@barbarabeeton No relation to Chicken Little, I presume …

@barbarabeeton More at this link

@HaraldHanche-Olsen -- not directly, but there's a correlation in the fact that production depends on consumption by the birds of things they wouldn't find scratching around in a traditional barnyard.

samcarter

@UlrikeFischer @PauloCereda Get well soon!

(no numbers on the scale as I don't know what a healthy duck temperature would be...) [@DavidCarlisle Please don't tell us the temperature for cooking]

Harald Hanche-Olsen

@samcarter A cooking thermometer would be inserted elsewhere, I am sure. I am not certain, but think I've read somewhere that birds' normal body temperature is a bit higher than what is good for mammals. Maybe around 40 °C or so.

David Carlisle

@UlrikeFischer I expect you intended to type yyyy and they came out as z by mistake

hola' to everybody

@egreg @DavidCarlisle hi

@ChristianHupfer Can I have your help?

egreg

@Sebastiano Ciao!

Sebastiano

@ChristianHupfer Dear Christian you know very well the structure "The legrand book".

I have created the table of contents and the preface with these rows of the LaTeX code:

%----------------------------------------------------------------------------------------
% TABLE OF CONTENTS
%----------------------------------------------------------------------------------------
\newpage

%\usechapterimagefalse % If you don't want to include a chapter image, use this to toggle images off - it can be enabled later with \usechapterimagetrue

@egreg Hi with affect and stime:)

@egreg My english is very bad. Can help me also you for my little question

@egreg Before that my battery is empty I need to set up my school's electronic register

Christian Hupfer

@egreg: Did you get that mail from our corollary friend?

Sebastiano

@ChristianHupfer Hi best phantom

Christian Hupfer

8:22 PM

@Sebastiano I know enough about The Legrand Orange Book Template to give the advise: Don't use it ;-)

@Sebastiano: And at the moment, the question is not clear to me

Sebastiano

@ChristianHupfer Can you see the pictures?

Johannes_B

@ChristianHupfer Agreed.

cfr

@PauloCereda :(

Christian Hupfer

@Sebastiano Yes, I can see them. The roman (or 'upper case' Roman) numbers should be achievable by \pagenumbering{roman} (or \frontmatter) for the Prefazione and later switch back to 'usual' arabic numbers

Sebastiano

@ChristianHupfer My pictures is clear?

@ChristianHupfer I have empty my battery. can you change my code please please?

@ChristianHupfer Tomorrow I will see your answer from my school

@cfr hi to you

@Johannes_B hi also to you

Christian Hupfer

8:30 PM

@Sebastiano No, I can't change it really, because I don't get what you are after here

Sebastiano

@ChristianHupfer I have not undestood

@ChristianHupfer I hope for your help also

hi to everybody my battery is empty

Christian Hupfer

@Sebastiano Two images that are vaguely connected are not really enough input for me in order to guess what you want there. The font information from the pictures is not relevant for me for the page number change (if that's the issue at all?)

samcarter

@HaraldHanche-Olsen Your estimate was very good! I found something that says 42.8\degree (books.google.de/…)

@DavidCarlisle That is the revolutionary new invention which helps to count points (or whatever one acquires during cricket) :)

@ChristianHupfer .... I should check which system Brazil uses - I don't want to freeze @PauloCereda

David Carlisle

@samcarter @PauloCereda thinks anything under 25C is freezing

Christian Hupfer

@samcarter I think it's Celsius, but I meant a version for our non-standard users ;-)

egreg

@ChristianHupfer Yes; replied but got no answer.

Christian Hupfer

@egreg I see. I don't understand his last paragraph however...

egreg

@ChristianHupfer Did you remove your answer because it went against my preferences? I don't think so

Christian Hupfer

9:00 PM

@egreg I think it was your first comment (below the question), about how to reference unnumbered corollaries for both theorems and propositions such that no other reader but the author of a book/article can exactly know which one is meant; I noticed this too late, that's why I deleted my answer. The second reason is, that I was not happy with my answer additionally

egreg

@ChristianHupfer Make him happy and undelete it.

Christian Hupfer

@egreg Well, he copied it before I deleted it and posted it (basically) again, but you know that. The copying/hijacking of a bad answer doesn't improve it ;-)

egreg

@ChristianHupfer I'm still convinced that numbering separately Lemmas, Propositions and Theorem is a bad service to readers. Publishers use it, but in many cases they force their in-house style over authors' preferences, so the fact that Herstein or Jacobson use that bad style is not significant.

CarLaTeX

@egreg I agree, from a poor student point of view!

egreg

@ChristianHupfer Corollaries are another thing, but “see the corollary to theorem 1.3” or “see corollary 3 to theorem 27.9” is rather silly. Oh, this poses a problem with cross references, because with a single corollary it is “the corollary”, with multiple ones the article should be omitted.

Christian Hupfer

9:11 PM

@egreg I basically agree with both of your statements, the more it is better to keep my answer hidden. The question should be deleted, in my point of view.

barbara beeton

@egreg -- i could comment on this, from the point of view that these days we have to think about ebooks, scrolling and hyperlinks. if only one corollary, it's a pain to make a link; can do it if you place an explicit anchor, but is this good enough? not sure that would be enough for him to figure he should withdraw the question, but is it worth a try?

egreg

9:42 PM

@barbarabeeton I think he misunderstood the sense of my comments: I don't like corollaries with “relative numbering”, but not as much I dislike separate numbering for the other type of statements. The book I always have in mind about this divides chapters into parts (sic!) and parts into sections; theorems, propositions and lemmas are numbered restarting by one at each section and, if there's only one of each type, it gets no number.

So a typical cross reference is “theorem in section 3 of part 2 of chapter 4” or, maybe, “corollary of theorem in section 3 of part 2 of chapter 4”. And the page header has just the chapter title (even without the number).

barbara beeton

@egreg -- oh, yikes! that arrangement is totally incomprehensible! recently, i had to critique a very long book with theorems, propositions, definitions, etc., that were numbered separately. it wasn't hyperlinked. it took a ridiculously long time to locate a particular definition with the numbering so disjointed. unless there's an index or list of such things, it's hopeless. book was intended for a textbook. pity the poor student.

i don't love the "number everything consecutively" style, but it sure makes it easy to find something.

egreg

@barbarabeeton The numbers are just labels, like house numbers. Yes, there are places like Tokyo where houses don't have numbers or Venice where the numbering is unique by “Sestiere”: the town is divided into six parts, houses are numbered starting from 1 in the center of the sestiere and going on following, as a general idea, a spiral. Nobody except postmen is able to find houses by numbers.

So you may see that a house is numbered 100, but the one round the corner could be 300.

barbara beeton

10:01 PM

@egreg -- true, but i'm not sure we should advocate for that. especially not in a textbook. (time to leave -- my chariot awaits.)

egreg

@barbarabeeton Beware it doesn't become a pumpkin!

David Carlisle

10:34 PM

@egreg house numbers, how advanced!

3

egreg

10:45 PM

@DavidCarlisle I guess that you don't need them in your big town.

David Carlisle

@egreg well I can find my house without them, but perhaps random van drivers wouldn't have to ask where various neighbours live every other day if there was some kind of system:-)
