Hello! I've just ask a question here:(tex.stackexchange.com/questions/388410/…), and I would like you to give me a hand! Thanks in advance.

@egreg Do you see any useful answer for tex.stackexchange.com/questions/387465/…?

CarLaTeX

8:02 AM

@PauloCereda I'm very clever ^^^ :):):)

TeXnician

@CarLaTeX @PauloCereda's output principle: Much ado about nothing ;)

CarLaTeX

@TeXnician LOL

TeXnician

@CarLaTeX That's probably why his thesis has more than one page :D

CarLaTeX

@TeXnician ROFL

@PauloCereda A tip for the documentation: put before skip = 16pt, (with the value you want) in the setting of your tcolorbox with the title, they look too close to the text, in my opinion :)

Paulo Cereda

10:07 AM

@TeXnician you guys know me very well. :)

@TeXnician: it's very verbose so people don't need to read documentation. :D

@DavidCarlisle oh no

TeXnician

@PauloCereda That's why it reminded me of Shakespeare. Very verbose, but at the end everything quits (or dies) without helping anyone...

Christian Hupfer

@PauloCereda People do never read documentation...

Paulo Cereda

@DavidCarlisle ooh I have this duck

@TeXnician :)

@TeXnician speaking of "everybody dies", I think I was near a cinema during the exhibition of "Marley and me". One dude graffitied the poster with O cão morre! (The dog dies!), which we terrible for everybody who was going to watch the film!

So... McGregor lost, huh?

Christian Hupfer

@PauloCereda Reminds me of the Simpsons episode where Homer leaves the cinema after watching "Empire strikes back" telling something "who thought that Darth Vader is Luke's father" aloud and anybody is annoyed outside ;-)

Paulo Cereda

10:23 AM

@ChristianHupfer ooh I remember that one! It was pure gold!

WAIT A MINUTE, IS THAT TRUE?!

Oh no!

Christian Hupfer

12:29 PM

@TeXnician: Why did you delete your solution?

TeXnician

@ChristianHupfer Well, because I basically wanted to add the same example to it as you did (tcb mechanism). But my lunch break took too long (you did answer meanwhile).

Christian Hupfer

@TeXnician Sorry, I did not want to interfere with your idea -- I thought you would use the OP code and make it more failsafe, not firing with the full tcolorbox cannon ;-)

TeXnician

@ChristianHupfer Well, that was in my initial comment under the OP. The OP's code example was too "hacked-together-solution-like" in my view.

Christian Hupfer

@TeXnician I saw that comment, yes. I don't like such \newcommand wrappers around the tcolorbox mechanism

TeXnician

@ChristianHupfer Yeah, me too. tcb is too mighty to use this kind of workarounds ;)

Christian Hupfer

12:37 PM

@TeXnician \let\swissknife\tcb ;-)

TeXnician

@ChristianHupfer Oh, a verbatim-safe, robust and omnipotent swiss-knife.

@ChristianHupfer I have undeleted my answer (but adapted to a non-tcb version).

Christian Hupfer

@TeXnician I have negatively downvoted it ;-)

TeXnician

@ChristianHupfer \def\upvote{\not\downvote}\def\downvote{\addtocounter{votes}{-1}}. What does \not do? :D

@Johannes_B -- some good, some bad. (speed of completion, good. overbloated mailers, that don't allow for saving and editing in-message content, BAD! oh, how i yearn for a nice text-only mailer again!)

Johannes_B

@barbarabeeton A bit more of text-only would be great. Too much stuff going on on websites, i think.

Paulo Cereda

3:46 PM

@DavidCarlisle: out of curiosity, do you use emacs with -nw?

David Carlisle

4:02 PM

@PauloCereda sometimes, or sometimes use emacs on a system with no X, which comes to the same thing,

Johannes_B

@DavidCarlisle I am not a reliable person when it comes down to this. chat.stackexchange.com/rooms/64504/…

David Carlisle

@PauloCereda less so than i used to even a year ago, connection from home used to be such that it was easier to ssh in over a terminal connection and run a windows-free emacs at the other side, but since I have fibre to the house now it's more convenient to run an X-windows emacs on the remote machine

@Johannes_B I saw that. but decided to let it drop.

@Johannes_B vvv

@p procedure scan_file_name;
label done;
begin name_in_progress:=true; begin_name;
@<Get the next non-blank non-call...@>;
loop@+begin if (cur_cmd>other_char)or(cur_chr>255) then {not a character}
    begin back_input; goto done;
    end;
  if not more_name(cur_chr) then goto done;
  get_x_token;
  end;
done: end_name; name_in_progress:=false;
end;

@ The global variable |name_in_progress| is used to prevent recursive
use of |scan_file_name|, since the |begin_name| and other procedures
communicate via global variables. Recursion would arise only by

Paulo Cereda

@DavidCarlisle cool. :)

David Carlisle

4:18 PM

@PauloCereda oddly I never use vim that way (if I ssh to a machine that's got vi but not emacs I usually log out:-)

Paulo Cereda

@DavidCarlisle you are mean. :)

@DavidCarlisle: the few times I used emacs I had to have the evil plugin activated.

Harald Hanche-Olsen

@DavidCarlisle My personal preference is to use a local emacs always. To edit a file on a remote system, I mount the remote filesystem with sshd. Some would rathter use tramp, but I haven't bothered to learn it.

David Carlisle

Jun 29 at 16:15, by Paulo Cereda

@DavidCarlisle you are not mean :)

@HaraldHanche-Olsen not sure I can do that (usually local machine is windows/cygwin and remote is linux but I may not have mount access)

Johannes_B

@DavidCarlisle Thanks, i put a link into the other room.

Paulo Cereda

4:34 PM

@DavidCarlisle: this might surprise you: my configuration left emacs almost a copycat of vim. :)

Harald Hanche-Olsen

@DavidCarlisle Ah, the local machine will pose a problem. Mount access is not: If you have ssh access, you can mount the filesystem with sshfs. Provided your local machine supports it, of course.

… must … not … start … operating system rwar …

Paulo Cereda

@HaraldHanche-Olsen ooh let's do it

:D

Harald Hanche-Olsen

@PauloCereda I haven't seen one yet that ends well.

David Carlisle

@HaraldHanche-Olsen don't argue with paying customers:-)

Paulo Cereda

@HaraldHanche-Olsen That's the fun of it

Harald Hanche-Olsen

4:39 PM

@DavidCarlisle If they pay well, no, I suppose.

wget

5:57 PM

Ok. Back. I debugged most of the issues I was experiencing with my class, resulting from the upgrade to TexLive 2017.

I customized the way header and footers were generated, depdning on several options passed to my class. However, I realized as soon I try to add a chapter, the page that follows the chapter declaration has its headers removed and replaced by the name of the chapter.

Do you know what could be the cause of that?

According to the fancyhdr man pages, each time a chapter (or any LaTeX command dedicated to titles) is called, the \maketitle command is called and the \thispagesty…

Christian Hupfer

6:23 PM

@wget: I remember that fancyhdr was updated some months ago, but as far as I can remember there were no dramatic changes

wget

7:22 PM

Ok it seems this is due to the chaptermarks.
However, disabling them doesn't solve the problem :-/

David Carlisle

@wget get a fancyhdr from tl2016 and try with that to confirm that is the change, if so it's easy enough to just compare the two and see what changed

Christian Hupfer

7:42 PM

@Sebastiano: Why should I edit your question in order to clearify it? That's your job ;-)

Sebastiano

7:59 PM

@ChristianHupfer Hi :) I not speak english well.

@DavidCarlisle Hi, David

@ChristianHupfer If the downvote problem is due to my bad English help me. I tried to do just a few minutes ago of my best to clarify the situation

@ChristianHupfer For my question of the eyes is there a reason for downvote?

Christian Hupfer

@Sebastiano I haven't downvoted it. Who ever has done so seems to have issues with the question but I can't speak for him or her.

David Carlisle

@Sebastiano I didn't downvote but you have been on the site long enough to know that is a very poor question. It just has a fragment of code that no one can run with a link to some external site that possibly has a zip file for the class. You should have done the work to make a self contained example.

Christian Hupfer

8:15 PM

@Sebastiano: One issue with some (or many) of your questions is that you do not say clearly what you have in mind, post fragments, change them a lot of times and in the very end the whole question is contradiction itself. If I want to fly to Moscow, I don't fly to Paris / London / New York/ Toyko and Wladiwostok to end up in Moscow, but this how some of your questions look like ...

David Carlisle

@ChristianHupfer interesting trip, you should try it!

Christian Hupfer

@DavidCarlisle I forgot the stop in Oxford, I assume ;-)

CarLaTeX

@ChristianHupfer @DavidCarlisle We missed @Sebastiano, the chat was dull without him!

Christian Hupfer

8:30 PM

@CarLaTeX By the way: Where's Moriambar?

CarLaTeX

@ChristianHupfer I saw him on chat few days ago, he said he was busy...

David Carlisle

@ChristianHupfer in Hawaii, eating pizza

Christian Hupfer

@CarLaTeX Ah, I was busy recently and had no time for chat...

CarLaTeX

@ChristianHupfer It's holiday time in Italy :)

Christian Hupfer

@DavidCarlisle Pizza Maui? ;-)

@CarLaTeX I see... it's still holiday time here and uncomfortably warm...

CarLaTeX

8:35 PM

@ChristianHupfer Don't tell me! 37°C today in Milan toooooooo hoooot

(Sebastiano's style)

Christian Hupfer

@CarLaTeX Well, for me 25°C is already ways too hot, but we have 32°C right today (which is of course better than 37°C)

CarLaTeX

@ChristianHupfer I don't remember such a temperature at the end of August in Milan in all my life!

barbara beeton

@ChristianHupfer -- golly, it's like fall here already! last night, i needed a blanket, and the furnace kicked on. (59F, 15C when i woke up.) tonight, i guess we'll have to close the windows! at least, no hurricane here ... yet ... the season usually starts later here in the northeast.

Johannes_B

@CarLaTeX ;-)

David Carlisle

I should explain for those not versed in strange versions of English, that "fall" is "autumn" in English.

CarLaTeX

8:46 PM

@DavidCarlisle I knew it, I visited Vermont during the Indian Summer some years ago :)

@barbarabeeton I could send you 10 of my degrees ;)

David Carlisle

@CarLaTeX shh I just need to irritate @barbarabeeton from time to time (think of it as an analogue of pineapple pizza:-)

CarLaTeX

@barbarabeeton BTW, you got mail :)

@DavidCarlisle You're a funny joker :)

wget

9:05 PM

@DavidCarlisle after further testing, I reinstalled a 2016, then 2015 and it seems the bug was already there before. It doesn't seem to be related to TexLive bug rather with a combination of other plugins. Since I have been only utilizing git for LaTeX for a short time, I'm unable to bisect the issue :-/

It seems like this behavior is the default due to the way \chapter marks are working in combination with fancyhdr

barbara beeton

9:30 PM

@CarLaTeX -- got it. working on it. (and i can annoy @DavidCarlisle just as effectively as he tries to annoy me. we've had a lot of practice! but we're polite, and it never devoves to shouting or swearing or name calling.)

Does anyone know anything about SSDs? I'm trying to choose one and, for some reason, an unspecified-brand drive of the same size is more expensive than an Intel-brand drive. Since branded stuff is usually more expensive, I'm wondering what is wrong with the Intel drives ....

@DavidCarlisle You remember that you explained how to fix texdef.pl so that it works with current perl? I'm wondering if you could tell me how to fix it properly. Right now, it works great with texdef <something> but texdef -s <something> fails, for example. Let me know if you'd rather I asked a new question.

@PauloCereda SSDs you mean? I know. Last time I was looking for a laptop, they were an expensive temptation. This time, I'm considering it. This from Lenovo's user guide for a laptop:

> For your safety, always follow these basic precautions with your computer:
> • Keep the cover closed whenever the computer is plugged in.

Paulo Cereda

@cfr I am... lost!

cfr

@PauloCereda Maybe it is a 'see no evil, hear no evil, speak no evil' thing? Given the content and potential of an internet-enabled device, the safest thing is never to actually use it? They also say that you should avoid using the keyboard for an extended period of time.

> ... be careful not to use the keyboard for any extended length of time.

Paulo Cereda

@cfr I am really lost. :) Maybe they don't want us to use their machines! :)

cfr

@PauloCereda <3

Paulo Cereda

@cfr <3

@cfr I have a Dell laptop

cfr

11:26 PM

@PauloCereda How is it? I've been looking at Lenovo, HP and Dell ... mainly. Dell's keyboards put me off.

Paulo Cereda

@cfr I have four Dell machines total: 2 desktops and 2 laptops. My laptops are an Inspiron 1545 (fantastic machine, even with an old hardware -- running Fedora 26 64bits at full force), and a Vostro 5480 (new, ultrathin). I agree that Dell keyboards are terrible, at least the desktop ones (no one beats Microsoft hardware for keyboards), but the laptop ones are nice, even the ultrathin version.

@cfr: I must point out that the battery life is insane. I can easily work close to 6 hours when in the shaky bus (of course, in economy mode and with wireless and bluetooth turned off, and then I usually have a big black terminal screen in front of me with a vim session).

cfr

@PauloCereda I read that they were a bit spongy. Lenovo's keyboards are nice. (Also, I don't have to have a UK keyboard this way.) The ultrathin ones are lovely. They just can't connect to anything else ;).

Paulo Cereda

@cfr My Inspiron has the best keyboard I've ever seen, at least for a laptop. :)

cfr

@PauloCereda The x270 is supposed to get up to 21 hours. I don't believe that, but it is supposed to be very good with the 6-cell.

@PauloCereda Have you ever tried a ThinkPad keyboard?

Paulo Cereda

@cfr Holy cow! 21 hours? I can travel to UK and come back without the need of recharging it! :D

@cfr Never used it, but I hear good things about it (a friend of mine has it). Lenovo hasn't a big share in Brazil.

cfr

11:39 PM

@PauloCereda For some reason a 6-cell 47WH battery is the cheapest, then the 3-cell 23WH batter, with the most expensive being the 6-cell 72WH one, which is the one which is meant to get up to 21 hours. (There's also a built-in battery. I don't know why it is like this.)

Paulo Cereda

@cfr Oh my!

cfr

@PauloCereda I have an X121e right now, but the HDD is dying and it really isn't worth buying a new one for a machine of this age. (Laptop-wise, it is ancient.) I guess with Brexit it is proving rather more expensive than last time, no matter what I go with. I essentially have one seriously usable machine at a time. That is, I still have 2 older laptops, but one is not very usable and the other is almost unusable. (Certainly unuable as a laptop.) I've never considered having two machines of my own.

@PauloCereda The configuration is really confusing though. To think, I started this as a hypothetical 'what if ...?' exercise!

@PauloCereda Lenovo's customer service, on the other hand, is beyond dire. (But the local warranty-service people are pretty good.)

Paulo Cereda

@cfr Are brands like Acer acceptable? They seem to have interesting hardware at affordable prices around. Also, when I buy computers, I usually ask for an OS-free version (or the ones who come with... Ubuntu *argh).

@cfr Ah Dell is the other way around. I think Sells is terrible, but support is very good.

@cfr Which OS does your laptop run? Arch?

cfr

@PauloCereda Yes. But I will almost certainly have to buy Windows, even though I won't (ever) use it :(. My problem really is that I like small laptops. I have 11.6" now. The X270 would be 12.5". At a stretch, I'm considering 13", but a lot of good value deals are 15"+ and, by my standards, that's enormous.

Paulo Cereda

Oh my, @AlanMunn is doing something on GitHub! #stealthduck

@cfr Really? Oh my, I cannot stand laptops with screens smaller than 14". :) The only exception is my dad's Aspire One from Acer which seems very handy in general, and I will steal that machine one day and install a nice OS with a big black screen. :)

@cfr 15" is the biggest I can handle, for a laptop. For desktops, 21" is the limit.
