« first day (2176 days earlier)      last day (1157 days later) » 

7:25 AM
On the Park and Ride going into Oxford
 
@JosephWright All of you, have fun at the user meeting.
 
@JosephWright you have mail:-)
 
@DavidCarlisle Sorted, but that must be from an earlier change ...
 
Can somebody tell me what to do in such situations? latex-community.org/forum/viewtopic.php?p=96750#p96750
 
7:49 AM
@DavidCarlisle Found the first place that \protected will be used :) (\TextOrMath): if we make \DeclareRobustCommand use e-TeX of course that can be simplified
 
8:17 AM
On the bus
@JosephWright not safe I suspect
 
9:07 AM
People collecting up
 
@JosephWright There are so many packages that rely on the current implementation of \DeclareRobustCommand, unfortunately
 
@egreg Yes, @DavidCarlisle and I have just had exactly that conversation
@egreg I was thinking about the internal \foo<space> macro that really cannot be safety expanded
@egreg \edef\l@ngrel@x{\l@ngrel@x\protected}
 
@JosephWright That could be interesting
 
@egreg Yes, not sure it's safe, but will explore options: I'm thinking of 'just before \futurelet'
 
10:06 AM
@barbarabeeton Thank you! <3
 
yo'
10:29 AM
@egreg got 90 math.se rep very quickly, simply for answering the questions that should have been asked. Feels great :-)
 
@yo' :) One from me
 
yo'
@egreg oh rly? :-)
I wonder which one it was...
 
Impressive talk from @StefanKottwitz
 
10:47 AM
@JosephWright Cool! Are you recording?
 
@PauloCereda Yes, I've got sound for @StefanKottwitz. I'm going to have to re-record my own talk (messed up pressing a button)
 
@JosephWright Oh no!
@Joseph: in other news, if you feel like allocating me in an earlier timeframe, feel free. :)
I am already ready. :)
 
@PauloCereda OK
 
11:24 AM
Oh boy, I am nervous. :)
 
 
2 hours later…
1:42 PM
Quack!
 
@PauloCereda Hello
 
@JosephWright How's the meeting?
 
@PauloCereda Good so far
 
@JosephWright Yay!
 
1:57 PM
@PauloCereda we had Pizza for lunch, horror no pineapple
 
@DavidCarlisle oh no!
 
yo'
@DavidCarlisle trying to please @egreg ?
 
@David: which side did you pick in the chocolate thingy? :)
 
@DavidCarlisle Everybody knows that real pizza should have onions, tuna and pineapple!
3
 
2:22 PM
@egreg -- no anchovies?
 
 
1 hour later…
3:30 PM
@barbarabeeton Only if you also add coconut.
 
4:22 PM
Meeting over, time to write up all the things
@StefanKottwitz Really excellent talk today
@StefanKottwitz I'll try to merge the sound and slides to make a video
Ah, @DavidCarlisle
 
@JosephWright hello, I got home:-)
 
4:38 PM
@DavidCarlisle Looks almost like a pizza
 
@egreg underfull one, don't mind too much but probably it would have been good to have a specific question about that message rather than the general underfull h or v box one.
 
@DavidCarlisle I saw that the \\ problem was explicitly mentioned also in the other answers. Probably it's also somewhere else, better not scattering information.
 
@egreg yes perhaps.
 
 
3 hours later…
7:26 PM
     \def\newlanguage  {\e@alloc\language \chardef{\count19}\m@ne\@cclvi}
Incidentally, LuaTEX allows 16383 separate languages,
@JosephWright ^^^^^ spot the error!
@StefanKottwitz nice talk, thanks
 
@DavidCarlisle What did I get wrong now?
 
@JosephWright me actually
 
@DavidCarlisle Ah, phew
@Canageek You got referenced in my talk :)
 
@DavidCarlisle @JosephWright Thank you! It's fun to speak about work with TeX friends!
 
@JosephWright not sure if it has changed but 16383 in roman numerals isn't cclvi
 
7:28 PM
@DavidCarlisle Ah, of course
 
@JosephWright I feel an @e@alloc@language@top coming on...
 
7:54 PM
@DavidCarlisle I guess, though practically not that useful ...
 
8:06 PM
@JosephWright I was looking as I was having a thought that could double the language use (and if we loaded the t1 patterns that would be more as well....)
 
@DavidCarlisle Ah, right
 
yo'
@DavidCarlisle \mathchardef\@mmmmmmmmmmmmmmmmccclxxxiii="3FFF?
 
@yo' \e@alloc@top
 
yo'
@DavidCarlisle that's cheating on the cs names :-)
 
$ latex '\makeatletter\show\e@alloc@top'
This is pdfTeX, Version 3.14159265-2.6-1.40.17 (TeX Live 2016) (preloaded format=latex)

or rather
$ lualatex '\makeatletter\show\e@alloc@top'
This is LuaTeX, Version 1.0.0 (TeX Live 2017/dev)

hmm OK it's half that grr why can't they make all the registers have the same range
 
yo'
8:18 PM
@DavidCarlisle well, I've always wondered why int means so many different things on different computers. I start to understand...
 
This is LuaTeX, Version 1.0.1 (TeX Live 2016/W32TeX)
@DavidCarlisle ^^^^
 
anybody... how can you tell the top language without looking at the sources of *tex-the-program?
\setbox0\vbox{a \language30000000 b} \showbox0
^^^ isn't an error even in classic tex
ah use setlanguage and see what language node gets set...
` \setbox0\vbox{a \setlanguage30000000 b} \showbox0`
makes
..\tenrm a
..\glue 3.33333 plus 1.66666 minus 1.11111
..\setlanguage0 (hyphenmin 2,3)
..\tenrm b
@JosephWright I guess I need to build again, any new primitives?
 
@DavidCarlisle That's the one I used to update expl3
 
Updated to revision 6159.
here we go....
 
8:37 PM
Lots of post-AGM actions are marked 'JAW'!
 
@JosephWright sounds perfectly reasonable to me
This is LuaTeX, Version 1.0.1 (TeX Live 2017/dev)
@JosephWright ^^
 
@DavidCarlisle :)
@DavidCarlisle, @StefanKottwitz Wondering whether to make a video from Stefan's talk or just post the audio and slides (rather a lot of slides for me to run in 'by hand')
 
just remaking all the luatex formats just in case..
 
9:01 PM
@JosephWright We want the video :-)
 
@Johannes_B Yes, but it's quite a lot of work (I have to take the audio and work out where each of the slides goes ...)
 
@JosephWright So there is no video of Stefan talking? Then the audio would be enough, i guess.
 
@Johannes_B I don't have the hardware to capture someone else's screen, so I have to combine audio with static slides
 
9:26 PM
@JosephWright Ok. Just wondering if there is a video/photography club at the university which can help out with stuff like that.
 
@Johannes_B Kaveh has the tech but he's been busy. I could sort it out, I guess: it's just a question of whether we want to spend the money. Normally it's easier just to present from one machine ...
