Q: Why is Lisp useful?

GeekLisp obviously is an advantage for the AI stuff, but it doesn't appear to me that Lisp is any faster than Java, C#, or even C. I am not a master of Lisp, but I find it incredibly difficult to understand the advantage one would get in writing business software in Lisp. Yet it is considered as a h...

 
12:58 AM
@SeanAllred Yes, I've upvoted on of the answers there, so I assume I saw this question before.
Morning, folks.
 
1:11 AM
That should have been "one of the answers".
 
@FaheemMitha Good evening :)
 
@SeanAllred :-)
 
@FaheemMitha Time is a weird thing XD
 
Actually went to sleep at a reasonable time. Awake now. Coming up to 7 am.
@SeanAllred Time is a human construct. Like Lisp.
 
@FaheemMitha hehe yeah :)
 
1:25 AM
@SeanAllred -- have checked in-box and spam bucket; no message. am on laptop at home, but the interface is crippled (no linking in chat; have asked question about why and how to fix, but no suggestions forthcoming). the fire alarm was an accident, but when i held the door open for the full crews of an engine and ladder truck, the arsenal they were carrying was most impressive! anyhow, please try again!
 
@barbarabeeton You've been having quite an evening!
@barbarabeeton Sent. It's coming from an @gmail.com address, FYI.
 
oh, i left the office before the fire crews, so i don't know what finally happened, other than that nothing was burning. had a nice dinner, and am now starting to pack for a week on a barrier island on the georgia coast, "chasing alligators". (watch them and the rattlesnakes from a discreet distance. only sneak up on armadillos, geckos and horseshoe crabs -- much safer.)
 
@barbarabeeton That sounds lovely :) Do you know anyone who's not likely to keep the same discreet distance?
 
1:46 AM
@SeanAllred -- (no messages yet. very strange.) as far as rattlesnakes, in fact i do know someone. one of the naturalists who used to be on the island is a herpetologist, and he was always ready to make a dive for almost any snake -- he knew what he was doing; quite amazing to watch him dive into the bushes and come out with a black racer or a king snake. the nearest i've gotten to an alligator was when i found one (by the smell) that was maybe 10ft long, and quite dead.
somewhere i have a picture of me and the cleaned-up skull (now in the island's museum) staring at one another like hamlet and yorick. who knows what adventures await this year.
 
@barbarabeeton I wish I had the kind of gall necessary to work with snakes like that :) Must be rewarding work. And that's a large creature – I try to stick with animals smaller than me, dead or no :)
@barbarabeeton Maybe you can message me – try <tex (a) sean allred (dot) com>
Some serious thunder and lightning in Madison, WI…
My entire bedroom lit up through the blinds, and the thunder is still rolling from it…
@cfr I'm not sure I understand your comment, sorry :(
And you can add custom thingies. Also for the documentation to explain. But neat. — cfr 12 mins ago
Are you saying you think I should expand the answer?
 
@SeanAllred -- message sent, datestamp 21:54; hasn't been rejected ...
 
@barbarabeeton :)
 
cfr
2:23 AM
@SeanAllred No. Not really. It was just a comment. I can't remember what the thingies are called, though. I thought you might know but I'm not surprised that you can't tell.
 
@cfr Like the pdflatex {shell-escape: true} business? (I forget the exact syntax…)
 
cfr
@SeanAllred No. The things you create .yaml files for.
 
@cfr rules! :D (right?)
To be honest, I've never needed to create one… I'm guessing at the name
 
cfr
@SeanAllred Yes ;)!
I think so. But I think there's another bit as well. Hang on.
@SeanAllred Yes. Rules. And then there's a config file where you tell arara about the rules. I can't remember what they mean now. But I seem to have written a rule for metapost and add some thing to the config file for it. Anyway, yes, thank-you. Thingies = Rules ;)!
 
@cfr :)
 
cfr
2:32 AM
@SeanAllred It really annoys me when I can't remember the names of things ;). Or when I can only remember in the wrong language.
 
@cfr In a sense, I know exactly what you mean. I'm learning a distinct, mostly defunct variant of a programming language I know very well for a job – the differences are small, but they are many. Things I think exist don't and vice–versa.

Good maen
 
7:26 AM
List of people is building up, and there are some abstracts now :-)
Have to see if Will Robertson is going to make it (he tells me he hopes to)
 
8:14 AM
@JosephWright I'm not on the list yet but I will try to come too. It just depends on pressure with projects at work.
 
9:06 AM
@StefanKottwitz Indeed
@StefanKottwitz I've decided to make this one as I'm not sure when it will next fit in
 
9:57 AM
@JosephWright Why is the TeX lion holding a cellphone while kicking a ball, and why are there two suspicious bees flying around? :)
 
@PauloCereda and where's his cricket bat?
 
@DavidCarlisle oh indeed! :)
 
@PauloCereda I have a suspect in mind, I think a duck stole it...
 
@DavidCarlisle Oh no!
 
@PauloCereda: More important question: Why is it a lion and not a duck? ;-)
 
10:06 AM
@ChristianHupfer Exactly! :)
@ChristianHupfer: If I manage to host a TUG conference, I want a lion disguised as a duck. :)
@SeanAllred: featured WTF project of the day: github.com/mrkrstphr/illacceptanything
 
10:23 AM
@PauloCereda: I nominate you for TUG president ;-)
 
@ChristianHupfer are you sure that is wise?
 
@DavidCarlisle: Stupid men do stupid things ;-)
 
@PauloCereda @JosephWright see what happens to project management and overall design if things are moved to github?
 
@DavidCarlisle LOL
@ChristianHupfer ^^ wheeeeeeeeeeeee
 
@PauloCereda: I am not surprised :-P

Q: How can I escape a multicolumn environment

studentWhen using multicols from the multicol package, is is possible to do something like this: \begin{multicols}{2} Some text \begin{escapemulticol} Some large image or formula spanning the whole page width. \end{escapemulticol} Some other text \end{multicols} I need this in a more complicated ...

 
@DavidCarlisle LOL
Couldn't the OP end multicols, write what needs to be outside, then starts another multicols thingy?
 
@DavidCarlisle: One of your one-line answers again? ;-) Most probably from the stock answers too :-P
 
10:53 AM
 
@ChristianHupfer Das Kaktus!
 
hi
 
@Christoph Hello!
 
yo'
@PauloCereda :D
 
@yo' <3
 
yo'
11:07 AM
@PauloCereda I got my whiteboard home today!
 
@yo' Yay!
 
yo'
@PauloCereda I got a one-class-up and one-size-up for free due to delivery mistake
 
11:23 AM
@yo' woohooo
 
12:10 PM
@PauloCereda How's your fever going?
 
@egreg Thankfully I am recovering very fast. :) No more pain and the fever's gone. Now I'm drinking a lot of water for rehydration. :) And I eating a lot. :)

12:52 PM
@PauloCereda What's on the plates? Pasta? Steak? Salmon? Spinach?
 
1:16 PM
@Johannes_B Everything. :)
 
@PauloCereda Be careful not to eat the plates ;-)
 
@Johannes_B Oh no! :)
 
yo'
1:45 PM
@PauloCereda good to hear that, bud!
 
@yo' :)
 
2:33 PM
@DavidCarlisle Indeed
@DavidCarlisle Am currently on a day 'off', reading a book on Git and pondering things
 
2:46 PM
@JosephWright having fun with Git?
 
@JosephWright feeding ducks in a pond? :)
 
3:39 PM
@FaheemMitha Certainly an interesting read
 
4:32 PM
How much euros does a 1TB HDD cost?
 
@PauloCereda Depends on exact requirements, but I can find them for <£60
 
We should revive this:

Q: 404/CAPTCHA/Error images

JinI knew I forgot something right before the new design launch today. I didn't get a chance to create custom images for the 404/Captcha/error pages on the TeX site. Do you have any suggestions? A few examples from other sites: Cooking site's 404: Gaming site's CAPTCHA Photography site's ...

I think the problem with current answers are that they're all text-based, and the 404-error display is usually an image.
 
@JosephWright ooh

A: Competition time: Design an error page!

Paulo Cereda(with apologies to Don Knuth)

 
Compare with Stack Overflow's 404-page view:
...text as an image.
@PauloCereda Hmmm...
...we'll have to ping Jin.
:)
 
4:49 PM
@Werner ooh Jenga!
:)
 
5:33 PM
@JosephWright so reading your git book helped make a pull request? :-)
@egreg answer trumps comment:-)
 
@DavidCarlisle :-)
 
@egreg I think you are the one that would enjoy this the most play.lso.co.uk
 
@percusse do Ravel and Berlioz count as real composers for @egreg's somewhat restricted musical tastes?
 
@DavidCarlisle I would say crippled as he always wants to eat caviar and not enjoying a juicy hamburger with a cold beer :)
 
5:57 PM
@percusse ooh hamburger!
 
6:53 PM
@percusse Example of musical hamburger?

@Johannes_B Hilarious. That guy is a classic.
 
@Werner Sadly, i can relate with many of his toughts.
 
@Johannes_B He has a very logical way of thinking, so it's easy to relate to his discussions.
 
@Werner But sometimes, his train of thought is just ... hilarious.
@werner I know have seen this anymated, i just can't find it right now: youtube.com/watch?v=SVFT3wDEgYA
 
@Johannes_B :D
 
7:31 PM
Good maen...
 
@ChristianHupfer Hi
 
@Johannes_B: Förster :O
 
@Johannes_B That is the anode. You can get a much stronger x-ray beam out of the gallium then you can copper, molly or silver. Apparently you can get up to 20 or 30% of a syncatron.
 
@Canageek Wow, up to 30 percent? Amazing.
 
7:45 PM
@Johannes_B That is what I've heard.
@Johannes_B Bruker is quoting 3.5 × 10^11 X-rays/mm^2 -sec which would be 2 orders of magnitude stronger then a copper microsource.
@Johannes_B Three above a silver or molly source
 
@Canageek If our guys need lots of intensity, they travel to france for a few days and get some beem time at the syncatron in grenoble.
 
@Johannes_B Yeah, we submit crystals to a syncatron in the US, and have talked about going to the National Light Source, but we'd like to do real-time monitoring of reactions.
 
8:03 PM
@daleif: Check this out...
 
@Canageek Real time monitoring of reactions sounds interesting. What kind of reactions?
 
@percusse Well, if they change the program to host real music…
 
@Johannes_B Gas sensing reactions. One of my groups areas of study is sensing dangerous compounds
 
8:37 PM
@Canageek I have to admit, that i have absolutely no clue in that area. :-/

@PauloCereda Did you like the increasing emphasis: Never everNever everNEVER EVER?

@egreg ooh :)
 
10:18 PM
@egreg good thing the site doesn't use Garamond... ;-)
I can just imagine Ben Hur riding his chariot up to a Rolex dealer and walking in. :-)
 
@PaulGessler :)
 
10:30 PM
Hi. Does a math environment like flalign exist where I don't have to use ampersands on both sides of each line to align it to the left? E.g. where this is automated completely?
 
@egreg would it be OK if I redefined \fi ?
 
@DavidCarlisle If you're able to do it not breaking LaTeX,…
 
@egreg \let\tex_fi:D\fi\let\fi\undefined sounds like a good plan....
@1010011010 putting & on both sides of an equation sounds like abuse of teh environment:-)
 
@DavidCarlisle \RequirePackage{xor}
@1010011010 Just use align
 
@egreg Wouldn't it then be center aligned rather than flush left?
 
10:39 PM
@1010011010 flalign is full length align, not flush left align.
 
Oh... oke
 
@1010011010 If you want flush left displays, use the fleqn option to amsmath.
 
@1010011010 use [fleqn]
 
Ah, excellent. Yes that works nicely.
This also circumvents the need of building a new math environment. Thanks. This was way easier than I thought, haha
@DavidCarlisle What's a good example in which the environment is not "abused"?
 
@1010011010 not sure what you mean. One in which there isn't a &at the start and end:-)
@1010011010 texdoc amsmath bottom of page 4
 
10:46 PM
I see. Fair enough.
 
@1010011010 See tex.stackexchange.com/search?q=flalign+user%3A4427 (most of the answers tell not to use flalign).
 
@1010011010 note if you have just & stuff & then you are typesetting just the right hand side of the first equation in the line. It sort of almost works as a full equation, set flush left but not really, for example if you start an expression with an infix operator or relation it loses its infix spacing compare ${}+2$ to $+2$ the ams alignments all add {} at the start of the right hand side so that it works as a continuation of the left had side a&=b the = gets infix spacing.
 
@egreg I've never had issues with flalign. The spacing is pretty predictable the way I used it...
 
11:21 PM
Thank you both, I guess my issue was trivial. :-) Night.
