i.stack.imgur.com/njHUK.png is it correct for depicting the number hierarchy from natural to complex numbers?
 
user19161
6:52 AM
@ガベージコレクタ What is I?
 
user19161
@ガベージコレクタ Note that there are two definitions of the naturals in use: one includes 0 and the other excludes 0.
 
user19161
@ガベージコレクタ I don't think I is a standard symbol whatever you may mean with it.
 
ガベージコレクタ
ガベージコレクタ
7:11 AM
@JasperLoy: it is my drawing for number hierarchy from natural to complex sets.
@JasperLoy: So what is the standard symbol for imaginary set?
@JasperLoy: Also what is the standards symbol for irrational set?
 
user19161
@ガベージコレクタ I do not know of any standard notation for irrational numbers or purely imaginary numbers (complex numbers with zero real part).
 
ガベージコレクタ
ガベージコレクタ
@JasperLoy: OK. Thanks. I will be in Singapore tomorrow. Do you want to meet me? :-)
 
user19161
@ガベージコレクタ You can just use R-Q to represent irrational numbers and Ri to represent purely imaginary numbers, since they are real numbers that are not rational numbers and real numbers multiplied by i respectively.
 
user19161
@ガベージコレクタ Hmm, let me think about it.
 
ガベージコレクタ
ガベージコレクタ
@JasperLoy: No. I have no confidence. :-)
 
user19161
7:24 AM
@ガベージコレクタ What is this confidence thing about? Are you like extremely shy or something?
 
ガベージコレクタ
ガベージコレクタ
@JasperLoy: Exactly.
 
user19161
@ガベージコレクタ Oh OK, then never mind.
 
ガベージコレクタ
ガベージコレクタ
@JasperLoy: Did you study in NUS?
or NTU?
 
user19161
@ガベージコレクタ Yes, but let's not talk about that now. =) Anyway, I am glad you like pstricks too, like me!
 
ガベージコレクタ
ガベージコレクタ
I want to master PSTricks and plain TeX first then TikZ as TikZ is necessary for annotations in documents typeset by pdflatex.
i need tikz just for annotation purpose.
 
user19161
7:29 AM
@ガベージコレクタ I am content with knowing LaTeX.
 
ガベージコレクタ
ガベージコレクタ
@JasperLoy: What does it mean?
@JasperLoy: Oh i see. the content has different meaning.
 
user19161
@ガベージコレクタ I mean I am happy just knowing LaTeX and don't need to know plain TeX.
 
ガベージコレクタ
ガベージコレクタ
@JasperLoy: It is not enough for package writers.
@JasperLoy: I will creat a package named JasperLoy :D
 
user19161
@ガベージコレクタ By the way, it seems to me that most people doing set theory include 0 as a natural number. It's more convenient that way. Bourbaki also includes 0. I also like to include it myself. But some people equate the natural numbers to the positive integers.
 
user19161
@ガベージコレクタ I still don't understand why I am special to you. I am nobody, just someone with a tragic story which I shall not reveal here. =)
 
ガベージコレクタ
ガベージコレクタ
7:34 AM
@JasperLoy: I see. Are ...,-4,-2,0 even numbers?
@JasperLoy: I also don't understand.
 
user19161
@ガベージコレクタ Well, it all depends on what definition you want to use. If one is working with the positive integers only, even would mean 2,4,6,... . If one is working with all integers, even could include the negative counterparts as well.
 
user19161
@ガベージコレクタ Maybe we knew each other in a previous life and share a kammic connection. =)
 
ガベージコレクタ
ガベージコレクタ
@JasperLoy: Maybe. :-)
@JasperLoy: Singapore mathematics books seem to be well-written.
 
user19161
@ガベージコレクタ I might share more with you in future via email, and I hope you do so as well.
 
ガベージコレクタ
ガベージコレクタ
@JasperLoy: I will meet you in the future TeX conference in Singapore :-)
 
user19161
7:38 AM
@ガベージコレクタ I have no comments on that. =)
 
ガベージコレクタ
ガベージコレクタ
@JasperLoy: Have Singapore been the TeX conference place ?
@JasperLoy: Why did you leave?
 
user19161
@ガベージコレクタ No idea, and I don't care. I don't like to live here, but I shan't say more. OK, I am off. See you!
 
ガベージコレクタ
ガベージコレクタ
@JasperLoy: you can live in Bali, Indonesia.
@JasperLoy: Do you want to teach mathematics in a high school ?

@JosephWright You got mail. :)
 
egreg
egreg
@PauloCereda Are your slides available? By the way, I have strong objections on your pronunciation of "frontespizio". :)
 
Paulo Cereda
Paulo Cereda
@egreg Uh-oh. :) I'm sorry, I'll improve my pronunciation. :) Joseph will add the slides together with the audio in a video, but I'll send you the slides right now. :)
 
Joseph Wright

Paulo Cereda
Paulo Cereda
@JosephWright ooh! :)
 
Joseph Wright
Joseph Wright
I'm going to work on the talks one at a time, and also try to find somewhere to host them!
I might start with the ones with no slides :-)
 
Paulo Cereda
Paulo Cereda
9:36 AM
@JosephWright How about an Youtube or Vimeo account for UK-TUG? :)
 
Joseph Wright
Joseph Wright
@PauloCereda Might work

@JosephWright One of the first editors I used on the Mac had the peculiar habit of adding mysterious characters from time to time, so there was the "Zap Gremlins" menu entry.

Audio/video processing may take a while: I need to play things through a few times, so it will need a few days for me to do everything
I did not quite get the mic set up right, by the look of things, so not all of the sound is quite how I wanted it :-(
Listening back to some random selections, the sound is not too bad. Which talk do people want me to process first?

David Carlisle

10:11 AM
@JosephWright well not :-) I think that's probably the most widely relevant talk at present time the Pi ones may be the future (or may not:-) and mine was the ramblings of an old-timer...
 
Joseph Wright
Joseph Wright
@DavidCarlisle The Pi ones have no video, so I need to come up with some 'filler'
 
David Carlisle
David Carlisle
@JosephWright You could use the video that Simon showed from his Pi....
 
Joseph Wright
Joseph Wright
@DavidCarlisle I'll start with @PauloCereda's then. I need to run it through twice I guess, once to clean up the audio and a second time to add the video.
@DavidCarlisle :-)
Vimeo account established: vimeo.com/uktug
No videos yet: other things to do this morning

@stefan I saw your book. I hope the publisher chooses nicer fonts for the next edition. =)
 
Paulo Cereda
Paulo Cereda
12:12 PM
@JosephWright Don't worry! :) I'll process them with Audacity, may I? :)
 
Joseph Wright
Joseph Wright
@PauloCereda You'll want the raw data uploading to Dropbox, then?
 
Paulo Cereda
Paulo Cereda
@JosephWright Yep, I'll use them. :)
@JosephWright: could you give me the link to the other audios? :)
 
Joseph Wright
Joseph Wright
@PauloCereda I'll upload one at a time and let you know
 
Paulo Cereda
Paulo Cereda
@JosephWright Ah OK. :) I'll work with mine and David's. :)
 
user19161
So how was the talk for everyone? Good? I hope the food was good!
 
Joseph Wright
Joseph Wright
12:20 PM
@PauloCereda Upload proving a bit tricky
 
egreg
egreg
@DavidCarlisle Your wellcome.
 
Stefan Kottwitz
Stefan Kottwitz
@JasperLoy Well, it's the font used in the whole series of his beginner's guides, no exception just because the content is about LaTeX. I hope the publisher will decide not to use low res bitmap images for printing next time instead of provided pdf files.
 
user19161
@StefanKottwitz Oh OK. Next time choose another publisher. =)
 
user19161
@egreg Sorry to interrupt your theorems, but it is "welcome". =)
 
egreg
egreg
@JasperLoy Look at the referenced line. :)
 
user19161
12:34 PM
@egreg Oh...
 
Stefan Kottwitz
Stefan Kottwitz
@JasperLoy That's clear, it's already decided :-)

@JosephWright: uploading new David's mp3 to my Dropbox account. :)
We could get some funny bits of all talks and make an autotune!
Or a ringtone!

@egreg ooh! :)
@JosephWright: dl.dropbox.com/u/74558210/David-Carlisle2.mp3 Is this version a little better? :)

I'm working on @PauloCereda's recording. I've done the audio clean-up, now doing the screen recording, will then recombine the two!
 
Paulo Cereda
Paulo Cereda
@JosephWright Is it working? :)
 
Joseph Wright

3:27 PM
@PauloCereda Slides recorded: now need to install iMovie and do the merge
 
Paulo Cereda
Paulo Cereda
@JosephWright Which Mac version are you using? :)
 
Joseph Wright
Joseph Wright
@PauloCereda 10.7.5
 
Paulo Cereda
Paulo Cereda
@JosephWright I think you might already have iMovie. :)
 
Joseph Wright
Joseph Wright
@PauloCereda No
@PauloCereda Might have been on the DVD, but that was for a previous OS X version
 
Paulo Cereda
Paulo Cereda
@JosephWright I see. Maybe it's free in the Apple Store.
 
Joseph Wright
Joseph Wright
3:31 PM
@PauloCereda £10.50
 
Paulo Cereda
Paulo Cereda
@JosephWright Oh no!
:(
My ML came with iMovie, that's why I thought it would be a default thing.
 
Joseph Wright
Joseph Wright
@PauloCereda Like I said, I had the DVD version for 10.5, but I suspect that won't work with 10.7
Still have it, in the box, of course
 
Paulo Cereda
Paulo Cereda
@JosephWright :(
Sorry for suggesting iMovie. :(
 
Joseph Wright
Joseph Wright
@PauloCereda It's fine
@PauloCereda I'm happy to try this out
Importing slides now: may need to try to deal with one glitch (I made one mess-up changing the slides)
Can you grab from video camera direct to iMovie?
 
Paulo Cereda
Paulo Cereda
@JosephWright I think so, iMovie has something called Events, where you organize your videos.
The sounds are managed by iTunes.
 
Joseph Wright
Joseph Wright
3:46 PM
@PauloCereda How exactly do I add the audio?
 
Paulo Cereda
Paulo Cereda
@JosephWright You need to import it to iTunes first, then it will be available in iMovie.
 
Joseph Wright
Joseph Wright
@PauloCereda I have it in the iTunes list, but trying to drag onto the 'events' fails
Ah, got it!
 
Paulo Cereda
Paulo Cereda
@JosephWright I forgot to mention, it's another panel. :)
I'm sure you'll like iMovie. :)
 
Joseph Wright
Joseph Wright
Creating first movie now
I've not worried about my slight mess-up: hopefully for a first attempt it will look OK
Right, process is claiming 30 minutes, then the upload
If all looks good, next is @DavidCarlisle
Next year: video :-)

@PauloCereda Not really, no. I had quite a lot to do yesterday!

@JosephWright: I'm also a Vimeo fan, maybe this info might be interesting: 
How many videos can I upload?

You can upload up to 5 videos at a time as long as they don't exceed your weekly upload quota.

Basic account users can upload 500 MB a week (with a max of 10 files per day). Plus users can upload 5 GB per week, and there is no per-day upload limit.

This quota resets weekly, and your personal reset day can be seen on the right side of the Upload Page, along with how much space you have remaining this week. Videos that you upload remain on the site, so you can upload 500 MB of videos this week, and another 500 MB next week, and they'll all be there for the wat…

@cmhughes Open access
I've got about half a dozen recordings to sort out. They will take a while, as I need to listen though to sort out the slides (which we did not record). Next year, I'm asking for a video camera and VGA input splitter :-)
I hope I can sort David's talk later this evening (I have to go out for a couple of hours)
