00:00
<Hixie>
apparently
00:00
<Hixie>
i think i'll wait for adam to write the i-d though
00:00
<annevk>
there will be an ID? ok
00:01
<annevk>
guess he can define authoring requirements and such then, neat-o
00:01
<Hixie>
i hope so
00:01
<Hixie>
gonna be pretty short, i expect
00:01
<annevk>
the header is already registered fwiw, but I guess doing it separately from both HTML5 and CORS is fine
00:01
<Hixie>
it's CORS now?
00:02
<annevk>
pretty much
00:02
<Hixie>
cool
00:02
<Hixie>
remind me to update xbl next year or so
00:02
<Hixie>
:-)
00:02
<annevk>
hehe
00:03
<annevk>
hopefully xbl has some implementor traction by then
00:03
<Hixie>
yeah
00:03
<Hixie>
i've heard louder rumblings than usual recently
00:03
<Hixie>
so we'll see
00:04
<Hixie>
i want people to implement type=date and type=color
00:04
<Hixie>
in multiple browsers
00:04
<Hixie>
that would get us a lot of traction i think
00:04
<annevk>
that'd be cool
00:04
<Hixie>
(from the average author)
00:04
<Hixie>
i mean, i'd love to blog about html5 and say why it's a great idea and all, but it'll sound hollow until we have something concrete that authors can use widely
00:24
<Lachy>
I found the videos that taught me about complex numbers http://www.dimensions-math.org/Dim_download2_E.htm (chapters 5 and 6)
01:32
olliej
is honestly not sure what to make of the latest whatwg mailing
01:33
olliej
has drafted multiple replies and decided they're all too far at the "what the hell are you talking about" end of the spectrum
01:40
<Lachy>
olliej, which mail are you talking about?
01:40
<olliej>
oh
01:40
<olliej>
web apps wg list
01:41
<Lachy>
ah, do you mean "[Web Workers API] Data synchronization"
01:41
<olliej>
yup
08:13
Hixie
collects interesting data for how to handle <a href="javascript:'...'" target=iframe> for various cases like same-origin, cross-origin, same-browsing-context, child browsing context, etc
09:27
<gsnedders>
Hixie: "Advanced maths"? Even in my sister's day (i.e., before yours), it was "further maths".
10:05
<annevk>
hmm, afaict most on* attributes start out as undefined in most browsers
10:19
<hendry>
annevk: why did you "dropped the RSS feed in favor of Atom. If someone can increase the acceptance of rel="feed" in user agents that would be much appreciated as it would save me thirty-three characters on several pages. No, I don’t have Google’s bandwidth bill, but readability counts.
10:19
<hendry>
16th January 2009
10:19
<hendry>
annevk: oh crap copy and paste :)
10:20
<hendry>
annevk: was thinking Atom is draconian right? so why use it
10:21
<annevk>
RSS is too
10:21
<annevk>
but no feed reader is so in practice it doesn't matter much
10:22
<hendry>
annevk: i noticed when i had an error in my atom feed, it wouldn't render in firefox
10:22
<hendry>
annevk: though an error in rss rendered
10:22
<hendry>
hence i stopped using atom
10:22
<annevk>
ok
10:22
<annevk>
my RSS feed sucks though, it's not full text
10:25
<annevk>
I mean sucked, it's gone now
10:25
<annevk>
to a nice place Ubuntu calls trash:///
10:25
<hendry>
urgh
10:25
<gsnedders>
hendry: Fx uses the same XML parser for both
10:26
<hendry>
gsnedders: i could be wrong, i didn't really investigate
10:26
<gsnedders>
So the same error should cause a fatal XML error in both
10:27
<gsnedders>
annevk: And SP supports @rel=ffed' :P
10:27
<gsnedders>
*feed
10:29
<Philip`>
hendry: Couldn't you have just fixed the error in your Atom feed? :-)
10:33
<hendry>
Philip`: i just switched to RSS and things started working. Hence I was thinking why Atom? :)
10:33
<annevk>
for a moment I thought http://hixie.ch/specs/hsf/hsf might of help when it is done, but it uses XHTML, go figure
10:33
<annevk>
might be of help* geez
10:33
<gsnedders>
It's what became hAtom
10:33
<gsnedders>
Last-Modified: Thu, 04 Sep 2003 12:48:48 GMT
10:34
<gsnedders>
However, that has even less support in normal feed readers than @rel='feed'.
10:34
<annevk>
no need to tell me things I already know :)
10:34
<gsnedders>
annevk: Then why link to that and not hATOM ?:P
10:34
<gsnedders>
*hAtom
10:35
<gsnedders>
Damned Anne trying to confuse me!
10:38
<annevk>
i'm not at fault, you're trying to apply logic to this situation
10:42
<gsnedders>
True.
14:23
<gsnedders>
jgraham: (It always will, because it does more. But the cost is greater than it need be at the moment.)
16:08
<Philip`>
I suggest calling them "cabalists"
16:09
<gsnedders>
An unauthorised calculator is defined as:
16:09
<gsnedders>
♦ a calculator with inadmissible facilities, eg a computer algebra system (CAS)
16:09
<gsnedders>
♦ a calculator which contains inadmissible data or text
16:09
<gsnedders>
♦ any form of hand-held computer, eg a personal digital assistant (PDA)
16:09
<gsnedders>
So that's what I need.
16:09
<Philip`>
You need an authorised calculator?
16:10
<gsnedders>
No, just one that isn't unauthorised :P
16:10
<Philip`>
Oh
16:10
<Philip`>
I typoed
16:10
<Philip`>
I meant:
16:10
<Philip`>
You need an unauthorised calculator?
16:11
<gsnedders>
No, I need one that is authorised :P
16:11
<Philip`>
So when you said "that's what I need", you meant the complete opposite?
16:11
<gsnedders>
Yeah.
16:11
<gsnedders>
Obviously.
16:11
<Philip`>
But I can't complain since I said "authorised" when I meant the complete opposite :-(
16:11
<hsivonen>
gsnedders: is diamond #2 something that you are allowed to address by letting a teacher reset your calculator?
16:12
<gsnedders>
diamond #2?
16:12
<hsivonen>
gsnedders: or do you need one that they can tell is authorized by looking at it
16:12
<gsnedders>
Oh, that sort of diamond.
16:12
<gsnedders>
I dunno.
16:14
<hsivonen>
gsnedders: if you need the latter, I suggest pushing as close to the limit as you can by getting a calculator that has an editable input buffer
16:15
<gsnedders>
Yeah, I already have such a calculator (just non-graphical).
16:15
<gsnedders>
Anyone have any opinion on the TI-84?
16:54
<annevk>
yay, more RDF e-mail :)
16:54
annevk
&heart; RDF e-mail
16:59
<Dashiva>
You should express that as RDF so that it can be reused
17:01
<gsnedders>
Also, I'd be able to add it to my knowledge-base about you.
17:01
<annevk>
two good reasons not to me
17:01
<annevk>
s/ me//
17:02
<annevk>
and a knowledge-base about me, wtf?
17:02
<annevk>
you guys are crazy
17:02
<gsnedders>
We stalk you, don't you know?
17:02
<annevk>
aah, that explains why my garbage bin moves at night
17:02
<gsnedders>
It's one of many great uses of RDF!
17:25
<annevk>
more xml:id fallout: http://blog.jclark.com/2009/01/relax-ng-and-xmlid.html
18:18
<Dashiva>
Oh, Shelley...
19:22
<hsivonen>
Shelley's mention of RSS 1.0 is interesting, because after flirting with RDF, the feed community knowingly moved away from RDF
19:23
<hsivonen>
also, Mozilla implemented RDF when it was a new and unproven thing and has since moved away from using RDF internally
19:42
<annevk>
per definition all the xmlns="" and xmlns:<foo>="" attributes are different in HTML and XML
19:42
<annevk>
apart from that, everything is equal I think
19:42
<annevk>
as far as RDFa goes
19:44
<Dashiva>
"SVG and MathML had valid use cases. Therefore RDFa must be added for no real reason."
19:44
<annevk>
Dashiva, you know, remarks like that is why I voted three times for you on lastweekinhtml5 :)
19:45
<annevk>
ooh, jgraham is close to BenMillard now
19:45
<Dashiva>
annevk: Plan "make anne confess", great success
19:46
<annevk>
Dashiva, :p
19:47
<Dashiva>
I'm confused with the top, though
19:47
<Dashiva>
Ben isn't very smeggy at all
19:48
<annevk>
http://zaa.ch/past/2009/1/17/the_future_of_the_web/
19:49
<hsivonen>
at least we've moved from the Vast Browser-Wing Conspiracy towards a Google Conspiracy
19:50
<Dashiva>
hsivonen: That ruins your mozilla example, though
19:50
<Dashiva>
Since they're obviously being pressured by their sugar daddy Google to avoid RDF
19:50
<annevk>
Plan "make people think it's a Google Conspiracy", great success
19:51
<annevk>
Dashiva, yeah, and Google was also involved in Atom! Bastards.
19:52
<hsivonen>
annevk: I thought they they hired Atom people afterwards
19:52
<Dashiva>
Cover operation
19:52
<annevk>
hsivonen, Blogger was one of the first to deploy Atom 0.3
19:52
<annevk>
Blogger was part of Google already, right?
19:52
<hsivonen>
oh
19:53
<gsnedders>
annevk: yeah
19:53
<BenMillard>
Dashiva, thanks. :) The poll still puts me at 10x more smeggy than you, though.
19:53
<gsnedders>
And I still have no votes.
19:54
<BenMillard>
annevk, plan "mark everything on Public-HTML as read unless includes me in the To or CC line", great success. :)
19:54
<Dashiva>
annevk: Going back to your link
19:54
<Dashiva>
"(...) any realization of a Semantic Web will depend on structured data."
19:55
<svl>
gsnedders: I see four votes for you under "all of the above"
19:55
<gsnedders>
svl: Smartass.
19:55
<svl>
^_^
19:55
<Dashiva>
So not only is RDF axiomatically going to happen, the semantic web is too
19:55
<gsnedders>
Hmmm…
19:55
<annevk>
Dashiva, great, guess we don't have to do anything then :)
19:55
<gsnedders>
$x = \frac{16}{b-1}$
19:56
<gsnedders>
$x$ and $b$ are natural numbers.
19:56
<annevk>
no math post-5PM
19:56
<gsnedders>
There is a sequence, x, x + 8, bx.
19:56
<Dashiva>
annevk: Fix the mathml bug
19:56
<gsnedders>
What possible values of x and b are there?
19:56
<gsnedders>
annevk: I have a maths exam on Monday, thus maths will appear after 17:00
19:56
<annevk>
Dashiva, what MathML bug?
19:57
<Dashiva>
The one where we only render the first part in a mfenced
19:57
<annevk>
gsnedders, they can appear after 17:00, but only if it's also after 5:00
19:57
<gsnedders>
annevk: It is currently after 5:00.
19:57
<annevk>
Dashiva, if by we you mean Opera, yeah, we should just do MathML natively
19:57
<annevk>
gsnedders, true, I meant the 5:00 that comes after 17:00 though
19:57
<Dashiva>
gsnedders: Multiply by b-1 and factorize?
19:57
<annevk>
gsnedders, i.e. tomorrow
19:58
<gsnedders>
annevk: Oh, I didn't realize.
19:58
<gsnedders>
:P
19:58
BenMillard
chuckles at time format humour, sadly.
19:59
<gsnedders>
x(b-1) = 16…
19:59
gsnedders
wonders how to factorize that
20:00
gsnedders
blatently sucks at maths
20:02
<Philip`>
gsnedders: I suggest finding the factors of 16
20:02
<Dashiva>
Try x = any divisor of 16 (including negative) and see if it works
20:02
<Philip`>
$ factor 16
20:02
<Philip`>
16: 2 2 2 2
20:03
<Philip`>
Oh, that's only prime factors, which isn't so useful
20:03
<gsnedders>
1, 2, 4, 8
20:03
<gsnedders>
It's not that hard to work them out :P
20:03
<Philip`>
and 16
20:04
<gsnedders>
and it should work for all.
20:04
<gsnedders>
according to the answers.
20:04
<Philip`>
Since b-1 divides 16, b-1 must be 1 or 2 or 8 or 16 and it's trivial to find x
20:04
<Philip`>
...or 4...
20:07
<hsivonen>
did Opera include some RDF APIs at some point? I can't find documentation.
20:08
<annevk>
hsivonen, I don't think so
20:08
<hsivonen>
oh. interesting
20:09
<annevk>
all we support is the RDF meaning RSS 1.0 ...
20:11
<hsivonen>
annevk: do you parse it into a graph?
20:14
<annevk>
no
20:25
<gsnedders>
Hmm, for all those (i.e., (x,b) = (1.17)…(16,2)) "calculate the sum of the first 10 terms". So, using $0.5*10(x+(10-1)8)$ I get the wrong answers
20:25
<gsnedders>
But s/x/2x/ gives the right answers.
20:25
<gsnedders>
(Assuming the given answsers are correct)
20:25
<gsnedders>
*answers
20:26
<gsnedders>
Why would it be 2x?
20:27
<Dashiva>
First ten in what order?
20:27
<Philip`>
First ten of what?
20:28
<gsnedders>
The arithmetic sequence x, x + 8, bx
20:28
<Philip`>
That's not a sequence, it's just three numbers
20:28
<gsnedders>
(for which we found possible values of x and b)
20:28
<gsnedders>
Sorry, that's the first three terms of the sequence
20:28
<gsnedders>
So the sequence should be, I think, x + (n-1)8
20:29
<Dashiva>
I don't think this qualifies as well-defined
20:29
<gsnedders>
Dashiva: That's normal in this textbook.
20:29
<gsnedders>
:(
20:29
<Dashiva>
You're holding out on us
20:30
<gsnedders>
Yet the only way this works for the final part of the question is 2x + (n-1)8
20:30
<gsnedders>
Which inevitably breaks what I asked above
20:30
<Dashiva>
Why don't you tell us the whole question :)
20:30
<gsnedders>
Dashiva: Because Im lazy? :)
20:30
<Philip`>
x + (n-1)8 doesn't look like it involves b at all
20:31
<jcranmer>
arithmetic sequences you can solve given only two terms
20:32
<jcranmer>
well, two terms and you know what number those are
20:33
<Philip`>
That's true but, I think, irrelevant :-p
20:34
<Philip`>
Oh, maybe not
20:34
<Philip`>
"The arithmetic sequence x, x + 8, bx" is only an arithmetic sequence if bx = x+16
20:34
<Philip`>
and the earlier condition on b and x means that's true
20:34
<gsnedders>
http://pastebin.ca/1311084
20:34
<gsnedders>
There's the full question.
20:35
<Dashiva>
... that's a very different question!
20:35
<gsnedders>
The bx part is completely irrelevant in the final part.
20:35
<Dashiva>
And Philip` answered it
20:35
<gsnedders>
Where?
20:35
gsnedders
is blind
20:36
<Dashiva>
Guess you're out of luck then :(
20:36
<gsnedders>
:P
20:36
<gsnedders>
The final part it gives answers 370–520.
20:36
<gsnedders>
I got 365–440.
20:38
<Philip`>
The first term in the sequence is x, the tenth term is x+8*9, so the mean is (x+x+8*9)/2 and the sum is 10*(x+x+8*9)/2
20:38
<Philip`>
which is 5x+36
20:38
<gsnedders>
If the sequence were $2x + (n - 1)8$ for the $n$th term, and not $x + (n-1)8$, I would get those answers
20:39
<Philip`>
Wait, I can't do arithmetic
20:39
<gsnedders>
Philip`: That disagrees with both me and the textbook
20:39
<Philip`>
It's 10x+360
20:39
<Philip`>
so the answers are 370, 520, etc
20:40
<gsnedders>
It should be $0.5n(x+(n-1)8)$
20:40
<gsnedders>
Oh wait.
20:40
<Philip`>
I think you're missing a +x in the middle
20:40
<gsnedders>
I can't read.
20:40
<gsnedders>
It should be 2x
20:41
gsnedders
can't read the textbook
20:42
jcranmer
sighs
20:42
<gsnedders>
Scary problem: I'm meant to know a large number of equations on Monday
20:42
<Philip`>
You shouldn't know the equations, you should just know how to derive them :-)
20:43
<hsivonen>
Philip`: deriving everything from axioms in a test takes time
20:43
<jcranmer>
hsivonen: that's how I survived AP Physics
20:43
<gsnedders>
Philip`: Yeah, I do that with the computing things (mainly we are meant to remember algorithms). But in maths, as hsivonen, it takes precious time.
20:43
<Philip`>
(e.g. I don't know the equation for summing arithmetic sequences, but I know it's the average of the first and last terms multiplied by the number of terms)
20:44
<Philip`>
hsivonen: You don't need to start from the axioms and produce a formal proof, so it's not quite that bad :-)
