hiya

The most productive thing I did today was http://mustaqila.servehttp.com/temp/delivery.html

uuhhh. wtf url and real url?

xkcd -> questionable content. qc -> dino comics, dino comics -> xkcd

nice. :)

sprøtt!

they all collaborated in makign people go "wtf?"

submitted one of my musicbrainz gsoc proposals...

phatmonkey: Congrats!

it's for the javascript

if I have time I'll submit one for mb_server too, I feel I have a better chance with that because it fits my areas of expertise better

To make the JS work?

yuh basically

rewrite it

That would be nice.

It only "kinda" works.

oooh, thenext xkcd will be 404

:o

With WS::MB, how to compute DiscID?

use libdiscid

So, it's not in the MB library anymore?

pbryan: Den EFF är en grundande så pass beskyddar elektronisk rättigheterna av medborgarskap om Förenta Staternas. => That EFF is a founding about so protects electronic the rights of citizenship about the United States'.

Interesting ;-)

Well, I don't actually speak Swedish.

I was just trying to fit in.

pbryan: its a separate lib now

ruaok: In Perl?

C

Okay. Thanks.

I C whut U did thar.....

natta!

pbryan: It's OK, I don't expect Swedish to be the official language of MB before the next server upgrade. You'll have time to practice.

symphonick: :)

ruaok: Any suggestions for Perl?

write a binding?

Doh!

I was afraid you'd say that..

Write a Perl module?

yep

that calls libdiscid.

should be simple since there are only a handful of calls

canidae: ping!

ruaok: I'm a bit stuck with my proposal

thinking about the tool to automatically add releases

ok

not sure how to do it without using too much resources. perhaps I should so some trade-off to gain performance

why do you say that?

tell me why you think it will take too many resources

Ben Chobot is one of the guys who replied to my e-mail with the proposal. He wrote about a website he made that does what I want to do. He use a tool to generate a XML file containing title, artist, album, PUID etc. And then on the server side he tried to figure out which releases the songs belong to

he wrote that these operations are expensive. and I think perhaps they are too expensive. have not done much research yet, but he sent me a lengthy e-mail describing how he is doing it

yes, that should not be done server side.

we should provide a means to to say: add this MBID to my collection.

how that MBID for a release is gathered is up to the user. perhaps picard can help there.

I'm thinking it would have to be done either like he is doing it - or another way could be to just extract artist, album, song count, year and perhaps something more to match directly with releases. this would only be reliable if the user has properly tagged music

ah

makes it a lot simpler, doesn't it? :)

hmm so instead it would send lots of queries?

Why not just pull the mbid out of the files, then submit those to the server?

BrianFreud: yep. punt the mbid determination onto the client.

I have a python script someone (I forget the name, and he vanished from in here months ago) wrote for me; extracts the mbid and the time -

I then give that to FauxFaux's server, it gives me the release and track rowids, so I can do time dumps.

niklas: we should have it support adding more than 1 id in one call.

But the same ought to be possible to just pull all mbids and submit those to your server to handle

ahhh I think I see

is the PUID identical for e.g. each physical CD release?(each song on it)

it should be.

but that depends on the rip.

but puids sholdn't factor into your feature at all, should they?

danderson, that was the person: script is short: http://musicbrainz.pastebin.com/m11994103

unless you're attempting to keep track of which releases and which tracks the user has.

or for example if one song is released as a single and is also included in an album - and later perhaps even on a greatest hits CD... these three copies wont have the same PUID?

but I think the latter is not as key, imho

niklas: they should have the same puid.

theoretically, assuming there's no remastering / over-dynamic compression / etc

ruaok: hmm shouldnt it? I might have misunderstood PUID

if its the same track, it should have the same puid.

regardless of where it was released.

ok

think puid as a fuzzy hash

like a hash of the information about the song?

it's an accoustic fingerprint - yes... assuming the other release doesn't totally fuxor the file (stretch/slow the time 6+ second, overcompress, etc)

yep

aha ok

(and yes, we have one Brazilian Nirvana release where they put one track on at 2x speed :P)

ruaok: pong

canidae: read your mail.

haha

hmm but I still have to figure out which release songs belong to?

mbids...

niklas: not your job.

oh. I will read up on mbids. this is new to me

we have mbids for artist, releases and tracks.

that's it.

ah. but lets say a user has an album with 7 songs. how do you know the mbid of these 7 songs?

one puid can have several mbids?

one puid should only ever resolve to one track mbid.

and if you have an album with 7 songs, assume that the user will tag them with Picard.

picard embeds mbids (all three) into the mp3s.

if we provide a tool, like BrianFreud was saying, to read those ids and submit them to the server, we're done.

BrianFreud: do you have a few minutes to do some simple photoshop work?

true. sounds good

(would be extra bonus cool if it pulled puids too:P)

what would it do with those puids?

ruaok sure

can you please take the metaweb logo from http://metaweb.com and doctor it so its suitable for our customers page?

well, if it is scanning files to pull mbids from tags, not hard to pull the puids and just dump the pairs to MB, right?

Im confused though. I thought you wrote that a song that exist on several releases have one PUID. I will read up on this :)

yup.

PUID != MBID

thank you for the help. sorted things out

np

niklas: a puid is a fingerprint that should be the same for one audio recording, no matter where it was released

the mbid for a track identifies exatcly one track on a specific release

outsidecontext: ah. but songs have a puid and releases(albums, singles etc) has a mbid?

ohh

ruaok: http://metaweb.com/images/mwlogo_lofi.gif no workie?

shit, where did you find that?

no, the song (that is the song's audiodata) has a puid, and the song has a mbid

the source to their page

that's perfect. :)

:)

duh. :)

niklas: a mbid just identifies one entity, think of it as a database primary key

I see. thank you!

makes things so much easier

doesn't it?

BrianFreud: back to my current obsession with charlie chaplin and "smile" from the film "modern times" -- the soundtrack from the URL (soundtrackcollectors.com) is a 1971 release, confirmed by a music librarian at LAPL central library

which one?

it would appear that there was no release of the soundtrack contemporary of the film

there were 3 UA LPs there, iirc

not altogether surprising

they're all much later than the filem.

LAPL cited the soundtrack collectors site

lol

I would caution though... SC is a great resource, but frequently wrong and/or incomplete

I wouldn't entirely rule out there still having been a reel release - SC doesn't list any of those.
