wow, just went through the Picard 2.4 release

the improvement are very impressive!

kudos to the Picard dev team!

👍

@rdswift: amazing work on the docs!

I can't imagine how much effort that took!

and the performance improvements are crazy as well!

Thanks. Mostly I just copied from others and organized it. It needed to be done.

Yeah, the performance improvements are awesome.

!m rdswift

You're doing good work, rdswift!

!m zas, phw

You're doing good work, zas, phw!

I'm not sure if Gabriel is on irc, haven't been introduced to him yet :)

but

!m Gabriel :)

You're doing good work, Gabriel :)!

VERY good work. It was quite a learning experience for me just watching the way he profiled everything to find the areas to focus on.

yup, very methodical!

are there plans on moving https://github.com/rdswift/picard-docs to metabrainz GH org?

if it's not already an official meb project it should be :)

nice!

Now that it's (mostly) out of development mode and into maintenance mode.

Still need to iron out a few details like serving different versions and translation to other languages.

Mr_Monkey: can you help us with a tagger icon as a dashboard icon for the app?

Hi all. I'm creating a new vm with the instructions from https://github.com/metabrainz/musicbrainz-docker. When I get to creating the indexes it gets so far then I get ""server closed the connection unexpectedly". This has happened twice now. What's going on?

hi nelgin: which server is closing the connection? how much of CPUs/RAM do you have? how long it takes to (fail to) create indexes?

I'm not sure which server. I'm on the console so can only scroll back so far. I get Failed to import record. psycopg2.OperationalError) server closed the connection unexpectedly. This probably means the server terminated abnormally before or while processing the request. It then goes on to give a traceback for sir/indexing.py It fails after 182 minutes and 3 seconds. I have allocated 8GB

to the VM of which 4G was given to postgres via the tuning parameter.

I might be able to give 2gb more to the vm for reindexing but that'd leave the pc short, so it's be a temp measure.

it's usual to last a long time but the error is not

I'll ssh into the box and rerun the index so I can scroll back further

Ok, I'll rerun the indexing and let you know if I have more information, it'll probably be tomorrow since it's midnight here and I need sleep.

Ok, good night!

Morning!

Morning

helloo

hi, could someone on Windows 7 test if Picard 2.4 crashes for them and whether the fixed builds at https://community.metabrainz.org/t/picard-2-4-r... work?

Morning!

_lucifer there...?

SomalRudra: Shoot! What do you need?

ishaanshah: hey

Looking at the sections pr

it's nice that now it's technically possible to link to specific parts of the page

But realistically, how will a user know how to link a section

Should we add a copy button or something to the graphs?

You mean something like jump to a section?

i mean, i want to share my artist graph with a friend.

how will i know how to link that section specifically

A share button

The one with three dots

Upper right corner of graphs section

yep. makes sense to me

Ok ok

Will make a ticket and PR after the primary work

ishaanshah already has a PR, i think we can just do it in that one.

Oh great

Hi!

I was working on the backend for sitewide stats rn

It occurred to me that we have huge messages for each time range

So should I limit it to top ten per time range

or work on paginating over RMQ

I'm happy with limiting

But we should try a higher number, maybe the top 1000?

Yeah sure

Or would that be too much?

No that wont be the issue

I'll let you leave that configurable and we can play around with it.

But limits sound good to me.

it's just that we are only gonna show the top 10

Yeah, but we can still expose more data over the API

Yep, that makes sense

About the 3 dots thing

I would first like to get on with the backend.

it has been lagging a bit

I will get it done by the weekend

Sure, no rus

Rush

white_shadow: yes

Moooin!

How is that first PR coming, shivam-kapila ?

yvanzo: finally got a bit of time to review the post

Changed a couple things, seems good to publish IMO

_lucifer are we using ndk in the app?

white_shadow: yes but not directly

what for?

the chromaprint algorithm is called from a java wrapper which is written using ndk

but the wrapper is not inside the app itself rather added as a dependency

secondly for the taglib library to read metadata

again it is added as a depenedency

so in the app we do not directly use ndk but depend on two libraries that use ndk and expose java/kotlin apis for us

ok but what we had to achieve by using chromaprint algorithm?

to obtain the fingerprint of the audio track and try to obtain a match

you mean determining similar audio tracks?

Basically, chromaprint algorithm can generate an almost unique fingerprint for the audio file. If these audio files are already tagged with musicbrainz identifiers, the fingerprint can be submitted to acoust id database. Now, suppose someone else runs the algorithm on the same audio which does not have any metadata. Chromaprint will generate an almost equal fingerprint for it. We then query the acoust id database to check if this

fingerprint is already present. If yes, then we ask for the data they have related to it.

but you said we don't have the audio files of any song? Am i missing something here?

To be complete the rest of the workflow is as follows, AcoustID returns a small subset of the data we require. Then, we take the musicbrainz identifiers in this data and send to the musicbrainz servers to get the complete data available.

yes, we do not have any audio files white_shadow

but the users do. the users run chromaprint on their audio files

oh ok

the users submit the fingerprints

ruaok: With bumps like this

:p

white_shadow: see https://acoustid.org/stats

there is a large number of fingerprints already available

we just have to find a match if it exists

ok and what kind of metadata we look for?

all metadata

for instance, artist, genre, title so on
