Schema change release: Today at 17h UTC

We’re going to start our schema change release process today at 17h UTC.

We anticipate having a short downtime of a few minutes as we”ll need to restart our database server. As usual, we’re not certain when we will start the downtime, but we’ll keep people posted about our progress in IRC and on Twitter.

Once we’re done with the release we will post instructions on this blog on how to upgrade any replicated instances of MusicBrainz you might be running.

Stay tuned!

May 2017 Schema Change Release: May 15, 2017

We have picked our set of tickets and the date for our May 2017 schema change release: May, 15th 2017. This will be a fairly standard and minor schema change release — we’re only tackling 3 tickets that affect downstream users and no other infrastructure changes.

Take a look at our  list of tickets for this schema change release. There really are only two tickets that will affect most of our downstream users:

  • MBS-8393: “Extend dynamic attributes to all entities” Currently our works have the concept of additional attributes which allows the community to decide which sorts of new attributes to apply to a work. (e.g. catalog numbers, rhythmic structures, etc) This ticket will implement these attributes to all of our entities. Also, this ticket will not change any of the existing database tables, it will only add new tables.
  • MBS-5452: “Support multiple lyric language values for works” Currently only one language or the special case “multiple languages” may be used to identify the language used in lyrics. This ticket allows more than one language to be specified for lyrics of a work.

The following tickets are special cases — they will not really affect our downstream users who do not have edit data loaded into their system. We are only including this change at the schema change release time in order to bring some older replicated systems up to date. If you do not use the edit data, then please ignore these tickets.

  • MBS-9271: “Prevent usernames from being reused” This ticket does not change the schema, but for sake of minimizing downstream disruption, we’re going to carry out this ticket during the schema change.
  • MBS-9274: “Fix the edit_note_idx_post_time_edit index in older setups to handle NULL post_time” This ticket fixes an SQL index on an edit related table.
  • MBS-9273: “Fix the a_ins_edit_note function in older setups to not populate edit_note_recipient for own notes” This ticket also fixes an SQL index on an edit related table.

This is it — really minor this time around. If you have any questions, feel free to post them in the comments or on the tickets themselves.

 

We’ve hired another MusicBrainz developer!

I’m pleased to announce that Yvan Rivierre has joined the MusicBrainz development team! Yvan is not new to our community — he has been participating MusicBrainz development for some time and more recently has been attending our weekly community meeting. He’s submitted several pull requests to MusicBrainz already, and now he joins us as a full time developer.

Yvan’s nickname on all things MetaBrainz is now yvanzo, was formerly yvanz, in case you’re wondering what happened. Expect him to be around even more, helping bitmap to make improvements and changes to MusicBrainz. The MusicBrainz search infrastructure and hosting are no longer core tasks for the MusicBrainz team, leaving yvanzo and bitmap to focus solely on MusicBrainz. This brings us to a new level of dedication to our most important project and should allow us to tackle more issues faster focus new areas of improvement. (e.g. hopefully we can start making improvements in UX/UI this year!)

Welcome aboard Yvan!

MetaBrainz has been accepted to Summer of Code 2017!

I’m pleased to announce that MetaBrainz has been accepted into the Google Summer of Code program for 2017!

If you are an eligible university student who would like to participate in Summer of Code and get paid to hack on a MetaBrainz project over the summer, take a look at our ideas page for 2017. If this sounds interesting, take a look at our getting started page.

We kindly ask that you carefully read the ideas page and the getting started page before you contact us for help!

Thanks and good luck applying!

Welcome to the team Elizabeth!

I’m very happy to announce that we have a brand new Supporter Catalyst on our team. Elizabeth Bigger, AKA Quesito, joined our team at the beginning of the year and is now coming up to speed.

Her duties include making contact with any supporters who sign up on the MetaBrainz site and to sort out any questions they may have working with such a quirky organization like MetaBrainz. She’ll also be reaching out to established customers to make sure that they are on the right support level and that things are working smoothly for our supporters.

I anticipate her also helping out with other tasks such as putting on our annual summit and other events we may hold in our office in Barcelona.

Welcome on board, Elizabeth!

New MusicBrainz Virtual Machine released

We’ve finally released a new MusicBrainz virtual machine! This new version has become a lot more automated and is much easier to create and deploy. Hopefully we will be doing monthly releases of the VM from here on out.

lot of things have changed for this new release. If you have used the VM before, you MUST read the instructions again. Before filing a bug or asking us a question, please re-read the documentation first!

Ready to jump in? Read the instructions.

Google is awesome: How should we spend $5000?

The Google Open Source Programs office is amazing!

In the past few years Google has sponsored our summit where we gather a pile of MusicBrainzers into one room and talk shop (and a bit of play) for a whole weekend. But, due to extenuating circumstances and our move to NewHost, we opted for a much smaller and lower key developer gathering in Barcelona. As a result we didn’t spend much money and I opted to not pester Google to support our summit as they have in the years past.

Then yesterday the lovely Cat Allman from OSPO send us a PO for $5000 and a stern reminder to send an invoice soon. After explaining the situation to Cat, she still felt it was appropriate to collect the money and to “use the money as best serves the project.” 

Wow, thank you!

The question I have, for all of our readers, contributors, editors, hackers and advocates: How do you think we should spend $5000 to best serve MusicBrainz and its sister projects?

I’ll leave it wide open to everyone to chime in — feel free to put suggest anything reasonable and meaningful in the comments. Please do the skip the “send it to me!” type comments. 🙂

Finally, I want to thank Google for its continued support of our projects. Through its annual support of $40,000, Summer of Code, Code-In, the paid data license for its Knowledge Graph and the support of our summit, Google is the biggest supporter of the MetaBrainz Foundation. By far: Google has donated more than $366,000!

THANK YOU GOOGLE. Your support really helps us along!
