Thread: Call for Google Summer of Code mentors, admins

Folks,

Once again, Google is holding Summer of Code.  We need to assess whether
we want to participate this year.

Questions:

- Who wants to mentor for GSOC?

- Who can admin for GSOC?  Thom?

- Please suggest project ideas for GSOC

- Students seeing this -- please speak up if you have projects you plan
to submit.

I don't mind being an admin again.

Will think on this.
Thanks,

I forgot to mark all.

I could be a co mentor, helping in overall coordination and supporting all the students in getting familiar with the
projectand community etc.

Take a look at the Project Ideas page from last year, and the project
TODO list. See http://www.postgresql.org/developer/summerofcode/#ideas.

One approach is to pick a research paper on some algorithm or technique
that's applicable to databases, and then implement that in PostgreSQL.

- Heikki

Can't we have something related to machine learning? I was thinking of extending a technique where we can fill in some
missingvalues in a data set for the user if he wants us to using some standard ml algorithms.

My suggestion is to rewrite (add) pg_dump and pg_restore utilities as
libraries (.so, .dll & .dylib). For me as a developer it will be a cool
feature. And I can be a mentor for this project of course!

Take a look at MADLib.  My suggestion would be extending the MADlib
functions; there's plenty of unimplemented ML algrothims which could be
added to it.

Sign me up on that list. Depending on projects, of course.

We'd need Peter to be the student for that one :)
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=682938

I can certainly mentor some packaging/QA/web frontend project(s) in
the apt.postgresql.org area.

As a mentor or as a student?

I don't think that's a good GSoC project. There's no consensus on what
to do, if anything, so 95% of the work is going to arguing over what we
want, and 5% coding. I'd suggest finding something more well-defined.

I went through the MADLib library and came up with the following two
ideas which I feel could be potential GSoC 2013 projects:

1) MADlib currently has K-means clustering implemented.I would suggest
implementing the K-medoids clustering as it has better performance as
compared to K-means clustering.We could use k-means clustering code
base as the starting point for our implementation.

2) A more complex project would be to implement backpropogation
algorithm for much better classification. This would require
implementing some parts of neural network algorithms as well.

Again, I am willing to mentor either of the two projects if they are taken.

Regards,

Atri

Can you gather together all of the projects suggested on this thread and
use them to create updated text for the GSOC page?  If you don't have
web repo access, I can create a patch, but if you can do the text, that
would be a big help.

Okay, I've pushed some changes to the repo for 2013 GSoC, and purged
the varnish cache so that it's visible immediately:
http://www.postgresql.org/developer/summerofcode/

I've also created a new GSoC 2013 wiki page with mentor volunteers and
project ideas submitted so far:

If anyone else has more projects ideas to suggest, please do share.
Students, please feel free to review the PostgreSQL Todo list for
inspiration: http://wiki.postgresql.org/wiki/Todo  Of course ensure
you don't choose anything too ambitious or trivial.

Okay, here's a random idea (which could be infeasible and/or
undesirable).  How about a way to internally schedule tasks using a
background worker process (introduced in 9.2) to wake on each tick and
run tasks?

So:

CREATE EXTENSION pg_scheduler;
--
schedule_task(task_command, task_priority, task_start, repeat_interval);

SELECT schedule_task('REINDEX my_table', 1, '2012-03-20
00:10:00'::timestamp, '1 week'::interval);

SELECT list_tasks();

-[ RECORD 1 ]---+-----------------------
task_id         | 1
task_command    | REINDEX my_table
task_priority   | 1
task_start      | 2012-03-20 00:10:00-04
repeat_interval | 7 days
owner           | postgres

SELECT delete_task(1);

Tasks would be run in sequence if they share the same scheduled time
ordered by priority descending, beyond which it would be
non-deterministic.  Or perhaps additional worker processes to fire
commands in parallel if necessary.

Disclaimer: I haven't really thought this through.

--
Thom

It does sound nice,something like cron?

We can use a scheduling algorithm, and can define a pool of tasks as well as a time constraint for the amount of time
whichcan be used for running the tasks.Then, a scheduling algorithm can pick tasks from the pool based on priorities
andthe time duration of a task.I can see a dynamic programming solution to this problem.

I think mcron already implements it all and is made to be embedded into
a larger program.

As long as your larger program is gpl. Not even lgpl on that one. I'd think that's a killer for that idea...

Oh, are we now talking about including a scheduler in core or contrib?

My understanding was that the background worker infrastructure had been
made in parts so that we don't even have to talk about a scheduler specs
and implementation details on -hackers, where the usual answer is that
we already have a system's scheduler anyways.

Here's some evidence for my last statement: custom background worker
processes are actually being introduced as part of 9.3, not available
in 9.2.  I don't think that changes things much though.

I wonder if we can add the domain, something like:

SELECT * FROM DOMAINS mydom;

Returns

{"a", "b", "c", "d"}

Hi,

I've been asked by a local student to be his mentor in GSoC. He is
interested in working on parallelizing hash join/aggregation.

So I'd like to volunteer to be a mentor for this project (if it gets
accepted).

I've asked him to post his project proposal on pgsql-students.

kind regards
Tomas
