Re: [Fedora-music-list] music spin development. I am ready to test/help with the audio spin.

[William Blackburn]

hello everyone,

I apologize for my ramblings this morning about the decision on whether or not to use the real time pre-emption patch.   If there is anything I can do to help move the spin forward, just let me know.  I am more than willing to help.  I think one important aspect may be to put the new version of rakarrack on the spin because the version in the repos is a bit outdated and that particular package is moving very fast.  There are instructions on how to build the package on the rakarrack website but I am not experienced enough to know how to incorporate that into the spin.  Maybe I can talk to one of the devs and ask him his thoughts on the idea.  
That's all I have for now.    Until next time, ciao!

> I would like to second the notion that a real time kernel would be the best option for this distro.  I hate to be a pessimist, but I don't see the point of making a music spin if it is going to have the same kernel as the the standard fedora distro.  Anyone can add packages, but a working rt kernel is special.  Also, if the real time kernel gets added, I think it may receive more attention and maybe get some nice improvements.  If we have to call it a remix and not spin, that is not important to me.  What is important is how useful it is to musicians and musicians do not like latency.  I understand that the kernel patch can be installed quite easily and this is just my opinion.  Please feel free to object to me or to correct me.  :)

We want to hear all your funny, exciting and crazy Hotmail stories. Tell us now

music spin development. I am ready to test/help with the audio spin.

[Christopher Antila]

It's good to see more people getting involved!

We have lots of (relatively!) easy ideas, like including recent versions
of software.  Why don't we start on the difficult stuff by deciding on a
target audience?  This will help us to determine whether we want to
bother with a real-time-enabled kernel, exactly what software to
include, and other things.

Here's my proposed target audience, derived mostly from the FP User base
page[1], and the other pages in the "About Fedora" series:

Typical User:
A home user who wants to accomplish all sorts of everyday tasks with one
distribution, including high-quality audio creation tasks, home office
tasks, and communications tasks like IM, IRC, and email.  This person
knows enough that, if given instructions, they would be able to make all
of the modifications and installations for themselves - but now they
don't have to.  The user is already reasonably experienced with using
most of the software included with the Audio Creation version of Fedora.

There are two important things here to consider: the user is not a
novice computer-user, because this doesn't follow Fedora's goals; the
user is making a conscious choice to go with an Audio Creation version,
rather than the mainstream version, so it should be considerably
different from the mainstream version.  It shouldn't be the kind of
thing that could be done just as well by spending an hour with
PackageKit - it should be significantly different, and sufficient
without further modification for all audio creation purposes.

This is my opinion.  I hope somebody disagrees, so we can evaluate
different options!

Christopher.

If there is anything I can do to help move the spin forward, just let me know.  I am more than willing to help.  I think one important aspect may be to put the new version of rakarrack on the spin because the version in the repos is a bit outdated and that particular package is moving very fast.  There are instructions on how to build the package on the rakarrack website but I am not experienced enough to know how to incorporate that into the spin.  Maybe I can talk to one of the devs and ask him his thoughts on the idea.

Please see:
http://fedoraproject.org/wiki/AudioCreationSpinDevelopment

- put yourself in the list of people
- add any tasks you think we need to do to make the spin a reality
- add yourself to any of the tasks
- add / edit comment on the list of packages that should make it into
the spin
- test and leave comments for any audio package announced on this list
> I think one important aspect may be to put the new version of rakarrack

AFAICT the current release of 0.5.8 is what is now in Fedora 12,13 and
has been in development for a while.

On a side note: general email list etiquette applies here as well:
- don't top post
- only quote / include text that you are actually replying to
(especially not whole list archives of 100kB !). Find the point you want
to address and quote just that part.

You might like to set yourself to remove individual, rather than archive
mail. This helps everyone else on the list since many people use
threaded email readers, that keep all messages that are "reply to" in
the same thread.

Cheers, David Timms.

remove => receive !

Renamed sping page to be wiki-friendly (was music spin development. I am ready to test/help with the audio spin.)

I just renamed that page, which sets up an automatic redirect.

https://fedoraproject.org/wiki/Audio_creation_spin_development

(Sorry for the after notice, but it shouldn't affect your usage, and
this is just part of the wiki gardening service.)

The reasoning for descriptive names with spaces is explained here:

https://fedoraproject.org/wiki/NAMING

The most relevant reason here is that a search for "audio" via the
MediaWiki search would not have turned up the page under the title
search.
