Low Latency vs. Real Time Kernel
by Brian Monroe
I've been spending a lot of time on the #opensourcemusicians channel
talking to Ubuntu Studio users about their kernel and latency times they're
getting. Seems like most of them are using g a stock kernel with the
preemptive option enabled and they are getting great latency results
(2ms)while utilizing the @audio group on their user. I ended up compiling
my own low latency kernel and I haven't had any issues with it yet. If this
is what we are missing for the spin I'd be happy to maintain packaging for
the kernel. I know ccrma has been behind a few kernel releases.
I saw the instructions for adding the real time patch for a tick less
kernel and from what I can tell it wouldn't be hard to get that rolling as
well.
I'm not entirely sure what ccrma does differently with their kernels
compared to other Linux users, and I'm still a bit of a noob so I could be
off base with this, but I would reason that we should be able to just
utilize the same settings to archive similar performance enhancements.
I thought I read that ccrma uses a unique scheduler, but if we could get a
2ms latency time without it, the point may be moot.

Liner notes
by Brendan Jones
A friend of mine, awesome music producer
(https://soundcloud.com/omegachildproductions) had a hardware failure
and decided to try Linux.
He is very much in the Mac world. Logic is is usual modus operandi. I
found myself recommending kxstudio. A bit sad really considering we are
maintaining the Jam spin.
How can we make this better? I would have loved to recommend the jam
spin. I'm starting to think perhaps I should take this outside of
Fedora, or maybe join forces with CCRMA, and/or start a remix. I love
the ideals of Fedora though.
Anyway

now February 3rd, 2014 (23:59 HAST)
So, if you were considering to submit a paper but couldn't make up your
mind yet, here is your chance to become active! Never forget that this
conference lives through the people participating in it.
February 3rd is the new deadline for all submission types: papers,
music, installations, workshop proposals.
Check out the link below for more info:
http://lac.linuxaudio.org/2014/participation
Please spread this information to anyone who might be interested.
If you have any questions, drop us a line at lac(a)linuxaudio.org
We are looking forward to seeing you in Karlsruhe in May!
Thanks,

Fedora 21 and beyond
by Brendan Jones
Hey all,
Where to next? (ha ha Fedora next - we will see)
A few points:
- we have had the same wallpaper for 3 spins now (yes I created it and
it is awesome but could be better - should change with every release)
- there is a legal issue with the icons we are using - there is a bug
raised but not actioned. We really need the offending icons removed or
choose a new set. Maintainer is AWOL
- we still haven't solved the problem of seamlessly integrating pulse
and jack
I'm starting to think that there is little point having a spin at all.
My original idea was that having the spin would encourage more users to
use Fedora and as a result create some kind of community (and hopefully
attract more upstream developers).
This hasn't happened. I'm too busy to blog, promote, berate the goodness
of the Jam etc. Maybe someone else is. Maybe we are not promoting
ourselves enough? I don't know. Maybe we are being lazy.
In any case, I will not be taking on any more packages, unless
explicitly asked by someone who actually gives a damn.
