Hi!<br><br>Advantages of firewire approach:<br>1. Bus design. Internally, the firewire chip doesnt have to ask the CPU to copy data<br>to its port, it just does it, while USB devices use the CPU for this task. <br>2. On cheap laptops (and unfortunat others) the IRQ's between USB & something else<br>
collide. This means worse performance. (I'm aware that Firewire IRQ's can collide too,<br>but I've never seen that phenomena before.)<br>3. Firewire daisy chaining does still exist, at least for the Echo Audiofire devices that I have.<br>
4. I run a laptop (so PCI / PCI-E and a lot of other options are out. )<br>5. From my experiences, Firewire devices seem to be more geared towards professional use,<br>while USB targets the "pro-sumer" market. (No flame bait intended here..)<br>
<br>I like the Pure::Dyne, its always done well on my laptop. I've Dyne::Bolic before Pure::Dyne was<br>released, and I've been keeping a close eye on AV Linux too.. Between them I've kept my production<br>system installed (Pure Dyne), and a range of "testing" partitions with alternatives for Video / Blender work.<br>
<br>Installing Pure::Dyne is no problem, there's an GUI installer on the Desktop IIRC.<br>I'd run it live first, just to check it out to be honest. Not sure about RAID, never needed it.<br><br>Your question 2 has me confuzed I'm afraid, you're asking how its updated? The same<br>
as any other system... a packet manager. Or do you mean how does the LiveCD get updated?<br>I think new ISO's are generated every once in a while... not sure. Check out RemasterSys if your<br>hoping to update your Live system and keep it on a CD. (AV Linux is a debian based RemasterSys distro).<br>
<br>I'm not sure if Pure comes with development tools... It does come with PD, Processing, Arduino software<br>etc, but I dont think it has g++, gdb, svn or those installed. That said, its all a "sudo apt-get install <x>" away.<br>
<br>If you decide to try it, hope it goes well. Your mileage may vary ;-)<br>Cheers, -Harry<br><br><br><div class="gmail_quote">On Sat, Jul 10, 2010 at 8:20 PM, Jonathan E. Brickman <span dir="ltr"><<a href="mailto:jeb@joshuacorps.org">jeb@joshuacorps.org</a>></span> wrote:<br>

It has been extremely well-behaved.<br>
<br>
In your opinion, what is the advantage of the Firewire approach?<br>
Cabling? Replaceability? Ease of multitrack functionality? The<br>
Firewire daisychain capability (does it still exist)?<br>
<br>
I just checked out the Pure::Dyne web site. Very promising and<br>
up-to-date, not like I last saw it a while back. Questions:<br>
<br>
1. Does it install onto hard drive reasonably easily? I noticed that<br>
that page in the wiki isn't there yet, just a title/placeholder. Can it<br>
do RAID-1 without terrible pain?<br>
<br>
2. If it's designed explicitly for DVD/USB use (and it looks like it<br>
is), is that how it's updated? In other words, can I expect to just<br>
update my system device and it will use an existing older-version<br>
profile reliably? This would be a very good way to keep a production<br>
machine.<br>
<br>
3. Does it include thorough current compilation capabilities?<br>
