Plus, with ALSA native in the kernel, i figure i've got a better chance with USB and stuff like that. cliffw > > /Robert > >

If we (the open source movement) let our "enemies" (closed-source businesses) make us behave like them, we have lost. A more creative approach would be to make a good OSX emulator (inverse Darwin) which lets those people run their killer apps under Linux. And by the way, isn't someone who uses and contributes to open-source apps under OSX/Solaris/etc still a part of the open source movement?

There will be an OSX driver for the Creamware platform. Reverse engieneering will be more realistic then, won't it? Blaze1st

Re: [linux-audio-dev] New form of GPL licence that protects Linux from proprietary world [was: New powermacs?]

Check it out (the results of a recent effort to port the Gentoo package system (portage - the backbone of Gentoo) to OS X: http://metapkg.org and on the Gentoo homepage (gentoo.org) Gentoo/MacOS X announced... thank you python!

OS X does look nice, and the few OS X audio apps i demo'd are solid. And, dual-booting w/Debian unstable was dead easy to do, i have OSS audio working jest fine with the built-in set, and i'm hoping to do ALSA via USB audio soon, which will be kewl. I like the hardware platform. The display is noticeably better than most Intel laptops, certainly better than the used ones i was comparing to. The Firewire Just Worked, right from the Debian install kernel. I've been using it with a IDE -> firewire disk carrier. The unit is solid. The built-in audio is okay, my model has no real inputs (built-in mic) - you would definately be using USB or firewire for Real Work. Using Open Firmware at boot instead of BIOS is sweet. With Linux, performance is fine, even with the 500mhz chip. The OS X on the other hand, is noticeably slooower than Linux (2.4.21 + 2.5.72 kernels ), especially at reboot. And the Mac world is insanely closed, it actually surprized _me how little choice you have with OS X - near as i can figure, you buy most everything from Apple, pay a bunch more money than a comparable M$ product, or suffer. And since they are _not a huge monopoly, they seem to have little shame about being closed - i was very amused by the way they attempt to corral the first-time user into signing up for .Mac (Apple's version of MSN) during the OS X install, iTunes also. The main thing-that-makes-me-nutbar is the keyboard layout. That's fixable with X, and you can set up keymappings with sysctl for some Mac-specific things. Main installation pain is the Mac version of fdisk, which is....terse. So in conclusion, i'd say the iBook + external converter (USB/fire) would make a fine Linux audio laptop. Get a decent sized disk, and you can dual-boot with OS X, and that will motivate you to run Linux again. :) cliffw (PS - http://www.penguinppc.org - is a good start point for Mac links) > Ivica Ico Bukvic, composer & multimedia sculptor > http://meowing.ccm.uc.edu/~ico > >

> "Ivica Bukvic" <ico(a)fuse.net> writes: > > Anyone care to comment or (please) dissuade me from potentially > making a costly mistake? ;-) I don't think it needs to be either/or -- I run sfront under Linux at work doing real-time things, and I run sfront at home using OS X doing real-time things, and both more or less work OK. Personally, I think the biggest issues are the different approaches OS X and Linux takes on real-time scheduling (constraint scheduling for OS X, SCHED_FIFO and friends for Linux), and on the need and methods for keeping the application in RAM to avoid swapping (the sfront OS X port took at lot of work to get this right, and in some ways sfront has a simple memory usage pattern ...). I think Linux may have something to learn from OS X on the former issue, and OS X may have something to learn from Linux on the latter issue -- at the moment at least, the "lazy swap-in" in OS X, even when the machine has hundreds of MBytes sitting unused, forces the application to do its own implicit memory management to avoid artifacts during start up. ------------------------------------------------------------------------- John Lazzaro -- Research Specialist -- CS Division -- EECS -- UC Berkeley lazzaro [at] cs [dot] berkeley [dot] edu www.cs.berkeley.edu/~lazzaro -------------------------------------------------------------------------
