Is this 'normal'? I have noticed that systemd takes quite a long time to build, but I have never spent any effort looking into exactly why.

[gentoo-user] cdda2wav slightly missing start/end of tracks on 1 CD set
I think I had a (self-inflicted) problem sending this message the first time. Here's hoping it works this time. Apologies for the dupe. This is a problem on only one 2-CD set (I hope). It's probably screwed up metadata... * track audio_01.wav has a song that ends, a bit of silence, and I can hear the first couple of bars of the song from audio_2.wav * track audio_02.wav is missing the first couple of bars. The song ends, followed by a bit of silence and the first couple of bars of the song from audio_3.wav * track audio_03.wav is missing the first couple of bars. RINSE/LATHER/REPEAT Question... is there a way to manually override the start-end times of the tracks within cdda2wav or any other ripping app? -- Walter Dnes I don't run "desktop environments"; I run useful applications

It's a very old format (predecessor of the dvd with a much lower resolution as far as I know). I have never seen one. Regarding the CDs, try to build mplayer with USE="cdparanoia". If you have a Blu-ray drive you probably want to build it with USE="bluray", too. And for some convenience you also may want to add USE="cddb".

Was hoping I wouldn't have to reinstall the whole OS... You have a 64 bit kernel, this is true, but a 32 bit userland. I don't know how Go does these things but apps don't usually talk to the kernel directly, they talk to libc. Which in your case is ... 32 bit Reinstall. Not necessary. It builds successfully with the command: linux32 emerge go Without the linux32 pre-command, the go build system detects the system as "linux/amd64". However, when adding it the system is identified as "linux/386". (But beware that it will probably cause issues when you update in future) I've been running a system with 64 bit kernel and 32 bit userspace for quite a few years and its only the 4th issue I've hit, so while its generally not supported, it still works mostly. For reference, the other issues I've hit are: - kernel ABI incompatibility with autofs (fixed in a later kernel) - virtualbox kernel modules needed to be built 64 bit - steam has issues detecting system & tries to launch 64 bit binaries (I'll try the linux32 trick with that later too) I'd never had more than passing interest in go, but tonight I've started working through the tutorial & I think I'll keep playing with it for a bit.

Granted they are going to > mostly apply to multi-threaded application codes. Your being over-optimistic. It seems to me all they're hoping for is to define a standardized and portable high-level interface for programming accelerators. The ones that will benefit the most is the same applications that can benefit from lower level technologies like CUDA. Scientific/number crunching applications, some kinds of clustering, etc. With no synchronization most existing multithreaded designs cannot benefit from it. And obviously code running on the accelerator cannot branch into the CPU, so no system or library calls. That leaves only purely number crunching loops. There's little of that on desktop and few of them can be fully optimized for parallelization. And to be worth the overhead of offloading the CPU needs to be maxed out. That leaves only the few applications I mentioned before. I'm looking at Intel MICs[1] and those look a lot more promising though still of limited use for desktops. It uses OpenMP so it has a lot less restrictions than OpenACC (a few ebuilds in the tree can already benefit from it with minor patches) and you can even offload whole proccesses. You can even ssh to the MIC since it runs Linux. It's not for the average desktop but they're not too expensive either. It may be worth it for high-end gentoo workstation (you can offload compile jobs with distcc) and I got a project on the backburner that can benefit from it. Do you know of any plans to enable offloading on the gentoo toolchain? I was able to build the offloading compiler using crossdev with a few hacks and wrote an ebuild for Intel's simulator[2]. I will work on enabling the host compiler tomorrow and may open a feature request and post patches once I get it working. The changes needed to enable it on the host are pretty trivial.
