Re: [SLUG] 64-bit Karmic Koala or not?
I'm going to get a new desktop at work and was wondering whether it's worth moving to 64-bit. I confess that I still dual boot 32-bit for one legacy application: Vuescan. But with enough tinkering with ia32-lib or VirtualBox, I bet I could get it to work. It used to work on 64-bit Intrepid. Other than that, I've been running a 64-bit desktop happily for years. This seems rather pointless when you can install a chroot 32bit system and run 32bits apps in it, or set up the ia32-libs see http://alioth.debian.org/docman/view.php/30192/21/debian-amd64-howto.html#id292205 http://ornellas.apanela.com/dokuwiki/pub:multiarch im sure ubuntu process would be similar if not identical Dean -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

on x86_64 is that a python issue or a variable size issue ? -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] MythTV hardware advice sought
Well now if this isn't relevant to my interests. I am in the process of building a new mythbox (the old one is getting on, p3 1ghz with 768mb of ram) too, and have managed to get the missus to approve ~1700. I want to use it for a few Virtual servers as well, probably run KVM. Most of this is from MSY and static ice searches though, plus I already have 650w vantec power supply not doing anything. Hopefully it inspires someone, but I am also hoping for a little bit of critique, especially from Jeff who I know uses his media centre for virtual machines as well.

The later: pointers are necessarily 64-bit rather than 32-bit when working with the longer word ISA. Naive software that simply uses the native word size of the machine can also waste memory, since it now allocates 8-byte rather than 4-byte integers. That tends to be more an issue with worse-is-better languages like Perl, Python and Ruby, which don't abstract the platform numeric model at all, because they export the larger words. C is hardly immune, of course... On the other hand, you *also* get a much larger register file, an improve ISA and the ability to assume a much more modern baseline system, so the performance difference for most use is about zero with AMD64 vs i386.

Re: [SLUG] MythTV hardware advice sought
Looks nice The I7 (and accompanying HW) might be a bit overkill for the task at hand. I'd think about dropping that down and upping the video card so you can do advanced 2x hw deinterlacing of 1080i stuff. That or put the money in your pocket ;- Only think I have noticed though is I was running KVM on 9.04 without any problems but now in 9.10 (upgrade) on my mythbox, guests are limited to ~80kbyte/sec xfer rates. Kinda sucked when it means my already crappy internet connection is limited by it. Taking stuff off the host I could pull it in at 45 mbyte/sec (gig-e) and I seem to recall running ~12mbyte/sec before the update from VM's. Anybody else noticed issues with KVM and network performance under 9.10? Morgan Storey wrote: Well now if this isn't relevant to my interests.
