Mar 22 08:08:57 <VoodooZ_work> hey
Mar 22 08:09:20 <VoodooZ_work> I quickly realised how "slow" the slug is last night when I ran my CV test on it.
Mar 22 08:09:48 <VoodooZ_work> What took only ~170ms on my P3-900  took a whole 1.3 seconds on the slug! 
Mar 22 08:10:18 <VoodooZ_work> I had to optimize radically but I got it under 0.2seconds by downsampling the image size and other stuff.
Mar 22 08:10:37 <VoodooZ_work> I guess the memory speed on the slug is a killer when scanning every pixel.
Mar 22 08:20:51 <VoodooZ_work> NOw if could only overclock the slug! :)
Mar 22 08:22:21 <ka6sox-office> VoodooZ_work, sri...Intel is very much against that....they even mention it in their literature.
Mar 22 08:24:06 <VoodooZ_work> screw intel! :)
Mar 22 08:24:16 <ka6sox-office> ya
Mar 22 08:24:19 <VoodooZ_work> I've been o/c intel/AMD processors for years./
Mar 22 08:24:28 <VoodooZ_work> btw, AMD rules!
Mar 22 08:24:34 <ka6sox-office> on this one they have steps to prevent that.
Mar 22 08:24:44 <VoodooZ_work> yeah, unfortunately.
Mar 22 08:24:56 <VoodooZ_work> you mean on the slug they do?
Mar 22 08:24:56 <ka6sox-office> interesting that its supposed to be 33.333 mhz and the crystal is 33.000mhz
Mar 22 08:25:11 <ka6sox-office> no...in the IXP4XX
Mar 22 08:25:12 <VoodooZ_work> Is the memory bus running at 33?
Mar 22 08:25:23 <ka6sox-office> no..133mhz
Mar 22 08:25:25 <VoodooZ_work> (that's what I mean)
Mar 22 08:25:29 <VoodooZ_work> ah
Mar 22 08:25:50 <ka6sox-office> theoretically...I'm going to look at that sometime.
Mar 22 08:25:59 <ka6sox-office> because of the lackluster performance
Mar 22 08:26:00 <VoodooZ_work> My computer vision code runs awfully slow though so there might be a limitation or architectural diff
Mar 22 08:26:18 <VoodooZ_work> Then again, I shouldn't be asking so much of a small ARM processor
Mar 22 08:26:47 <VoodooZ_work> I just thought it would be cool to do vision on my robot.
Mar 22 08:26:55 <ka6sox-office> either that or get a 533mhz one!
Mar 22 08:27:46 <VoodooZ_work> yeah. Later on I guess.
Mar 22 08:28:00 <VoodooZ_work> I want to use the slug after spending so much time getting it to work.
Mar 22 08:28:15 <ka6sox-office> exactly
Mar 22 08:28:28 <ka6sox-office> dualing Slugs
Mar 22 08:28:50 <VoodooZ_work> Maybe I'll get a gumstix next year or that nice SODIMM based 533Mhz one I saw recently with h/w i2c, lcd controller, audio...
Mar 22 08:28:53 <ka6sox-office> one for sensor processing and one for everything else.
Mar 22 08:29:02 <VoodooZ_work> ummm. could do that.
Mar 22 08:29:15 <VoodooZ_work> THe problem is the slug is not exactly power efficient.
Mar 22 08:29:21 <VoodooZ_work> (and not designed for that anyways)
Mar 22 08:29:28 <ka6sox-office> 1.5w is pretty efficient.
Mar 22 08:29:48 <VoodooZ_work> The processor perhaps but the rest of the board.
Mar 22 08:29:58 <ka6sox-office> (unless you are on an autonomous robot.
Mar 22 08:30:06 <VoodooZ_work> It's not meant to be portable anyways..
Mar 22 08:34:15 <VoodooZ_work> yeah, it will never be quite efficient enough for robotics. 
Mar 22 08:34:25 <VoodooZ_work> At least not until the damn batteries get better.
Mar 22 08:37:07 <ka6sox-office> yep
Mar 22 08:37:28 <ka6sox-office> back into the wood work here.
Mar 22 08:44:14 <VoodooZ_work> actually, I was wondering if it was possible to give my vision process a boost by insreasing it's process priority or something?
Mar 22 08:44:35 <VoodooZ_work> Would CONFIG_PREEMPT also help here?
Mar 22 12:51:21 <perlguru> .

Mar 22 18:09:55 <novacane_22> Does anybody know what the default root password is for openslug?
Mar 22 18:12:59 <ByronT> blank
Mar 22 18:13:32 <[g2]> ByronT, I believe that novacane_22 can't ssh into root with a blank pw right now
Mar 22 18:13:42 <[g2]> that's just a guess
Mar 22 18:13:59 <ByronT> that's no good
Mar 22 18:14:25 <[g2]> yes, dropbear switched some option iirc
Mar 22 18:14:27 <ByronT> (and I saw you reply in the other channel _after_ I replied... ;) )
Mar 22 18:17:19 <novacane_22> yeah, the root password is still blank (I have serial access), but ssh does not accept it
Mar 22 18:20:38 <[g2]> novacane_22, if you've got serial then you can just #passwd
Mar 22 18:20:46 <[g2]> and set it to something 
Mar 22 18:20:48 <[g2]> then ssh in
Mar 22 18:26:18 <novacane_22> yeah, the serial was not hooked up, the slug was at the other end of the room and I was being lazy
Mar 22 18:26:33 <novacane_22> but yeah, I hooked up the serial and set a passwd
Mar 22 18:27:16 <[g2]> unfortunately I think the latest dropbear has an option not to allow blank passwds
Mar 22 18:27:25 <[g2]> which default to not allow them
Mar 22 18:27:40 <[g2]> we haven't explicity re-enabled that or set a default password
Mar 22 18:27:56 <[g2]> I just ran into it yesterday or this morning
Mar 22 18:28:01 <novacane_22> yeah, I now remember seeing something about that in the last few days
Mar 22 18:28:20 <[g2]> I think John Bowler mentioned it in the ml
Mar 22 18:28:32 <novacane_22> yeah, that is were I saw it
Mar 22 18:31:58 <ByronT> recommendation that we go ahead and set root password to "OpenSlug"
Mar 22 19:30:29 * ByronT is away -( be back later )- at 09:31p -( P:On / L:On )-
Mar 22 20:03:56 * ByronT is back -( be back later )- gone 33 min 26 s
Mar 22 23:39:57 <perlguru> morning
