<Dmi_> alive man, aliiiive!
<Battosai> ./kick dmi "REALLY? Let me fix that"
<Dmi_> heh
<Dmi_> hey Battosai :)
<Robspiere> what's the best way to get maildrop to forward emails to a different account? my way doesn't quite work
<Robspiere> i'm using an if statement with "to /home/user1/Maildir/.testdir"... which only forwards emails to that dir if the email is sent to user1
<loop_> anyone know how i can use sed to make this 12-03-05 look like 120305? I got to the point where i could replace the "-" with a blank space, but not sure how to remove that spaces and pull the numeric digits back by one to get 120305..
<dhartmei> s/-//g
<loop_> hmm... let me give that one a try.
<loop_> ok thanks- what i did wrong was 's/-/ /g'
<loop_> thanks dhartmei
<zeebee> I figured out what was causing the remote ssh freeze
<DocRadium> and?
<evils0n> pebkac?
<zeebee> the version of MPI I was using, was compiled for small clusters .. meaning it registers more memory per process
<zeebee> the underlying ***umption is that a small cluster is no larger than 64 nodes
<zeebee> but I was running this on a 512 node / 1024 proc cluster
<zeebee> each process was consuming in excess of 1.9G or 3.8G per node
<zeebee> the friendly kernel started thrashing and SSH froze as a side effect
<zeebee> it wasnt really SSH's fault
<Hawson> zeebee: I've heard rumors that there are ways to lock processes in memory.
<Hawson> I suppose you could compeltely disable swap, and that would have the same effect
<Hawson> if there's no swap file, you can't really thrash. :)
<tchang> hahaha Hawson
<Hawson> you think I'm kidding?
<tchang> it sort of makes sense it's just never ocurred to me before to do that
<Hawson> why do you need swap?
<Hawson> A: Because you don't have enough "real" memory
<tchang> I get alerted when swap starts being used on my boxes :P
<jez> Can anyone remember what the URL is for that funny cartoon guide to DNS, where a user tries to get porn
<zeebee> Hawson, these machines had no swap ..
<sandtrip> morning from the west coast
<Milamber> Mmm.. Just got back from a Sun thingy where they spoke about their new servers. Very neat stuff.
<Milamber> Or at the very least, convincing marketing pitch. ;)
<Mouring> The the gods of piety strike you down for ***ocating with the devils of marketing.
<dinomite> I have 10 ports digital box for sale..u can connect up to 10 monitors, keyboard, and mouse
<dinomite> oops
<dinomite> wrong window
<Mouring> $5.99 w/ shipping. My final offer.
<Milamber> One of the guys talking about CoolThreads though, seemed more like some geek who's absolutely sold to the technology/product than some sales guy.
<dinomite> asking for $70
<dinomite> made by ibm
<Mouring> coolthreads? Sounds like a bad cross of Hyperthreading and Coolrunning.
<AC-130U> Cool Runnings
<AC-130U> heh
<Mouring> Will we have Jamacians now doing our thread processing?
<AC-130U> yeah, really... :P
<AC-130U> (length wise)
<dinomite> read this: http://www.apa.org/journals/features/psp7761121.pdf
<Milamber> Mouring: https://www.sun.com/processors/UltraSPARC-T1/index.xml
<Milamber> Thats basically their coolthreads..
<Mouring> ugh. So it is Dual/Quad Core + Dual/Quad Hyperthreading.. Even after Hyperthreading has proven to be bad.
<Mouring> and I doubt this one chip will preform like 32.
<Milamber> The lower power/heat are nice factors.
<Milamber> They've done their benchmarks otherwise, seems pretty interesting.
<Mouring> mil, only if their benchmarks/preformances are realworld enough.
<Mouring> remember when Hyperthreading came out it shows m***ive improvements, but in real world applications it show little, and in some database configurations showed a m***ive preformance hit.
<Mouring> So I'm not sold on a product until I see real word 3rd party figures.
<Milamber> Well, the typical benchmarks/performance tests you see publicized by most other chip vendors, I don't remember the name of the test..
<Milamber> Oracle was also there pushing along, but obviously, those 2 go hand in hand..
<Mouring> the issue IIRC for hyperthreading was the CPU cache invalidation process...
<Mouring> By having the cache invalided it hurt too much.
<Milamber> Reports online here and there seem to agree as far as performance is concerned too. So it seems somewhat genuine hype.
<Milamber> Ah, spec.org.
<Mouring> spec rating is good for a general clue, but they don't show real world preformance.
<Milamber> I know what you mean though, for sure, I'd be curious in seeing benchmarks with actual applications also.
<Salmon> i'm impressed by the opteron dual cores though
<Salmon> pushing 7.5Gbs through 8 fc hbas on a peesee is pretty freaking amazing
<Yashee> Acetaminophen 325 mg, Dextromethorphan HBr 15 mg *AND* Phenylephrine 5 mg
<Salmon> i think sun is trying do what they can to get the perception that they are fast
<Salmon> they have never really been that fast
<Salmon> we then were 6800 based they were just 6800 based
<Salmon> and the sparc has always been way back on the speed curve but thats not why you buy sun
<Mouring> funny they would announce this now since Intel/AMD are rolling out quad core processors.. and working on eight-way cores.
<Yashee> Low power interests me a lot more than multi-core
<Salmon> i guess thats fine if everything fits in 1M of cache
<Salmon> ya same here yashee
<Yashee> CPU itself isn't really a bottleneck in anything I do
<Salmon> but we do need 8 way boxes so our only option from HP in peesees is 4 dual cores now
<Yashee> especially with L2 and L1 getting better
<Salmon> intel has serious bus and cache issues to take care of
<Mouring> yashee, for you maybe not.. for my work it is. The speed jump I saw from quad-Xeon 500mhz to dual-Xeon (threaded) 3.0ghz was impressive.
<Mouring> It showed that we needed the extra horse power.
<Salmon> mouring: that could have been bus speed too though
<Salmon> most quad xeons were 100 or 133mhz
<Salmon> 3.0 is probably 400mhz
<Mouring> could be.. <shrug> it is a web/database app.
<Mouring> with a ****load of badly written perl code.
<Salmon> ya for that it's probably the bus
<Salmon> and disks etc...
<Milamber> Salmon: Yeah, the Opteron servers looks pretty nice.
<Hawson> Milamber: they are
<Milamber> Has anyone tried one out, or using some actively at the moment?
<Milamber> Like with that 60 day trial program of theirs, heh..
<Hawson> activly using a v40z
<justaname> hello, could anyone help me with a regular expression ?(-:
<Yashee> Hawson: can I try to run btdownloadcurses on it, just to see how well it performs? :)
<Yashee> justaname; are we going to guess what regexp you're having issues with?
<justaname> i need something for the php function preg_match_all, it should match : {$abc12_abc123}
<Mouring> any ol' RegExp? Then here s/.*>(\1)<\/*./\1/
<justaname> until now i have this: /^[\{\$][A-Za-z0-9._-\]+[\}]$/
<Yashee> Mouring is in love with \1/ now hehe (which I've still not used :/ )
<Mouring> yashee, <shrug> For once it worked. I never use them in real life.=-)
<Hawson> Yashee: no. :)
<justaname> thanks, i will try it..
<Mouring> just, that regexp isn't useful to you (the one I wrote that is).
<justaname> hm, ok, then.. can you help me with my one: /^[\{\$][A-Za-z0-9._-\]+[\}]$/ i think the problem is near \$ ..
<Milamber> Yay, another silver for Canada.
<justaname> amm found an error-> better version: /^[\{\$][A-Za-z0-9._]+[\}]$/
<Yashee> justaname: what is -\ ? doesn't . mean * in regexp, so after ._ you need something to handle the final abc123?
<justaname> uuu i hate that &/&%$%=)%$&% reg exp stuff
<kalc> hey all, whats the best software raid for redhat AS EL ?
<Hawson> kalc: probably the stuff Redhat uses
<kalc> which is?
<Hawson> the best
<Hawson> Yashee: you noticed that too? :)
<Mouring> wow.. Canada is only 2 golds away from the US.
<Mouring> But they have a hard time leaving the 5th ranking.
<Milamber> I heard somewhere Canada's goal this year was 3rd place.
<Milamber> Which I thought seemed ridiculous at first..
<Milamber> But now seems not that bad at all.
<Yashee> Hawson: it's actually made the news up here heh
<Hawson> actually, it'd be cool if it *WAS* a CD. :)
<Yashee> full of insect porn!
<Hawson> have video footage of their winning run, or something
<Mouring> A gold plated CD
<Hawson> or insect porn, sure...
<Yashee> okay their video footage and insect porn
<Hawson> was it the Calgary medals that had crystal in them?
<Hawson> those were cool
<Yashee> probably.. if they were Canadian.. <evil grin>
<Yashee> hrmph
<Mouring> "will to wildly throw himself" .. Must create a nice split there to draw the reader's attention.=-)
<Mouring> /will/willing/
<justaname> ohh jea baby - i got it: /[\{\$][A-Za-z0-9._]+[\}]/
<Mouring> I love the smell of split infinitives in the afternoon.
<justaname> thanks for helping .. nice evening
