[03:46]<kuggys>MD5 is still strong... if the Oechslin attack is the one I think you're talking about, it's very non-trivial to make a collision.
[03:46]<kjr>Oechslin is a time/memory tradeoff... you can find implementations labelled "rainbow tables"
[03:47]<kjr>it also depends on what you're judging it against
[03:47]<kjr>Kunnis: MD5 is now considered weak, but an "acceptable risk"
[03:47]<kuggys>Yeah, it's still a non-trivial attack.
[03:47]<kjr>most people didn't put much trust in it anyway
[03:47]<kjr>an Oechslin attack can be trivial... it depends on what's going on
[03:47]<kjr>it does require the hash in question though
[03:48]<kjr>Kunnis: as they start to distribute the dictionaries it'll only get weaker
[03:48]<kuggys>Yeah, it's a distributed attack...
[03:48]<kuggys>err Is it a distributed attack?
[03:49]<kjr>nothing says it can't be
[03:49]<kjr>the vulnerability lies in having hashes precomputed - it doesn't matter where they come from
[03:49]<kjr>they just need to be accessible in a manner to allow a user to look it up
[03:50]<kjr>nothing says you can't distribute precalculation, or even storage
[03:50]<kjr>storage is (by identity) the weakness of the attack
[03:51]<kjr>there are other ways to attack it, but you're right - engineering collisions can be difficult
[04:06]<jdvgdjgcgd>http://kevin.mesiab.com/myspacetracker/tracker.aspx
[04:06]<jdvgdjgcgd>click on my ad
[04:07]<jdvgdjgcgd>help me get rich
[04:16]<mupmvz>whats the highest qualtiy ImageFormat ?
[04:16]<kjr>nothing wrong with PNG
[04:16]<mupmvz>trying to reduce an image by a factor of 12 and its crap once i get that small
[04:17]<mupmvz>tried png and had no luck
[04:17]<vufvuzn>define "crap" (perhaps with some example images)
[04:17]<zndy_wjfnz>mufdvr: what's the current size?
[04:17]<mupmvz>starting size is 640x240
[04:17]<v2z>image format won't dictate how an image will look scalled down by a factor of 12, the resampling method will...
[04:17]<mupmvz>and im trying to go to like 53x20
[04:17]<vufvuzn>you realise of course that a small image just can't have much data.. are you sure you're observing a problem with the image format, and not a problem inherent in the size you are creating?
[10:28]<v2z>can i store an XML schema in an object and validate an XmlDocument against it?
[10:28]<v2z>and if so, what is that object?
[10:32]<cgud>tbr, have you looked at XmlValidatingReader?
[10:33]<v2z>i have, but i was hoping to validate an object already in memory and modified from the original file
[10:34]<zgzzcydjvgev>write it to a file, then validate that
[10:34]<zgzzcydjvgev>then delete the file
[10:35]<v2z>that's nice and dumb
[10:35]<v2z>what if my application doesn't have write permissions
[10:36]<cgud>tbr, are you using 2.0?
[10:36]<v2z>yes
[10:36]<v2z>i suppose i could mimic an input stream from the object
[10:36]<cgud>Then XmlValidatingReader is obselete. Use XmlReader. You can use an overload of the Create method to make it read from a stream and perform validation
[10:41]<v2z>where?
[10:41]<v2z>i see no place for a schema?
[10:44]<v2z>ah
[10:44]<v2z>i got it
[10:44]<v2z>thanks
[10:44]<v2z>god damn msdn2 is a BEAST
[10:44]<v2z>each page is like 2MB and it feels the need to attempt to transition from one page to the next
[10:48]<dzzctzrrzg>19:44 <tbr> god damn msdn2 is a BEAST < i concur
[10:48]<dzzctzrrzg>fortunately i never have to use it if i don't want to
[10:50]<vjvrfd_fjsv>how is that?
[10:50]<cgud>It can be installed to the local disk, totaly_lost
[10:50]<vjvrfd_fjsv>offline msdn sucks also, with their sloooooooooooooooooow search
[10:50]<dzzctzrrzg>heh
[10:51]<vjvrfd_fjsv>yeah right
[10:51]<v2z>yeah if you have like 20GB to spare
[10:51]<vjvrfd_fjsv>and filtering is very very good there
[10:51]<vjvrfd_fjsv>it's very fun to go through like 20 checkboxes each time you want an advanced search...
[10:53]<v2z>i wouldn't mind msdn2 as much if they did something about the page load time. compression or something, not everyone has a huge pipeline to the internet
[10:53]<cgud>I only have Express installed. With all Express products, plus documentation, comes to just under 1GB
[10:53]<dzzctzrrzg>or just if you didn't have to load the contents pane every time
[10:53]<vjvrfd_fjsv>well full msdn eats up 3.2 GB
[10:54]<dzzctzrrzg>so?
[10:54]<cgud>Not bad
[10:54]<dzzctzrrzg>what else are you going to use it for?
[10:54]<vjvrfd_fjsv>and vs.net another 2GB
[10:55]<dzzctzrrzg>my vs folder is 800mb
[10:55]<vjvrfd_fjsv>what kind of vs?
[10:55]<cgud>totaly_lost, how large is your HD?
[10:55]<vjvrfd_fjsv>CGuy 160 GB
[10:56]<v2z>4am, sleep, later
[10:56]<dzzctzrrzg>.net 2003
[10:56]<dzzctzrrzg>nn
[10:56]<vjvrfd_fjsv>well i'm talking about 2005
[10:56]<cgud>Dedicated development machine?
[10:56]<cgud>Night tbr
[10:56]<fyfuym-syfggag>later tbr
[10:56]<vjvrfd_fjsv>CGuy well .. quite new, asked for it when we ordered vs.net 2005
[10:57]<vjvrfd_fjsv>on my home laptop centrino 1.6 and a slow disk .. if you try to work with larger typed dataset .. ahrr .. sloooooooow
[10:57]<cgud>Ah, so you don't like having to buy such a large drive?
[10:57]<vjvrfd_fjsv>CGuy u mean... ?
[10:58]<cgud>I'm trying to understand why you consider 5.2GB for VS as large?
[11:00]<vjvrfd_fjsv>em .. where did i say it's large?:) i just stated the facts, how much space it eats up
[11:00]<dzzctzrrzg>mm space chomp chomp
[11:01]<vjvrfd_fjsv>for my home laptop, it's a bit of a problem , so i don't have msdn there :(
[11:04]<afd>CGuy: because more than 2/3 are useless? ;)
[11:05]<dzzctzrrzg>truth
[11:05]<afd>CGuy: the express version provide almost the same basic functionality
[11:09]<dzzctzrrzg>any of you guys know anything about drawing strings?
[11:09]<jjz_fzzjzn>a bit
[11:09]<jjz_fzzjzn>if you managed to get your question out in the next 30 seconds I might be able to help you before I pass out on my nearby bed
[11:09]<dzzctzrrzg>it'll take longer
[11:09]<jjz_fzzjzn>try hard
[11:09]<dzzctzrrzg>because i cba
[11:09]<jjz_fzzjzn>cuban?
[11:10]<dzzctzrrzg>why does my string drawn from a graphics object look different from one in a textbox?
[11:10]<dzzctzrrzg>same font an all
