<0> man, **** you
<1> well there's a place for C
<0> C is fine, lern2code
<1> like databases for example
<1> at my work we use mysql, that's written in C
<2> c++ is very hard
<0> is not
<1> because that's something where performance really needs to be optimized to the level of individual allocations of memory
<0> cry more nub
<0> (can you tell I want to play WoW right about now...?)
<1> tweek i think C++ requires a lot of experience to be good with
<1> haha
<1> i dunno i hate the programming language debate where people who dont' know much (not you tweek you obviously know stuff)
<0> most people that use 'C++' at a student level (and most profs that are used to C) use it as C with std::cout
<1> come in like java is too easy in order to program you must do everything the hard way like the zen master
<0> and maybe a cl*** or two instead of a struct
<1> screw that man, i took my operating systems cl***es in school, i know how all this stuff works under the hood
<1> i just don't have to be constantly dealing with it
<2> so if you go beyond that number
<2> does it mean you did something wrong
<1> i don't want to do like malloc, dealloc and all that
<0> beyond what number?
<0> I do - more control over the OS' management of memory
<0> including swapping
<1> tweek what do you work on?
<0> nothing, I'm a student :)
<0> that's why I'm singing C's praises
<1> hahaha well you're smart
<1> but yeah
<0> in fact, right now there's at least three projects I'm stalling on
<1> if you get a job 90% odds are it won't matter much how fast your **** is within an order of magnitude
<1> as far as CPU and memory consumption
<0> code legibility is important though
<0> and modularity
<1> because they're dwarfed by I/O request blocking
<1> yeah that's why i like java instead of C :)
<1> code legibility and modularity
<0> most coders don't realize how *big* the datasets that clients are going to be working with are
<0> and until they think on those terms they won't be able to code correctly
<0> when you're in C you have to think about every line
<0> ASM moreso
<1> yeah depends where you are, like we have a 13G dataset in one place, a few multi-million row database tables
<0> in Python and ****, it's like, '**** it, let the interpreter figure it out'
<1> but that's all in the database, it's mysql
<1> we just upgrade to the new version when it comes out
<0> my professors work with gigabytes of data at a time...
<1> our application specific code is dealing with small amounts of data per request
<1> lots of that in tandem
<1> a ****load actually
<1> but it scales
<1> just keep throwing more machines behind the load balancer
<0> one of my neural net profs speaks of like three-dimensional Karnaugh maps with like 10 million nodes
<1> it's cheaper than saving 5k of memory here and there
<1> with a lot of labor
<0> well, not Karnaugh
<0> the self-organizing unsupervised one
<1> yeah i wrote a NN in college
<1> just a 2-d one
<0> I wanna know how the **** backprop works :(
<0> if I knew I could finish this **** in under a minute
<1> but it was pretty slick i had a cl*** that built an arbitrary sized one
<1> mine did that but i forget how it worked
<1> basically it was comparing the correct answer to the one you got
<0> every time I've seen it explained they go 'the error propagates backward through the network'
<1> and pushing the error back through the network
<0> and you're left wondering, 'wtf dude?'
<1> hahaha
<0> so they give some equations with variables you've never seen in the entire book before
<1> no i actually remember it
<1> damn if we had a whiteboard i could show you
<0> and then you're like '****ing hell'
<1> i don't remember the equations i just bootlegged those
<1> but as far as following the pointers back through the network
<0> the 'cookie-cutter' backprop algorithm ***umes a lot
<1> it's like if this bit was right, leave it alone, if this one was wrong, see what fed into it and distribute fault for the error appropriately
<2> unfounded thier a whiteboard on google
<1> and so on, going recursively back through the network
<2> unfounded thier free online w hiteboard you can use
<0> so unless you're using exactly the same one, and exactly the same code, you *need* to understand the equation and where it's coming from
<1> yeah tweek do you get what i said just there?
<0> gopp: you don't do whiteboards online...
<0> yeah, I know that much
<2> tweek whynot
<0> gopp: a 'whiteboard explanation' has to be in person
<0> just wouldn't work out otherwise
<2> usse mics
<2> and whiteboards
<1> that's way too much setup effort
<0> yep
<1> plus i don't remember it well enough
<1> to be wroth that setup
<1> lemme see if i have my code still
<1> sorry tweek it's in java :)
<2> so you cheated in college unfounded
<1> haha no i wrote this myself
<2> but you bootleged the equation
<1> oh yeah that was for the sigmoid function
<1> i wrote the whole actual program i just took one equation which was more a math thing than a CS thing
<1> but yeah i didn't cheat really to speak of
<1> lots of people did
<2> http://www.microsoft.com/windows/netmeeting/features/whiteboard/default.asp
<1> it's so eays to google a common CS problem and get the code
<2> common
<2> ???
<2> or the same
<0> frequent
<1> like towers of hanoi
<1> i'll admit i copied that one off the internet
<0> if I wanted code I could get it
<1> i was a first semester CS student and you expect me to get this right?
<0> I did Hanoi in my sleep in third grade
<2> http://news.thomasnet.com/images/large/009/9033.jpg
<1> haha
<1> but did you write a recursive algorithm to solve it
<2> most cs student cheat
<2> I think most cs deparment know this
<2> hmm
<2> acutally thier is no whiteboard online software
<2> wow strange I would think thier was a program you can draw online with others watching
<2> the only one is netmeetings
<0> people still use that ****?

<3> Symantec took Ghost and made a better program, Called Norton Save and Restore.
<3> It does everything ghost does but its better and easier for smaller backups.
<3> Does degree of compression effect data integrity or just speed of back up ?
<3> Anyone know, Is anyone here ?
<4> speed
<3> But its safe as for data integrity ?
<3> Hmm I think Ill do a very deep compression then.
<2> I would think speed
<4> yes, especially if it's hardware compression
<3> Well its software compression.
<4> i meant for speed. hardware compression is much faster
<2> how do you do software compression
<4> built into backup programs
<2> No I mean, to a tape drive
<2> or cdr FreeMrkts or how
<3> Its a program which ghosts your Main Disk and then your other discs if you want. And I dont mean ghosted as in the vernacular of Vine Deisal in "The Chronicles of Rid****" and "Pitche Black" but I love those 2 movies ;)
<2> if you have 200 gig drive, how do you compress that to a cdr
<4> with magic
<2> or will you back them up to a dvdr
<2> wow that cool
<3> Gopp, im backing them up to hard drive in DVD size units. Then I am transferring them all to DVD and then I am erasing the ones on my HD
<2> so I could have a save / restore on a dvdr dual layer
<2> and anytime my computers go bad, I just put the dvdr in the drive
<5> lol gop you cant get 200gig of data onto a 750mb cd
<3> I have DVD DL but Its cheaper just to buy 100 DVDs for 4.7 gigs at about .30 eash
<3> .30 each
<5> never ever
<5> lol
<2> Nemes I kno
