<0> TCA!
<1> msg me if you can ***ist. Having trouble with a 15 day demo :o)
<2> 15 day?
<2> ?? movnti
<3> Oh, I forgot the answer
<1> Sorry!
<4> hmm
<4> its quiet as usual..
<5> We're *********ing furiously
<4> oh then don't let me disturb you
<4> TCA, what is your opinion of the best way or algorithm to manage allocated memory?
<5> Uhm... don't ask me that. Malloc() is one of the most complicated things to write
<4> i was writing and writing my little OS code then i just froze with memory management..
<5> Yeah, good luck. There's no straightforward answer. No right way to do it.
<6> malloc efficiency depends on the type of data, and the type of operations. Without knowing exactly how it will be used, it'd tough to make a gp algorithm that performs well
<6> and if you want good performance AND efficient memory use, it's even harder
<6> fixed block allocators perform well for a lot of tasks, but they arent memory efficient, for example
<4> aye i was thinking of just fixed blocks of 4k pages to make it simple when i go into paging
<6> well i meant fixed blocks with various pools based on size of request
<6> usually on a page boundary
<4> so basically in the powers of 2 blocks
<6> yeah, it's fairly easy to implement too
<6> scale request to correct blocksize
<6> grab em off the free list
<6> if none on freelist, allocate fresh memory
<6> and free() can stick em on the free list
<6> which leaves you just the allocation question
<6> brk used to be the typical way, but these days mmap of /dev/zero is a more common way to allocate memory
<4> what is brk?
<2> brk sets the end of the data segment to the value specified by
<2> end_data_segment, when that value is reasonable, the system does have
<2> enough memory and the process does not exceed its max data size (see
<2> setrlimit(2)).
<2> brk, sbrk - change data segment size
<4> im also hammered on if i should use a table of representing blocks of memory or a list of free memory ranges, since if you are going to allow allocation smaller then 4k the list can grow large..
<4> hmm
<5> Yer site.. is blank.
<5> voider.. fix wisebot
<7> ?
<5> .dasm16 90
<3> TCA:
<3> -------------------------------------------------
<5> Mmhmm.
<7> rah
<7> ok
<7> i forgot to install nasm when i reinstalled the server
<7> ouch
<7> nasm emerging
<7> .dasm 90
<3> voider:
<3> -------------------------------------------------
<3> 00000000 90 nop
<3> -------------------------------------------------
<7> fixed
<7> heh
<5> But only rank 1.
<7> it's ok, it's enough to encourage me to write comments for an homework's code
<5> Seriously, though.. thank you.
<7> it was a pleasure
<5> You know.. I want to like linux. I really do. I installed SuSE.... and the install was nice. But linux is still unadulterated crap.
<5> Creating users crashed. Repeatedly.
<5> **** you, linux. **** you.
<7> ?
<7> how did you created users?
<7> i don't understand how this step can crash
<5> I used Kuser
<5> I don't understand how it can crash either
<7> rah
<5> No, wait. I can understand.
<7> never trust a graphical tool that you don't know what it does
<5> It's a crappy OS.
<7> man useradd
<5> I know how to add users manually. I don't want to do that any more
<7> kuser is'nt part of the os..
<7> you can't judge an os by the tools you decided to install on it
<5> **** you, KDE. **** you.
<5> I didn't actually decide to install that. It defaulted.
<5> And you're making excuses
<7> me?
<5> Your arm is on fire.
<5> I would be just as upset if MSPaint crashed repeatedly
<5> I would say, "**** you, Windows. **** you."
<5> However, it doesn't do this.
<5> Firefox, on the other hand, does
<7> heh
<5> Although I've learned that's actually flash 8.0
<5> So I don't fault Firefox
<5> much
<7> you can return to dos if you prefer ;)
<5> Good times
<5> The whole sum and collection of it is bad.
<5> No.. I shouldn't say that
<5> The install was very friendly for SuSE. Vast improvement over Fedora
<5> But when I can't do basic things...
<7> have you ever tried gentoo?
<5> Yes
<5> Don't get me started
<7> if you don't mind the install time, i think it's almost perfect
<5> I couldn't even get through the install
<7> i remember you told you were a unix guy, no?
<5> I am
<7> and you can't finish a gentoo install?
<5> I gave up after page 13 of the install manual, where I was cutting and pasting verbatim
<5> Why there wasn't a "Do all this crap for me" button still eludes me
<7> the most complex thing in the gentoo install process is probably the chmod, and it's far from hard to understand
<7> a stage3 is fast and easy
<5> I don't want to have to read 20 pages of text to install an OS
<5> Why you and every other kool-aid drinking linux weenie doesn't understand that I cannot fathom
<7> fathom?
<5> comprehend
<7> sry, i don't understand
<7> oh ok
<5> I'm not asking for much
<7> i'm not a linux zealot, or a wennie (i understand this word as zealot), but i use it because it does what i need
<5> Just a nice easy install with sane defaults (SuSE meets that requirement), and usable tools
<7> i just don't like that ppl continue to spread mis-conception like "linux is hard to install"
<5> When the tool presented to me doesn't work...
<7> or "it's impossible to create users in linux"
<5> It's not impossible, but I don't want to do it manually
<5> I've been doing it manually for 23 years
<5> Make it stop already
<7> what is less manually?
<7> kusers?
<5> That's the tool presented to me
<7> of a simple keystrokes?
<5> And had it worked, I would have been very happy
<5> But it didn't work
<7> useradd -g group,goup2, group2 username
<7> but i know you know
<5> [00:51] <5> I've been doing it manually for 23 years
<5> [00:51] <5> Make it stop already
<5> FreeBSD's adduser was perfect, and Kuser was very similar.
<5> Had it worked, I would not be here ranting about how crappy the whole lot of you are
<5> Get it? Don't tell me to do it a different way because the DEFAULT INSTALLED way FAILED
<7> i never tried/saw kusers, do i can't really talk
<7> it's just weird to see someone bashing on an OS just because a single tool failed
<5> I couldn't play DVDs either
<5> rlogin didn't work, and there's no option in /etc/xinit.d
<5> I could go on....
<7> heh
<7> ok
<5> It didn't detect my ethernet card.. it just detected the on-board
<5> The sound had a problem
<5> But I'm ignoring those because it's a production machine, not an entertainment device
<8> and it looked at you funny too!
<5> And it raped my dog and killed my cat
