<0> azi: you can use gv
<1> lindi-: yeah, just realized that
<1> http://www.gumbusters.com/home.html
<2> nite
<3> is level 30 the end or just another puzzle?
<3> eleven: you read the spoilers, no? can you tell me if 30 is the end
<0> domen: which wargame is that?
<1> lindi-: it's not a wargame
<0> azi: ok, what then? ;)
<1> lindi-: let' me see if i can provide you the link
<1> n.nfshost.com
<1> ^^
<0> javascript :(
<1> no no
<1> no javascript
<0> $ wget -qO - n.nfshost.com|grep -i javascript
<0> <script language="JavaScript">
<1> the point in the game is FAR away from hacking javascripts
<4> domen: I haven't read the spoilers, but from what I know 30 is the end
<3> eleven: ok. thanks. i was fun, kind of. vortex is better! :-)
<2> hoi
<1> heya
<2> enjoying the weekend?
<1> very much,you?
<2> well yeah
<2> do you know about serial signals by any chance?
<1> this looks like some electronic stuff? :)
<2> well
<2> just a little
<5> just ask. ;P
<2> well
<2> about end of previous char, and start of new one, on the line
<2> at the end of a char/frame, you have a stopbit (mark)
<2> after that is a space
<2> I am guessing line *must* go to mark (idle) again before next char is started?
<2> in other words: can the space after the stop bit be the start bit of a new frame ?
<2> I am really guessing 'no'
<2> I am making software uart
<3> michai: http://beyondlogic.org/serial/serial1.htm#40 says start can follow stop bit(s) immediately
<2> doh, didn't check there :\ thx
<2> ah see
<2> line is low after stop bit
<3> you wanted to do it without stop bits?
<2> well no
<5> yup.
<2> it will go high (always), then start bit comes, and then etc ?
<5> i have been writing sw_uart for AVR microcontroller..
<5> s
<2> aha
<3> Ravi: there are AVRs w/o uart? ;-)
<2> I am exactly doing that
<5> michai: http://netlab.servebeer.com/~ravi/icard/sw_uart.c
<5> my software uart with seca2 implemented protocol ;>
<5> domen: in that project, i needed more than one uart.
<5> domen: and uart baud rate was 'external-clock-dependent' :P
<6> .o(copy, paste, send to patent office, become a millionaire)
<2> hah
<5> ;-]
<3> Ravi: ah. and no README or something on that url you gave :-P
<5> domen: it was top secret code ;P
<2> Ravi, you poll for startbit in timer isr? I was planning on using external int
<5> michai: yup, timer generates int 3*faster than uart baud rate and i`m detecting start bit very easy.
<2> yeah
<5> that strange variable 'tcnt' is modulo 3 counter ;P
<2> problem is, I want to use a cheap-*** internal rc clock to avoid crystal. I figured that with < 5% deviation, you can do that
<2> what I want to do is: wait for start bit (external int), time to 1.5 bits ahead, then start polling at 1x bit time intervals
<2> my concern was that the error in the clock became bigger when more characters are received head to tail
<2> but, if there's a start bit before each, it doesn't matter
<7> I'm GAlexander.
<2> ok
<2> Ravi, I'll look some more at that, thx
<5> np. 3xfaster polling is recommended
<5> if you poll slower, you can lose synchro.
<2> I'm using external int, right...
<7> bye bye
<5> mmkay
<5> <-back to avrstudio :(
<2> what are you doing now?
<8> haha
<8> :)
<9> vitamin d
<8> lol
<9> ruls
<8> :)))
<9> vitamin c sux
<9> :)
<8> kej am veze :)
<3> wtf
<8> ma
<10> *sigh*
<8> :))
<5> master that controlls air conditioning systems, and communicates with < 32 slaves (controllers) via rs485 bus.
<5> michai: ^
<5> ;)
<2> ok
<2> commercial I spose ?
<5> project for money. ;)
<5> yup.
<2> very nice
<2> rs485 software you did yourself too?
<5> Tobe: ;)
<10> Ravioli :)
<5> michai: yup, but it is very similar to rs232.
<10> Vitamin C
<5> michai: you can use standard uart with suitable protocol
<10> that was something new
<2> Ravi, I thought you need arbitration and what not
<2> or do you use a chain
<2> or ring
<5> michai: and convert logic-states ttl->rs485 by f.e. MAX485
<2> laters
<11> Let's say I'm downloading a file, I select() and read byte by byte, what is a reasonable amount of bytes that I can write to disk, I'm concerned on how much bytes to write, becouse when I'll write to disk every single byte (and a file will be let's say 200Mb long), I'll waste the resources, or it doesn't matter?
<11> How much is normally written to disk?
<6> you know that you have caches?
<11> hmm?
<6> I doubt that you can write to your disk.
<11> yeah, I do cache in memory
<6> it will get cached
<11> mhm
<11> ahh yes, now I see
<6> and the driver/cache algorithm will wait until there's enough data to write
<11> forgot about it.... it's normaly around 4mb as I recall
<6> that doesn't mean your question has no impact at all
<6> I just _guess!_ it's not that much
<6> (for reasonable values)
<11> :)
<11> So what do you mean by saying that my question has no impact at all ?
<6> benchmark it with 4 8 and 16kB blocks
<6> I said "doesn't meant"
<11> yes I see
<2> no you didn't
<11> so what impact it has?
<6> I_v0: small one I'd say
<6> michai: did, too!
<11> <6> that doesn't mean your question has no impact at all
<11> ;-)
<6> I_v0: yes?
<11> no, it was for michai ;)
<6> then put his name in front of the sentence ;)
<11> nvm
<6> michai: *slap*
<6> like this ;)
<11> buehehehe
<11> ;-)
<11> ok ok
<11> ;>
<2> michai, *slap*
<6> ha
<6> fool!
<2> :(
