[Leaf-devel] I need advice about some decision...
project team MOLE ,electronics engineering department Kang Won National University, KOREA Dear developers It was very helpful studying your website. Firstly, I appreciate that. We are designing Linux Router Project.I want to develop Linux Router with 1-floppy but we had a serious problem. so I would like to ask you to help us . My Linux router system must have following requirements. spec: 1 floppy Boot/root Linux system 2 support Ethernet(TCP/IP) * 3 Qos in Ethernet(not for ATM ) - Router must control band width by each User(IPs on Ethernet Network) when network is busy ,the system must guarantee Minimum Band for higher priority user. and when other case each IP could communicate Maximum for the extra. and here I face some serious Problem. prob: 1.how could I design Qos function in Ethernet? I could't find any text for the Qos in Ethernet. all is for ATM. someone adviced that I must edit TCP layer ; tcp_input.c/tcp_output.c but I heard I could design such a function(Qos in Ethernet) just on IP layer. ;ip_input.c ip_output.c I am sorry to bother you but I look forward to hearing from you. your sincerely charlie _ Àü¼¼°èÀÎÀÌ ÇÔ²²ÇÏ´Â ¹«·á À¥ ¸ÞÀÏ ¼ºñ½ºÀÎ MSN HotmailÀ» ¸¸³ª º¸¼¼¿ä. http://www.hotmail.com/ko/ --- This sf.net email is sponsored by: OSDN - Tired of that same old cell phone?

Re: [Leaf-devel] Webbased Configuration
some remarks about using forth: - certainly forth is missing all that nice pattern matching like awk or perl, all this has to be coded. Well, C is missing these as well, until you load a massive standard library :) - I assume that even arrays are not available in forth Not as part of the core language you'll get with the 10-20K interpreter, but you can easily add words to manipulate arrays. - because forth uses very unusual semantics (reverse polish notation) it is not easy to understand and to maintain (you have always to keep in mind, what is in this moment at which position on the stack). Like perl makes sense? I can't read most perl code becuase of all the implicit file-handles and data sources...I see the code that modifies stuff, but I don't know what it's working on. Too many $.@/ things for me to keep straight. Each language has it's idosyncracies... mawk is 49K compressed perl4 is 136k compressed AFAIK, neither can do direct linux system calls, and both require another apx. 500K (compressed) C library to function.

Not as part of the core language you'll get with the 10-20K
interpreter, but you can easily add words to manipulate arrays.
That is correct, but you have to take these points in acoount,
when comparing sizes. You can get a basic interpreter, that
fits in 2k of memory. It has less features than forth but it is
even smaller.
- because forth uses very unusual semantics (reverse
polish notation) it is not easy to understand and to
maintain (you have always to keep in mind, what is in
this moment at which position on the stack).
Like perl makes sense? I can't read most perl code becuase of all the
implicit file-handles and data sources...I see the code that modifies
stuff, but I don't know what it's working on. Too many $.@/ things for
me to keep straight.
Each language has it's idosyncracies...
The most important difficulty with forth is RPN. An example:
func(y/(5+3*x+z), y/6, y*y)
is in RPN
y 5 3 x * + z + / y 6 / y y * func
How long do you need to verify, if the two lines are the same?
y z 5 x 3 * + + / 6 y / y y * func
Is this the same? How long do you need?
Some years ago I have done a lot of postscript programming for
high quality typesetters. Postscript also uses RPN. I think
I would not have big problems reading forth.
Readability is a question of coding style. In any language you can
write code that is not easy to understand.
while() print
is the same as
while ($line = STDIN)
{
print $line
}
but the latter is more easily to understand.
It is also a question of experience with the language.
My boss is a experienced C programmer on DOS and embedded systems.
But when he sees a script line like this
[ $DEBUG ] echo `basename $file`
he asks me: What the hell are you doing here?
BTW, the most of this $%@... are an implicit type declararion
like in fortran, where all variables starting with [i-n] are
implicit integers.
mawk is 49K compressed
perl4 is 136k compressed
AFAIK, neither can do direct linux system calls, and both require
another apx. 500K (compressed) C library to function.
Both need only libc, which is needed anyway and libm, which is
38k compressed.
AFAIK web configuration is only manipulation of script and config files.
So I can see no necessity for any system calls, but I may be wrong.
At the moment I have not the time to get involved in this project,
so this is only my opinion and to share available information and
experience.
If someone wants to play around with perl4, I can make the lrp
publicly available. It passes the tests in the makefile and I
tested the server example of the manpage on a bering system.

Readability is a question of coding style. In any language you can write code that is not easy to understand. snip but the latter is more easily to understand. It is also a question of experience with the language. My boss is a experienced C programmer on DOS and embedded systems. But when he sees a script line like this [ $DEBUG ] echo `basename $file` he asks me: What the hell are you doing here? Exactly...familiar languages look normal, and unfamiliar ones look wierd. I can usually pick up a new computer language in about 1-2 weeks (to the point I'm writing code rather than crawling through reference manuals checking on syntax :), and be coding very well in 3-4. I really don't care which language gets picked, but it should be selected on it's merits for the task at hand. I think part of the problem is I have different tasks in mind than several other folks... If someone wants to play around with perl4, I can make the lrp publicly available. It passes the tests in the makefile and I tested the server example of the manpage on a bering system. Please make your perl4 package available. At the very least, that's the lightest perl implementation I've heard of for LRP, and I'm sure someone will find it useful.

[Leaf-devel] UML Bering - sh: can't access tty; job control turned off
Howdy all, I have run into another problem with using UML. I am trying to boot up using bering-1.0-rc2 and I get the message... sh: can't access tty; job control turned off I have tried using the 2.4.28-21 and the 2.4.18-45 kernels and both drop to a # prompt after hitting that message.
