Why not ? Sendmail does that. If your mailserver is sendmail, it will accept the mails and then spool them locally, till the link is up.

Overflows
by q u a s i 05 Oct '02

05 Oct '02

ummm... People, as a separate discussion here is an idea [probably extremely lame]. There should be an allocation ramdomizer. Meaning say, if you require 100 bytes, then the randomizer should malloc memory from say 100-120 bytes at random during runtime. Now you may ask, why O why? Well when the [fixed] memory is allocated on the stack, peeps use it to overflow the buffer & corrupt return address of calling function - "Classic buffer overflow" as some like to call it. But if we have a variable allocated space the same overflowers will not have such an easy calculation - having a choice of 20 spots for the return address [in this eg]. Ofcourse it would be better to just check for input overshooting the buffers. But it was an idea anyway...! '-) quasi

RE:[ILUG-BOM] Not so Random
by Sankha Subhra Som 04 Oct '02

04 Oct '02

Nikhil, the term RNG is actually a misnormer the numbers that a RNG generates are actually pseudo random numbers, meaning they are reproducible and the generating function is known(hence they can be reproduced). Most of the RNG's we know of are LCG's(Linear Congruential Generators) They work on a simple recurrence relation r(i+1) = (A * r(i) ) MOD m MOD is the modulus operator. In ur case Considering that r(i), A and m are constant r(i+1) will also be the same each time u execute the program. A clever workaround will be calling srand() with the seed as the current system time. The ideal generators are those that have a period equal to 'm'. The period is the longest possible non-overlapping sequence of numbers generated by a LCG. the greater the period the more desirable is the generator(but the sequence of numbers generated is also important). The 'seed' is nothing but r(0) ie the first r on the RHS of the recurrence relation. The C library RNG is not that good in the sense that it has failed many theoretical and empirical tests. there are a lot of RNG'S that are much better than this generator and have whopping periods.They also provide the user with the ability to generate disjoint substreams of numbers using the same generator. Random number generation is a tricky process and needs a lot of mathematical intuition. And finally if you are looking for truly random numbers try weather data from internet weather stations.These are truly random. For a more thorough understanding read Knuth:Art of computer programming. Enjoy!! Sankha -- SANKHA SUBHRA SOM ATC - BIOINFORMATICS TCS KLK BUILDING.

What do Luggers think about the Kernel naming system?
by Bhargav Bhatt 04 Oct '02

04 Oct '02

I am sure most Luggerz have read the URL posted below. It refers to the Slashdot story on the naming of Linux Kernel. http://ad.doubleclick.net/adi/N339.slashdot.org/B1044957.3;sz=468x60;ord=10… Apparently, there is lack of consensus in the core Kernel developing team as to what the new kernel should be called. While some want to call it 3.0 as they believe that calling it 2.5 would do injustice to all the work put into it, the other believe that it should be called 2.5 as it represents only increase in performance and not changes in any of the sub systems. Linus, as usual, is pretty neutral. I for one believe that calling it 2.5 or 3.0 should not make any difference to people who are already using Linux since some time. However, calling it 3.0 would earn Linux some marketing advantages and improve it in the eyes of the IT honchos wo, at first sight, might believe, its a lot more *stable* and advanced than the 2.4 Kernel. I think it would be interesting to discuss this here and get your views on this? -- Bhargav Bhatt, Department of Applied Physics and Applied Mathematics, Columbia University.

Can someone having expertise on Kdevelop please explain me why does it require so long makefiles and what all things really go inside that makefile. How is it beneficial to my hand edited makefile. I tried figuring it out. But it was way too cryptic. I find it much better to hand edit my own Makefile. regards Abhijeet

Re: Not so Random

You might want to see perldoc -f srand # PERL random seed documentation. srand EXPR srand Sets the random number seed for the "rand" opera- tor. If EXPR is omitted, uses a semi-random value supplied by the kernel (if it supports the /dev/urandom device) or based on the current time and process ID, among other things. In versions of Perl prior to 5.004 the default seed was just the current "time". This isn't a particularly good seed, so many old programs supply their own seed value (often "time ^ $$" or "time ^ ($$ + ($$ << 15))"), but that isn't necessary any more. In fact, it's usually not necessary to call "srand" at all, because if it is not called explicitly, it is called implicitly at the first use of the "rand" operator. However, this was not the case in version of Perl before 5.004, so if your script will run under older Perl versions, it should call "srand". Note that you need something much more random than the default seed for cryptographic purposes. Checksumming the compressed output of one or more rapidly changing operating system status programs is the usual method. For example: srand (time ^ $$ ^ unpack "%L*", `ps axww | gzip`); <snip> etc. You should be able to write similar code in C. Amish.

[SNIP] i hadnt heard of obfuscation before i heard of the comptt. now how do i get curiosity in something i never heard of. plus if u are thinking that i picked up some code directly from the mailing list and reproduced it there, u r wrong. the code came up on the list a day after the contest. if i had done that i wud have got the 1st prize , as the guy who did get the 1st prize did very similar things to those that were dicussed on the mail. what i did was somethiong diff.... i #defined & re #defined functions like scanf, printf, for , while etc etc as coke, pepsi, chicken, paneer etc etc.and to do a simple things like printing a msg ,i jumped 4 functions and did that. my code was supposed to take a string from a user and print it char by char. i had 100 lines of code for such a simple thing. hope matters are cleared now and HOPE U R CONVINCED THAT EVERY THING WAS /FAIR/... gurpreet

japh (whats obfuscation)
by Satya 29 Sep '02

29 Sep '02

In perl, we have japhs. Here are two examples: @a=split(q,,,qq,hgNbueCe nxe\nWf agr ryUpr\,,);for($i=015;;){if($i>=@a ){last};$_=$a[$i++].$a[$i-0xe];y;[A-Ma-mN-Zn-z];[N-Zn-zA-Ma-m];;print} @q=split(q??,qq?,JAPH \nacehklnorstubsqrfcnorkjpfdjpmfehi\ ljpag?);$i=0x13;while($i<=@q){print$q[ord($q[$i++])-0141]} Equivalent to: print"JustAnotherPerlHacker,\n"; Now Philip will tell me the ',' should not be there. This one's from ASR, I forget whose sig it was in: $q=q($@@@#$$@#$$$#@%$@#@$#@@@#@#$$$$#$#$@$%$@@$#$#$@$#$@$$%$$$$#$@#@$@$#@$@#$# $@$);@c=split//,'0etianmsurwdkgohvf0l0Pjbxcyzq';$f=1;$s=0;for$c(split//,$q){if ($c ne'$'&&$c ne"@"){print $f?uc($c[$s]):$c[$s]if$c[$s];$s=$f=0;}else{$s*=2;$s ++;$s++if$c eq'@';}print" "if$c eq'%';}print "$c[$s],\n";#probably too general and Dave Brown posted this one in the same froup: print "xx/yy? ";$_=<>;m,([0-9]+)\s*/\s*([0-9]+),;$j=$1;$b=$2; $d=eval;$f=$d-int $d;$t=$f*$b;print int $d,$t&&" $t/$b","\n"; It's supposed to be some kind of math tutor. Now that I read it carefully, I think I see what he's doing. He said: =item Someone commented that even though Perl actually compiled and ran that, I had obviously just fallen asleep on the keyboard and that's what came out. =cut -- Satya. <URL:http://satya.virtualave.net/> A transistor protected by a fast-acting fuse will protect the fuse by blowing first.

contact between various LUGs
by Gurpreet Singh 28 Sep '02

28 Sep '02

hi i was in goa engg coll lately for a competetion and got to meet a few ppl.what i observed was that, the popularity of linux and the desire among the students to be thorow with linux was clearly evident. i spoke to students from goa and a few from belgam. these guyz do have their local lugs and do what ever bit they can. after talking to then it struck me that why no have some communication between the lugs. what i propose is that, since a lot is going on the lugs on the mailing list and these things are really useful, why not share the popular topics every week on each lug with the other lugs. what we can do is (manually/ or automatedly) select 5 most popular topics on the mailing list, pile up all the discussion on those topics in 1 mail and mail them to every lug so that we can have thier comments too... we may also share the "off the mailing list" activities of each lug. for further discussion on this i have invited a few students from goa lug and belgam lug to attend the workshop @ our college. just an idea.... plz comment gurpreet

Hi, You got divine hands :-). Though it worked, you should still allocate memory to arg itself for holding array of pointers. Something like arg = (char **) malloc(sizeof(char *) * 6); arg[5] = NULL; Amish.
