Ulimitem omezit konkretnimu zlobivemu uzivateli nebo radeji vsem
pocet spoustenych procesu, pripadne velikost zabrane pameti atd.

Kdyz jsem si na puvodni priklad udelal spesl konto,bylo to s
vedomim,zkusime,co by mi tu mohl nekdo pustit a co by mohl napachat. Pocitac
chvilku nereagoval,ale OOM killer zareagoval a nakonec sejmul i ten spravny
proces. A vim,ze mi tu chybeli ulimity pro uzivatele. A neboj,nepustim si
nejakou nepruhlednou binarku,tady do toho jsem videl jen chtel vedet jak
presne se to zachova ;-)

Jojo,takze si vzdycky pred pouzitim noveho programu prostudujes zdrojaky apod?

Ja zas zkousel takovou vec, ze sem v Ccku napsal program, kterej mallocnul
mego (pak ho cely necim prepsal (Linux je s tou spravou pameti dost potvora))
:-) a pak dalsi a dalsi v cyklu. Server vzdycky dava a dava, pak zacne
odswapovavat, pak uz je vsechno na swapu, pak je swap plnej a pak uz s tim
neudela nic ani root. Jediny co to zachrani je ^C toho procesu, ale musi se
reagovat vcas. ;-) I tak se pak system docela dlouho zotavuje (vraci veci ze
swapu do pameti). Dal sem si tam pak pauzu, ze prvnich x mega to veme rychle
a pak po megu. Na procisteni pameti je to fakt dobry. B-) Pohled do topu je
impozatni. B-))
Nakonec sme to vyuzili, kdyz kolega na serverech nastavoval ulimity..tak se
to docela hodilo. Pridelal sem tam hlasku "Uz to nejde..." a tim se to pekne
otestovalo. B-)
Roumen
P.S. Na otestovani:
#include <stdio.h>
#define SIZE 1
int main(int argc,char *argv[])
{
char *p;
int counter=0,f;
while(1)
if(p=(char *)malloc(SIZE*1024*1024))
{
counter++;
printf("Alokovano:%i (%iMB)\n",counter,counter*SIZE);
for(f=0;f<=SIZE*1024*1024;f++)
p[f]='a';
if(counter>10)
getchar();
}
else
printf("Uz to nejde...(%iMB)\n",counter,counter*SIZE);
}

Jeste sem si vzpomnel, ze prave tehdy nas delalo na serveru treba deset. No a
kdyz sem si chtel pustit SO, tak to chtelo (placnu) 40 mega a ono to tak po
ruznu cukalo a tak. Takze sem nasadil tady ten svuj cistic, odswapnul sem
kolegum 70 mega a pak teprve pustil SO a jak hezky svihaly!! :-)))))

Title: XFree86 versus Xouvert
Xouvert je jmeno Babylonske bohyne otevrenych oken, drevenych nastroju na
kopani a mesicniho svetla. Jaka je souvislost jejich tri kompetenci asi nikdo
presne nevi, ale ted se stala take patronkou nove nezavisle experimentalni
vetve XFree86.
Zakladatele (a nejen oni) maji pocit, ze vyvoj XFree86 je prilis uzavreny,
nepristupny mozne komunite vyvojaru a tedy i pomaly a neschopny udrzovat krok
s potencionalnimi trendy a s vyvojem grafickych ovladacu.
Na druhou stranu jde opet o dalsi priklad tristeni sil opensource komunity
- tady teprve pozname, zda je to dobre, ci spatne.

Title: Arcanum of Human Genome Revealed :)
For many years molecular biologists have been mystified by the fact that very
little of an organism's DNA seems to serve any useful function.
Mystery is solved.
The reason why only 30% of human DNA performs any useful function is that the
rest of it are comments.
Once we decode a typical human genome, we see that the contents begin as
follows:
===
/* HUMAN_DNA.H
*
* Human Genome
* Version 2.1
*
* (C) God
*/
/* Revision history:
*
* 0000-00-01 00:00 1.0 Adam.
* 0000-00-02 10:00 1.1 Eve.
* 0000-00-03 02:11 1.2 Added penis code to male version. A bit messy --
* will require a rewrite later on to make it neater.
* 0017-03-12 03:14 1.3 Added extra sex drive to male.h; took code from
* elephant-dna.c
* 0145-10-03 16:33 1.4 Removed tail.
* 1115-00-31 17:20 1.5 Shortened forearms, expanded brain case.
* 2091-08-20 13:56 1.6 Opposable thumbs added to hand() routine.
* 2501-04-09 14:04 1.7 Minor cosmetic improvements -- skin colour made
* darker to match my own image.
* 2909-07-12 02:21 1.8 Dentition inadequate; added extra 'wisdom' teeth.
* Must remember to make mouth bigger to compensate.
* 4501-12-31 14:18 1.9 Increase average height.
* 5533-02-12 17:09 2.0 Added gay option, triggered by high population
* density, to try and slow the overpopulation problem.
* 6004-11-04 16:11 2.1 Made forefinger narrower to fit hole in centre of
* CD.
*/
/* Standard definitions
*/
#define SEX male
#define HEIGHT 1.84
#define MASS 68
#define RACE caucasian
/* Include inherited traits from parent DNA files.
*
* Files must be pre-processed with MENDEL program to provide proper
* inheritance features.
*/
#include "mother.h"
#include "father.h"
#infndef FATHER
#warn("Father unknown -- guessing\n")
#include "bastard.h"
#endif
/* Set up sex-specific functions and variables
*/
#include <sex.h> /* Kludged code -- I'll re-design this lot and re-write it as
a proper
* library sometime soon.
*/
struct genitals
{
#ifdef MALE
Penis *jt;
#endif
/* G_spot *g; Removed for debugging purposes */
#ifdef FEMALE
Vagina *p;
#endif
}
/* Initialization bootstrap routine -- called before DNA duplication.
* Allocates buffers and sets up protein file pointers
*/
DNA *zygote_initialize(Sperm *, Ovum *);
/* MAIN INITIALIZATION CODE
*
* Returns structures containing pre-processed phenotypes for the organism
* to display at birth.
*
* Will be improved later to make output less ugly.
*/
Characteristic *lookup_phenotype(Identifier *i);

...and so on.
