Auto-logout problem
by Raju Bathija 04 Oct '02

04 Oct '02

In RH 7.3, which I use on my computer, I get logs out automatically sometimes. I mean I get the login screen after few hours of inactivity. I use KDE. Does anyone know how this ((automatically logging out) could be stopped? Thanks. -- -------------------------------------------------------------------------- Raju Bathija | bathija(a)tifr.res.in | http://theory.tifr.res.in/~bathija -------------------------------------------------------------------------- Immigration is the sincerest form of flattery. -- Jack Paar

Well I will have to speak to organizers, as I have received many queries in that regard.

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.

What do Luggers think about the Kernel naming system?
by Bhargav Bhatt 03 Oct '02

03 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.

kdevelop makefiles
by Abhijeet 03 Oct '02

03 Oct '02

Hi I have used kdevelop for sometime. But I havent figured our the Makefiles part Even for a small program like "Hello World" It makes a Makefile of some 100 lines. 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

Thanks again for confirming your availability on 19th. Sincerely wishing more people to come forward as speaker.
