Randomness
Hi,
I am very new to R and cannot seem to find how it generates random numbers. I
am currently involved with a project that requires a random number generator
and have developed one. I am, however, unsure of just how random it is and was
wanting to compare my generator with that of R (as well as others).
If anyone knows how the random numbers are generated or have any ideas on
testing or

Error loading mfc42.dll - failed (error c000007b)
:D Hi,
I installed wine on ubuntu 10.10 to run a windows program as reported here (http://appdb.winehq.org/objectManager.php?sClass=version&iId=22133&iTestingId=59338).
After few trails I decided to reinstall Wine (now version 1.3.8 ), to configure it as instructed by the guide, and than to install again the windows application, Birthday Reminder.
At present the application doesn't

Testing for randomness
Dear all,
Is there a test in R for the randomness of a sequence of observations (e.g.
to test the random number generator)? Specifically I am looking for autocorrelations
which are not necessarily linear in nature, which the acf function does
not seem to be flexible enough to detect as it tests for linear autocorrelation.
Thanks in advance,
Paul.

birthday problem (factorial limit)
Hi,
I tried to calculate the formula for the birthday problem
(the probability that at least two people out of a group of n people
share the same birthday)
But the factorial-function allows me only to calculate factorials up
to 170.
So is there a way to push that limit?
to solve this formula:
(factorial(365) / factorial((365-23))) / (365^23)
(n=23)

Rails, Postgres and the Date Field.
Hi guys,
I''m having problems with my app. First of all, I created a date_select
with the code:
<%= date_select(''contact'', ''birthday'', :order => [''day'',''month'',''year'']) %>
In the contacts table, I create a date field:
birthday DATE
When I save the values goes wrong into the database.

Re: Error loading mfc42.dll - failed (error c000007b)
:) Hi experts, hi dimesio
Few days ago Wine/Birthday Reminders stopped to run. I suppose that it is a consequence of an automatic updating of Ubuntu and I ask an advice on the best way to solve the issue.
Consider that:
if I run the application clicking on it, as usual, I see the system working and stopping after tens of seconds,
If I run the application by console, this is the code that I get

mv to /tmp = baby's birthday jpg's lost.
Hello all,
Yesterday I moved using the mv command in Redhat 7.2 ext3 file system to
move to /tmp my /mnt/win98/"My Pictures" directory to tmp. The command
executed normally, and I actually verified that the subdir was created
in /tmp and the files were there in /tmp/"My Pictures"
I was doing this to temporarily free space on my vfat windows 98

testing randomness of random number generators with student t-test?
Hi, subject more or less says it all.
I freely admit to not having bothered to find some of the online papers
about method of testing the quality of random number generators -- but
in an idle moment I wondered what to expect from something like the
following:
randa<-runif(1000)
randb<-runif(1000)
t.test(randa,randb)$p.value
var.test(randa,randb)$p.value

Wichmann-Hill Random Number Generator and the Birthday Problem
Dear all,
Recently I am generating large random samples (10M) and any duplicated
numbers are not desired.
We tried several RNGs in R and found Wichmann-Hill did not produce
duplications.
The duplication problem is the interesting birthday problem. If there are
M possible numbers, randomly draw N numbers from them,
the average number of dupilcations D = N(N-1)/2/M.

Form.serialize problem

Recursive Computation in R
Hi there,
I have written a function to calculate factorials as follows:
fact <- function(x) {
recurse <- x > 1
x[!recurse] <- 1
if( any(recurse) ) {
y <- x[recurse]
x[recurse] <- y * fact( y - 1 )
}
x
}
I want to be able to do the famous birthday problem, which will involve
the computation of 365!, however it shall get cancelled

Help with multiple subnets
I have two subnets in may LAN 192.168.0.0/24 and
192.168.1.0/24. Both subnets go out to the Internet
through a Linux box acting as a gateway, so the
gateway has one interface in each subnet (192.168.1.1
and 192.168.0.1). In both subnets I have Windows and
Linux machines and I want to configure SMB networking
using a workgroup (not a domain), so one workgroup for
more than one subnet.

Sound with Wine
Hello NG,
I am using Wine 20011108 (Debian Woody) and the most important programs are
running fine with it. I configured Wine with the winesetup-tool.
In general sound is running (e.g. with Winamp). And of course, sound runs
with Linux (KDE). But some programs seems to have some probems. I am
running a birthday reminder, which gives an notification sound in case of a
birthday. But this does

proposed pbirthday fix
Recent news articles concerning an article from The Lancet with fabricated
data indicate
that in the sample containing some 900 or so patients, more than 200 had
the same
birthday. I was curious and tried out the p and q birthday functions but
pbirthday
could not handle 250 coincidences with n = 1000. The calculation of upper

Happy Birthday portable OpenSSH!
It was one year ago today that I released a patch to get OpenSSH
compiling on Linux. I had no idea just how much trouble releasing that
patch would get me into :)
Within days I was inundated with patches, improvements and portability
enhancements - contributions which have made portable OpenSSH the
success it is today.
So allow me to thank the current developers and all of you who have

machine account locations
OK I'm confused.
Can machines be in ou=Computers,dc=somewhere,dc=net ?
Every thing works fine if I configure so that machine accounts are created under
ou=Users. If configured for machines to be in ou=Computers, I can't add a new
machine. Error returned is "The user name could not be found." This is from the w2k
machine itself.
The release notes for 3.0.11 seem to say adding
