Building R package: “Found 'rand', possibly from 'rand' (C)” NOTE when checking package
I am building a package that makes a simple visualization. A part of the code is in C++, and utilizes the functions srand() and rand() for purposes not related to statistics (introducing random noise in the visualization). The package compiles without problems on my workstation(s), but when I submitted it to the winbuilder service, I got the following weird message: * checking compiled code ...

[LLVMdev] Use rand_r() instead of non-reentrant thread-unsafe rand() in GetRandomNumber()
Dear all, In our LLVM-based compiler pipeline a major part of code generation is taken into application runtime. One side-effect of this organization is a need to be very careful about using code that might diverge application state. And we found that simple generation of temporary files over LLVM APIs introduces random noise into the program result. There reason is that LLVM's

[LLVMdev] Use rand_r() instead of non-reentrant thread-unsafe rand() in GetRandomNumber()
If we're keeping the state locally now, perhaps we should store it in a per-thread variable. I know rand() isn't thread safe to begin with, but it seems like rand_r() can be since it should keep no external state.

4-stable and C rand()?
Hi everyone, sorry if this has been answered before - I caught a whiff of a discussion about c's rand() function in a mailing list archive, but couldn't find a definitive answer. I'm trying to do a simple CS project on my machine where I generate two sets of values in parallel using rand() and am running into infinite loops of values, and couldn't figure out why, so I wrote a test

[LLVMdev] Use rand_r() instead of non-reentrant thread-unsafe rand() in GetRandomNumber()
Agreed, done. One thing I'm not sure about is this statement in docs: POSIX.1-2008 marks *rand_r*() as obsolete. - And... what is the replacement? 2012/12/1 Justin Holewinski <justin.holewinski at gmail.com> > If we're keeping the state locally now, perhaps we should store it in a > per-thread variable.

Cannot run OpenSSH 3.1p1 on Solaris 8, Irix 6.5.14, Irix 6.5.4, SunOS 4.1.3_U1 - ssh-rand-helper child produced insufficient data
I have successfully compiled OpenSSH 3.1p1 for the following systems: Solaris 8 Solaris 7 Irix 6.5.14 Irix 6.5.4 SunOS 4.1.3_U1 Unfortunately, the new sshd is not working on any of the above systems with the exception of Solaris 7. (I then put the Solaris 7 executables on Solaris 8, and they worked there too.) This is the error I'm getting: $ /usr/etc/sshd -D -d -d -d debug3: Seeing PRNG

path to find ssh-rand-helper
Before I actually implement the small changes needed to allow the location of ssh-rand-helper to be specified in the config file, I'd like to check that in doing so I won't be opening up a huge security hole. My brief reading of the code suggests that in entropy.c:seed_rng() the ssh-rand-helper is run as the original uid (for binaries which were setuid in the first place of course), so I

Clustering and Rand Index - VS-KM
Dear WizaRds, I have been trying to compute the adjusted Rand index as by Hubert/ Arabie, and could not correctly approach how to define a partition object as in my last request yesterday. With package fpc I try to work around the problem, using my original data: mat <- matrix( c(6,7,8,2,3,4,12,14,14, 14,15,13,3,1,2,3,4,2, 15,3,10,5,11,7,13,6,1, 15,4,10,6,12,8,12,7,1), ncol=9, byrow=T )

ssh-rand-helper
Now that ssh-rand-helper has been segregated into a separate program, I'd like to revisit an old question about its entropy gathering. - would it be desirable to make it possible for ssh-rand-helper to fall back to external commands if PRNGD cannot be reached, instead of choosing one or the other at compile time? - When using PRNGD, the program gets 48 bytes of entropy from PRNGD,

Ruby fun with MegaMillions
I thought I would write a lottery number generator since I have not had any luck winning the big jackpot - http://megamillions.com/. So far, after over 1.2 million tries, I still have not hit all the numbers from yesterday: 2, 17, 22, 32, 51, 35 (last one is the mega ball). Fun little project that and I thought others would be interested. Let me know if you have a cleaner implementation in mind.
