is there a way that, our application can understand wheteher the session id sent from the browser is forged or created by rails? I understand that if the attacker guesses session id, theres nothing we can do about it; but can we understand if he/she is trying to guess by creating random session ids. _______________________________________________ Rails mailing list

Hi, I'm developing an experiment with logistic regression. I've come across the lrm function in the Design library. While I understand and can use the basic functionality, there are a ton of options that go beyond my knowledge. I've carefully read the help page for lrm, but don't understand many of the arguments and optional return values. (penalty, penalty.matrix,

I think he might be concerned with audio quality, and doesn't quite understand what "lossless" really means!

Hi all, I would greatly appreciate some help understanding how R references arrays, matrices, lists, and objects using [[]] and []. I have read the R guides and several tutorials but I am not the fastest kid on the block so I am still having difficulty understanding this. For examples the following code produces a 5 element list of 2X5 random numbers that I then convert to a 2X5X5 matrix.

I am trying to understand the function acf stats:::acf shows me the function I am having trouble understanding the usage "$acf" in the following acf <- array(.C(R_acf, as.double(x), as.integer(sampleT), as.integer(nser), as.integer(lag.max), as.integer(type == "correlation"), acf = double((lag.max + 1L) * nser * nser), NAOK =

Dear All, I'm currently working on a project with the purpose of remotely executing R code, which requires me to have to work with the code of R itself. I've searched the Internet for good information that will help me understand how R is implemented but what I've got so far isn't detailed enough. I've looked specifically at CRAN's manuals on the official website but

Maybe this should apply to Ruby forums directly, but I''ll try here. I understand the concept of classes and subclasses thanks to the excellent "Programming Ruby - The Pragmatic Programmer''s Guide". However, I don''t understand what :: signify in terms of inheritance, parent and child in e.g. ActionController::Base -- Posted via http://www.ruby-forum.com/.

Hi friendly LLVM Devs, I'm trying to understand the technical details of tail call optimization, but unfortunately I hit some issues that I couldn't figure out myself. So I tried the following two really simple functions: > extern void g(int*); > void f1() { > int x; > g(&x); > } > void f2(int* x) { > g(x); > } > It turns out that 'f1'

Rick, Mark asked "why" you want the least amount of compression. I think we still do not understand your goals. If you can give us a hint at what you're trying to accomplish in your search for the least amount of compression, that might help us find the right answer.

I got an output. But I changed it. But still the same problem. But is there a place with more info about this. From my understanding, am I linking windows rights with the unix rights. But I don?t really understand what I am doing. I just copy the winbind settings, and don?t really bother. But maybe when I understand what I am doing, I can fix the problem myself. Btw the problem is, to my

Hi, I am new to LLVM. I am experimenting with a toy backend. I don't understand "LowerFormalArguments didn't return a valid chain" in SelectionDAGBuilder.cpp file. What is the interface here? What does it mean by returning a Chain? Thanks Jen. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi Duncan, Is it correct that opt does not understand codegen passes, but llc understands both analysis/transformation and codegen passes? I would like to modify bugpoint to work on this end.

Dear R helpers, I am trying to understand how to use the independence_test function in the coin package. I think I suffer from a misunderstanding about what the package does. Either that or I do not understand how to use it properly. Specifically, I cannot understand if I can test independence of arbitrary statistics. Take the following example: set.seed(10) d <- data.frame(y = c(rnorm(10,

Dear all, I am struggling to understand the johansen test procedure in the context of co-integration in time series. Yes I understand that this forum is not directly statistics related but still I am posting here hoping that I would get som help. The error correction representation of a VAR[p] model can be written as: Delta y[t] = A[0]*y[t-1] + A[1]*Delta y[t-1] +..............

Apparently the way to deal with this error message is to set R_CStackLimit = (uintptr_t)-1 I tried typing this in the R console, but it says Error: object "R_CStackLimit" not found. So where do I type it? In one of the initialization files that R uses when it starts up? I can't find the answer anywhere. Please note that I don't understand words like "DLL" or

Hi, I am trying to implement Higham's algorithm for correcting a non positive definite covariance matrix. I found this code in R: http://projects.cs.kent.ac.uk/projects/cxxr/trac/browser/trunk/src/library/Recommended/Matrix/R/nearPD.R?rev=637 I managed to understand most of it, the only line I really don't understand is this one: X <- tcrossprod(Q * rep(d[p], each=nrow(Q)), Q) This

Hi, Just trying to consolidate my knowledge of Dovecot and I want to understand various things rather than just key out lines of config in dovecot.conf with the hope of it working. What I wanted to clarify is my understanding the "socket listen" section of the config file. From my limited understanding, this section details how other processes can access the userdb defined in

Ram, Please read and understand the GetElementPtr FAQ available here: http://llvm.org/docs/GetElementPtr.html That will help you understand how it works.
