Translated (language-aware) routes in Rails application
Hi,
I''d like to have translated languate-aware routes in my application,
like:
/projects/5/permissions => locale "PL"
/projekty/5/pozwolenia => locale "PL"
Is there any way to achieve it with RESTful routes? I have done it
manually with named routes, but it''s overwhelming with over 300
routes :D Also tried namespace (yeah, didn''t work) and

[LLVMdev] [NVPTX] llc -march=nvptx64 -mcpu=sm_20 generates invalid zero align for device function params
Hello,
FYI, this is a bug http://llvm.org/bugs/show_bug.cgi?id=13324
When compiling the following code for sm_20, func params are by some reason
given with .align 0, which is invalid. Problem does not occur if compiled
for sm_10.

Group by in R
Hi,
I have the following table data:
f1, f2, f3, f4.
I want to compute the counts of unique combinations of f1-f4. In SQL I would
just write:
SELECT COUNT(*) FROM <table> GROUP BY f1, f2, ..,f4.
How to do this in R?
Thanks,
Nick

searching with chinese chars
Hi all,
maybe not a Ferret question, but I assume here might have came across
that already.
I wrote a simple CGI app that adds docs into a Ferret index. The idea
is testing asian languages input and searching.
The script that does the input seems to be OK. As David mentioned in a
question I made a little while ago, Ferret''s index is agnostic, in the
sense that you can store anything in

Possible Improvement of the R code
Dear all,
In the following code, I was trying to compute each row of the "param"
iteratively based
on the first row.
This likely is not the best way. Can anyone suggest a simpler way to
improve the code.
Thanks a lot!

How should I denormalise a data frame list of lists column?
Hi,
I have a data frame where one column is a list of lists. I would like to
subset the data frame based on membership of the lists in that column and be
able to 'denormalise' the data frame so that a row is duplicated for each of
its list elements. Example code follows:
# The data is read in in this form with the c2 list values in single strings
which I then split to give lists:

Not all files synched - hard link problems???
I am sorry if this has been covered before: I have done a couple of
futile searches in the bug reporting system and is there any way to
search the archive?
I am having a strange symptom: I am synching directories (that have
very long file names, by the time the full path is specified) and a lot
of hard links. It seems that the directory is being copied piecemeal -

Plotting a segmented function
This might be a trivial question, but I would appreciate if anybody
could suggest an elegant way of plotting a function such as the
following (a simple distribution function):
F(x) = 0 if x<=0
=(x^2)/2 if 0<x<=1
=2x-((x^2)/2)-1 if 1<x<=2
=1 if x>2
This is just an example. In this case it is a continuous function. But
how to do it in general in an elegant way.

updating elements of a vector sequentially - is there a faster way?
I would like to know whether there is a faster way to do the below
operation (updating vec1).
My objective is to update the elements of a vector (vec1), where a
particular element i is dependent on the previous one. I need to do this on
vectors that are 1 million or longer and need to repeat that process
several hundred times. The for loop works but is slow. If there is a faster
way, please let

Second largest element from each matrix row
Hi,
I need to extract the second largest element from each row of a
matrix. Below is my solution, but I think there should be a more efficient
way to accomplish the same, or not?
set.seed(1)
a <- matrix(rnorm(9), 3 ,3)
sec.large <- as.vector(apply(a, 1, order, decreasing=T)[2,])
ans <- sapply(1:length(sec.large), function(i) a[i, sec.large[i]])

I want to set entries in a data frame of zeros ('starts' in the code below) to 1 at certain points and the points have been randomly generated and stored in a separate data.frame ('sl'), which has the same number of columns.
An example of the procedure is as follows:

Conditionally adding a constant
I am trying to add a constant to the previous value of a variable based on
certain conditions. Maybe there is a simple way to do this that I am missing
completely. I have given an example below:
df <- data.frame(x = c(1,2,3,4,5), y = c(10,20,30,NA,NA))
> df
x y
1 1 10
2 2 20
3 3 30
4 4 NA
5 5 NA
I want to add 2 to the previous value of y, if x exceeds 3 (also will have
to handle NAs in
