Get a copy of a matrix only for TRUE entries of a matching size boolean matrix?
...] "A" "B"
[2,] "C" "D"
> mat_bools <- matrix(data=c(FALSE, TRUE, TRUE, FALSE), ncol=2, byrow=TRUE)
> mat_bools
[,1] [,2]
[1,] FALSE TRUE
[2,] TRUE FALSE
*Reminder:* The following is only an example ; the solution might look very
different.
some_command(mat_letters, mat_bools, false=empty)
[,1] [,2]
[1,] "" "B"
[2,] "C" ""
some_command(mat_letters, mat_bools, false=na)
[,1] [,2]
[1,] NA "B"
[2,] "C" NA
Thank you kindly

Lazy evaluation of exec clause in ssh Match statement
Hello,
At present, if a ssh Match block contains an exec clause, the specified
command is executed regardless of whether any preceding clauses are
true. Thus,
Match host !*.* exec "some_command %h"
...
would always execute some_command regardless of whether the host matches
the preceding pattern. That seems undesirable, particularly as the
user-specified command may do name lookups or other operations that may
introduce delays.
Using a lazy approach, where the command is only exe...

[cucumber] Where does STDOUT go?
If one invokes a Ruby script from a cucumber step definition and that
script contains "puts" statements then where does the output go? I have
a script that when run from the command line displays "puts" output in
the terminal session, but when run from a cucumber step definition
produces no console output. It does however produce the expected output
file in either case.

openssh 2.9p1: data loss when stdout sent to a pipe
We recently tried upgrading openssh from 2.5.2p2 to 2.9p1
and discovered that it no longer worked to feed the output from a remote
command into a pipe, unless the output was short and the pipe was very
fast at processing its input.
Example 1: ssh remote_machine some_command | less
(where "some_command" generates a lot of output) now fails after
the first screenful, with a "Write failed flushing stdout buffer" message.
Example 2: ssh remote_machine 'yes | head -2000' | (sleep 3 ; wc -l)
With openssh 2.5.2p2 this correctly returns "...

Cron, when used with RoR, has the following shortcomings:
* Significant startup resources required
* Lots of RAM to run simultaneous processes
* Hard to start/stop/affect the background processes from within Rails.
RailsCron addresses these shortcomings by using one RoR instance with

debugging package
I am trying to debug a package to submit it to CRAN and am getting a bunch
of error messages. Most of the errors are because of the Rd files which
were automatically populated by the package.skeleton function. I find the
section on documentation to be pretty confusion in the R Extensions manual.
Any help on getting these errors fixed would be hugely appreciated. Thanks.

sudo add user script
Hello list,
I took another stab at finding a way to add a sudo user remotely and it
gets you most of the way there. If you execute the script as root it works
beautifully and does just what you want. Which is add the user to the
group and gives that user group rights to certain commands.
But if you execute it as a user who only has sudo access to the
/etc/sudoers file it errors out.
