similar to: Running Linux Command Through Ruby

Hi all, Slightly OT, but is there any way to run command-line programs through Ruby? I have a rails web application that performs some database work. After a certain action is performed, the rails app should then call a java program that performs additional work to our mainframe. This is under Win 2003 Server. Any ideas?

Hi I got some strange issues on my samba4.0.1 install yesterday. It happened a while after updating my xubuntu server 13.04 not 13.10. Everything seems to be working fine except shares. Kerberos authentication seem to function properly, also DNS works fine but shares seem semi-broken. I can't mount any shares on my Windows box, including netlogon, profiles. I have one share that is

Hello... I am trying to execute a php script from within rails.

I'm having trouble getting an AGI exec command to spawn app_disa. The script executes properly, but does not spawn DISA. The CLI gives no helpful clues. Am I doing the exec incorrectly? I want to have a way to authenticate callers to the extension by Caller ID... if their caller ID is in my database and set to active, they can call out. [like a calling card but auth'd by CID instead

Hi all, I've just written a small enhancement to SimplifyPHINode. The idea is the following: If we have this: a = phi(X, X, undef, undef, X, undef) X = select cond, sth, a or this: a = phi(X, X, undef, undef, X, undef) X = select cond, a, sth we can replace the phi by 'a' and the select by 'sth'. Why does this work? Well, in those cases where control-flow happens to

Hi, My english isn't brilliant and my problem is very difficult to describe but I try ;) My first question is: May I write loop "for" like this or similar - for (i in sth : sth[length(sth)], k in sth_else : length(sth_else) ) - I'd like to have two independent conditions in the same loop "for". My secound question depend on program below. I'd like to write every

Hi Roland, > If we have this: > > a = phi(X, X, undef, undef, X, undef) such a phi should already be replaced by X if X dominates this basic block. Is this not the case? Or does each X here not necessary represent the same value? Ciao, Duncan. > X = select cond, sth, a > > or this: > > a = phi(X, X, undef, undef, X, undef) > X = select cond, a, sth > > we can

Is there a way to do this with llvm-lit, i.e., use the equivalent of backticks? foo takes a single argument, but doesn't read from stdin. // RUN foo some_arg > %t; FileCheck %s < %t // RUN foo `cat %t` | FileCheck --check-prefix=INVERSE // CHECK: {{^[0-9]+$}} // INVERSE: some_arg thanks... don -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I noticed that, when working with R on a command line, I cannot enter anything into the command line which is longer than 1023 characters. If I input sth longer, it'l be just cut off at this lenght, and a "+" will be presented to me on the command line. It's not as bad since I can copy'n'paste commands longer than this with newline characters in between onto the

Hi all, My app is going to count sth based on poll id in the url. The url looks like: http://address.com?id=dwNKiItvcyrQ5sycnIhmJablDfXsc9tshaGIVyNIei7.e7&some_other_parameters In a controller, I''ve created a hash where the keys are the ids: @codes = { ''dwNKiItvcyrQ5sycnIhmJablDfXsc9tshaGIVyNIei7.e7'' => {:partner_id => 0,

Hello, I need to generate a unique ID, so far I''ve unit tested this under 100000 iterations and it seems to work : now.to_i.to_s + ''-'' + now.usec.to_s + ''-'' + rand(1000).to_s Is there a better way ? Thanks Notes : 1) without usec, few percents of generated values are not uniques 2) the id generated is a string so the presence of

Hi All. I would like to create a model, database, and controller (if possible) from a webapp. Each model and controller will each have 4 methods, and the database will always have the same number of fields. I will probably create the database through create_table or a direct SQL command. My question is this - is there a method that I can call to create the model and controllers? Would it
