Hi, I want to be able to run shell commands from Rails. I''m on the Windows platform. Would the code below work on Windows if IO.popen is called? If not, how would I run a shell command in Windows in order to run the ffmpeg program? ** *-----------------------------------* *def encodeVideo opts, stream IO.popen("ffmpeg #{opts}", ''w''){ |io| io.puts stream}

I use ControlMaster auto (along with ControlPath) in my ssh config and find it very handy. I have noticed an annoying behavior, though: it seems that if there is no existing master connection and ssh creates a new one, the master connection process that is started has its stderr left open. This has manifested itself in two ways so far: (1) When using ssh day-to-day, I may be doing some work and

Hi, I've spent some part of the last week on trying to figure out whether dovecot LDA meets our requirements for a new mail server infrastructure (the IMAP and POP servers, as well as the SASL backend certainly do; thanks a lot!). The one thing that's holding me back is that we need per-user integration of SpamAssassin and some other, custom content filters, all of which are implemented

I have been using rails on Debian Sarge since May of last year. I initially gem installed rails as root and since then I have been gem updating the installation. I have had no trouble with the installation or development. Now feel that I''d like to use svn to get edgerails to be able to use nifty features such as RJS. Some of the threads on the subject talk about svn:externals in the

Since my previous question didn''t get much attention, I thought I''d make the subject more expressive. I didn''t realize the list had this much traffic. Is anyone using system or "backquote" to run commands in Rails? These work fine in webrick, but both return nil when running in Apache FCGI. In CGI mode, system seems to work, but backquote doesn''t.

Dear Rails, I would like to pose a question to Mike Hanson (June 20th thread)... I am a Technical Recruiter, and I am having a difficult time understanding the difference between building attribute-driven databases vs. building data-driven databases. Can you help me understand how these two differ. I am having a difficult time speaking to candidates about their experience with

Is there some way to tail -f a file and print whatever tail -f gets to the browser on the client side. I''m thinking periodically call remote can do it. Is there some shortcut method, or does one have to store the cursor line that they read up to from the file last time, and then start reading again from the new cursor on the next periodically call remote. thanks -- Posted via

Hi, I have a strange problem viewing data in real time. I wonder can anyone help? I run tail -f on a file which is served by a windows 2000 machine. I start a simple program running on windows 2000 which writes numbered lines of text to this file. I notice that tail -f is missing some of the lines. If I edit the file afterwards the data is there it's just that tail seems to miss bits of it

I''m looking for a solution where I could load and render pages from one Rails application within another. I''m looking through the Rails code right now to see if this would even be remotely possible. Does anyone have any ideas? I know the obvious answer would be to proxy the app via Net::HTTP, but this is undesirable because: - I don''t always want to depend on having
