I have an ActiveRecord subclass that needs to generate a random (hard to guess) token for each record in its corresponding table. Currently I''m doing something like this: def before_create self[''token''] = random_value while self.class.find_by_token(self[''token'']) self[''token''] = random_value

Hi Everyone, I have been trying to read some Arrayvision files( 2 channel cDNA) and am having some problem. My code is : setwd('C:/work/data/limma/ndd1'); files <- c('ndd1_1.txt','ndd1_2.txt','ndd1_3.txt'); RG=read.maimages(files,"arrayvision",sep="\t"); #Normalisation MA=normalizeWithinArrays(RG); #plotPrintTipLoess(MA); #Fit Linear

Having implemented a GC for HLVM, I am now turning my attention to implementing a GC that supports parallelism. To do this, I would like to use atomic instructions as well as mutexes. What is the status of LLVM's atomic instrinsics (e.g. CAS)? Is anyone using them in real projects? I realised that an obvious test would be to compile some simple example programs with llvm-g++ instead of

Is there a method to return a hash of the route configuration based on a path? For example: magic_method(''/my_controller/my_action/my_id'') => {:controller => ''my_controller'', :action => ''my_action'', :id => ''my_id''} Thanks!

Hello, I am author of a Morse code training software written in Perl at http://starling.ws/morse Currently I output to *.wav and, if on Unix, convert to *.ogg. And that's okay for a trainer. But I have desire to upgrade the project to a real-time communication tool...or at least a Morse code audio mail routine. And I should like to avoid *.wav. I'd like some means of writing a pure

Hi, We are using pxelinux at my company to test our product. And there are limitations that we have hit in the past w.r.t. the max length of a path, or the max length of a module name (in mboot.c / mboot.c32). We've used workarounds in the past, and reorganized the directory structure, but we face that problem again. Out of the 128 / FILENAME_MAX chars that can be used, 110 - 120 go to the

I''ve scheduled cron jobs etc before, but I''m curious as to how to layout a worker properly. Here''s a basic example of what one of my workers looks like: class FooWorker < BackgrounDRb::MetaWorker set_worker_name :foo_worker def create(args = nil) logger.info("Starting test: #{Time.now.strftime("%T")}") run_test logger.info("Finished test:

Hello, i need to have some jobs scheduled in the background and executed at specific times. I wanted to make a worker who does that - and it works a little bit - but i had an enlightment... why not make bgdrb itself play that role? i mean, the MiddleMan has already everything needed! a timer thread, currently used only for deleting old workers and the workers itself. since im not familiar with

Hello all, I''ve got the problem about the following simple application using autostart and repeat_every.

In production mode, I keep getting this error the 2nd time it loads a page with a serialized attribute: ActiveRecord::SerializationTypeMismatch (answers_container was supposed to be a Array, but was a NilClass): /vendor/rails/activerecord/lib/active_record/base.rb:1964:in `unserialize_attribute'' In development, it works fine. In fact, if I set to false config.cache_classes in

Hi, After a quick read of the Theora spec, I became curious about the possibility of fast quality reduction of Theora videos. The idea is to decode through the Huffman and reverse prediction steps, and then to truncate the coefficients and reencode. My questions are: * Is this a reasonable way to reduce the quality and bitrate of a stream? Will it be comparable in quality to a complete

Hi guys, In my Rails app, I have three models: A, B and C, with the following relationships: - B hasMany C - C belongsTo B I would like A to "has_one" instance of B+C. By that I mean A needs to be linked to a specific instance of B AND a specific instance of C. My first guess would be to create a fourth object, say B_plus_C that would: - belongs to B - belongs to C - belongs to A Is

Hi all I am working on a heavy engineering project. And the requirement is that I needto do a lot of process before I store the data to the db. Now the question is that I want to do the process that I am doing but I want to do it in the background. What I actually mean to say is that..I just want the user to get a msg that Records Saved. But in real I want the process to go on in background.

[Follow-ups set to gmane.linux.centos.general] My wife had been running CentOS 6.4 almost since its inception; then her PC broke down. We got a PC from System76, and Ubuntu turned out utterly unsuitable for us, as expected -- as bad for us as Gnome3. (I had previously bought a System76 net book (starling iirc), and immediately installed the then current Fedora; all has been
