• Error processing Spree sample images - file not recognized by identify command in paperclip geometry.rb:29

  - by purpletonic

  I'm getting an error when I run the Spree sample data. It occurs when Spree tries to load in the product data, specifically the product images. Here's the error I'm getting: * Execute db:load_file loading ruby <GEM DIR>/sample/lib/tasks/../../db/sample/spree/products.rb -- Processing image: ror_tote.jpeg rake aborted! /var/folders/91/63kgbtds2czgp0skw3f8190r0000gn/T/ror_tote.jpeg20121007-21549-2rktq1 is not recognized by the 'identify' command. <GEM DIR>/paperclip-2.7.1/lib/paperclip/geometry.rb:31:in `from_file' <GEM DIR>/spree/core/app/models/spree/image.rb:35:in `find_dimensions' I've made sure ImageMagick is installed correctly, as previously I was having problems with it. Here's the output I'm getting when running the identify command directly. $ identify Version: ImageMagick 6.7.7-6 2012-10-06 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2012 ImageMagick Studio LLC Features: OpenCL ... other usage info omitted ... I also used pry with the pry-debugger and put a breakpoint in geometry.rb inside of Paperclip. Here's what that section of geometry.rb looks like: # Uses ImageMagick to determing the dimensions of a file, passed in as either a # File or path. # NOTE: (race cond) Do not reassign the 'file' variable inside this method as it is likely to be # a Tempfile object, which would be eligible for file deletion when no longer referenced. def self.from_file file file_path = file.respond_to?(:path) ? file.path : file raise(Errors::NotIdentifiedByImageMagickError.new("Cannot find the geometry of a file with a blank name")) if file_path.blank? geometry = begin silence_stream(STDERR) do binding.pry Paperclip.run("identify", "-format %wx%h :file", :file => "#{file_path}[0]") end rescue Cocaine::ExitStatusError "" rescue Cocaine::CommandNotFoundError => e raise Errors::CommandNotFoundError.new("Could not run the `identify` command. Please install ImageMagick.") end parse(geometry) || raise(Errors::NotIdentifiedByImageMagickError.new("#{file_path} is not recognized by the 'identify' command.")) end At the point of my binding.pry statement, the file_path variable is set to the following: file_path => "/var/folders/91/63kgbtds2czgp0skw3f8190r0000gn/T/ror_tote.jpeg20121007-22732-1ctl1g1" I've also double checked that this exists, by opening my finder in this directory, and opened it with preview app; and also that the program can run identify by running %x{identify} in pry, and I receive the same version Version: ImageMagick 6.7.7-6 2012-10-06 Q16 as before. Removing the additional digits (is this a timestamp?) after the file extension and running the Paperclip.run command manually in Pry gives me a different error: Cocaine::ExitStatusError: Command 'identify -format %wx%h :file' returned 1. Expected 0 I've also tried manually updating the Paperclip gem in Spree to 3.0.2 and still get the same error. So, I'm not really sure what else to try. Is there still something incorrect with my ImageMagick setup?

• WCF .Net 4.0 is treating WebProtocolException as an unhandled exception

  - by Benjii

  Im trying to build an API using WCF and .Net 4, however when I throw the WebProtocolException, it is not displaying a nice error message like it should, instead it is treating it like an unhandled exception. I am using the WebServiceHost2Factory. Has anyone else used WebProtocolException with .net 4? An example of my call is below throw new WebProtocolException(System.Net.HttpStatusCode.BadRequest, "The DateFrom parameter is invalid", new Error() { Code = 6002, Message = "Please ensure your dates are in the following format: yyyy/MM/dd hh:mm:ss" }, null, null);

• How to implement " char * ftoa(float num) " without sprintf() library function in C, C++ and JAVA

  - by SIVA

  Today I appeared for an interview, and the question was writing my own "char * ftoa(float num) " in C, C++ and Java. Yes, I know float numbers follow IEEE standard while allocating their memory, but I don't know float to char conversion by using Mantissa and Exponent in C. I don't have any idea to solve the above problem in C++ and JAVA. I/P to the ftoa(): 1.23 O/P from the ftoa(): 1.23 (char format). Thanks in advance ...

• Programmatically convert a video to FLV

  - by Raibaz

  Hi all, i am currently working on a web application that needs to accept video uploaded by users in any format (.avi, .mov, etc.) and convert them to flv for playing in a flash-based player. Since the site is OpenCms-based, the best solution would be a ready-made plugin for OpenCms that allowed to upload and play videos doing the transcode operation in background, but just a set of Java classes to do the transcode would be great and then i could make the uploading form and playback part on my own.

• Possiblity of loading/executing ELF files on OSX

  - by Daniel Brotherston

  I'm just curious as to the possibility of loading and executing elf files on OSX. I know the standard executable format is MACHO, but NASM is unable to generate debug information for MACHO objects (and I am required to use NASM). I imagine its a long shot, but I don't suppose I can use ELF files. I can build them with NASM, but I can't seem to even link them with LD.
