  - by Michael Waxman

  It's much harder than you'd think: http://wiki.developers.facebook.com/index.php/Photos.upload The tricky part is how to create the MIME multi-part message in Rails, which Facebook requires. I'm also using a Ruby Facebook API gem (mini_fb) which signs my other requests, and in addition to having no idea how to set up the MIME multi-part, even if I did I'm not sure how to add in the required signature values with the gem. Please help!

• Fast ruby http library for large XML downloads

  - by Vlad Zloteanu

  I am consuming various XML-over-HTTP web services returning large XML files ( 2MB). What would be the fastest ruby http library to reduce the 'downloading' time? Required features: both GET and POST requests gzip/deflate downloads (Accept-Encoding: deflate, gzip) - very important I am thinking between: open-uri Net::HTTP curb but you can also come with other suggestions. P.S. To parse the response, I am using a pull parser from Nokogiri, so I don't need an integrated solution like rest-client or hpricot.

• Do I need to know Ruby in order to learn Ruby on Rails?

  - by boutta

  I've read several other questions about material in order to learn RoR. But my question is can I start learning RoR without Ruby? It's clear that the other way around is better, but I would rather try this way if it makes sense (somehow). Or learn both in parallel...

• Ruby is already using the class name of my model

  - by Octopus Inc

  I'm making a forum application with various levels of authorization, one of which is a Monitor.

• Ruby BigDecimal sanity check (floating point newb)

  - by Andy

  Hello, Hoping to get some feedback from someone more experienced here. I haven't dealt with the dreaded floating-point calculation before... Is my understanding correct that with Ruby BigDecimal types (even with varying precision and scale lengths) should calculate accurately or should I anticipate floating point shenanigans? All my values within a Rails application are BigDecimal type and I'm seeing some errors (they do have different decimal lengths), hoping it's just my methods and not my object types... Thanks!

Something like exec "lib/daemons/mydaemon_ctl start"? Thanks!
