Merb was originally created by Ezra Zygmuntowicz to avoid some Rails upload issues.

This is one of the things that Merb was written for. Rails doesn‘t allow multiple concurrent file uploads at once without blocking an entire rails backend for each file upload. Merb allows multiple file uploads at once.

I’ve built ‘multiple’ file uploaders for Rails sites but they always involved some slight of hand, the files appeared to be uploading all at once but they where actually queued up by Flex then handled one by one by the app (which also had the unhappy side effect of blocking any other requests to that process). I’ve been wanting to try out Adobe AIR’s file system drag and drop for a while so this is a two-fer example. You’ll need the beta version of Flex Builder 3 or the Flex 3 SDK beta if you don’t mind getting down with the command line.

In a hurry? Here’s one I made earlier (flex source in ‘dist/app/fx‘).

Taking Merb to Production

For small applications, a database can be overkill for storing your data in a consistent and
organized manner. Therefore, Stone was built to provide plug-and-play data persistence for
any application or framework. It is fast, and it is easy… therefore it is good.

You can check out an application that uses Merb+Stone here.

The source for that blog is here.

Spent a while today getting up and running with Merb, the minimalist modular alternative Ruby framework from Ezra and the good people at Engine Yard. Merb has been in a bit of chaos these recent months as it's gone through a major reworking to acheive a whole new level of performance as well as honest-to-goodness modularity, including choosing your own ORM and templating system. I've been watching Merb's development for some time waiting for it to get to a level of stability that looked safe enough to dive in; their most recent release, 0.9.2, combined with pressing needs in a few exciting new Grabb.it features, made today the day.

My first day with Merb has been mostly great, but the one thing I found really sorely missing was a tutorial on how to get started. In all fairness, the Merb team promises left and right that copious documentation will be coming as they settle down to 1.0. In the meantime, I thought I'd pitch in for any brave early adopters out there with this Guide to Installing Merb and ActiveRecord.

Thin is a Ruby web server that glues together 3 of the best Ruby libraries in web history:

• the Mongrel parser, the root of Mongrel speed and security
• Event Machine, a network I/O library with extremely high scalability, performance and stability
• Rack, a minimal interface between webservers and Ruby frameworks

Which makes it, with all humility, the most secure, stable, fast and extensible Ruby web server
bundled in an easy to use gem for your own pleasure.
