Re: [Rails] Create animated gif from images in DB ...

If you want to go onto the animated gif direction, i believe the only option you have is to look at ImageMagick and RMagick, but this is not trivial stuff. On the other side, Javascript and modern browsers (like Safari and FireFox) can help you with something like : a=0; setInterval(function(){

Re: [Rails] Re: Find distinct values in an array of database results

If I may jump in, I'm interested in understanding why you would do this kind of database job with Ruby vs. an extra SQL query. I had the feeling that it would be wiser (and would execute faster) to delegate the job to the database engine But I'm kind of amateur. Thanks to anyone who is willing

[Rails] Problem with require 'RMagick'

First, pardon me if this is not the right forum. I'm banging my head on the wall for a day now with a RMagick installation issue. I installed ImageMagick and RMagick both from source. They compiled with problems. (I had some issues with fonts, but that's over) In the ruby console, this works :
