My personal notes... http://www.ayresnarita.com I just found this nice plug-in for PhotoShop that enables you to save images in "ico" format. It makes dead ease to make favicon.ico, that little icon resting on the left side of your browser's address bar. <p><a href="http://feedads.g.doubleclick.net/~a/24YcxU8bB9NO5Li9EaM7y0Jp2IA/0/da"><img src="http://feedads.g.doubleclick.net/~a/24YcxU8bB9NO5Li9EaM7y0Jp2IA/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/24YcxU8bB9NO5Li9EaM7y0Jp2IA/1/da"><img src="http://feedads.g.doubleclick.net/~a/24YcxU8bB9NO5Li9EaM7y0Jp2IA/1/di" border="0" ismap="true"></img></a></p><img src="http://feeds.feedburner.com/~r/ayresnarita/~4/Ko-X3AfGEtk" height="1" width="1"/> 30 March, 2009 http://feedproxy.google.com/~r/ayresnarita/~3/Ko-X3AfGEtk/favicon_%22ico%22_format_on_photoshop http://www.ayresnarita.com/show_entry/favicon_%22ico%22_format_on_photoshop I assume everybody knows how to install ImageMagick usin MacPorts. MacPorts is a fantastic tool to easily install software in your mac, but sometimes the project you are working on requires the latest feature only available on the latest version of your software or library. Most of the times MacPorts will have it, but... you better know how to build your software from source just in case. <p><a href="http://feedads.g.doubleclick.net/~a/XBledv5YBZfycbioasOxhr70Yvc/0/da"><img src="http://feedads.g.doubleclick.net/~a/XBledv5YBZfycbioasOxhr70Yvc/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/XBledv5YBZfycbioasOxhr70Yvc/1/da"><img src="http://feedads.g.doubleclick.net/~a/XBledv5YBZfycbioasOxhr70Yvc/1/di" border="0" ismap="true"></img></a></p><img src="http://feeds.feedburner.com/~r/ayresnarita/~4/wDVtmdmW2mI" height="1" width="1"/> 21 March, 2009 http://feedproxy.google.com/~r/ayresnarita/~3/wDVtmdmW2mI/get_imagemagick_with_png_and_jpg_delegates_installed_on_mac_osx_leopard_without_using_macports http://www.ayresnarita.com/show_entry/get_imagemagick_with_png_and_jpg_delegates_installed_on_mac_osx_leopard_without_using_macports I assume that everybody already knows about "Paperclip" and also the "validates_attachment_content_type" method to validate the file type against the mine-type sent by the browser. The problem starts when your customer calls you saying that he/she is not able to upload his images, and an error "Image is not one of the allowed file types" pops every time he/she tries. <p><a href="http://feedads.g.doubleclick.net/~a/x25o6crOJQtBjEPN_axVRh02OII/0/da"><img src="http://feedads.g.doubleclick.net/~a/x25o6crOJQtBjEPN_axVRh02OII/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/x25o6crOJQtBjEPN_axVRh02OII/1/da"><img src="http://feedads.g.doubleclick.net/~a/x25o6crOJQtBjEPN_axVRh02OII/1/di" border="0" ismap="true"></img></a></p><img src="http://feeds.feedburner.com/~r/ayresnarita/~4/70YoRKyAatY" height="1" width="1"/> 12 March, 2009 http://feedproxy.google.com/~r/ayresnarita/~3/70YoRKyAatY/internet_explorer_error_validating_file_type,_when_uploading_images_using_paperclip_(_ie7,_ie6_mine-type_) http://www.ayresnarita.com/show_entry/internet_explorer_error_validating_file_type,_when_uploading_images_using_paperclip_(_ie7,_ie6_mine-type_) This past week, I got a Brazilian customer and consequently I had to write the text in Brazilian Portuguese.

In my case I had, Mac OSX Leopard, Passenger and ImageMagick installed using MacPorts. Every time I asked ImageMagick to crop my images on my model, Paperclip would only save the original version of the image and fail to save the cropped copy. The intriguing part was that examining the logs, nothing related to the error could be found. <p><a href="http://feedads.g.doubleclick.net/~a/QbV1Oadh5MYdfPLENeVZbA62KPI/0/da"><img src="http://feedads.g.doubleclick.net/~a/QbV1Oadh5MYdfPLENeVZbA62KPI/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/QbV1Oadh5MYdfPLENeVZbA62KPI/1/da"><img src="http://feedads.g.doubleclick.net/~a/QbV1Oadh5MYdfPLENeVZbA62KPI/1/di" border="0" ismap="true"></img></a></p><img src="http://feeds.feedburner.com/~r/ayresnarita/~4/ZBwJ6uS8G0I" height="1" width="1"/> 5 February, 2009 http://feedproxy.google.com/~r/ayresnarita/~3/ZBwJ6uS8G0I/paperclip_on_mac_osx_leopard_development_environment_fails_silently_when_processing_images http://www.ayresnarita.com/show_entry/paperclip_on_mac_osx_leopard_development_environment_fails_silently_when_processing_images I made a little list of the methods that I use the most, to serve as a quick guide to string manipulation for RoR.

Sometimes when you have a logo on the top of your website that also serves as a "home button", and when you click on it, a one pixel dotted border wraps around it? That usually does not bother the regular "Joe", but because your "OCD" can't be easily controlled, it gets right under your skin. Besides the looks, there is also that time you use a link to trigger an AJAX action, and there it is again, ruining your so perfectly designed website.
