引述 :『The choice before you 1. InstantRails—an all-in-one package (similar to LAMP), contains Apache, MySQL, Ruby and Rails, all preconfigured and ready to run. (see InstantRails for more info). Best option for beginning Rails developers. Note that the database used is MySQL—for non-beginners who wish to use another database (Oracle, Microsoft SQL Server, PostgreSQL, etc.), you will want to manually install Ruby and Rails. 2. RubyStack—A preconfigured, ready to run installer for Apache, MySQL, Rails and a number of extensions such as Mongrel and ImageMagick. It runs on Windows, OS X and most Linux versions. 3. Install and configure Apache and the other required components individually. (see below for more info)』

引述 :『Recently for Obsidian Portal, we decided that we wanted to move some particularly intensive graphic processing offline from the main server. It was simply consuming too much CPU time and making the entire site sluggish. Luckily for us, it was already set up as a background process that only needed to connect to the database and Amazon S3. So, to do it on a whole new server wouldn’t require changing any of the algorithms.』

引述 :『Good lord do I ever hate input tags. (YUI hates them too, but I’ll leave that story for another time). All the different types should really have been different tag names, and they are a total pain to use with CSS. As such, I used to end up doing tedious stuff like adding a :class option to every form element when writing Rails templates. A while back, I tried to patch Rails to get it to do this automatically, but its test suite totally baffled me at the time by applying the classes in some places but not others.』

引述 :『This plugin, greatly inspired by Jim Morris' blog post (http://blog.wolfman.com/articles/2007/08/07/bit-vector-preferences), aims to make it easy and flexible to store boolean preferences for an ActiveRecord model. This can be also used as a very quick way to setup an ACL. 』

引述 :『 RailRoad generates class diagrams from Ruby on Rails applications as DOT graphs. It produces models and controllers diagrams with a complete description (methods, attibutes) or just with bubbles and arrows, including association and inheritance relations.』

引述 :『Some might call it the Slashdot Effect, other will say the ‘Got Dugg’. But the truth is that your app may some day experience a sudden increase in traffic and attention you didn’t anticipate. The important thing is to keep your app up-and-running and most importantly accessible. You can take several steps to reach this goal. You may enable caching, or if it comes to that, put up a static page until the majority of traffic has receded. There is one solution I don’t read a lot about: throttling. Throttling means that you disable certain features of your app when traffic is high. Recently we needed to do this for a client. The result is the Throttling plugin. The throttling plugin monitors the load of your server and allows you to disable certain features of your app when the load is too high. For example: let’s say you have an app that allows people to upload and share files. Your site just got dugg, and the load on your server is so high it’s about to explode. What do you do? Take your site off-line? Call the A-Team? No, with the throttling plugin you can specify that the upload form gets disabled when the server load exceeds 8.00. When the load drops again, the form is enabled again automatically. E’nuf said!』
