Conceptual Class Diagrams Figure 1 depicts a start at a simple UML class diagram for the conceptual model for a university. Classes are depicted as boxes with three sections, the top one indicates the name of the class, the middle one lists the attributes of the class, and the third one lists the methods. By including both an attribute and a method box in the class I'm arguably making design decisions in my model, something I shouldn't be doing if my goal is conceptual modeling. Figure 1. Enrollment is an associative class, also called a link class, which is used to model associations that have methods and attributes. Figure 2 depicts a reworked version of Figure 1, the associative class has been resolved. Marshill/taxonomy. Object-relation mapping put on rails. Cucumber - Making BDD fun. Thoughtbot/paperclip.
Recommender system. Recommender systems or recommendation systems (sometimes replacing "system" with a synonym such as platform or engine) are a subclass of information filtering system that seek to predict the 'rating' or 'preference' that user would give to an item. Recommender systems have become extremely common in recent years, and are applied in a variety of applications.
The most popular ones are probably movies, music, news, books, research articles, search queries, social tags, and products in general. However, there are also recommender systems for experts, jokes, restaurants, financial services, life insurance, persons (online dating), and twitter followers . Overview The differences between collaborative and content-based filtering can be demonstrated by comparing two popular music recommender systems - Last.fm and Pandora Radio. Each type of system has its own strengths and weaknesses. Recommender system is an active research area in the data mining and machine learning areas. Openx-1.0.0 Documentation.
Ruby On Rails Security Guide. 1 Introduction Web application frameworks are made to help developers build web applications.
Some of them also help you with securing the web application. In fact one framework is not more secure than another: If you use it correctly, you will be able to build secure apps with many frameworks. Ruby on Rails has some clever helper methods, for example against SQL injection, so that this is hardly a problem. In general there is no such thing as plug-n-play security. The Gartner Group however estimates that 75% of attacks are at the web application layer, and found out "that out of 300 audited sites, 97% are vulnerable to attack". The threats against web applications include user account hijacking, bypass of access control, reading or modifying sensitive data, or presenting fraudulent content. In order to develop secure web applications you have to keep up to date on all layers and know your enemies.

HTML5 enabling script. 7 Jan Since HTML5 is getting more attention by way of marking up our new pages, and the only way to get IE to acknowledge the new elements, such as <article>, is to use the HTML5 shiv, I’ve quickly put together a mini script that enables all the new elements.
Download html5shiv.js and must be inserted in the head element (this is because IE needs to know about the element before it comes to render them – so it can’t sit in the footer of the page, i.e. below the elements in question). I’ve updated this post to link to Alexander Farkas’s version of the shiv – it’s the very latest and my simple one line script. Community, open source ruby on rails development : thoughtbot.

Learning Ruby on Rails, CSS & jQuery - Building a webapp for designers (Part 2) - Comp Versions Blog. 28 Apr 2011 This is a series of posts, where I detail how I built CompVersions and what choices I made along the way. In the first part of this series I spoke about the legal side. Now I get into learning the development-side.

I’m a little hesitant to do this because I am a non-developer and I am learning and I’m completely on my own with this and don’t have anyone to ask questions so if something breaks (which it did yesterday in a gem version) I’m at a dead end and you will probably make the same mistake if you follow my instructions.
