Lecture 4/5: Ruby on Rails

Here's lecture 4/5 on Ruby on Rails

Lecture 4/5 (PPT | Code)

Sorry if the code example was a little boring, but important points to take away are that Ruby is a really cool language, and Rails is a great framework that makes a lot of the typical stuff (form abstract, no SQL, database relationships, etc...) much simpler.

Websites mentioned were:

• Web 2.0 Video
• Video for installing Ruby on Rails
• Top 12 Ruby on Rails Tutorials
• Great Free Book on Ruby

As we start covering JavaScript and DHTML, I recommend you guys fool around creating a basic website and manipulating some CSS styles.

Hurray...Class tomorrow

So we're back on schedule. There's class tomorrow (in PH A18A). There's a cool video and website I want to show you guys, and we'll finish up Ruby on Rails with our example joke website.

Adobe Flex Internship

My future boss at Adobe wants to start recruiting at CMU (as do I). We'll definitely be back next year with more of a plan, but if you would like to intern at Adobe, specifically the Flex team, let me know and shoot me an email with your resume.

No class today

Because of the weather and some laziness, we've decided to delay Rails part II and cancel class today.

Class in PH A18

Just as a reminder, the next class on 2/7/2007 will be in PH A18 and will be on Ruby on Rails

Lecture 3 Resources

Here are some resources relating to the CSS lecture.

Some References:

These links have information regarding CSS and how to use it.

• http://www.westciv.com/style_master/academy/css_tutorial/index.html was the tutorial I used as reference to develop the lecture
  
• http://www.webcredible.co.uk/user-friendly-resources/css/ some articles
  
• The DOM Inspector and Firebug from last time are great for viewing the CSS as you are browsing the net.
  
• http://www.sitepoint.com/subcat/css is the sitepoint tutorial and reference point. sitepoint is a great site for many things web-related.
  

CSS Standards:

As with HTML, the CSS standards are not always adhered to. This allows for many "hacks" to get around browser compatibility. These are some links that explain what will work and where.

• http://www.webdevout.net/browser_support_css.php shows which properties and selectors and such are supported by a few more recent browsers
  
• http://www.quirksmode.org/css/quirksmode.html is a site that explains how your browser handles CSS in "quirks" mode
• http://centricle.com/ref/css/filters/ lists some possible CSS hacks (that you really shouldn't be using) and where these hacks will work.
  

Lecture 3

This is Lecture 3, which is the lecture on CSS. It basically lists a bunch of different property values, but if you weren't in class then you probably didn't hear me go over the important ones. There will be some resources posted that has a link to a CSS reference page, that you can go to if you want to know what a specific property does.

Lecture 3 (PPT)

We also played some Jeopardy and here is the powerpoint for that as well.
