(Tech) Learn To Code

Okay, here's a quick list of the references I use in learning to code. This servers as a personal notebook for me to review from time to time, and I don't mind sharing it either.

For the basics/newbies, you might want to start here:

• www.codecademy.com
• code.org/learn
• www.w3schools.com (This one is especially useful even if you're already past being a newbie. This features serveral languages as well.)

Now for the more specific stuff. 

• HTML is the first language I learned. Though the sites above already feature HTML learning, it wouldn't hurt to add another to the list. 
• http://www.htmldog.com/guides/html/beginner/ provides a good reference for HTML by segregating everything by topic.
• https://www.mtholyoke.edu/acad/germ/neh/HTML.html lets one learn HTML in 20 minutes. Then again that'd depend on how fast one can read and comprehend. This site is rather outdated too. I guess it's good as a quick reference for stuff one forgets.
• http://html.net/ lets one systematically learn web programming. This begins with HTML, followed by CSS, PHP and to top it all off, JavaScript.
• 
  
• PERL has quite a lot of references. I'm still starting to learn this stuff, so I'm listing all them search page results here. This borrows syntax from scripting languages, by the way, which makes it actually hard to read at times. But it works wonders nonetheless.
• https://www.google.com.ph/?gfe_rd=cr&ei=v2K4U-a_FqaD8QfjlYG4Bg#q=learn%20to%20code%20PERL
• PHP is also a hurdle I'm trying to tackle. Here are a few of the references I collected so far:
• http://www.phpbuddy.com/
• http://www.phptherightway.com/
• Some good advice regarding PHP here:  http://code.tutsplus.com/tutorials/the-best-way-to-learn-php--net-22287
• Aside from the usual coding there's also scripting. For now I'm limiting the list to BASH.
• The BASH Advanced Scripting guide is awesome. This is as simple as it gets: www.tldp.org/LDP/abs/html/
• It also has a couple of other reference pages that would be essential to say the least:
• The BASH Introduction How-To: www.tldp.org/HOWTO/Bash-Prog-Intro-HOWTO.html
• The BASH guide for beginners: www.tldp.org/LDP/Bash-Beginners-Guide/html/
• Here's also an alternative BASH guide: linuxconfig.org/bash-scripting-tutorial 

This is just an initial. I'll add more references on the list as I go on.
