Here are one or two I have come across so far and examples:
Applications - Notepad++, Winmerge
Chrome/Firefox Extensions - What Font, Eye Dropper
Learning Resources - Lynda.com, Udemy, CodeSchool
Forums - Programming
Websites/Blogs - Mashable
Will hopefully be a good resource for new tools to try and for newbies to look at.
Please list your favs, Thankyou
