Beginners
OK, if you believe you're a beginner and need to warm-up, here's a list of tasks to do using ruby before starting this book.
- Strings
- Print the following string
\x52\x75\x62\x79\x46\x75as it is, it should NOT be resolved to characters. - You have string
RubyFu, convert this string to an array (each character is an element).
- Arrays
- You have the following array
["R", "u", "b", "y", "F", "u"]convert it to stringRubyFu. - You have the following array
["1", "2", "3", "4"], calculate the sum of all elements.
- Files and Folders
- Find all files ending with
.jpgor.pdfor.docxor.zipin your Downloads folder. - Create a folder called
ruby-testfuand copy all found files (from the previous task) into it.
- Network
- Create a simple TCP server listening on port 3211. This server prints
date and time. - Create a simple TCP client to connect to the previous server and print what the server sends.
There are some awesome websites that push your programming skills via interactive challenges and I really encourage you to go through one or more of them.
There are some interactive courses, MOOCs and great resources to learn too:
