If you just want to do programming and not some low level stuff (device drivers, etc), then consider using a high level language like Python or Ruby. These languages let you concentrate on getting your stuff going, without having to learn low level stuff like pointers (c/c++) and such. Plus, they provide good to use data structures such as hashes, dictionaries and arrays (and abundance of libraries) which you can make use of in your programming task which you can find them lacking or hard to use in other languages. For Python, go to doc.python.org, For Ruby go to Programming Ruby: The Pragmatic Programmer's Guide
A rudimentary approach to convert your word from one language to another is to use a lookup table (that is, your hashes/dictionary). here's a demo in Ruby
(of course, actual spanish may not be spoken like that.). you can further expand this list by creating a list of such mappings in a database or a flat file. And this is written in like less than a minute. Try doing that with C/C++ (or even Java)
I see you guys encouraged people studied and used C while they were working on UNIX. Does C++ or JAVA matter? And in the past threads, Neo, PxT, and other members recommanded lots good books. I think those people who asked for the references, such as Dominic, had experiences on sys admin or... (8 Replies)

I'm in college now and a part of a subject in this semester is learning UNIX, though the teacher failed to explain the basics, I feel, we got straight to the Unix Terminal and started putting in commands without much explanation what they were for.

Type in commands that do the following.
Part 1
Send the output to a textfile using the "script" command.
Attach the "script" file with your output. Don't worry about any mistakes while you are typing - you don't need to do it over and you don't need to clean up your script file.

RUBY-SWITCH(1)RUBY-SWITCH(1)NAME
ruby-switch - switch between different Ruby interpreters
USAGE
ruby-switch --list
ruby-switch --check
ruby-switch --set RUBYVERSION
ruby-switch --auto
DESCRIPTION
ruby-switch can be used to easily switch to different Ruby interpreters as the default system-wide interpreter for your Debian system.
When run with --list, all supported Ruby interpreters are listed.
When --check is passed, ruby-switch will check which Ruby interpreter is currently being used. If the settings are inconsistent -- e.g.
`ruby` is Ruby 1.8 and `gem` is using Ruby 1.9.1, ruby-switch will issue a big warning.
When --set RUBYINTERPRETER is used ruby-switch will switch your system to the corresponding Ruby interpreter. This includes, for example,
the default implementations for the following programs: ruby, gem, irb, erb, testrb, rdoc, ri.
ruby-switch --set auto will make your system use the default Ruby interpreter currently suggested by Debian.
OPTIONS -h, --help
Displays the help and exits.
A NOTE ON RUBY 1.9.x
Ruby uses two parallel versioning schemes: the `Ruby library compatibility version' (1.9.1 at the time of writing this), which is similar
to a library SONAME, and the `Ruby version' (1.9.3 is about to be released at the time of writing).
Ruby packages in Debian are named using the Ruby library compatibility version, which is sometimes confusing for users who do not follow
Ruby development closely.
ruby-switch also uses the Ruby library compatibility version, so specifying `ruby1.9.1' might give you Ruby with version 1.9.2, or with
version 1.9.3, depending on the current Ruby version of the `ruby1.9.1' package.
