Briefly about ideone
ideone.com is a... pastebin. But a pastebin like no other on the Internet. More accurate expression would be online mini IDE and debugging tool.
Ideone is an Italian word for great ideas - because ideone.com is a place where your greatest ideas can spring to life.
ideone.com is designed mostly for programmers (but, of course, common plain text can also be uploaded). You can use it to:
share your code (that's obvious - it is a pastebin, isn't it? :)) in a neat way,
run your code on server side in more than 40 programming languages (number still growing)
and do it all with your own input data!
ideone.com also provides free Ideone API which is availabe as a webservice. It's functionality allows you to build your own ideone-like service!
for logged in users Ideone offers possibility to manage their codes, publish multiple submissions at one go, and more.
All codes can be accessed through convenient hash links. Source code pages provide information about the code and its execution: memory usage, execution time, language and compiler version, code itself, input uploaded by the user, output generated by the program and error messages from compilers and interpreters.
It is in great measure your contribution that this service exists - it is you who share your ideas with us and report bugs and suggestions. We hope it is still going to be like this - as long as this site works! Thank you!
