I have found a small oss project (one file) in someone's blog a few months ago. The license is Attribution-ShareAlike 2.5 Generic. I sent a mail to the author if I can put this in github but got no response back. Meanwhile his blog has been shut down.I am not a lawyer, but this seems legal to republish the code (with appropriate attribution) in github. Am I right? Is this moral? Maybe the guy just wants to disappear for a while...
Is it legal / moral to republish oss project of an author that does not respond?
open source;licensing
If it's under a license that says you can share it around but you have to attribute it to the original author, then you can share it around but you have to attribute it to the original author.  It's really that simple.I've seen more than one open-source project being hosted and maintained by someone other than the original author when the guy who wrote it lost interest (or just no longer had time to keep it running.)  There's no problem with you doing the same as long as the code's released under a license that allows you to do so.
