There is a problem with the world of illegal piracy that we have online today, but it's not what the RIAA and MPAA want you to think it is. It's that we've become accustomed to participating in illegal copying, and yet it is still illegal. This means that we have the illusion of a body of work that can be built upon, remixed, and combined with new work, but if real artists practice this commercially, we are exposed to legal attack.
Recently, as I was browsing the shelves of my local used book store, I realized that I was engaged in "piracy" of exactly the same kind as what the legacy entertainment industry has slammed as a scourge so terrible that it is worthy of giving up our online freedoms to protect. This is what SOPA is supposed to protect us from.
It has been said that "'best' is the enemy of 'good enough'". The Network File System (NFS) may be a good example. It's often overlooked in favor of more capable (but more complex!) resource sharing software like Samba, which can network easily with Windows computers. But if you have a home LAN with a lot of GNU/Linux machines on it, you don't need Samba. NFS will do just fine, and it's very simple to set up. I've been using this configuration for about 10 years now (essentially since I started using GNU/Linux in the first place).
Need to connect to a Windows server from a computer running GNU/Linux? pyNeighborhood gives you an easy and graphical way to do just that.
