  • Opensource.com (Posted by bob on Aug 19, 2019 10:57 AM EDT)
  • Groups: Linux; Story Type: News Story
The humble mv command is one of those useful tools you find on every POSIX box you encounter. Its job is clearly defined, and it does it well: Move a file from one place in a file system to another. But Linux is nothing if not flexible, and there are other options for moving files. Using different tools can provide small advantages that fit perfectly with a specific use case.

How to create a vanity Tor .onion web address

  • Opensource.com (Posted by bob on Aug 15, 2019 5:34 PM EDT)
  • Groups: Python; Story Type: News Story
Tor is a powerful, open source network that enables anonymous and non-trackable (or difficult to track) browsing of the internet. It's able to achieve this because of users running Tor nodes, which serve as intentional detours between two otherwise direct paths. For instance, if you are in New Zealand and visit python.nz, instead of being routed next door to the data center running python.nz, your traffic might be routed to Pittsburgh and then Berlin and then Vanuatu and finally to python.nz. read more
