Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet.

Looking for some thrillers that take place entirely in a single enclosed space? Agent Orange from Quiet Earth has counted down 13 of the most nail-biting flicks confined to four walls.

The trend towards well scripted, high concept thrillers that take place in just one location is truly peaking, and in anticipation of the claustrophobic thrills of both Devil and Buried on DVD and Blu-ray right away we thought we would countdown our favourite thrillers that take place in just one room.

zbackup is a globally-deduplicating backup tool, based on the ideas found in rsync. Feed a large .tar into it, and it will store duplicate regions of it only once, then compress and optionally encrypt the result. Feed another .tar file, and it will also re-use any data found in any previous backups. This way only new changes are stored, and as long as the files are not very different, the amount of storage required is very low. Any of the backup files stored previously can be read back in full at any time. The program is format-agnostic, so you can feed virtually any files to it.

This is achieved by sliding a window with a rolling hash over the input at a byte granularity and checking whether the block in focus was ever met already. If a rolling hash matches, an additional full cryptographic hash is calculated to ensure the block is indeed the same. The deduplication happens then.
