BMP

GIMP

GIMP (GNU Image Manipulation Program) is an extensible Open Source raster image editor (BMP, PNG, JPEG, GIF, ICO, …, GIMP .xcf).

GIF

GIF is a file format for sequences of images (“animations”).

GIFs appear to load quickly because there is no media player or codec initialization time, but are actually less eficient than compressed video (e.g. H.264) because GIFs are not compressed and contain every frame of the animation.

Video codecs compress the changes between frames, in order to avoid basically GIF.

  • There are programs to retrieve the latest .torrent files from RSS and Atom feeds (e.g. a released [episode] of a series or topic)

  • BitTorrent can be run headlessly (as a server daemon) e.g. with an HTTP API, SMTP pattern, web interface, or SSH for enqueuing torrents to download to a central location.

  • BitTorrent does not preserve file permissions or extended attributes, but archives can.

  • For a time, BitTorrent accounted for the largest slice of web traffic; but “now accounts for only 6.3% of total traffic in North America”.

    https://www.sandvine.com/trends/global-internet-phenomena/

BitTorrent Torrent File

A BitTorrent .torrent file includes:

  • SHA-1 checksum hashes of all the pieces of all the files

  • (optional) a DHT key (for trackerless peer discovery)

  • (optional) a list of HTTP BitTorrent Tracker URLs

  • (optional) a list of HTTP Web Seeds.

https://en.wikipedia.org/wiki/Torrent_file

BitTorrent Tracker

A BitTorrent Tracker maintains a list of recently connected peers from which matching pieces can be downloaded.

BitTorrent Client

A BitTorrent Client opens a BitTorrent Torrent File, registers with the given BitTorrent Trackers, looks for peers in a DHT, downloads the pieces of the files listed by choosing faster (more efficient, less costly, ~more local) peers to download from, and, according to the configuration, uploads pieces to other peers.

BitTorrent Seed

A BitTorrent Seed is a complete, checksummed copy of all of the pieces of all the files in a BitTorrent Torrent File which a peer is sharing through a BitTorrent tracker or a DHT.

Web Seeding

Web Seeding is when one or more HTTP servers serve default standby seeds (thus ensuring Availability when no-one is online).

https://en.wikipedia.org/wiki/BitTorrent#Web_seeding

Use Cases:

Note

“Scrambled” DRM content (which may or may not just work when I just copy the file to my other device) can be shared over BitTorrent all the same.
