Each file now always occupy whole piece sizes and have an independent merkle root hash, so that it's possible to find duplicate files across unrelated torrent files of any piece length.

   • What exactly is the info_Hash in a torrent file

     Top Answer

     Answered Nov 30, 2018 · 72 votes

     So I finally figured it out.

     The “infohash” is the SHA1 Hash over the part of a torrent file that includes:

     • ITEM: length(size) and path (path with filename)
     • Name: The name to search for
     • Piece length: The length(size) of a single piece
     • Pieces: SHA1 Hash of EVERY piece of this torrent
     • Private: flag for restricted access

     To show this a little more I took a random torrent file and used the “BEncode Editor” from Ultima to make it more clearly to me.

     As you can see the the red box marked the information part of the torrent file. The torrent file includes not the Hash of the items, but the hashes of every piece.

     • For item1 with: 1069496548
     • and item2 with: 223
     • It is together: 1069496771
     • With a piece size of: 524288
     • There are 2040 pieces. (1069496771/524288=2039.9032 approximately)
     • The pieces section includes 40800 byte of data what are 81600 + 2 chars in the file.
     • the +2 because 0x marks that this is hexadecimal.
     • A SHA1 hash has 40 0x chars or 20 Byte of data what are 2040 SHA1 hashes.

     I am sorry that this information is about a torrent that leads to a illegal movie, but i wanted to use a torrent that realy exists.

     That's pretty acceptable. Keep in mind that this four minute video will load fully in a little over 10 seconds on most consumer-level broadband connections.

   • What is a good maximum log file size for an iPhone/Android app?

     Top Answer

     Answered Jul 07, 2011 · 0 votes

     That depends on a lot of things. Especially what you need the log file for. Are you sure you even need a log file?

     As an iPhone and Android user I can tell you that I've never looked at a log file for any app that I've used. So chances are that your users will never even look at the log file. If it's not for the users I don't see why you should save it on the phone, since the user is the only one with access to the phone.

     Also if the log file is overwritten when it reaches the maximum size, that indicates that only the last log entry is of interest (since it overwrites all the others). If that's the case the log file should always be the size of the last entry.

     If you want a number I would say 256 KB (or less). That should be small enough to not bother anyone and big enough to log almost anything. However I'm still not convinced that you need that log.

     INQUIRE(FILE=filename, SIZE=file_size)-

     filename is a character scalar, file_size is an integer scalar that will be defined with the size of the file in file storage units ("in bytes" on ifort), or -1 if the size cannot be determined.

   How Torrent files are encoded?

   • Torrent files are encoded with a custom encoding called Bencoding. It supports data types such as Strings, Integers, List, and Dictionaries (which can only hold string keys). Strings are encoded as : . Hence, a string arpit will be encoded as 5:arpit. Integers are encoded as i e. Hence, an integer 10 will be encoded as i10e.

   What is bencoding in BitTorrent?

   • Bencoding is most commonly used in torrent files, and as such is part of the BitTorrent specification. These metadata files are simply bencoded dictionaries. Bencoding is simple and (because numbers are encoded as text in decimal notation) is unaffected by endianness, which is important for a cross-platform application like BitTorrent.

   What is encoding in BitTorrent?

   • The BitTorrent file distribution system defines its own format for serializing structured data, known as bencode or bencoding. It is used in .torrent files and in network communications with trackers. This page provides tools for encoding, decoding, and inspecting bencoded data.

   How big should a torrent be?

   • Current best-practice is to keep the piece size to 512KB or less, for torrents around 8-10GB, even if that results in a larger .torrent file. This results in a more efficient swarm for sharing files. The most common sizes are 256 kB, 512 kB, and 1 MB. Every piece is of equal length except for the final piece, which is irregular.
