used to develop the kernel with C/C ++ to implement AutoLISP. The whole program is completed with C/C ++ and AutoLISP, which can be expanded by C/C ++/AutoLISP/VB. 3D Max from Autodesk is also equipped with a max script. 3. Mathematica, developed with C kernel, implements the Mathematica language. The entire program is completed in C and Mathematica languages.

　　 1. Digital signature The original Merkle tree was designed to efficiently handle Lamport one-time signatures. Each Lamport key can only be used to sign a message, but a combination with Merkle tree can be signed with multiple Merkle. This method has become an efficient digital signature framework, namely Merkle Signature Scheme. 2. Peer Network The Merkle tree is used to ensure that blocks of data received from other nodes are not corrupted and not replaced, and even checking that other node

The hansh value of BT seeds is calculated. Recently, I am suddenly interested in BT seeds (do not ask why) 1. BT seeds (concept) BT is a distributed file distribution protocol. Each file downloader continuously uploads downloaded data to other Downloaders while downloading. This ensures that the faster the download, the faster the upload, to implement notification download 2. How does BT download and upload files simultaneously? Starting from the file itself, the BT file contains two parts of

-peer Network In Peer-to-peer networks, Merkle tree is used to ensure that blocks of data received from other nodes are not corrupted and not replaced, or even that other nodes do not deceive or publish false chunks. We are familiar with the BT download is the use of Peer-to-peer technology to allow data transmission between the client, one can speed up the download speed, and secondly reduce the burden of downloading the server. BT is BitTorrent, is a central index of Peer-to-peer file Analysis

Http://torrentfreak.com/10-tips-tricks-for-private-bittorrent-sites-080323/ On private torrent sites, everything revolves around ratios. A ratio (or 1.0) means that you 've downloaded exactly the same amount of data as you 've uploaded. thus a 0.80 ratio indicates that you 've uploaded less than you 've downloaded, Which is hurtful to the health of the torrent. inversely, a 3.0 ratio means you 've uploaded

Seems that appear in the torrent world do not understandMemorandum or methodology behind scene and P2P, so perhaps it's time that we explain a little bit about the history of Peer to Peer, open torrent sites, the "P2P" groups, and "The scene ". there is alot of historical context, propaganda, truth, and hidden despiseThat comes from this mystery, And we'll dig a little deeper now.For years, peer to peer com

convert bt seed file to magnetic link The BT seed file is not easy to store relative to the magnetic chain, and storing BT files on the website can easily cause copyright disputes, while the magnetic chain is relatively less risky. and many forums or websites restrict the type of file upload, share a BT seed also need to change the file suffix or compression once, others need to download time to download the operation of the seed. So it is good to convert BT seeds to a smaller footprint and to

I've been interested in Gottfried Leibniz for years, especially since he seemed to want to create a tool like Mathematica and Wolfram Alpha 3 centuries ago and probably write a new science. So, on a recent trip to Germany, I was thrilled to be able to visit the Leibniz Museum in Hanover.Flipping through his yellow manuscript (still quite enough to withstand my touch), I tried to imagine his thoughts in writing these chapters, trying to connect what I
