Autorun and digital signature (1)

. For devices that support mobile storage (such as USB flash drives, SD cards, and CF cards), I think Autorun technology is a very powerful method. Then, it runs. It is very simple but practical, similar to the CD/DVD Autorun technology. Windows Mobile directly supports Autorun. In fact, it is easy to implement on Windows CE: runtime runs. To implement this function, you must first create a message queue during initialization to wait for the system device plugging time notification:Code Code hi

Mining of massive datasets-finding similar items

function for a random permutation of rows produces the same value for two sets equals the jaccard similarity of those sets. For a random row arrangement (permutation), the probability of the same value obtained by the minhash of the Two sets is their jaccard similarity. For example, in S1 and S4, The minhash value is a, that is, the two sets contain a, and the probability should be the same as that of jaccard similarity.This ensures the correctness of using minhashing. jaccard similarity serve

= [1,2,3,4,5,6]; Console.log (Array.slice (-1)); [6] Console.log (Array.slice ( -2));//[5,6] Console.log (Array.slice (-3));//[4,5,6] Array truncation This trick is primarily used to lock the size of an array, which is useful if you are deleting elements from an array. For example, your array has 10 elements, but you just want the first five elements, then you can truncate the array by array.length=5. As the following example: var array = [1,2,3,4,5,6]; Console.log (Array.Length);
