hash

问题 I have an array of hashes as given below: user_quizzes = [{:id => 3897, :quiz_id => 1793, :user_id => 252}, {:id => 3897, :quiz_id => 1793, :user_id => 475}, {:id => 3897, :quiz_id => 1793, :user_id => 880}, {:id => 3897, :quiz_id => 1793, :user_id => 881}, {:id => 3897, :quiz_id => 1793, :user_id => 882}, {:id => 3897, :quiz_id => 1793, :user_id => 883}, {:id => 3897, :quiz_id => 1793, :user_id => 884}] Also, based on a particular condition I took the values of ' user_id ' key from the same

问题 So, I am new to url rewriting, and was wondering if it is possible to rewrite the url when a hash comes into play. For instance, I have the following URL: http://testdomain.com/#/test.php Is there a way to rewrite this to: http://testdomain.com/index.php?url=test.php I am not sure whether the hash effectively makes this 'invisible' on the php side. I tried to capture the request URL this way, and it does not read anything from the hash on. 回答1: After reading more up on this, I have found it

问题 I'm using curtain.js and would like to keep a DIV (which holds navigation) visible at all times except for when the user is looking at the very first panel, i.e. at the top of the page. Currently the DIV resides within panel two I'm thinking perhaps of using the hash change as you scroll through the page to trigger an append to the body. Curtain.js creates an individual URL for each panel and the URL changes each time a panel is brought into view. I can append the div to the body (below) but

问题 I am trying to avoid duplicates in my mp3 collection (quite large). I want to check for duplicates by checking file contents, instead of looking for same file name. I have written the code below to do this but it throws a MemoryError after about a minute. Any suggestions on how I can get this to work? import os import hashlib walk = os.walk('H:\MUSIC NEXT GEN') mySet = set() dupe = [] hasher = hashlib.md5() for dirpath, subdirs, files in walk: for f in files: fileName = os.path.join(dirpath,

问题 I want to encrypt some strings based on SHA1 algorithm in both C#.Net and Oracle 10g. My algorithm in C#.Net: string salt = "123"; System.Security.Cryptography.SHA1 sha = System.Security.Cryptography.SHA1.Create(); byte[] preHash = System.Text.Encoding.UTF32.GetBytes(salt); byte[] hash = sha.ComputeHash(preHash); string password = System.Convert.ToBase64String(hash); password = password.Substring(0, 8); // password value is: "7yP7/lkJ" In Oracle: Create Or Replace Function Sha1(P_Value

问题 I am trying to learn to use PBKDF2 hash functions for storing passwords in the database. I have a rough draft of the procedure that I'll be using to generate the hashed function. But while I am creating the table in PL/SQL Developer which will hold the generated hashed password, what should I declare the data type for the encrypted password variable? It might be a lame question but I'm trying to learn online. It would be a huge help if I can get links for further study as well. thank you.

问题 I have a question regarding the validate a hashed text in the database. Right now, UserType that has been registered in the database is hashed like the image below: I want it to when there is an Administrator text that is stored as hash in the database, the program will validate the hash and check if the validation is an Administrator text. If yes, then it will simply remove the Administrator text in the combo box list. The reason why I stored the UserType to the database by Hash, is I am

问题 Normally I anonymize my data by using hashlib and using the .apply(hash) function. Now im trying a new approach, imagine I have to following df called 'data': contributor -- amount payed eric -- 10 frank -- 28 john -- 49 frank -- 77 barbara -- 31 Which I want to anonymize by turning the names all into 'person1', 'person2' etc, like this: contributor -- amount payed person1 -- 10 person2 -- 28 person3 -- 49 person2 -- 77 person4 -- 31 So my first though was summarizing the name column so the

问题 What is solution of extract to array I have array: $arr = array( 'key1' => array( 'name' => 'Value 1' ), 'key2' => array( 'name' => 'Value 2' ) ); I would like get results like this: Array ( [key1] => Value 1 [key2] => Value 2 ) In Cake 2.2 and lower works by Set::extract('{\w+}.name', $arr) but when I would like use Hash by Hash::extract($arr, '{\w+).name') the results not corectly (also Hash::extract($arr, '{s}.name') return incorect. How do this using new Hash class? 回答1: just a follow up

问题 I wrote a script below to analyze two file formats from bedtools (-tab option, -name option) so it could combine the headers if the sequences match. The problem I ran into was that if the sequences matched to multiple names it only printed one of the names that correspond to it. I was wondering if anyone had a suggestion to how to approach this. As I want both the position of the sequence and name. Is there an option through bedtools? My script stores both files into their own hashes and then
