hash

问题 I'm looking to change my array of hashes, to combine all hashes with same keys and different values into same hash, here is what I mean: [ [0] { "Property 1" => { "Portal" => #<Client:0x70aa253d> { :team_id => 1, :cap_id => 25, :user_id => 145, :active => true, :created_at => Wed, 18 Mar 2015 11:52:11 EDT -04:00, :updated_at => Wed, 18 Mar 2015 11:52:11 EDT -04:00 } } }, [1] { "Property 2" => { "Client Solutions" => #<Client:0x70aa221c> { :team_id => 2, :cap_id => 25, :user_id => 145, :active

问题 I have an input file which looks like below =IP1 abc[0] abc[1] abc[2] =IP2 def[4] def[8] def[9] I need to get the output in the below format - =IP1 abc[0-2] =IP2 def[4,8-9] I have been trying to achieve the above using hashes where I read each line of the file and then split(with'[') each line, I keep the first part as key and read the file again to keep the values in an array for the hash keys. But I am getting stuck in a loop. Can anyone provide help on how to achieve the above ? 回答1: There

问题 I am trying to merge an array of hashes based on a particular key/value pair. array = [ {:id => '1', :value => '2'}, {:id => '1', :value => '5'} ] I would want the output to be {:id => '1', :value => '7'} As patru stated, in sql terms this would be equivalent to: SELECT SUM(value) FROM Hashes GROUP BY id In other words, I have an array of hashes that contains records. I would like to obtain the sum of a particular field, but the sum would grouped by key/value pairs. In other words, if my

问题 I am trying to migrate some stored procedures to C# code. I am trying to find what is equivalent for this function HASHBYTES('sha1', password) in C# code. Generated values of HASHBYTES('sha1', "Glenw00d@3") in T-SQL is "зmG>”TëÏåÈ“ÇOó26¥" Does C# have an equivalent of this T-SQL function or not? UPDATE: I tried to use this code: public static class SHA1Util { /// <summary> /// Compute hash for string encoded as UTF8 /// </summary> /// <param name="s">String to be hashed</param> /// <returns

问题 Fact A. Based on Pigeonhole Principle, every hash functions has infinite number of collisions, even if none is found yet. Fact B. Re-hashing a hash, like hash(hash(password)) is not more secure than hash(password), actually hash(hash(password)) open up a collision attack that is not possible with hash(password). Fact C. Based on B, by increasing iterations, we reach a point that most passwords and salts will return same constant hash value. I mean probability of colliding will be high, even

问题 To be Google friendly, I want to change this script a little bit. I have a one page layout, where I use jQuery Cycle to animate between content. The script, as it is now, displays the current slide's number in the URL. Ex. "index.html#1" or "index.html#4". It looks horrible and I think Google would think too... ;-) I want it to display the divs #anchor instead of its index, so the url would be "index.html#Projects" instead The HTML menu: <div id="menu"> <ul> <li><a href="#About">About</a></li

问题 i have the following structure... $output = '<li><a href="http://forum.example.org">Something</a></li>' Actually $output holds multiple list-items. What's the best and easiest way to apply a #hash to each links href? as in... <li><a href="http://forum.example.org#something">Something</a></li> Any idea how to solve that? edit: btw it should always be the same #hash not as you might think in this example above, the #something is equal to the name of the link. So it should be #something for each

问题 I have tried many methods to try and get the contents of a url, with the hashes effecting the output. I really am not sure how to explain it, but here's an example... Doing: echo file_get_contents('test.com/whatever.php?t1=1&t2=2#this'); Will return the same results as: echo file_get_contents('test.com/whatever.php?t1=1&t2=2'); Even though if I navigate to it in my web browser, it will make a difference. Of course the urls above aren't the actual one's that I am using, but I hope you get the
