duplicates

问题 I've spend couple of hours on this problem. I have a multidimension array with fonts details and I want to merge it to send one request to google web fonts. (Each array describe font details of different html tag) Anyone can help me with that? Input: Array ( [1] => Array ( [family] => Abril Fatface [weight] => regular [charset] => latin,latin-ext ) [2] => Array ( [family] => Akronim [weight] => regular [charset] => latin ) [3] => Array ( [family] => Akronim [weight] => regular, bold [charset]

问题 I have a rather big dataset of N documents with less than 1% of them being near-duplicate which I want to identify. I have many number fields, and a few text fields. I consider two documents in the data set close if... all but one, two or three data fields are fully identical. corresponding text fields of two documents are only a few edits away (that's the Levensthein distance used by ElasticSearch). How would you approach this challenge of identifying fuzzy duplicates with ElasticSearch ? I

问题 I have a repository on a pc with approximate size of 70GB and when I copied it (not clone, just simple copying) to my mac it shows that some files are untracked while they are already tracked. When I added them, they appeared to be duplicated in the repo objects info but not in the working tree of course. So I made a hard reset to the last commit but the files appeared again as untracked. How can I solve this problem? (knowing that the repo on the pc is working well) 回答1: Don't copy a

问题 In MySQL, you can insert a row and update the 'last insert ID' at the same time. I'm using this trick to be able to insert items conditionally (uniqueness) and still get the unique ID in all cases. The code below works. The problem is that the ON DUPLICATE KEY statement also updates the Auto_increment value. Is it possible to avoid that? CREATE TABLE T( id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, X VARCHAR(64) NOT NULL UNIQUE ) ENGINE = InnoDB DEFAULT CHARSET=utf8; INSERT INTO T(X) VALUES ('x

问题 If I have a list like this one: mylist = [[1,2,3], ['a', 'c'], [3,4,5],[1,2], [3,4,5], ['a', 'c'], [3,4,5], [1,2]] What is best way to remove duplicate sub-lists? Now I use this: y, s = [ ], set( ) for t in mylist: w = tuple( sorted( t ) ) if not w in s: y.append( t ) s.add( w ) It works, but I wonder if there is better way? Something more python-like? 回答1: Convert the elements to a tuple*, then convert it the whole thing to a set, then convert everything back to a list: m = [[1,2,3], ['a',

问题 I have a table with 500,000+ records, and fields for ID, first name, last name, and email address. What I'm trying to do is find rows where the first name AND last name are both duplicates (as in the same person has two separate IDs, email addresses, or whatever, they're in the table more than once). I think I know how to find the duplicates using GROUP BY, this is what I have: SELECT first_name, last_name, COUNT(*) FROM person_table GROUP BY first_name, last_name HAVING COUNT(*) > 1 The
