duplicates

问题 I have a namespace with inline function that will be used if several source files. When trying to link my application, the inline function are reported as duplicate symbols. It seems as if my code would simply not inline the functions and I was wondering if this is the expected behavior and how to best deal with it. I use the following gcc options: -g -Wextra -pedantic -Wmissing-field-initializers -Wredundant-decls -Wfloat-equal -Wno-reorder -Wno-long-long The same code style seems to compile

问题 I have a list of sets : L = [set([1, 4]), set([1, 4]), set([1, 2]), set([1, 2]), set([2, 4]), set([2, 4]), set([5, 6]), set([5, 6]), set([3, 6]), set([3, 6]), set([3, 5]), set([3, 5])] (actually in my case a conversion of a list of reciprocal tuples) and I want to remove duplicates to get : L = [set([1, 4]), set([1, 2]), set([2, 4]), set([5, 6]), set([3, 6]), set([3, 5])] But if I try : >>> list(set(L)) TypeError: unhashable type: 'set' Or >>> list(np.unique(L)) TypeError: cannot compare sets

问题 So the first fact section in this HTML import article states that html imports know better than to request (and execute - if javascript) resources multiple times. This works within the framework of HTML imports but doesn't work for other type of imports (as in javascript). In this network view of the devtools you can see Polymer.html being loaded first from javascript ( d3.js ) then again from HTML imports ( my-app.html ) which I wasn't expecting. Is there a way to explicitly tell HTML

问题 I have the following python code which almost works for me (I'm SO close!). I have text file from one Shakespeare's plays that I'm opening: Original text file: "But soft what light through yonder window breaks It is the east and Juliet is the sun Arise fair sun and kill the envious moon Who is already sick and pale with grief" And the result of the code I worte gives me is this: ['Arise', 'But', 'It', 'Juliet', 'Who', 'already', 'and', 'and', 'and', 'breaks', 'east', 'envious', 'fair', 'grief

问题 Do you have any idea? Why XCode compilation give this result? ld: duplicate symbol _kJSONDeserializerErrorDomain in /Users/Shared/_BUILDS_/Debug-iphoneos/libLACDLibrary.a(CJSONDeserializer.o) and /Users/Shared/_BUILDS_/Debug-iphoneos/libLACDLibrary.a(CJSONDeserializer.o) 回答1: Hey, you probably have a duplicate reference in XCode to CJSONDeserializer, so it's compiled and linked twice. 回答2: I have exactly the same problem. And it only complains for arm6 build (not arm7 build). I found a

问题 Let's say I had a MySQL database with the following five records in a table: ID: 1 Field1: A Field2: B Field3: C ID: 2 Field1: D Field2: E Field3: F ID: 3 Field1: A Field2: H Field3: I ID: 4 Field1: J Field2: K Field3: A ID: 5 Field1: M Field2: D Field3: O Notice that the following values are duplicated: ID 1, field 1 has the same value as ID 3, field 1 and ID 4, field 3. ID 2, field 1 has the same value as ID 5, field 2. Is there a SELECT statement that could find all of the above duplicates
