i measured how many times can call md4 in 3 seconds. used md4 openssl. noticed interesting issue. when called md4(array, size, digest); directly, app said 5438501 md4's within 3 seconds. when used evp_digest(array, size, digest, null, evp_md4(), null); said did 4787370 md4's in 3 seconds. so direct call faster using evp api? why that? i don't see why evp_digest should faster method uses :-) using evp_digest delegating "him" (it) use hash algorithm. there overhead in this. or perhaps think evp_digest use "magically faster" md4 algorithm "default" md4 algorithm? from md4/md5 (emphasis added) applications should use higher level functions evp_digestinit(3) etc. instead of calling hash functions directly. and evp_digestinit the evp digest routines high level interface message digests. where high level == slower :-) so why should use evp_digest ? it's explained in same page before: the evp inter...

is there anyway create class model? for example, have model.py, 1 of class inside contains: class customers(ndb.model): lastname = ndb.stringproperty() firstname = ndb.stringproperty() license = ndb.stringproperty() birthdate = ndb.dateproperty() remarks = ndb.textproperty() i know can models using dir(model) , , outputs like: ['customers', 'customeraddresses','whatever','__builtins__', '__doc__', '__file__', '__name__', '__package__', 'ndb'] however, there way can use these string inside dir(model) automatically generate class, like: class restcustomers(webapp2.requesthandler): #some code gets model class attributes , displays json string customers = # customer attributes model self.response.headers['content-type'] = "application/json" self.response.write(json.dumps(customers)) i'm not sure if possible, kind of way javascript works, wherein like var mod...

this question has answer here: why margin padding doesn't work in table td , tr? 3 answers i have spent last several hours trying understand why margin css property (at least) td elements ignored. for example, fiddle shows "simulation" of table row using div elements, followed "real" table element single tr . (i give full code @ end of post.) div simulates tr has been given class tr , and, similarly, div s simulate td s have been given class td . css div.tr has been kept close possible tr (the exceptions css directives not apply tr in case). similarly, css div.td , td should identical. in particular: div.td,td{border:1px solid black;} div.td,td{margin:15px;padding:5px} furthermore, each div.td , each td contains empty div element, following dimensions: div.td > div,td > div{width:90px;height:60px;} as can se...

i have 2 lists: var_a = [1,2,3,4] var_b = [6,7] i want have list of dicts follows: result = [{'a':1,'b':6},{'a':1,'b':7},{'a':2,'b':6},{'a':2,'b':7},....] i think result should clear. from itertools import product = [1,2,3,4] b = [6,7] [dict(zip(('a','b'), (i,j))) i,j in product(a,b)] yields [{'a': 1, 'b': 6}, {'a': 1, 'b': 7}, {'a': 2, 'b': 6}, {'a': 2, 'b': 7}, {'a': 3, 'b': 6}, {'a': 3, 'b': 7}, {'a': 4, 'b': 6}, {'a': 4, 'b': 7}]
