python 2.7 - How exactly do the hashlib hashers treat input? -

the python 2.7 documentation has hashlib hashers: hash.update(arg) update hash object string arg. [...] but have seen people feed objects not strings, e.g. buffers , numpy ndarrays . given python's duck typing, i'm not surprised possible specify non-string arguments. the question is: how know hasher doing right thing argument? i can't imagine hasher naïvely doing shallow iteration on argument because fail miserably ndarrays more 1 dimension - if shallow iteration, ndarray n-1 dimensions. update unpacks arguments using s# format spec . means can either string, unicode or buffer interface . you can't define a buffer interface in pure python, c libraries numpy can , - allows them passed hash.update . things multiple dimension arrays work fine - on c level they're stored contiguous series of bytes.

google chrome - Only Cookie JSESSIONID set from first Login request is not sent in subsequent requests? -

i not able understand what's going on. on 1 of env. of webapp (written using extjs 4.0) - see login request completes subsequent request fails 401. when digged bit more found in browser(f12) 1st request's response header has jsessionid, set cookie, 2nd request doesn't send in request headers. that's why 2nd request creates new session , returns new jsessionid. in client code request sent, ext.ajax.request({url:'', callback..}) - there no explicit setting of jsessionid or cookie. strange part not cookie keys missing, jsessionid, means cookies not disabled , set browser. why browser not sending jsessionid? tried in firefox/chrome both. also happening in local env., qa env. of webapp working fine. i figured out myself.. issue http://tomcat.apache.org/migration-7.html#session_cookie_configuration thanks people spent time reading question.

c - Why socklent_t * is used in accept() in socket programming? -

in c socket programming accept() declaration looks like: int accept(int sockfd, struct sockaddr *addr, socklen_t *addrlen); i can understand uses of sockfd , struct sockaddr *addr . but why have pass address of length of socket, have been socklen_t . because if accept() function needs length can socklen_t . why protype of function declared in such way? so reason behind using socklen_t * type? in code that's agnostic address/protocol family of socket it's accepting from, may using generic sockaddr_storage structure hold result. initial value of pointed-to socklen_t size of storage; value after accept returns actual size of resulting peer address. also, address/protocol families af_unix have variable length addresses, if know type may not know size.

java - Why class/object name must be explicitly specified for method references? -

when want refer method in current scope still need specify class name (for static methods) or this before :: operator. example, need write: import java.util.stream.stream; public class streamtest { public static int trimmedlength(string s) { return s.trim().length(); } public static void main(string[] args) { system.out.println(stream.of(" aaa ", " bb ", " c ") .maptoint(streamtest::trimmedlength).sum()); } } it's not big problem this , overcrowded static methods class name can quite long. nice if compiler allowed me write ::trimmedlength instead: public static void main(string[] args) { system.out.println(stream.of(" aaa ", " bb ", " c ") .maptoint(::trimmedlength).sum()); } however java-8 compiler doesn't allow this. me seems quite consistent if class/object name resolved in same manner it's done normal method call. support sta...
