instead of stroing plain text passwords, use strong hashing function high computation cost , random salt thwart rainbow attacks etc. but when user in session, typically or username stored along hash of password cookie authenticate sesssion. if user's browser cookie space compromised, doesn't attacker obtain easier target of cracking username+ session hash, instead of username + pass hash? in django example, passwords hashed pbkdf2 or bcrypt, session hashes use less complex hmac , no random salt. security issue? if yes, right way handle sessions? for each session, suggest use dedicated sessionid - random long 128bit value. and, keep session key as: username:sessionid:hash where hash = sha1(sessionid|username|client_ip|secret_server_side_password); every time, when receive cookie, need again compute hash, , compare received one. as result, cookie useless after session closed (mismatch sessionid). moreover, if cookie stolen active session, server can

javascript - How to prevent jquery validator to send default element name and value? -

i have jquery validator plugin , need have ajax validation method. first of all, tried use remote , understand sends element's value , uses element's name. if need other parameter name instead of element's name? method can applied different form elements class , need sure send same parameter element's value. so, if have this: <input name="zip1" class="zip" /> <input name="zip2" class="zip" /> and rule config this: remote: 'http://example.com' then ajax calls 'example.com/?zip1=value' , 'example.com/?zip2=value' , while need have specific parameter name. another thing need process response , i'm not sure how remote . so i'm thinking creating custom method instead of using remote , ajax call parameter name want, process response , set validation status. is there better solution?

c# - DbSet.Add & DbSet.Remove Versus using EntityState.Added & EntityState.Deleted -

in entity framework 6 there multiple way of adding / removing entities, example adding entities, can use:- b.students.add(student); db.savechanges(); or db.entry(student).state = entitystate.added; db.savechanges(); and when deleting object:- db.entry(studenttodelete).state = entitystate.deleted; db.savechanges(); or db.remove(studenttodelete) db.savechanges(); i did not find resources talks differences , , of online tutorials mention both approaches if same. have read reply on article link using dbset.add set status entity , related entities/collections added, while using entitystate.added adds related entities/collections context leaves them unmodified, , same thing applies dbset.remove & entitystate.deleted so these differences correct ? edit as understand graph operation means both parent , child got deleted/added , if parent marked deletion or addition. did these 2 tests :- using (var db = new testcontext()) { var = new department { departmen

algorithm - How is worst case time complexity of constructing suffix tree linear? -

i have trouble understanding how worst case time complexity of constructing suffix tree linear - particularly when need build suffix tree string may composed of repeating single character such "aaaaa". even if construct compressed suffix tree "aaaaa", won't able compress nodes since no 2 edges starting out of node can have string-labels beginning same character. this result in suffix tree of height 5, , @ each insertion of suffix, need keep traversing root leaf. here how approached: suffixes: a, aa, aaa, aaaa, aaaaa create root node, create edge bearing 'a' , connect new node, left bears "$", , repeat process until can aaaaa. this result in o(n^2) instead of o(n). missing here? i agree comments, here more details: the procedure describe forming aaaaa tree o(n), not o(n^2). node , leaf creation constant-time operations, , perform them n==5 times. assumption of o(n^2) seems based on idea you'd traverse root leaf in
