i'm using defaulthttpclient threadsafeclientconnmanager on android (2.3.x) send http requests rest server (embedded jetty). after ~200 seconds of idle time, server closes tcp connection [fin]. android client responds [ack]. should , leave socket in half-closed state (server still listening, can't send data). i expect when client tries use connection again (via httpclient.execute ), defaulthttpclient detect half-closed state, close socket on client side (thus sending it's [fin/ack] finalize close), , open new connection request. but, there's rub. instead, sends new http request on half-closed socket. after sending half-closed state detected , socket closed on client-side (with [fin] sent server). of course, server can't respond request (it had sent [fin]), client thinks request failed , automatically retries via new socket/connection. the end result server sees , processes 2 copies of request. any ideas on how fix this?

i looking hour, didn't find anything. read tutorial resource files , decided try them. surprised when saw output, because resource files changed in dlls , weren't in .exe file. my question are: how these files safe? what safe store in them? the first google hit on "resource files security site:msdn.microsoft.com" states: caution do not use resource files store passwords, security-sensitive information, or private data. they don't no reason: resource file default not encrypted or obfuscated, program resource editor, msil.exe, or justdecompile can see contents of resource file. you can apply encryption using sort of key, again you'd have store key somewhere decrypt resources. key subject same problems: securely store that, attacker can't use decrypt resources? it's nigh impossible if have distribute program, alternate solution. perhaps explaining you're trying helps towards useful answer.

i believe have simple syntax problem in sql statement. if run code, error in database query. $user = $_get['linevar']; echo $user; // testing - url variable echos correctly $sql = "select * `useraccounts` `name` = $user"; $result = mysql_query($sql) or die("error in db query"); if replace $user in $sql string 'actualname' or known record in table, code works fine. using $ variable incorrectly in sql string? you need surround value you're getting $user quotes, since it's not number: $sql = "select * `useraccounts` `name` = '$user'"; just note, should read on sql injection, since code susceptible it. fix pass through mysql_real_escape_string() : $user = mysql_real_escape_string( $_get['linevar']); you can replace or die(); logic bit more informative error message when bad happens, like: or die("error in db query" . mysql_error());

i'm trying convert longish hollow "data" class named tuple. class looks this: class node(object): def __init__(self, val, left=none, right=none): self.val = val self.left = left self.right = right after conversion namedtuple looks like: from collections import namedtuple node = namedtuple('node', 'val left right') but there problem here. original class allowed me pass in value , took care of default using default values named/keyword arguments. like: class binarytree(object): def __init__(self, val): self.root = node(val) but doesn't work in case of refactored named tuple since expects me pass fields. can of course replace occurrences of node(val) node(val, none, none) isn't liking. so there exist trick can make re-write successful without adding lot of code complexity (metaprogramming) or should swallow pill , go ahead "search , replace"? :) set node.__new__.__defaults...

i trying read msmq information on remote machine. the main difficulty experience getting name of queue. names of queues pretty long, more 64 characters. using wmi names truncated 64 characters, results me in queuenames can't differentiate (similar prefix first 64 characters). i tried using .net 3.5 sp1 , wmi multi query tool , no differences. not couldn't read name, providing suffix make difference wmi query didn't also. any hints how make work? there old entry in ms support db explanation behavior. although there (2004) said might fixed in vs 2005. either has never been fixed, or maybe there different wrong. i not think have chance getting real long-length names using wmi. john breakwell has blogged it: how long msmq queue names displayed ... or not instead limit in how queue names stored in active directory. [...] public queues, though, first 64 characters fit in field used store name in active directory , remainder of name gets ...

if have class, call x , x contains collection (assume not using 1 of synchronized colections, normal one). if write own method synchronized add()- how locking work? locking done on instance of x, , not on collection object? so synchronizing add() method not stop many instances of x calling add() , inserting collection- therefore still have threading problems? a synchronized method locks object. if x.add synchronized, prevent concurrent execution of other synchronized methods of same x object. if out of x object has access same collection, collection not protected. if want collection protected, make sure not accessible rest of world in way other synchronized method of x . also, bit unclear in question, note synchronized non-static method locks object . assuming each x instance have collection of own, won't interfere each other. another option, btw, lock collection instead of x object: void add(object o) { synchronized(mycollection) { mycollection...
