i created class of tthread socket operations, thing is, code doesnt work unless add messagebox it, sockets wont work unless put messagebox call before it sleep(2000); //waiting socket come array // messagebox(0, '', '', 0); { wont work unless line uncommented } if server.clientlist[handle] <> nil begin if (server.clientlist[handle].connected) , (appsocket.connected) begin // send data on socket // relay data between server.clientlist[handle] , appsocket; end; assuming using non-blocking sockets, thread needs running message queue , processing loop. why calling messagebox() works - modal dialog pumps calling thread's message queue internally. thread needs call peekmessage() or getmessage() in loop lifetime of connection(s). loop can use msgwaitformultipleobjects() detect when message queue has process, if thread has other things needs do.

i'm getting data file, looks this: [200, "hello", "world"] now, since file, array inside string; turn array using eval() . works fine integer @ start converted ascii char, instead of integer want (the euro sign). how can fix this? you use simplejson module. e.g. >>> import simplejson >>> = simplejson.loads('[200, "hello", "world"]') >>> print [200, 'hello', 'world'] this way "malicious" data such os.execvp() not evaluated jsondecodeerror would thrown.

so, idea store each user "password" or auth value, when auth via cookies compare values. way if cookie somehow stolen has nothing real password. for important operations, changing password etc user needs provide password , validated vs original password (salted, encrypted etc). imo there no reason password , session/auto-login-cookie related in way. yes, i'd make them separate. use random value in cookie , associate server side data it. allows me invalidate cookie server side.

if there constructor like function a() {} then (new a) instanceof === true but on other hand, function a() { return {} } results in (new a) instanceof === false so thinking that function a() { return 123 } would result in same thing. however, when returning number, (new a) instanceof === true how possible? why can't make constructor return else object? (i know making constructor returning number rather useless understand 'why' of behaviour) according spec: if calling constructor returns object, object result of new -expression. if constructor doesn't return object (but undefined or other primitive value), result newly created object. if primitives allowed, constructors have explicitly return (typically " this "), otherwise result undefined (because result of function without return undefined ). needless hassle. additionally, makes sense new can relied on return object.

i using ruby on rails 3.0.9 , validate string can contain characters (case insensitive characters), blank spaces , numbers. more: special characters are not allowed (eg: !"£$%&/()=?^) except - , _ ; accented characters are allowed (eg: à, è, é, ò, ...); the regex know this question ^[a-za-z\d\s]*$ not validate special characters , accented characters. so, how should improve regex? i wrote ^(?:[^\w_]|\s)*$ answer in question referred to (which have been different if i'd known wanted allow _ , -). not being ruby guy myself, didn't realize ruby defaults not using unicode regex matching. sorry lack of ruby experience. what want use u flag. switches unicode (utf-8), accented characters caught. here's pattern want: ^[\w\s-]*$ and here in action @ rubular. should trick, think. the u flag works on original answer well, though 1 isn't meant allow _ or - characters.

when following: function makeaddfunction(amount) { function add(number) { return number + amount; } return add; } var addtwo = makeaddfunction(2); var addfive = makeaddfunction(5); alert(addtwo(1) + addfive(1)); will each instance of makeaddfunction have separate stack or of them use same stack? , order of variables entering , leaving stack matter? each function call creates new function (-context). answer quickly, yes have separate "stacks" in terms of ecmascripts execution contexts . i'm not sure mean "the order of variables entering , leaving stack". ecmascript contexts (objects). there stack of execution contexts called in order. after 1 context finished, parent context continues run until it's finished (and forth). principle lasts long there contextes if not, global context gets attention again.

my question similar another one putting data text_field datetime column. appears need put data text_field in particular order or rails wont accept it. thing is, can't control how user input data. in fact, since added jquery datepicker value user puts in wrong. i thought use date.parse or time.parse or datetime.parse along setter method (mentioned in railscast 32 but doesn't seem working me either. keep getting argument out of range error seems due input being in wrong format. does else use jquery datepicker fill in text field date? magic have add model or controller make work? why difficult? i used timeliness gem overcome problem , submit date in format wanted. along timeliness used validates_timeliness validate date , time, is not in future or anything. to parse string 'mm/dd/yyyy' using timeliness gem do: timeliness.parse(params[:my_date], :format => 'mm/dd/yyyy')
