i'm wondering how go implementing macro recorder python gui (probably pyqt, ideally agnostic). in excel instead of getting vb macros, create python code. made tkinter callbacks pass through single class logged actions. unfortunately class doing logging bit ugly , i'm looking nicer one. while did make nice separation of gui rest of code, seems unusual in terms of usual signals/slots wiring. there better way? the intention user can work way through data analysis procedure in graphical interface, seeing effect of decisions. later recorded procedure applied other data minor modification , without needing start gui. you apply command design pattern: when user executes action, generate command represents changes required. implement sort of command pipeline executes commands themselves, calling methods have. once commands executed, can serialize them or take note of them way want , load series of commands when need re-execute procedure.

i think nlogn , nlog(n^2) equivalent, , nlog(logn) has better rt nlogn , nlog(n^2). can confirm? no. big o notation has nothing actual run time. o(n) can run shorter o(1) given n value depending on actual implementation. big o notation comparing how algorithms scale . meaning n increases, how change relative each other. so, example: function add100(x) { (i = 0; < 100; i++) { x++; } return x; } function twice(x) { tmp = x; (i = 0; < tmp; i++) { x++; } return x; } i know these functions can reduced x+100 , 2 * x respectively, demonstration purposes simple , show want them to. (and compilers may optimize them, there may not difference depending on environment). now, add100(x) has algorithmic complexity of o(1) . , double(x) has complexity of o(n) . however, values of x < 100, twice(x) faster add100(x) . arbitrary input won't. won't scale well, is faster range of input. now, trivial implem

i started using jquery templates plugin (the 1 microsoft created), face problem: template bunch of forms bound array of objects; when change on 1 of forms, want bound object update , can't figure out how automate that. here's simple example (real life template , object more complex) : <!-- template --> <script type="text/html" id="tmpltest"> <input type="text" value="${textvalue}"/> </script> <!-- object bind --> <script type="text/javascript"> var obj = [{textvalue : "text1"},{textvalue : "text2"}] jquery("#tmpltest").tmpl(obj) </script> this populate 2 textboxes, each bound value corresponding object. now, if change value in 1 of textboxes, need update corresponding data object's value. idea how that? jquery template doesn't implement two-way data binding, microsoft developed jquery plugin does. scott guthrie post

my users in cases able view web version of database table stores data they've entered. various reasons need include stored data, including number of integer flags each record encapsulate adjacencies , forth within data (this speed , convenience @ runtime). rather exposing them one-for-one in webview, i'd have obfuscated field that's called "reserved" , contains single unintelligible string representing flags can encode , decode. how can efficiently in c++/objective c? thanks! why not convert each of fields hex, , append them string , save value? as long append strings in same order, breaking them apart , converting them numbers should trivial.

is there way add tabbarcontroller view displayed without tabitem must active? if so, how can implemented? update: i have tabbarcontroller 5 tabbaritems. when start app, default first tabitem active. would, however, none of tabbaritems active , view displayed (tabbar remains visible). if type in first tabbaritem, appropriate view becomes visible. well came across need, , must tell had implement own tab bar so. the tabbarcontroller designed have @ least 1 tab active. there few hacks posted online, 1 of them here in stackoverflow. wouldn't waste time trying stuff. didn't work me , quicker start coding being "trial , error" hack can app kicked out of app store. the tabbarcontroller not meant subclass reason. wouldn't recommend extend it. since change in api can make app crash. here's tutorial on how tabbar 1 on twitter app. http://idevrecipes.com/2010/12/17/twitter-app-tab-bar-animation/ i'm sorry can't share code community. contr

in our current codebase, creating classes this my_class = function(){ //do constructor stuff } my_class.prototype = { var1 : 'value', var2 : 'value', var3 : 'value' . . . //etc } there several classes like inherit super class. however, if this, end overwriting superclass' prototype. my_super_class = function(){ } my_super_class.prototype.generic_function = function(){ //all subclasses should have function } my_subclass = function(){ //constructory stuff } //inherit superclass my_class.prototype = new my_super_class(); my_class.prototype = { //oops, there goes superclass prototype... var1 : 'value', var2 : 'value', var3 : 'value' . . . //etc } is there better way my_class.prototype.val1 = 'value'; ... etc after inheriting superclass? follow convention our current codebase because short , point. do use library or framework? if chances can use prototype's object

i think may have found bug latest ie9 release candidate, before log issue on connect.microsoft.com, wanted validate brains-trust here understanding correct. problem: a html form contains input field, name attribute contains character entities (&quot), eg. <input type="text" name="mytext[identifier=&quot;test&quot;]" value="hello"> in ie8, ff, safari & chrome, when form submitted, non-safe ascii chars encoded in http request. above input field sent in post as mytext%5bidentifier%3d%22test%22%5d=hello here, can see square brackets encoded %5b , %5d, equals symbol encoded %3d, , &quot entities encoded %22. in ie9 rc1, input field being sent in post as mytext%5bidentifier%3d% 25 22test% 25 22%5d=hello what seems have happened here is, after non-safe ascii chars encoded, ie9 further encoding percent symbols of %22 %25 (giving %2522). i don't think should doing (and mentioned above, no other b

i have 1..* relationship between user , post . (one user has many posts) post has fk called "userid", maps "userid" field on user table. i tried set fk cascade update/delete, error: 'users' table saved 'posts' table - unable create relationship 'fk_posts_users'. introducing foreign key constraint 'fk_posts_users' on table 'posts' may cause cycles or multiple cascade paths. specify on delete no action or on update no action, or modify other foreign key constraints. not create constraint. see previous errors. i have table called posthelpful. 1 post has many helpful's. helpful has cascading fk user (so when user deleted, helpful's deleted). but think cause of complaint "multiple cascade paths". because if delete user (currently), delete helpfuls. im trying add cacade post also, delete post, try , delete helpful's post (as helpful has cascading fk post). in scenario, cascadi

are sockets programming language independent ? can keep server written in java , client written in c? absolutely. otherwise pretty hard write web browser , web server, example... of course, data communicate on socket may easier read 1 language - example if use java's dataoutputstream , that's going easier manage java @ other end read data. still could read data, format documented. if put absolutely platform-specific data across network though, makes things harder - tricky use object serialized java's objectoutputstream non-java platform, example. but @ raw sockets level, there's no concept of programming language source happened written in.
