is possible prototype-based programming in scala? i have disagree easy angel... scala objects not need classes (they still have type... not same). ok write val martin = new { val name = "martin" val surname = "ring" def age = calendar.getinstance.get(calendar.year) - 1986 } also structural typing can write functions these objects: def printperson(person: { def name: string; def age: int }) = println("%s (%d)".format(person.name, person.age)) you can call printperson(martin) , print out martin (25) so no need classes or traits if want that. however prototype-based programming still not supported language (imho) not possible clone , extend objects anonymous type. guess write functions that... require massive use of reflection , there no native lanugage support..

how use ant's task proxy? i see there username , password, there no proxy host :( the key bit in get task docs is: proxies . since apache ant 1.7.0, ant running on java1.5 or later can use proxy settings of operating system if enabled -autoproxy option. there 'setproxy' task earlier java versions. proxies turned on, requests against localhost may not work expected, if request relayed proxy. so can use setproxy task older versions of ant, or see docs on proxy config : <setproxy proxyhost="firewall" proxyport="81"/> (the username , password attributes of get task remote system, not intermediate proxies.)

hard explain...let me try: i built script compare 2 users' interests (hobbies) let's assume usera have 44 hobbies, , 13 in common userb (who has 19 hobbies) in pseudo code (where % formula): func %(usera,userb) = 13 ...etc..comparing other users func %(usera, userc) = 2 func %(usera, userd) = 7 given users' hobbies have no limit, can 100, 20 or infinite... how can calculate , show percentage of "compatibility" between usera , rest of world? because thought was, if knew 20 max numebr of hobbies, simple equation (bewteen user , b) percent = 13 / 20 * 100 between usera , userb can display "you match 65%" but problem dont know value 20 (the maxium number)! that's problem! you're close. in example, user compatibility percentage user b = 13 / 19 (total user b hobbies) = 68.4 % user b compatibility percentage user = 13 / 44 (total user hobbies) = 29.5%

i'm implementing standard object oriented library in java. standard includes many messages passing on network through terminals. every message implemented single class. some of fields represented char types , fields have 1 of values defined in standard. example, public class outgoingmessage { private char action; and action has these values, '0' - not print '1' - print '2' - print , forward '3' - print , reply 'f' - forward 'r' - reply also of classes have more 2 fields this. defining constants in class can messy in these situations. so i'm trying implement values as public class outgoingmessage { private char action; public final class actiontypes { public static final char do_not_print = '0'; public static final char print = '1'; ... and using below ... message.setaction(outgoingmessage.actiontypes.do_not_print); ... message.setfoobar(outgoingmessage.foob...

i created uiimageview has custom shadowpath. view moved left , right across screen, need shadowpath have different transformation image layer itself. possible? moving image works, , shadow moves when following: [uiview beginanimations:nil context:null]; [uiview setanimationduration:0.3]; [uiview setanimationcurve:uiviewanimationcurveeaseout]; im.center = location; [uiview commitanimations]; but if try add layer transformation before "commitanimations", shadow take on property right away, example: [uiview beginanimations:nil context:null]; [uiview setanimationduration:5]; [uiview setanimationcurve:uiviewanimationcurveeaseout]; im.center = location; im.layer.shadowpath = [self createperspectiveshadow:im]; //this not animate [uiview commitanimations]; so, question is, there way recalculate shadow during animation? thanks the uiview animations don’t allow animate calayer attributes; try using cabasicanimation instead.

i want execute action doesnt need view. in example "logout" function, ajax call (for example, need number back). should add module? well, i'd rather "flat" script action redirect index page, when done. , in case, put flat script? yes, still want create module (controller) this. for number of reasons: - should want change behaviour, it's in code. - logout action want manipulate current ( sfuser ) user, instance want fire symfony stack, why not create controller. - it's considered 'bad practice', or 'counter-mvc' if start creating kinds of small files small actions. and how hard create new module? ./symfony generate:module frontend user . if don't have view can forward/redirect request. (in action: $this->redirect('homepage'); ). or, ajax-actions, can return required data: if ($request->isxmlhttprequest()) { // set correct header return $this->rendertext(json_encode($data)); }

to astonishment found vb6 code uses declare statements define functions in .dll lives in program folder without being registered on windows. seems supersimple way avoid .dll hell without having resort using side side manifests. can read more somewhere? there snags? the declare statement used "just in time" binding non-activex dlls. until program "touches" declared entrypoint no attempt made load library. it has nothing @ topic of dll hell. muddled thinking can lead people plop activex dlls "next to" exe can result in dll hell because people tend use poor techniques installing , uninstalling applications. poorly designed application deployment plops commonly shared dll or ocx next exe. poorly designed application run, vb6 runtime can't find classes in registry, dll search using windows heuristics, locates dll next exe , calls self-registration entrypoint. innocent, designed applications b, c, d later installed use same dll/ocx ...

i'm having difficulty figuring out how add dropdownlist control single row of data grid. example, if have 2 rows of data in grid, want top normal text data provider, , second row dropdownlist (bound array collection). i've searched high , low solution no avail. appreciated. thanks, conceptually need itemrenderer function, not implemented in mx datagrid. ( may in new spark one, don't know). in lieu of that, create itemrenderer conditionally display dropdownlist. this: <s:mxdatagridrenderer datachange="ondatachange()"> <fx:script> public function ondatachange():void{ if((this.listdata datagridlistdata).rowindex == 0){ label.visible == false; ddl.visible == true; } else { label.visible == true; ddl.visible == false; } } </fx:script> <s:label id="label" /> <s:dropdownlist id="ddl" /> </s:mxdatagridrenderer>

recently customers complained getting garbled emails. mime headers showing, , base64 encoded data, etc. stuff should have been decoded mail clients. after investigating found mail clients (gmx.de webmail name one) inserted blank line after every other line, indeed messing up. following hunch, changed mail sending code replace crlf lf. , lo , behold - mail arrived whole. now, weird, because rfc 5322 explicitly states that 2.3. body the body of message lines of us-ascii characters. 2 limitations on body follows: o cr , lf must occur crlf; must not appear independently in body. huh? bad webmail? or did go wrong somewhere? other webmails (like gmail) have no problems this, , indeed seems majority of people have no problems (since complaints few). just note - i'm sending email through php's mail() function on linux box. underlying mail software seems qmail, i'm not sure. it seems qmail doesn't crlf under similar conditions . ...

i working on web app, extjs makes ajax call jsp, jsp in turn calls java class , returns value , updates in database. now question is, somehow not feel effective way, discovered servets working , wondering if should make ajax call servlet instead of jsp. there other ways better , optimized. please explain. thanks, sixthstring it depends on want returned form ajax call. jsp used generating formatted html. if that's you're looking ajax call, jsp right choice. if you're looking raw data, might skip jsp template , go straight servlet. recommend using json in case, because it's easy work in javascript.

the idea drag icon(of specific file) desktop , release on particular location @ website??? possible implement (by jquery?) i recommend use plupload doing task. because component based on lot of plug-in or feature depend on plug-in available in current browser. still has limitation on drag-drop feature.

i'm working on site serves content via ajax. if click item in menu, content div gets updated $.get response, nothing fancy. i'm implementing history.pushstate allow navigation browser's back/forward button. i have following load content on history navigation: $(function() { $(window).bind("popstate", function() { $.getscript(location.href); }); }); the problem is, when page loaded first time, function $.getscript page loaded again. first time page loaded renders initial html view, on second load renders js view, since js request. how prevent event firing on pages html requests? using native html5 history api you're going run problems, every html5 browser handles api little bit differently can't code once , expect work without implementing workarounds. history.js provides cross-browser api html5 history api , optional hashchange fallback html4 browsers if want go down route. for upgrading website ria/ajax-app...

i have array of prefixes, array of base words , array of suffixes. see every combination can made. example: prefixes: 1 2 words: hello test suffixes: _x _y results: 1hello_x 1hello_y 1hello 1test_x 1test_y 1test 1_x 1_y 1 2hello_x 2hello_y 2hello 2test_x 2test_y 2test 2_x 2_y 2 hello_x hello_y hello test_x test_y test _x _y y how can this? edit: responses, going through solutions seems if there no prefixes, fail combination. should still go through base words , suffixes, without prefixes. function combineall ($prefixes, $words, $suffixes) { $combinations = array (); foreach ($prefixes $prefix) { foreach ($words $word) { foreach ($suffixes $suffix) { $combinations[] = $prefix.$word.$suffix; } } } return $combinations; }

i have facebook token getting graph.facebook.com/me/home url fine. on posts pictures, pull out picture id post can detailed information sizes , urls different images. the problem on feed, don't see "privacy" fields users. way these urls work vary widely. example, photo can viewed while logged out of facebook. photo can viewed long logged in anyone. photo private. when query graph.facebook.com/(photoid) of time false. there permission should getting users don't have here? restricted not user perhaps permission of friend's photo? noticed in @ least 1 case, cold "false" on photoid, logged in personal account (not knowing person @ all) see photo fine. these inconsistent levels of security confusing me. i way tell kind of link going before bother querying photoid or sending url on further processing. there way force field on feed or there field contains data i'm not seeing? its not made clear facebook. unfortunately, because don't h...

i've got custom values in appsettings, in web.config file. these values checked upon every request. (please ignore fact might bad/good thing .. that's out of scope of question). eg. so if every request checks web.config file value of key, be smart put application cache (eg. via global.asax) instead of checking value every request? i'm assuming when read value appsettings, website physical read of web.config file? or information read memory when website starts , references appsettings information inmemory read .. not disk i/o read? the webconfig cached. @ first request of website physical read. others requests use cache data. why when change web.config file , call request site have little delay, because information in web.config being recached.

i understand where 1 = '1' returns true, , where 222 = convert(varchar, 222) return true in t-sql. but, when working in, can test_expression , subquery of different datatypes? example can test_expression int, , subquery varchar? they can be: datatypes cast highest based on " datatype precedence " rules. logically, x in (a,b,c) x=a or x=b or x=c of course. relevant contrived case using scalar values. really don't know if values cast float (the highest here) before comparison ( ..in.. ) or cast per comparison ( ..or..or.. ) where cast(1 int) in ('1', cast(1.0 float), 1.0 /*decimal*/) for subquery in in clause, column has data type cast per scalar rules edit, after comment: all datatypes implicitly cast select top 1 * sys.columns 1 in (select cast('1' char(1)) sys.columns) or declare @intvar int = 1, @charvar char(1) = '1'; select top 1 * sys.columns @intvar in (select @charvar sys.columns) ...
