i have c code android lots of low-level number crunching. i'd know settings should use (e.g. android.mk , application.mk) files code produced run on current android devices takes advantage of optimisations specific chipsets. i'm looking default android.mk , application.mk settings use , want avoid having litter c code #ifdef branches. for example, i'm aware armv7 has floating point instructions , armv7 chips support neon instructions , default arm supports neither of these. possible set flags can build armv7 neon, armv7 without neon , default arm build? i'm know how latter 2 not 3. i'm cautious settings use assume current defaults safest settings , risks other options have. for gcc specific optimisation, i'm using following flags: local_cflags=-ffast-math -o3 -funroll-loops i've checked 3 of these speed code. there other common ones add? another tip have add "local_arm_mode := arm" android.mk enable speed on newer arm chips (although

i have controller called head_buses_controller.rb , in routes have mapped map.resources :head_buses this results in urls being http://domain.com/head_buses i have urls dash - instead of underscore _ . is possible have urls dashes go head_buses controller? cheers eef try use one: resources :head_buses, :as => 'head-buses'

overview of application: have delphi application allows user run queries on mysql databases on different systems, using tadoquery component retrieve data. user can retrieve data identical tables on 2 different systems (e.g. table_xyz in database_abc on system1 , system 2) running 2 separate queries, , 2 sets of data written file , manually joined on pc form 1 report. question: possible select data identical table/database on different systems 1 query? i'm pretty confident isn't possible due limitation of tadoquery's connection string having point single system, want make sure correct. i know it's possible retrieve data 2 identical tables in 2 different databases on same system using union statement, e.g.: select * database1.table_xyz union select * database2.table_xyz what need similar above example, retrieving data databases on different systems. basically, possible somehow incorporate connection string in sql statement, or connect in different way somehow

how current system's time , date without using calender.getinstance() ? try date d = new date(); charsequence s = dateformat.format("eeee, mmmm d, yyyy ", d.gettime()); you can edit format string like..

i have synchronized method in singleton class called many threads simultaneously. there java api available check thread owning lock ? you perhaps print out thread.currentthread() in synchronized method.

i want create setup requires microsoft sql server 2005 , .net framework 3.5. if software isn't installed, setup should offer user install them now. i don't know if can include either of 2 in installation package itself. however, can tell setup app check if .net framework , sql server 2005 express edition installed. if not, download , install them , continue installation of application. of course, require internet connection. these options available when right-click on setup project, select properties, , click on prerequisites button. note paddy said, sql server 2005 different story.

i developed web service works on windows using vs2005 .can run on android mobile? you cannot run web service application created visual studio on android device. can consume individual web service android application if configured on server.

for example firefoxdriver, how sending out clicks , commands firefox instance? it having webserver within webdriver addon firefox. language bindings rest-ish type call done, clicks, typing etc. you can see rest-ish interface here . call json wire protocol. have more native events via advanced user interactions api . more native clicks , typing, @ os level. each language binding takes care of dont need worry it.

in app.yaml configuration file can required login: admin . question "what" or "who" admin? in app engine console in administration -> permissions section they're talking admin . however, if add new user can choose between owner , developer , viewer . which of admin ? owner or owner + developer or three? when working users either on own apps domain or normal google users: owners can supported ui. only owners can make changes on permissions tab (invite, change role, remove). developers can except changes on permissions tab. viewers cannot change anything. everyone admin before feature went live owner. (this available since version 1.4.2) all 3 roles given admin status when application runs (i.e., users.is_current_user_admin() returns true).

i have datagridview bound array of objects. list<node> nodes = getnodelist(); m_grid.datasource = nodes; i handle selectionchanged event. in handler selectionchanged event want access selected objects. all seem able access value each cell in grid rather overall object associated row. void onselectionchanged( object sender, eventargs e ) { foreach ( dataviewgridrow row in m_grid.selectedrows ) { /* here want able access node object associated row*/ } } i'm sure must possible can't figure out. row index , array seems bit hacky. try this... datagridviewselectedrowcollection rows = mydatagridview.selectedrows; foreach (datagridviewrow row in rows) { datarow myrow = (row.databounditem datarowview).row; // datarow }

the following code outputs 'x set in class a', how make output 'x set in class b' without changing class b? <?php class { public static $x = 'x set in class a'; public static function getx() { return self::$x; } } class b extends { public static $x = 'x set in class b'; } echo b::getx(); self always refers class, defined. looking "late static binding" (as suggest, dont use). static keyword within code block refers "actual" class, means: either called class ( xy::method() ), or class of called object ( $x->method() ). return static::$x; the static keyword @ property declaration has nothing to lsb. common declartion class properties. note, lsb not available in php<5.3

this question has answer here: “text-decoration” , “:after” pseudo-element, revisited 10 answers the goal of question create code adds filetype after link (so people know whether should expect special files). there options using image, don't , prefer have file type between square brackets in different size. approach use :after pseudoclass in following way a[href$='.doc']:after, a[href$='.rtf']:after { content: " [doc]"; font-family: monospace; font-size: 60%; font-weight:bolder; color:red; position:relative; top: -0.8em; } however, gets me strange problem. content seems in block part of link. therefore link underlining continues after link under "[doc]". so question pretty straightforward: there way either in way or make sure can control under "[doc]" separately under link? try adding display: inlin

i have following: http://jsfiddle.net/oshirowanen/2vqvd/ how dynamically position .dropdown element no matter .navigation placed on screen? edit 1: for example, whereever .navigation on screen, .dropdown's top left corner should directly below bottom left corner of .navigation making single element when .navigation clicked on. here go: http://jsfiddle.net/2vqvd/2/ btw, re-factored code changing both javascript , css.

i have send email (if emails particular account automatic email saying "thanks sending"). how should in asp.net mvc 2? logic? consider using brilliant library mvcmailer you can use send text or html email, body define view. can use whatever model need , render emails specific data. it available nuget package easy install.

i'm getting 'variable undefined', i'm guessing has scope of variables in vbscript, knowledge limited this. i know loading of email addresses works , actual emailing because have checked these separately. i'm trying loop through list of email addresses , send log file each.. any additional information great! first, there var array @ top of file: dim emails() function getemailaddresses() dim objfso dim objconfigfile dim strline dim icounter const forreading = 1, forwriting = 2, forappending = 8 set objfso = createobject("scripting.filesystemobject") set objconfigfile = objfso.opentextfile("emailaddresses.config", forreading) icounter = 0 while not objconfigfile.atendofstream redim preserve emails(icounter) strline = trim(objconfigfile.readline) emails(icounter) = strline icounter = icounter + 1 loop objconfigfile.close end function function writetolo

i can't manage display unicode characters in vb.net. i'm doing in c#: string mystring = "\u03a3"; //upper case sigma (sum) but doesn't work in vb , can't find way make work. visual studio source files unicode enabled. in cases, can put unicode character want right in source. failing that, try chrw() function.

i not first 1 observe vb6 "run full compile" fast , nice (hence incremental, compile needed process) whereas make exe takes long time. way long, when have no choice test , troubleshoot behavior of executable , standalone process rather debug version running under ide process. so, there compiler option or other magic transition make fast, incremental mode compile changed modules , link them precompiled other stuff? or agonizingly slow make matter of slow linker rather module compiler? go project|properties... dialog. select compile tab. choose compile p-code. compiling native code involves 2 compiler passes , link pass. i'm not sure why seems slow unless you've never compiled large programs using other languages.

i've been trying contents of specific status using status url e.g http://twitter.com/#!/jquery/status/36102693709680640 , username associated status. in case, @jquery is there way in php and/or jquery? the best way use twitter api . must perform http request on correct uri , data returned in xml format. you'll parse xml needed data. the twitter username under the screen_name tag.

i came across embedded web server named mongoose , http://code.google.com/p/mongoose/ , read wiki great , searched sample hello world program couldn't find it... found example written in c++ windows , can 1 provide example c program run webserver.. it quite simple, first need implement call function: void *event_handler(enum mg_event event, struct mg_connection *conn) { const struct mg_request_info *request_info = mg_get_request_info(conn); static void* done = "done"; if (event == mg_new_request) { if (strcmp(request_info->uri, "/hello") == 0) { // handle c[renderer] request if(strcmp(request_info->request_method, "get") != 0) { // send error (we care http get) mg_printf(conn, "http/1.1 %d error (%s)\r\n\r\n%s", 500, "we care http get", "we care http get");

i want implement silverlight based component co-browsing. can please me started? thanks okay, first things first. i'm going assume figured out how commands "admin" "client". if not true, let me know. second: outrageously difficult thing build third: here's start ;-) to use default sl4 webbrowser component, need run application out-of-browser elevated trust. should set first. in test app, added webbrowser component , subscribed loadcompleted event. in eventhandler can use like: void webbrowser1_loadcompleted(object sender, system.windows.navigation.navigationeventargs e) { //pseudo code event update clients onadminnavigated(e.uri); } clientside use like: void adminnavigated(mycustomnavigationeventargs e) { clientbrowser.navigate(e.uri); } hope helps.

i working com objects in managed code , using new dynamic type this. works in areas can issue in others. i think how best of both worlds, flexibility of dynamic type (late bound) support say, rcw (early bound) somehow wrapping dynamic type in more manageable stucture. wondering if there preferred method (if idea) or things should consider. the 2 basic ideas came far follows: firstly, creating static class allows me call methods of dynamic type in managed way. public static class comobjectwrapper { public static void somemethod(dynamic comobject, int x) { comobject.somemethod(x); } public static bool getsomeprop(dynamic comobject) { comobject.getsomeprop(); } public static void setsomeprop(dynamic comobject, bool foo) { comobject.setsomeprop(foo); } } secondly, creating class constructed using com object, mapping members managed properties, methods, etc. public class comobjectwrapper { private dynamic comobject = null;

i have hibernate application may produce concurrent inserts , updates (via session.saveorupdate ) records same primary key, assigned . these transactions long-running, perhaps 15 seconds on average (since data collected remote sources , persisted comes in). db isolation level set read committed, , i'm using mysql , innodb. the problem scenario creates excessive lock waits timeout, either result of deadlock or long transactions. leads me few questions: does database engine release locks when transaction committed? if case, should seek shorten transactions? if so, practice use separate read , write transactions, write transaction made short , take place after of data gathered (the bulk of transaction length involves collecting remote data). edit: here's simple test approximates believe happening. since i'm dealing long running transactions, commit takes place long after first flush. illustrate situation left commit out of test: @entity static class person {

this simple decorator works expected: def protect(*permissions): def outer(f): def inner(*args): print permissions[0] return f(*args) return inner return outer @protect('protected') def func(var): return var print func('something') the output is: protected moving beyond python shell , using decorator in larger scope of project, strange happening: while inside of inner function, permissions not defined. i'm thinking there must python variable scoping/decorator subtleties i'm unaware of causing this. insights appreciated. in mind figure out going on - let me try spell out: it has python not "perceiving" "permissions" variable existing on scopes outside "inner" function - since when "inner" defined, "permissions" long have been defined in 'outsidemost' scope of protect. thus, when compiling inner variale taken being global

i kind of new f# maybe question dumb. wrote program in f# used generic types. compiler determined types not way desired because had bug in deepest function call had instantiated type wrong type. resulted in type mismatch elsewhere had used type had expected. have mention find root of problem tried explicitly enforce higher level functions use types desired generic type. type mismatch shown in high-level functions not low level function type instantiated. think it's not convenient way of determining types because easier programmers determine type on higher level functions , explicit type assignment should result in type error in lower level function type has been determined. in experience seems automatic type determination of compiler overrides explicit type declaration. understanding wrong here? something code below: type test<'a,'b>={func:'a->'b; arg:'a} let c(a)= a.func(2)|>ignore let b(a)= c(a) let a(a:test<int64,int64>)= b

i've been playing around js generated in php , far i've had no luck ie. other browsers firefox , chrome parse , execute js code. for example page http://crusthq.com/projects/crusttalk/ loads javascript http://crusthq.com/projects/crusttalk/_js/?page=demo i tried sending following headers in php script http://crusthq.com/projects/crusttalk/_js/ content-type: text/javascript , content-type: application/x-javascript , content-type: application/javascript with no luck. has idea why ie not parsing , executing js code? i used this instance of google closure compiler service attempt pretty-print javascript. it failed error: number of errors: 1 jsc_trailing_comma: parse error. internet explorer has non-standard intepretation of trailing commas. arrays have wrong length , objects not parse @ all. @ line 190 character 183 in ?page=demo ...ully",delay:4,clear:false,method:"append",xbutton:true,onclose:function(){},}

that , other information movie, width, height, duration, framerate , if make other urlrequest. i need banner management system. you maybe using external interface , let swf tell php app whats what. the swf call javascript function in page sending list of parameters interested in , pass on php. applies if swf not viral though. if have no control of swf embedded send post request name pair values (width, height etc) php page. also timwebdev says amfphp solution swf / backend communication. if had better idea of requirements might able suggest more relevant solution.

i'm learning groovy / grails, , writing first integration test. it's failing with: groovy.lang.missingmethodexception: no signature of method: com.mangofactory.scurry.user.save() applicable argument types: () values: [] my test isn't doing fancy: class usereventcontrollertests extends controllerunittestcase { protected void setup() { super.setup() } protected void teardown() { super.teardown() } void testaddingauser() { def user = new user(emailaddress: "martypitt@test.com") user.save() } } saving entity works fine when through scaffolded pages provided grails. what have missed? if want integration tests shouldn't extend 1 of unit test base classes, change to class usereventcontrollertests extends groovytestcase { ... } and make sure it's in test/integration, not test/unit. but looks want test controller (it's called usereventcontrollertests) should

i have been developing site stores spatial data in mysql database, of buildings, gardens, etc. in form of polygons (latitudes , longitudes). i want know how retrieve polygon data in mysql. i have seen sample query insert polygon data: http://amper.110mb.com/spat/mysql_initgeometry2.htm but want know how retrieve data table, based on constraints like: "where latitude < 9.33 , longitude > 22.4" how find whether point lies inside or outside of polygon here page lots of examples: http://howto-use-mysql-spatial-ext.blogspot.com/ this 1 of examples retrieve rows points intersect specified bounding box: set @bbox = 'polygon((0 0, 10 0, 10 10, 0 10, 0 0))'; select name, astext(location) points intersects( location, geomfromtext(@bbox) ); the mysql documentation says these spatial functions work geometries (looks point geometry). can check if geometry in database intersects 1 specify in select statement.

i know language specification forbids partial specialization of function template. i know rationale why forbids it? not useful? template<typename t, typename u> void f() {} //allowed! template<> void f<int, char>() {} //allowed! template<typename t> void f<char, t>() {} //not allowed! template<typename t> void f<t, int>() {} //not allowed! afaik that's changed in c++0x. i guess oversight (considering can partial specialization effect more verbose code, placing function static member of class). you might relevant dr (defect report), if there one. edit : checking this, find others have believed that, no-one able find such support in draft standard. this thread seems indicate partial specialization of function templates not supported in c++0x . edit 2 : example of meant "placing function static member of class": #include <iostream> using namespace std; // template<typ

does knows why c instruction being reordered when cin cout , gets used consecutively here? using dev-c++ 4.9.9.2. #include<iostream> using namespace std; int main(){ char a[10],b; for(;;){ cout<<"\ncin>>b:"; cin>>b; cout<<"gets(a):"; gets(a); cout<<"cout<<a<<b:"<<a<<" "<<b<<"\n\n"; } } i got output like: cin>>b:132 gets(a):cout<<a<<b:32 1 cin>>b:465 gets(a):cout<<a<<b:65 4 cin>>b:312242 gets(a):cout<<a<<b:12242 3 cin>>b:1 gets(a):cout<<a<<b: 1 cin>>b: it seemed input cin passed in gets.. , appears instructions reordered like: cin>>b; gets(a); cout<<"gets(a):"; instead of, cin>>b; cout<<"gets(a):"; gets(a); cin>>b read character, leaving rest of input read

i'm absolute beginner xcode , objective-c, hey sounded book i'm reading rory lewis ! i'm trying write simple question game ios. this first app, except few versions "hello world" ;-) have read large number of forums, , haven't yet found i'm looking for. so read out random line plain textfile, let's "file.txt" wich contains 500 lines. when press button, app fetch random line file.txt , present on screen. have tried number things, , feel i'm fumbling in dark ! hoping point me in right direction (a basic 1 please ;-). something should work: #include <stdlib.h> #include <time.h> nsstring *file = [[nsbundle mainbundle] pathforresource:@"file" oftype:@"txt"]; nsstring *filecontents = [nsstring stringwithcontentsoffile:file]; nsarray *lines = [filecontents componentsseparatedbystring:@"\n"]; /* initialize random seed: */ srand ( time(null) ); /* generate random number: */ in

i'm sorry title. seem have problem. i'm beginner , i'm sorry if asked before.. couldnt find straight answer on one. (when search class, pointer , child results passing parent or child pointers... not want pass (this) child or parent pointer, want pass pointer initialized on child class.. parent). i'm trying here better explained code: class app { public: virtual void init(void) { window = &basicwindow(); } virtual void createwindow(void) { window->create(); } protected: window *window; }; class game : public app { public: virtual void init(void) { window = &openglwindow(); } }; int main () { app *game = &game(); game->init(); game->createwindow(); return 0; } is legal? have abstract window class basicwindow , openglwindow derives. however, when create window access violation reading location error breaking @ window->create() inside app::createwindow() function. thanks i&

can give example of how string can returned call using win32::api() function? need return string , print using $val . please give example if same can handled using pointer return type. use win32::api; $res = new win32::api('abc.dll','myfun','_argument type list_','_return type list_')or die $^e; $val= $res->call(); print ($val); the documentation win32::api 's call() method suggests must pass call() scalar used buffer store returned value; call() return whether call succeeded or not. example: my $return_buffer = " " x 80; if ($res->call(80, $return_buffer)) { print "ok, api call returned '$return_buffer'\n"; } else { print "the api call failed reason.\n"; } edit: quoting the docs completeness: the 2 parameters needed here length of buffer hold returned temporary path, , pointer buffer itself. numerical parameters, can use either constant expression or variable,

is there way check libraries running process using? to more specific, if program loads shared libraries using dlopen , readelf or ldd not going show it. possible @ information running process? if yes, how? other people on right track. here couple ways. cat /proc/nnnn/maps | awk '{print $6}' | grep '\.so' | sort | uniq or, strace: strace cmd.... 2>&1 | grep '^open(".*\.so"' both of these assume shared libraries have ".so" somewhere in paths, can modify that. first 1 gives pretty output list of libraries, 1 per line. second 1 keep on listing libraries opened, that's nice. edit: , of course lsof ... lsof -p nnnn | awk '{print $9}' | grep '\.so'
