i'm using eclipse ide c++ project, , love tell me given symbol defined , parameters function. however, there's catch: use lazy c++ , tool takes single source file , generates .h , .cpp files. .lzz files headers, tool supports mild syntactic benefits, combining nested namespaces qualified name. additionally, has special tags tell tool put (in header or in source file). so typical sourcefile.lzz looks this: $hdr #include <iosfwd> #include "projecta/baseclass.h" $end $src #include <iostream> #include "projectb/otherclass.h" $end // forward declarations namespace bigscope::projectb { class otherclass; } namespace bigscope::projecta { class myclass : public projecta::baseclass { void somemethod(const projectb::otherclass& foo) { } } } as see, it's still recognizable c++, few extras. for reason, cdt's indexer not seem want index anything, , don't know what's wrong. in indexer view, shows me empty tree, t...

the following code in python takes long run. (i couldn't wait until program ended, though friend told me him took 20 minutes.) but equivalent code in java runs in approximately 8 seconds , in c takes 45 seconds. i expected python slow not much, , in case of c expected faster java slower. jvm using loop unrolling technique achieve speed? there reason python being slow? import time st=time.time() in xrange(0,100000): j in xrange(0,100000): continue; print "time taken : ",time.time()-st gcc 4.2 -o1 flag or higher optimize away loop , program takes 1 milli second execute. benchmark not representative far real world use. you're doing nested loop reason, , never leave empty. python doesn't optimize away loop, although see no technical reason why couldn't. python slower c because it's further machine language. xrange nice abstraction adds heavy layer of machine code compared simple c loop. c source: int main( void ){ ...

what opinion regarding project try take code , split threads automatically(maybe compile time, in runtime). take @ code below: for(int i=0;i<100;i++) sum1 += rand(100) for(int j=0;j<100;j++) sum2 += rand(100)/2 this kind of code can automatically split 2 different threads run in parallel. think it's possible? have feeling theoretically it's impossible (it reminds me halting problem) can't justify thought. do think it's useful project? there it? whether it's possible in general case know whether piece of code can parallelized not matter, because if algorithm cannot detect cases can parallelized, maybe can detect of them. that not mean useful. consider following: first of all, @ compile-time, have inspect code paths can potentially reach inside construct want parallelize. may tricky computations. second, have somehow decide parallelizable , not. cannot trivially break loop modifies same state several threads, example. difficult t...

i'm trying safely update home directory specified in /etc/passwd , standard linux utils - usermod , vipw - doing aren't provided cygwin. could tell me how changed in cygwin? edit: recent versions of cygwin (1.7.34 , beyond), see this newer question . like sblundy's answer, can edit by-hand. but if want "official" way, use cygwin-specific mkpasswd command. below snippet official docs on mkpasswd : for example, command: example 3.11. using alternate home root $ mkpasswd -l -p "$(cygpath -h)" > /etc/passwd would put local users' home directories in windows 'profiles' directory. there's bunch of other useful commands described on cygwin utilities documentation page (which includes mkpasswd ). use of cygpath in example above of these cygwin-specific tools. while you're @ it, want read using cygwin windows documentation. there's bunch of advice.

i have .net 3.5 website uploading files sql server 2008 filestream. works great until hit file size , unexpectedly odd error returns in browser. in ie 7, if upload file size of 100 meg, browser returns after 2 minutes error saying "internet explorer cannot display webpage". generic , totally useless error. timeout issue, expect see error little more explanation. in firefox 3.6.7, when uploading same file browser returns after 4 minutes equally generic , useless error says "the connection reset". again, timeout error (eg - somewhere in code have connection timing out) @ least expect firefox return after 2 minutes generic error, because ie returned after 2 minutes. i need ideas on how diagnose , track down causing problem. also, have file upload size limited 1 gig in web.config. <!-- 1 gig upload --> <httpruntime maxrequestlength="1048576" /> edit: are there settings in iis 7 affecting this? i'm not iis guru, may have config...

in c program (p1), how launch dynamically constructed command (and arguments) reads standard input p1's standard output? note that: a method other stdout --> stdin piping ok provided portable across windows , linux. i cannot use c++, java, perl, ruby, python, etc here. also, have mingw dependency windows build? reopened : question below answers linux, question wants portable method. execute program within c program the microsoft c runtime calls _popen instead of popen , appears have same functionality in windows (for console applications) , linux.

i want remove controller name url (for 1 specific controller). example: http://mydomain.com/mycontroller/myaction i want url changed to: http://mydomain.com/myaction how go doing in mvc? using mvc2 if helps me in anyway. you should map new route in global.asax (add before default one), example: routes.maproute("specificroute", "{action}/{id}", new {controller = "mycontroller", action = "index", id = urlparameter.optional}); // default route routes.maproute("default", "{controller}/{action}/{id}", new {controller = "home", action = "index", id = urlparameter.optional} );

i noticed generic ienumerator<t> inherits idisposable, non-generic interface ienumerator not. why designed in way? usually, use foreach statement go through ienumerator<t> instance. generated code of foreach has try-finally block invokes dispose() in finally. basically oversight. in c# 1.0, foreach never called dispose 1 . c# 1.2 (introduced in vs2003 - there's no 1.1, bizarrely) foreach began check in finally block whether or not iterator implemented idisposable - had way, because retrospectively making ienumerator extend idisposable have broken everyone's implementation of ienumerator . if they'd worked out it's useful foreach dispose of iterators in first place, i'm sure ienumerator have extended idisposable . when c# 2.0 , .net 2.0 came out, however, had fresh opportunity - new interface, new inheritance. makes more sense have interface extend idisposable don't need execution-time check in block, , compiler knows if ...

what's efficient way of getting value of serial column after insert statement? i.e. looking way replicate @@identity or scope_identity functionality of ms sql the value of last serial insert stored in sqlca record, second entry in sqlerrd array. brian's answer correct esql/c, haven't mentioned language you're using. if you're writing stored procedure, value can found thus: let new_id = dbinfo('sqlca.sqlerrd1'); it can found in $sth->{ix_sqlerrd}[1] if using dbi there variants other languages/interfaces, i'm sure you'll idea.

i'm trying use < c-a> ( ctrl + a ) shorcut under vim increment variable under cursor. works fine under vim running on linux. when try in gvim under windows "selects all" (i.e. highlights or visually selects text in current window). how can change behaviour or alternatively how can recover increment variable functionality (e.g. perhaps different key mapping)? this because of mswin.vim sourced default _vimrc generated when install vim. override _vimrc .vimrc using under *nix, or delete mswin.vim.

how list of ip addresses devices connected same subnet using java? this should work when hosts on network react icmp packages (ping) (>jdk 5): public void checkhosts(string subnet){ int timeout=1000; (int i=1;i<255;i++){ string host=subnet + "." + i; if (inetaddress.getbyname(host).isreachable(timeout)){ system.out.println(host + " reachable"); } } } invoke method subnet (192.168.0.1-254) this: checkhosts("192.168.0"); didnt test should work kinda this. checks 254 hosts in last byte of ip address... check: http://download-llnw.oracle.com/javase/6/docs/api/java/net/inetaddress.html#isreachable%28int%29 http://blog.taragana.com/index.php/archive/how-to-do-icmp-ping-in-java-jdk-15-and-above/ hope helped

i trying have 1 one layer, , center images within. i.e., if have 3 images , want 3 links beneath them, there way without using separate div tag each link , image? automatically make links centered under images, , images spaced evenly within layer? i wondering how make div show behind standard html if possible. i.e. if have text , div on text, div default show on text, when behind. possible using layer? yes, you'll have put container element, such div, around each image , caption keep them together. <div class="picturebox"> <div> <img /> caption caption </div> <div> <img /> more caption </div> </div> -------- .picturebox div { text-align: center; /* whatever width/height/positioning want */ } for second part of question, regarding putting behind other text, take @ css z-index , though think applies absolutely positioned elements.
