angularjs - htm5mode with parameters doesn't work for me - the first hand, code: config app: promoapp.config(['$routeprovider','$locationprovider',function($routeprovider,$locationprovider){ $locationprovider.html5mode(true); $routeprovider. when('/home',{ templateurl: 'views/home.html', controller: 'homecontroller' }). when('/web',{ templateurl: 'views/web.html', controller: 'webcontroller' }). when('/portfolio',{ templateurl: 'views/portfolio.html' }). when('/game',{ templateurl: 'views/game.html' }). when('/contact',{ templateurl: 'views/contact.html', controller: 'contactcontroller' }). when('/admin',{ templateurl: 'views/admin.ht

julia find in matrix with (row,col) instead of index - in julia can find coordinates of elements in matrix via: julia> find( x -> x == 2, [ 1 2 3; 2 3 4; 1 0 2] ) 3-element array{int64,1}: 2 4 9 these values right prefer (row,col) tuples instead. (1,2) (2,1) (3,3) what easiest way accomplish in julia? i don't believe there inbuilt way it, here function it function findmat(f, a::abstractmatrix) m,n = size(a) out = (int,int)[] in 1:m, j in 1:n f(a[i,j]) && push!(out,(i,j)) end out end e.g. julia> findmat(x->x==2, [ 1 2 3; 2 3 4; 1 0 2] ) 3-element array{(int64,int64),1}: (1,2) (2,1) (3,3) if big number of items satisfy status might more efficient in 2 passes, uncertainty it. matrix find julia-lang

pass vectors by pointer and reference in c++ - a quick question how safely pass , utilize vectors in c++. i know when using vectors have careful addresses them , elements because when dynamically alter size may alter address (unless utilize reserve etc. i'm imagining not know how much space need). now want pass existing vector (created elsewhere) function adapts , changes size etc. i'm little unclear safe because accomplish of pointers. on top of there using references vector , muddies water me. for instance take 2 next functions , comments in them void function1(std::vector<int>* vec){ std::cout<<"the size of vector is: "<<vec->size()<<std::endl; //presumably valid here (int i=0;i<10;i++){ (*vec).pushback(i); //is safe? or fail? // or: vec->pushback(i); difference? } std::cout<<"the size of vector is: "<<vec->size()<<std::endl; //is line valid he

Multi-windows R graphs in C# with RDotNet - i have c# code simple windows form 3 buttons. button 1 calls r , plots surface while button 2 plots contour. if launch application , click on button 1, correctly see surface plot click on button 2 open new window counter plot. unfortunately, if seek app freezes , cannot go on. have added button 3 intention close r engine if running. thought kill r instance , reopen when clicking on button 2. doesn't work either. there way prepare problem? using system; using system.collections.generic; using system.componentmodel; using system.data; using system.drawing; using system.linq; using system.text; using system.threading.tasks; using system.windows.forms; using rdotnet; namespace mysurface { public partial class form1 : form { public form1() { initializecomponent(); } public void button1_click(object sender, eventargs e) { string dllpath = @"c:\program files\r\r-3.1.0\bin\i386\";

haskell - Evaluating lambda expressions on the form lambda x E - i got problem trying evaluate lambda expressions on form lambda x e. after hours of thinking came nil yet, there here point me abit in right direction? this should returning function argument x, can used on body e. function can thought of anonymous function on form \x -> e. variables can used in e, exist when function made(lexical scope). i should back upwards evaluation of function calls on form f a. evaluating list ( f ... ) when f not special atom, successful when either f evaluates function, or list has 2 elements ( f ) , evaluating of function f argument succeeds , gives legitimate value, mean number of function. the code i've got far handle cases leading following: type context = [( string, int )] type memory = [( int, ast )] eval::ast -> context -> memory -> ( ast, context, memory ) eval (number x) con mem = ( number x, con, mem )

c++ - Make custom type "tie-able" (compatible with std::tie) - consider have custom type (which can extend): struct foo { int a; string b; }; how can create instance of object assignable std::tie , i.e. std::tuple of references? foo foo = ...; int a; string b; std::tie(a, b) = foo; failed attempts: overloading assignment operator tuple<int&,string&> = foo not possible, since assignment operator 1 of binary operators have members of left hand side object. so tried solve implementing suitable tuple-conversion operator. next versions fail: operator tuple<int,string>() const operator tuple<const int&,const string&>() const they result in error @ assignment, telling " operator = not overloaded tuple<int&,string&> = foo ". guess because "conversion type x + deducing template parameter x operator=" don't work together, 1 of them @ once. imperfect attempt: hence trie

parsing - Read/parse a ABNF grammar with tags in C++ from a file - i have file contains abnf grammar tags in simplified example: $name = bertha {userid=013} | bob {userid=429} | ( ben | benjamin ) {userid=265}; $greet = hi | hello | greetings; $s = $greet $name; now task obtain userid parsing given sentence grammar. example, parsing sentence greetings bob should give userid 429. grammars have read in @ runtime because can alter between runs. my approach following: parse grammar 1 or multiple trees, putting tags @ leaves or nodes belong to parse sentence this/those tree(s) build tree creates given sentence(i'm thinking using earley this) use tree obtain tags (unlike in example, there multiple different tags in such tree) my question is, there software components can utilize or @ to the lowest degree modify solve task? steps 1 , 2 seem quite generic (1. reading abnf grammar c++ internal representation (e.g. trees); 2. early-algorithm (or that) working i

python - What exactly does Spyder do to Unicode strings? - running python in standard gnu terminal emulator on ubuntu 14.04, expected behavior when typing interactively: >>> len('tiθ') 4 >>> len(u'tiθ') 3 the same thing happens when running explicitly utf8-encoded script in spyder: # -*- coding: utf-8 -*- print(len('tiθ')) print(len(u'tiθ')) ...gives next output, regardless of whether run in new dedicated interpreter, or run in spyder-default interpreter (shown here): >>> runfile('/home/dan/desktop/mwe.py', wdir=r'/home/dan/desktop') 4 3 but when typing interactively in python console within spyder: >>> len('tiθ') 4 >>> len(u'tiθ') 4 this issue has been brought elsewhere, question regards differences between windows , linux. here, i'm getting different results in different consoles on same system, , python startup message in terminal emulator ,

python - Pandas - consecutive values must be different - i want subsample rows of dataframe such pairs of consecutive values in given column different, if 2 of them same, keep, say, first one. here example p = [1,1,2,1,3,3,2,4,3] t = range(len(p)) df = pd.dataframe({'t':t, 'p':p}) df p t 0 1 0 1 1 1 2 2 2 3 1 3 4 3 4 5 3 5 6 2 6 7 4 7 8 3 8 desireddf p t 0 1 0 2 2 2 3 1 3 4 3 4 6 2 6 7 4 7 8 3 8 in desireddf, 2 consecutive values in p column different. how this? >>> df[df.p != df.p.shift()] p t 0 1 0 2 2 2 3 1 3 4 3 4 6 2 6 7 4 7 8 3 8 explanation: df.p.shift() shifts entries of column p downwards row. df.p != df.p.shift() checks each entry of df.p different previous entry, returning boolean value. this method works on columns number of consecutive entries: e.g. if there run of 3 identical values, first value in run returned. python pandas dataframes distinct-
