i went through link to track gps co-ordinates of current location user walks xamarin.forms app (ios platforms) but not find how it, born new xamarin.forms, can in xamarin.forms or should create xamarin ios project? any links/tutorials track user location through xamarin.forms ios platfomrs appreciated, in advance. we used xamarin-forms-labs this. works perfect xamarin.forms on platforms. for more information: geolocator

i have installed clang in machine (ubuntu) in order find memory leaks in c code. wrote sample code in order check working of follows: /* file: hello.c leak detection */ #include <stdio.h> #include <stdlib.h> void *x; int main() { x = malloc(2); x = 0; // memory leak return 0; } i found options in internet compile like $ scan-build clang --analyze hello.c and $ scan-build clang -fsanitize=address hello.c but none of them showing signs of memory leak. scan-build: using '/usr/bin/clang' static analysis scan-build: removing directory '/tmp/scan-build-2015-07-02-122717-16928-1' because contains no reports. scan-build: no bugs found. can kindly tell how correctly use clang memory leak detection. interestingly, clang static analyzer finds memory leak if declare void *x inside main : int main() { void *x = malloc(2); x = 0; // memory leak return 0; } analyzing code running: scan-build clang -g hello.c giv...

based on gradle docs , define external jars means adding build.gradle following snippet (considering have {project_root}/libs/foo.jar) in place: dependencies { runtime files('libs/foo.jar') } however, using same dependency declaration *.war files doesn't work. possible? project i'm trying depend on builds war file. since war layout different jar file standard layout, it's not possible declare war dependency file java project. possible ideas: clone project , define dependency (very stupid idea, i'm ashamed suggest sth that) contact author , ask him/her if can copy class need use. if can copy class along credits. contact author , ask him/her if make sense make codec open source (i know right now) , release standalone jar library (maybe along other classes used in project).

i've been trying figure out how perform simple entropy calculation using 4 thrust device vectors. i have 4 device vectors, representing 2 key-value pairs. first pair of vectors contains keys , number of times key appears. second pair contains keys paired bins calculating entropy. in second vector pair, keys appear multiple times, each instance representing different bin. it looks this: device vector pair 1 keyval 6 8 9 counts 1 3 2 device vector pair 2 keyval 6 8 8 9 9 binval 1 1 2 1 1 result vector (contains calculated entropy results) keyval 8 entropy 0.602 what i'm planning on doing use first vector pair check if key appears enough times calculate entropy. if count large enough, second vector pair used calculate entropy bin values key. need use of bin values particular key. example, if wanted calculate entropy keys have appeared @ least 3 times, find in first vector pair keyval 8 ready. then, search second pair instances of keyval 8, , ...

i trying implement game of sprouts using python , networkx library. idea of game start 2 vertices. player draws edge 1 vertex another. new node placed on newly created edge. rest of game's details aren't necessary placed link @ bottom further explain it. currently, first create node, add edge starting node new node. next, add edge new node terminating node. question is, there easier way of accomplishing this? instance, drawing edge first , placing new node on edge. http://nrich.maths.org/2413 it seems can use add_path() function. example: >>> g = nx.graph() >>> g.add_nodes_from( [0,1] ) >>> g.nodes() [0, 1] # have 2 nodes, 0 edges. # user clicks 2 vertices, 0 , 1. # add 1 more node first. >>> g.add_node(2) # add new edges >>> g.add_path([0,2,1]) >>> g.nodes() [0, 1, 2] >>> g.edges() [(0, 2), (1, 2)]

given pointer array of char, possible construct std::vector or boost::array it, , avoiding memory copying? thanks in advance! because vectors own own allocators , storage alike, there no way (for non primitive elements construction move_iterator s bit). so assuming goal true std::vector<char>& existing storage, you'll never succeed, not custom allocators¹. if want string, can use boost::string_ref (in utility/string_ref.hpp ). otherwise, use 1-dimensional multi_array_ref (from boost multi array) 1. using string_ref this easiest: live on coliru #include <boost/utility/string_ref.hpp> #include <iostream> using boost::string_ref; int main() { char some_arr[] = "hello world"; string_ref no_copy(some_arr); std::cout << no_copy; } 2. multi_array_ref this more versatile, , works "better" if not geared towards string interface. live on coliru #include <boost/multi_array/multi_array...
