after reading freemarker documentation , googling don't see how can build test object (like associated, multilevel array) in freemarker only. so like: <#assign seq=["a","b","c"]> but in more depth - (pseudo): aa ab ac ad b ba bb bc c ca cb cc cd ce is possible in freemarker (as front-end dev waiting back-end guys finish need work on , not use bare arrays)? tnx that's not multi-level array, because each nested array has name ("a", "b", "c"). closest can think of is: <#assign foo = { "a": ["aa", "ab", "ac", "ad"], "b": ["ba", "bb", "bc"], "c": ["ca", "cb", "cc", "cd", "ce"] }> but there have utilized ftl hash literals keep key order. without that: <#assign foo = [ {"name" : "

i relatively new cuda , trying write kernel calculates sum of absolute differences between query vector , large database of vectors. elements of both must 8 bit unsigned ints. i've based kernel off nvidias sample parallel reduction kernel, i've read thread . i getting 5gb/s not better fast cpu , not come close theoretical bandwidth of ddr5 gt640 of 80gb/s. my data set consists of 1024 bytes query vector, 100,000 x 1024 bytes database i have 100,000 blocks of 128 threads, if each block accesses same 1024 byte query_vector, going cause worse performance? since every block accessing same memory location. blocksize , shared memory both set 128 , 128*sizeof(int), 128 #define'd threads_per_block template<uint blocksize> __global__ void reduction_sum_abs( byte* query_vector, byte* db_vector, uint32_t* result ) { extern __shared__ uint sum[]; uint db_linear_index = (blockidx.y*griddim.x) + blockidx.x ; uint = threadidx.x; sum[threadidx.x] = 0

can inline member initialization lambda capture , use this pointer? struct a{ int = 42; int b = [this](){ return this->a * 4; }(); }; is valid c++11 code (according specification) or gcc extension? if valid, why have use this-> when referring member a ? is valid c++11 code? no. lambdas in block scope can have capture lists: c++11 5.1.2/9 lambda-expression smallest enclosing scope block scope local lambda expression ; other lambda-expression shall not have capture-list in lambda-introducer . so seems gcc extension. (as noted in comments, open issue , might become standard 1 day.) why have use this-> while referring member a? you don't, @ least version of gcc i'm using: http://ideone.com/k857vc .

i installed eclipse , mingw on sister's computer running windows 7. while testing see if set properly, noticed won't print anything: #include<stdio.h> int main() { int x; printf("hello world!\n"); printf("enter number... \n"); scanf("%d", &x); printf("you entered %d", x); return 0; } instead, waits input, , print whole thing @ once. here's how looks: 345 hello world! enter number... entered 345 it after added call fflush(stdout) after printf("enter number... \n"); eclipse printed in right order, meaning, code: #include<stdio.h> int main() { int x; printf("hello world!\n"); printf("enter number... \n"); fflush(stdout); scanf("%d", &x); printf("you entered %d", x); return 0; } works expected. worth mentioning opened separate c++ project , tried same thing: #include<iostream> int
