aot requires "component-relative" template urls i'm not sure what's meant this. can here provide additional insight on this? here's example of how ng2 app structured: ng2 => components test-component.ts => templates test.component.html the template referenced within component this: @component({ selector: 'test', templateurl: '../../ng2/templates/test.component.html' }) is example of proper component-relative template url or need change in way in order support aot? if i'm referencing template url in appropriate way what's common scenario in templateurl structure work jit not aot?

this question has answer here: what purpose of java's unary plus operator? 7 answers i in java1 semester, , asked teacher question, not answer, because didn't know why. or rather couldn't think of purpose serve. let that, when setting variables a=5 , b=-4 . , wanted know value of a+b set system.out.println . i a + b , a + + b , means add positive b . although b negative positive variable still negative 4. however, if change equation a - - b , should come out b being positive 4. so question, purpose of creating equation positive variable if positive variable, variable. since opposite valid (adding negative such + - b) sign plus doesnt affects value.

someone mentioned in irc, google doesn't have answer. "slicing" assign object of derived class instance of base class, thereby losing part of information - of "sliced" away. for example, class { int foo; }; class b : public { int bar; }; so object of type b has 2 data members, foo , bar . then if write this: b b; a = b; then information in b member bar lost in a .

in following example, taking local memory space in function "add"? , if not, parameter variables stored in memory? void add(int *a, int *b, int *result){ *result = *a + *b; } int main(){ int = 1, b = 2, result; add(&a, &b, &result); printf("result = %d\n", result); return 0; } do function parameters take local memory space? in following example, taking local memory space in function "add"? the answer these questions depends heavily upon implementation. perhaps implementation automatically inlines functions , , function parameters might eliminated entirely inlining process. implementation might hoist of runtime logic compile time ; i.e. entire example can optimised puts("result = 2"); during compilation. alternatively... where parameter variables stored in memory? often times, arguments stored register storage. register storage committed program, , might otherwise committed , u...

this question has answer here: normalize small probabilities in python 2 answers i have list of probabilities follows probability_list = [0.9, 0.8, 0.0, 0.2, 1.0] each value represents probability of appearing given word. e.g., 0.9 -> denotes probability of appearing word_1 0.9 e.g., 0.8 -> denotes probability of appearing word_2 0.8 , on. now want re-scale aforementioned probability_list way sum of becomes 1 . please suggest me suitable approach this. the easiest way sum of list , divide each element list comphrension: total = sum(probability_list) probability_list = [i/total in probability_list]
