Will the data in fwrite() buffer be cleared when a program exists abnormally?
fwrite() is a library call that firstly buffers the data into a user space buffer, and then call the write() system call later to actually carry out the write operations. If a program invokes fwrite() to write some data to a file but then exists abnormally, will the buffer of fwrite() be cleared, or the buffered data will be left over in memory?

How many times does a number/character occurs in a string literal?
No tokenization should be necessary. Consider the following string literal:
char* string = "12, 789, 1234";
The output for this specific string would be:
0, 2, 2, 1, 1, 0, 0, 1, 1, 1
This means that there were 0 zeros, 2 ones, 2 twos, 1 three, etc.
I understand that I could use the ASCII table but I was wondering if there was an easier way of doing it.

Creating JSON-like data in Typescript
So in normal Javascript you can execute this block of code fine:
var myObj = {};
myObj['one'] = {};

Is this just by design? (e.g. I'm expected to make my own classes for this)
Should I reuse variables?
Let's say that i need a counter (I program in C), only once. Should I just reuse a variable that is no longer needed, instead of declaring a counter?
For instance:
int main() {
int in;
//code goes here
for(in=0; in<10; in++) //do something
//instead of using i, I reuse in and use it as a counter
return 0;
}

warning: format ‘%s’ expects argument of type ‘char *’, but argument 2 has type ‘int’ using argv
I don't even know what is happening, I just started a new project and setup a basic cat just to make sure everything was working, and this happened.
#include "stdlib.h"
#include "stdio.h"
int main(int argc, char *argv) {
printf("%s",argv[0]);
return 0;
}
That's it, I reinstalled gcc, g++, and both multilibs. I really have no clue what to even think.
In C, can you do this? int i; i = get_long() % 20;
unsigned long get_long(); //returns some crazy large unsigned long
int i;
i = get_long() % 20;
The value of the right hand side should ALWAYS be big enough to fit into an integer because the possible values are only {0, 1, 2 .... 18, 19}.
Can I assume that the compiler can convert that unsigned long right hand side to an integer on the left hand side?

How to know whether a pointer is in physical memory or it will trigger a Page Fault?
If I have a pointer and I care about memory access performance I may check whether the next operation on it will trigger a page fault. If it will, an algorithm could be designed so that it reorders loop operations to minimize page faults.
Is there any portable (or linux/windows non-portable) way to check for a particular memory address whether access will trigger a page fault?

Trying to understand a program in C
I'm trying to understand this kind of program in C, but I can't. Exactly, I can't figure out how *s is changed, and why the compiler shows 210012.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
void WhatIamDoing(char *s) {
char ch;
if (*s) {
ch = *s;
s++;
WhatIamDoing(s);
putchar(ch);
}
}
int main() {
char s[20] = "012" ;
WhatIamDoing(s) ;
printf( "%s", s ) ;
}

A web service for NFL schedules and scores (not api - json or xml)
I have been all over looking for a web service that supplies for free, of course, the NFL schedules/scores for 2016. Lots of answers; packages/fees/api's, but all I want is the service. Some suggested sites have disappeared or appear abandoned. What's being used out there in 2016? I prefer a json port but can deal with xml. I don't want to scrape.
Thank you for your help.
Mouse hover effect for owner drawn button without subclassing
As the title suggests, is there a way to receive in the parent window a notification of mouse hovering a button (which has been owner drawn) without the need of subclassing it? I use plain C on Windows.

JavaScript library for offline maps?
I want a JavaScript offline library for world maps that allows me to provide a city name and then locate it on the map(using lat and long that is stored in it).
I've come across amchart maps, leaflet and jVectorMap but none of them has this offline support I want. Google Maps also doesn't provide this offline support.
Can you name some JS libraries for this ?

Cannot access outside of domian folder using __DIR__
while I was using __DIR__ . '/../folder/outside_of_domain_folder/file.inc.php to access a file outside of my domain folder, an error was returned (no such file or directory) but the file does exist. But when I used it access a include file within my domain folder, __DIR__ works again. Any reasons why this happened? Or did I made some mistake in my code?
Check whether an array exists in an array of arrays?
I'm using JavaScript, and would like to check whether an array exists in an array of arrays.
Here is my code, along with the return values:
var myArr = [1,3];
var prizes = [[1,3],[1,4]];
prizes.indexOf(myArr);
-1
Why?
It's the same in jQuery:
$.inArray(myArr, prizes);
-1
Why is this returning -1 when the element is present in the array?
Primality test using Fermat little theorm
code:
void prime()
{
int i,N;
scanf("%d",&N);
for(i=2;i<N;i++)
{
if (((i^(N-1))%N )==1);
else{
printf("not prime");
return;
}
}
printf("prime");
return;
}
This program is based on Fermat's Theorem on prime numbers. N is number to be tested as prime. This program is not showing correct result for '11'. Maybe due to some mistake which is not identified by me.
Spaces inserted by the C preprocessor
Suppose we are given this input C code:
#define Y 20
#define A(x) (10+x+Y)
A(A(40))
gcc -E outputs like that (10+(10+40 +20)+20).
gcc -E -traditional-cpp outputs like that (10+(10+40+20)+20).
Why the default cpp inserts the space after 40 ?
Where can I find the most detailed specification of the cpp that covers that logic ?

Javascript - removing undefined fields from an object
Is there a clean way to remove undefined fields from an object?
i.e.
> var obj = { a: 1, b: undefined, c: 3 }
> removeUndefined(obj)
{ a: 1, c: 3 }
I came across two solutions:
_.each(query, function removeUndefined(value, key) {
if (_.isUndefined(value)) {
delete query[key];
}
});
or:
_.omit(obj, _.filter(_.keys(obj), function(key) { return _.isUndefined(obj[key]) }))

JavaScript: requestAnimateFrame get faster
I have an animation with requesetAnimationFrame And when I replay it, it gets faster and faster until it gets invisible.

if ( parseInt(currt.bottom)<700)

}
function animation (){
tirer();
requestAnimationFrame(animation);
}
How can I get it to be a stable, constant speed?
