Catching error codes in a shell pipe
...
You can also check the ${PIPESTATUS[]} array after the full execution, e.g. if you run:
./a | ./b | ./c
Then ${PIPESTATUS} will be an array of error codes from each command in the pipe, so if the middle command failed, echo ${PIPESTATUS[@]} would contain someth...

What is data oriented design?
...on you should do this is that if data used together are placed in separate arrays, there is a risk that they will compete for the same slots in the cache. Thus loading one will throw out the other.
So compared to Object Oriented programming, the classes you end up making are not related to the ent...
How much is the overhead of smart pointers compared to normal pointers in C++?
...? This depends on your implementation. Let's say you are iterating over an array of 3 phases, each phase has an array of 1024 elements. Creating a smart_ptr for this process might be overkill, since once the iteration is done you'll know you have to erase it. So you could gain extra memory from not ...
Pure JavaScript equivalent of jQuery's $.ready() - how to call a function when the page/DOM is ready
...we have, do nothing. If we haven't yet been called, then loop through the array of ready functions and call each one in the order they were added. Set a flag to indicate these have all been called so they are never executed more than once.
Clear the function array so any closures they might be usi...

What is the difference between a reference type and value type in c#?
...t. If PO boxes doesn't do it for you, try a hashtable or dictionary or an array or something similar.
Thus, when you do something like:
var a = "Hello";
the computer will do the following:
allocate memory (say starting at memory location 1000 for 5 bytes) and put H (at 1000), e (at 1001), l (...
Realistic usage of the C99 'restrict' keyword?
...vectors of numbers in memory, and I have the following code:
void MultiplyArrays(int* dest, int* src1, int* src2, int n)
{
for(int i = 0; i < n; i++)
{
dest[i] = src1[i]*src2[i];
}
}
The compiler needs to properly handle if dest, src1, and src2 overlap, meaning it must do o...
Why is a combiner needed for reduce method that converts type in java 8
...type and finish with the same type.
You can achieve this with
String res = Arrays.asList("one", "two","three","four")
.stream()
.reduce("",
(accumulatedStr, str) -> accumulatedStr + str); //accumulator
and this helps you to visualize what's happening:
The accumu...
