Return index of greatest value in an array
...ax = arr[i];
}
}
return maxIndex;
}
There’s also this one-liner:
let i = arr.indexOf(Math.max(...arr));
It performs twice as many comparisons as necessary and will throw a RangeError on large arrays, though. I’d stick to the function.

What is a stack trace, and how can I use it to debug my application errors?
...etBookIds(Author.java:36)

What's different about this one is the "Caused by". Sometimes exceptions will have multiple "Caused by" sections. For these, you typically want to find the "root cause", which will be one of the lowest "Caused by" sections in the stack trace. In our cas...
Visual Studio 2013 IntelliSense stops working for ASP.NET MVC5 Controllers
...me, surprisingly often in VS Express, and occasionally in VS Professional. One thing I noticed in Pro, is that it has happened after unexpected shut downs (when IT forces a reboot in the middle of the night). So it may be related to Visual Studio not closing correctly. The technique described above ...
Are static variables shared between threads?
...model and how writes become visible to threads. You can't count on changes one thread makes becoming visible to other threads in a timely manner (actually the JVM has no obligation to make those changes visible to you at all, in any time frame), unless you establish a happens-before relationship.

Why not write it yourself? It's a one-liner or such:

from fractions import Fraction
def nCk(n,k):
return int( reduce(mul, (Fraction(n-i, i+1) for i in range(k)), 1) )

In Matlab, when is it optimal to use bsxfun?
...called "singleton expasion". As an aside, the singleton dimensions are the ones that will be dropped if you call squeeze.
It is possible that for very small problems, the repmat approach is faster - but at that array size, both operations are so fast that it likely won't make any difference in term...
Pass all variables from one shell script to another?

If the assignment does not precede a utility name in the command, or if the assignment is a result of the operatio...
Is it true that one should not use NSLog() on production code?

Safest way to convert float to integer in python?
...e more, the number is padded with zeroes on the right.
It follows that 53 ones is the largest number that can be stored without padding. Naturally, all (integer) numbers requiring less digits can be stored accurately.
Adding one to 111(omitted)111 (53 ones) yields 100...000, (53 zeroes). As we kno...
