Is .NET/Mono or Java the better choice for cross-platform development? [closed]
...ts parts of the CLR spec that even Microsoft does not support (like 64 bit arrays). One of the most exciting new pieces of technology in the .NET world is Rosylyn. Mono has offered the C# compiler as a service for many years. Some of what Rosylyn offers is available via NRefractory as well. An examp...
var functionName = function() {} vs function functionName() {}
...n, i) => n * i);
console.log(b.join(", ")); // 0, 2, 6
(Remember that Array#map passes the entry as the first argument, and the index as the second.)
In both cases, the body of the function is just an expression; the function's return value will automatically be the result of that expression (...

O(nlogn) Algorithm - Find three evenly spaced ones within binary string
...mber of zeroes and ones, not the count of ones (which could be given as an array, like [1,5,9,15]). Checking if a set has an arithmetic progression, terms of number of 1's, is hard, and according to that paper as of 1999 no faster algorithm than O(n2) is known, and is conjectured that it doesn't exi...
Understanding typedefs for function pointers in C
...signal number because the same function is used for both.
Then I create an array of structures, where each element identifies a signal number and the handler to be installed for that signal. I've chosen to worry about 3 signals; I'd often worry about SIGHUP, SIGPIPE and SIGTERM too and about whethe...
How are strings passed in .NET?
...t. You can't do strLocal[3] = 'H' in C# like you could with a C-style char array; you have to construct a whole new string instead. The only way to change strLocal is to point the reference at another string, and that means nothing you do to strLocal can affect strMain. The value is immutable, and t...
“Single-page” JS websites and SEO
...u may have to use an uncompiled template on the client, looping through an array of users to build a list. The view re-renders every time a user's model changes. How would you do that without duplicating the templates (and not asking the server to render the view for the client)?

How to deal with SettingWithCopyWarning in Pandas?
...ence is that iloc expects either
integers/positions for index or a numpy array of boolean values, and
integer/position indexes for the columns.
For example,
df.loc[df.A > 5, 'B'] = 4
Can be written nas
df.iloc[(df.A > 5).values, 1] = 4
And,
df.loc[1, 'A'] = 100

Javascript object Vs JSON
...A JavaScript object on the other hand is a physical type. Just like a PHP array, a C++ class/ struct, a JavaScript object is an type internal to JavaScript.
