I'm building the user-interface for an academic website using JavaScript, jQuery, and Handlebars. I have just added a new feature, which shows the user a grid of objects and allows them to arbitrarily apply a number of filters. The grid is re-rendered dynamically from a Handlebars template.

I have some code for a calculator, and I was wondering what I could look at to make the code smaller, easier to read or better in any way. I'm particularly looking at my global variable x. Is there any way to change the code to completely remove that? Someone mentioned a getTwoInputs() function, ...
Seeing as it's October, I thought I'd do the community challenge. Due to my inexperience coding in Groovy, I decided to give Groovy a go. I'm not sure how well I followed Groovy conventions, and the rendering is quite slow.

Your question would be on-topic on Code Review. However, it is also on-topic for DBA. By Stack Exchange policy, being a better fit on another site does not make it eligible for migration; only questions that are off-topic on the original site may be migrated. (Many questions are asked every da...
I have written a network chat program as my first major project in Perl. It makes simple use of REGEXP's, modules, sockets, command-line option parsing, and forking and uses these features to produce a fairly simple multi-client chat program with a basic nickname system.

Over the past years(?) there's been a debate about the status of the optimization, performance, memory-optimization and code-size-optimization:
January 2012: Tag synonyms (optimize -> optimization)
Oct 2013: Tags for [optimization], [performance], [speed]
Oct 2014: Should we just put an end to ...
This is a sort-of-useless "utility" I wrote to learn my way around shell programming better.
It ended up being kind of long, so here's a link to a Gist containing the code: https://gist.github.com/gwerbin/71a67eb13baef89c33b1
My concerns are:
Is the code readable? Could it be more efficient, ...

I have tweaked my bottom-up mergesort so that it accepts not just raw C-arrays but also std::vector. Did not test yet, but I am confident that it can sort std::arrays also. What comes to std::list, it won't qualify for my implementation, yet it does not seem to be the...

I have programmed this alarm application in Java using JavaFX for the GUI. I'd like these questions covered in the review:
Is my code efficient? Can it be shortened?
Are there any flaws in my code?
Do I violate any OOP principles? If so, how, where and how do I rectify them?

I have written a basic Container class, which is able to hold data by key-value-pairs. The keys can be notated as an array (e. g. ['database', 'host']) or a string, which consists of individual keys concatenated by dots (e. g. 'database.host').

I've solved Project Euler #2, but solving the same in Hacker Rank which has time constraint of < 4 seconds doesn't work. I've tried using the square root solution for speeding up but it fails.
Example:
The prime factors of 10000001 are 11 and 909091, we have sqrt(10000001) = 3162, if we check ...

I'm still pretty new to JavaScript. I'm making a game to get a better understanding.

I will only address the repetition in your collision detection code in this answer.
The following lines of code are repeated several times:

var y1 = $el.offset().top;
var h1 = $el.outerHeight(true);
var w1 = $el.outerWidth(true);
var b1 = y1 + h1;
var r1 = x1 + w1;
