The current beta version of MathJax 2.6 implements a new renderer that is faster and can be rendered on the server side:
Improved CommonHTML output. The CommonHTML output now provides the
same layout quality and MathML support as the HTML-CSS and SVG output.
It is on average 40% faster th...

Don't tell anyone, but I've nicked my uncle's time travel machine! My uncle is obsessed with prime numbers though, and that shows in the machine - he has programmed it so that it can only go to dates that sum up to a prime number.
So it can't go to 1947-08-15 because 1947+8+15 = 1970 which is n...
Write a function that takes compares each pair of adjacent items and swaps them if they are in the wrong order. The pass through the list is repeated until no swaps are needed, which indicates that the list is sorted.

Is there a way you output each partial result of the Sort function? i.e.
Sort[{2,3,1}]
{2,1,3}
{1,2,3}
The Challenge
Given a grid of numbers (10 <= N <= 99)
Return number with the highest sum of the four numbers adjacent to it; that is the numbers above, below, right, and left of the number, but not itself.
The number itself does not count, only its four neighbors.
A number on the edge can be t...
Given a string, your task is to collapse it into a zigzag-like structure as described below.
Folding into a Zigzag
We'll take the string "Mississippi" as an example:
First, output the longest prefix consisting of unique characters only:

Write code that when given a positive number \$x\$ as input, outputs the largest positive divisor of \$x\$ less than or equal to the square root of \$x\$.
In other words find the largest \$n\$ such that
\$\exists m>0:(m\cdot n=x)\land(m\geq n)\$
For example if the input were \$12\$ the divis...
