Below, is a description of a sequence:
0.1, 0.01, 0.001, 0.0001, 0.00001, and so on, until reaching 0. {one hundred zeros} 1
Total so far: 101 terms.
Then, continued:
0.2, 0.02, 0.002, 0.0002, 0.00002, and so on, until reaching 0. {two hundred zeros} 2
Total so far: 101 + 201 = 302 terms....

Rationalise the Denominator
code-golf math
Challenge
Given a fraction with a surd as the denominator, output the rationalised fraction.
Rationalising the Denominator
To rationalise the denominator, what you have to do is take the fraction and make one which is equal which does not have an ir...
This fractal looks relatively simple, but how would you generate it?
On a smaller scale:
I made it using a 1D cellular automaton with a four cell neighborhood:
..|-|.. 2 generations back
|-||-||-| 1 generation back
..|-|.. current generation
But since there are $65536$ possib...
QI (Quite Interesting) is a British comedy panel game television quiz show created and co-produced by John Lloyd, hosted by Stephen Fry (replaced by Sandi Toksvig after the M series), and featuring permanent panelist Alan Davies. Most of the questions are extremely obscure, making it unlikely that the correct answer will be given. To compensate, points are awarded not only for right answers, but also for interesting ones, regardless of whether they are right or even relate to the original question. Conversely, points are deducted from a panelist who gives "answers which are not only wrong, but...
The one-looper ASCII box
Intro
I saw this one in one of my university programming textbooks as an "advanced" exercise and I thought it would fit very well here.

Task
Your program have to ask for an input number and draw a...
Sending error messages to the null device
... instead of avoiding them.
This should either be forbidden or add to the byte count, as setting options to suppress messages do.
example
We could do this with rules. It's slightly complicated because it's not a simple recursion. Consider the coloured image in the question. The green element fractals into the three blue elements. And each of the three blue elements into three orange elements. But wait there's more! A couple of...
The tag feasibility is only used in two questions, has no wiki, and the questions are both tagged restricted-sourcejavascriptfeasibility.
These questions are asked by 2 different users. Here they are:

Excel: 47 bytes.
="0."&REPT("0",MIN(ROW()*100,COLUMN()-1))&ROW()
Finally, something excel can compete at (or at least I can compete with my current skill level)
How it works:
place the formula across an entire row. it should print sequence 1.
drag it to n rows where n is your desired iterati...
I was challenged by one of my friends to solve this coding problem:
Given a non-negative number represented as an array of digits, add one to the number. The digits are stored such that the most significant digit is at the head of the list. Return the value as a new list.
This was my solution, ...

Essentially, a user's answer in Excel uses the drag-down formula feature of Excel, as described in the linked related meta question. I thought that from the highest voted answer to that question, we had, by community consensus, determined that mouse interaction is unnecessary. I personally take i...
