## Ubuntu feature for writing emojis without any external application

I know Ubuntu can show emojis, but I’ve seen Windows 10 has this extra feature: you press super + . and then a window appears with emojis (and other regular characters that can’t be found on the keyboard, like the character map!), so you can select any to type it in the text you’re writing […]

## How can I edit columns of numbers in vim using conditionals?

If I have, for example, a column of numbers: 4 6 8 10 12 Is there a way in Vim that I could find all numbers higher than 8, than do math only with these numbers? Obtaining a new column as a result: 4 6 8 (10+2)=12 (12+2)=14

## Evaluating the Limit of a Sequence Defined by a Riemann Integrable Function

For example, say I have a function $f(x)$ defined from $-1$ to $1$ inclusive and it is Riemann integrable. Then, I have a sequence defined as $$\int_{\frac{-1}{n}}^{\frac{1}{n}} f(x) dx = x_n$$ How would I then evaluate the limit of $x_n$? And would there be a corresponding proof of this necessary with the computation? Thank […]

## Colon or Semicolon for ‘I’m Sorry

I was wondering whether using a colon is incorrect if I used it as follows: ’I’m sorry: I only saw your message this morning.’ My logic for using the colon rather than the semicolon is that the relation between the apology and the succeeding statement is direct. The reason why I am sorry is as […]

## Combinatorial optimization (find partitions)

A problem arose to solve the problem with a solution that became impracticable. Well, I have a set of 12 elements that represent quantities: $$\Omega = \{16, 132, 135, 135, 136, 138, 138, 139, 301, 334, 355, 361\}$$ I can join elements, get subsets, of this set such that the sum of the elements does […]
