## Solo mining: Stratum from pool 0 detected new block at height

I’m using ckpool which is a solo Bitcoin "pool". If I see this message

``````"Stratum from pool 0 detected new block at height"
``````

what does that mean in the context of a solo pool?

In addition, what is the significance of a "share" in a solo pool?

## bitcoin core – Regtest at height 120k took 600ms to generate a block

Just doing

``````while :
do
bitcoin-cli getblockcount
done
``````

brings regtest blockgen times up to 600ms when generating a block at the height 120k, even with all empty blocks.

I have noted down the following numbers:

``````height, gen-time
800 -> 7ms
5500 -> 18ms
11000 -> 31ms
22000 -> 65ms
37000 -> 110ms
``````

and so on.

This makes my test suite slowing down a lot, over time.
Is this something we can deal with?

Thanks!

## algorithms – having n towers, find the max and min possible height for the longest tower after d days

I have faced this problem and can’t find any similar question anywhere. Will you please help me solve it plz?
We have n towers in a row with their corresponding heights given as h1, h2, …, hn.
We can select `m` towers in a row each day and increase their height by `1`.
Now the question is what will be the max and min height for the highest tower after `d` days?
Input
Input will consist of two lines: First line includes three spaced integers `n`, `m`, and `d`.
In the following line, there are `n` spaced integers which are h1, h2, …, hn.
input constraints are: `1≤ m ≤ n ≤ 100,000` and `1 ≤ hi​,d ≤ 100,000,000`
Output
In one output line, you should print the max and min height for the highest tower after `d` days correspondingly.
Test cases

``````input #1
3 2 1
4 3 5
``````
``````output #1
6 5

``````input #2

## typography – Accessible line height for headings (h1, h2, h3, etc)

We are working on making our product’s typography WCAG accessible.

This is what MDN says regarding the line-height:

Use a minimum value of 1.5 for line-height for main paragraph content.
This will help people experiencing low vision conditions, as well as
people with cognitive concerns such as Dyslexia. If the page is zoomed
to increase the text size, using a unitless value ensures that the
line height will scale proportionately.

Technically they mention only main paragraph content “p” tag.

Our question is:

What line-height value should we use for headings and buttons?
Should we use at least “line-height: 1.5” for headings, buttons, and other text elements as well, or just for “p” tags?

Is line-height value smaller than 1.5 accessible for H1 and other headings?

## html – Why can’t I increase the height of this DIV?

I cannot for the life of me figure out what’s going on here. I want to increase the height of the DIV, the one with an id of titleStrip, but it isn’t happening. Very frustrated. Thought I had figured this kind of stuff out, but alas no Time for a break. Any help is always appreciated. All the other answers referred me to checking the height of the containing element, but in this case, the containing element already has a height. Below is the code.

## Calculating the expected height of a randomly built binary search tree

I need to calculate the expected height of a randomly built binary search tree, BST, with 4 different keys: $$x < y < z < w$$

According to Catalan numbers, there are 14 possible trees, 8 with height 3 and 6 with height 2. So let $$X$$ be a random discrete variable that holds the tree height, $$P{X=2}=frac{6}{14}=frac{3}{7}$$ and $$P{X=3}=frac{8}{14}=frac{4}{7}$$ hence $$E[X]=2cdot frac{3}{7} + 3cdotfrac{4}{7} = frac{18}{7}approx 2.571$$

But then I thought, not all the trees in Catalan numbers has the same probability of occurring as there are 24 ways to order the keys, so instead I get $$P{X=2}=frac{16}{24}=frac{2}{3}$$ and $$P{X=3}=frac{8}{24}=frac{1}{3}$$ and $$E[X]=2cdot frac{2}{3} + 3cdotfrac{1}{3} = frac{4}{3} + 1 = frac{7}{3} approx 2.333$$

I’m not sure which way is the correct way to calculate the probability of the possible values for $$X$$
