## sharepoint on prem – Check permissions not accurate for AD Group changes

I’ve removed a user from an AD group, though check permissions is still showing them as having permissions due to that group.

I’m aware of WindowsTokenLifetime, but that is set to 10 hours, while the check permissions is still wrong after 16 hours. Is there a different token that expires on a different schedule? At what point will check permissions show accurate data after a change in windows group membership?

This is SharePoint 2019.

## malware – Why is the term “nation state” used to refer to a government-sponsored effort in infosec, and is it accurate?

I work in infosec and as such, have read many whitepapers and been to many conference talks. I hear all the time, especially in conversation and literature about malware, the term “nation state” used to refer to a government entity or government-sponsored activity. The term “state actor” is also used.

My question is, why? According to Wikipedia:

A nation state is a state in which a great majority shares the same culture and is conscious of it. The nation state is an ideal in which cultural boundaries match up with political boundaries.1 According to one definition, “a nation state is a sovereign state of which most of its subjects are united also by factors which defined a nation such as language or common descent.” It is a more precise concept than “country”, since a country does not need to have a predominant ethnic group.

According to Merriam-Webster, the definition is:

a form of political organization under which a relatively homogeneous people inhabits a sovereign state

Is there some inherent need for the government sponsor to be primarily of one ethnic background in infosec literature? I just don’t understand why this term in particular is so frequently used, when there are many forms of states, such as a federated state, multinational state, or even more general terms such as “government” or “country,” all of whom would likely be capable of and do participate in infosec activities.

## unity – Predicted trajectory is less accurate at greater angles

I'm currently making a 2D Billiards game where the cue follows the players mouse around the ball, and when the user clicks the mouse it shoots the ball. I have a linerenderer running from the ball and it stops on whatever object it collides with. That works well, but I'm struggling with the predicted trajectory line. I have one working and it roughly shows where the ball will go, but the steeper the angle (the more side-on the shot is), the less accurate it becomes! Can anyone help me with this? Thanks.

## My first proof of linear algebra – is it accurate and written correctly?

This is the first proof exercise of "linear algebra as an introduction to abstract mathematics". This is also my first proof (apart from proving things like the properties of integers and trigonometric identities). I hope someone can criticize it and let me know what I did well or what I did wrong.

Problem: Let a, b, c and d be real numbers. Consider the system of equations (1):
$$ax_1 + bx_2 = 0$$
$$cx_1 + dx_2 = 0$$

Note that $$x_1 = x_2 = 0$$ is a solution for any choice of a, b, c and d.
Prove that, if $$ad-bc neq0$$, then $$x_1 = x_2 = 0$$ is the only solution.

Evidence: We will prove by contrapositive. Presume $$x_1 = x_2 = 0$$ is not the only solution. Presume
$$A = begin {bmatrix} a & b \ c & d end {bmatrix}, X = begin {bmatrix} x_1 \ x_2 end {bmatrix}, 0 = begin {bmatrix} 0 \ 0 end {bmatrix}$$
Then the system of equations (1) is equivalent to the expression $$AX = 0$$. For $$AX = 0$$ to be true we must have either $$A = 0$$ or $$X = 0$$. Since we assume $$x_1 = x_2 = 0$$ is not the only solution, we assume $$X neq0$$. Then for $$AX = 0$$ to be true we must have $$A = 0$$, and so, $$a = b = c = d = 0$$. Yes $$a = b = c = d = 0$$, then $$ab-cd = 0$$. $$blacksquare$$

## An accurate bulk Google indexing checker?

Currently, when you want to check the indexing of sites in Google, you have to go to Google and enter site: domain.com for each domain you want to check. If you have a large list of domains to check, it can take a long time. A mass indexing checker around?
