How can I stay safe when I’m visiting potentially harmful websites on Android 9.0+ or similar MIUI?

I mean harmful by the fact that they might have ads, popups or other ways in which they might transfer malware to my phone or exploit vulnerabilities. And by visiting I mean interacting, clicking on items found on them, playing videos on them, like adult sites for an example of such a website.

Is there a sandbox or a VM on such Android phone that might help? Or am I secured if I have a basic antivirus, NoScript and an adblocker? Is there any you would recommend?

Thread titles disappear from “New Posts” after visiting them

When I go to New Posts and click on a thread title, that thread title will not be there if I click on the New Posts button again.

I've also noticed that it only happens to one page threads. Threads that have more than one page do not disappear UNLESS you click on the last page instead of the thread title. Then if you click on the New Posts button again it will be gone from the list.

Is it a feature or a bug?

PS I believe thread titles should just stay in the list after a user visits them.

Number of unique visitors staying 30 seconds or more + visiting 2 or more pages

I’ve been asked to report a number based on the number of unique visitors that stay more than 30 seconds AND visit two or more pages.

My plan was to create a custom report or a segment based on these criteria but in both cases I run in to the same problem; pages per session is a metric in Analytics which means I can’t use it as a filter. (at least in standard Google Analyics).

Am I missing something here? These seem like pretty basic variables.

Looking for researches or case studies on How to move users from engaging / visiting social media to website

Are there any resources, articles, research documents or case studies explains how companies or apps succeed to move users from social media to their website?

On other words: create motivation and building a transitional road map from social media to website

example: Instagram account sells goods, and want to move to e-commerce website but currently exploring opportunities how to do that (fear of the idea that its business is currently based on being a social-based store)

context: I’m currently on secondary research for UX project and I want to explore this specific area in order to get some assumptions to be validated.

What to do after visiting unsafe site

I’m sorry if this isn’t the place to ask this, but there doesn’t seem to be a web security stack exchange site, so this looks like the closest thing to me. If there’s a better place to put this question please let me know.

I’m using Firefox on Ubuntu and I accidentally clicked an ad that took me to an obvious scam site. There’s no changed behavior on my computer, but just to be safe I’d like to know what you should do after visiting an unsafe site. Thanks

For what applications of the traveling salesman problem, does visiting each city at most once truely matter?

Traditionally, the traveling salesman problem has you visit a city at least once and at most once.

However, if you were an actual traveling salesman, you would want the least cost route to visit each city at least once, and you wouldn’t be bothered visiting a city 2, 3, or more times. For given city, you might stop and hawk your wares only once, and on subsequent visits, only drive through the city without stopping.

Consider an undirected graph having a city incident to exactly two edges. The cost on one of these edges is only 10 units, while the cost on the other is 99,999,999,999. If you insist on visiting each city at most once, then you are forced to incur the cost of the high cost edge. However, if you allow yourself to visit cities multiple times, then you simply leave the way you came in (on the low cost edge). The low cost edge leads you back to a city you’ve passed through before.

The traveling salesman problem is highly contrived for an actual traveling salesman. I want to give students an application for which there’s a real incentive to visit each city at most once. For what applications is visiting each city a critical aspect of the problem?
