Question
You are trying to get a screw to get into a thread. It won't start. How do you get the screw into the hole you are trying to screw-in?
Answer
Are the screws slightly too big? Did other screws come with the item you are working with? It could be that the screws are not the right ones. Sometimes there are hidden screws in a package or the wrong screws are in package (from a mistaken from the manufacturer).
Problem scenario
You are logged into an e-commerce website or a utility website. When you click log out, the page refreshes. You never really log out (as you are logged back in automatically). What are you doing wrong?
Possible Solution
Close the web browser that does not log you out. Try a different web browser (e.g., use Firefox if a different web browser had the problem). A different web browser may help; it may allow you to log out consistently.

Question scenario
You have read about doxing or doxxing. What does it mean?
Answer
Doxing is the act of publicizing via the internet previously cloaked data about an individual or an organization. It is the unmasking of a formerly anonymous person to identify the target with an embarassing fact or allegation. Controversially connecting a person to something humiliating on a website is doxing. It can be illegal in certain circumstances.
Here are other excerpts:
"...doxing is the act of revealing someone’s sensitive information online. Hackers use doxing to harass, threaten, or get revenge on others." (Taken from https://www.avast.com/c-what-is-doxxing.)
"The term 'Doxing' is short for "dropping dox" 'dox' being slang for documents. Typically, doxing is a malicious act, used against people with whom the hacker disagrees or dislikes." (Taken from https://www.kaspersky.com/resource-center/definitions/what-is-doxing.)
"The term doxxing (sometimes spelled doxing) is a longtime hacker term derived from “dropping dox” or documents about an adversary. Motivations range from personal revenge to political ends. " (Taken from https://www.usnews.com/360-reviews/privacy/what-is-doxxing.)
"Doxing is a form of cyberbullying that uses sensitive or secret information, statements, or records for the harassment, exposure, financial harm, or other exploitation of targeted individuals." (Taken from https://www.fortinet.com/resources/cyberglossary/doxing.)

Problem scenario
You bought new weightlifting shoes. They seem to tight. They are not comfortable. What should you do?
Possible Solution #1
If only one shoe feels too tight, can you see if the tongue is double-up or folded on one side? By flattening it or unravelling it, that may help.
Possible Solution #2
Can you make the velcro strap connect without as much force and tightness?
Possible Solution #3
Loosening the strap(s) or re-tying your shoes in a looser way may help. If it is the first time you have worn weightlifting shoes, there is a good chance they are the right size. Sometimes you may need to buy a bigger size. We think you should try finding a balance between support and comfort. You may need to wear them for a couple weeks to realize that that is how they are supposed to feel.
Possible Solution #4
You could try a two-strap shoe which can distribute the support better in a more contoured way.
