Hello. I need to ask about my folders. My 26,263 folders became 'date modified' in 8 minutes. I created those folders and I am aware they stood there. I think any human being can't be so quick. It seems that this is a good news bad news scenerio, and the only good reason I can think of for...

I understand everything except operational security. What is that trying to say?

I'm impressed by this article. https://arstechnica.com/information-technology/2021/10/securing-your-digital-life-part-2/ It discusses more than just choosing passwords and more than Internet security.. Do you disagree with the article? Do you have additional security tips that you use?

I have a quick query. When I'm applying to jobs related to math and physics (software engineer, data analyst, data scientist, python developer, quantitative analyst, programmer, research analyst, etc), I am seeing a good portion of them requiring a security clearance. Is this something others...

OFFICIAL SOLUTION: d=e^(-1) mod 160=107 mp= c^(d) mod p=7 mq:=c^(d) mod q=7 MY THOUGHTS: I understand how d = 107, but I got that by using m = (17-1)(11-1) = 160. What I don't understand is the next two lines (from the official solution). I am aware of the P = C^d mod n (decryption) formula...
