Opsec Warrior 

An individual described as an "OPSEC Warrior" is someone dedicated to ensuring operational security, and their focus would be on preventing the compromise of sensitive information, protecting against unauthorized access, and generally maintaining the confidentiality and integrity of operational activities. This role may involve risk assessment, implementing security measures, educating others on security best practices, and actively monitoring for potential threats.

bad opsec 

A hacker's failure to practice operational security (OPSEC), leading to exposure of personally identifying information. Common mistakes include using personal information in emails that you use for black hat activity, leaving financial paper trails, not hiding your IP address properly through services like TOR and Tails, not using encryption technology such as cryptocurrency and PGP encryption -- and most importantly, failure to shut the fuck up.

Typical outcomes for a cybercriminal practicing bad opsec include getting doxed, extorted, ratted on, or worse, arrested and indicted by the federal police.

Back when I lived in upstate new york 

A meaningless, unimpressive, self-serving introduction. An indicator that the story about to be shared will be pointless and dumb.
Back when I lived in upstate new york, I also had to park on the street - on two occasions, we got enough snow, mixed with just the right plowing, that my car was lifted off the ground from so much snow being jammed underneath it.

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.

Me: Woah! TLDU!
