Profile picture: truncated screenshot of a WINE error message. The error message is titled "Download failed". The message reads "Download Failed: Success. Check your connection and click 'Retry' to try downloading the files again, or click 'Next' to continue installing anyway." There is only one button labeled "OK".

I post about planes and ATC stuff. A lot.
Pretty unfiltered, thoughts/opinions my own not my employers. Probably overanalyzing things... Or am I? What does that really mean? Maybe if I calculate the optimal amount of analysis...

@[email protected]Internally known as "novaTopFlex" throughout the Fediverse and the proprietary-verse alike, I am an aspiring prospective Linux enthusiast who is also interested in information security concepts, including, but not limited to, the various cybersecurity applications and applets that may exist for our benefit. I am gradually gaining new interests, both for the purposes of computer science and for cybersecurity. Although I am primarily focused on the computer science perspectives, I often switch between desktop environments as necessary and perform cybersecurity work under stress and under significant organizational strategy.

It's not for fun, or any sense of community.
It's just trying to dull the pain.
I have friends everywhere.
