For an academic, he sure is an idiot. Here's a quick little bit of advice: never put all of your work in one basket and for GOD sake, make backups. After that, make a backup of that back up -store it off site. Don't be this guy. If you have some brilliant recant, don't @ me. I don't care to hear it.

Interesting, I went back to X so that I may be able to chat it up with friends there.... but it is clear Elon Musk is very much censoring aany view other than his own. Fuck ICE, Fuck Trump, and FUCK the USA (at the moment, at least).

I found a simple #hack for perusing a #news website and not get drawn in to their BS..... just scroll down to the bottom. That's it, nothing else. The first items on their homepage are slop.... designed to create division and improve their ratings. Scroll WAAAaaAAAAy down. The interesting stuff!!

I hate #politics... and politicians TBH... but Sen. Kennedy just called dRumps Greenland threats "weapons-grade stupid". You gotta hand it to Kennedy, he really can throw around words with a hilarious touch.

I think my expectations of #humanity are confirmed. Even on #socialmedia, I'm alone. #Cancer killed my parents, mom recently. Christmas, Easter, Thanksgivings, birthdays are spent alone now. so I reach out to SOCIAL media and... crickets. I've never felt so out of place. Well, #merrychristmas anyway

The average auto vehicle has more #code that an F-35? More than a 777. CAN Bus and ICS (MODBUS, etc) isn't a pretty or flashy #cybersecurity theatre to play in. It takes dedication to studying without injecting ego. You wont win a prize, you'll save lives.

Hmm, whats the possibility that this is a propaganda pyramid scheme. Putin has something on Trump, then Trump has something on Kennedy and Gabbard, and the scheme goes on and on. The USA got what it deserves, really. Vote stupidly, get stupid results. The USA is quite compromised by foreign actors.

During the pandemic, China promised more vaccine support to Guatemala if they left Taiwan as an alley and grouped up with Beijing. #China is relentless in pressuring countries, specifically in Latin countries, to delegitimize Taipei. Bravo, Beijing. You’ve mastered the art of the bully.

I often wonder if the public at large know how vulnerable their shiny new cars are. Now imagine an army of hacked eSIMs in burner phones travelling on heavily populated highways, ready to deploy #malware to access the CAN bus of cars in proximity. Sounds like a good book.

Spending time on “X” lately… could easily see yeeting that shit to the moon and beyond. Maybe put it in the boot of that Tesla and initiate a self destruct sequence. Why do #infosec people stay? I think it’s ego. Followers, hear me roar.

Why are SSH keys better than passwords for authentication under #Linux ??
Because trying to brute-force a good SSH key is like trying to find a specific grain of sand on all the world's beaches... while blindfolded... and the beaches are on different planets 😂

I just played on stage with Victor Wooten and his brothers tonight. Holy hell, that was nerve wracking. As my solo came up, he’s like “y’all need Moore bass?” Lolol everybody needs more bass!
