Argh. Don't flush your IP tables over SSH if you're working from home 🤦♂️.

Space is no longer the final frontier—it’s the newest operational domain of warfare. China’s orbital “kill mesh” makes it a critical and mostly unobserved battlespace. Civilian space observers matter now more than ever. #SpaceWarfare #OSINT #SatTracking.

#meshtastic is a beautiful thing. Solar node installed on Box Mountain this weekend by yours truly. Station G2 and 8 dB gain antenna. I can get it up higher if someone wants to donate money for a rigger.

I once had co-worker read me the riot act for not verifying every single character of a program's checksum after I loaded it. I had only glanced at few bytes. I know he was operationally correct (aerospace system) but damnit, I was probabilistically correct.

But if you search really hard for the rest of your life, even with a super computer, you'll probably never find anything meaningful. You might as well just be generating random numbers.

That means that if you assign a numeric value to each letter of the alphabet, everything that has ever been written or will be written is contained somewhere within this constant.

Did you know? The Copeland-Erdős constant is formed by concatenating all prime numbers: 0.235711131719… 🧮 It’s proven to be normal in base 10, meaning every possible digit sequence eventually appears! #MathFacts #NumberTheory.

Nobody is prepared for electromagnetic space warfare. We will all wake up surprised one day.

The Pentagon needs to organize and equip itself better to protect its space assets from electronic warfare, or EW, experts say.

Some upgrades this year. Mounted the tracker to a trailer, added M2 LEO pack, plus GPS and auto leveling/declination adjustment.
