Had burritos, swapped culture stories, and ended up singing “Stairway to Heaven” with a room full of Java devs. Not your average @jugnoord.bsky.social night.
Shout-out to @rijosam.com & @hanno.codes for the laughs, lessons, and live music. 💙🎸

I used to think the best reason to attend a conference was for the talks—until I met this guy and saw his incredible photos. 📸

None of the achievements I've ever had would have been possible without you, @ancythomas.bsky.social. You're my greatest supporter, my toughest critic. Thank you for everything!
Special thanks to @ddoutsiopoulos.bsky.social for perfectly capturing her in the moment as she captured me.

A few years ago, my confidence in encryption and cryptography was shaken by an issue with a pseudorandom number generator (PRNG). An unintentional mistake in choosing a blocking algorithm resulted in timeouts for many customers.
