When AWS goes down and takes half the internet with it, maybe it’s time to rethink our basket strategy.

Fishing 🎣? Grand Canyon 🏜️? Hotel room reverse-engineering 🛠️?
What would you do?

🚨 Breaking 🚨
Our 2nd Breaking BitLocker session at Black Hat got cut.
Only 3 seats left for the Aug 2–3 run. 🔥
Hands-on. Gritty. Soldering scars? likely.

Got a flat on the kid trailer.
Not just the tube - tyre was toast too. 😬

Swapped it and used my go-to fix:
the Xiaomi Portable Compressor.
🛠 Precise
♻️ Reusable
🚗 Lives in the car

Way better than CO₂ if you’ve got kids in tow.

Spent half a day chasing ghosts on the CAN bus. Logic analyzer showed traffic, but the system was dead silent.
Turns out I forgot the termination resistor — the one thing I was told to check first.
Lesson: don’t skip the basics. 🧌🔧
#CANbus #DebuggingFails #ElectronicsLife
Forgot the grill tongs at a Swiss Grillplatz.
So I built some — 2 sticks + fishing line = DIY spring-loaded BBQ tongs.
Dad Level: 💪

Most people wait.
For clarity. For courage. For the “right” time.

But the truth? You'll rarely feel ready.
Movement brings clarity. Not the other way around.

That first step changes everything.

“Why do you always carry a knife?”
My great-grandfather told my grandfather, who told my dad, who told me: “A real man always carries a knife.”

Today, I used mine to turn a normal bottle into a spill-proof straw bottle.

And that’s the difference: you’ve clearly been through Dunning-Kruger more than once - and learnt a lot each time. And you‘re surely more than just acting competent 😉
“0-day” LPE - but only works if you know the password?

That’s not a vuln. That’s literally a feature.

Tired of seeing this stuff blindly reposted by folks who can’t tell access control from exploit. We need fewer click-chasers, more professionals.
