#introductions

I'm Vito, I helped run DEF CON CTF from 2013-2017 as part of Legitimate Business Syndicate.

I like computer festivals, coffee, basic electronics, and CTF games of course.

finally re-hung my badge collection at my new place, the black badge from 2017 really pops

it was p. Cool

be real cool if someone paid me to go to DEF CON beijing again

"safety third" is a cute catchphrase I guess but it's bad and harmful

like yeah when it's a YouTube doing something obviously dangerous and short-sighted sure yuk it up

but now industrialists[1] and their toadies[2] are using "safety third" and you shouldn't trust them

1: “That’s our other rule,” Musk continues. “Safety third. There’s not even a Rule Number Two. But even though there’s nothing in second place, safety is not getting promoted to number two.” https://www.rollingstone.com/culture/culture-features/elon-musk-the-architect-of-tomorrow-120850/

I love that "*hacker voice* I'm in" feeling when I agent-forward my local ssh auth sock to another machine, scp something from there, and see the light on my (physical) ssh key blink when it auths

my first #shmoocon was really good, hope to see everyone again soon!

“Pot of Coffee || GTFO”

elixir's `String.valid?/1` that checks if a string is utf-8 only is cute

comments mine
```
# check the tail if the head is utf-8
def valid?(<<_::utf8, t::binary>>), do: valid?(t)
# we're at the end, definitely utf-8
def valid?(<<>>), do: true
# head wasn't utf-8 and we're not at the end, definitely not utf-8
def valid?(_), do: false
```

glad I skilled up in binaries in the #35c3 ctf, solving problems I didn't attempt beforehand

On the way home from an amazing #35c3 and a wonderful time with friends in Berlin.

Thanks everyone who made it a great trip for me, with special thanks for Eat Sleep Pwn Repeat for running two CTF games (one that I did really well in), the Milliways crew for having a nice space to just meet up with people and mess with displays, and of course all the 35C3 angels & staff for making it all work.

<3 vito

got coffee and apple strudel
