#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.

“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

morn, gonna find coffee

drinking coffee

morn from Berlin

on the train to Berlin after a very nice #35c3

get the feeling that Leipzig pulled out all the stops on the tramsets for #35c3 service, mixing and matching whatever worked

It worked great, not much less convenient than #Defcon at the rio

looks like the #35c3 ruby town is being garbage collected ;_;

love the seemingly-random #35c3 applause
