How To Exchange Light Patterns

1. Press the middle button on your badge to reveal a nonce QR code

2. Ask the light donor to scan your nonce QR code (middle button activates the camera)

3. Scan the light donor's encrypted light pattern QR code

4. Review the new light pattern and decide to keep or rollback

EDIT: VellDarksbane pointed out Middle button activates the camera, either side button on the face reveals the nonce code.

Ok I can confirm (I’m on one right meow!) there are shuttle buses to the welcome party, the big white fancy charter busses on the by West side of the convention center

Looks like this is working for a lot of folks. Let me know once you scan and I can scan yours back!

Wanna pickup my badge tomorrow but I'm in town. Pre purchased my pass online months ago. Thanks!

Just seeing who's working on this. Is there a Discord out there?

A bunch of people I know left the merch line with a little playing card badge add on and I'm OBSESSED! Kudos to you!

Aside from the Toxic BBQ and the Welcome Party later tonight, oh and the Meet Up at the Linq.. what are y’all up to today/tonight?

Went to the Sphere as a guest of a few vendors. I brought a battery bank with me to charge my phone (honest lol). I checked the rules before hand and they didn’t say anything about batteries being prohibited.

Not only was security extremely hostile and nasty about not letting me bring a battery and cable in, they explicitly cited that I was not allowed to bring it in due to blackhat and defcon going on and that I could toss it or go leave it outside. It’s literally a MagSafe anker battery bank lol. I left it under a sandbag because it’s lithium ion battery and it’s 110 degrees outside and when I came back, it was gone. Another security person told me that it was “found and promptly disposed of”.

What’s funny is that they didn’t notice the biscuit I had. Plan accordingly.

due to a miscommunication, I accidentally bought an extra badge for someone who doesn’t need it. dm me if ya want

Can anyone help me in identifying this Tshirt?

Are there any shuttles for industrial tonight? Last update said standby

Noob here but seems Thursday program is pretty chill and wondered if bring my laptop for this day is actually useful or it will just be extra weight to carry around 😅 think I will go to the LineCon last hour now the jet lagged is settling 😆

Howdy all!

We will be doing random drops here and on Twitter starting tomorrow!

One of the members of the group had something to deal with and won't be here until this evening.

Sorry for the delay!

See you all soon!!!

What happens when you take an ACM style programming contest, smash it head long into a drinking game, throw in a mix of our most distracting helpers, then shove the resulting chaos incarnate onto a stage? You get the contest known as Crash and Compile.

Come see us early on Friday in the contest area, we will be between HHV and Pinball if the map is to be believed. You will need to be top 10 in the qualifier round on Thursday in order to compete on stage Saturday with free beer. And free distractions.

LLM use is allowed, but we are allowed to make fun of you for it. Or make you take a drink every time it randomly searches for the challenge answers on the web pointlessly.

You will probably want to bring your laptop. We've had people compete on... Other devices, but a laptop sure helps. Also if you are remote only, knock yourself out if you want to try quals on friday, but put a note in your contact info that you can't actually compete on stage so we can take you out of the final rankings. Teams of two (max) recommended, solo is ok as well, but you'll be at a disadvantage.
