2024 Toxic BBQ September 21st!

Written by  on July 12, 2024

Hello hackers!

We have exciting news: The 2024 DC612 Toxic BBQ is on!

Big thank-you to Marie for purchasing the permit this year!

  • When: Saturday, September 21st from 4PM to 10PM Central
  • Where: Minnehaha Falls Regional Park, Wabun Picnic Shelter F (map here)
  • What:
    • Food! Bring food and we will grill it, or just show up and eat.
    • Hackers! We have been told there may be hackers in attendance.
    • Music? Games? Prizes? Stickers? Whatever you bring!
    • Beeeeeees! Due to budget cuts, we will not be providing bees this year.
  • Cost: Zero dollars!

This is a group-led event, so it is only as good as we make it. We have a sign-up sheet here to track what everyone is bringing, please fill it out if you plan on bringing stuff. Please note that canned beer is allowed, but no other alcohol per permit rules We are waiting to hear back on the alcohol front. We always need food, but paper plates, plastic utensils, and napkins never go out of style. If someone wants to bring musical entertainment, or games, or a vulnerable WiFi spot, all the better!

Nobody is required to bring anything or pay anything to attend and eat, but keep in mind that our official budget is also zero dollars, so we will only have what we all contribute.

This will be our fourth year running:

  • 2021 at the Lauderdale Community Park
  • 2022 and 2023 at Minnehaha Falls Picnic Area

and we’re hopeful to keep this tradition going for even longer.

See you all there!

* My calculations for the distance are as follows:

On Google Maps, I zoomed in as close as I could to get the best picture of the two sites. The scale on the bottom right shows that 20 feet are represented by 117 (113 + 2 on each side) pixels:

I used Greenshot to measure the distance between the two sites and found that they were 99x by 672y pixels apart. Some quick math:

99 / 117 = .846 * 20ft = 16.9 ft West

672 / 117 = 5.744 * 20ft = 114.9 ft North

The straight-line distance can be solved thanks to our friend Pythagoras and ChatGPT:

So they are 116.14 feet apart.

As to the compass direction, a 32-point compass will define 7 points between North and West:

According again to ChatGPT (I am not awake enough to math this myself) you can use the following calculations to get the angle from North:

Since each point in a 32-point compass represents 11.25 degrees, that would put us at NbW, or “North-by-West”, since 8.39 is less than 11.25 but greater than the halfway point between North and NbW (11.25 / 2 = 5.625).

So when I said “100 feet North” earlier, I apologize if I offended any sailors or land surveyors who may have expected a little more precision.


Thursday, July 11th – 6:12pm @ Discord

Hello Hackers!

This month we are joined by Ryan O’Horo (@redteamwrangler) who will be presenting his talk “Reverse Engineering an ALPR Ecosystem”:

I took a very serious interest in a specific type of ALPR [Automatic License Plate Recognition] camera, tens of thousands installed in cities across the US (including Minneapolis), recording every passing vehicle 24/7. I know where they are, what they do, how they’re sold, and how they’re broken.

I’m an artist and security engineer.

Meeting will be on Discord. If you need an invite, look no further.

Talk starts at 6:12 PM U.S. Central, but feel free to hop in early and chat.
