If the connection between you to your computer is severed, then your device will lock, shutdown, or shred its encryption keys -- thus keeping your encrypted data safe from thieves that steal your device.
What is DEF CON?
DEF CON is a yearly hacker conference in Las Vegas, USA.

Talk Description
BusKill is a Dead Man Switch triggered when a magnetic breakaway is tripped, severing a USB connection. I’ve written OpenSCAD code that creates a 3D printable file for plastic parts needed to create the magnetic breakaway. Should anyone need to adjust this design for variations of components, the code is parameterized allowing for easy customization. To assemble a BusKill Dead Man Switch cord you will need:
- a usb-a extension cord,
- a usb hard drive capable of being attached to a carabiner,
- a carabiner,
- the plastic pieces in this file,
- a usb female port,
- a usb male,
- 4 magnets,
- 4 pogo pins,
- 4 pogo receptors,
- wire,
- 8 screws,
- and BusKill software.

Full BOM, glossary, and assembly instructions are included in the github repository. The room holds approx. 70 attendees seated. I’ll be delivering 3 x 30 min presentations – with some tailoring to what sort of audience I get each time.
Meet Me @ DEF CON
If you'd like to find me and chat, I'm also planning to attend:

- Hacker Kareoke (Friday and Sat 20:00-21:00 \| 222),
- Goth Night (Friday: 21:00 – 02:00 \| 322-324),
- QueerCon Mixer (Saturday: 16:00-18:00 \| Chillout 2),
- EFF Trivia (Saturday: 17:30-21:30 \| 307-308), and
- Jack Rysider’s Masquerade (Saturday: 21:00 – 01:00 \| 325-327)

By attending DEF CON, I hope to make connections and find collaborators. I hope during the demo labs to find people who will bring fresh ideas to the project to make it more effective.
- Gov agency asking me for an “unaltered copy” of ~15 or so e-mails (HTML!)
I received several machine-generate e-mails which are all mostly the same: a notification. They are HTML emails with no plaintext MIME part. Yikes! And to complicate matters further, the messages traversed my anonaddy forwarding account which PGP encrypts every message to me before forwarding it to my normal email account.
The gov wants me to give them an “unaltered copy” of these e-mails. This gov office actually blocks my mail server so I am generally unwilling to send them email. This means I will be giving them the emails on paper hardcopy.
So wtf, this is tricky. They want an “unaltered copy”. If I were to print the MBOX files, it would be useless to them because it’s a base64 blob that only I can decrypt. My mail client is mutt so the HTML is detected and piped through w3m to give me a text version that is readable enough.
But in general, how do you give unaltered copies of an HTML email on paper form? This is not necessarily for a court but it could go down that path. Would a court want to see raw HTML tags? Or do courts prefer the HTML to be rendered for readability?
Normally I copy the w3m-rendered text of email into LaTeX and typeset it to look pretty and copy-paste the useful headers into a well-styled header in a monospaced font. And I omit the useless headers. But I get the impression my way of working would not pass for “unaltered”.
I could perhaps try to feed the HTML into
wkhtmltopdf
. In the end, HTML rendering always varies depending on the rendering tool. Normies use MS Outlook, and I have to figure that the gov is normally dealing with normies. So maybe I should install Evolution or Thunderbird. Any suggestions for a tool that is particularly good at making HTML email presentable on paper without looking too custom?#askFedi

Another great video from 13 cubed. These commands took me back, way back lol. I also learned that there are 'newer' versions of the commands I am most familiar with.

I'm new to the field - I was software developer before. I'm curious if there are any cool resources (podcasts, newsletters, etc) that you follow and can recommend! :)
