Prepping for this weekend's project

Additionally, its not difficult to quietly attach a device to the NMEA2000 bus (especially as staff). Something like this (NOT USED IN THIS INSTANCE) which provided my team with WIFI access to ship's network using a RaspberryPI. Ideally you'd want to use a dark enclosure and tape :D

Works like a charm

I think I'm addicted to webhooks. Ever start a long task, I mean full UDP scan long and want to be updated when its done.

Boom, make a simple script that calls a webhook with a basic message and add it to the end of the process.

I have a raspberry pi that I use for performing active eavesdropping attacks among other things. Sometimes the configuration changes and I need to know what has changed so I can change it back.

This weekend I created a script to at least tell me the current state of the configuration.

Sometimes I think about changing my handle...

This weekend I created an automation to alert my wife when printer's ink cartridge is low

#vericoban now has data for the runners to steal!

The current working title for the cyberpunk game I'm working on is.... vericoban

Added command shortening, so you can save your keyboard! Also, added the ability to supply a password that you learned from a friend, or just try to manually brute force it yourself. But trust me, the brute program is way more efficient at it.

Netrunner game now has some basic commands. Once I get a password, I'm able to move around the level. Both brute forcing and using the password raises the network's alert level.

My sources of inspiration include the NetRunner BBS door game, and multiple card games, the Johnny Mneumonic movie, as well as various Cyberpunk novels.

Created a simple level generator

Screengrab of the early CLI interface. I'm not using an engine. Just started with a simple input-loop.

Practicing prompt injection against this game gandalf.lakera.ai/gandalf

I was able to knock it out in an hour. I'm still not sure if it was that the levels were simple, or that I got teh mad skillz. Either way, it was fun to have some practice. Perhaps I'll try their other games. #promptInjection

This is why I never code in C++

Had a #meshtastic flyover recently. Sadly I wasn't monitoring chat at the time.

Here are screenshots of the #hackrf mayhem bug I was referring to. The left pic is a non-buggy feed with a range of 21Mhz. On the right is a buggy feed with a range of 20Mhz. This is not an artifact of using the web remote but mirrors what I'm seeing on the actual device.

Working on decoding the #signal from a car #keyfob using #gnuradio. The keep 1 for N block is a hack and I probably need to replace it with a proper clock detector and bit slicer, but visually it works.

Is this like the phone version of "two turntables and a microphone"?

Discovered this interesting #art piece made from various #computer parts into a form that looks like it should be functional. Too old to be Cyberpunk, to new to be any other *punk aesthetic. I think I'll call it #ewastepunk

Found this interesting double antenna setup in a #hospital. I think the horizontal polarization is to help reception with mobile devices that aren't always vertical, but no clue what system it's for.
