💭 'Fuzzy Logic Inferencing in Security Applications' with Raymond Garcia
2023-03-16 18:00 - 20:00 | Iffy Books (319 N. 11th St.), 319 N. 11th St. #2I, Philadelphia, PA, 19107, United States
The next Trashpanda Village meetup is Thursday, March 16th at 6:00 p.m. See you there!
Fuzzy Logic Inferencing in Security Applications
Fuzzy Logic has been around since the 1960’s. There is an open standard for a fuzzy control language, several libraries exist that ease the implementation of applications, and its use is (sometimes unwittingly) necessary in situations where human expertise does not have closed-form expressions for metrics that have “degrees of membership” (think secure vs “very” secure, small vs “really” small, etc.). Since the 1960’s, the uses of fuzzy logic include areas of automatic control, quality control, industrial processes, investment strategies, component testing, pattern recognition, and classification. Applications of information assurance soon followed in multi-level secure database access, network security assessments, threat detection, and risk analysis to name a few.
What this presentation aims to achieve via illustrative examples and demonstrations is to inform the audience on fuzzy logic & inferencing in its application to security.
About the Presenter: Raymond Garcia, Ph.D.
Ray is experienced as both an applied researcher and a practitioner in the public sector and across several areas in the private sector that include the telecommunications, pharmaceutical, and banking industries. Within these industries, Ray has used a variety of technologies in applying natural language processing, numerical techniques, and machine learning to subject matters that include insider threat, information assurance, and situational awareness.
Ray has a BS (Temple U.), ME (Penn State), and Ph.D. (Georgia Tech) in Electrical Engineering with a minor in Applied Mathematics.

💾🌾 Permacomputing Meetup
2023-03-19 13:00 - 15:00 | Iffy Books (319 N. 11th St.), 319 N. 11th St. #2I, Philadelphia, PA, 19107, United States
Our March permacomputing meetup is on Sunday, 3/19 at 1:00 PM EST. You can join us in person at Iffy Books (319 N. 11th St. #2I, PHL) or via Jitsi audio stream.
➡️ Jitsi Stream Link
From Permacomputing.net:
Permacomputing is a more sustainable approach to computer and network technology inspired by permaculture. Permacomputing is both a concept and a community of practice oriented around issues of resilience and regenerativity in digital technology.
In a time where computing epitomizes industrial waste, permacomputing encourages a more sustainable approach, maximizing hardware lifespans, minimizing energy use and focussing on the use of already available computational resources. We do this because humans are part of nature and technology is an extension of humans, and we acknowledge that technology has been used to harm nature. We want to find out how we can practice good relations with the Earth by learning from ecological systems to leverage and re-center existing technologies and practices. We are also interested in investigating what a permacomputing way of life could be, and what sort of transformative computational culture and aesthetics it could bring forward.
If you want to know more, please start reading about what is permacomputing in essence, and then dive into its principles.

We’re hosting a virtual meetup on Tuesday, April 11th at 7 p.m. to help Meshtastic users across Philly get connected. Our goal is to make a wireless chat network across the PHL area using low-power LoRa radios.

To join the Meshtastic chat, you’ll need a LoRa radio such as a Heltec LoRa32, LILYGO LoRa32, or LILYGO T-Beam. Here’s a full list of compatible devices. If you don’t have a LoRa radio, you’re still welcome to join the meetup.
Here are a few things we’re hoping to accomplish:
• Flash the latest stable Meshtastic firmware, version 2.1.5.23272da.
• Decide on a channel setting (e.g., Long Range Fast or Very Long Range Slow).
• Discuss Meshtastic device roles (client, router, router client, etc.).
• Set up a shared encryption key.
• Chat!
Here’s our zine on LoRa + Meshtastic from summer 2022, which is now slightly out of date. We’re working on a new version.
