00:31:44 James Newton: Great to see you all today!
00:32:15 Melissa Chhaunkar: Hi! This is my first time back since 2019!
00:40:11 James Newton: I don’t think I know any other groups that /might/ be excited about this, but there is a new algo for shortest path:
https://arxiv.org/pdf/2504.17033
“We give a deterministic O(m log2/3 n)-time algorithm for single-source shortest paths (SSSP) on
directed graphs with real non-negative edge weights in the comparison-addition model. This is the first
result to break the O(m + n log n) time bound of Dijkstra’s algorithm on sparse graphs, showing that
Dijkstra’s algorithm is not optimal for SSSP”
00:48:26 James Newton: Hackaday Supercon is coming the first weekend in November. Mostly electronics, but a lot of robotics. In Pasadena CA, so it’s a schlep for PNW people, but well worth it in my opinion.
00:52:35 James Newton: My writing on robotics Ethics, Dangers, etc…

00:53:40 Lloyd: Seattle GNU/Linux Conference: Nov. 7-8, https://seagl.org
01:00:41 James Newton: Everything the bean counters allow you to do…
01:25:09 James Newton: Am I allowed to plug the robotics class I teach for UCSD Extension? It’s remote and async so anyone should be able to sign up if you can afford it. And it’s mostly for high school age students, so if you know anyone who wants to have a future in this world, please consider recommending it to them? Starts in a month, but it usually fills up.

01:29:05 Matthew Guo [yaepublishing.house]: Am i allowed to do a self-intro? My first meeting.
01:34:32 Connor: https://docs.google.com/presentation/d/1j-t1dXQjl6dM1JR96hBoYOJTYMvPK1ZSYIPSmEY9rm8
01:35:23 Melissa Chhaunkar: Nice to meet you, @Matthew Guo [yaepublishing.house]. I need to run for now but feel free to add me on LinkedIn www.linkedin.com/in/melissa-chhaunkar
01:36:24 Matthew Guo [yaepublishing.house]: Thanks!
01:48:36 Steven Kaehler: cryptography vs. cryptology?
01:49:25 Craig Austin: Did you suggest I should toss my TP-Link Port switches and replace them with another brand?
02:12:48 Steven Kaehler: Does using the same initial seed produce the same sequence of pseudo random numbers?
02:14:28 James Newton: @Craig Austin it’s a really interesting question. I looked up TP-Link
https://www.cvedetails.com/vendor/11936
vs e.g. Cisco
https://www.cvedetails.com/vendor/16
Who has 10x more products, and 4x more vulnerabilities. But I don’t know if that’s a fair comparison.
02:14:40 James Newton: @Steven Kaehler yes. Exactly that.
02:16:34 James Newton: It’s used in video games (e.g. “No Mans Sky”) to have MASSIVE simulated universes which are consistent down to the individual details without having to store any data. Each solar system is based on a seed related to it’s location, and they unpack details based on the pseudo random details.
02:26:26 James Newton: the random design of random number generators…
02:31:10 James Newton: Don’t commit it to github. :cough:

02:47:20 Lloyd: Have to drop – great talk! Thanks!

02:49:54 James Newton: Reacted to “Have to drop – gre…” with 👋

02:51:32 Keith: you mean APRS, need to be a ham for that..
