@caseyjohnellis @HillHackers Sorry I missed this. Conflicted with graduation events. Next year…
Had the same issues with StubHub at F1. They said there were no replacement tickets available despite the fact tickets were for sale on their platform 3 seats away from our original seats. We had already travelled to Montreal for the race and tickets got cancelled day before. Tickets should be delivered as soon as they are available to the seller. Felt like such a scam platform, especially with all the lying that no replacement tickets were available.
It’s happening! #SLEUTHCON

Many years ago when folks were living their lives in Second Life and World of Warcraft, I predicted the emergence of gaming retirement style communities where you get a place to sleep and shower and you would be served meals while you spend the rest of your time living in games. youtube.com/watch?v=9v6LWn…
@JohnHultquist @HackingDave Have mine doing alerting and enrichment around OSINT and raw intel subscriptions and it is super useful.
The window between vulnerability disclosure and real-world exploitation keeps shrinking. The Zero Day Clock visualizes how fast attackers are operationalizing new CVEs. What used to take months now often happens in days, or hours. The future needs to be Secure by Design. zerodayclock.com #AppSec #CyberSecurity
We are in a new era and most people don’t yet understand.
Everyone today is a hacker in a sense but there are very few OG hackers on which shoulders we stand Oh dude, Felix “FX” Lindner you were so much a hackers hacker and you will be missed RIP my friend and thank you
Interesting, but no surprise after the Lex podcast.
Peter Steinberger is joining OpenAI to drive the next generation of personal agents. He is a genius with a lot of amazing ideas about the future of very smart agents interacting with each other to do very useful things for people. We expect this will quickly become core to our
@DisruptiveBytes Agree, but my notes to self can be interesting and folks naturally make mistakes which made me realize I should prioritize on getting Signal set up. :-)
I'm imagining the intelligence operation that focuses on collecting all the Telegram traffic being generated by OpenClaw bots.
In an age where dynamic national security mission requirements are being greatly impacted by the disruptive technology landscape, this year's MissionLink cohort demonstrates that a next generation of solutions are capable of meeting the mission's most complex needs with bold ideas, transformative capabilities, and innovation urgency. linkedin.com/pulse/missionl…
My key takeaway from moderating OODAcon's AI agent panel: The agent hype phase is officially over. We're in the production era, and the real-world friction is clear. The Value is real: Slashing compliance drift from days to mins, empowering 10k+ field techs with agent support, and stopping BEC in less than 3 hours. The Barriers aren't tech: They're people and process. The core gaps are Accountability, Inventory, and Control. The Future is clear: The "moonshots" (like AI defender SOCs) depend on solving governance first. The defining question is now: "What can you prove your agent won't do?" Thanks to @ooda (@bobgourley + @MattDevost ) and all the panelists: Andrew Black (Kovr.ai), Josh Ray (@blackwirelabs), Tom Quinn (@TRowePrice ), and David Ginn (@johnsoncontrols )
Everyone who was in the room was moved by this interlude as we explored the connection between technology and art. A performance that I will always remember.
Awesome to see @Grifter801 at OODAcon this year!
