Thanks for the emergency update Chris! I'm going to share an unpopular opinion in that there were 2 issues with this exploit. The 1st and most infuriating issue is with the Coinkite entropy code. That's unexcusable and horrible. The 2nd issue is HODLers choosing a niche, "security 1st" hardware wallet and not rolling their own entropy and not using a strong passphrase. They would've been better off with a mainstream, user-friendly hardware wallet like a Ledger or Trezor.

40k Excited for the conversation that took place on sessions recently; Simon Dixon vs. Jeff Booth. Excellent signal, I am always confused why Simon does not get more exposure. I would like to see him on Citadel & TFTC. It was a welcome white pill, a masterclass from Jeff. We are winning.
Marty, can u get Doomberg on TFTC?

I’m randomnly working through the back catalogue to learn things as they come up in my setup.
Just learnt the difference between Snap and Flatpaks in eps 532, 501 and 499. It’s evergreen content, thanks for the work you put into creating these and the passion in the delivery.

20k have a great time at Linux Fest.
Do you have any suggestions or old episodes to help new Linux users decide on distros as a daily driver?
I’m not a total Linux newbie, have been running a couple of Ubuntu servers and Linux Mint on a laptop for over a year now, but want to set up a Linux desktop as a daily driver now.
I’m looking at Pop OS for now, any suggestions appreciated.
Thanks from New Zealand!

10k Belated boost for this, and other episodes.
So much of what Dash talked about resonated with me. Running multiple nodes, disappointment in Bitcoiners and looking for answers somewhere else.
Thanks for the thought provoking conversations Cody.

10k It's not about breaking the wallets. It's about litigious grifting. By making a claim on "dormant" bitcoin in the New York, the claimant, a Wyoming LLC, sets up two scenarios:
1. If Quantum "breaks" a wallet previously awarded, the Wyoming LLC will use their legal title to sue for possession/compensation (or be paid to go away).
2. Ahead of Quantum being a real threat, the Wyoming LLC can sell itself with the legal title to the bitcoin addresses as part of its book value.

10k Boost for the road!
I’d like to hear your opinion on Open Source LLMs. If an LLM is Open Source, how much can we know about the security and telemetry of that model? If the source code is visible and we can audit it, can we be reassured of what’s being logged or used for training, or is it still a black box?
I’m having a debate with a friend at the moment, he says that LLMs are black boxes, even if they are Open Source.
What say you?

5k Make sure to mention repeatedly, for the benefit of the Southern District of New York Attorney General, that your joke about availability of code RHR for a discount on Strait-of-Hormuz Bitcoin shipping insurance premiums payable to Iran was a parody or completely a joke and not to be taken seriously.

5.4k Time traveller boost, I’m going back over episodes about File systems. Who knew that you could customize the file system in your OS. Wow!
Could you explain the difference between corporate disros (like Ubuntu & PopOS) and community distros. Pros and cons, trade offs, that kind of thing.
Thanks.

4.6k How does Nebula compare to Tailscale for the purpose of isolating a server running OpenClaw (or Hermes) in a network?
Ive built a plan to isolate a small server inside my LAN so that I can experiment with agents, one item on the plan was creating a Tailnet with only the devices I want the agent to connect to.
Can I do that with Nebula? How would that differ from using Tailscale?
Thanks!

4.6k I enjoy the AI subject matter and the way you cover it.
I’m fairly new to the Linux and FOSS world and now I have to weave AI into it all, so I appreciate the way you bring it into the Linux ecosystem, give examples of practical use cases and also potential hooks to be aware of.
AI is here to stay and everyone needs to understand how to use it, so leep the content coming, that’s my vote.

4.6k Great interview Cody, this really got me thinking. It seems like many of us are no longer questioning narratives or thinking adversarially and we’re weaker for it.
I no longer think Bitcoin is a done deal and all we have to do is sit on our stacks and post toxic memes to anyone who disagrees with us.
I think there’s a lot of work to do and we’re a lot further from our goals than most Bitcoiners realize.
Really enjoyed Roger’s takes and your questions. Thanks.

4.6k Loved this episode. Hearing Mehdi’s personal story over decades and his insights into how things were in Iran before the revolution was fascinating. Listening to a conversation like this is a much better way to understand what’s happening there now than all the headlines and clickbait on MSM.
Bravo Cody and Medhi. Thank you.

Thanks for the update on this Chris. Keep ‘em coming, people are afraid and a bit freaked out so some calm words and solid advice from an OG like you will be really helpful. Interesting spin on random numbers on LUP too, seems like this is not the first time generating random numbers has led to problems.

Thank you for taking the time to warn us all about the exploit. Yet again you are keeping my finger on the pulse of the events & news that really matter. Thank you & bless you for this service. May your roads be clear and scenic! BTW the boost value is not a code, just the max palindromic value I could send you.
