Dear all companies sending me surveys: my willingness to recommend your product (nearly 0) is disconnected from how much I like your product. (ranges from 0 to 10) Please do not convolve them.

I have a similar problem with “up and to the right”. “Up” I get but time moves inexorably to the right. There is no other option than “to the right” - the only variable in that equation is “up”! Why add an invariant as a qualifier?

Why do people say, “if and when”? If “when” is added as a required option then there can be no “if”. Makes no sense.

@Cdempsey44 Fun read! I was right there with you about half the way!

@Falconortizx IMHO this is the major unsung win Apple has - unified memory and token generation performance per watt. Nobody seems to be talking about this but it’s a huge advantage.

@anders94 I think that’s one of the best approach we can have right now . Having in mind there’s so much competition for comercial ones everyday. Qwen has become one of the best options right now

Just learned that in Xcode’s Apple Intelligence you can add a local LLM using ollama and have private AI coding assistance without an internet connection.

@Falconortizx For me the quality lags commercial models only by a matter of months. At this point I use local models (gemma4 / qwen3-coder) to write tests and non-essential UI / backends. I’ll use a commercial model for architectural planning but implement things myself using local models.

Apple Intelligence + Ollama for local AI coding in Xcode is the combo most devs are missing 🍎 I've been running local models on my Mac for months. The privacy advantage alone is worth it — no code leaving your machine, no API costs, no rate limits. But real question: has anyone actually benchmarked this vs sending to Claude/Copilot for real-world coding tasks? I'm curious if the quality gap is still noticeable or if local models have caught up enough for daily work.

The Chernobyl accident happened 40 years ago today. It is a fascinating case of large system breakdown that hastened the end of the Soviet Union. The Chernobyl series HBO did on it is required watching. amazon.com/Chernobyl-Seas…

Models inspecting compiled code for bugs without source removes the last security moat closed source had.

@austincampbell So in DeFi you would use tokens that represent “settled” tokens. They would essentially be locked in place until the representative tokens are returned.

@austincampbell “As currently constructed” I agree with you. I never really understood the irreversible argument though. Reversibility is something you can add in a smart contract.

Some gross misrepresentations of my views in here. On purpose for drama, or on accident because nuance is lost? Either way, let's be as clear as possible: 1 - Securities have to have a record where ownership is known. 2 - They also need to have controls so that they can be frozen, clawed back, re-allocated, etc. to comply with current securities law without creating massive liability that makes putting them onchain non-viable either from an economic perspective (the concern at the root of SAB-121, malformed and broken as it was) or a legal one. 3 - Under current risk frameworks post D-F, you also cannot have a single point of failure for these things across systems, a point the OCC is more up to speed on than the current SEC, though the SEC is rapidly climbing the curve. What does this mean? I agree you can definitely record securities onchain on a public permissonless network! That part is not surprising to anyone. People do that right now. There are multiple licensed transfer agents (e.g. @Securitize, @SuperstateInc, etc.) all doing this right now. That's not the hard part from the public permissionless chain perspective. The question is doing anything with them after that. Right now, the answer is mostly, you can't. One way sends? Easy. Putting securities inside an AMM pool or borrow lend protocol? Net settlement and margining architecture? This is what I have been repeatedly saying does not work (and, in fact, the USD stablecoins inside these things in current DeFi are a ticking time bomb). Why? If you have a fully permissionless, undifferentiated pool, or you have 24/7 real-time trading of these assets, this means it's a matter of time until one of the following things happens: 1 - You have an OFAC issue, hack, or fraud problem causing you to have to freeze entire asset pools, including commingled funds (see: Tornado Cash). 2 - You have a fast enough hack that you don't react before the funds are gone, meaning that whichever regulated entity was the custodian or caretaker is now liable to users for the whole thing (catastrophic if large enough, and why SAB-121 required 100% capital for all exposures). 3 - You have funds transmitted in error that need to be reversed moving through some of these complex implementations. 4 - You have an issuer themselves get hacked, such that all the powers they have to control these things are now in the hands of the bad guys. You cannot rely solely on an issuer of a token to fix those problems. If you let securities or rwa tokens into the current version of DeFi, it's going to eventually be a death sentence for both the protocols tokens are in and the issuer (who will hold the bag on liability). The regulators seem to agree with me on this: look at what the SEC and OCC are not, in fact, allowing their registered entities to do. There's no easy fix here if you want to remain truly permissionless. Either you are going to need third parties deputized to have vast powers over a chain to halt these kinds of issues and remediate them, or you should probably not be combining RWA with smart contracts / complex implementations. At a bare minimum, DeFi needs a complete ground up redesign just to comply with basic things like being able to uniquely segregate funds if they don't want entire protocols nuked by a freeze order. Note that this doesn't mean you have to violate the immutable ledger properties: you can reverse transactions by force sending them back in a subsequent transaction, you can reverse hacks with targeted transactions to send flows back the other way, and so on. The ledger is immutable, but that doesn't mean you can't later send things back. However, the current chains take decentralization to the extreme, so when a thing like Drift happens, nobody acts. That won't be the case for long, with the new rules being implemented for Genius. People are going to have to start acting in ways that blow up the current system, or worse, breaks are going to happen so severe the entire edifice collapses. Disagree? Here's a thought experiment: what if North Korea gets ahold of Tether or Circle's smart contract keys? What happens to DeFi on Eth?

A friend of mine, Bob Schulein, helped build the laser communication system that Artemis II is using to send this 4K live video stream of their destination, the moon! The link is going through Australia right now. youtube.com/watch?v=6RwfNB…

My take on Bitcoin and quantum computing: nehanarula.org/2026/04/03/bit… tl;dr: I think the risk is high enough to warrant prioritizing designing, implementing, and evaluating post-quantum signature schemes and consensus upgrades in Bitcoin now.

@JSeyff @EricBalchunas @TukiFromKL It used to do that when private links were the norm but it fundamentally relies upon encrypted channels for updates now.

@EricBalchunas @TukiFromKL The entire banking system you’re describing does not use cryptography for the basis of its existence though

🚨 Do you understand what Google just published.. they said a quantum computer could crack Bitcoin's private keys in 9 minutes.. everyone's panicking about crypto.. but nobody's asking the real question.. if quantum cracks Bitcoin.. it also cracks your bank account.. your credit cards.. SWIFT transfers.. stock exchanges.. military communications.. nuclear launch codes.. every single HTTPS website you've ever logged into.. the same encryption protecting your savings account at Chase is the same encryption protecting Bitcoin.. if one falls.. they all fall.. and here's what nobody's telling you.. this needs 317,000 qubits to work.. the best quantum computer on earth right now has about 1,000.. they announced a countdown.. and the clock just started.

@zooko Howdy

hey errybody please reply to this so i can see who u r kthxbye

If the next Mac Studio comes with M5 Ultra and 1TB of RAM, it’s over for the local LLM world. Apple wins.

@KyleSamani network.radiustech.xyz We’ve been doing exactly this.

Supposedly 100M x402 transactions for $30M in payments volume Where can I try this myself?

@govfuturist @RkBench @circle @noahspaulding I was unable to find one but I’m sure it’s there somewhere

@RkBench @anders94 @circle @noahspaulding Is there a neon bitcoin sign in the window?

Proud of the old team. From Congress St to the top of the world. @anders94 @circle (not pictured @noahspaulding ).
