suddenly a project written in Bend with 500 stars, I had no idea?
(this actually makes me anxious because there is so much I want to improve NOW, but I'm stuck doing business 😭)
really cool though, anything done in Bend should automatically get exponentially better soon 🫡

Can we PLEASE normalize just hanging out at each other’s houses again? Why does every friendship meetup need to be a whole production, a restaurant reservation, and a $150 bill? I just want to sit on your couch, drink something, and talk for hours.

interpretability might be the most important scientific problem in the world right now, as I don't think we can solve alignment if we don't know what we're building. I think I have good news about it. I co-authored early work in mechanistic interpretability at OpenAI and came away pessimistic, because neural networks appeared to fold into arbitrary tangled knots. years later, I started openai's first large-scale automated interpretability project, finding about 2% of neurons legible with the primitive tools we had
with modern agentic tools and a much closer look, the picture looks totally different. the vast majority in models up to trillions of parameters are legible, and their circuits beautiful. many famous examples of tangled neurons turned out to be misunderstood. The roadblocks I expected mostly aren't there. I now think ambitious interpretability will be solved by the time we need it most, and possibly quite soon, as automated scientists keep improving. it may be a bitter lesson for interpretability: the simple thing, at absurd scale, works

webassembly was supposed to replace docker
except... the great part of docker is that it *just worked*
if i can do it on my laptop, i can do it in a container
but webassembly went a different direction
instead of focusing on linux compatibility, they went off and built the component model that has very very little adoption
which is exactly why we built agentOS to bring linux compatibility to webassembly:
- posix filesystem
- networking stack
- process trees

we’ve been heads down on the new @tenordesign and it’s something we’re very proud of and i know you’ll enjoy using.
the way we design today has fundamentally changed, the tools have changed, the process has changed but it’s certainly for the better in my opinion. we think you’re going to love what we’ve created with Tenor.
using Tenor as a space to explore design as code and working with agents to refine and get what you’re looking for just right is exactly the type of tool Tenor is.
we all have our ways of creating, designing and building and Tenor simply helps give you that space to take what’s in your head into a real interactive thing that you can then share with other agents to place within projects you already have.
we’ll be sharing more soon. Tenor is now available for everyone so… Try Tenor.
tenor.design
Meet Note, Tenor’s voice-enabled agent.
Talk through an idea, see it take shape, and keep refining it together without losing coherence.
You set the direction.
The conversation moves the work forward.

pi durable is so so good @badlogicgames
built an agent on top of @VictorTaelin ‘s OptChat memory idea (genius!) that runs in a durable object and can hack on/redeploy itself (resuming durably without issues!)
hooked it up with codemode +@RhysSullivan ‘s executor and it’s absolutely ripping
don’t know why i’d bother using instinct/muse/etc. after this

Effect TS is the modern reincarnation of Haskell, and I’m all in for it.
You’ll never go back to your old ways once you see the beauty of functional programming and IO Monads.
‘Tackling the awkward squad’ is a great read if you want a richer understanding of effects in general cs.tufts.edu/comp/150PLD/Pap…

Building my own personal health database. Whole genome sequencing, lab test results, Whoop data (captured with NOOP github.com/ryanbr/noop, no subscription, data stays local), and custom code written for continuous monitoring and advisory.
I think medicine will see a fundamental shift. So far throughout history, medical research has been for finding the "average solution" that would most plausibly work for all people. AI will change it by making medicine personal. Smart people will have started accumulating personalized data now, even when healthy. These data will come in handy when we age and start to experience chronical illnesses 10 or 20 years from now.

I would argue that TLA+ is still useful even if we throw away the temporal operators altogether. People are trying to extract high-level protocols and find flaws in them. LLMs help them. Is this better than reading pages of text? I think so.

At the top of my AGENTS.md:
- NEVER write unit tests after you write code.
- Highly prefer E2E tests as the sole testing mechanism. Use them to verify complex features work. At the end of E2E tests, produce a verifiable and repeatable artifact.
- If you must test a system in isolation, FIRST write all the ways it could fail, THEN write the code.

Rivet Actors & Workflows live forever through hibernation
But OpenTelemetry traces need to have a bounded lifespan
So how do you build a trace for something that never ends?
A crash course on rays and links:
~~~
A ray makes it possible to correlate multiple traces together
When an event enters the system (HTTP request, schedule), it crates a new ray ID
Every subsequent hop through your system is associated with the same ray ID.
Examples of places where two traces are correlated by a ray:
- Actor-actor requests
- Creating new actors & workflows
- Scheduling actions
~~~
More importantly, rays can correlate traces that are days, months, or years apart. For example:
1. User signs up for an account
2. User actor starts a workflow that sleeps for 14 days
3. That workflow sends the user an email that trial ends
These events are all correlated with the same ray to make it easy to trace back to the original request
~~~
However, traces correlated by rays can get tricky to read when a single ray causes multiple things to happen in parallel
For example:
- A user signs up
- In parallel (each as their own trace):
- Creates Stripe customer
- Registers with Resend
- Sends event to PostHog
Those 3 traces in parallel can be hard to tell what causes what
~~~
This is where links come in
Links tell you which trace caused another trace, making it really easy to create a graph of where a trace originated
In the above example, if we want to find the signup request that caused a Stripe customer to be created, we can look up the link ID to find the original request
~~~
We wanted to wait to ship OpenTelemetry until this mechanism was solid acrosss the Rivet ecosystem
Appreciate all of you that have waiting a long time for this!

I have a dark, kinda tragic personal announcement.
I've decided I'd rather take $0 than accept a settlement that requires me to stay silent about what happened to me. I have since fired my lawyers at @sanfordheisler & will be releasing all the evidence from my time @hack_vc on Wed 8/26.
INTRO: I've been in crypto for 9 years. Most recently I was a partner & head of platform @hack_vc which is a $600-700M crypto VC firm. Many of you may know me from my time as Head of Growth at @StellarOrg in 2017 (worked w/ the Mt. Gox founder), @Solana in 2018 (joined under ~10 ppl, but quit before my cliff), & @Fhenix in 2024. Or have attended one of my @DystopiaLabs ETH events (2019-now).
Last year, I was forced to work through a serious medical emergency while at @Hack_VC due to threats by @alpackaP @dbulaevsky, saying that they would blacklist me from the space if I quit before finishing the hacksummit conference & side events that I was helping with during @kbwofficial. I was working 13-14hr days, 6 days a week, sleeping 0-4 hrs a night, and had documented Graves' disease, hyperthyroidism, and severe insomnia. I repeatedly asked to quit. Hack VC refused. This + other threats and intimidation went on for almost a month.
The conditions got so bad I attempted suicide.
The fucked up part is that, even after the suicide attempt, I told everyone at Hack VC (in writing) that I had no plans to sue. I was scared & extremely sick. I just wanted to leave. I told them that as long as there was no retaliation or badmouthing - I had no plans to sue.
@Hack_VC chose to retaliate.
After just 1 month after my near suicide, Hack VC mishandled my COBRA health insurance, refused to fix things, kept shooing me to customer support (when it's legally Hack VC's responsibility to fix this), and my insurance had issues and was not fixed for almost 4 MONTHS. Hack VC did not fix everything until I hired lawyers and had them force Hack VC to adhere to the law & fix my COBRA insurance issues. The sheer cruelty of an employer harming someone's health insurance almost immediately after they nearly committed suicide is extremely fucked up.
And, even during the legal engagement, Hack VC continued to lie & attempt to harm me through their lawyers and other employees/partners (multi-million dollar carry & clawbacks can make even the nicest ppl willing to turn the other way or lie). @0xRodney @IsTheBaron @roshunpatel @Alex__Botte.
Now. Almost an entire year of engagement & my near suicide anniversary coming up, our lawyers (mine & Hack VC's) have reached the point of preparing for private mediation and settlement. And...I realized that I just can't do it. I don't want money in exchange for silence. I'd rather speak.
I fired my lawyers yesterday.
In case it needs to be said, I did a good job at Hack VC. I was only there full time for 7 months; been part-time since 2021. I got a $50k raise to $300k, $30k bonus, and promises of additional carry that would have been implemented about a week or so after my last day. I was also offered admission into the GP entity (but not sure if admission was actually completed bc it was during my medical emergency). This + my resume, should show that me suing is not a money grab; I was genuinely harmed.
I'm aware that I'm just one person (who is not rich) facing a $600-700M VC institution. I've been told by @alpackaP that he's known most of the managing partners at most VC firms for almost a decade and he could absolutely blacklist me.
I'm also painful aware that the conclusion of this will probably be extremely poor for me or death - but I've accepted it.
Sharing with other web2 & web3 VCs:
@paulg @ycombinator @500STARTUPS @a16zcrypto @PanteraCapital @dragonflyvc @RaceCapital @hosseeb @haunventures @hiFramework @ElectricCapital @blockchaincap @Delphi_Digital @variantfund @1kxnetwork @archetypevc @shimacapital @robotventures, etc.
TLDR; I’m done with continued threats, pressure, and intimidation. I'm not going to take a payout and allow Alex or Hack VC to walk away from harming me. As mentioned, I'll be dropping the evidence from my case on Wed 8/26 (or before) -- privacy be damned.

Some personal news:
I'm thrilled to announce that I've joined @hack_vc as a partner & head of platform. 8 yrs in crypto = a lifetime.
It all started in 2017 when a random recruiter slid into my DMs and told me about a job at @StellarOrg. I took a call with @JedMcCaleb (founder of Mt.Gox, Ripple, and Stellar) & Brit (co-founder of Lightyear).
That was where I learned about (and fell in love with) crypto. I decided right then and there that I was going to enter the space whether they hired me or not. So 😂-- I offered Stellar a 1 month contract and told them they could pay me whatever they wanted, but that I was going to perform so well that they'd want to hire me at the end of the contract.
Obviously, they accepted.
1 month later, they promoted me to head of growth & my crypto journey began.
After I left Stellar, @edithyeung & @chrismccann introed me to @rajgokal @toly from @solana. I met them very, very early when Solana was still at the whitepaper stage and had just gotten accepted into @500GlobalVC. I was with them as their head of growth till right before they launched their testnet.
Then, after that, I did a short stint at Tezos (😅), burned out, and decided to found my own startup @DystopiaLabs which was focused around building dev ecosystems + running events. I made a lot of good frens & threw a total of 17 ETH conferences around the world.
Special thanks to @clairekart @Cameron_Dennis_ @ekang426 @Minittowinit @levychain @Sim_Pop @YalorMewn @VanessaGrellet_ @cryptomastery_ @StaniKulechov @LukeYoungblood @beechainstack @pet3rpan_ @marek_ @sui414 and so, so many more for supporting or speaking at our events over the yrs 🙏♥️
Most recently, I was @fhenix which is an FHE infrastructure project created by @guyitz @GuyZys. I joined when the whitepaper was released & was with them till their second testnet. TLDR I'm very bullish on the future of the FHE category & knowing the team -- think they're very well positioned to succeed 🚀.
As for what’s next...
I'll be diving head first into venture capital 👀.
If you're a founder or a dev working on cool shit, I'll be in SF for @ethereumsf & the Stanford AI Summit. Slide into my DMs if you'd like to catch up (or want some marketing feedback) ✨

I had a major shift in my worldview recently. The first topic I want to unpack: transparency vs. privacy.
I’ve been in crypto 8 years, helped 2 privacy projects (@EspressoSys when it was a ZK L1, @fhenix back when it was an FHE L2 on ETH) and put on a number of privacy & encryption focused events. I supported privacy, but TBH, I only understood it in a “cute,” abstract, and intellectual way.
I grew up middle class in the US (yes I'm a citizen). I’ve always operated under the assumption that most people in the world (US + abroad) are good / kind and just want to do right by their loved ones. As long as you don’t give anyone an incentive to harm you, most people will leave you alone (or even help you if they like your vibe). I’ve been to 22+ countries solo, hung out with everyone from fish farmers to billionaires to government officials — never once had a bad interaction with anyone. I was never harmed. Never saw or was exposed to any bad behavior.
I naively thought the horror stories we hear about in the news were outliers & rare exceptions. No system is perfect. Bad actors do exist. And bad things do happen to good ppl. But even then, I still operated under the belief that most ppl in the world were good/ kind. I thought in bad situations, someone would step up and do the right thing when it really mattered.
I was wrong.
What I didn’t realize:
- Transparent systems can be weaponized.
- Bad actors can hijack even government compliance tools to monitor, threaten, and force obedience.
- When every conversation and transaction is tracked, how do you fund defense or even ask for help?
- When people in power are willing to risk everything to win, where do you go?
I always thought: I’ve never broken the law, I have nothing to hide. Now I realize privacy isn’t just for people with “something to hide” — it’s for the vulnerable. It’s the only way for ppl who are in need to get help without being punished for it.
And here’s the other hard truth: most people are “good,” but strong enough incentives will make them look the other way & even support bad actors. Very few will walk away from money or put themselves at risk for what’s right. That’s why bad actors win. Me? I have an abundance mindset. There are infinite ways to make money. Infinite ways to lead a good life. I’ll never compromise my values — why waste years of my life and reputation chasing something misaligned? There are opportunities everywhere.
Takeaway:
- Privacy matters because the world has far more vulnerable people — and far more abuses of power — than I ever realized.
- Transparency still matters too. It keeps a spotlight on bad actors.
- Compliance tools? Necessary at times, but too easily abused. No perfect solution, but the tension between privacy and transparency deserves way more attention.
Shout-out to @charleslu1 @benafisch @benediktbuenz @jillgun @m_mosier_ @guyitz @GuyZys @clairekart @Zac_Aztec @zooko @jswihart @PrivacyEthereum @web3privacy @privacyguardia @VitalikButerin @ameensol @RAILGUN_Project for advancing encryption and driving the privacy space forward. I'm sure there are a gazillion other ppl to thank as well, but starting here. I don't know all of you personally, but just wanted to say thanks.
I didn't understand privacy before, but I'm starting to.
