A translator tells you what a phrase means — not what’s really going on. 🇬🇧 I vibe-coded an app for my family to navigate life in a foreign language, and it turned out useful enough to open for beta: iPhone TestFlight → testflight.apple.com/join/ya… The difference in one shot. Someone drops “Did you hand your boy VA a P45?” in a local chat — Google gives you a literal mess. My app explains it: a P45 is the UK form you get when you’re fired, so the phrase means “did you sack him?”; the tone is an informal, sarcastic jab (think failing football manager); and it even hands you a native analogy — “когда уже дадите ему расчёт?”. That’s the whole point — context, register, nuance, plus 3 ways to phrase your own thought and a camera mode for signs and menus. Built Russian → English first, now also French, Spanish, German, Italian. Early version, so feedback and ideas very welcome 🙌

Claude Code is about to release a feature called /workflows that I think will be extremely significant. Especially for Enterprise AI. I talked about this in 2024 in a post called Companies Are Just Graphs of Algorithms. Basically the idea is that all work is just an algorithm, i.e., a series of steps to accomplish a goal. Skills and Cowork have been heading in this direction already, and we've seen what that's done to company valuations in various spaces. Well this is closer to the final form. It's turning the regular, expected work that's done in companies into pseudo-deterministic workflows that follow defined SOPs. The human role will be determining what problems to solve (taste, expeirence, etc), building new products from that, and then optimizing these workflows from above. But the work itself will be these workflows executed according to SOPs.

Milla Jovovich has a Github 😏 She's co-developed the highest-scoring AI memory system ever benchmarked with @bensig Totally free and OSS. What a boss.
Excited to announce a new open-source, free-to-use memory tool I have been developing with my good friend @MillaJovovich. The project is called MemPalace and it is an agentic memory tool that scored 100% on LongMemEval - the industry standard benchmark for memory… this is higher on than any other published results - free or paid - and it is available now on GitHub. You can check out Milla’s video about it on her Instagram. I’ll also put some links in the comments below - please try it out, critique it, fork it, contribute to it - and join our discord.

Those who write software write the rules by which everyone else lives. Software engineers have become de facto social engineers — without mandate, without accountability, without a code of ethics. In medicine, one cannot practise without a licence. In tech, one may build a system that affects billions without sitting a single examination in ethics.​​​​​​​​​​​​​​​​ #ada

Amidst all the discussion about how AI will transform business, here’s a thought worth considering: money has always been made by exploiting three fundamental human traits — stupidity, laziness, and greed. The real question is whether AI will change any of that. :) #ada

At long last, I’m in a position to deliver quality solutions myself rather than perpetually persuading developers to do the same. #ada #claude #vibecofing

Over 80% of currency trading volume today is driven by algorithms, not humans. And here’s the thing: until recently, all this algorithmic trading ran on top of infrastructure designed for people. Exchange APIs still assumed there was a developer on the other end who would write wrappers, handle request signing, and deal with error handling. Kraken just released something that shows where the industry is heading. Kraken CLI is an open-source Rust utility designed to let AI agents interact with the exchange directly. But the real story isn’t the tool itself. It’s the signal. A major exchange is building an interface not for a trader staring at a monitor, but for a language model working within a context window. The economy of the future is automatic transactions between agents. And infrastructure is starting to wrap itself in interfaces designed not for human eyes, but for machine consumption. blog.kraken.com/news/industr…

Chatted with a Maxon team at @SpaceCommExpo who make servo drives for Mars rovers. Product quality speaks for itself — rovers designed for 90 days have been running for years. But for the company, space isn’t the business. It’s the reputation. “Our drives operate on Mars” — after that, any conversation with a buyer on Earth goes a bit differently. Essentially, Mars became the best quality control department you could imagine.

to be part of the team building CROSSx — the first execution-only crypto ECN. When the biggest names in TradFi and crypto back your infrastructure — you know you’re solving the right problem. This is fuel, not a finish line.
Crossover Markets is proud to announce its $31 million Series B fundraise at a $200 million valuation. Led by Tradeweb with participation from DRW Venture Capital, Illuminate Financial, Ripple, Virtu Financial, Wintermute Ventures, and XTX Markets, this milestone marks the continued convergence of traditional finance and digital assets. The investment will also bring institutional spot crypto liquidity on CROSSx to Tradeweb’s global client base, combining our execution only ECN with one of the world’s leading multi asset electronic marketplaces. As institutions increasingly require speed, transparency, and clear separation of duties in digital markets, we’re pleased to be building the execution layer that meets those standards by bridging the best of traditional market structure with the future of digital asset trading.

Over the weekend, I built a fully functional mobile app for CROSSx. No prior mobile development experience. Onboarding first users this morning. We had a contractor quote on the table — tens of thousands of dollars for the same module. I turned it down today. The only real bottleneck left is Apple's review process — which says everything about where friction lives now. Not in building. In bureaucracy. This isn't a productivity story. It's a signal about what "technical co-founder" means in 2026. The moat is no longer in writing code — it's in knowing what to build and why. Claude Code handled the implementation layer. I handled the judgment layer. But the contractor quote isn't just a cost comparison — it's a proxy for time. Weeks of spec documents, alignment calls, revision cycles, handoffs, and the inevitable "we need to revisit the requirements" conversation. That entire loop: gone. The real unlock of this technology isn't cost reduction. It's compression of the iteration cycle — from weeks to hours. That's not a linear improvement. That's a phase transition. The world didn't gradually change. It snapped.

In a recent interview with Joe Palmisano, CMT of Connect Money, Crossover Market's Co-Founder and CEO Brandon Mulvihill shared his thoughts on the structural evolution of crypto markets amid growing institutional demand. Brandon explores the most pressing topics in crypto trading today, from bank-led custody and US regulatory clarity to the conflicts within vertically integrated exchange models and why separating custody, clearing, and execution is key to the industry's maturity. He also highlights the importance of low-latency execution in crypto, and how CROSSx's faster infrastructure enables market makers to process more price updates, manage risk, and reflect real-time market movements.
