@royvanrijn Of course you are, Roy. Nice!

Analysing and proving a lot of the structure behind the Jacobian conjecture's counterexample, really interesting! github.com/royvanrijn/jac…

@Mangan150 Inspired by some of your earlier posts about this I've been experimenting with resistance training superimposed in a Norwegian 4x4 format. This morning it was a sandbag workout, walking during recovery intervals. Thanks as always, P.D.

How to increase VO2max with high intensity resistance training Many studies have found only a small increase in VO2max with resistance training. Understandable, when you see how many people train. Not going to failure and using relatively long rest intervals (minutes) between sets. Large, compound exercises, e.g. leg press, chest press, involve large amounts of muscle mass and increase heart rate. Then, minimal rest between sets, that is, no deliberate rest, only the time it takes to move to another exercise station and start, keep heart rate elevated. My own heart rate stays in the 140 BPM range during my workouts. At my age, my max HR appears to be around 165 (calculated value: 211 - .64 x age, the NTNU/HUNT formula, best for those over age 60). I also add a metabolic finisher at the end of the workout, such that my heart rate gets close to max. Basically one high intensity interval. Examples: rowing machine, air bike, machine deadlifts. Takes one minute or less. Exercises that involve free weights while standing, e.g. squats, overhead press, as well as bodyweight exercises like chin-ups or dips, elevate heart rate even more than most machine exercises. A set of chin-ups to failure leaves me breathless. Deadlifts, same. If you only perform one set to failure, and alternate muscle groups, there's no need for deliberate rest between exercises. How often a workout like this should be done is individual. It generally requires plenty of recovery time. I've found that for me the best frequency that allows me to recover well is once every four days. I'm active on off-training days, e.g. walking or swimming, but whether that contributes to VO2max seems doubtful. All of this is how high-intensity resistance training also becomes cardiorespiratory conditioning and can increase VO2max (cardiorespiratory fitness).

Age: 71. Resting heart rate: 40 HR, one hour post high-intensity workout: 60 Calculated VO2max, ~54. I'll take it.

@royvanrijn ... you just might be a geek.

When your partner sends a photo of her new earrings, and instead of just giving a compliment like a normal person... you count the crossings, over/under data, signs and order, derive the Gauss code, install Sage, and discover she’s wearing K11a73 katlas.org/wiki/K11a73

@stylewarning Enjoy Lisp# 😉

Personal news: I joined Microsoft to help lead the implementation of quantum fault tolerance, which I'm having a blast with already. After almost 2 years of doing defense technology work, I'm really glad to be back in quantum computing.

Great idea. Bought the Annual Pro plan and haven't been able to download explainer videos for the last couple of hours. Please fix!

@skirano Dude, that's pure magic.

You can now run MagicPath as a native canvas inside Codex to design and build functional apps. It's pretty incredible. Here's how to do it 👇

As a 71 y/o myself, thanks for continuing to inspire folks to effectively but efficiently increase fitness. When I am tempted to overcomplicate my weekly routine, I apply Mangan's Razor, which Grok says would be something like: "Do not multiply workouts, dietary rules, or supplements beyond necessity."

Yesterday, someone posted that being in peak shape in your 70s is pointless. I turned 71 last month. Here is the reality: Getting lean, fit, and strong isn't a vanity project. It's survival. Here is why you need to start now:

if you’re freaking out about Mythos, remember: Never make any major life decisions within 30 days of a meditation retreat, psychedelic trip, or first encounter with a frontier AI model.

Now that Artemis II has launched we have 10 days to get everyone on Earth a Planet of the Apes costume so we can do something hilarious when the astronauts return 😁

I'm looking for work, so if you want an experienced devrel person/leader, if you need a technical educator, or if you want some consulting on how to help your devs work more effectively, ping me.

I'll take Decisions That Defy All Logic for $2000, Alex. Sharat is the single best technical community leader I've ever worked with or worked for. Full stop.

@RickRossTN @_LuoFuli Was reading this update with sleepy eyes and then noticed Rick Ross in my timeline and that you're a fan, so we'll give it a closer look. Hope you've been well, Rick.

@_LuoFuli MiMo-V2-Omni is good enough to release now - we want it and we need it. Just continue to refiine, and release an iterative update not too long after!

MiMo-V2-Pro & Omni & TTS is out. Our first full-stack model family built truly for the Agent era. I call this a quiet ambush — not because we planned it, but because the shift from Chat to Agent paradigm happened so fast, even we barely believed it. Somewhere in between was a process that was thrilling, painful, and fascinating all at once. The 1T base model started training months ago. The original goal was long-context reasoning efficiency. Hybrid Attention carries real innovation, without overreaching — and it turns out to be exactly the right foundation for the Agent era. 1M context window. MTP inference for ultra-low latency and cost. These architectural decisions weren't trendy. They were a structural advantage we built before we needed it. What changed everything was experiencing a complex agentic scaffold — what I'd call orchestrated Context — for the first time. I was shocked on day one. I tried to convince the team to use it. That didn't work. So I gave a hard mandate: anyone on MiMo Team with fewer than 100 conversations tomorrow can quit. It worked. Once the team's imagination was ignited by what agentic systems could do, that imagination converted directly into research velocity. People ask why we move so fast. I saw it firsthand building DeepSeek R1. My honest summary: — Backbone and Infra research has long cycles. You need strategic conviction a year before it pays off. — Posttrain agility is a different muscle: product intuition driving evaluation, iteration cycles compressed, paradigm shifts caught early. — And the constant: curiosity, sharp technical instinct, decisive execution, full commitment — and something that's easy to underestimate: a genuine love for the world you're building for. We will open-source — when the models are stable enough to deserve it. From Beijing, very late, not quite awake.

@PCollinsTribute We saw this concert Saturday evening, and I’m still thinking about how great the band gelled and about the caliber of talent that was on the stage. I’ve been experiencing Phil Collins earworms since.

A CONCERT I WILL NEVER FORGET Real fans. Real reactions. Real goosebumps. If you’ve ever wondered what it’s like to be in the crowd at The Phil Collins Experience, take it straight from some of our fans! Find a date near you: thephilcollinsexperience.com/tour-dates #PhilCollins #Genesis

Join me next week to talk about what’s going on in the AI space and help you get started building agentic systems!

@maria__violaris I like to walk-on to music that put me in a good state of mind to present, whether it's relevant to the talk or not. Current favorites for that are "Can't find my way home", and "Voodoo Child", although occasionally "Comfortably Numb" :-)

I've now been asked twice if I have any preferred intro music when going on-stage for a quantum talk but I can't think of anything... any suggestions?! Ideally a well-known pop song with lyrics that can be re-interpreted as having a link with some aspect of quantum!

@ismaelfaro @karpathy @matiasmolinas Dude!

@karpathy WIP with @matiasmolinas 🫣

Bought a new Mac mini to properly tinker with claws over the weekend. The apple store person told me they are selling like hotcakes and everyone is confused :) I'm definitely a bit sus'd to run OpenClaw specifically - giving my private data/keys to 400K lines of vibe coded monster that is being actively attacked at scale is not very appealing at all. Already seeing reports of exposed instances, RCE vulnerabilities, supply chain poisoning, malicious or compromised skills in the registry, it feels like a complete wild west and a security nightmare. But I do love the concept and I think that just like LLM agents were a new layer on top of LLMs, Claws are now a new layer on top of LLM agents, taking the orchestration, scheduling, context, tool calls and a kind of persistence to a next level. Looking around, and given that the high level idea is clear, there are a lot of smaller Claws starting to pop out. For example, on a quick skim NanoClaw looks really interesting in that the core engine is ~4000 lines of code (fits into both my head and that of AI agents, so it feels manageable, auditable, flexible, etc.) and runs everything in containers by default. I also love their approach to configurability - it's not done via config files it's done via skills! For example, /add-telegram instructs your AI agent how to modify the actual code to integrate Telegram. I haven't come across this yet and it slightly blew my mind earlier today as a new, AI-enabled approach to preventing config mess and if-then-else monsters. Basically - the implied new meta is to write the most maximally forkable repo and then have skills that fork it into any desired more exotic configuration. Very cool. Anyway there are many others - e.g. nanobot, zeroclaw, ironclaw, picoclaw (lol @ prefixes). There are also cloud-hosted alternatives but tbh I don't love these because it feels much harder to tinker with. In particular, local setup allows easy connection to home automation gadgets on the local network. And I don't know, there is something aesthetically pleasing about there being a physical device 'possessed' by a little ghost of a personal digital house elf. Not 100% sure what my setup ends up looking like just yet but Claws are an awesome, exciting new layer of the AI stack.

@brunoborges We just can’t have nice things
