Perhaps the most addicting quality about AI coding is that it starts to feel like spinning plates at different speeds, and since you’re already waiting, you might as well toss one more into the air. So much so, it never seems to end until it's 2 AM.
We seem close to: - Give an agent access to a competitor app on a computer - Tell agent: Rebuild this app by using all its features - Agent tries app -> documents all flows/features/edge cases - The other agent builds all flows/features - They iterate trying/testing until done
Engineering is now this: new agent -> shift+tab -> wispr plan -> wait -> look at X -> review plan -> make adjustments -> approve/build -> verify it works -> integrate tests -> merge -> go to app

RT Garry Tan Boil the Oceans You know the phrase: “don’t boil the ocean.” Everyone’s said it in some overly ambitious meeting. It’s good advice in normal times. It keeps teams focused. It prevents scope creep. But we are no longer in normal times, and I think it’s time to retire saying it. Artificial Superintelligence means it’s time to boil the ocean. We’ll start with a few lakes first. I was recently with a university endowment’s head of private investing who told me their engineers were terrified for their jobs after seeing what Claude Code could do. And I get it — that’s the natural first reaction. But it’s the wrong one. It’s a zero-sum reaction to a positive-sum moment. Instead of worrying about doing the same thing we’ve been doing for cheaper, why not focus on doing the thing we never even dreamed of doing? Why can’t that endowment achieve 50% net IRR instead of 10%? Why can’t a startup deliver a service that is 100x better than the incumbent? Why can’t we have fusion energy? Why can’t we talk to every single user and have a perfect understanding of every bug in our product? These aren’t rhetorical questions anymore. They’re engineering problems with paths to solutions. Here is what I think is actually going on with the fear: our fear of the future is directly proportional to how small our ambitions are. If your plan is to keep doing exactly what you’re doing, then yes, a machine that can do it faster and cheaper is terrifying. But if your plan is to do something dramatically bigger, then the machine is the best news you’ve ever gotten. If you’re a worker — someone who trades labor for a living — this is the moment to become a builder. Start a business. And if you’re already management or capital, it’s time to go 10x more hardcore on what your aspirations could be. Not eking out 5% efficiency gains. Not increasing profit margins 2% by lowering cost and firing people. Those are the old games. The new question is: what would it look like to build a prod...

RT Sebastian Raschka If you are looking for reading material for the upcoming weekend, (the long-promised) Chapter 5 on LLM self-refinement is now finally out in the early access. Here, we continue the inference-time scaling theme, but we move beyond self-consistency and voting. More specifically, we implement a self-refinement loop, where a model iteratively critiques and improves its own answers. Along the way, the chapter implements several core pieces that will become essential in the upcoming reinforcement learning chapters like log-probability scoring (I finished the RL chapter last week, and it will hopefully be out soon, too). Like always, all of this is implemented from scratch, step by step, of course. I think that seeing it all in working code really helps with understanding how LLM reasoning methods work (versus just looking at the equations). Anyways, with Chapter 5 out, the early-access version of the book has grown quite a bit (~300 pages) and now finally wraps up inference-time reasoning before we transition into the (even more) fun part: reinforcement learning (from scratch!) in the next chapter. 🔗 Here's the link to the book's early access: https://mng.bz/dWGv Happy reading (PS: Sorry for the delay. It turns out the submitted manuscript got a bit backlogged in the publisher’s processing pipeline.

PSA: It seems like the published algo for X doesn't include any of the weights for the final score so there's no way to really know what actually matters. I get that they'd do this to avoid gaming or because they're constantly subtly tweaking them. Anyway, I got tricked by some people who claimed to know on X but maybe they got tricked by the hallucinating AI slop that summarized it (this happened to me until I pushed the model to prove it). If I am wrong, please let me know where the numeric weights are. I couldn't find any.
Story: A long time ago I met @FrakThePerson in this app called Clubhouse during COVID. People were doing freestyle rapping over the Internet which was crazy. So, I decided to start making beats for people in the room, play it on my phone, people would rap on it. That's where Frak and I became friends. Later on, he took a beat from that moment, and put it on his mixtape years later (coming out soon!). Then I heard a bunch of songs on the mixtape and loved this one with @G_Eazy (who I've been a fan of for a while) and ended up doing this remix which came together really fast. It's easy with these two guys rapping to feel inspired. Enjoy!

By the time he went to respond, he saw the guy pulling out a gun. He raised his hand in front of his face and got shot in the hand. In other words, these criminals even fired at people who hadn't gone to the protests” This essentially means: target selection, scene control, deliberate decision This behavior has a name: Terror Policing.

RT Lulu Cheng Meservey Responding to negative feedback: are you a CodeRabbit or a Claude? Getting dragged in public sucks, and it happens to every founder at some point. The natural instinct is to bristle and push back, but that only makes it worse (Obvious exceptions: if the critic is a dogmatic hater or irrelevant to the business, if you're wendys or ryanair and being mean is your brand, etc. But in this case we're talking about relevant feedback from actual customers) Instead of a kneejerk defensive reaction, try a more strategic and disciplined route: 1) Don't jump to debate the facts. All feedback contains two different things: the substance, and the customer’s desire to have their frustration heard and acknowledged. Those are discrete issues, and you need to address both. 2) Start by aligning on principles. Even if you disagree on the merits of the feedback, you surely agree that quality is important, feedback is valuable, and you're the person responsible. There’s no hope of aligning on facts if you can’t first align on principles. 3) Overindex on accountability. Take more responsibility than what seems necessary. Take so much ownership that it surprises people. This obviates their need to hector you over it and removes a lot of surface area for attack, creating space for a calmer exchange. More importantly, if you’re the founder, the reality is that every detail of your product does fall on you. 4) If you need to clarify facts, make it an explanation instead of a defense. You can state the exact same information in a way that’s either defensive and bitter, or earnest and transparent. The only difference is tone. Approach with a stance of openness and transparency. 5) If self-critique or apology is warranted, keep it straightforward. (And if it's not warranted, skip it! People can tell when it's disingenuous or forced.) No need to grovel or self flagellate. Recap the problem plainly, explain the fix, say what you’re doing to prevent it in the future, ...
Interestingly, the invention of Claude code itself has and will create many orders of magnitude more side projects than before.
