It's a problem I've spent a lot of time on, just not through the products marketed like temporal. I commented on the article because it's about program replay with checkpointing which is similar to what I worked with/men

Well, you have to either capture/eliminate/persist side effects and control the environment tightly, or it's limited in what it can do. In a distributed or concurrent system, for full granularity, that can require specialized

Good model. Anybody interested in actually training models or designing agentic systems should be doing this. My company started around working on this problem because it's the basis for how you train programming models/reliably d

Cars use AI for steering control (et al) and technology very similar to RLVR (hold the RL), eg property-based testing and formal verification, to prove the soundness of their embedded systems. Most of us in San Francisco trust Waymo with ou

But when nobody will die from your decision (and to be clear I think security is extremely important, but moreso for banking/healthcare than a private wow server), then “shoddy” becomes a matter of reputation/taste vs value/m

Strong agree. I think the fundamental challenge of working in fields that increasingly become AI-enabled will be the ability to understand and direct large or intricate systems without prior knowledge/the advantage of having built the

They're not selling it to you/it doesn't come out of your salary? They're selling it to your employer. You're literally not even the customer for this product. There's no need to get angry that they're cha

I genuinely think big tech co's top leadership have very sophisticated strategies/positioning that they simply cannot communicate or explicitly canonize due to their position as spokespeople for the company (and society writ large

I’m pretty sure if you asked my mom what problems AI could help solve for her, navigating website’s purchasing/account flows and directly answering questions about the contents of her email would be #1 and #2. And my mom doesn’t use AI

For the most part I feel the same way, and actually think it has the potential to completely change how e-commerce/web browsing work once it plays out, to the benefit of the client/consumer. But, I can definitely see a fair argume

I think they just want to show you ads and help you buy stuff. The incentive is actually to keep the data to themselves so they can monetize access to it via ads. The shopping experience is significantly less hostile than Amazon’s 1P digita

Try asking it to find a good deal for you for <item> across multiple sites. Then tell it to use the browser to navigate through the two most promising sites to confirm pricing and availability, and prepare comprehensive breakdown with

The inline browser the agent uses that you can take control of or watch is awesome! This is something I built a lot of tools to do in the past year (including a similar inline UX/image + click pass through) but having it Just Work in a

How exactly do you think Bill Gates at peak Microsoft is going to fix this given "it's 100% on him?" And do you think the guys on the line are the ones on this email thread? This is immensely more "ownership"/i

The way I process this kind of content is by skimming or ctl-Fing for the material I'm interested in reading and usually just reading the example code or the specific explanation for the content I'm after For example this site ran

That's fair. C is very old and used for almost all hardware so I think while you can make the argument that "only clang and gcc extensions asm blocks available like that, and intrinsics are only available through vendor-specific h

Sure, but then you're really arguing that the ISA no longer maintains 1:1 instruction-level implementation and that this is the definitive quality of whether or not something is low level, to the point that any deviation from that mode

by weitendorf 9d ago
This is such a pedantic point IMO. C is low level because it makes it very easy to work with machine language/assembly and do stuff like this (LLM assisted example follows): int main() { __m512i vecA = _mm512_setr_epi32(0,1,2,3

Gotta say this site is killing it in the LLM-written technical blog SEO game the last couple years, they're consistently able to dominate (and actual deliver in spite of the LLM-isms) SERP for a set of technologies that very closely al

Strong agree, but I also think some roles in big companies (for me, infrastructure) or in certain industries (eg trading/finance) can help build the same understanding without as much of the variance/raw exposure to bottom line. N

Sounds a lot like Spark before it became so enterprise-focused. Back in my day we wrote scala to run our queries, and once we figured out how to get our compiler and runtime set up, we liked it! I’ve been getting into Postgres recently and

This has been driving me crazy ever since I started using protobuf/grpc and realized more major tech companies (in the cloud/infra/data world at least, and a lot of other SAAS) were using it or something similar (eg capn prot

Anthropic’s revenue run rate just hit $50B, in a market that didn’t exist 5 years ago and was 10% of its current size 1 year ago. They are, by far, the fastest growing company in human history. The demand for “rockets” has been pretty high

You 100% can finetune or adapt/build on top of models, and specialize them or extend their capabilities. That’s literally what post training is. The problem is that “finetuning” was a 2023 AI FOTM associated with products/demos th

This is an oversimplification: more data makes models smarter ceteris paribus, but mostly only because auto-regressive training (where most of the general knowledge comes from) is essentially compressing information that can be recalled lat

I think it's much simpler than that, they are indeed trying to counter against sycophancy and models lying (the decision whether or not to lie to the human user, take shortcuts, etc. comes up in their thinking traces pretty commonly II

Frontier labs are not a monolithic entity. There is a clear self-verification/difficulty ramp in cybersecurity, and it is a very valuable as a skill both offensively and defensively. So it is absolutely certain that someone, somewhere,
