> your body can simply take longer or less time to digest the food you put into it and extract more or less energy

Great point.

> If you're exercising more, sure, your body will make you more hungry, but it will also work harder to squeeze every possible calorie

I find when I only do light exercise, that I am less hungry than when I don't exercise. Perhaps because I get better sleep, I am less hungry.

All the dynamics are crazy.

I think this depends on what reasoning level your Claude Code is set to.

Go to /models, select opus, and the dim text at the bottom will tell you the reasoning level.

High reasoning is a big difference versus 4.5. 4.6 high uses a lot of tokens for even small tasks, and if you have a large codebase it will fill almost all context then compact often.

> You seem knowledgeable about this, so I'll take the opportunity to ask: if I install a malicious app and it manages to escape the sandbox and alter the system, my understanding is that it will be detected next time I boot it (because the image hash won't match). Isn't that true?

They're misrepresenting what has been said by GrapheneOS and also lack a good understanding of it themselves. They're definitely not a good source of information about this.

We’re probably settling into what they call a “hybrid regime”.

We’ll likely wobble between periods of relative stability, with about the amount of liberty and corruption we’re used to at the federal level, and more-authoritarian high-corruption periods like this one.

Breaking out of the cycle, I rate less likely than a full collapse into authoritarianism. I just don’t see a viable path to the kinds of reforms we’d need. And it’ll get harder the longer this goes on, as the rot of corruption affects state capacity, industrial capacity, and drives even more entrenched local corruption than we already deal with. Plus we’ve got multiple debt and cost crises about to slam into us full-force, over the next 1-3 decades.

But for now: hybrid regime.

"Opus 4.6 often thinks more deeply and more carefully revisits its reasoning before settling on an answer. This produces better results on harder problems, but can add cost and latency on simpler ones. If you’re finding that the model is overthinking on a given task, we recommend dialing effort down from its default setting (high) to medium."[1]

I doubt it is a conspiracy.

Repeating yourself doesn't make you right, just repetitive. Ignoring refutations you don't like doesn't make them wrong. Observing that something has already been refuted, in an effort to avoid further repetition, is not in itself inherently rude.

Any definition of intelligence that does not axiomatically say "is human" or "is biological" or similar is something a machine can meet, insofar as we're also just machines made out of biology. For any given X, "AI can't do X yet" is a statement with an expiration date on it, and I wouldn't bet on that expiration date being too far in the future. This is a problem.

It is, in particular, difficult at this point to construct a meaningful definition of intelligence that simultaneously includes all humans and excludes all AIs. Many motivated-reasoning / rationalization attempts to construct a definition that excludes the highest-end AIs often exclude some humans. (By "motivated-reasoning / rationalization", I mean that such attempts start by writing "and therefore AIs can't possibly be intelligent" at the bottom, and work backwards from there to faux-rationalize what they've already decided must be true.)

> One of the most irritating things about these discussions is proclamations that make it pretty clear you've not used these tools in a while or ever. Really, when was the last time you had LLMs try long multi-digit arithmetic on random numbers ? Because your comment is just wrong.

They still make these errors on anything that is out of distribution. There is literally a post in this thread linking to a chat where Sonnet failed a basic arithmetic puzzle: https://news.ycombinator.com/item?id=47051286

> Good thing LLMs can handle this just fine I guess.

LLMs can match an example at exactly that trivial level because it can be predicted from context. However, if you construct a more complex example with several rules, especially with rules that have contradictions and have specified logic to resolve conflicts, they fail badly. They can't even reliably play Chess or Poker without breaking the rules despite those extremely well-represented in the dataset already, nevermind a made-up set of logical rules.

Interesting crash list. A bunch of low speed crashes, one bus hit the Tesla while the Tesla was stationary, and one 17mph into static object (ouch).

For those complaining about Tesla's redactions - fair and good. That said, Tesla formed its media strategy at a time when gas car companies and shorts bought ENTIRE MEDIA ORGs just to trash them to back their short. Their hopefulness about a good showing on the media side died with Clarkson and co faking dead batteries in a roadster test -- so, yes, they're paranoid, but also, they spent years with everyone out to get them.

One concern I have is that this async/await approach is not "AOT"-enough like the Triton approach, in the sense that you know how to most efficiently schedule the computations on which warps since you know exactly what operations you'll be performing at compile time.

Here with the async/await approach, it seems like there needs to be manual book-keeping at runtime to know what has finished, what has not, and _then_ consider which warp should we put this new computation in. Do you anticipate that there will be measurable performance difference?

And I'll just use this opportunity to recommend David Graeber's "Debt: The First 5,000 Years" - a wonderful book about the history of economy, demonstrating how it always boils down to effective use of debt.

There are tons of great parts in it, but one that really stuck with me is his analysis of the social dynamics whereby when someone brings you a gift or otherwise does something expensive for you, you are temporarily in debt to them, and the polite expectation is that you always pay it back in a way whereby you give more than you owe, such that they will then be in debt to you (generally for approximately the same amount), and the relationship can continue oscillating, with each of you being in debt about half the time. Paying back exactly what you were given and not a penny more is thus considered to be an indication that you want to discontinue the relationship.

Russia's military force currently relies on men willing to die for money. That could change. But Putin seems reluctant to force the general population to die in Ukraine.

Classic economic theory suggests that the amount you need offer to people willing to die goes up over time.

For Ukraine the main thing is to get to the point that Russia doesn't attack any more. There is no need for Ukraine to concur any part of Russia. Even getting the currently occupied land back is mostly optional.

Back when I ran a WoW guild, the first sentence in our recruitment post emphasized the importance of reading the whole post (because the way to access the application form was to click the only smiley in the post, and this detail was mentioned in the last paragraph).

Most people did not read the post, which was immediately evident from how they posted their application by copy-pasting and editing an application posted by someone else before them.

I built Cortex to solve the most frustrating part of AI coding assistants: session boundary amnesia.

You spend 2 hours with Claude Code. It understands your codebase, knows why you rejected MongoDB, remembers your authentication decisions. Then the session ends. Total amnesia.

Cortex is an event-sourced memory system that captures context automatically and projects it into each new session:

- Three-layer extraction: structural (tool calls), semantic (decision patterns), self-reporting ([MEMORY:] tags)
- Token-budget-aware briefings (~0.2% of context window)
- Progressive tiers: JSON → SQLite/FTS5 → embeddings/vector search → MCP server

A/B testing results (18 vs 11 sessions):
- Cold start: 9.0 min → 1.4 min (84% reduction)
- Decision regression: 0.5 → 0.1 per session (80% reduction)
- Continuity score: 2.9 → 4.7 (out of 5)

713 tests. Python. Open source.

Nah, Waymo is much safer than Tesla today, while Tesla has way-mo* data to train on and much more compute capacity in their hands.

Camera-only was a massive mistake. They'll never admit to that because there's now millions of cars out there that will be perceived as defective if they do. This is the decision that will sink Tesla to the ground, you'll see. But hail Karpathy, yeah.

I think the problem is that there is not much data presented in this article - or other articles of that kind.

Systems are resilient - until they are not, and exhibit sudden factures and fast collapse.

The question is not whether Russia collapses or not, but who would be making profit from such a scenario, and who is keen on keeping the current state of affairs.

When one learns about graphic design, one ends up obsessing about these kinds of things. "These text lines need a tiny little bit more of space"... "Those margins are slighly too small"...

Thanks for correcting; I know that "loss function" is not a good term when it comes to transformer models.

Since I've forgotten every sliver I ever knew about artificial neural networks and related basics, gradient descent, even linear algebra... what's a thorough definition of "next token prediction" though?

The definition of the token space and the probabilities that determine the next one, the hidden layers / feedback loops, all of this was intentionally not present in my answer, I'm also unable to define it properly.

I was using the term "loss function" specifically because I was thinking about post-training and reinforcement learning. But to be honest, a less technical term would have been better I guess.

For a decade, B2B SaaS growth has been split between Sales-Led (scale headcount) and Product-Led (scale free tiers). Both are fundamentally linear. SLG scales with team size. PLG scales with product surface area.

AI-Led Growth removes the linear constraint. Pipeline generation becomes a compute problem. AI agents handle identification, enrichment, scoring, outreach, and qualification. Humans handle the high-judgment conversations that close deals.

The technical requirements are different from traditional sales tooling. Real-time enrichment waterfalls. Event-driven automation from intent signals. Confidence scoring on every contact record. Multi-provider data validation before any outreach fires.

Currently the viable model is hybrid: ALG + SLG. AI generates and qualifies. Humans close. The economics favor this heavily over pure SLG because compute costs decline while headcount costs increase.

Based on our audit data (127 B2B SaaS companies), 67% have adopted AI in GTM but only 23% have connected it to measurable pipeline workflows. The gap is almost entirely an infrastructure problem, not a tooling problem.

FWIW whisper.cpp with the default model works at 6x realtime transcription speed on my four-core ~2.4GHz laptop, and doesn't really stress CPU or memory. This is for batch transcribing podcasts.

The downside is that couldn't get it to segment for different speakers. The concensus seemed to be to use a separate tool.

I observed this myself at least 10 years ago. I was reflecting on what I had done in the approximately 30 years I had been programming at that time, and how little had fundamentally changed. We still programmed by sitting at a keyboard, entering text on a screen, running a compiler, etc. Some languages and methodologies had their moments in the sun and then faded, the internet made sharing code and accessing documentation and examples much easier, but the experience of programming had changed little since the 1980s.

This isn't a lock

It's more like a hammer which makes its own independent evaluation of the ethics of every project you seek to use it on, and refuses to work whenever it judges against that – sometimes inscrutably or for obviously poor reasons.

If I use a hammer to bash in someone else's head, I'm the one going to prison, not the hammer or the hammer manufacturer or the hardware store I bought it from. And that's how it should be.

Claude invented something completely nonsensical:

> This is a classic upside-down cup trick! The cup is designed to be flipped — you drink from it by turning it upside down, which makes the sealed end the bottom and the open end the top. Once flipped, it functions just like a normal cup. *The sealed "top" prevents it from spilling while it's in its resting position, but the moment you flip it, you can drink normally from the open end.*

Emphasis mine.

So several sources report this. I assume this may be more "realistic"
than in the last 3 years ago or so.

My problem with this is that many of these "news media" have a certain
propaganda spin. Yes, Russia's propaganda puts any other propaganda
to shame, but that does not mean others don't use propaganda either.
The most prevalent change is how suddenly in Europe, more debt will
be made by upgrading arms. I am not saying this is not understandable,
so I am not necessarily against that; in fact, Europeans need a
nuclear arsenal under EU control anyway. But at the same time one
should not blindly adopt propaganda used by others. One always has
to look what happens to taxpayer's money or who finances something.

No. And I think you probably already know that; facetious rhetoric is not the norm here. Git is not a web-based GUI capable of managing users and permissions, facilitating the creation and management of repositories, handling pull requests, handling comments and communication, doing CI, or a variety of other tasks that sites like Codeberg and Forgejo and GitLab and GitHub do. If you don't want those things, that's fine, but that isn't an argument that git subsumes them.

This notice was published as a flagrant act of unlawful retaliation against late night shows for criticizing the sitting President. I think it's misleading to present it as a legitimate action, even if the Trump regime might attempt to enforce it and courts might uphold that enforcement. As the only non-regime FCC commissioner remaining has pointed out, the FCC specifically did not engage in the actual rulemaking procedure that's normally required to change these rules, because if they had their retaliatory motivation would have been a huge obstacle.

Not so experienced with Claude Code, but the web version does the job for me. I mean, I don't create very complex stuff for others (mostly websites and simple apps) but it did some things that I am proud of (I'm not a dev - have some exp with python, but even that is really basic stuff. So, here's what I do (makes it really easy to do stuff (at least simple stuff I do):
- Start a new project and discuss every single detail about it with Claude.
- Tell it to write a txt or pdf summary of everything and place that file in project knowledge.
- After that tell it to give you a complete project structure and create it
- Then simply start populating the files.
- Place each file in your project knowledge so it can see it
After this it's just debugging which mostly goes smooth as well

I've been playing with it for almost two years now, and this is what gets me there. ChatGPT never got even close to it.

BUS Core is a local-first back-office app for small makers: inventory in/out, simple BOM/recipes, and an audit trail of every change.
Built it because spreadsheets drift and I wanted “why is this number wrong?” to have an actual answer.

Runs locally (no cloud required). Install via Windows EXE (code-signed), Docker, or CLI.

Downloads + hashes: https://buscore.ca/downloads/

GitHub releases: https://github.com/True-Good-Craft/TGC-BUS-Core/releases

License: Core is AGPL. Commercial license available for orgs that can’t use AGPL.

Questions: What’s the minimum you’d need before you’d trust inventory counts? And would you prefer explicit workflows (predictable) over automation (fewer clicks)?

One thing I wonder is why design of experiments (DOE) methodology is so seldom used for these things.

Statisticians and operations researchers have spent a hundred years deciding how to do as few experiments as possible to tweak parameters in the ways that give the highest impact with statistical basis that the selections are good.

In the language of information and decision trees, these experiments are trying to in some sense “branch” on the entropy minimizing variables.

That makes sense. I play Arena a bit, but have always rejected the monetization model of not allowing players to pick what cards they want easily or play with proxies or something similar for casual friend games. I have absolutely no interest in their competitive game modes. I was slightly interested in the idea in the early days of buying boosters and getting arena codes, but they messed that up pretty bad and paper magic as a whole has been turned into a game of milking whales similar to predator mobile games or apps. The end result is Arena is something I will jump on to fool around sometimes every few months and remember why I don't want a second part time job.

I am both pro and against this at the same time. I love the idea of tracking it as an aggregate, but I hate the idea that the kid may end up being stuck on some vibe coded idiocy and unable to move on, because of it ( I still shudder at some of the ridiculous math tests in college that could not account for the right answer, but not in the exactly right format that was not disclosed as expected ).

I am not even suggesting in person teaching is the only solution either. I am currently dealing with, apparently, my kids teacher, who, well, kinda checked out, but as much I am happy for her being able to retire soon, I am not sure why my kid has to suffer academically.

What I am saying is, there is room for AI. What I worry about is, people are idiots and anything half-useful will be neutered and kids will have all the drawbacks of heavy surveillance and zero to show for it.

> If your phone is not supported by GOS, you should look carefully and compare between /e/OS and Stock Android.

If you have an iPhone that's still supported, you have strong privacy and security. If you have a phone that's not an iPhone and not supported by GrapheneOS then you likely have a phone with atrocious privacy and security regardless of OS choice. If people can afford to get a secure device with years of proper support remaining then they should do that rather than using an insecure device with a sidegrade for privacy and security using a problematic AOSP fork. LineageOS is far less problematic than /e/. If people want to switch the OS to something else due to the OEM abandoning it or to avoid Google Mobile Services they should use at least use LineageOS which is less of a privacy and security downgrade from OS. LineageOS does not fully maintain the privacy and security of AOSP or fully keep up with updates but it's a lot less bad than /e/. Most alternate OSes are forks of LineageOS to reuse their work on hardware support and nearly entirely make privacy and security worse, not better, so why not use the upstream project instead?

> I had a Fairphone 3, and after 5 years, /e/OS was outdated by 4 years w.r.t. the manufacturer updates. In other words, Stock Android coming from Fairphone was more secure than /e/OS on that Fairphone.

It's important to note that an alternate OS depends on the OEM for firmware and in practice much more than that including kernel and driver updates. It's theoretically possible to replace the kernel and drivers with much different ones but it's not done in practice by alternate AOSP-based operating systems. If the device is abandoned by the OEM then you aren't going to have a secure device.

/e/ lags far behind on standard privacy and security updates everywhere but misleads users with an inaccurate Android security patch level along with many inaccurate privacy and security claims. LineageOS is much better than the fork of it by /e/ and does much less to mislead users, although it still has the inaccurate Android security patch level and many people still wrongly believe they're getting patches they aren't after the OEM dropped support.
