djoldman··on Claude Haiku 5.5
https://www.anthropic.com/claude-haiku-5-5#further-updates

This section makes the reader think: why would I not pick Sonnet 5.5 instead of Haiku 5.5?

djoldman··on EmbeddingGemma 2: An open, lightweight multimodal embedding model
Parameter count split is interesting:

740M total (270M text, 170M vision, 300M audio)

djoldman··on Subquadratic 3SUM and Subcubic APSP
> Claude, an AI model developed by Anthropic, discovered the algorithm that refutes the 3SUM, APSP, and Exact Triangle hypotheses. The authors then worked to understand, simplify, strengthen, and extend the algorithm, derive additional consequences, and make the presentation accessible. See “Acknowledgments and Methodology” for how the result was found and shared with the authors. The authors take full responsibility for this paper.

> Claude also verified this paper’s main results using the Lean 4 proof assistant with the Mathlib library.

djoldman··on Oracle Triggered the Implosion of the AI Bubble
The bigger story in all of this is the follow on to the answer to: "how do they plan to pay for it?"

They plan to pay for most of it through excess cash flow, aka profits.

Follow on question: "they make $100s of billions per year? what did they do with all that previously?"

Answer: share buybacks, nothing (aka put it in the bank), acquisitions.

These companies make a ton of money and have a ton of margin over expenses.

I had this directive as well.

I was told to point at someone and say, "YOU. Call 911."

djoldman··on Questions for believers in AI consciousness
TFA is a part of what seems like a never-ending series about concepts that lack a useful definition.

"Thinking" and "intelligence" and "conscious" have no testable definition or specification, therefore it's a complete waste of time to suppose that AI is thinking or intelligent or conscious.

I fear we'll be suffering through these useless semantic merry-go-rounds forever.

djoldman··on "I'm Embarrassed on Behalf of the Tech Industry"
Most of the problems are a result of 2 things: the US economic regulation regime and the weaknesses of human nature.

1. The US economic regulation regime allows one or a few companies to hold an amount/quality of power, beyond which the FTC is supposed to get involved and break up the companies so that power isn't concentrated. This exists because pure capitalism quickly results in one winner, which makes for zero incentive for it to compete/improve/lower prices/increase quality. The fear of anti-monopolistic action by the FTC is low enough and actual action is rare enough that lots of power is unchecked.

2. Humans like bright lights/shiny objects (gambling), feeling tribal/us-vs-them (rage bait wins, negativity drives engagement), are easily exhausted by or ignore options (overwhelming acceptance of defaults), etc.

The above, either in combination or separately, combine to drive low quality computer experiences. Marketing/advertising alone drives an incredible multiple profit compared to actual quality of product/service.

djoldman··on Greg Kroah-Hartman – Security in the LLM Age [video]
> So what all of mythos; that whole big marketing issue of 79 bugs came down to one hour of kernel development.

If you're someone at OpenAI or Anthropic and you truly believe what you're making could destroy the world, this is the kind of thing that isn't doing you any favors when it comes to convincing the public. The dissonance here is stark:

  - widely proclaiming that your new model is so dangerous it needs to be released only to select people, for safety
  - widely proclaiming the model easily found 79 bugs in linux, except that GKH says it took 1 hour to fix all of them because most weren't bugs and the rest were almost all completely trivial, unimportant, and/or not severe
It doesn't mean the model isn't dangerous or super capable but wow this makes it realllll easy to doubt it and any future announcement.
djoldman··on Meta Uses A.I. Data Centers to Avoid Billions in Federal Taxes
I don't understand. I wrote that one should assume that entities will do anything LEGAL.

I'm not saying we should assume they'll do anything as long as they believe they can evade punishment, although perhaps we should?

djoldman··on Meta Uses A.I. Data Centers to Avoid Billions in Federal Taxes
I could hardly agree more.

I would say that we get the one (public outrage at specific companies/people) but not the other (focus on the legislation). Unfortunately, the latter has the controlling direct effect.

djoldman··on Meta Uses A.I. Data Centers to Avoid Billions in Federal Taxes
For TFA, I propose:

"A Federal Law Gray Area Allows Meta a Potentially Massive Tax Break."

... or something similar.

The focus could be less about Meta and more about the law. It's not like there's something special about Meta. The vast majority of corporations would do this if it was profitable.

djoldman··on Meta Uses A.I. Data Centers to Avoid Billions in Federal Taxes
I wouldn't say the author thinks it is illegal. I think the author is reporting on Meta's tax approach that is "untested" and possibly will be challenged by the IRS.

Regardless, the overwhelming majority of the article is about Meta's actions: when, why, how. Very little of it is about the laws governing the taxes, who passed them, when, what's been proposed to amend them, etc.

djoldman··on Meta Uses A.I. Data Centers to Avoid Billions in Federal Taxes
As I've commented elsewhere: Isn't this a good example of it being more accurate to blame the system that allows the spending or influence?

The general assumption should be that at least some people/corporations will do ANYTHING that is legal as long as it is profitable.

djoldman··on Meta Uses A.I. Data Centers to Avoid Billions in Federal Taxes
In relationships between people one interacts with directly, I agree: there are "social contracts" that aren't laws that people in the USA generally follow. Knowing about them and not following them makes someone a jerk.

Wreaking "untold damage" sounds like something where a law should exist to prevent it unless there's some incredibly important counter benefit.

djoldman··on Meta Uses A.I. Data Centers to Avoid Billions in Federal Taxes
I see the article as almost obsessively focused on the details and intricacies about how Meta is attempting to avoid taxes, what the timelines are, who's involved, etc. It seems written to be read like a thriller almost: to what lengths could this evil corporation go to further their schemes? There seems to be exactly 1 paragraph about when, why, and how the laws in question came to be:

> The tax break dates to the first year of the Reagan administration, when Japan...

It seems to me that there could be a lot more discussion and analysis on what led to the laws, who was involved, efforts since to amend them, etc.

djoldman··on Meta Uses A.I. Data Centers to Avoid Billions in Federal Taxes
It often strikes me as quite the biased and one-sided take when a tax-paying entity is called out by the press for tax avoidance (NOT tax evasion, which is illegal). (yes TFA implies that Meta is breaking the law, I'm not talking about situations where entities break the law).

Previously we've seen "The Secret IRS Files" from Propublica as well as other coverage of tax avoidance that never resulted in tax evasion charges. Coverage wide enough that it's arguably safe to assume that no laws were broken because there was quite the demand for an enforcement response.

The funny thing is that a more accurate title for these pieces would be, "Federal Government Allows [tax-paying entity] a Massive Tax Break." And then the piece would be all about how the senate, congress, and president either explicitly wanted there to be this extreme tax loophole or was incompetent and allowed something they didn't mean to allow.

Folks are continually getting upset and riled up about players in the economic system instead of who and what makes the rules.

An analogous example: everyone got cranky about Martin Shkreli, mostly because he raised prices on Deraprim, although also because many would label him a brash jerk. But he went to jail for finance stuff, not raising prices. Why? Because raising prices in the way he did wasn't something the feds thought was illegal or wasn't something they thought he could be convicted of.

Folks get mad at Musk, Zuckerberg, etc... if they're doing something illegal, ok yea that makes sense. If folks are mad about actions that are legal, it makes zero sense to be mad at the actor. Be mad at the people/entities who created the legal loopholes and laws.

djoldman··on CS240 AI Cheating Retrospective
> This form must be completed .... Failure to complete the form will result in an unfavorable letter being sent to the Dean of Students along with further potential disciplinary action.

The above letter sent to a bunch of students.

> It is an open question whether this is reflective of their actual behavior or instead something that underscores the purported, and unintentional, potentially coercive nature of the form.

Sounds like the professor discovered (or disputes the possibility of?) the concept of forced confessions.

"Honest responses that align with our analysis": did the professor consider the possibility of dishonest responses that align with the analysis?

"Should you choose to do so and we determine that our original findings of AI/LLM usage stand" Not much needs to be said about that.

If the professor was confident enough about the analysis to send the letter, then all of the students getting the letter should have gotten an F and no letter at all.

djoldman··on Has Violence Against Teachers Become Accepted by Society?
Is it "accepted" by society? Answering that depends on the definition of "accepted."

Is it reasonably expected? Yes, definitely, if that means "much more likely than violence against non-teachers": a random K-12 teacher in the USA is ~2.5-7x more likely to be assaulted than a random person in the USA.

What happens if someone buys their iphone in the UK, sets their region to UK, then sets the region to USA? Can they then enable advanced data protection?
djoldman··on Cache-to-Cache: Direct Semantic Communication Between LLMs (2025)
Seems like fundamentally a cool idea but: KV is not context. if the KV cache gets evicted, you'd have to rerun the translation.

Seems like it could still help but also feels like one of those things where it becomes vastly more complex and difficult to debug.

djoldman··on Prediction: AI Will Collapse
> It must be impossible for AI to: make purchases you did not intend, send messages you did not intend, and access information you did not want to share.

Hrm. I'd say that all of these things are possible when using services of companies that are valued at billions/trillions in the stock market. So "impossible" might be too strict.

No need to be sorry.

My "no worries" comment was a bit tongue-in-cheek. Who knows how far the tech will go or how cheap it will get.

I mean the FBI / cops.
djoldman··on The safest job from AI may be writing
Presumably they mean HFT / "locals" / "sell side."

These folks compete in a reasonably zero-sum game.

djoldman··on Student teacher arrested for private Snapchat message
> "Snapchat’s algorithm didn’t get the humor."

Presumably, the actual text of the message was reviewed by a human? So the human(s) didn't get the humor either?

EDIT: by "humans" I mean the FBI / cops.
