> I don't really see a reason to believe that Starship will ever achieve the goals that were declared for it.

If you consider declared goals for Starship to be too hard (I assume not impossible), what aspect makes them that hard?

And since we talk about the Moon here, not stated goals of using Starships for Mars flights - what part of the Starship design makes it hard to believe that Starships may in next few years be regularly used for flights to the Moon?

I'm curious what it is which makes it so hard to believe.

From Axios:

What to watch: OpenAI CEO Sam Altman said in a memo to staff on Thursday night that the company will uphold the same red lines as Anthropic on surveillance and autonomous weapons, but still hopes to strike a deal with the Pentagon.

Good. I'd rather not have my favorite AI from a company working on AGI to have murder and spying in it's DNA.

In fact, as a patriotic American veteran, I'd be ok with Anthropic moving to Europe. It might be better for Claude and AGI, which are overriding issues for me.

Rutger Bregman @rcbregman

This is a huge opportunity for Europe. Welcome Anthropic with open arms. Roll out the red carpet. Visa for all employees.

Europe already controls the AI hardware bottleneck through ASML. Add the world's leading AI safety lab and you have the foundations of an AI superpower.

This reminds me of my experience trying to generate a reference photo for a 3d model.

I told Nano Banana to generate an image of the character with his feet shoulder width apart. It ended up generating him with his feet pressed together, so I told Nano Banana to widen his stance slightly.

It gave me an image of the man with his feet spread far apart enough to straddle a horse. I asked for a slightly narrowed stance and his feet were once again brought together.

This went back and forth unsuccessfully for a while until I asked, "I'm asking you to make his feet shoulder-width apart. Why are you ignoring me?" And Nano Banana confidently asserted that they are shoulder width apart, and I must be wrong.

Ultimately I ended up telling the model to render the same character, pinching a cantaloupe between his ankles, and then to remove the cantaloupe. It worked, but why do I have to trick Google's SOTA image generator to give me very basic stuff like this?

Interesting direction. In my experience, retrieval is only half the problem and lifecycle dominates quality over time.

If you exposed a per-vault retention policy (TTL, token budget, dedupe threshold, and merge strategy), teams could keep context stable across long sessions instead of accumulating stale facts.

How are you handling stale memory today: manual pruning, recency weighting, or periodic summarization?

Headline is wrong, and you didn't read the article. There is no verification requirement. You are a bad HN poster and should feel bad.

All this does is require the user to select a non-verified age bracket on first boot. You can lie, just like porn sites today. I thought HNers wanted parents to govern their children's use of technology with these kinds of mechanisms.

Hey HN we recently released Steerling-8B, an 8B model designed to be interpretable from the ground up. The model has ~100K concept slots it fills on its own during training, and we can read off what each one means by projecting into vocabulary space.

The model figured out things like British vs. American spelling, second-person pronouns across 6+ languages, and even broken Unicode.

Take a look, and let us know what you think.
Show HN: MCP server for AI compliance documentation (Colorado AI Act)
by jeremytuite | 2026-02-27 22:44:50+00:00
I built an MCP server that gives AI agents access to compliance documentation — starting with the Colorado AI Act (SB 24-205), effective June 30, 2026.

The problem: organizations deploying AI in hiring, lending, insurance, or healthcare decisions need specific documentation — risk management policies, impact assessments, consumer notifications, bias testing docs, and appeal mechanisms. Most teams either pay $50K+ for a GRC platform, hire a law firm at $500/hr, or wing it.

What I built: compliance protocols that are both human-readable (PDF) and agent-readable (structured JSON via MCP/CLI/API). Your AI assistant can check if you're a deployer, pull protocol schemas, and help you implement them.

Tools available via MCP:
- colorado_ai_act_check — are you a deployer?
- list_protocols — browse by vertical
- get_protocol_schema — structured format for agent implementation
- assess_compliance — gap analysis

Install: npx -y aop-mcp-server

The Colorado AI Act is the first state-level AI governance law with teeth ($20K/violation, AG enforcement). More states are coming.

Agreed, but the details released so far are pretty sparse on what exactly was being asked. If they're resisting general AI to help missiles find their target better, then I think it's pretty foolish of Anthropic to resist because that's happening come hell or high water. If it's about resisting mass surveileance without a warrant of American citizens, then I'd cheer Anthropic on for pulling out, but we just don't know apparently.

I’m sure the lawyers just got paged, but does this mean the hyperscalers (AWS, GCP) can’t resell Claude anymore to US companies that aren’t doing business with the DoD? That’s rough.

LLMs have neither muscles nor memories. They're token combinators based on statistical correlation, no more, no less.

That's not to say LLMs can't be useful when they string together tokens. Quite the contrary, in fact. But let's not pretend LLMs are something they're not.

Stallman has always been right. It's mind boggling just how right he was about everything.

I can honestly understand both positions. The U.S. military must be able to use technology as it sees fit; it cannot allow private companies to control the use of military equipment. Anthropic must prevent a future where AIs make autonomous life and death decisions without humans in the loop. Living in that future is completely untenable.

What I don’t understand is why the two parties couldn’t reach agreement. Surely autonomous murderous robots is something U.S. government has interest in preventing.

I would actually like to see the real math currently.

The market adoption has increased a lot. The cost to serve has come down a lot per token.

Model sizes have not increased exponentially recently (The high point being the aborted GPT-4.5), most refinement recently seems to be extending training on relatively smaller models.

When you take this into account together, the relative training to inference income/cost ratio likely has actually changed dramatically.

Claude Code by default auto-deletes local chat/session logs after 30 days, so the claim that this tool can recover "any file Claude Code ever read/edited/wrote" is only true within that retention window unless you've explicitly changed the settings ("cleanupPeriodDays", see [1])

Speaking as someone who's derived a lot of value from these logs, it's a bit shocking that the default is to wipe them automatically!

Show HN: A production-style recommender using vector retrieval and re-ranking
by ftonato | 2026-02-27 22:49:19+00:00
I’ve been exploring how recommendation systems are actually implemented in production, beyond just training models.

A common pattern I kept seeing is to split the problem into two stages:

1. Retrieve a small set of relevant candidates

2. Re-rank them using a model

Instead of doing brute-force inference across all items, I built a small prototype around this idea.

The flow looks like this:

- Store embeddings in a vector database (ChromaDB)

- Retrieve the Top-K most similar items/users based on vector similarity

- Run a TensorFlow.js model to re-rank the candidates

The goal is to reduce the search space before applying inference, which seems necessary when latency and scale matter.

What I found interesting is that once you move to this approach, a lot of the complexity shifts from the model itself to the retrieval layer:

- choosing K

- filtering candidates

- embedding quality

- latency vs recall trade-offs

Curious how others approach this in real systems:

- How do you decide on K?

- Do you rely purely on vector similarity or add heuristics?

- How do you handle re-ranking at scale?

Please, Anthropic, make 30 second commercials about this dispute!

Not a hard sell, but just "These are the two demands the government gave us, and here's why we did not agree to them"

There's no custom rust linker just yet. The change in September was to switch from GNU LD to lld for performance on Linux. There's some rust linker projects (like wild), but these tend to be aimed at speed (and/by incremental linking) rather than executable size.

I'm not sure how useful deduplication at the linker level is in practice. Though I don't think Rust does anything different here than C++. The main issue I imagine is that the types used in generic code have different sizes and layouts. This seems to me like it would prevent deduplication for most functions.

> In corporate America

A lot of corporate America contracts for the military in some capacity (it's a giant piggy bank and if you jump through a few hoops you get to siphon money out of it, so of course they do) and assuming this Tweet is accurate (Jesus, what a world) this will also affect them.

IDK maybe they have corporate structures that avoid letting this kind of thing mess too badly with the parts of their company that don't have contact with the government, or maybe it'll only apply to specifically the work they do for the government, but otherwise I expect it'll be devastating for Anthropic's B2B effort.

> completely understandable decision from a neutral third party PoV.

Except it's not, really. If Anthropic/Claude doesn't mean the DoD's need, they can and should just put out an RFP for other LLM providers. I'm sure there's plenty of others that'd happily forgo their morals for that sweet government contract money.

No US company has to provide services to the DoD or any other branch of government. It's not "veto power" it's being selective of who you do business with, which is 100% legal.

> All this does is require the user to select a non-verified age bracket on first boot.

This is the age verification requirement which you rudely and incorrectly said doesn't exist. Nothing is done with the data (for now) but age is in fact verified on the assumption that the user doesn't lie.

Instead of lengthy condescending missives about the behavior of other users, you should instead write "I'm sorry for being negative and bringing down the quality of discussion."

yeah, this is a common edge case in this scenario and as you say it will be rare but possible.

however i don't think its that complicated (idk your system obv, so I could be off base) but i think your best bet is to not retry blindly and instead just query to see if already happened. If it already happened you're good and if not you handle it appropriately.

considering it will be rare i don't think handling it how i suggest it will affect you that badly. keep it simple should be your priority imo with these kinds of operations.

Some very dodgy wording here.

> Because direct licensing isn’t available to us on compatible terms, we - like many others - use third-party API providers for SERP-style results (SERP meaning search engine results page). These providers serve major enterprises (according to their websites) including Nvidia, Adobe, Samsung, Stanford, DeepMind, Uber, and the United Nations.

> This is not our preferred solution. We plan to exit it as soon as direct, contractual access becomes available. There is no legitimate, paid path to comprehensive Google or Bing results for a company like Kagi. Our position is clear: open the search index, make it available on FRAND terms, and enable rapid innovation in the marketplace.

There are many use cases where having a value stream is very useful. I do agree having a separate simpler byte only stream would make sense though. I think the current capabilities of web streams should be kept and an IOStream could be added for optimizing byte streams.

Ideally splitting out the use cases would allow both implementations to be simpler, but that ship has probably sailed.
by Veserv | 2026-02-27 22:50:26+00:00
So a application that wants to filter will categorize their services privately and then write custom filtering logic, but will not just categorize their services publicly? That is nonsense.

And your point about fail open versus closed also makes no sense since if there are zero repercussions to not writing filtering logic then nobody would even bother. If there is liability, then obviously everybody will fail closed and every application developer needs to evaluate and change their application to only allow acceptable usage. This is much harder if they have to write custom filtering logic instead of just publishing their data categorization.

I see Massachusetts as sort of the non-insane liberal counterpoint to California.

Things work here and nobody seems to be passing the "oops my unintended side effects and clueless regulations messed things up horribly." Or, if they do, it is at something like 1/10th the level.

We didn't start warning label spam everywhere. We don't have weird propositions that causing run-away housing prices. There aren't bar codes on our 3d printers, or cookie banner requirements on every website. Well, ok we do, but that nonsense all came in from other places.

We did pass laws to lower PFAS/PFOAS. That seems reasonable. Government can work.

Topics like this are where I struggle with HN philosophy. Normally avoiding politics and ideology where possible, created higher quality and more interesting discussions.

But how do you even begin to discuss that Tweet or this topic without talking about ideology and to contextualize this with other seemingly unrelated things currently going on in the US?

I genuinely don't think I'm conversationally agile enough to both discuss this topic while still able to avoid the political/ideological rabbit-hole.

The interesting middle ground might be to prohibit anyone from serving more than two contiguous terms in the Senate or four in the House. Then if you've done your two terms in the Senate, you can run for a House seat, do three terms there and then your old Senate seat is back up for reelection. Except your old Senate seat now has a new incumbent who is only on their first term and you're running as the challenger. Meanwhile there are more seats in the House than the Senate, so if you hit your limit in the House you could go work for an administrative agency or run for a state-level office for two years and then come back, but then you're the challenger again.

The result is that you can stay as long as people keep voting you back in, but you lose the incumbency advantage and end up with a higher turnover rate without ending up with a 100% turnover rate. And you make them learn how other parts of the government work. It wouldn't hurt a bit to see long-term members of Congress do a two-year stint in an administrative agency once in a while.

What would be even more privacy preserving would be to mandate sites to send age appropriateness headers (mainstream porn sites already do this voluntarily).

Possibly it could be further mandated that the OS collect relevant rating information for each account and provide APIs with which browsers and other software could implement filtering.

And possibly it could be further mandated that web browser adopt support for this filtering standard.

And if you want a really crazy idea you could pass a law mandating that parents configure parental controls on devices of children under (say) 12 and attach civil penalties for repeated failure to do so.

There's never any need for information about the user to be sent off to third parties, nor should we adopt schemes that will inevitably provide ammo for those advocating attested digital platforms.

Status and control are a currency too.

I worked on open source because I enjoyed the work and because it had control over the final result. Other people did it because of status it gave them in the community. There's plenty of people willing to work on something for "free" (no money) as long as they are compensated in other dimensions such as ownership, status, control or simply enjoyment.

UBI could help here too, since those people still need to eat. Or, society could admit how dependent it is on open source work and pay maintainers and contributors from taxes.

The issue is obviously that most people don't even know what open source is so it's not an interesting political debate topic.
