What I meant to say was "asymptotically approaches infinity" for 'f(x)' at some limiting value 'x' and thus a left/right mirroring of the function. I shouldn't assume people know I mean vertical just because I say asymptotic, so thanks for catching that imprecision in my wording.

As you probably know, horizontal asymptotes are never what we think of as the 'problematic' parts of Relativity, because when something approaches a constant that's never something that breaks the math.

The Schwarzchild metric, being a relationship of 6 different variables I think, has some relationships that go to infinity asymptotically at the EH radius and some things that approach a constant at that radius, so it's an example of the kind of asymptotic I was talking about _and_ one like your "horizontal" example.

Who says progressives aren't bothered by this?

Every leftist I know believes that education should be free and universally accessible. That holding capital (especially with the intent to make more capital, which is what an endowment is) is morally wrong. And that we should tax wealthy people and corporations to fund things like healthcare and education.

Constructing a strawman like this (inventing a position that progressives do not hold) and then trying to point out the hippocracy in that position is classic logical fallacy territory.

It's exactly what the entire campaign platform you voted for was: unprincipled, random bullshit designed to stoke an angry, bigoted, ignorant base.

I can respect principled patriotism and fiscal conservativism, but voting for an icon of xenophobia, illiteracy, and graft and expecting anything but that is kinda...

Also if you actually gave a shit about containing China, it would probably be in your best interests to vote for a candidate who doesn't base their campaign on alienating the entire rest of the free Western world while simultaneously denigrating and disrespecting the armed services... but what do I know.

Does Xata allow multiple "projects" or databases to share the same compute? As in, can you have a xata.medium with 3 databases running on it, or do you have to do run 3x xata.micro (or other size)?

Also, are there a minimum number of nodes required for PayG (not on-prem)?

I had to write off Xata (Now called Xata Lite) in the past due to the complicated pricing/plans while not being sure it did what I needed. But the new pricing is understandable and with Neon's acquisition I want to know my options.

EDIT: I missed this section at the bottom since I was already off reading other parts of the website:

> Are you looking for a simple, serverless, no-frills Postgres hosting for your side project, prototype, non-profit or vibe coded app? Xata Lite offers a generous free tier and per-storage pricing.

> Are you a Startup, Scaleup, or Enterprise that is running Postgres at scale? Then the new Xata Postgres platform brings you all the benefits outlined by this blog post.

Hmm, as much as I hate being lumped in with "vibe coded apps" I think Xata would only want me on Xata Lite. I'm not running Postgres "at scale". I do want a no-frills Postgres hosting but Xata Lite's pricing is annoying and hard to guesstimate.

Given a choice between a street where the cars are stuck in 2km/hr traffic and I'm passing them with a less than foot (0.3m) gap, or a street with 70km/hr traffic where they're passing me with a 1 meter (3 foot) gap... the former feels a lot safer.

Admittedly these streets aren't usually close together (either in time or space), but I've certainly biked on both.

Still, imperfect data can be better than no data.

If you want to argue against inequality, make that argument on its own merit without hijacking climate change and using it as a stalking horse.

Climate change is its own problem. Physics doesn’t care what our gini coefficient is. A more equal society that emits too much carbon still has this problem.

A decarbonized society powered by renewable and nuclear energy could still have too much inequality.

So far, I’ve catalogued over 6,000 MCP servers.

If you’re interested in the next layer beyond just discovering MCP servers, I’ve been working on https://ninja.ai — an app store for AI assistants to connect to tools via MCP, without needing to touch the command line. Think one-click installs for pipes that let agents actually do things like triage email or book Ubers.

Would love feedback if you’re experimenting in this space too!
Show HN: Mouse Escape – A game I made with my dad
by EvilDeadlyMice | 2025-05-18 00:40:57+00:00
Hi HN!

I'm a 4th grader and made this game called Mouse Escape with my dad. It's kind of like Pac-Man, but you play as a mouse escaping from humans and eating cheese! We made it together using AI and it only took 1 hour. Would love if you try it and tell us what you think :)

Play here: https://www.roadcrosser.com/mouse-escape

Thanks!

75 years ago, universities were cautious about accepting Federal funds due to this specific possibility. It worked out. Not it isn't.

Federal funds comes with strings attached and administrations change. If the usefulness of the work has proven itself now, then other sources can fund it. This won't really be controversial or require grandstanding or debate soon, because it will be the status quo.

Yes, its also disruptive to many programs to cut off funding in this way. I think decoupling is for the better. This university daytraded tax free up to a $50bn endowment, for a rainy day. They just need to get liquid and plug the budget gap, which they are starting to do. Donors and other sources can be leveraged too.

I heavily disagree with this one. On first glance what you say feels true, but there are so many mega popular people now that you will never know of despite even being from the same country. People with dozens of millions of fans, selling out arenas doing multinational tours and you won’t know them at all.

But everyone knows Britney Spears, even if you were never in her target demographic. This sort of global fame now requires so much more to reach because of how many are really locked into hyper personalized online experiences. I used to be able to reference the latest big movie or show and people would know, now that’s mostly turned into an explanation that the movie or show even came out and exists.

> With the PSX... so-so. Yes, it could match maybe a Pentium 90 almost 100, but a MMX pentium with 3DFX would stomp it

Pentium much faster than MIPS CPU for game logic, 3dfx 50 MPixels/s fillrate matches Playstations 60 MPixels/s, Pentium FPU tho is no match for Playstation GTE 90-300K triangles per second meaning you would have to rely on CPU power alone for geometry processing (like contemporary Bleem) resulting in 166-233MHz Pentium minimum requirements. MMX would be of no help here, it was barely used in few games for audio effects.

Progressives are busy being bothered by other things like transgender and autistic people being demonized, womens' rights being repealed, resegregation, the return of child labor, Nazis being cool apparently, the chilling effect of right-wing oppression and censorship causing the erasure of gay, female and non-white people from history and the public record, book bans and the whole "kidnapping political dissidents to foreign concentration camps" thing. But sure, we can add "rich assholes don't pay enough taxes" to the pile if you want.

Better question is why aren't conservatives bothered by any of this?

Italy? You mean where it is illegal to immediately deport someone to their own country if they can show they would be in danger due to EU and International law, and if safe, will be sent to a third country or back to their own country and allowed to apply? Or were you just trying to throw out an example hoping no one would know better about the difference between this, and sending people to third-world torture camps?

Advising the opposite to humans does not make sense. 13 words is already tiny to convince someone. The choices I was thinking were restricting LLM word count and increasing human word count. The goal is specifically to make them more comparable.

The given study does not show any strength of humans over LLMs. Both goal metrics (truthful and deceptive) are better for LLMs than humans. If you are misinterpreting my advice as general advice for people not under the study's conditions, I would want to see the results of the proposed rerun before suggesting that.

However, if length of text is legitimately convincing regardless of content, I don't know why humans should avoid using that. If LLMs end up more convincing to humans than other humans simply because humans are too prideful to make their arguments longer, that seems like the worst possible future.

I know I am an outlier case, but I am unable to function in society (or even individually) with an unrestricted smartphone. I'll literally not eat, not drink water, not sleep, miss all my classes, final exams, I'll miss the plane I booked a month earlier. I am 20yo, not a child either, but I have AuDHD. For years now I've implemented (often custom) solutions that allow me to use WhatsApp and $BANK_APP on a smartphone without having access to any sort of infinitely scrollable content. I'm living a fine life today - a moderately successful college student. Give me an unrestricted smartphone and you wouldn't be able to recognize my face after 3 days. In a week I'll likely be sick due to decreased immunity because of poor sleep, lack of nutrition & hydration and lack of self-care.

I don't think I'm alone in this, I've certainly seen similar anecdotes over the years. People who literally can't live with access to unrestricted smartphones - we exist. I'm glad to see these sort of "Alternative Device" movements - it surely is my longstanding dream to build a company that produces just that, a smart device you can't abuse, a bicycle for the mind with support wheels. Not everybody is healthy enough to ride a normal bicycle - people with disabilities will fall over and injure themselves if you put them on one, or worse, if you force them to use one.

I understand the self-control aspect - I'm trying to build it with various approaches. I hope I'll get it figured out before my 30s. It's something so many healthy neurotypical people take for granted, yet there is a minority who just can't.

I'm not of the academic type and this type of vocabulary quickly loses me. Lots of words to describe something that, at its core, is pretty simple. Mind twisting, but simple.

Infix notation parsing happens in ast.fs[1]. It parses tokens left to right and builds a tree (the structure is Lisp-like cons) describe the expression in such a way that expr.fs[2] then just has to recursively process the top tree node to have proper codegen.

In other words, operator precedence, prefix/postfix operators, etc. are all considered in ast.fs. Once in expr.fs is reached, all those things have been processed.

AST tests[3] give a good example of what ast.fs does.

I'm not sure I'd say that Forth being stack-based particularly help there. This logic is more "recursive-based" than anything. Lots of recursion all around.

On the flip side, accepting this funding has allowed for a lot of research to progress. Sometimes those strings attached still lead to a net good. Obviously, you should always have a plan for "what if this source of funding goes to zero, suddenly", and be prepared to walk away if needs be. But it's hard to imagine what university research would be like if they didn't accept Federal funding. (Much, much weaker, I'd imagine.)

Yep, and I think a lot of people who’ve tried it would agree. I’ve heard the same from others too, and I believe it.

I don’t know what typical display latency of just browsing files with a monitor these days. I’d guess it’s probably a few frames, and I’d bet we would be able to feel the difference between 3 frames of latency at 144hz and 1 frame of latency at 144hz. I’m also curious if mouse cursor motion blur would make any difference.

> I would prefer more defense spending to ensure the military inferiority of China.

How much do you believe each country spends on defense?

See: https://en.wikipedia.org/wiki/List_of_countries_with_highest...

Based on that, the US spends more than the remainder of the top 10 countries combined, most of which are allies.

The US could cut its defense budget in half and still be spending more than China and Russia (spots 2 and 3) combined.

Hey, thanks so much for checking it out, and really appreciate you scheduling a call!

That "no results" issue typically happens when the targeting criteria are too narrow or a specific region/industry has lower coverage in the lead dataset. I’ll walk you through how to get results fast on the call, and we’ll make sure it works smoothly for your use case.

Looking forward to chatting and getting you set up!

If you prefer a summary:

Key Allegations: 1. Hostile Environment: The complaint describes a campus atmosphere where pro-Hamas students and faculty have organized demonstrations featuring antisemitic slogans and calls for violence against Jews and Israel. These protests have reportedly disrupted classes and occupied campus spaces, creating an environment of fear and intimidation for Jewish students. 2. Administrative Inaction: Despite numerous complaints and reports of antisemitic incidents, the university administration is accused of failing to take appropriate disciplinary actions against perpetrators. The plaintiffs argue that this inaction amounts to deliberate indifference, exacerbating the hostile environment. 3. Double Standards: The lawsuit claims that Harvard enforces its anti-discrimination policies selectively, protecting other minority groups while neglecting the safety and rights of Jewish students. This alleged inconsistency is presented as evidence of institutional bias. 4. Faculty Conduct: Certain faculty members are accused of promoting antisemitic rhetoric in their teachings and public statements, further contributing to the hostile climate on campus. 5. Failure to Uphold Policies: The plaintiffs contend that Harvard has not adhered to its own stated policies on discrimination and harassment, thereby breaching contractual obligations to its students.

Legal Claims: • Violation of Title VI: The university is accused of failing to prevent discrimination based on race, color, or national origin, as mandated by federal law. • Breach of Contract: By not enforcing its anti-discrimination policies, Harvard is alleged to have breached its contractual commitments to provide a safe educational environment. • Breach of the Implied Covenant of Good Faith and Fair Dealing: The plaintiffs argue that the university’s actions, or lack thereof, violate the fundamental expectations of fairness and protection owed to students.

I couldn't care less about Anthropic or MCP—as I noted, I'm a critic of MCP—but pedants bug me quite a bit especially when they're wrong.

> The API is fed into the LLM as context, the response is part of the output.

So you implement tool use by feeding an API into the LLM as context in order to get it to produce call parameters. Got it.

> Whether you pass that output through another layer of LLM is trivial. And even if you do, the "context" in that case would be only the response

So the output of the tool when called with those parameters can be fed back into the LLM as further context. Got it.

Given the above, it seems that we agree that tool use is implemented entirely by giving selected bits of context to the model.

With that in mind, if one were to design a protocol that makes tool use plug-and-play instead of something that has to be coded by hand for each tool—a protocol designed to allow a model to discover tool APIs that it might want to bring into context and then use those APIs to bring their outputs into context—it would be reasonable to call said protocol the Model Context Protocol, because it's all about getting specific bits of Context into a Model.

I'm not sure why the word "context" is the hill you decided to die on here when there is so much else to pick on with MCP, but it's time to get off the hill.

The main purpose of HN is to be a place for discussing things that appeal to intellectual curiosity. This is pretty much the opposite of topics that “everyone has lots of feelings” about.

Moderators and longtime top contributors to HN come to recognise that these regular dramas about politics and culture wars bring out the worst in people, and lead to the very worst discussion threads we see on HN, precisely because “everyone has lots of feelings” about them.

It’s not wrong for people to have strong feelings about these topics. They're important issues, we get that, and that's why we try to be at least somewhat accommodating of discussions about them.

But when they routinely turn out to be the worst discussions we ever see on HN, and start to turn HN into something very different from what it is intended to be, we think that maybe these discussions should happen on the many other places that want to attract and encourage them, and not so much on this little corner of the web that’s trying to be something different.

Or maybe people are just overeacting. In the 1950s there was a movement that claimed that comic books were evil and rotting kids' minds. When I was growing up in the 1970s and 1980s it was TV. Then it was video games. Now it's social media, Kids like to do things that (at least to parents) look like wasting time. But if the parents look back to their own childhoods, they weren't using their time that productively either.

Could be, but considering that you have some police/government departments/public entities using this provider, it wouldn't be wise to leak their own data to everyone in the open like this.

On a side note, it's not the first time I've read a comment like the one you left above here on HN. As someone that lives in the UK, there seems to be a disconnection between what you guys write and what I see and experience daily. You make it look like no one can say anything or that this is a war zone... Don't take this the wrong way, but I recommend checking other news sources too because your view of the UK seems to be a bit "distorted".

A simple example is I have a series of three ordered connected things.

I called the first one “pre” since it “precedes” the others.

I called the last one “pro” since it “proceeds” from the others.

These are somewhat poetic/whimsical terms, for an abstract arrangement, but it’s nice to have good terms even for non-serious stuff.

I couldn’t come up with an equally concise term for the middle.

Claude came up with “per” as in “through” for the middle thing.

Couldn’t be more fitting.

We've already had over 1000 prompts shared and thousands of people using it. It's just as much about discovering cool ways to use AI that other humans share that you may not have thought of.

You can search for prompts related to something and find ones that are valuable without needing to write an effective prompt yourself. example marketers are searching 'marketing' and finding useful prompts contributed by other people.

According to the article you linked:

> ... the National Association of College and University Business Officers issues a report on ... where the money [endowments] generate ends up. ... About 48 percent of investment income went to student aid ... about a quarter of the money ... went to academic programs and maintaining facilities.

To claim it's a "tax dodge, and nothing more" without elaborating is absurd.

I won't argue further with someone more interested in inflammatory statements than actually discussing.

Sadly I think the ship has sailed and Rust has hit critical mass now. Personally I find it aesthetically awkward, but for Python integration and tooling it seems like Rust has become the default C replacement. You would think Python devs might have preferred something more superficially Pythonic like Nim or perhaps something more C-ish like Zig, but those projects don't have the same buzz so here we are. There's probably more young devs who are into Rust than C nowadays.

I am not holding out much hope for Mojo because it feels deeply embedded in the AI/LLM hype space instead of being presented to Python devs outside of that niche as a useful language extension in its own right.

I wonder if this can be predicted by a heat map of car crashes in your area. This is based on my private hunch that car crashes are a predictor of bike crashes. After all, if a car can crash into another car, or a stationary object such as a tree or a building, then it can crash into another bike. And the causes may be similar: Speed and inattention.

On such a map for my locale, the most crash-prone roads are exactly the ones that I instinctively avoid.

The consumer landscape has gotten so hostile. Once upon a time you could use price as a proxy for evaluating quality. More expensive versions of a product were generally better.

Nowadays it's all smoke and mirrors; marketing, branding and lies. In general I find even the more expensive versions of consumer products are still garbage quality which end up in a landfill all to quickly. It's hard to buy something good even if you're willing to spend the money. Our current capitalism doesn't care about providing value for the money, no it's all about how much money to can squeeze out of people and how low you can make your production costs.
