Just wanted to say thanks for such a good write-up and the great work on Otter over the years. We've used Ristretto since the beginning of building SpiceDB and have been watching a lot of the progress in this space over time. We've carved out an interface for our cache usage a while back so that we could experiment with Theine, but it just hasn't been a priority. Some of these new features are exciting enough that I could justify an evaluation for Otter v2.

Another major for on-heap caches that wasn't mentioned their portability: for us that matters because they can compile to WebAssembly.

> The camp was established by the 10th Legion, who was stationed in the area between AD 172 and 180

This is interesting wording. I have a strong urge toward saying either of two other options:

- "The camp was established by the 10th Legion, who were stationed in the area between..." [The Legion is a collection of people]

- "The camp was established by the 10th Legion, which was stationed in the area between..." [The Legion is not a person]

I have difficulty interpreting the Legion as a single person, though. Does the wording in the article work for other people?

---

As to the item itself, I find it a little odd to call it a "purse", since it's reconstructed as a solid metal object. That sounds inconvenient and uncomfortable at best.

> the public discourse either lacks motivation, understanding or incentive to take a proper look.

Indeed. Almost always in these discussions people have already made up their minds about the state of the economy and will just cherry-pick whatever metric best justifies their case (typically that the economy sucks).

There's never been a time in my life where people weren't complaining about how the economy is terrible and how that's clearly obvious if you just look at the real numbers.

> make sure everyone is well aware about how their attention is the new currency in the modern age, and spend it wisely, being aware about the addictive and self-reinforcing nature of some systems.

i.e. delete your facebook, your tiktok, your youtube and return to calling people on your flip phone and writing letters (or at least emails). I say this without irony (The Sonim XP3+ is a decent device). all the social networking on smart phones has not been a net positive in most people's lives, I don't really know why we sleep walked into it. I'm open to ideas how to make living "IRL" more palatable than cyberspace. It's like telling people to stop smoking cigarettes. I guess we just have to reach a critical mass of people who can do without it and lobby public spaces to ban it. Concert venues and schools are already playing with it by forcing everyone to put their phones in those faraday baggies so maybe it's not outlandish.

The obsession with trying to explain a monad ultimately stems from conflicting explanations and the inability to differentiate between a mathematical monad and monads implemented in software.

Monads in software are just a standard API for any given type. That’s it. Theres no magic here. Just implement the standard and you have a monad.

It grinds my gears seeing monad tutorial after tutorial using the wrong metaphors or misleading explanations

Can confirm, universities aren't giving money to researchers- they're actually taking a cut of the grants that actually fund research. They don't even pay salaries, that's only in exchange for teaching hours.

Thankfully, since grants started putting caps on how much the university is allowed to take I haven't seen a 50% overhead cut in a long time. It's still a pretty significant chunk though.

I recently just got my RMA fulfilled for a Pixel 5 that developed a spicy pillow after 5 years, but I've already sworn off Pixel devices from here on out after this and a total lemon of a Pixel 6 I had bought my wife for her birthday.

In general, the whole planned obsolescence business model of smart phones has really soured my opinions of this technology that is now central to our lives.

Hey HN,

I’m building CeresAI (https://ceresai.xyz), a web-based platform that turns your own WhatsApp/Instagram chat history into a personalized AI companion. We’re just about to open our beta and would love some feedback on:

* Onboarding & trust: How have you guided first-time users to connect their chat history without feeling uneasy? * Early traction: Which channels (Reddit, Hacker News, Twitter, etc.) worked best for you to get those first 100–500 users? * Retention hooks: What onboarding features or UX patterns kept people coming back to a new AI service?

Happy to share more details or prototypes if it helps. Thanks in advance for any pointers!

Just like many others, I also have this problem: it’s getting harder and harder to find the articles I’ve read later. There’s so much great content I come across every day that, in my experience, it’s rather difficult, if not impossible, to find it again by searching Google. So I started building a personal solution to keep the stuff I read searchable.

There are existing tools that try to solve this, but I have some unique requirements that pushed me to create my own. Things like Telegram integration, weekly summaries, and indexing YouTube content. More importantly, I felt the pain enough that I was motivated to work on it as a side project.

A good example is the frustration and disappointment I had with Pocket: the search functionality was terrible, and each update seemed to make the product less usable.

I’ve now got a working prototype, and I’m putting on the final touches. Let me know if you have any thoughts, or email me if you’d like to try it out.

This is all going to be solved by better models. Building agents is building for a world that doesn't quite exist yet, but probably will in a year or two. Building some big heuristic engine that strings together LLM calls (which is what this blog advocates for) is essentially a bet against progress in ai. I'm not taking that bet, and neither are any of the major players.

Curious if the content on those sites might have high value to Google? Such as if they have data that is new or unavailable elsewhere, or if they're just standard sites, and you've just been unlucky?

I have had odd bot behavior from some major crawlers, but never from Google. I wonder if there is a correlation to usefulness of content, or if certain sites get stuck in a software bug (or some other strange behavior).

Let's not engage in quakery and resort to knowledge instead.

Oral and transdermal (topical) application of Vitamin C (and other molecules in general) follow completely different routes with different absorption rates and accompanying nuances.

Oral intake. Absorption rate is dosage dependent:

– At moderate doses (≤ 250 mg/day): 70–90 per cent of ascorbate is absorbed into the bloodstream. Bloodstream means just that – Vitamin C will be distributed throughout the entire body, which includes tissues, internal organs and skin. Active absorption takes place in the small intestine predominantly by SVCT1 and SVCT2 sodium-ascorbate co-transporters. – At high doses (≥ 1g a day): passive diffusion takes over and also takes place in the small intestine although now via GLUT transporters that become saturated and absorption efficiency drops to 50 per cent or lower.

The half-life of Vitamin C taken orally is approximately four hours anyway, after which any excess of it still circulating will be rapidly excreted via the renal route (kidneys). Studies report that significantly less than 0.1 per cent makes into the epidermal (skin) layer.

Transdermal (topical) application. Depends on the concentration and several factors, but a 20% concentration serum (not a cream) can achieve a > 80% absorption rate through the skin into receptor fluid after 24 hours. Half-life of Vitamin C applied topically is approximately 4 days.

Recap: less than < 0.1 % / 4 hours half-life for the oral route vs more than 80 % / 4 days half-life for the transdermal route.

Why do you believe those aren't good examples of cutting edge science funding? I get the stereotype that government organizations of all types are just stodgy bureaucrats stuck a few decades in the past, but the reality at least in the US in the year 2025 is that truly cutting edge science is not obviously being funded at any significant scale anywhere but government.

The world of privately funded research organizations like Bell Labs is long gone, with companies being barely able to look past the next quarter never mind being willing to invest in long term research that may not pay off for a few decades, if it pays off at all. And by definition most cutting edge science has that kind of financial time horizon. If there was an obvious, short term path to directly benefiting those conducting it, it's probably not very cutting edge at all and closer to engineering than actual scientific research. Not that there is anything wrong with that, we need engineering investment too. But it's not a replacement for science research.

I think a lot of people who scoff at the idea of government being on the cutting edge of science research don't understand how that research is being conducted. Sure, some of it is done by actual government employees, but especially for organizations like the NSF, the bulk of the research is being done by organizations and individuals outside of government who are simply given a check to look into things that might not immediately pay off or which have major societal benefit but no real path to commercial payoff.

Yea that's practically nothing, even accounting for your population. It's $2/person compared to NASA's pre-cut budget of about $80/person/year. Where are all these other countries that might pick up the slack? Seems nobody else in the world wants to pay for science. They might complain about American science funding cuts but are happy to keep their already tiny science budgets tiny.

Norway's overall science budget is $1 billion per year, or $200/person/year. US's was $200 billion/year or $600/person/year. So Norway isn't really pulling its weight.

That Friend speaks my mind. :)

In seriousness, I agree — it's always odd to see Quakerism discussed in other contexts, as well as running into other Quakers in other contexts outside of things like /r/quakerism or such. I do wish it were a more widespread practice, as I feel like it's such a good anodyne to the modern "I got mine, forget you" approach endorsed by so many megachurches.

Hm, without more details on the use case and assuming no "round trip to a network" means everything is running on a single host I see a couple of options:

1) Shared memory - use a cache/key-value lib which allows you to swap the backend to some shmem implementation

2) File-system based - managing concurrent writes is the challenge here, maybe best to use something battle tested (sqlite was mentioned in a sibling)

3) Local sockets - not strictly "no network", but at least no inter-node communication. Start valkey/redis and talk to it via local socket?

Would be interested in the actual use case though, if the monolith is written in anything even slightly modern the language/runtime should give you primitives to parallelize over cores without worrying about something like this at all... And when it comes to horizontal scaling with multiple nodes there is no avoiding networking anyway.

Somewhat related, on YouTube, there's a channel filled with fake police bodycam videos. The most-viewed of these are racially inflammatory, e.g.: https://www.youtube.com/watch?v=5AkXOkXNd8w

The description of the channel on YouTube claims: "In our channel, we bring you real, unfiltered bodycam footage, offering insight into real-world situations." But then if you go to their site, https://bodycamdeclassified.com/, which is focused on threatening people who steal their IP, they say: "While actual government-produced bodycam footage may have different copyright considerations and may be subject to broader fair use provisions in some contexts, our content is NOT actual bodycam footage. Our videos represent original creative works that we script, film, edit, and produce ourselves." Pretty gross.

> but I don’t know that these are the best exemplars of cutting edge science being shut down that will lead to America’s downfall from its scientific perch

Most of these agencies do some foundational science but maybe more importantly they collect lots of boring data. Boring data they give out to researchers for free. They also hand out grants which might not be lottery tickets but they pay for boring stuff.

The current administration believes that if you stop measuring any problem it ceases to be a problem. No one can push back on their flood of bullshit about everything if there's no data to point to. Authoritarians despise objective reality and empirical measurement and will always strive to make it easier to push their bullshit narratives.

Off the cuff the closest example to mind is the Paedogeddon!! special episode of the Brass Eye series created by Chris Morris.

Admittedly that didn't satirize CSAM material, rather it cut hard into the reflexive reaction people have at the very thought of CSAM and peodophiles.

Moreover, that took a human to thread that needle, it'll be a while before AI generation can pass through that strange valley.

> This is exactly the scenario I was describing - this is not a sign of a cooling economy with rising unemployment or underemployment

It could be. What if B is outcompeting because they have offshored labor, or using new technology that reduces demands for labor. Not that those things are necessarily bad, but just because the total productivity is increasing doesn't necessarily mean everyone is better off.

My point is that the situation described can happen without a change to the average income, and average income isn't a good metric for watching changes in wealth inequality.

> but it's very much not what unemployment is meant to be tracking.

I never said it was.

> Tons of such metrics are frequently discussed. Things like ratio of CEO to employee pay and income percentages are given all the time

IME, such things are talked about much less than unemployment, especially in relation to politics and policy.

And I think part of the reason for that is because it is easy to understand, and it is easier to control with policy than other metrics, since the government can just create new jobs and provide incentives to create jobs, even if those jobs are lower paid than the jobs that were lost.

Maybe! But it seems like it's points well taken today. The important thing I think to keep in mind is that LLM calls themselves, anything that's happening inside the LLM, is stochastic. Even with drastically better models, I still can't tell myself a story that I can rely on specific outputs from an LLM call. Their outputs today are strong enough for a variety of tasks, when LLMs are part of the fabric of a program's logic --- in agent systems --- you need an expert human involved to notice when things go off the rails.

> Plenty of big unions out there, and plenty of places where growing base actually strengthens the union, since they can afford to do more for members in the event of a strike.

Union membership is strictly bound by the number of jobs.

Unions, especially in the private sector, cannot directly control the number of jobs. At best they can negotiate the percentage of union jobs at a facility or site.

An influx of non-union labor into an industry where unions already don't represent much of the labor force weakens a union's bargaining position.

The unions could try to attract those non-union workers to the union by explaining the protections that come from labor organizing, but if people are desperate enough for work, they likely won't want to rock the boat by joining a union.

Adding to that, in the US at least, the labor protections functions of the Federal government are being systematically undermined.

It probably also belonged to a certain period of time and a certain generation. The peak of couchsurfing coincided with millennials coming of age, and provided something that appealed to them at the time. Namely, cheap travel and interesting, random experiences to brag about.

That demographic is a lot older now, and the younger generation has other interests and expectations which couchsurfing likely does not appeal to.

There are six kinds of unemployment stats the US tracks (below). Nothing sounds specific to underemployment by skills specifically (maybe u-6?). That would probably come from other metrics, like quintile income distributions shifting downwards?

You didn't ask, but just in case (from an internet search):

U-1: Long-term unemployed

* Definition: People unemployed 15 weeks or longer, as a percentage of the civilian labor force.

* Purpose: Measures persistent unemployment.

U-2: Job losers and temporary workers

* Definition: People who lost jobs or completed temporary jobs, as a percentage of the labor force.

* Purpose: Captures recent layoffs and temp contract ends.

U-3: Official unemployment rate (headline rate)

* Definition: Total unemployed as a percentage of the civilian labor force.

* Purpose: This is the standard "unemployment rate" reported in news and economic discussions.

* Limitations: Doesn’t count discouraged workers or part-time workers wanting full-time jobs.

U-4: Unemployed + Discouraged workers

* Definition: U-3 plus discouraged workers (those who want a job but stopped looking because they believe no jobs are available).

* Purpose: Adds a layer of marginal attachment to the labor force.

U-5: Unemployed + All marginally attached workers

* Definition: U-4 plus all others marginally attached to the labor force, not just discouraged workers.

* Marginally attached workers: People not currently working or looking for work but who want a job and have looked in the past 12 months (but not the past 4 weeks).

U-6: Broadest measure

* Definition: U-5 plus part-time workers who want full-time jobs (i.e., involuntary part-time workers).

* Purpose: The most comprehensive measure of labor underutilization, including: Discouraged workers, Marginally attached workers, and Underemployed part-timers

The parallel isn’t perfect.

But the deep irrationality driving artificial opportunistic ideological divides (this time less raw white supremacy, but still a lot of xenophobia, party loyalty propaganda, cult of personality, and fear and backlash with respect to minorities), drives sub-cultures like lemmings, off the cliff of reality. Taking the rest of us with them.

I think the cynical student paying tuition in America would ask what the money is actually paying for and why it can’t cover the full cost of programs and research given that it’s so high.

Let’s say you go to Ohio State. The out of state (unsubsidized) tuition comes out to about $37,000 for full time tuition. That’s around 108 hours of instruction per year by my estimation.

Students are paying $342 per lecture hour, which means each professor is bringing in between $3000-30,000 per hour.

Sure they have to grade papers but…come on, right?

How is this not wildly profitable?

This does not include room and board, which has to be even more wildly profitable. Imagine being able to charge $1200 a month for a shared room with no kitchen or private bathroom with some cafeteria slop as included food.

I finished a formal university degree recently and probably only 1/4 of my professors were actually actively decent and all the lessons were heavily recycled copy paste jobs that get passed around the department.

Online school makes this an even worse value since the professor just grades electronic work and spends one hour a week on chat hours, with the rest of the lectures being pre-recorded or pre-written.

To be clear, I personally believe the government of wealthy nations should fully cover the cost of higher education to anyone who wants it because it’s a no-brainer obvious investment that pay off in positive societal ROI. My commentary simply concerns the status quo where costs are high despite subsidy and endowments still existing.
