Credits of a dollar value, not service, I believe.

Like "for a dinner" can expire, because the COGS associated with that can go up, and a business is being cost $100 for a dinner that they may have only been paid $50 for previously.

But if for a dollar amount, then it cannot be expired.

Ashley Home Furnishings, since this reminds me, are all sorts of out of compliance here. We were given gift cards by them for issues with purchases. Fine. Then when we bought our home, several family went there, and purchased gift cards with cash. We tried to use them and were told they could not be used on anything that was discounted or on sale, despite them having received cash for the card. (Side note, guess how easy it is to find anything there that is not ostensibly discounted?)

I have this theory that a big driver of the lack of housing, and the resulting high prices, is due to the lower rates of marriage. More single occupancy homes means more homes are required. This goes hand in hand with a declining birth rate. So this breakdown in the family structure could be at least partially responsible for both the rise and collapse of housing prices. That’s kind of interesting.

This was a (minor?) plot point in Crichton's "Sphere".

Paraphrasing: if a smart bacterium steps on the battery of one of our space probes and gets destroyed by the heat, the smart bacteria community may think the aliens (we, humans) sent it to them for unfathomable reasons, perhaps to teach them a lesson, but we didn't think of them at all.

We’ve spent years building systems that understand... But now, we’re entering a phase where AI can actually act. Not through APIs or complex integrations, but right from your machine, with simple tools and natural language.

In this post, I explore a powerful shift made possible by MCP servers:

Because it's possible to protect yourself against that with anonymity. That goes out the window the moment tokens tied to your real identity get involved.

Not to mention that it's likely they wouldn't be able to spy on absolutely everything you do, just parts of it. The tokens would be an obvious point of interest.

On top of that, it's probably a lot easier for the government to justify this kind of spying. They could probably twist information about token use as being some kind of "metadata", therefore "okay to spy on".

That was a lovely vignette, thanks. Much earlier in my career I had exactly the sense suggested that “something’s off” about the Schwartzian, even though it became a useful and idiomatic tool at the time. I only really understood the disquiet much later, when working with columnar data, and realising the positive qualities of declaring structs-of-arrays rather than arrays-of-structs, with subsequently excellent mechanical sympathy, and so on from there.

Hi HN,

I recently launched https://mcp-debug.com, a lightweight web tool for formatting, validating, and exploring JSON-RPC messages — especially those using MCP (Model Context Protocol) patterns.

Why I built this I was working with tools that use JSON-RPC (like OpenAI's MCP for tool calls), and debugging them became frustrating. There were no lightweight, opinionated, client-side-only tools to:

Validate the message structure

Spot schema mismatches

Format huge .jsonl log files

Visually explore nested params or error responses

Every time, I’d bounce between generic JSON formatters, my IDE, and a mental checklist of MCP rules (like jsonrpc: "2.0", method, params, id).

So I built MCP Debug to centralize all that.

Features Paste any MCP/JSON-RPC message and see validation in real time

Syntax-highlighted JSON viewer with collapsible tree

Compare expected schema vs actual params

Upload .jsonl logs and explore them in a clean table

Fully client-side (React + Tailwind) – no data ever leaves your browser

Fast UX, minimal bloat, dark mode by default

Who this is for Devs building with JSON-RPC APIs

Anyone debugging LLM tool calls or agent logs

Anyone tired of bloated formatters and 5-tab workflows

What’s next Save/share logs

I’d love feedback, ideas, or just to hear if this helps you.

I feel guilty because the house I grew up in and the house I currently live in were both formerly farmland (cherry orchards and grain fields respectively). I wonder why are we paving over prime farmland while simultaneously dedicating 5% of all US territory to growing field corn. Sorghum, field corn, and cotton are grown around here, depending on market conditions.

> So far, AI has had the opposite effect on my site. I've now been featured on both Hackaday and Adafruit's blog. Both features were clearly AI-generated. Both posts coincided with an influx of emails from folks interested in my work.

This may be missing some context, but it seems as though you're saying that you made something with AI and it led to traction. That's great! Seems off the point that blocking LLM service will lead to less exposure over time though.

> Perplexity is good at citing things when it decides to cite things and when you tell it to cite things.

Maybe I'm just lucky, but a quick skim of my Perplexity history yielded only 2 instances of no citations, and they were for general coding queries. I've never had to ask it to cite anything, as that's built into the default prompt.

> lose those aforementioned email conversations.

I think those will remain a possibility as long as LLM users, or services, ensure citations are included in output.

It wasn’t like they were sitting on a pile of nukes. They had to make the maximum concrete, visceral impact with the couple they had such that there would be minimal second-guessing on the part of Japan.

You are suggesting that they should have selected a target that was virtually guaranteed to have less impact and leverage with a very scarce resource. They couldn’t afford to take that risk with American lives.

Oh, so as part of your concern that it shouldn't be "improper" to think about, discuss, or enjoy Loeb's ideas, you suggest that the author of that video should "feel bad" about criticizing it? Nice, that's really cool of you. Loeb is allowed to enjoy the ideas of it being an alien spaceship about to Dark Forest us, but no one is allowed to push back against it.

There's no such thing as a "dispute" about what ideas are proper to discuss and enjoy. There might be a dispute concerning leveraging Harvard credentials and a Harvard domain name to distribute playtime fun math with no basis in observational reality, because the first thing every article written about this paper will now say is "Harvard researcher" [1]. That's academic misconduct. Go start a substack; I'm sure Joe Rogan would love to have you on a guest, and you might even get Netflix to give you a show [2]. Three beautiful avenues available to even the most crackpot individuals; way more profitable, too.

Loeb states "there has been to-date absolutely no sign from spectroscopic analysis of cometary activity on 3I/ATLAS." A week later: Look at that, its ejecting water and is almost definitely a comet [3].

If you walk into a doctor's appointment with a tummy ache, and the doctor says "well, its probably just food poisoning, but wouldn't it be a fun exercise to pretend its stomach cancer?"; be serious, do you believe that is an appropriate way for a doctor to behave? Why would anyone think that any professional in any field, most of all at a respected institution like Harvard, should be held to such low standards of behavior? Discussion and postulation is awesome and fine, but if you can't consider the implications of your authority and the choice of medium, you won't have either for very long.

On the class topic, I suspect that attendance was more impactful for students pre-internet as the alternative was to wade through the library piecing together material.

With lecture notes/slides available online, well prepared books and study forums readily available - in-person attendance can feel archaic.

We may be experiencing a similar dynamic in education with AI. In a world where we can create individualized curriculum’s for each student encompassing the entire tree of knowledge - Perhaps it’s time to rethink how we educate students rather than push them into lecture halls designed for the Middle Ages.

1. Write exhaustive automatic tests against the API you are responsible for.

2. Don't write tests for anything else.

If you are responsible for implementing a server/service, the API is the protocol for the server/service. If you are responsible for implementing a module/library, the API is the public interface to your module/library.

The tests are basically a specification for how any implementation of the API needs to behave. So you can give the tests to another developer, who has never seen your implementation, and they should be able to re-implement everything based on your tests.

"One of the things that stood out to me right away was how dreadful UI looked. Not only it felt uninviting, but it almost felt “gatekeepy” - if you don’t know how to use it in this configuration, then might as well forget about it."

I'm puzzled how we get from unintuitive interface to "gatekeepy" (which I'm assuming implies a deliberate attempt to make the set of users small). Things can be difficult to use without anyone setting out to exclude new users, some things _are_ difficult to use, and other things are written by people who haven't been paid to make them address the needs of a wider range of users than they want to.

This is wrong in so many ways. Just using the buy or rent calculator demonstrate this. You are essentially repeating realtor talking points ("Renting is throwing money out of the window"). You need to use real numbers and compare them to the rent equivalent.

* Down payment: not a real cost, that money is yours in the form of equity

The opportunity cost of the downpayment is the issue. The equity you gain from downpayment is nowhere close to the opportunity cost of investing it in the stock market.

Owning MIGHT have been an OK investment for most Americans 20 years ago. that is absolutely not the case today anymore.

Ah yes, so you timed buying your house perfectly due to the one time increase during covid ("7 years ago"), and you think this generalizes to anyone buying today.

This is the same story as me anecdotally saying that I bought Nvidia 6 years ago therefore Stocks are always absolutely better.

So let me ask you? Based on your logic there is no price at which buying makes no more sense? What is the cutoff for you? What if you could rent a 4M$ house for 4k$/Month? Is it still a great deal? What if that house only goes up 2% a year?

Those are the only things that matter. The hard numbers! And right now they do absolutely not make sense.

> I was pointing out that you don’t know what you’re talking about.

This discussion is pretty much done, but I just wanted to note that I’m not the original poster you were replying to.

> You cannot conclude that a truck never goes off-road by observing them on city streets. That was your claim, and I explained why it didn’t make sense.

No, the claim is that the majority of them are not going off road, not any particular vehicle (yours included).

I enjoy cars, and driving a large pickup is fun. I also happen to think they are not appropriate vehicles for the majority of people, should not be a default option, take up way too much space, and make city roads significantly less safe. This is not an emotional response, just an opinion. If your use of a pickup makes sense I don’t think anyone has a problem with that.

And yes, I also agree that 200hp+ ICE cars are wasteful, and even if they are an EV, most people should not be driving something that powerful as it also has an impact on road safety. Similar thing: you enjoy cars, drive well, and own an SRT? Great, have fun! Should the average driver have one? Hell no.

You know who's won every single selection in modern history? "None of the above." Even in the 2020 election where millions of mystery people suddenly appeared, only 155 million people voted with a voting age population of some 256 million. Some of those 101 million (the delta between voters and 'abstainers') couldn't vote, but most could.

And that, to me, indicates rather widespread rationality. Because elections are a facade. Do you want to vote for somebody who struggles to complete a single coherent sentence and has a grand vision of 'I'm quite fond of power', or for a narcissistic entertainer? Either of which who will agree on most things that people themselves disagree with, like injecting ourselves into endless conflicts around the world because the MIC needs that dough. No thanks. I'm quite happy with my 'none of the above.'

So the conclusion I'd draw is that there's two rather radical sides constantly flinging poo at each other and pretending this moment is the most important moment ever, always, while everybody else looks on from behind the glass amused at a bunch of monkeys covered in poo which, come to think of it, also works as a fine metaphor for internet discussions.

passenger seats already have an occupancy sensor that you could probably hook into to make a passenger seat bypass somehow.

don't get me wrong, this would probably be horribly unpopular, but otoh deaths from cars are up ~50% in the last decade, bringing us back to ~1985 in car safety. Something fairly drastic is needed

It is wrong to compare number of characters in English to number of words in Chinese. The proper comparison would be words in English to words in Chinese. By 4th grade I knew enough English to proofread ycombinator posts. Of course, that is a low bar...

And I think you're off by an order of magnitude about vocabulary size. Chinese vocabulary size around 6th grade is more like 2K - 4k words tops, not 20K. See

The today does matter but just did the math on that and your teacher was whack.

The gap is so big I’m going to be imprecise and won’t matter.

A Roth allows 7k a year I believe. So 4 years of school, 28k total.

Let’s be generous and say you start with 30k at age 18. At 65 you’ll have 700k.

I started at 26, my salary has been increasing at 6k a year average. I don’t max it out, but hover around 10-15%, I get a 100% match on up to 7% of my salary. I’m 10x ahead of the 18yo on the same projection and 5x ahead 10 years earlier.

> Another related rule: never commit code to the main branch that hasn't been read by at least two humans.

Passive code reviews ("read by at least two humans") are fraught with error. IMHO, a better mantra is:

Never allow a merge to the main branch that does not have some amount of documented test coverage, be it unit, functional, and/or integration specs.

>Are you sure that Bitcoin payments work much better because the amount of payments has dissipated?

I don't know. On the base layer, payments are all just transactions on the Blockchain, like any other. So it's not easy to see whether a transaction is a payment or an "investor" speculating, or something else. Then there's also other layers, like Lightning.

My guess is the relative percentage of retail Bitcoin payments, compared to speculative transactions, is now lower than 2017, when Steam accepted Bitcoin. I don't know if absolute amount of payments has reduced. Maybe?

You could look at historical charts of average Bitcoin fees[0], which gives you an idea when retail Bitcoin payments are practical, and when the fees are too damn high. Fees often got above $4, sometimes much higher, in 2024 for example, which would unacceptable for something like buying a game from Steam. Though, still, that doesn't show what impact Lighting is having on retail payments.

No he has not. He was talking about an AI model that was shown off for crudely animating 3D people in 2016, in a way that he found creepy. If you watch the actual video, you can see the examples that likely set him off here[0].

Maybe that's not something that's terribly fulfilling to you, but if one takes joy in the process itself then the act of saving a dollar on icecream can bring both more hedonic and eudaimonic pleasure than having the icecream would have, and pay off materially. Especially in the very-long term.

In your head it's Ebeneezer Scrooge, but it can just as well look like ...err, Scrooge McDuck maybe? I struggle to really find a good example for what I'm talking about. But if you make a challenge to yourself, being frugal can be very fun and fulfilling, even moment-to-moment.

Frigate has been ok for me when paired with a gpu or tpu for to speed up the object recognition features. It's the closest I've found to the usual IP camera cloud sold by the IP camera manufacturers.

That said, it's installation method uses containers, which I could do without. Configuring it can feel a bit fiddly depending on the hardware you have, but that's likely to be the case with most NVR systems that support a wide variety of setups.
by hintklb | 2025-08-05 04:47:51+00:00
That was the case initially.

Now the prices have skyrocketed due to offer and demand, and frankly because of the narrative that "Buying is always good", which ironically makes it a subpar investment.

Real estate is now a subpar investment. Especially today, and even with those advantages. It is also not diversified at all, absolutely not liquid and does not return even close to the SP500 (Even if you take the leverage into account, and leverages go both ways by the way...).

Hm, it’s still a tricky question. Do web admins have a right to block agentic AI? Of course they do. They have a right to block whoever they want. Distinguishing between scraper and agent is important, yes, but agents can still produce a lot more traffic than the average human, and it’s not like the agents are optimizing their access patterns.

>They had to make the maximum concrete, visceral impact with the couple they had such that there would be minimal second-guessing on the part of Japan.

And yet they didn't decide to bomb Tokyo or Kyoto. There was clearly a calculus done in selecting the targets to find the right balance of all the various factors involved. I don't see the problem in questioning whether they came to the right decision. Too often the target selection decision is assumed to be right and the only decision that is questioned is the yes or no of actually going through with the bombing.

Is this a condo with an outrageous HOA that you are not including? Many such cases that explain why condos are valued so much lower.

In SF I have been renting a 1.6M$ townhouse for 4k$/month, and that is very typical of what you can find in SF and in SV.

I think its totally fair to be aggressive in pushing back against abstracts like "and hypothesize that this object could be technological, and possibly hostile as would be expected from the ’Dark Forest’ resolution to the ’Fermi Paradox’".

There is zero testing of either the hypothesis that it is technological or that it is hostile. At best, the methodology he employs in the paper could be argued to test the hypothesis that its path through our solar system is synthetic and intentional; but that's it, and that's also not remotely close to what he said.

Sadly, right now, bitwarden is the only provider that will dump your passkeys into a JSON. No one else offers it, and there is no functionality from any provider to import and adopt the JSON that bitwarden exports.

Passwords have their faults, but they do have a zero-technology backup option that your heirs can execute. (A printed dump of the password vault in a locked fire safe.)
