I think people are maybe missing a key development with stable coins recently. They can be used by AI agents to pay for access to protected API endpoints or websites. The http 402 status endpoint is finally being utilised, years after it's creation. Ycombinator has a lot of AI based startups and they are given unlimited tokens.

All crypto/browser automation/bot detection companies are jumping on the bandwagon:

https://docs.cdp.coinbase.com/x402/core-concepts/http-402

https://docs.browserbase.com/integrations/x402/introduction

https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/...

https://docs.datadome.co/docs/monetize-policy

In a world without search engines, LLM chat bots will need to be held to account for the server resources they're using. Seems like a lot of companies are betting on them paying for access or acting as AI shopping agents.

Can only speculate out of thin air - B200 and Ryzen 9950x made on the same process and have 11x difference in die size. 11 Ryzens would cost $6K, and with 200Gb RAM - $8K. Googling brings that the B200 cost or production is $6400. That matches the numbers from the Ryzen based estimate above (Ryzen numbers is retail, yet it has higher yield, so balance). So, i'd guess that given Google scale a TPU similar to B200 should be $6K-$10K.

In my lifetime, I had my card details stolen once (in Washington DC). It was an American Express. They caught it immediately and shipped me a new card before I even noticed.

It was basically “we caught some shady shit, here is your new card number, which will be delivered today”. It is one of the reasons I like Amex. They are johnny-on-the-spot when they get a sniff of fraud.

As far as I can tell from the reporting:

* They exchanged various emails between 2012 and 2014 about Elon visiting the island

* They made plans for Elon to visit the island

* We don't know if Elon actually followed through on those plans and he denies it

I think it's premature to say he didn't go, and the latest batches of emails directly contradict the claim he wasn't ever invited.

While it is the original title, it's clickbait.

No platform has ever "killed" off widgets, and users love them as long as there's a good variety of high quality ones available.

The first thing I always do with a new phone is make sure I have my preferred widgets for weather, email, maps, calendar, and to-do. As long as they stay in the periphery providing ambient information and the occasional interaction, being without them is almost unthinkable.

Maybe the only slight improvement in decades has been the smartwatch.

Coding is not at all like working a lump of clay unless you’re still writing assembly.

You’re taking a bunch of pre-built abstractions written by other people on top of what the computer is actually doing and plugging them together like LEGOs. The artificial syntax that you use to move the bricks around is the thing you call coding.

The human element of discovery is still there if a robot stacks the bricks based on a different set of syntax (Natural Language), nothing about that precludes authenticity or the human element of creation.

> This is the part that might not be the same in all US jurisdictions (though it appears it is the same in some, someone posted upthread about Iowa having a system like this).

As I pointed out in a reply to that comment, that's a popular misconception – legally, Iowa uses essentially the same land title system as every other US state; the main difference is instead of private title insurance, there is a state government monopoly on title insurance. But Iowans use the phrase "title insurance" to mean "private title insurance", making many of them wrongly think their state doesn't have title insurance at all.

Several US states previously enacted Torrens title, but largely unsuccessfully – few titles were ever converted to Torrens, and in almost all of them Torrens title is either repealed or effectively moribund.

The only place under US jurisdiction where Torrens title is fully mainstream, is Guam. Guam adopted it in the early 20th century, around the same time as the US territories of Hawaii and the Philippines did. It survived in the Philippines, but the Philippines became an independent country. In Hawaii, it was successful in a few parts of the state (in particular Lānaʻi), but otherwise largely not.

Show HN: Augmenting developer docs into high-level interactive mental models
by b_mutea | 2026-02-04 07:30:47+00:00
I’ve been experimenting with a tool that turns developer documentation into interactive, high-level maps of a product’s architecture. The goal is to help engineers, technical writers, and curious readers quickly build a system-level understanding before diving into details.

Docs are usually great at explaining individual features, but it’s often hard to see how components relate and flow. These maps extract the structure and relationships from the documentation, making it easier to understand dependencies, workflows, and overall architecture.

I’m publishing this incrementally. The first public iteration is a mapping of LangChain’s documentation: https://docmaps-web.vercel.app/maps/langchain-documentation-...

I’d love to hear feedback, ideas, or use cases where something like this would be helpful.

I dont think LLMs really took away much thinking, for me they replaced searching stackexchange to find incantations. Now I can get them instantly and customized to my situation. I miss thinking hard too, but I dont blame that on AI, its more that as a dev you are paid to think the absolute minimal amount needed to solve an issue or implement a feature. I dont regret leaving academia, but being paid to think I will always miss.

He uses the keys of his non-exit relay to directly connect from his workstation to an exit relay pretending to be the relay on his VPS. But yeah he could just use the VPS for wireguard which would be way easier.

I'm in Europe so I don't get less than 20Mbit/s on any circuit but I asume he could have got the same speed by just selecting a few local, fast nodes as bridge.

My favorite nonsensical category 4 classification is anything with achiote in it. It's not part of a traditional European diet, and it's often used to add color so it makes the list, despite saffron having a similar role in European food and booth being a traditional and completely unprocessed ingredient.

Speaking of Mesoamerican ingredients, nixtamal is pretty heavily processed, and is a staple in many areas, but it's much healthier than unprocessed corn which can cause pellagra when used as a staple food.

Exactly, and that's why I find AI coding solving this well, because I find it tedious to put the bricks together for the umpteenth time when I can just have an AI do it (which I will of course verify the code when it's done, not advocating for vibe coding here).

This actually leaves me with a lot more time to think, about what I want the UI to look like, how I'll market my software, and so on.

Some guys made this website with instructions of how to setup/play games: https://everdeck-library.vercel.app/

I feel like they did a great job but didn't get enough visibility. It hasn't been updated in a while and has a limited selection of games, but it's a great attempt to centralize game mappings. I hope comunity embraces this or similar tools, as the huge BGG lists aren't really built for this.

They describe their website as:
The Everdeck Library was developed as an alternative archiving option for the various games playable by the Everdeck. Most of the Everdeck’s game lists are available on online forums such as BGG and Reddit. The Everdeck Library takes the format of those game lists and expands upon them by providing in-depth information and interactivity from being able to filter out certain games to knowing how the Everdeck maps to the game’s cards and rules. Sifting through the Everdeck’s 120 cards for the game you’re playing is quite involved and forgetting a card or not knowing what a card does can heavily hinder gameplay experience. Tabletop games are a way to gather people around and the last thing you want is fumbling around with rules and setup.

> Dragon is using CotS, non rad-hardened CPUs. And it's rated to carry humans to space.

Those are not independent facts. They put the hardware inside, behind the radiation shielding they use to keep the astronauts safe. It's why regular old IBM laptops work on the Space Station too. That kind of shielding is going to blow your mass budget if you use it on these satellites.

SpaceX, which prefers COTS components when it can use them, still went with AMD Versal chips for Starlink. Because that kind of high performance, small process node hardware doesn't last long in space otherwise (phone SoC-based cubesats in LEO never lasted more than a year, and often only a month or so).

Juicy paper, not to mention the declassification. It really reminds me of asyncmachine.dev which has actors, relations, transitions, and embraces non-determinism.

Here is the professional English translation of your analysis, optimized for a technical audience or a blog post:

Why I Believe MySQL is More Suited than PostgreSQL for DuckDB Integration
Currently, there are three mainstream solutions in the ecosystem: pg_duckdb, pg_mooncake, and pg_lake. However, they face several critical hurdles. First, PostgreSQL's logical replication is not mature enough—falling far behind the robustness of its physical replication—making it difficult to reliably connect a PG primary node to a DuckDB read-only replica via logical streams.

Furthermore, PostgreSQL lacks a truly mature pluggable storage engine architecture. While it provides the Table Access Method as an interface, it does not offer standardized support for primary-replica replication or Crash Recovery at the interface level. This makes it challenging to guarantee data consistency in many production scenarios.

MySQL, however, solves these issues elegantly:

Native Pluggable Architecture: MySQL was born with a pluggable storage engine design. Historically, MySQL pivoted from MyISAM to InnoDB as the default engine specifically to leverage InnoDB's row-level MVCC. While previous columnar attempts like InfoBright existed, they didn't reach mass adoption. Adding DuckDB as a native columnar engine in MySQL is a natural progression. It eliminates the need for "workaround" architectures seen in PostgreSQL, where data must first be written to a row-store before being converted into a columnar format.

The Power of the Binlog Ecosystem: MySQL’s "dual-log" mechanism (Binlog and Redo Log) is a double-edged sword; while it impacts raw write performance, the Binlog provides unparalleled support for the broader data ecosystem. By providing a clean stream of data changes, it facilitates seamless replication to downstream systems. This is precisely why OLAP solutions like ClickHouse, StarRocks, and SelectDB have flourished within the MySQL ecosystem.

Seamless HTAP Integration: When using DuckDB as a MySQL storage engine, the Binlog ecosystem remains fully compatible and intact. This allows the system to function as a data warehouse node that can still "egress" its own Binlog. In an HTAP (Hybrid Transactional/Analytical Processing) scenario, a primary MySQL node using InnoDB can stream Binlog directly to a downstream MySQL node using the DuckDB engine, achieving a perfectly compatible and fluid data pipeline.

So the question becomes if it was done knowingly or recklessly, hence a police raid for evidence.

it's truly a bismal experience compared to what else is out there (my experience is with rust, python and ts inside vsc).

Often autocomplete is hopeless and doesn't help you with the most simple things like picking from multiple initializers, or changing to a different signature of a function call.

the project setup is this mystery Xcode project file, instead of a standardized yml or something that anyone can modify and understand.

I have to say provisioning has improved a lot. I remember back in 2008, it was really a pain to get anything working.

This is not necessarily about Xcode, but maybe it should be: screen shots for your app. they need screenshots for 454 device types, and zero automation in their own tooling.

the layout is also very inflexible. they dictate a couple of panels and that's how you _must_ use them. that's unlike any other modern IDE.
Ask HN: Does anyone keep prompts and reasoning as part of dev cycle?
by sshadmand | 2026-02-04 07:37:10+00:00
We've never been able to read developers' minds, so we relied on documentation and comments to capture intent, decisions, and context even though most engineers dislike writing it and even fewer enjoy reading it.

Now with coding agents, in a sense, we can read the “mind” of the system that helped build the feature. Why did it do what it did, what are the gotchas, any follow up actions items.

Today I decided to paste my prompts and agent interactions into Linear issues instead of writing traditional notes. It felt clunky, but stopped and thought "is this valuable?" It's the closest thing to a record of why a feature ended up the way it did.

So I'm wondering:

- Is anyone intentionally treating agent prompts, traces, or plans as a new form of documentation?
- Are there tools that automatically capture and organize this into something more useful than raw logs?
- Is this just more noise and not useful with agentic dev?

It feels like there's a new documentation pattern emerging around agent-native development, but I haven't seen it clearly defined or productized yet. Curious how others are approaching this.

First, thanks for your knowledgeable input.

Second, are you saying that we basically need to have a radiator as big (approximately) as the solar panels?

That is a lot, but it does sound manageable, in the sense that it approximately doubles what we require anyway for power.

So, not saying that it’s easy or feasible, but saying that cooling then seems “just” as difficult as power, not insurmountably more difficult. (Note that the article lists cooling, radiation, latency, and launch costs as known hard problems, but not power.)

They do have to be if they want to be approved by the FCC.

And btw Kessler syndrome applies to any orbital band. You've got the logic backwards. Kessler syndrome is usually only considered a threat for LEO because that's where most of the satellites are. But if you're throwing million(s) of satellites into orbit, it becomes an issue at whatever orbital height you pick.

I don't think that equating all open source work with volunteering makes sense.

Volunteering is defined by its charitable purpose for a public good, not by the specific skill used.

Let me try an analogy:

A chef who cooks a free meal for a homeless shelter is volunteering. That same chef publishing a recipe online or making a cooking tutorial is sharing knowledge, not volunteering. The act of 'cooking' or 'publishing' is neutral. It becomes volunteering only when the primary, direct, and organised purpose is to serve a charitable cause without expectation of personal gain.

Disclaimer: I have been consistently doing a lot of open source in the last 10 years. I would consider none of that as volunteering.

I just noticed that rustc_codegen_gcc has been accepted into the mainline Rust compiler, or at least the nightly builds.

https://github.com/rust-lang/rust/pull/151156

This means that you will be able to use either GCC or LLVM to build your Rust code with rustc (the main Rust compiler). That means you can compile your Rust for any platform that GCC supports.

This only addresses the first point in the blog post (architecture support) but it is an interesting development.

No one has managed to come up for an improvement for the zodiac system used in astrology. There's countless studies on it, all inconclusive at best, once subject to reproduction and meta analyses. Should we keep using, despite a lack of evidence, because there's nothing better? Why not just discount it completely? If discounting astrology completely is the right move, than so is discounting the NOVA system.

Show HN: Sentinel – a Pingora-based reverse proxy (inspired by River)
by raskelll | 2026-02-04 07:40:21+00:00
I’d been watching River (Pingora-based) and hoping it would mature, because I think Rust + Pingora (from Cloudflare) is a really solid foundation for a future-proof reverse proxy. Progress stayed quiet, so I started building the “practical reverse proxy layer” on top of Pingora myself: config/routing + operational defaults + a way to plug in extra request/response logic without patching the core.

Sentinel: https://github.com/raskell-io/sentinel

River: https://github.com/memorysafety/river

This is such an underappreciated fact. Lots of people think 20kgs overweight is normal, they'll call you skinny and tell you to eat more if you're a healthy weight. An adult man of average height should probably not weigh more than 80kg. It could be okay if you're very muscular but most likely you'd be better off losing a few kilos. And being extremely muscular to the point where your BMI says overweight isn't exactly good for your health either. Though probably better than just being fat.

The cost might be the draw (if there is one). Big tech isn't afraid of throwing money at problems, but the AI folk and financiers are afraid of waiting and uncertainty. A satellite is crazy expensive but throwing more money at it gets you more satellites.

At the end of the day I don't really care either way. It ain't my money, and their money isn't going to get back into the economy by sitting in a brokerage portfolio. To get them to spend money this is as good a way as any other, I guess. At least it helps fund a little spaceflight and satellite R&D on the way.

> .. and that opinion is a great explanation of why systemd won.

Completely wrong and ignorant.

> Turns out, a lot of people are not happy with "Come on man. It's been done for decades." attitude, and they wanted something new and much better.

And then they got systemd. LOL

Like Dr. Phil said, "How's that workin out for ya?" LOL

> And so when something new came up, they jumped on it with both feet.

You just did what your type always does: whatever you're told.

> It's instructive to read Debian CTTE discussion on init systems

No, it really isn't. lol

> the choices were either upstart and systemd. And between two of those, systemd is a clear win.

Well, it's too bad none of the other good options were considered, isn't it? When your only "options" are a giant douche or a turd sandwich, the outcome can't possibly be good.

See U.S. presidential elections for one of the best examples of this dynamic. Two complete fucking losers are presented every time, and 40% of the population are mesmerized by the spectacle and think there can be no other possible options at all. That's you.

The fact is, many of you noobs don't even know how to write a shell script, yet somehow feel qualified to comment on this subject, as if your opinion is worth anything at all.

How many daemons have you personally written? Hmm? Do you even know how to write any C at all? Daemonizing a process isn't rocket science. It's a double fork. So simple even you could do it, I bet.

The problem is you're too technically ignorant to understand that none of your "technical" arguments hold any water at all. It's just you repeating the bullshit you were told, as usual.

Every Big Lie being told relies on Useful Idiots like you to help support it.

Logging is not difficult. Double forking is not difficult. If you find any of that to be a challenge, you're not qualified to write a daemon. If you can't successfully set up and run something like runit or any of the many other good sysvinit alternatives, you're not qualified to administer a Linux system. Period.

You make all these appeals to authority ("highly technical people" saying this or that) like that means something. You forget that you're speaking to the guy who built his own operating system. I don't need any guidance from "highly technical people" on what init system to pick. Apparently you're the type who does.

That's what your entire argument basically boils down to--one giant appeal to authority.

If everyone else was jumping off a bridge, would you do it too? Of course you would, without a moment's hesitation. Because you're a God damned lemming.

Now get off my lawn.
