Mmmmmm, Black Sails…

Let’s not forget the slaves sent to the fields after Spanish conquest. Irish, African, Portuguese, Indian, all found their ways to the sugar canes.

That era was literally groups of humans exploiting every other group of humans they could find.

The first wave owners children found themselves going to war with the crown or being a member of the crowns second wave to further entrench the royal riches. It became extremely political.

These deals all look like classic “round tripping.” Is there any evidence that this activity is generating actual net new $ that didn’t exist previously?

Amazon’s recent earnings was full of apparent round tripping.

1. Amazon “invests” in Anthropic (cost)

2. Anthropic takes that money and buys AWS (same dollars come back as revenue)

3. Amazon builds big datacenter for Anthropic (cost)

4. Amazon records a large paper “profit” because the value of the Anthropic “investment” went up after all the stuff it’s doing with the “investment” from Amazon

Meanwhile none of the above appears to actually be making any actual profit in terms of revenues > costs.

It’s bonkers. These are the same sort of shenanigans that were going on with infrastructure prior to the .com implosion. Did we learn nothing?

To expand a bit on what others have said:

If you're counting up, round down. If you're counting down, round up. A human expects the count to finish at precisely the moment we get to the last number in the sequence (zero, for counting down). Do a count in your head to see what I mean.

Apple chose a compromise by rounding to nearest, for it to "feel good", but you lose the ability to exactly predict when the timer ends as a human. Typical Apple.

Hmm, what do you mean by current approach? This is new territory and agent safety is an unsolved problem, there is no current approach, except you mean not doing agent systems and using humans. The trifecta is just a tool on the level of physics saying "ignore friction", we assume the model itself is trustworthy and not poisoned most of the time too, but of course when designing a real world system you need to factor that in too.

I mean management is going to think the stock is always undervalued.

Slightly offtopic: If a company does a stock buyback because they think its undervalued, what happens next? Does the stock go up and they're satisfied? Does the stock go up and then they sell it?

If they're selling it to realize profits, I say that it tantamount to pump-and-dump. If they sell it just to hike the price, why not distribute dividends with their excess cash reserves?

It really looks like is it two thirds of what a Klipper-based 3D printer with a monitoring camera would need. It lacks the stepper controllers/power control stuff but it has the CPU/MCU duality you'd want, it could comfortably run a proper LCD panel, run an on-board slicer, even run on-board CAD.

This is why I harp about platforms needing to become decentralised and un-censorable

I wish people could handle such platforms responsibly. In practice, the first decentralised and un-censorable platform will be immediately overrun with CP and drug emporia. And I say this as someone who appreciates civic freedoms and libertarianism... Some people are genuinely shitty and have an "anti-Midas touch" which turns everything they touch to shit.

I tried Thunderbird first, but unfortunately it was kinda heavy and was fairly unreliable, which kinda tracks with my experience before (at least on Windows). Mailspring works fine and is also open source.

Couldn't find a decent minimalist calendar program that integrated well with Windows. People say they like OneCalendar but I refuse to use the Windows Store, I even got WSL set up without it lol

I'm a former Three user in central London. When I started it was good, then they advertised cheap unlimited data contracts which overloaded their system and they became close to unusable. You'd order an Uber, go down to meet it and be stuck because there was zero data. It wasn't a signal strength thing - it was a system overload thing.

I'm now on O2 which works kind of normally and also have a silent link esim which is a good backup. They cost like £8, never expire and let you use any UK network you choose if one isn't working. Or almost any network globally for that matter.

Interesting! I guess that's from your standard benchmark setup. Please note that Fil-C makes no secret of having a performance penalty. It's definitely a pre-1.0 toolchain and only recently starting to pick up some momentum. The author is eager to keep improving it, and seems to think that there's still plenty of low hanging and medium hanging fruit to pick.

It does (or did, at some point) pass the thorough SQLite test suite, so at least it's probably correct! The famous SQLite test coverage and general proven quality might make SQLite itself less interesting to harden, but in order to run less comprehensively verified software that links with SQLite, we have to build SQLite with Fil-C too.

> And I like FreeBSD jails.

If you don't know about them already, you may be interested in service jails (forthcoming[1] in 15):

> A service jail shares the complete filesystem tree directly with the host (the jail root path is /) and as such can access and modify any file on the host, and shares the same user accounts with the host. By default it has no access to the network or other resources which are restricted in jails, but they can be configured to re-use the network of the host and to remove some of the jail-restrictions.

For the past two years,I've been working on a complete system that moves us beyond globalized scarcity. It's not a theory. It's a manufacturing-ready, validated platform for post-scarcity infrastructure.

I've released everything: schematics, validation studies, and the licensing model. It's designed to be un-patentable and freely available to humanity, while offering a 10-year commercial window for serious partners.

The repo speaks for itself. I'm here to answer technical questions.

I have a script that searches DDG (free), scrapes top 5 results, shoves them into an LLM, and answers your question.

I wrote it back when AI web search was a paid feature and I wanted access to it.

At the time Auto-GPT was popular and using the LLM itself to slowly and unreliably do the research.

So I realized a Python program would be way faster and it would actually be deterministic in terms of doing what you expect.

This experience sort of shaped my attitude about agentic stuff, where it looks like we are still relying too heavily on the LLM and neglecting to mechanize things that could just work perfectly every time.

I think it may be fair? This guy[1] explains how surplus of corporate profits are a mirror image of household/govt debt. Which is a direct transfer of wealth from everyone to the super-super-rich (not the 1%, but the 0.1 - 0.01%)

[1] The chart below shows how this works. The blue line at the top shows the “surplus” of corporations: corporate income minus expenses and net investment. We know this as corporate “free cash flow.” The red line shows combined “surplus” of other sectors: government, households, and foreign trading partners – in excess of their consumption and net investment. It’s negative, so in aggregate, they’re running a deficit. That deficit is the mirror image of the corporate surplus. This isn’t an accident. It’s just accounting (I’ve excluded a few tiny items for clarity): https://www.hussmanfunds.com/comment/mc251028/

As someone who is on the dating scene after my wife died of cancer some thoughts:

1) There are a lot more men on the dating apps than women.

2) Using just pictures to judge men doesn’t really work for women. See https://archive.ph/20251006053755/https://medium.com/the-kno... for discussion.

My personal experience, based on what I’m going through and what friends have to say:

3) 17 years ago, it was possible to meet and know really attractive women on the apps.

4) These days, the really attractive women no longer use apps.

5) The apps are optimized for engagement, not giving people successful romance.

Right now, the woman I’m currently dating is someone I met at church, not on the apps. The men I know who have success with women prefer the women they meet outside of the apps.

As a shy geek without too many social connections, the apps (websites, actually) were a very positive game changer 17 years ago. These days, they are more a liability than asset when it comes to dating.

OTP is such a wonderful project! It's my go-to example of open source in government and it's so much more than a trip planning engine. For the country-wide transit app I'm working on (ok, it's a small country, but still), we use it as the database as well. We convert everything into GTFS(-RT), throw it into OTP, then have a fairly thin API layer that queries it via GraphQL and returns JSON for our app [0].

I also have to say the code is far more elegant and readable than what I expected from a 15 year old Java project. I had to fix a bug once and I figured it would take me at least a few hours to get my bearings in a codebase that size, but I managed to wrap my head around the core routing logic and fix the bug in an hour or so. The A* implementation for non-transit routing is such a good example of "enterprise code" done right.

>in 1994? You wish. Turbo C++/Pascal was widely used under DOS, things truly began to change with WIndows 95 and even until 1997 DOS wasn't fully dead because it had very complex uses with DOS extenders. Windows 95 was an unstable piece of crap and for tons of industrial cases tons of people booted it in DOS mode to launch really advanced software. By 1994 you would even get multimedia CD's made for DOS with ease.

Alas, I did attend, but dropped out. (as noted)

We also went on a bit of a walk back from the bailey to the motte. "sector in the tourism industry" to "tourism/finishing school aspect" (tourism ~= finishing school now?).

Then, a vague hand wave towards "wide reporting" for...the original idea that universities are tourism? Or one of the new ones, like universities have an aspect of finishing school? Unclear.

We all know of bubbles. Let's assume the idea of a bubble has not escaped investors attention.

Here is where I get confused:

- It does not seem very likely that all the people whose entire job it is to make these decisions are completely incompetent. Is it for some reason good to invest badly? How does this work in reality? Does it not matter if an investment goes to zero? Is every investment a good investment, because nvidia sells chips, is that how the math works here?

- Absolutely everyone and their mum talks bubble and supposedly can see it clearly (in contrast to for example the 2008 housing bubble) but nobody in power has the ability to act rationally. What the idea here?

- If it can be explained, that every investment is good now, and the answer to the previous question is something like "greed", why stop at a measly billion? Why not just, say, 10 billion? The money is there obviously. More "bad" investment = better?

...and, snap: Trump will get a cut, and that's the last we'll ever hear about acetaminophen and autism. Before you scoff, the mere fact that the deal is happening right now, after a campaign of attainder originating from the head of state, proves collusion long in advance. If it were otherwise, the price would be mills on the dollar.

GPT5 was by no means a huge leap. I’d be willing to believe that you prefer it, or that you found it an improvement, despite both of those being wildly contrary to my experience (and most of the rhetoric online). But objectively speaking it was a small improvement, even going by OpenAI’s marketing claims.

In practice, I upgraded everything to GPT-5 and the performance was so terrible I had to rollback the update.

With 70%+ profit margins on data centers, it's enough that just $1.43 billion in data center revenue is secured for $1b investment to pay back.

Nvidia's larger investments are even more conditional. With OpenAI, the investment is contingent on building huge data centers in the future. If the bubble ends, Nvidia pays nothing; if it continues, Nvidia has locked in a customer.

Nvidia plays smart with little risk.

No. You can replace them with asterisks to mean 'any length is fine', but you can't at compile time check something that's only known at runtime (granted, you could see that it can't match if the variables are, for example, an (Integer 1 10) and an (Integer 75 100)). Something you can do with variables is:

(defvar *example-dimension* 20) (deftype Example-Array (element-type minor-dimension) `(Array ,element-type (,*example-dimension* ,minor-dimension)))

...and then you can declare variables to be something like, say, (Example-Array Boolean 5) and have it expand to (Array Boolean (20 5)). But the type declaration needs to be of the form (Array &optional element-type dimensions) where dimensions can be any of the following:

- An asterisk, which means anything goes.

- A number, which means the array needs to have that many dimensions (so an (Array Fixnum 2) is a 2-dimensional array of fixnums).

- A list of numbers, asterisks, or a combination of the two, where an asterisk means 'this dimension can be anything' and the numbers mean exactly what you would expect.

Maybe something like that would be possible with Coalton, but I haven't played around a lot with that yet.

Windows locks files when they're in use, so that you cannot overwrite them. Linux doesn't do this.

So if you want to overwrite a running service then you can either stop it, update it, and restart it (tricky to manage if it has dependencies, or is necessary for using the PC), or to shut down everything, update the files while the OS isn't (or is barely) running, and then restart the OS.
Show HN: I built an AI that generates full-stack apps in 30 seconds

For the last 6 months, I've been building ORUS Builder, an open-source AI code generator.

My goal was to fix the biggest issue I have with tools like v0, Lovable, etc. – they generate broken, non-compiling code that needs hours of debugging.

ORUS Builder is different. It uses a "Compiler-Integrity Generation" (CIG) protocol, a set of cognitive validation steps that run before the code is generated. The result is a 99.9% first-time compilation success rate in my tests.

The workflow is simple: 1.Describe an app in a single prompt. 2.It generates a full-stack application (React/Vue/Angular + Node.js + DB schema) in about 30 seconds. 3.You get a ZIP file with production-ready code, including tests and CI/CD config.The core is built on TypeScript and Node.js, and it orchestrates 3 specialized AI connectors for different cognitive tasks (I call this "Trinity AI").

The full architecture has over 260 internal components.

A bit of background: I'm an entrepreneur from São Luís, Brazil, with 15 years of experience. I'm not a programmer by trade.

I developed a framework called the "ORUS Method" to orchestrate AI for complex creation, and this is the first tool built with it. My philosophy is radical transparency and democratizing access to powerful tech.It's 100% MIT Licensed and will always have a free, powerful open-source core.

GitHub:https://github.com/OrusMind/Orus-Builder---Cognitive-Generat...

My take is this is mostly a takeout of Amazon’s trainium program, helping Nvidia to cull competition from Amazon in its infancy.

Up until the date of the announcement, poolside was one of Amazon’s largest trainium customers, other than anthropic. This investment from Nvidia kicks one of the legs out from Amazon’s already rickety AI accelerator stool. 40 K in Blackwell GPUs is expensive even with the Nvidia investment. Poolside will likely not have the money to spend an equivalent amount now with Amazon.

I've heard this argument, but as long as there is some return then people will invest because some is better than none. VC investments have the potential to return insane amounts, so people will still buy those lottery tickets even if the profits are taxed. I know this because actual lottery winnings are taxed and people still buy those tickets in huge numbers. And if you are saying that taxing investments the same as worked income is 'super harshly' and 'ruinously' high, then what does that say about the state of wage taxes?

> Dammingly, you are forgetting about the cost of the external flash that it requires, when program flash is the main cost of MCUs. It shows you don't have much experience with this stuff.

If you had any experience "with this stuff", you'd know 16mbit of QSPI flash (compatible with rp2040) costs 7-8 cents in volume. 64mbits 12cents or less. And would calm your tits. It is okay.

> Besides how it looks like you weren't one of the early adopters

If you had any experience "with this stuff" you'd know better than to buy reels of mcus on rev1/rev2 that haven't been on the market for atleast a year or two.

> bottlenecked by a core without FPU

Why would lack of FPU impact bandwidth? Lack of FPU is non-issue with fixed point math in most cases.

> I have read the docs, and like I said the point of STM32 is ubiquity

And yet during chip shortages, rp2040 were one of the few MCUs without stock issues or crazy prices... in fact, I've never seen it out of stock. STM32 on the other hand... ouch. Fun times!

>This is what I'm talking about, like honestly what capability does that unlock for you beside party tricks?

So every capability and use-case that doesn't tickle your zoomer sensibilities is a party trick?

Okay.

VC investments are inherently high-risk, high reward. That is, most of the investments will go to zero, but hopefully one or two really good ones make up for it. In order to make that work, you have to invest in many different startups, which is what Nvidia seems to do.

Nvidia has the additional advantage that some of their invested money will make it back to them in the form of dollars spent on compute, which makes their investments cheaper for them, relatively speaking.

> If it can be explained, that every investment is good now, and the answer to the previous question is something like "greed", why stop at a measly billion? Why not just, say, 10 billion?

If the startup isn't looking to raise 10 billion, why give it 10 billion? Instead, give 10 startups one billion each, to spread out the risk.

The purpose of a stock buyback is to increase the shares value. This allows investors to choose to realize profits, but this is not a "pump and dump" because having less outstanding shares fundamentally drives the price up. There is nothing wrong with stock buybacks.

The reason this is often done instead of a special dividend is that dividends create an immediate taxable event for all investors, which is considered less flexible than the capital gains tax associated with a stock buyback.

Besides the tax treatment difference, it's mostly a signalling/communication choice: share buybacks increase EPS which is a nice story, whereas dividends signal reliable profits.

My RL trained multi-agent-coding model Orca-Agent-v0.1-14B reached a 167% higher relative score than its base model on Stanford's TerminalBench. I've open sourced everything.

*What I did:*

- I trained a 14B orchestrator model to better coordinate explorer & coder subagents (subagents are tool calls for orchestrator) - Scaled to 32x H100s that were pushed to their limits across 4 bare-metal nodes - Scaled to 256 Docker environments rolling out simultaneously, automatically distributed across the cluster

*Key results:*

- Qwen3-14B jumped from *7% → 18.25%* on TerminalBench after training - Model now within striking distance of Qwen3-Coder-480B (19.7%) - Training was stable with smooth entropy decrease and healthy gradient norms

*Training approach:*

Reward design and biggest learning: Kept it simple - *just unit tests*. Every "smart" reward signal I tried to craft led to policy collapse

Curriculum learning: - Stage-1: Tasks where base model succeeded 1-2/3 times (41 tasks) - Stage-2: Tasks where Stage-1 model succeeded 1-4/5 times

Dataset: Used synthetically generated RL environments and unit tests

*More details:*

I have added lots more details in the repo linked to this submission, including training code, model weights, datasets.

Huge thanks to: - Tara for providing the compute - Prime Intellect team for building prime-rl and dealing with my endless questions - Alex Dimakis for the conversation that sparked training the orchestrator model

Thanks for reading!

Access to infrastructure is a core part of the AI business.

If you are a startup, and you want to buy AI infrastructure, you would typically sell equity to a VC and use that money to buy infrastructure.

If the AI infrastructure vendor would offer to buy that equity, rather than a VC, that’s preferable because you may get ongoing special treatment from the vendor once they have a stake. So it’ a great deal for the startup.

For the infra vendor- you can likely get a good deal on the investment, you get some exposure to higher upside, and it may be useful to manage your cash flow.

Seems like strategic high value moves to me. It’s no wonder the market likes it

> Their life is shit already, that's why they act as they act, passing aggression on to others in vain effort to get rid of some of that 'evil' in them.

The exact same can be said for good ole Adi. And many of his ilk currently alive.

What you're saying isn't a straightforward universal truth. There's no one right answer. Some of the time, what you're saying is very true. Other times it's very much not. GP's reaction as such isn't "knee-jerk". The equation doesn't suddenly change the second the "evildoer" in question turns 18, or 21.
