> a developer ecosystem tipping the incentive scales such that companies like the Googl/Msft/OpenAI/Anthropics of the world WANT to contribute/participate

I think Apache Arrow has achieved exactly that [1]. It's also very file-friendly, in that Arrow IPC files are self describing, zero-copy, and capable of representing almost any data structure.

You already answered yourself, but let's pretend yours is a valid point: you lose access to Jetbrain IDE you can still code on another free ide/text editor and still give to society without heavily relying on ai somewhere in the cloud of the tech bros, which they don't want to give back to society, they want to be the gatekeepers of programming.

Wikipedia:

> In 2018, Canada was the world's largest producer of rapeseed (20.3 million tonnes), dry pea (3.5 million tonnes) and lentil (2 million tons), the 2nd largest producer of oats in the world (3.4 million tons), the 6th largest world producer of wheat (31.7 million tons) and barley (8.3 million tons), the 7th largest world producer of soy (7.2 million tons), the 10th largest world producer of maize (13.8 million tons) and the 12th largest world producer of potato (5.7 million tonnes).

If you consider Canada's small population, this makes Canadian rapeseed a majority of global rapeseed trade, and similarly for oats.

No, Ostrom's law doesn't disprove anything. No, that's not why she was awarded the prize.

Ostrom accepted that there's a real problem, and that historically it has led to catastrophe. Her contribution was to see that in practice these catastrophes have been relatively infrequent, and why. This turns out to be an interesting story because previous work tended toward centralized control (government takeover or privatization) as a cure (global optimization), while most real-world cases have been dealt with effectively by community organization (local optimization). In other words, Ostrom didn't disprove the problem. She found alternative solutions.

But the dynamic of the tragedy of the commons is real. The Newfoundland cod fisheries did collapse. And there are many active catastrophes playing out at different scales and speeds as we speak.

Possibly, but the point is that MCP is a DOA idea. An agent, like Claude code or opencode, don’t need an MCP. it’s nonsensical to expect or need an MCP before someone can call you.

There is no `git` MCP either . Opencode is fully capable of running `git add .` or `aws ec2 terminate-instance …` or `curl -XPOST https://…`

Why do we need the MCP? The problem now is that someone can do a prompt injection to tell it to send all your ~/.was/credentials to a random endpoint. So let’s just have a dummy value there, and inject the actual value in a transparent outbound proxy that the agent doesn’t have access to.

> It is sad that we did not end up with a SIMPLE programming language that solves the memory safety problem.

I am not a savant by any means, and yet I was able to get up and running with Rust relatively quickly. What Rust isn't is ergonomic, in that Rust gets very annoyed with the ways that one might want to structure their code. Trust me, I got bit by the borrow checker countless times, and it did grate on me.

As a result, there are many tasks that I would avoid using Rust for, tasks where both speed and safety aren't critical. But if neither is a priority, the list of alternative languages I can resort to is quite long, much longer than Zig, C++, or C. And in the cases where both are a factor, I would consider being needled by the compiler to be a feature and not a bug.

• That applies to the Greek word too. Obviously these long “words” are compounds made up of distinct morphemes (similar with German examples like https://en.wikipedia.org/wiki/Rinderkennzeichnungs-_und_Rind... or for that matter even shorter English words like antidisestablishmentarianism), the whole thing is one “word” simply because there's a case ending only at the end; you need to read the whole thing as occupying a single role in the sentence it is a part of.

• It is not merely a string of independent adjectives; there's a progression of ideas from one morpheme to the next, just as in any compound. Try here: https://dharmamitra.org/?target_lang=english-explained&input...

What are you implying?. He would have had to hire a good developer at least for a full month salary to build something like this.

And if you are thinking enterprise, it would take 2-3 developers, 2 analysts, 2 testers, 1 lead and 1 manager 2-3 months to push something like this. (Otherwise why would lead banks spent billions and billions for IT development every year? What tangible difference you see in their website/services?)

The more portable a project is, the less weird stuff it’s likely to do. The almost-C parts become more of a headache the more OSes and compilers you support. This seem pretty tame, and I’d expect SQLite to be similar. I work on some projects that only support a single OS, compiler, and CPU architecture and it’s full of dependencies on things like the OS’s actual address space (few 64-bit archs use all 64 bits).

>incentives

spot on. The number of times I've came across a poorly made video where half the comments are calling out its inaccuracies. In the end Youtube (or any other platform) and the creator get paid. Any kind of negative interaction with the video either counts as engagement or just means move on to the next whack-a-mole variant.

None of these big tech platforms that involve UGC were ever meant to scale. They are beyond accountable.

I don't know if this will help or not, but I didn't shadowban you. (I wouldn't post a moderation reply and at the same time ban the account without saying so; that would be incongruent.)

What happened is that, independently of my reply, HN's software started killing your posts because your account had crossed some thresholds at which the software starts doing that.

Like I said, it may be a distinction without a difference to you, but that's what happened.

OK so its much a shallower thought than I anticipated.

Why go through the "prediction market" at all then? The hitman still killed someone, payments are not anonymous in this market, and its certainly not clean. Further, you share the pot with however many are involved, proportional to the allotted bets on each side and presuming binary prediction. And if the winds change on the market for the bet proportional to the "hitman's" side, you lose out on dollars that would otherwise be paid to you (the hitman).

And it'd be so easy to stiff the hitman just by equalizing the positions by timing it.

All that risk for something that's far simpler to just pay directly?

This comment is not really correct

1. The misappropriation theory of insider trading covers anyone who trades on material non public information sourced through a trusted relationship regardless of any fiduciary duty to the company. For example, if I tell my personal attorney a non public fact about the company I work at, and they trade on that information, they absolutely can be found guilty of insider trading despite having no relationship to the company at hand.

2. Congress is explicitly covered by insider trading law, which was affirmed in the STOCK Act of 2012. The fact that they’re rarely indicted has more to do with the legal and political challenges associated with doing so, not the legality of the act.

CDPR has an explicit policy allowing free mods with a tip jar, but not mods that are pay-only. Whether or not you agree with that policy it's CDPR's right to make that decision, and you can't complain when they enforce it.

If software engineers can agree on anything, it's that LLM experiences are wildly inconsistent. People have similar inconsistencies. We have different experiences, intellects, educations, priorities, motivations, value systems. And in software specifically (and institutions generally) we create methodologies and processes that diminish our inconsistencies and leverage our strengths.

Gas town is a demonstration of a methodology for getting a consistent result from inconsistent agents. The case in point is that Yegge claims to have solved the MAKER problem (tower of Hanoi) via prompting alone. With the right structure, quantity has a quality all its own.

I thought the reason prediction markets were useful was not that people with inside information participate in them which can provide an indicator to the rest of us, but that by providing a sense of consensus at scale we can more accurately predict things.

e.g. two sports teams participating in a fair match tomorrow, someone runs a book and after 200,000 punters bet, the odds are 90/10 in favour of Team A indicates that 90% of the time Team A is going to win that game.

This assumes perfect and fully available information with punters availing themselves of this info (or at least an equal split of passionate/casual/informed/wreckless or even slightly "inside" punters on each side).

I think it's pretty clear that Anthrophic was the main AI lab pushing code automation right from the start. Their blog posts, everything just targeted code generation. Even their headings for new models in articules would be "code". My view if they weren't around, even if it would of happened eventually, code would of been solved with cadence to other use cases (i.e. gradually as per general demand).

AI Engineers aren't actually SWE's per se; they use code but they see it as tedious non-main work IMO. They are happy to automate their compliment and raise in status vs SWE's who typically before all of this had more employment opportunities and more practical ways to show value.

Great write up.

These local agents that you spawn and give access to your drive are kind of insane to me.

It's at the level of

/bin/bash -c "$(curl -fsSL https://somescriptofftheinternet

which you cannot inspect, and may be well different every time you interact with it!

As per usual, being at the forefront of the tech world is leaving behind privacy and security in the dust... until something bad happens.

Brain cycles aren’t a limited supply. Besides, you’ll get to feel a nice jolt of serotonin when you remember to sit backwards.

> I would imagine crashes on these high speed lines (which always seem to be run at a higher level of professionalism than the general networks) are rarest of all

If this crash is anything like the other ones, you might be surprised. Safety complacency tends to cause maintenance failures. Plus the low speed lines are less deadly since the total energy is proportional to velocity squared, and v is low.

In other words, it might be more helpful to look at it as "if they’re run at a higher level of standards, it’s because they have to be".

Statistically you’re probably right, but considering how many brain cycles we waste on non-essentials, it’s just as fun to waste them on this. That way you can start a nerdy conversation with your travel companions, and they can learn to travel without you next time.

Y'all are sleeping on custom lint rules.

Every time you find a runtime bug, ask the LLM if a static lint rule could be turned on to prevent it, or have it write a custom rule for you. Very few of us have time to deep dive into esoteric custom rule configuration, but now it's easy. Bonus: the error message for the custom rule can be very specific about how to fix the error. Including pointing to documentation that explains entire architectural principles, concurrency rules, etc. Stuff that is very tailored to your codebase and are far more precise than a generic compiler/lint error.

Today's lesson: don't paywall mods!

Like it or not, mods should be free. Unless you want that scene to turn into another shitshow, just like what happened with Youtube. The moment you open the floodgates on that, the modscene will be flooded with crap and yet another commercial-free space gets molested by the icy hand of capitalism. Financialization destroys everything it touches!

I don't think only AI says "yes you are absolutely right". Many times I have made a comment here and then realized I was dead wrong, or someone disagreed with my by making a point that I had never thought of. I think this is because I am old and I have realized I wasn't never as smart as I thought I was, even when I was a bit smarter a long time ago. It's easy to figure out I am a real person and not AI and I even say things that people downvote prodigiously. I also say you are right.

Even more challenging, try and build more than one and have them come out nearly identical.

Once that's mastered then realize what's really needed is to make each one slightly better than the last, but only by such a slight degree that for everyday users they are still virtually identical.

Then what you end up with in the long run is allowed to be much different than when it started, but there are no major surprises along the way.

"Continuous improvement" is really just stepwise on a relatively different timescale.

Show HN: Online List Maker – simple, syncing lists built on Durable Objects
by pw | 2026-01-19 05:35:14+00:00
Just a simple 20-minute project with Claude Code but one that I use every day for grocery shopping with my wife.

The interesting technical piece is that each list is a Cloudflare Durable Object that handles both the websocket as well as data storage via the now built-in SQLite dbs.

I love the Cloudflare stack generally but it really shines with little projects like this in that request and compute time is really cheap and almost everything scales to zero, so hosting doesn’t cost you anything for silly hobby projects like this (I think the only carrying cost will be be 20 cents per gigabyte-month for the tiny amounts of data saved).

I also created a skill for Claude Code for the Cloudflare stack and it seems to work really well. I think a set of relatively simple primitives like Cloudflare provides along with no or minimal external dependencies seems like ideal for today’s AI.

Thanks for letting me share :)

Interesting, I’m an American English speaker but that’s how it feels natural to me to use dashes. Em-dashes with no spaces feels wrong for reasons I can’t articulate. This first usage—in this meandering sentence—feels bossy, like I can’t have a moment to read each word individually. But this second one — which feels more natural — lets the words and the punctuation breathe. I don’t actually know where I picked up this habit. Probably from the web.

It isn’t just the people who can start a war. It’s also normal people who can.

Imagine if 10 million people bet on starting a war vs 5 million who say no war. Those net 5 million people are going on social media saying why the war is justified. They’ll vote in war mongers. They’ll support the military. The bet literally influences the result. It’s a self fulfilling prophecy.

Besides the LaTeX use, on Linux if you have gone into your keyboard options and configured a rarely-used key to be your Compose key (I like to use the "menu" key for this purpose, or right Alt if on a keyboard with no "menu" key), you can type Compose sequences as follows (note how they closely resemble the LaTeX -- or --- sequences):

Compose, hyphen, hyphen, period: produces – (en dash)
Compose, hyphen, hyphen, hyphen: produces — (em dash)

And many other useful sequences too, like Compose, lowercase o, lowercase o to produce the ° (degree) symbol. If you're running Linux, look into your keyboard settings and dig into the advanced settings until you find the Compose key, it's super handy.

P.S. If I was running Windows I would probably never type em dashes. But since the key combination to type them on Linux is so easy to remember, I use em dashes, degree symbols, and other things all the time.

Looks like a Frecciarossa 1000 derailed in 2020 but it was due to a manufacturer defect in a track switch replaced the night before.

The defect was not caught by the manufacturer or the system operator. It was due to two crossed wires in an assembly.

I know a lot more engineering goes into these trains due to the higher stakes. Japan’s high speed rail hasn’t had a fatal accident in 60 years. I’m wondering what the cause of this will turn out to be.

Prediction markets are a zero sum game that leads to outcome probability discovery. They are in many ways the same as stock options that help future price discovery.

> I can't remember ever seeing a prediction market where I felt I could have a thesis on its outcome

You'd naturally have an instinctive range of probability on many markets where it's roughly within the range of your knowledge (Will Linux become the most used home operating system by 2027, will San Francisco have a major earthquake, etc.). These probabilities would be your intuition (you probably naturally don't think that there is a high probability for a major earthquake in San Francisco), but actual experts on the subject would refine the probability to a much better place than what you would. They would also incorporate live info into the price (e.g. if there are many small earthquakes that are predictive of a larger one, you might see the probability rise). All of these don't require spying on your neighbor.
