I don't think the results of the last two decades of mass information dissemination have been all that great. People didn't trust anything on the internet before GPT, and the internet was already a cacophony of screeching voices too. Smart people were already decoupling from social media, and moving meaningful interaction to enclaves well before ChatGPT became a factor. ChatGPT did not ruin the internet, it was unleashed on a broken internet to begin with.

If, as this article predicts, the result of GPT is that we don't trust information from the internet, and everybody moves away from it, that's great. Traditional journalism was better, as it turns out. Talking mainly to your friends rather than millions of people was better, as it turns out. I'm ready to go back to that, should it come to it.

But it won't. This essay is making a catastrophic prediction that won't come to pass. Whatever the future is, it's going to be something nobody is predicting yet. It'll be better than the doomsayers predict, and worse than what the cheerleaders say. It will be nothing like a simple magnification of the present concern over epistemology.

A while back I saw an RF lightning detector on HN (https://techlib.com/electronics/lightningnew.htm)

I redesigned it to be much smaller and cheaper (surface-mount), made it an IoT device, and various other changes. Will order PCBs in a bit, hopefully it works well.

We don't have anything like Blitzortung in SE Asia as far as I know, and it would be pretty useful to me to detect lightning storms before they hit. The obvious application is to add it to my motorbike (driving a motorbike in a heavy storm is a necessary but miserable part of life here).

Bigger picture, there's no market for it, simply because it's cheaper to not buy one (I live in a very cost-driven market). However it would be useful to me personally.

The ideal scenario is that a responsible security engineer finds the problem, and doesn’t cause a power outage. Power outages aren’t necessarily just an inconvenience, they can cause serious economic damage, and kill people.

I think there’s a better solution somewhere in between doing nothing, and letting bumbling idiots recklessly fool with things they shouldn’t be messing with.

> That can be improved by making traditional investments (real estate, land) less attractive while making investments into businesses more attractive. You just need to change tax incentives by removing capital gain tax and introducing real estate/land value tax (or raising it). Removing red tape would help as well and then making the common market really common.

That's unrealistic. Majority of people in the EU own property and/or land, and no one wants to pay even more taxes on it. In my EU country, the majority of politicians own more than two apartments. I don't see them working against their own interests.

My design process is heavy on prototyping directly in code. I usually start off with sketches in pen and paper and then a quick mockup of the UI directly using Swift code since my apps are for iOS and Mac only.

I don't have any testers on this new version at the moment, but I'm considering having some beta testing once I get closer to release. No videos either, but I'm planning on writing some blog posts going over some of the UI flows and new features in the app to help with promotion. Once I polish the lesson UI a little bit, I'll probably post a video on YouTube of it too.

The point of jj is to improve on the git interface. It's kind of weird to imply that jj's purpose is a drawback. I don't want git to stay git. Nor do I want SAAS solving stacked PRs for me, "free option" or not.

jj is explicitly not for teams - there's no way to share jj-proprietary stuff between checkouts of a repo, because it's a frontend for interacting with a git repo.

That, and also how they expect to keep any species they manage to "bring back" alive (use of quotes because even that is questionable; the recent stunt with the "direwolves" didn't really create direwolves).

Which ecosystem are these species going to inhabit? How can we keep them alive when other currently existing species are at risk or going extinct?

Yeah, it's an interesting concept. The downside is that even if the user does sign in via oauth 2, there's no way that the model can persist the access token for subsequent calls (unless, idk, OpenAI/Gemini/others built persistence for access tokens obtained like this in their own tool calling infra, i guess it's possible)

What you could do is maybe create and host your own token storage, include a tool to retrieve it from within each kodec.txt file based on some reference id cookie in the browser, and see how far you get there

>what does it feel like to have 90% code/abstraction with 10% of visual sketch input

I was playing around with automating some aspects of architectural model making a few years back. I was using grasshopper (because I am an architect and can't really code). I found it interesting at the time, that the program encourages you to play with the ratio of visual-to-programmatic metric, but that ratio also reinforces how you interact with the project.

It was pretty simple stuff.. automatically unfolding meshes for paper cutting, adding tabs and rebates to sheet material for more precise joins, tagging elements for correct assembly, sorting elements by size and shape and using some basic genetic algorithms to optimise orientation and position on sheets to minimise time and material wastage.

But it really got me that when you push the programmatic elements to be more precise and repeatable, you really close down the problem space. When you increase the visual feedback, you tend to do it at the expense of precision and repeatability - your process becomes more tightly coupled to the specific project at hand.

Anyway, I am def going to have to make some time to try some of these out.

> Why would growing corn for ethanol and burning it in an engine be any climate-friendlier than growing that same corn for food and burning an equivalent amount of gasoline in an engine?

Because, doh, you would grow orders of magnitude more corn than you would just for food or feed.

Also, if you simply take away food corn, using all corn for nothing but biofuels, a substitute has to be found for food/feed uses of corn.

Food-versus-fuel reasoning about corn in the context of determining whether it is climate-friendly basically doesn't hold up. It leads to absurdities like contemplating whether biofuel from an inedible plant is better for the earth than biofuel from one that can instead be eaten.

IMO, I2P and Tor were never a solution to this, they are anonymization networks, which adds their own requirement on how to use it, and most people don't need anonymization. These protocols are slow and complex, thus not user friendly.

Maybe aiming a lower tier of security (like what TLS offers) is good enough for regular user. For example, Matrix or Jami.

But the problem with Matrix and Jami is that these are still too complex for regular user. No user, no motivation for the developer and it's a downward spiral from there.

All of this at the end reduces to a simple fact at the end of the discussion.

You need some of way of precisely telling AI what to do. As it turns out there is only that much you can do with text. Come to think of it, you can write a whole book about a scenery, and yet 100 people will imagine it quite differently. And still that actual photograph would be totally different compared to the imagination of all those 100 people.

As it turns out if you wish to describe something accurately enough, you have to write mathematical statements, in other words statements that reduce to true/false answers. We could skip to the end of the discussion here, and say you are better of either writing code directly or test cases.

This is just people revisiting logic programming all over again.

This one's pretty amazing to see, given how close it is in appearance to the Ergodox and other "glove keyboards" (rather, the other way around—they all resemble IBM's patent!).

While the buckling spring switches used in the Model M (or, for those with more rarified tastes, Model F) are rightly lauded, the beamspring is less well-known. The individual modules are absolutely massive as far as keyswitches go, but they feel wonderful to type on. They were designed to evoke the Selectric so as to be familiar to new users, and some models, such as the 3278, even included a solenoid that would click with each keypress. They also featured doubleshot keycaps and were absolute bricks that make the Model M seem a featherweight by comparison.

Yes, evolution and disruption will happen. Investing into "better" products is relative, but depends upon how much enshittification has occured in said market/markets versus expectation of the market. Monopolistic/oligopolistic market players have lower incentive to provide quality as their customers are captives. Just look at the kidney dialysis market or health markets where customers are often worse off after "consuming" the product than before. Appetite for disruption is present in markets with some form of equilibrium that is not aligned with expectations of the customer.

The VC industry will evolve, but many individual firms will not be given a chance by LP's. There is a tension between marketing TVPI and DPI to LP's. In up markets, LP's are less concerned about returns and get excited about markups, probably because there is likely to be a buyer later on. In down markets, LP's feel overexposed and DPI means everything.

Later stage VC's seem to be more susceptible to cyclical disruption in the market. Earlier stage VC's are also impacted, but there is a longer delay and portfolio companies have more headroom. Earlier stage VC's are less susceptible on the porfolio side, but exit periods will lengthen. Cyclical disruption rears its ugly head in several forms: LP funding and portfolio company success. Approaches in portfolio structure in a zero interest rate environment is different from what happens in a more "normal" environment. "Better" well known funds are more likely to see funds, but with a lower expectation returns. Emerging managers who may be closer to the opportunities in a new wave of tech often realize better returns on average, but they are unknown by LP's and seen as riskier.

Exit hypotheses and odds help build an idea of how the math works in a portfolio. Smaller/earlier stage VC's have more exit options: acquisitions, 2ndaries, and IPO's. Few companies can scale to a point where established/larger VC's will be happy with the returns. But, we're entering an environment where economics of the entrepreneur side are changing and this will also apply to VC's. With the new generation of tools, VC's don't really need to buy up a bunch of tools to manage their funds if they have the means to build it themselves. Small VC's don't have a budget to pay for tools.

But VC funded companies form a small slice of innovation in economies. There are bootstrapped and angel funded deals. There are companies that start on public grants, in garages, and in university settings. The environment we are going into has lower barriers to entry in all kinds of crazy ideas, so there are many opportunities that are more possible now than they were before.

Trump is a complicated-bad subject. It's required to have a realist position on him: he has a feral sense of populism --- it is malignant long term --- he is very good at social media is as you well explained. There is a sense in which Trump has more street smarts, and frankly, was more willing to go to the mat. That's easier when you dont care about anything except for winning. Again, ultimately not good for the US ... but short term good for MAGA.

As to what to do about it: I feel like we need now in politics what some of the enlightenment movement emphasized then: real, rational, substance. We have got to get to place where pretty boys talking BS rhetoric on TV is toxic. Having a talking point for complex subjects isn't good enough anymore.

We want results: a 10 year fiscal plan so debt doesn't swamp the federal budget; operational control of the border with immigration allowed; equal justice under the law including corporations and connected people. I want more Americans asking congress: where's the beef?

Right now Congress are not statesmen; they'll have to have to be told by the electorate to do better at running the country. They simply won't do it without that pressure. Most people are +/- 20% of center. We have more in common and we're in larger numbers: forget political parties; we want the fundamentals handled.
Show HN: A semantic code search tool for cross-repo context retrieval
by hpbyte | 2025-07-28 03:15:07+00:00
I’ve been frustrated trying to get the right context when working across multiple repos in AI assisted software development.

So over a weekend, I built h‑codex – a tool that can pull context from scattered repos into Cursor / Claude Code (integrated via MCP); ensuring that they’ve got the full picture when doing the plans/implementation.

How it works:

- Indexes the repos - Chunks code with AST for optimal chunk boundaries - Generates embeddings and stores them in pgvector for fast semantic search

Check it out: https://github.com/hpbyte/h-codex

The federal government alone spends $1.9 trillion annually on healthcare. That's enough to buy almost a million Tomahawk missiles every year. The total production will be around 9,000 missiles over 46 years, or less than 200 per year. We do not meaningfully choose between paying for healthcare domestically and blowing up foreigners. Even overthrowing Iraq's government and trying to make it a democracy only cost about $2.4 trillion over 10 years.

It’s the latest in a series of homogenising inventions - the printing press, radio, television, the internet - that will probably result in people of the future speaking and thinking more similarly than today. First went minor languages, then dialects, now regional differences within languages. Next will probably be the difference between different English accents - I think by 2100 English speakers will all be speaking with a generically American accent no matter where they are on earth. Then next will probably be other national languages - 90% of Swedes and Dutch people already speak English.

It didn't really take off until WW2--Eisenhower warned us of the military-industrial complex in his last days in office, but chickened out of of military-industrial-congressional complex at the last minute apparently.

There was no real standing Army until WW2 since it's against the Constitution. That's why the Marines (part of the Navy) were all over the place supporting US business interests, but not draining the public purse too heavily (look up Smedly Butler for a good read)

Speaking of Javelin missiles, mentioned upthread. In 2022, when the war in Ukraine erupted, the small stock of Javelins which the NATO countries were able to provide was spent in like first several months. After that, $300 drones carrying a $1000 armor-piercing round started to dominate the battlefield, leading to terrible losses in Russian armor, especially the newest and most expensive tanks. Similarly, having lost a number of advanced and expensive aircraft, and watching advanced and expensive cruise missiles mostly shot down during airstrikes, Russian forces turned to expendable drones imported from Iran (!) and expendable rockets imported from North Korea (!!).

In other terms, Protoss-type technology works well when you have a large advantage and need to deal a decisive blow; an example would be B-2s bombing the Iran nuclear facilities. But when you're in a protracted conflict against a capable adversary, Zerg-type technology, cheap, flimsy, and truly massively produced, seems to be indispensable.

If you are going to blow something up, using these GPS guided smart missiles is actually much cheaper than previous generations of explosive ordinances.

1. You can only use one missile to hit a target. In pre-gps era we would would dozens or hundreds of rounds to ensure one of them destroys the target.

2. You can fire from a safe distance. Using artillery or dropping bombs from an airplane involves physically getting closer to the target. This introduces much more complexity that adds to the overall cost.

3. There is significantly less collateral damage when using a single missile for a target compared to bombing the general direction of the target.

4. We take significantly less risk of casualties when using these missiles.

Author could spend a lot more time learning how to use Autodesk Inventor sketch environment. You can setup sketch dimensions as ‘driven’ and use equations to comply to whatever exterior box dimensions one chooses. His creating assembly from parts and arranging is silly. All parts /solids should come from same master sketch.

And then also how to use Autodesk CAM, you can use sketch geo to set paths, define offsets, etc.

Interesting past tense. Why did you leave and does it involve getting paid more?

I've worked in government and it's just like the private sector. You have people that are there check in, make money, and go home, and you have people that care about their work. And I don't think there are any significant ratio differences between public and private in regards to that.

Not all security research is the same. There’s a lot of room for nuance in this discussion.

I think there’s a lot of things that many people would agree should be protected. For instance, people who report vulnerabilities they just happen to stumble upon.

But on the other end of the spectrum, there are a lot of pen testing activities that are pretty likely to be disruptive. And some of them would be disruptive, even on otherwise secure systems, if we gave the entire world carte blanche to perform these activities.

There are certainly some realms of security where technology can solve anything, like cryptographic algorithms. But at the interface of technology and society, security still highly relies on the rule of law and living in a high trust society.

Well obviously, these states know how bad the Russians are since they were terrorised by them for decades. They'll be the first on the chopping block. And they know that Europe does not have much deterrent of its own right now so they're screwed without the US. Though this will come.

I don't see the term stealing identity as something that implies I have done something wrong to allow it. If you have something stolen from you it doesn't mean you have done something wrong to allow that. If someone broke into a bank vault and stole your money it wouldn't be considered your fault.

The challenge in cyber security is that the person potentially stealing your identity lives on the other side of the world and that's why the focus is on the end user to be as secure as they can. But if you have something stolen from you, you are still the victim.

I’m talking higher level than that. Think about the acceptance criteria you would put in a user story. I’m specifically responding to this:

> When you give up the work of deciding what the expected inputs and outputs of the code/program is you are no longer in the drivers seat.

You don’t need to personally write code that mechanically iterates over every possible state to remain in the driver’s seat. You need to describe the acceptance criteria.

I have, however, scoured decades of court documents and police records (the joys of freelance IT work) and stand by the observation that the absolute worst people can be found everywhere .. including unseen within the most milquetoast seeming circles until that day when acquaintances voxpop "they seemed like such a nice person" statements.

You would do well to start by identifying the size of B you plan to sell to.

Selling to owners of < 10 employees) is very different to < 100 and so on.

If your business is tiny it can be hard to sell to a business that is large. The larger the business the more they evaluate your business as a potential long-term supplier and less about the product.

As you are starting out I recommend talking to smaller, rather than larger businesses.
