I can't speak for lidar, but the Tesla self driving with cameras only on HW4 in my little Model 3 is so good that I don't even think about it anymore. I never thought I would trust this type of technology.

Over the last 2 days I drove from Greenville, SC to Raleigh, NC (4-5 hours) and back with self driving the entire way. Traffic, Charlotte, navigating parking lots to pull into a super charger. The only place I took over was the conference center parking lot for the Secure Carolina's Conference.

It drives at least as well or better than me in almost all cases...and I'm a pretty confident driver.

I say all that to say this...I can't imagine lidar improving on what I'm already seeing that much. Diminishing returns would be the biggest concern from a standpoint of cost justification. The fact that this type of technology exists in a vehicle as affordable as the Model 3 is mind blowing.

This isn't even whataboutism, because the comparison is just insane.

The difference between the CCP, where "private" companies must actively pursue the party's strategic interests or cease to exist (and their executives/employees can be killed), and the US, where neither of those things happen and the worst penalty for a company not following the government's direction (while continuing to follow the law, which should be an obvious caveat) is the occasional fine for not complying with regulation or losing preference for government contracts, is categorical.

Only those who are either totally ignorant or seeking to spread propaganda would even compare the two.

In the version I'm discussing, both parties already know the graph, so your point (B) seems irrelevant. The interrogator needs to know the graph in order to specify an edge (and to know that they've done so), so I'm not sure of the precise version you are thinking of.

Put point (A) is relevant ... certainly each call only provides a small amount of additional confidence, so a lot of calls might be required. Even so, the system seems sound to me, and I'd appreciate any details of ways in which it is not.

> How realistic is this though? Getting elected to Congress usually means having some other prior government experience, or your opponents attack you with "why would you give this person responsibility at a congressional level if they've never even worked in local politics?" Not to mention you need name recognition, a history in government that people can use to understand your values as acted, relationships in government to accomplish anything.

I would contend there are plenty of people in lower levels who can move up or not. Was the mayor of the next town over any good and thus I want to send them onto state congress? Was a library board member two towns over good and I want them in the US house? For that matter, do they run a good honest business (there are lots of businesses) that I can check out locally and thus I want to risk them.

The real key is that term limits need to apply to everyone and so nobody will bother asking about experience as there isn't anything more on their side to fall back on.

Though in the end you are probably right - doesn't mean I like it.

> As I get older it seems that liberal democracy basically requires career bureaucrats to function.

I agree, but the people in congress should not be the career bureaucrats.

Those with longer tenure though tend to end up in the powerful senate positions like becoming a majority/minority leader. Thus you end up with absolute fossils like Pelosi or McConnell who most recently basically snuck in banning hemp into the budget bill, which was something absolutely almost no one in the USA was calling for and incredibly unpopular.

I doubt a minority/majority leader with only 2 terms would be as good at snaking in this kind of stuff in, or snaking their way through the politics of various committees to kill off proposed legislation before it's voted upon, that takes practice to really get good at all the underhanded techniques.
Show HN: A $20/year invoicing tool for solo developers (simple, fast, no bloat)
by mightbefun | 2025-12-03 15:00:05+00:00
Hi HN! I built a super lightweight invoicing platform for solo developers, freelancers, and one-person businesses. Most invoicing software costs $20–$40/month and is packed with features you don’t need. Mine is $20/year and focuses on the essentials:

• Create invoices in seconds • Send invoices by email • Automatic email reminders • Recurring invoices • Simple dashboard for paid/unpaid tracking • No team features, no CRM, no bloat

I built this because I freelance occasionally, and every invoicing tool I tried either felt bloated, overly enterprisey, or was way too expensive for solo work. I wanted something simple that didn’t require a “plan,” onboarding flow, or learning curve.

A few things people have asked so far: • No lock-in — you can export your invoices anytime • No limits on the number of invoices • No weird pricing tiers or upsells • Works well on mobile • You own your customer list (I don’t touch it)

Here’s what I’m looking for from HN: • Brutally honest feedback • Any missing “must-have” features for solo entrepreneurs • Performance/UX suggestions • Security concerns I should address early • Whether the $20/year model feels right

If anyone here freelances or runs side projects, I’d love to know what your current invoicing workflow looks like and what annoys you about existing tools.

Thanks for reading — happy to answer every question!

Hey Alex,

I appreciate the time you taken to put into this job post. It says you're looking for an experienced developer but it also says in the post that you won't disqualify someone who doesn't have the qualifications and unfamiliar with all areas of technical competencies.

Guess the question is, are you looking for an experienced developer or open to folks of all levels willing to learn and get up to speed as mentioned in your post? And speaking of Greenarrow email, how can folks get in touch? Thanks

> As Venkatesh concludes in his lecture about the future of mathematics in a world of increasingly capable AI, “We have to ask why are we proving things at all?” Thurston puts it like this: there will be a “continuing desire for human understanding of a proof, in addition to knowledge that the theorem is true.”

This type of resoning becomes void if instead of "AI" we used something like "AGA" or "Artificial General Automation" which is a closer description of what we actually have (natural language as a programming language).

Increasingly capable AGA will do things that mathematitians do not like doing. Who wants to compute logarithmic tables by hand? This got solved by calculators. Who wants to compute chaotic dynamical systems by hand? Computer simulations solved that. Who wants to improve by 2% a real analysis bound over an integral to get closer to the optimal bound? AGA is very capable at doing that. We just want to do it if it actually helps us understand why, and surfaces some structure. If not, who cares it its you who does it or a machine that knows all of the olympiad type tricks.
Show HN: Testing hypotheses through prediction is the next step towards AGI
by judahmeek | 2025-12-03 15:01:04+00:00
Granted, all I've got so far is a Draft Specification for a proof of concept using ARC-AGI-2 as a minimalistic problem domain.

But that was enough for METR.org[0] for recently agree to fund my work on this project.

That little bit of validation goes a long way & the funding won't hurt either.

Also, I have questions for any patent lawyers reading this:

* When do I know if I have enough specification detail to start filing a patent?

* Does this public repository qualify as prior art?

Finally, if my post text seems overly sparse with the details, I apologize & I promise to answer any questions you have as fast as Hacker News allows me to.

Missed the boat? Have you been living under a rock? Watson AI advertising has been everywhere for years.

It’s not that they aren't in the AI space, it’s that the CEO has a shockingly sober take on it. Probably because they’ve been doing AI for 30+ years combined with the fact they don’t have endless money with nowhere to invest it like Google.

To avoid hitting HN's rate limit, I will be adding my answers to this post for as long as I am able to edit (2 hours, I think). Once I am no longer able to edit or have hit a character length restriction, I will create a reply post to this one and do the same thing there.

Also, to reduce confusion, the original title was "Show HN: A belief system is how we create AI that actually think like humans do"

Answer to taylodl's question[0]: AI will never be able to think exactly like humans do. There will be trade-offs to this. However, enabling AI to think more like humans will enable both AI & humanity to better explore these tradeoffs.

I feel async is in a very good place now (apart from async trait :[ ) As a regular user who isn't developing libraries async is super simple to use. Your function is async = it must be .await and must be in an async runtime. Probably as simple and straightforward as possible. There are no super annoying anti-patterns to deal with.

Yeah, I'm with sateesh in a sibling comment in that this is a win for the digital citizenry's awareness, but I also agree with you that when the EU caves in everyone else will follow.

And I'm sure in the end it will cave in. The "they" have a clear plan supported by infinitely more patience and resources than the "us" can muster, and the von der Leyen presidency has shown clear signs of direction towards more control, less privacy (by weakening the GDPR), and less of the good kind of regulation in industry.

As an EU citizen, I'm very unhappy with the Union's recent direction.

But, at least for now, hooray for the temporary victory on the Indian front!

Compete for talent. You can never compete with big tech salaries, and often you can't compete with their benefits either. But you can still compete in creative ways. The most obvious way that no one does is to promote people into lower hours worked; instead of a pay raise you give them every Friday off, for example. There are a lot of types of people out there motivated by a lot of different things than money.

You are missing that each update takes AGES while it tortures your disk for patching the files (on my machine it takes 15min or so, and that's on an SSD). So I agree that this is careless and reminds me of the GTA5 startup time that was fixed by a dedicated player who finally had enough and reverse engineered the problem (see https://nee.lv/2021/02/28/How-I-cut-GTA-Online-loading-times...). I still find these things hard to accept.

This readme reads like I already know the project, what it does, what problems it solves, and how it works.

> A precise project scheduling engine with minute-level accuracy for resource allocation and dependency management.

I have no idea what that means.

I write firmware, so does that mean this project is a scheduler for a while(1) based mcu project?

> pip install scriptplan

Oh, it's python. ok, so it's a "resource allocation and dependency management" engine.. for a python project? I mean, I'm using pip to install it, so it's not a daemon style engine that my project can hook into, right?

> # Generate JSON report to stdout

> plan report project.tjp

Oh, it IS some kind of daemon or service that runs when I install it with pip?

> Certification Level: Airport-Grade / Mission Critical

Okay, so is there a standards bureau that certified it? if so shouldnt there be a certification number somewhere? then maybe I could figure out what this does.

Read to the end, I still don't know what the first line in the readme means. Maybe I need to look up 'TaskJuggler'?

Disservice? Rust is taking over the world while they still have nothing to show basically (Servo, the project Rust was created for, is behind ladybird of all things). Every clueless developer and their dog thinks Rust is like super safe and great, with very little empirical evidence still after 19 years of the language's existence.

Zig people want Zig to "win". They are appearing on Hacker News almost every day now, and for that purpose this kind of things matters more than the language's merits themselves. I believe the language has a good share of merits though, far more than Rust, but it's too early and not battle tested to get so much attention.

Ok, I think we're actually in agreement -- given your all-important qualification "for the range 200ms-1s". Yes, ofc, that first part of the curve above the drop is quite flat; there's hardly time for the user to get impatient and bounce.

My point about the shape of the curve stands. 100ms can matter more on the steepest part of the slope than 2s does further to the right.

> I'm curious why incrementing in a loop can be unrolled and inspected to optimize to an addition, but doubling the number when both operands are equal can’t?

I expect because the former helps more in optimising real-world code than the latter. It’s not worth the LLVM developer's time to make the compiler better for programs that it won’t see in practice.

It’s not as if the compiler did nothing with that code, though. It replaced the multiplication by a left shift and removed the branch.

It's a marketing page primarily intended for a non-technical audience who probably don't know (or care) about the differences between Open Source and "the source is open".

Flagging the post for "false advertising" is complete overkill. It's also inaccurate, as at no point does the page claim Fizzy complies with the Open Source Definition.

If it helps, DHH has acknowledged this distinction elsewhere:

> This is done under the O'Saasy License, which is basically the do-whatever-you-want-just-don't-sue MIT License, but with a carve-out that reserves the commercialization rights to run Fizzy as SaaS for us as the creators. That means it's not technically Open Source™, but the source sure is open, and you can find it on our public GitHub repository.

Look, I have my political views, but this is why the whole divide and conquer thing is 100% true. As long as we, whether left or right, allow our entire mind and emotions to be warped and subverted by those in power, we will never effect change and unite against this kind of corruption, which none of us stand for.

It doesn't require us to change our views on areas where we don't agree. It simply requires uniting on the numerous areas where there is common ground.

I don't know about you, but I'm tired of this.

Your average Joe does this and gets ripped away from his family for 10-years. Politicians do it and it gives them job security.

The two-party system amounts to two wings on the same bird. While we're fighting about left vs. right, we're soon going to find ourselves in a new system of lords vs. peasants.

It's somewhat hard to say for sure right? Most people don't post a blog post when they themselves brick their computer.

Having said that, a PleaseDontDoAnythingStupidEval would probably slow down agentic coding quite a bit and make it less effective given how reliant agents are on making and recovering from mistakes. The solution is probably sandboxes and permission controls to not let them do something overly stupid, no different from an intern.

Silly comment. Handwriting is proven to be correlated with much better memory retention, which ultimately means much greater degree of association with existing memories and the creation of novel ideas.

"The comparison between handwriting and typing reveals important differences in their neural and cognitive impacts. Handwriting activates a broader network of brain regions involved in motor, sensory, and cognitive processing, contributing to deeper learning, enhanced memory retention, and more effective engagement with written material. Typing, while more efficient and automated, engages fewer neural circuits, resulting in more passive cognitive engagement. These findings suggest that despite the advantages of typing in terms of speed and convenience, handwriting remains an important tool for learning and memory retention, particularly in educational contexts."

https://pmc.ncbi.nlm.nih.gov/articles/PMC11943480/

You are literally handicapping yourself by not thinking with pen and paper, or keeping paper notes.

The future is handwriting with painless digitization for searchability, until we invent a better input device for text that leverages our motor-memory facilities in the brain.

> I do like your idea of putting solar panels on a car to run the aircon

I thought you were talking about air conditioning in buildings. In warm climates, in a car, cooling is usually free: roll down your window and catch something called a "breeze". Works great unless you're on the freeway. But if everyone moved to a warm climate, as you, suggested we'd be living way more dense so you'd drive way less anyway. checkmate

There are also these things called "electric vehicles" that you can charge with solar power without requiring a panel on the vehicle.

I've heard people working in construction industry mentioning that quality of design fell off the cliff when industry began to use computers more widely – less time and less people involved. The same is true about printing – there was much more time and people in the loop before computers. My grandmother worked with linotype machine printing newspapers. They were really good at catching and fixing grammar errors, sometimes catching even factual errors etc.
