Get rid of street parking so drivers can't free load on the commons either, make parking something that you have to buy (with your rent or on your own) because it actually costs something.

Also, you no longer have to worry about kids appearing into the street between parked cars that obscure their presence even near crosswalks (that cars park way too close to because they can't find parking elsewhere). Win-win.

I'm not sure how realistic it is to expect AIs to get detailed hands-on domain knowledge. A lot of this stuff humans learn by doing and by experience. AI models don't learn anything by doing and experience. A model vendor can't possibly encode all that experience into their training data, and even if they try, the problem is a lot of it will be vertical-specific, country/region-specific, and it is forever changing. SaaS firms have professional services and sales consulting teams who are constantly talking to customers about their actual business problems, and they feed that accumulated wisdom back to product management and data science, who in turn help engineering encode it into the product.

From what I've personally seen in SaaS AI agent development – if you try to build an AI agent to give customers advice in a particular business domain, you need to do a huge amount of work validating the answer quality with actual domain experts, and adjusting the prompts / RAG documents / tool design / etc to make sure it is giving genuinely useful advice. It is really easy to build a system which generates output which sounds superficially good, but an actual domain expert will consider wrong or worthless.

Who is the target audience of this? Solo devs? VC backed startups looking to move fast? Corporate teams?

> Deploy backends without the hassle

followed by:

> It is built primarily on AWS Lambda...

In my experience Lambda is absolutely a hassle.

If we are locking ourselves in to AWS products How does this improve over first-party AWS offerings like Amplify?

Also the readme... I have to try hard not to dismiss a project like this out if hand when I see the LLM generated README.md. They all look the same, have no personality, and frankly are easy to just scroll past.

If you don't take the time to curate and polish your project's readme (the absolute very first thing people read about your project), I can't help but wonder if you bothered to review and polish the code itself.

Just sounds absolutely miserable to prioritize that way of living that is so car dependent. So many negatives come from it:

- pollution

- traffic deaths

- heat generation from all the infra

- inefficient use of space

- ugly aesthetic of strip malls and parking lots

It doesn't have to be this way. We can do better to build diverse housing in our cities, leverage space at the ground level for businesses, invest in our transit to make it safer and more convenient.

Instead we just go with what's easy and continue to build roads and sprawl.

Just discovered RobyGraph - a strategy game where you code AI agents in TypeScript to navigate a graph of interconnected planets. Your robot needs to claim nodes, manage paint resources, and capture "checkpoints" (clusters of planets) to win.
What makes it interesting:
- Turn-based simultaneous execution
- Graph algorithms (pathfinding, territory control)
- Resource management (limited paint supply)
- Built on yFiles graph visualization SDK
- Runs entirely in browser (yFiles Playground)
Current leaderboard has Claude AI at #1 (720 wins), with several other agents competing. You can submit your own and see how it ranks.
The "gentle strategy" theme is wholesome - no violence, just cosmic robots painting planets

This matches my "ideal" way of writing software, which is something close to "reverse waterfall". Start with the non-negotiable truths at the lowest level, then work your way up towards the goal, which is sufficiently defined. As you go, the patterns became apparent, collapsing into nice abstractions.

The code always ends up nice and clean and modular. And, since I'm working towards the idea, I can say "here are the modular pieces I have to work with, dictated the fundamentals beneath, how do I use them to accomplish the task?". When working from the idea, I think it's easier to want to write something to achieve the immediate task, in a "not see the forest for the trees" kind of way (abstractions are about the goal, rather than the reality under). Of course, both directions are required, but I get the best "separation of concerns" going in reverse.

>How's this any different than going around and filling out fake credit applications to stop "uninvited data collection" by banks/credit bureaus or whatever?

It's so different that it can't even be compared. There's nothing similar there.

>>The intent is convenience and privacy, not fraud.

> You're still harming the business, so my guess would be something like tortious interference.

No, you're not harming the business. You're simply not following the business idea of the "business". Anyone can have a business idea of some type. Not a single person on earth has any obligation to fulfill that business idea. But somehow some people believe the opposite.

>>Point it a SharePoint/OneDrive location, a handful of excel spreadsheets and pdfs/word docs and tell it to make a PowerPoint presentation based on that information. It cannot do this. It will spit out nonsense. You have to hold it by the hand tell it everything to do step by step to the point that making the PowerPoint presentation yourself is significantly faster because you don’t have to type out a bunch of prompts and edit it’s garbage output.

Everyone I know who use AI day-to-day is just using Copilot to mostly do things like add a transition animation to a Powerpoint slide or format a word document to look nice. The only problem these LLM products seem to solve is giving normal people a easy way to interact with terrible software processes and GUIs. And better solution to that problem would be for developers to actually observe how the average use interacts with both a computer and their program in particular.

Not to rain on the parade, but this app feels to me ... unpolished. Some of the options in the demo feels less thought out and just put together.

I will try it out, but is this just me, or product/UX side of recent OpenAI products are sort of ... skipped over? It is good that agents help ship software quickly, but please no half-baked stuff like Altas 2.0 again ...

I hate that. “Bug fixes and improvements” every time. And then there are the ones who think they’re being cute with “our bird Fernando has been hard ar work eating those nasty bugs and flying over the rainbow to bring you an ever delightful experience”. Just, no. I don’t mind you flexing some creative writing muscles in your release notes if you provide actual clear information, but if you’re going to say nothing like everyone else, might as well use the same standard useless message so I can dismiss it quick.

and specifically, the big companies, in a way that people notice. Claude Artifacts, AI Studio, etc. all kinda suck. If you have used Manus or connected your own CF, GCP, AWS, etc. you see how easy it could be if one of the big guys wanted it to be (or could get out of their own way).

the big boys probably don't want people who don't know sec deploying on their infra lol.

> The UK’s National Physical Laboratory’s data shows the system being tested and used by UK police to search their databases returns the correct identity in 99% of cases. This accuracy level is achieved by balancing high true identification rates with low false positive rates.

1% is accurate when you are imagining a one-off identification, like a police line-up. But when you are conducting millions of scans a day that means you are triggering tens of thousands of incorrect identifications per day (assuming equal type i/ii errors). Many of those are going to be identifying an innocent person as a wanted suspect, or pinning people as being near a crime who weren't actually anywhere near, or identifying a lawful immigrant as someone that overstayed a visa etc etc.

I consider a lot of my cleverness when writing code is aimed at achieving functionality, performance, conciseness, etc., while being easy to understand and self-debugged by design. The latter meaning:

• Types enforce safety

• Very tight dependencies

• A tight design (value, store, control flows) where most bugs are likely to be catastrophic, or at least highly visible, as apposed to silent. It works, or it doesn't.

That seems so basic to writing the "most cleverest" code, that the quote makes little sense to me.

I spend a very small percentage of my time debugging, outside of the real-time development-time write, run, correct loop. If that ever took a significant fraction of time, it would give me some serious anxiety.

Some Rust proponents, but certainly it's obvious not all of them, or not even a meaningful majority.

Which is to say this despicable act has absolutely no bearing on the language and its ecosystem, so bringing it up is irrelevant, and therefore those downplaying it are not necessarily in favor of the act.

I hope that logic is self-evident.
Show HN: aither.computer – ML tooling for mere mortals
by hyperprior | 2026-02-02 20:44:36+00:00
here's the problem: ml tooling is built for ml engineers.

that sounds obvious, but think about what it means. every model tracking tool, every experiment logger, every serving platform assumes you have dedicated infrastructure people. that you know what mlflow is and have opinions about it. that you've read papers on model drift.

most teams building with ml don't have that. they have a model that works. they want to ship it. they want to know if it breaks.

the PhD tax
right now, if you want to do ml "the right way," you pay a tax. you either:

hire someone who knows the ecosystem
spend weeks learning tools built for different problems
skip observability entirely and hope for the best
option 3 is what most people choose. not because they don't care, but because the alternatives cost too much.

we think that's wrong.

what we're building
aither is ml observability for the rest of us.

track your models. understand their predictions. serve them. log everything. no phd required.

the goal is stripe-level simplicity. you shouldn't need to understand our architecture. you should be able to add three lines of code and see what your model is doing.

Efficiencies and effects are at the point where taking a photon, converting it into an electron, and using that electron to pump heat is more efficient than turning that photon perfectly into kinetic energy.

Similarly, in mild weather, it is more efficient to burn hydrocarbons and turn it into electricity to run a heat pump than use that hydrocarbon for it's heat energy directly.

Pumping heat is more efficient than making it.

Cadmium is only required in cadmium telluride solar panels, which have less than 5% global market share. Lead solder is still common in crystalline silicon panels, though not universal; modules built with heterojunction cells typically avoid solder because the cells can't tolerate temperatures that high:

Interesting article. I find it a little bit ironic, though, to say "it's more complicated than just a one dimension", and then to use what sounds like "naive metrics" to e.g. compare democracies.

Isn't it arbitrary to say "the longest standing"? What about "the oldest"? Would Greece qualify? Or "the happiest"? Or "the less unequal"? There are surely many ways to compare democracies.

> Events are pro-democratic [...] such as free and fair elections with multiple parties, and courts and parliaments;

Apart from being the "longest standing" democracy, could one ask if it is the most exemplary? Shouldn't that count as well? There are only two parties in the US, and they don't exactly cover the largest spectrum of political opinions. For many other countries, the US don't have a "left" at all: in comparison they would be the right (democrats) and the far right (republicans).

> or if they are in support of civil liberties such as freedom of association and speech.

Same thing here: "freedom of speech" is more complicated than it seems. Does being in support of hate speech count as pro-democratic? One could ask... When Elon Musk, after making nazi salutes himself, says that Germany is against free speech because it is illegal to make a nazi salute there, does that count as pro-democracy?

(I didn't read the article but the headline said "C++" and it did not say asm {...}, so here is a brief description of what's going on)

if you want to multiply two 8 bit numbers together, worst case (biggest numbers), you need 16 bits to hold the answer.

if you want to multiply two 16 bit numbers together, you need 32 bits to hold the answer. and so on, so you need a hardware wordsize twice as big as what you are trying to do.

if you don't have 64 bits, and you decide to use 32 to mimic it, well 32's require 64's to hold the answer and we just agreed you don't have 64s, so you need to go to 16 to catch the overflow into 32 so you can piecewise handle the 16 bit halves of the 32 to mimic the 64 you are trying to pretend you have. It's really just like gradeschool multiplication on paper where you piecewise multiply and add the different pieces together appropriately.

-----

"in hardware", like inside the CPU, you can handle calculations in exactly the space you have because you have extra bit flags like "overflow" OVR and you can do shifts to handle a bit at a time, etc. or even a ton of extra bits that add up to 128 even though the results will be in 64 bit registers. at the level of C and C++ you don't have the facilities for that (a glaring omission imho, but so called smart people are dedicated to taking C even farther from being useful for what it's useful for)

Who knows, the tide might turn. 2025 was "we gotta show off our chops by having the most AI everything in all our workflows so we can put it in our press releases".

In 2026, all this stuff is commodity now. Soon investors might stop conflating "spending a ton of time and money buying the same commodity AI products as every other company trying to pimp their pressers" with actual investment in AI.

feature request? dumb question, but can you add underneath or after you click your vote and before you show it. can you ask "What do you think most people answered" for that question.

It is cool to see the distribution of yes/no. But maybe when you do that you can do a kind of....how far off was i type result that lets people learn about their...biases? or just a fun surprise.

It’s a lot faster and easier than it used to be. Things like xUnit in the .net world make setting up tests friction free to the point where I question a codebase that doesn’t have some kind of basic unit tests. It doesn’t make mock testing or integration testing easier but I would argue if you know the base code and logic is sound those tests are less relevant.

One thing I found is that if testing is easy, your code structure does change a bit to aid with a “test first” approach and I don’t hate it. I thought it made me slower but it doesn’t, it ensures that when all the ground work is finished, the gnarly part of wiring everything up goes much faster.
