l___l··on Ask HN: What hard problems are still underexplored?
Downvoting when someone gives information you didn't have makes them not want to give more information.

A word to the unwise is insufficient. https://www.paulgraham.com/word.html

Perpetual-ish motion machines exist if you know where to look.
l___l··on Ask HN: Should "I asked $AI, and it said" replies be forbidden in HN guidelines?
> There's zero value in these posts

Source?

You might be surprised by the tremendous amount of value in AI posts. AI considers context NI doesn't.

l___l··on Ask HN: What hard problems are still underexplored?
The problem with ambiguous boundaries, messy constraints and the perception that there is no linear path to transferring meaning in language.

That you know of.

If it was only a minor incremental innovation, in this specific form, wouldn't it have appeared years earlier?

> haven't seen a use case but crypto yet.

BTC is up 500%+ since 2 years ago. This looks like a use case to me. It maintained purchasing power better than stocks and bonds.

This comment read to me like AI slop.

> there's no way Bitcoin is more efficient

No way? You studied this personally and can prove it?

> its nothing more than a high risk stock

Nothing more? Proof-Of-Work wasn't innovative?

With fiat you have high risk of losing 50% of USD's purchasing value within 2 years, which already happened, and which is not far from being robbed, as have happened to millions of people too.

One interpretation of this comment, if viewed from an adversarial angle, is that comments like this, although perhaps not this comment specifically, are designed to dissuade people from buying crypto days before a bull-run starts.

Accurate data illuminate a lot of things.

A different metric of comparison isn't Bitcoin's energy consumption compared to other countries but compared to the existing banking system it's trying to replace, which burns more energy than Bitcoin and allegedly burns more energy funding wars with fiat. Mining gold instead of Bitcoin burns more energy than Bitcoin too.

Compared to that for energy consumption, Bitcoin is superior really.

One theory backed with proprietary data is that it's because bitcoin was created by the US government and money printed by the Fed goes in bitcoin so the government will one day pay its projected $113T of debt by dumping on everyone.
l___l··on Launch HN: Phind 3 (YC S22) – Every answer is a mini-app
I want a simple CRUD mobile app that talks to a website. Like a website where you GET and POST to read and write data. Something that copies the submission forms of a website and gives me the website as a mobile app. Something that identifies all endpoints in a website and gives me access to these endpoints as a mobile app.
l___l··on Launch HN: Phind 3 (YC S22) – Every answer is a mini-app
Without looking further into hallway, I'm inclined to say no because it doesn't instantly prompt me to describe the app I want to build.

I want to build an app. Not to enter an email in a textbox.

l___l··on Launch HN: Phind 3 (YC S22) – Every answer is a mini-app
This might be super-obvious or it might already exist but can you make Phind create mobile apps? I don't know of any site that builds a mobile app and actually gives you the app instead of give you half the app or ask to pay for credits and so on and never showing you the full real app that you can install on your phone and actually use.

Phind user for ~2 years.

l___l··on Ask HN: Would you use a fast/cheap "prior art" service instead of a patent?
How does disclosing an invention protect it? Protect it from what and for how long? If a patent isn't filed eventually then competitors can file.

Why not publish the invention on a blog?

Why not keep the invention a secret?

l___l··on Don't obsess with security and privacy unless they are your core business
I want privacy and security over everything else. This disproved your point.
l___l··on Ask HN: Vitalik says that QC might break ECC before 2028. This is crazy, right?
> Quantum computers haven't even factored a three-digit number yet, right?

Since there isn't proof that such computers don't exist, the answer is: wrong.

l___l··on Ask HN: Have you ever seen a perfect codebase?
I've seen a perfect codebase. It models the problem well, is easy to understand, and has tests for all inputs.
l___l··on Cloudflare outage on November 18, 2025 post mortem
> The software had a limit on the size of the feature file that was below its doubled size. That caused the software to fail.

What could have prevented this failure?

Cloudflare's software could have included a check that refused to generate the feature file if it's size was higher than the limit.

A testcase could have caught this.

l___l··on Show HN: What if every photo/video could prove itself?
Is the Witness a person or something else? Can the Witness be faked?

I also have the same questions I had 48 days ago:

https://news.ycombinator.com/item?id=45364282

How would fake content not be able to fake the proof?

What's to prevent fake content from generating cryptographically signed photos and videos that embed a JSON manifest with the same characteristics as this service?

l___l··on Email verification protocol
Why must apps require email? Why not only username and password?
l___l··on Show HN: I made an open-source web engine for relativistic simulations
Connect with Tor.
l___l··on Show HN: I made a md editor without the stuff that distracts me from writing
I wish there was a live demo I can use, to experience it.

I won't download it to see how it works.

I would use this if it didn't require a login or my email address.
l___l··on Show HN: From100k – a job board for IT roles starting at $100k+
Both before and after. It happened:

1. After talking to the company recruiter.

2. After the interview, not hearing anything back for more than a month.

3. Before the interview process, sending a resume and not getting back an automated email that says we got your email, or an email that says we're no longer hiring for this position, or we hired, or whatever. How am I supposed to write a cover letter that the job post suggests without knowing if the job is a ghost job that doesn't actually hire?

l___l··on Show HN: Autism Simulator
Does it ever go beyond the second day? I tried many options but it goes from energy 73 to burnout in one step.

Some of the options don't show at all, I get a blank screen. Coming from Tor.

l___l··on Show HN: From100k – a job board for IT roles starting at $100k+
I want companies to pay me when they ghost me.

Good idea!
