Hi HN, Lytok 2.0 is officially out. It’s designed to be a lightweight and efficient way to handle data structures in web environments.

You can play with it in our interactive lab or integrate it directly into your project: npm i @lytok/js

Feedback is more than welcome!

While solving a Skewb[https://en.wikipedia.org/wiki/Skewb] cube I thought it would be interesting to have the subproblems of it presented as puzzle games, one thing lead to another and here is the result.

I have definitely some UX problems so looking for feedbacks and thoughts.

The best part of this game is, level generation and difficulty analysis can be automated. I have here 15 tested and 5 experimental levels.

I enjoy 15th level the most, has an intuitive solution.

You can try the competitive mode with a friend, you need to share the link with them.

If I can bring the level count to thousands, I will add a ranking system.

My mind keep racing about the possibilities, but kind of cannot prioritize at the moment.

All kind of feedback, collaboration requests are welcome!

Hello everyone,

I hope you’re all doing well.

I’m reaching out to ask for guidance regarding a crypto recovery situation my family and I are currently facing. We are exploring the possibility of using digital asset forensics to help trace and recover crypto funds that were unfortunately lost/transferred under unclear circumstances.

A few specifics:

The transactions were made on Ethereum/Binance Smart Chain (or insert relevant chains)

We do have the wallet addresses and transaction history

We do not have direct access to the private keys

We are not entirely sure where the funds ended up

Before committing to any service, I wanted to gather insights from this community on:

What reputable digital asset forensics providers are trusted by members here?

Any recommendations on what documentation they usually require?

What red flags to watch out for in crypto recovery services?

Realistic expectations on timeline and success rates?

I’m aware that recovery isn’t guaranteed, but I want to ensure I pursue this in the most informed and safe way possible, avoiding scammers and false promises.

Any feedback, experience, or resources you can share would be greatly appreciated.

Thank you!

Built an offline encryption tool for people who don't trust cloud services or hardware wallets.

Paranoid Qrypto runs completely offline (air-gapped). You type your seed phrase on an offline device, and it encrypts it using Argon2id + AES-256-GCM. The encrypted file can be stored anywhere USB, cloud, printed as QR code without exposing your keys.

Why this was build: Hardware wallets cost $100-200 and are single points of failure * Cloud solutions require trusting a third party * Paper backups have no protection if found

Technical details: * Runs in browser with no server calls * All encryption happens locally * Open source tools on GitHub: integrity-auditor, airgap-bridges (BTC/ETH/XRP) * Three tiers: Essential ($99), Advanced ($199), Ultimate ($299)

Happy to answer questions.

Cisco has donated its Project CodeGuard to the Coalition for Secure AI, an open-source initiative aimed at developing secure and trustworthy AI systems. The donation will help expand the Coalition's efforts to address security and safety challenges in AI development and deployment.

Scientists warn that age verification on social media platforms is an ineffective and privacy-intrusive approach to protecting minors online. They argue that a more holistic, evidence-based approach that focuses on digital literacy and responsible platform design is needed to address the complex challenges of child safety in the digital age.

I shipped my first product yesterday after years of not finishing anything

I'll be honest — I've been wanting to build something of my own for years. I'm a senior manager in analytics, and I've never shipped a single side project.

Yesterday I sat down and didn't get up until something was live. I built a CSV analyzer — you upload a CSV file and it instantly gives you statistics, interactive charts, and AI-powered insights that explain your data in plain English.

Stack: Next.js, Anthropic API, Stripe, Vercel.

Pricing: Free for files under 500 rows. $2.99 one-time for a single AI analysis. $9/mo for unlimited.

It's not perfect. But it's live and that's a first for me.

I'd love feedback from this community. What's missing? What would you change about the pricing? How did you get your first users?

Hi HN — I built something that’s been genuinely useful for myself and other Garden Horizons players, and I’d love to get feedback.

Website: https://gardenhorizonscalculator.co/

Garden Horizons (a popular Roblox farming game) has a deceptively complex economy — crops have weight-scaled pricing, ripening multipliers, color variants, and mutation effects from weather. Figuring out the actual sell value of a harvest has historically required spreadsheets or manual math to estimate.

What I needed was a tool to instantly compute the sell value and profit for any crop setup before I actually sell, so I built one.

What it does

Takes crop type, weight, ripeness state, variant, and weather mutation data

Calculates exact sell price in Shillings

Helps optimize when to harvest and which crops to plant for best profit

Runs entirely in the browser — no sign-ups, no tracking

The goal was not just a lookup chart, but an interactive calculator that helps you compare scenarios quickly without manual spreadsheets.

Looking for feedback

I’m curious about:

Whether others find this useful

Any edge cases I haven’t covered

Suggestions for UI or expanded functionality

Happy to answer questions. Thanks!

The article explores the fascinating history and global impact of sugar, tracing its emergence as a valuable commodity and its role in shaping world events and economies over centuries. It delves into the complex interconnections between sugar production, trade, and social dynamics that have influenced the course of human civilization.

The article discusses the public's relatively calm response to the rapid advancements in AI technology. It suggests that the lack of fear or challenge felt towards AI may be due to the gradual nature of its progress and the perception that it is not yet a threat to human existence.

Earlier there was a mass flagging of codex sessions suddenly and many people reported teh following error message:

    stream disconnected before completion: This user's access to gpt-5.4-ab-arm3-840-1p-codexswic-ev3 has been temporarily limited for potentially suspicious activity related to cybersecurity. Learn more about our safety mitigations

Interesting that we are skipping GPT-5.3 vanilla altogether if 5.4 ships for all variants

The article discusses the technical details of the electrical components and systems used in a weather buoy, including the power source, battery management, and data transmission.

I made a public leaderboard for all time GitHub commit contributions.

https://ghcommits.com

You can connect your GitHub account and see where you rank by total commit contributions.

It uses GitHub’s contribution data through GraphQL, so it is based on GitHub’s counting rules rather than raw git history. Private contributions can be included. Organization contributions only count if you grant org access during auth.

There is also a public read only API.

https://ghcommits.com/api

The main thing I learned building it is that commit counting sounds straightforward until you try to match how GitHub actually attributes contributions.

I’d be interested in feedback on whether commit contributions are the right ranking metric, and whether I should also support other contribution types.

Konform Browser

Some highlights last time:

- Rebased on latest ESR release (obviously) - Been porting over relevant security-motivated changes from Tor Browser[0] and Mozilla. - Significantly improved fingerprinting situation making anonymity less of a pipe-dream - Addons no longer leaking their local IDs in HTTP headers - ML/"AI" features adapted for local/offline use when enabled (while proprietary cloud snoopies fully removed)

Been quiet on HN previously so keeping this submission brief. Release notes are probably the best resource right now to get an overview and feel for the project. Happy to talk more if anyone has any questions!

Would also love to hear feedback from anyone who's either tried it out or dug into the repo.

[0]: Big thanks and cred to inspiring maintainers and contributors there
