I'm Ben Trettel, an experienced mechanical engineer with a PhD, specializing in computational fluid dynamics, design optimization, and verification & validation of computer simulations. Also, I am knowledgeable about patent law from time spent at the USPTO as a patent examiner.

I am particularly interested in opportunities to build cutting-edge physical products where computational simulation and design optimization are key.

NoSQL was more of a convenience thing for most people during that trend. You might have some bag of attributes that maps perfectly fine onto relations, but that also doesn't help because you only ever get/set the whole struct at once. People used to use ORMs to get around that, then NoSQL became popular, and now you can just use jsonb in SQL while still maintaining relations for other things.

This doesn't say much about the horizontal scaling aspect, but not a whole lot of users really needed that.
Show HN: Ledge - Policy layer for AI agent payments (prevents unauthorized txns)
by devendra116 | 2026-03-02 16:17:35+00:00
Hey HN,

I built Ledge because I kept seeing demos of AI agents with wallet keys in their .env files, and thought "this is going to end badly."

The core idea: put a policy layer between your agent and the wallet. Before any payment executes, it runs through 4 checks (technical validation, policy limits, context coherence, behavioral patterns). Agent can pay for APIs/data autonomously, but only within rules you set.

Example: your research agent has a $10 budget. It can pay $0.01 per API call for data feeds. But if it tries to send $50 to a random address, or hits the same endpoint 100 times in a minute, Ledge blocks or escalates it.

Built for x402 (pay-per-request protocol), but designed to be modular for other payment rails. Python SDK, supports KMS/Turnkey for production.

Main questions:
- Is this solving a real problem or am I overthinking agent security?
- What policies would you want that aren't here?
- Anyone else building agents that need to pay for stuff?

GitHub: https://github.com/Devendra116/ledge

Would love feedback, especially from folks building autonomous agents or working with crypto payments.
Show HN: Local Hours – Time tracking that's just files (no accounts)
by stinger | 2026-03-02 16:17:40+00:00
Have you clocked in yet?

I built Local Hours, a simple time tracking / timesheet app that treats your data as plain files instead of rows in someone else’s database.

No accounts, no backend – All time entries and timesheets are JSON files in a folder you pick. Sync happens via iCloud / Dropbox / OneDrive if you want it.

Cross-device by design – The macOS menu bar app and iOS app both point at the same folder, so they “sync” via your storage provider without any server code.

Timesheets, not dashboards – The main job is: track time, then generate a weekly/bi-weekly/monthly timesheet you can actually send to an approver.

Exports that don’t trap you – You can send an email with an embedded summary + CSV, or just open the JSON files yourself.

Privacy – No analytics, no telemetry, no in-app purchases. It’s MIT-licensed and fully open source.

Apps are free on the App Store (iPhone, iPad, Mac):
https://apps.apple.com/us/app/local-hours-simple-timesheet/i...

Repo (code, storage format, docs, screenshots):
https://github.com/gogrinimish/LocalHours

I’d especially like feedback on:
Does the “just files” approach line up with how you’d want to archive or script your own timesheets?
Is the UX for picking the storage folder and sharing it across devices clear enough?
What’s missing for you to actually use this for client work?

This has been happening for decades.

China spends a lot of money on international Chinese education. According to some , the top schools are now Chinese.

https://www.economist.com/science-and-technology/2025/06/18/...

Honestly the best thing about America, historically has been diversity. Mei can come here and become American within a few years. That’s only possible in America( and probably Canada too).

But now we don’t want international students. The world’s smartest will go elsewhere.

One tip for the introverts out there:

When the service worker and you do the back and forth of "How are you doing today" - "Fine, you?" - "Fine"

Yeah don't do that, try out this phrase "It's my Monday" [0] instead of "Fine, you?"

You'll typically have them telling you what day of their work week they are in which is not usually the actual day of the week! Because managers schedule people in service positions in wacky ways.

That little bit of human connection around labor and work, man it does wonders. They know you know what it's like, that you see them as a person, and you care a little bit. Really gets the conversation going if there isn't too much of a line.

[0] Use any day of the week, but do use a weekday. Monday or Friday works best though.

AI Systems Architect. I build inference infrastructure, agentic pipelines, and production ML stacks — not prototypes that crumble in prod.

Track record:
- Employee #1 at Refact.ai (ex-OpenAI founder). Scraped 80M code repos, co-built dataset for Refact-1.6B-fim (SOTA HumanEval 2022). Built enterprise LLM inference backend, RAG over AST+vectors, SWE-bench-compatible agent loop.
- Interim Head of AI (0→1): shipped full air-gapped ML stack in <6 months — training, inference, synthetic data pipelines, fine-tuned BERTs/LoRAs at 70 labels production F1.
- Currently: sub-400ms voice-to-voice cascade (STT+VAD+LLM+TTS) on consumer GPU. Zero-dependency MCP server in pure Python.

I operate as Nautiloid Protocol LLC. Clean B2B engagement, no hiring overhead, no equity games.

Looking for: AI infrastructure contracts where output is judged by systems shipped, not meetings attended.

You’re the first comment as I scrolled challenging the premise. But your solution amplifies what I see as a problem.

I’d like to add, that by forcing myself to look up the answer every time I have happy accidents where I learn new ways to do things.

It’s a skill to be willing to unlearn and always presume yourself ignorant, even if you do know how to do it. It’s like confirming “is my way still best practice.”

There has been a lot of research into discovering new physics (starting by discovering old physics) since the last 5-6 years and it always require:

- A lot of high-quality data
- Some careful design
- (Not always) some external knowledge to guide the solutions

And this is using specialized NNs for physics, where you often know underlying equations. Kind of crazy that some people are so delusional about that.

> Give me a break. People on /r/datahoarders pirate millions of books all the time. Use a VPN and basically nobody bothers going after you. If anything Meta/OpenAI are getting harsher treatment than the average person because they're juicier defendants.

Arguing that a regular person needs to conceal their real identity with a VPN to pirate books is proof these companies aren't receiving special treatment for committing the same crimes is very confusing to me.

We know the identity of the companies committing the crimes.

A different perspective. I'm a first generation immigrant that moved from Russia -> US 30 years ago with my parents.

Some things to consider:

Despite living here for 30 years, my parents don't feel they fit in. Their friends are Russian and the media they consume is in Russian. At the same time, they wouldn't fit in back in Russia either at this point. It's a weird state where you lack a strong cultural association. If you move, highly recommend immersing yourself in local culture, language, and activities.

We moved here because my dad had a good job at an international company (software dev). Our immigrant friends who are doing well are in a similar boat, or have entered higher paying fields like nursing. If you don't plan to climb the financial ladder via upskilling, or aren't in a transferrable career, your material life will be much better in your home country.

Overall, I don't think their quality of life changed much between the two countries. They are educated, white collar workers who would have a similar life anywhere they lived.

Not sure why you're getting downvoted but yes, this is true.

I don't want or need to talk to everyone, and I generally don't appreciate people I don't know or won't know in five minutes to engage me in idle chatter. Just leave me be.

I'm not a grouch, I'm not a grump, I'll be friendly but why do you have to harass me?

I'm perfectly comfortable in my own skin, doing my own thing, by myself. I don't have social anxiety, I'm not a misanthrope. Just let me be.

> Once that gets filled up, it’s pretty much impossible to understand where the giant block of memory is.

Your friend is called ncdu and can be used as follows:

sudo ncdu -x -e --exclude Volumes /System/Volumes/Data/

The exclude for Volumes is necessary because otherwise ncdu ends up in an infinite loop - "/Volumes/Macintosh\ HD/Volumes/" can be repeated ad nauseam and ncdu's -x flag doesn't catch that for whatever reason.

I'm an early adopter. I genuinely enjoy exploring new ideas and trying early-stage products.
But lately, when I browse launch platforms, even SideProject subreddit, it feels like almost everything is behind a paywall. Some offer a free trial, but I more often see posts saying something was vibe-coded in a few hours, and yet it costs over $50 to use. What feel odd to me is this: They are asking people for feedback. But if People can't actually use the product without paying, how people supposed to give you meaningful feedback? Is this just promoting subscriptions or asking feedback? I've seen builders ask for feedback while the core funtionality is locked unless you subscribe. That feels COUNTERPRODUCTIVE.

I understand that if you're running something expensive in the backend, like LLM API, costs add up quickly. In those cases, limiting or charging makes a bit sense. (but I still early-staging product should provide full service to get more feedback, even it spends some money from builder) But for products without significant marginal costs, does it really make sense to monetize immediately?

In business school, I was taught that early on, you should focus on growing the pie. Build users. Build trust. Now that integrating Stripe takes five minutes, it feels like some builders are obsessing over revenue before they've validated value.

Maybe I'm wrong. Maybe early monetization has become the dominant trend for a reason.

I'm just curious how others think about this.

Sometimes I reflect on all the metaphorical forests that have burned because a certain person at the right time only knew so much about how to use Excel, or the inbox rules of their MUA, or being totally unaware of the incredible power of macros of all sorts.

Like if you could just sit someone down for 30 minutes and show a few "power user" things, you will have truly taught her to fish for a lifetime. But it can go so unaddressed, and people's careers are built on these small ignorances.

I've cancelled everything at this point and just call Emacs my "special agential assistant," it makes me still sound in-the-know, and most of the time no one knows the difference!

"Convenience" in this context is laziness; "productivity" and "efficiency" is for management and bosses. We don't need to be our own bosses, I want to be free from such things as an individual. I want to be capable, be maybe almost "cool." Its sad to see a whole generation turn into such product dorks!

Humans also write endless amounts of convincing bullshit, and have done since time immemorial. False papers and faked results have been a growing scourge in academia before LLMs were a thing, and that's just counting the intentional fraud - the reproducibility crisis in science, especially medical and psychological science, affects even the best designed and well intentioned of studies.

Humans also make mistakes and assumptions while reverse engineering, so it will always need more engineers to go through the results, test things

Hi HN,

I posted this a few days ago and got some quiet but positive interest. I've spent the weekend hardening the "Sovereign" aspects of the app.

The Architecture:

React 19 + Vite: Using the latest React features for a high-performance IDE feel.

Immutable Ledger: Every transaction is a state transition in a double-entry system. No "editing" history—only reversals and corrections, just like real accounting.

Local-First (IndexedDB/LocalStorage): Your financial data never touches my server. The app is a static client.

Stateless AI Proxy: We use Gemini to parse "Paid $50 for AWS" into structured journal entries, but the proxy is stateless—it doesn't store the prompt or the result.

Why?

I wanted a tool where I could work on my runway in a coffee shop without worrying about the person behind me (hence the Privacy Shield blur mode) or my data being sold to advertisers.

I'm auvira_systems and I'd love to discuss the trade-offs of building complex stateful apps entirely in the browser.

> Agree with you on the foldables. God, no one wants that.

I think there are a lot of people who would love to have a smaller form-factor for when the phone is in their pocket, with a large screen for when it's being used. The current state-of-the-art might not be very good for foldable phones, but the demand is there, and that's what drives innovation.

I just cannot for the life of me understand the problem that this is solving. The only way that makes any sense is if sessions are atomic along with commits. If a session results in many commits in this becomes a fundamentally incomplete record, such as it was a record at all. Even if we do restrict to one session per commit, we are not in control over the agent’s context—-the session details will contain the user prompting the actions and the reasoning summaries. It will not contain a crucial part, which is how the agent assembles information about the project. So you’re left with a record that looks very complete and is silently incomplete. I don’t understand what the benefit of retaining that is.

There are people who do not want to have abortions. Either for religious reasons, because they themselves belong to a specific disability group (e.g. the blind and deaf) or because they tried hard already to get pregnant in the first place.

Especially for the latter, "make a new one" can mean a ticket reaching into the 6 figures, months of egg extractions, implantation attempts and spontaneous auto-abortions.

As a frequenter of Lemmy (and I suppose PieFed because it's federated), it's really the opposite of HN culturally for better and worse. The only thing that feels the same is that most Lemmy users only look at the "All" feed so it basically becomes one feed like here on HN. I haven't browsed Reddit since the API issue, but I remember it being a lot more usable in the way GP suggests, i.e. subscribing to individual communities to engage with. I've found the SNR on Lemmy to also be poor for quite a few reasons, so if you're right about Reddit's being worse then I have to wonder how it's still as popular as it is.

Fun fact, some plant like Bulgur or Lentil are almost as calorie dense as some meat. But to my understanding, they lack “complex” protein or something ? Regardless, your don't have to cut meat entirely. The issue is that we consuming way too much of it. In many developed country, eating meat every day is very common. Eating meat once or twice a week is enough to get all the right nutrient and not having deficiency in things like B12.

This reminds me of when people say “I can’t believe developers use VS Code, real developers use vim/emacs”

It’s a tool, a means to an end. I just want my tool to be easy to use and work.

Another analogy would be cars: do you tune and modify, or do you want a transportation appliance?

There is no wrong answer. Maybe your hobby is tinkering with your tools. If that’s you, more power to you.

I want a phone, editor, and car that are easy to use and “just work.”
Show HN: Free Browser-Based Tools Client Side Only, No Uploads, No Tracking
by axyz7732 | 2026-03-02 16:21:07+00:00
I got tired of juggling 20+ tabs for basic utilities (JSON formatting, PDF merging, regex testing, image resizing, fake document generators, etc.), so I built a single, fully client-side hub with over 200 tools that run entirely in the browser.
Key points:

Everything processes locally—no server uploads, no data leaves your device, no sign-ups, no ads, no tracking.
Works offline after the initial load (progressive web app vibes).
Categories include: Developer Tools (JSON/YAML/CSV/Regex/Base64/Epoch/etc.), PDF Tools (merge/split/compress/convert/extract), Image Tools (resize/compress/watermark remover/background remover/OCR), Encoding & Security, SEO & Network utilities, AI-assisted tools (e.g., ATS resume checker/roaster), Finance calculators (GST/salary/tax), Document & Fake Generators (resumes/invoices/fake chats/tickets/etc.), and more niche ones.

Built with plain HTML/JS/Canvas/WebAssembly where needed—lightweight, fast, mobile-friendly.
Live here: https://tools.geeksprep.com/
Why share now:

Started as a personal productivity fix for devs/designers/job seekers in India (Bengaluru-based side project).
Grew to 200+ tools via user requests and iterative additions.
Privacy angle is core: In a world of upload-heavy "free" tools, this keeps your data yours.

Would love honest feedback from HN:

Which tools are actually useful (or broken)?
Missing must-haves in dev/productivity space?
Performance/edge cases on large files or specific browsers?
Suggestions for better UX or new categories?

It's open for iteration—happy to add/fix based on real input. Thanks for checking it out!
(Part of the broader GeeksPrep career prep platform, but this tools subdomain is 100% free/independent.)
