I’m showing my inexperience here by stating the obvious, but acquiring users is HARD!
Is my product bad? How can I make it better?

I've been building a landing page for Glance ( https://glance-fi.app/ ) to figure out whether anyone actually wants this before I go deep on it. It's a finance app (I know — another one, stay with me here) that skips budgeting entirely, instead tracking spending and trends. It learns your spending patterns and flags anomalies — DoorDash doubled, weekly spending is above normal, a subscription you forgot about is stil…

I built a scraper that pulls every job posting from the Who's Hiring thread, runs it through DeepSeek to parse the unstructured text into a uniform schema (role, company, location, remote, salary, stack), and presents them in a searchable/filterable UI. I know tools like this exist but I couldn't find one with the filtering and UI I actually wanted, so I built it myself.
Stack: FastAPI + Next.js + PostgreSQL, containerized on AWS ECS Fargate with an ALB. Frontend on Amplify. This is honestly my first real AWS deployment and I don't ever want to do this again. ECS alone took me a solid day to figure out. I also can't get amplify to use the domain I bought even though I set all of the DNS records up :/
Email notifications are still being worked on so right now it's just a view of all the job postings. Job match notifications and saving jobs should be up soon.
I would love feedback on the job matching and UI in the meantime (especially if you find a bug). Happy to answer questions or hear how you'd approach the AWS side differently!
I'm building a manually curated catalog of videogames made by HN users. Currently I'm adding data to catch up to today's games. Check it out: https://hn-games.marcolabarile.me/ (includes games up to June 2024 atm) Feedbacks and feature requests are welcome!
https://concludia.org/ - I've mentioned it here before, it's a site to help people reason through and understand arguments together. No real business purpose for it yet, it's more an idea I've had for years and have been wanting to see it through to something actually usable. You can graphically explore arguments, track their logical sufficiency/necessity, and make counterpoints. It's different than other types of ar…
The core idea:
Treat the economy as a constrained 2D energy manifold where money is a bookkeeping layer over energy allocation, and macro structure emerges holographically from boundary-level discrete transactions.
Very roughly:
L1 — 2D Manifold Hypothesis Social/economic systems behave like low-dimensional constrained surfaces rather than high-entropy volumetric systems. This reframes growth, inflation, and inequality as curvature problems rather than equilibrium problems.
L2 — JT-Gravity Analogy Introducing a Jackiw–Teitelboim–like action to model macro constraints. Policy acts like boundary condition manipulation rather than “force injection.”
L3 — Holographic Mapping Discrete micro-transactions at the boundary construct macroeconomic structure in the bulk. This attempts to dissolve the 100-year micro vs macro divide.
L4 — Random Matrix Regime In high-complexity phases, the system transitions to random-matrix statistics (crisis, bubbles, phase shifts). Stability becomes a spectral property.
I’m currently working on:
- Formalizing the action functional (so it’s not just metaphor)
- Defining the admissible ensemble boundary for economic RMT
- Building a small simulation engine to test curvature vs liquidity stress
This is still early and probably wrong in 20 different ways. But if the geometry holds, it could provide:
- A unification layer between econ and complex systems physics
- A compression model for macro indicators
- A path toward AI-native economic modeling (neuro-symbolic)
Would love to hear from:
- Theoretical physicists willing to sanity-check the gravity mapping
- Quant folks familiar with RMT edge cases
- Anyone who thinks this is obviously nonsense
Happy to share drafts if there’s interest.
