I built a 3D website for my music using React Three Fiber, where the album covers float in space as clickable 3D cd covers that open when the details for a release are shown. The website also supports keyboard navigation, and tracks can be previewed in low quality (the logo also is a metronome while music is playing). I would love feedback especially if you have any ideas on how to improve the performance and accessibility.

In physics, stress tensors generate curvature or potential fields (e.g. elasticity theory, gravitation, Poisson-type equations).

A very generic form is something like:

∇²φ = −∇·T

where T is a rank-2 stress tensor and φ a scalar potential.

This formalism is usually tied to physical matter, but mathematically it seems much more general.

My question is deliberately narrow:

Is there any mathematical obstruction to applying a stress–potential formulation to non-physical abstract systems? For example: reasoning systems, information flow, symbolic dynamics, or other structured processes. Are there known cases where such formulations provably fail outside physics?

I’m not claiming this should work, only asking whether the restriction to physical systems is necessary, or mostly historical.

Pointers to counterexamples, prior work, or reasons this is ill-posed are very welcome.

Even if ads are limited at first, this raises questions about UX, privacy, and long-term direction.

1.What do you think:

2.Would ads change how you use ChatGPT?

Are ads inevitable for consumer AI?

3.What would an acceptable implementation look like?

I left my job that I got straight out of college few months ago. Why? The main reason was I had conflict with teammate in standup meeting. Used foul words. I later apologized in front of my entire teammates and settled it down. But still I resigned later on because I felt being let go. For example: My department was changed and later I was deemed unfit for that department as I could not learn “what they wanted” in two weeks. So my manager (first department) would tell me “Since you are unfit for this role, how do we take you back?” He did take us back but promoted juniors and kept me in the first level support.

To be honest I did not like that job due to the following reasons (since the start)

The work was menial.

The pay was horrible.

The blame was most because we were the lowest hanging fruits in entire company.

I wanted to prepare for government computer engineer job.

I could not see myself in that role for long.

But the reality was I could not get crack any other private sector jobs in those two plus years. I landed couple of interviews but could not get through interviews. That was when I decided government would be a better fit for my nature.

If I keep the gap visible in my resume, I will receive many questions(I might not be screened at all to be honest).

Why could not you seek a different job instead while having your existing job?

Why could not you seek a different department in your previous company itself?

I was preparing for government job since I left my job.

So I am looking for ideas to cover that gap.

My morning routine for the last few years has been to open my 54 "Daily"-bookmarked sites in Chrome and click through them all. That's how I avoid scrolling the rest of the time. But many of those sites don't update daily, so I just click quickly through those, scanning for changes. So why not write a script to do that? That's `daily-web`. Easy install, zero config -- just import from a folder of your Chrome bookmarks. Then run it to open a new window with the changed sites. (Full disclosure: vibe-coded with Claude Opus 4.5 in an hour, while I ate breakfast. The era of bespoke personalized software is upon us.)

The PR Description Guard is a Chrome extension that helps developers protect their pull request descriptions from unauthorized changes. It automatically generates a unique hash for the PR description and checks it on subsequent updates, preventing any unwanted modifications.

I built this after struggling to find relevant grants and fellowships myself.

The project started at the EF Hackathon as a credit underwriting and matching agent for founders. After speaking with founders and students, it became clear that discovery itself was the bigger problem. Most people do not know what grants or non-dilutive options exist for them.

So I iterated and built 21st.fund.

You describe who you are and what you are building, and the tool surfaces relevant grants, fellowships, and programs. The goal is to reduce time spent digging through scattered government sites, PDFs, and outdated blog posts.

The site is live at [https://21st.fund](https://21st.fund)

It is early and incomplete, but already usable. I am especially interested in feedback on:

* Result quality and relevance * Missing grant sources or geographies * Whether this is useful before paying consultants or advisors

We’ve been working on a reusable insulin patch pump for the past year, and I wanted to share some of the engineering lessons learned so far. Insulin micro-dosing is mechanically non-trivial: basal delivery can be fractions of a unit per hour, boluses involve larger step changes, and everything has to stay within ISO tolerances while attached to a moving human body for several days.

Some interesting constraints we ran into:

- dose accuracy limits from ISO 11608 (both basal and bolus) - fluidic compliance and variable back-pressure under skin - reservoir deformation and head-pressure drift over time - motor torque margins at low battery voltages - thermal variation (skin vs ambient) affecting fluid and mechanics - occlusion detection without continuous pressure sensing

It’s one of those devices that looks like simple consumer hardware from the outside, but internally mixes fluidics, precision mechanics, biocompatible materials, power constraints, and regulatory requirements.

Happy to share more details in the comments about actuator choices, reservoirs, failure modes, materials, test rigs, or regulatory constraints.

Hi HN,

I built StayUp, a small desktop app that helps reduce friction when working with activity-based time tracking tools like HubStaff or Time Doctor.

Context: Some teams evaluate productivity mainly through “activity percentage” (mouse/keyboard events per time window). During onboarding or deep-focus work (reading docs, reviewing legacy code, meetings), this can force unnecessary interaction with the OS and hurt real productivity.

What StayUp does • Simulates minimal mouse movement, scrolling, and simple key presses • Runs fully in the background (no tray, no UI) • Controlled via global hotkeys (start / stop / exit) • Behavior is configured remotely via a web dashboard • Token-based auth with subscription & trial

Technical notes: • Desktop client requests configuration from the server on startup • Server validates subscription and returns action intervals & rules • One active device per token • Client sends only token, build number, and hashed device ID

Project page: https://stayup.xyz

I’m interested in feedback on: • Product positioning • Ethical concerns / misuse risks • Better ways to measure productivity without activity heuristics

Happy to answer questions. Thanks for reading.
