Show HN: AegisMind Discover – cross-domain hypothesis generation from papers

Hacker News - Tue, 02/24/2026 - 3:14am

I built a system that reads research papers across unrelated domains and tries to surface hypotheses that neither field would have generated on its own. The Discover page is where it publishes findings: https://aegismind.app/discoveries It's very early — only three discoveries so far — but the core idea is what I want feedback on. The problem it's trying to solve: Science is siloed. A breakthrough in mycology might have direct implications for network routing. A discovery in chronobiology might reframe how we think about database consistency. Nobody reads across all of it, and even when they do, the connection is usually accidental. How it works:

The autonomous "Right Brain" service ingests papers across domains continuously Multiple models (GPT, Claude, Gemini, Mistral, Grok) analyze papers in parallel A synthesis layer looks for structural or mechanistic similarities across domain boundaries Hypotheses are only published when they pass a novelty and coherence threshold — it won't surface things either field already knows

What I'm genuinely uncertain about and want feedback on:

How do you evaluate whether a cross-domain hypothesis is actually interesting vs. superficially pattern-matched? This is the hardest part of the novelty filter. Which domain combinations would you most want to see? (We're currently not curating this — it's whatever the system finds structurally similar.) Should findings link directly to the source papers?

Only three discoveries published so far, so the page is sparse — but I'd rather share the idea early than wait until it looks polished.

Show HN: ImgPakt – Client-side image compressor, nothing leaves the browser

Hacker News - Tue, 02/24/2026 - 3:11am

Hey HN,

I built ImgPakt because every image compressor I found uploads files to a server. TinyPNG, Compressor.io, iLoveIMG — they all require sending your images over the internet.

ImgPakt compresses images entirely in the browser using Canvas API and Web Workers. There's no fetch(), no XMLHttpRequest, no upload endpoint in the code. Files literally cannot leave your device.

Technical details: - FileReader → offscreen Canvas → toBlob() at target quality - Web Workers keep the UI thread free during batch processing - Supports JPEG, PNG, WebP, AVIF - 5 preset quality profiles instead of a manual slider

Free tier: 5 images per batch, all profiles. Pro ($3.99/mo): unlimited batch, format conversion, AVIF.

I'd appreciate any feedback on the compression approach or UX. Happy to answer questions about the architecture.

Ask HN: Agentic search vs. RAG – what's your production experience?

Hacker News - Tue, 02/24/2026 - 3:07am

There's been a clear shift from 2023's you need RAG to 2026's agentic search outperforms RAG.

We made the switch at Cosmico when building AI-native applications with Claude Code. Agentic search gives us better accuracy but at higher cost per query.

For those running production systems:

1. What prompted your switch (or decision to stick with RAG)? 2. What broke during the transition? 3. What's your hybrid approach (if any)?

Specifically curious about code search vs. document retrieval use cases, and how you handle the latency/cost trade-offs.

Our context: building custom software with AI agents in weeks, not months. Accuracy matters more than speed for our workflow, but that's not universal.

What's working (or not working) for you?

Ask HN: What should be done to prevent world control by pedo-rings of satanists

Hacker News - Tue, 02/24/2026 - 2:24am

Jeffrey Epstein’s case is absolutely real, horrifying, and proves that powerful people can commit and hide systemic abuse for years. The full extent of the control of powerful figure is not yet clear but we can see it is massive

Show HN: A Claude Code hook that sends you to bed

Hacker News - Tue, 02/24/2026 - 2:09am

Coding agents are addictive and I stay up too late playing with them.

This hook makes Claude code nudge me to go to sleep when it's past my bedtime. It works! Goodnight! :)

Ask HN: How do you prove a privileged infra change ran as approved?

Hacker News - Tue, 02/24/2026 - 2:08am

A Terraform apply, a DB migration, a secret rotation, a break glass access grant. These are the kinds of mutations that can cause real damage if they go wrong, or if you later need to explain exactly what happened.

In many environments, evidence of these changes ends up scattered across logs, CI systems, ticketing tools, and control planes. Reconstructing a single change months later can mean querying multiple systems that may not retain state indefinitely.

I am exploring a simple idea: treating each privileged mutation as something that emits a portable, signed receipt. The receipt would tie together what was authorized, who approved it, what ran, and what the resulting state was. The goal is that it could be verified offline, without querying the original system.

There is a draft spec here: https://github.com/reciprium/spec

It defines a receipt format using JSON Schema, CDDL, and Protobuf, with test vectors and worked examples for Terraform, GitOps workflows, database migrations, secret rotation, and break glass access.

I would appreciate perspective from people who operate infrastructure at scale:

1. How do you currently record that a privileged change was authorized, executed as approved, and verified afterward?

2. Could you reconstruct a complete audit of a specific change from six months ago without relying on your CI or control plane?

3. During audits or incidents, how do you demonstrate that a change matched its approval?

4. Would a signed, portable receipt for each mutation materially simplify anything for you, or does this problem already feel solved?

5. Where in your workflow would something like this naturally attach, if at all?

I am trying to understand whether the problem exists in the form described, or whether practitioners have converged on better patterns. Critical feedback is especially useful.
