Ask HN: Hearing aid wearers, what's hot?

One of my Phonak Audeo 90’s (RIC) died the other day after 5 years and I’m shopping for new. What’s your go to hearing aid currently if you’ve upgraded recently or have been thinking of doing so?

Moderate loss, have worn them for many years, enjoy listening to music and nature, but also need help in meetings and noisy environments.

Not worried about cost and wanting to get one more good deal out of work insurance before I retire.

Show HN: I wrote a minimal memory allocator in C

A fun toy memory allocator (not thread safe, that's a future TODO). I also wanted to explain how I approached it, so I also wrote a tutorial blog post (~20 minute read) covering the code which you can find the link to in the README.

Ask HN: Good resources to learn financial systems engineering?

I work mainly in energy market communications and systems that facilitate energy trading, balancing and such. Currently most parties there take minutes to process messages and I think there could be a lot to learn from financial systems engineering. Any good resources you can recommend?

Show HN: I built a wizard to turn ideas into AI coding agent-ready specs

I created vibescaffold.dev. It is a wizard-style AI tool that will guide you from idea → vision → tech spec → implementation plan. It will generate all the documents necessary for AI coding agents to understand & iteratively execute on your vision.

How it works: - Step 1: Define your product vision and MVP - Step 2: AI helps create technical architecture and data models - Step 3: Generate a staged development plan - Step 4: Create an AGENTS.md for automated workflows

I've used AI coding tools for awhile. Before this workflow (and now, this tool), I kept getting "close but not quite" results from AI coding tools. I learned that the more context & guidance I gave these tools up front, the better results I got.

The other thing I have found with most tools that attempt to improve on "vibe coding" is that they add abstraction. To me, this just adds to the problem. AI coding agents are valuable, but they are error-prone - you need to be an active participation in their work. This workflow is designed to provide a scaffolding for these AI agents, while minimizing additional abstraction.

Would love feedback on the workflow - especially curious if others find the upfront planning helpful or constraining.

Show HN: Build the habit of writing meaningful commit messages

Too often I find myself being lazy with commit messages. But I don't want AI to write them for me... only i truly know why i wrote the code i did.

So why don't i get AI to help me get that into words from my head?

That's what i built: smartcommit asks you questions about your changes, then helps you articulate what you already know into a proper commit message. Captures the what, how, and why.

Built this after repeatedly being confused 6 months in a project as to why i made the change i had made...

Would love feedback!

Show HN: Forty.News – Daily news, but on a 40-year delay

This started as a reaction to a conversational trope. Despite being a tranquil place, even conversations at my yoga studio often start with, "Can you believe what's going on right now?" with that angry/scared undertone.

I'm a news avoider, so I usually feel some smug self-satisfaction in those instances, but I wondered if there was a way to satisfy the urge to doomscroll without the anxiety.

My hypothesis: Apply a 40-year latency buffer. You get the intellectual stimulation of "Big Events" without the fog of war, because you know the world didn't end.

40 years creates a mirror between the Reagan Era and today. The parallels include celebrity populism, Cold War tensions (Soviets vs. Russia), and inflation economics.

The system ingests raw newspaper scans and uses a multi-step LLM pipeline to generate the daily edition:

OCR & Ingestion: Converts raw pixels to text.

Scoring: Grades events on metrics like Dramatic Irony and Name Recognition to surface stories that are interesting with hindsight. For example, a dry business blurb about Steve Jobs leaving Apple scores highly because the future context creates a narrative arc.

Objective Fact Extraction: Extracts a list of discrete, verifiable facts from the raw text.

Generation: Uses those extracted facts as the ground truth to write new headlines and story summaries.

I expected a zen experience. Instead, I got an entertaining docudrama. Historical events are surprisingly compelling when serialized over weeks.

For example, on Oct 7, 1985, Palestinian hijackers took over the cruise ship Achille Lauro. Reading this on a delay in 2025, the story unfolded over weeks: first they threw an American in a wheelchair overboard, then US fighter jets forced the escape plane to land, leading to a military standoff between US Navy SEALs and the Italian Air Force. Unbelievably, the US backed down, but the later diplomatic fallout led the Italian Prime Minister to resign.

It hits the dopamine receptors of the news cycle, but with the comfort of a known outcome.

Stack: React, Node.js (Caskada for the LLM pipeline orchestration), Gemini for OCR/Scoring.
