Show HN: Lend Me Your Ears – A Simon-style ear training game with MIDI supporthttps://lend-me-your-ears.specr.net“Lend Me Your Ears” is an interactive web-based game inspired by the classic Simon toy (originally by Milton Bradley). It presents players with a sequence of musical notes and challenges them to reproduce the sequence using either an on-screen piano or a connected MIDI keyboard. Each correct response leads to a progressively more difficult sequence, testing the player’s concentration, memory, and pitch recognition.The game features two modes:- Simon Mode (focuses on auditory recall)- Practice Mode (displays standard sheet music notation to support learning)The game also includes options for key signature selection, dyads, and a metronome to enhance the training experience.

Show HN: Qpost.dev – An open API to post to TikTok, YT, and IG in one placehttps://qpost.devHi HN! I built QPost (https://qpost.dev), a tool for scheduling and publishing content across YouTube, TikTok, and Instagram from a single interface.*What it does:*- Schedule posts across multiple platforms simultaneously- Platform-specific metadata (YouTube titles/descriptions, TikTok hashtags, Instagram captions)- Automated publishing via cron jobs- Account management for multiple social accounts- Real-time post queue with status tracking (scheduled, posted, failed)*Tech stack:*- Astro + React for the frontend- Prisma + PostgreSQL for data- Better-auth for authentication- Google Cloud Storage for media- node-cron on a Digital Ocean droplet*Why I built it:*Most social media schedulers are either expensive SaaS products or locked behind complex enterprise tools. I wanted something free to use and easy to incorporate into a workflow.*What was challenging:*Each platform has its own quirks – TikTok's creator API, YouTube's OAuth scopes, Instagram's Graph API.

Ask HN: Retro Games for Kidshttps://news.ycombinator.com/item?id=46522926I grew up with a Commodore 128. I used it mostly in C64 mode and spent a lot of time playing games, even though I only had a datasette. Now I have two kids (8 and 6) and after beginning elementary school the older one is asking for a game console :-) We will eventually get one, but in the meantime I thought of installing a C64 emulator on my old laptop and use a semi broken PS joystick to let them play some retro games. I am planning to install Pit Stop II, Boulder Dash, Great Giana Sisters, Crackout, International Karate and probably more. While doing this, it occurred to me that I am not restricted to C64, I can install an Amiga simulator (I envied Amiga when I was a kid, but could not afford one) and have access to a lot more games, with much better sound and graphics (I don't mean to start a war).Do you have game recommendations or other tips for such a project? I am willing to install other simulators as well, if it can be done via RetroArch on Debian.

Show HN: Vy, a cross platform AI agent that automates apps without APIshttps://vercept.com/Hi HN, I am Kiana, I was an AI researcher for 10 years, and since last November I have been working on Vy. Vy is a desktop app for Mac and Windows. It sees your screen and controls mouse and keyboard to automate workflows across apps, including ones without APIs. I know there is a lot of skepticism about AI agents, and I share some of it. A lot of things in this space look impressive in demos and then fall apart on real, boring work. So here are a few concrete things that Vy does today that we and early users actually rely on: Where it works best Tasks that you could explain in a paragraph and that take a human a few minutes, not hours.Workflows that mostly involve clicking, typing, scrolling, and copying between a few known tools.Where it does not work well Very long, unsupervised runs. It is better to keep tasks bounded and keep an eye on it.Pixel precise work like detailed design or brush based editing.Some custom web editors or highly dynamic UIs still confuse it.How it is differen

Why machine learning fails at prioritization problemshttps://news.ycombinator.com/item?id=46521799Why Machine Learning Fails at Prioritization ProblemsMachine learning has been enormously successful at perception tasks: vision, speech, translation, classification. But over the last few months, I’ve become convinced it’s the wrong abstraction for a large class of problems that show up in real businesses.These aren’t problems about recognition. They’re problems about prioritization.What I mean by “prioritization problems”In many operational settings, the task isn’t to predict an outcome in isolation. It’s to decide what to act on next given limited time and resources.Examples: • Which customers should a team focus on today? • Which accounts are most at risk right now? • Which leads are worth human attention this week? • Which cases should be escalated first?In practice, these problems reduce to ranking entities, not labeling them. The top of the list matters far more than global accuracy metrics.Why accuracy is a misleading objectiveMost ML systems optimize for accuracy (or AUC, log

Launch HN: Tamarind Bio (YC W24) – AI Inference Provider for Drug Discoveryhttps://news.ycombinator.com/item?id=46515777Hi HN, we're Deniz and Sherry from Tamarind Bio (https://www.tamarind.bio). Tamarind is an inference provider for AI drug discovery, serving models like AlphaFold. Biopharma companies use our library of leading open-source models to design new medicines computationally.Here’s a demo: https://youtu.be/luoMApPegloTwo years ago, I was hired at a Stanford lab to run models for my labmates. Some post-doc would ask me to run a set of 1-5 models in sequence with tens of thousands inputs and I would email them back the result after setting up the workflow in the university cluster.At some point, it became unreasonable that all of an organization's computational biology work would go through an undergrad, so we built Tamarind as a single place for all molecular AI tools, usable at massive scale with no technical background needed. Today, we are used by much of the top 20 pharma, dozens of biotechs and tens of thousands of scientists.When we started getting adoption in the big pharma companies,

Show HN: Kafka-compatible streaming on S3 with stateless brokershttps://news.ycombinator.com/item?id=46514822Hi HN,KafScale is Kafka-compatible streaming, k8s native, where S3 is the source of truth and brokers hold no persistent state. Written in Go, runs on Kubernetes.Built this after years of operating Kafka and hitting the same walls: broker failures that take hours to recover, partition rebalancing that blocks deploys, disk capacity planning that never ends.How it works:- Producers and consumers use standard Kafka clients - Brokers buffer in memory, flush to S3 - etcd stores metadata and consumer group state - Recovery means restarting a pod and reading from S3 - Optional Iceberg processor reads segments directly from S3, bypasses brokers entirely for batch/analytical workloadsWhat you give up: latency is 400-500ms (S3 round-trip), no transactions, no compacted topics. It's not a 100% replacement.What you get: brokers are disposable, scaling is just replica count, no disk management, direct access to streamed data over S3 ACLLicense: Apache 2.0 GitHub: https://github.com/novatechflow/kaf

What I Expected from Computer Engineering and Notes on first public projecthttps://news.ycombinator.com/item?id=46512389Am I expecting too much from a university degree? As someone early in my career, can I still contribute to the education of our field?I’d appreciate advice on learning in public and on whether the approach below makes sense.I’m a 19-year-old programmer from Brazil. I’ve been working on systems for aerospace machining facilities since I was 17. As I’ve learned more about professional software development, I’ve also realized how messy my early code was—which I think is a normal part of learning.I started a Computer Engineering degree at a state university when I was 18. So far, the experience has been far from what I expected. Many courses feel disconnected from real systems or hardware, with exercises that seem abstract and rarely connected to each other.If calculus I, II, and III are essential to solving computer engineering problems, why do we mostly work with artificial examples? If concepts like frequency filters and statistics are foundational to real systems, why are they often ta

Beyond 1s and 0s: Can AI Reason Without the Ability to Ask "Why?"https://news.ycombinator.com/item?id=46511704Today at CES 2026, Jensen Huang stated: "Physical AI requires three computers."An AI Supercomputer (DGX) to train the brain. A Simulation Computer (Omniverse) to simulate the world (Expectation). A Robot Computer (Jetson) to act in the real world (Observation).The core of this architecture is the intentional separation of Simulation and Reality—designed to create a "Sim-to-Real Gap." When the simulation says "this floor is safe" but the robot feels "slippery," that gap forces the system to become smarter.For months, I have been applying this same principle to pure information and logic.My core argument: We must engineer intentional contradiction.Current AI: Input -> Pattern Match -> Output (1 or 0). Fast. Efficient. Hollow.What I propose: Input -> Detect Gap (A ≠ B) -> Ask "Why?" -> Search -> Resolve -> Output (1 or 0). Slower. But there is a process.The final output is still binary. But the path mirrors human reasoning: Recognizing something does not fit. Asking "Why?" Searching for m
