Show HN: I Built Tinyfocus – A Minimal Tool to Help Solo Founders Focus Hi HN, I just launched Tinyfocus, a small productivity tool designed specifically for solo founders and builders. The goal is simple: help you focus on what matters and get more done in less time. Here’s what Tinyfocus does: Lets you track your top tasks and prioritize efficiently. Provides micro dashboards to keep your daily focus in check. Lightweight, no distractions, no fluff. I built it entirely by myself, iterating in public, and I wanted to share it with the community to get feedback. It’s been crazy seeing how a simple tool can make such a difference in daily focus, especially when you’re juggling multiple projects as a solo founder. Check it out here: tinyfoc.us I’d love to hear your thoughts – any feedback, feature ideas, or bugs you notice. Thanks! https://ift.tt/UpBhrue November 30, 2025 at 11:35PM

Show HN: Zero-power photonic language model–code The model uses a 1024-dimensional complex Hilbert space with 32 layers of programmable Mach–Zehnder meshes (Reck architecture) and derives token probabilities directly via the Born rule. Despite using only unitary operations and no attention mechanism, a 1024×32 model achieves coherent TinyStories generation after < 1.8 hours of training on a single consumer GPU. This is Part 1 - the next step is physical implementation with $50 of optics from AliExpress. https://zenodo.org/records/17764289 November 30, 2025 at 12:15AM

Show HN: Superglue – OSS integration tool that understands your legacy systems If you've ever worked in a large company, you've probably encountered "shadow infrastructure": scripts nobody understands or custom connectors written once and never touched again. This glue layer isn't documented, isn't owned by anyone, and tends to break when systems are upgraded or someone leaves. It's also the part everybody dreads working on, because it's hard to understand, painful to work with, and full of unknown unknowns. We built superglue so that engineers stop wasting time on deciphering legacy APIs and documentation. superglue ingests existing glue code, SQL, configs, docs, OpenAPI specs and reverse-engineers what the system is actually doing. It then maps dependencies and regenerates everything as clean javascript code that can run directly or be exposed via MCP or SDK. It also monitors API changes and schema drift, and automatically repairs integrations when u...

Show HN: Makefiles, Metalanguages, Matrioshka Automata Immediately buried last time, so reposting for your lazy Sunday. This project is a strange labor of love, practically guaranteed to inspire horror and delight. It's also tough to summarize. Partly it's very practical and involves familiar tools, but part of it is also a new programming language with esolang roots. I'll start with the practical and move towards the peculiar. The one-sentence summary: compose.mk brings docker-fluency, polyglots, and a capable standard library to Makefiles. A more in-depth elevator pitch from the main landing page is below, and some related links at the end in footnotes 1-5. > Meet compose.mk, a tool / library / framework for Makefile-based automation, scripting, and lightweight orchestration. Native support for docker, docker-compose, workflow primitives, JSON IO, TUI elements, and more, all provided by a single file with no dependencies beyond what's already in your development en...

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 metri...

Show HN: ToolHop – Fast, simple utilities for every workflow ToolHop is your all-in-one browser toolbox with 200+ fast-loading calculators, converters, generators, color labs, and dev helpers. Use global search or curated categories to jump straight into the right utility, run it client-side for instant feedback, and deep-link results to your team. Whether you’re formatting copy, validating data, checking DNS, or exploring palettes, ToolHop keeps your core workflows a single tab away, and it’s entirely free, no account required. --- I built ToolHop because I was sick of the usual “free tool” bait-and-switch. Every time I needed to convert an image, compress a file, check some text, or run a quick calculation, I’d end up hitting some arbitrary limit like “10 uses per week” or a forced signup wall. It’s ridiculous how something as basic as converting a JPG to a PNG can turn into a subscription pitch. So ToolHop started as a personal frustration project: I wanted a single place with a ton...

Show HN: DeepClause – A Neurosymbolic AI System Built on WASM and Prolog Hi HN, Today I'd like to present the results of my weekend project of the last year or so. Given there are many posts on HN about LLMs and Prolog, I thought that this would be of interest. DeepClause is my own (possibly misguided :-) attempt at combining LLMs with Logic Programming, ultimately hoping to establish a foundation for building more reliable agents, that produce reproducible and fully traceable result. At the heart of DeepClause is a DSL called "DeepClause Meta Language" (DML) which can be used to encode agent behaviors as executable logic programs. DML is executed by a meta-interpreter implemented in Prolog and thus natively supports things like constraint logic programming, knowledge graphs, symbolic reasoning, ... The DML interpreter itself runs inside the SWI Prolog WASM module, thus allowing for a secure and sandboxed execution environment for AI agents. The project is still rough aro...

Show HN: ByteSync – Open-source hybrid file sync (LAN and remote, E2EE) Hi everyone, I've been developing ByteSync, an open-source file synchronization, backup and deduplication tool designed to bridge the gap between local and remote sync. In spirit, it's somewhat closer to FreeFileSync, but with an integrated networking layer and end-to-end encryption — which means you can synchronize files between computers on the same LAN or across the internet without VPNs or firewall setup. Everything works transparently through the same interface. The synchronization model is based on DataNodes (which represent repositories, such as servers or NAS devices) and DataSources (the folders or files inside them). A session can include multiple participants, each with one or several DataNodes, and ByteSync handles all comparisons and transfers automatically. To optimize performance, the engine uses a two-stage inventory process: an initial indexation followed by comparisons limited to items tha...

Show HN: Cancer diagnosis makes for an interesting RL environment for LLMs Hey HN, this is David from Aluna (YC S24). We work with diagnostic labs to build datasets and evals for oncology tasks. I wanted to share a simple RL environment I built that gave frontier LLMs a set of tools that lets it zoom and pan across a digitized pathology slide to find the relevant regions to make a diagnosis. Here are some videos of the LLM performing diagnosis on a few slides: ( https://www.youtube.com/watch?v=k7ixTWswT5c ): traces of an LLM choosing different regions to view before making a diagnosis on a case of small-cell carcinoma of the lung ( https://youtube.com/watch?v=0cMbqLnKkGU ): traces of an LLM choosing different regions to view before making a diagnosis on a case of benign fibroadenoma of the breast Why I built this: Pathology slides are the backbone of modern cancer diagnosis.

Show HN: Easily reduce GitHub Actions costs with Ubuntu-slim migration Hi, HN! I've been running GitHub Actions workflows for a while, and when GitHub announced ubuntu-slim runners as a cheaper alternative to ubuntu-latest, I wanted to migrate. (Blog: https://ift.tt/ArWfEP5... ) But manually checking which workflows can safely migrate is tedious—you need to check for Docker usage, services, containers, execution times, and missing commands. So I built gh-slimify, a GitHub CLI extension that automates this. It scans your workflows, detects migration candidates, checks for incompatible patterns, identifies missing commands, and can safely update workflows with one command. Try it: gh extension install fchimpan/gh-slimify gh slimfy # Scan workflows gh slimfy fix # Update safe jobs only Open source (MIT). I'd love feedback on how to improve it or what edge cases I might have missed. https://ift.tt/WgEIx9n November 8, 2025 at 10:19PM

Show HN: TabPFN-2.5 – SOTA foundation model for tabular data I am excited to announce the release of TabPFN-2.5, our tabular foundation model that now scales to datasets of up to 50,000 samples and 2,000 features - a 5x increase from TabPFN v2, published in the Nature journal earlier this year. TabPFN-2.5 delivers state-of-the-art predictions in one forward pass without hyperparameter tuning across classification and regression tasks. What’s new in 2.5 : TabPFN-2.5 maintains the core approach of v2 - a pretrained transformer trained on more than hundred million synthetic datasets to perform in-context learning and output a predictive distribution for the test data. It natively supports missing values, cateogrical features, text and numerical features is robust to outliers and uninformative features. The major improvements: - 5x scale increase: Now handles 50,000 samples × 2,000 features (up from 10,000 × 500 in v2) - SOTA performance: TabPFN-2.5 outperforms tuned tree-based methods and...

Show HN: I built a highly customizable mental arithmetic trainer for iOS Mental arithmetic has been a hobby of mine for a while. It's fun and good exercise for your brain. When I switched to iOS, I couldn’t find a decent app. Most had ads, sign-ups, excessive gamification, or mandatory subscriptions, and none were customizable enough. So I built my own. Athena Math lets you - Practice operations not normally found in mental math apps: modulo, square roots, percents, GCD and LCM - Tailor each session: set your time or problem limits, choose digit ranges (1–5), mix digit lengths (e.g. 55 + 436), and select any combination of operations you like. - A detailed stats screen that shows the time you spent on problems, problems per day, percent correct, etc. All graphs are filterable. - A history screen that shows all your sessions. - You can import and export your history for offline analysis or to transfer - Offline tutorials are included for all operations - Lastly, you can use it immed...

Show HN: I built a smart blocker after destroying my dopamine baseline I'm a solo dev. A few years ago, I got addicted to Reddit. Spent months in that loop. Being a programmer, I thought I'd be clever. Redirected Reddit's domain to nowhere in my DNS file. Worked great until I'd just... open the file and undo it 20 minutes later. So I made it irreversible. Locked the DNS file so it can't be edited unless I boot my Mac in safe mode. And if I do that, there's a script that instantly locks it again. Haven't used Reddit since last year. Problem solved, right? Wrong. I just replaced Reddit with Twitch and YouTube. Started keeping streams running in the background while I coded. This went on for almost a year. It killed my ability to focus. If you know about dopamine, you know your brain releases it when it wants you to repeat an activity. The constant background streams destroyed my dopamine baseline. When I tried to code without anything running one day, it felt ...

Show HN: Why write code if the LLM can just do the thing? (web app experiment) I spent a few hours last weekend testing whether AI can replace code by executing directly. Built a contact manager where every HTTP request goes to an LLM with three tools: database (SQLite), webResponse (HTML/JSON/JS), and updateMemory (feedback). No routes, no controllers, no business logic. The AI designs schemas on first request, generates UIs from paths alone, and evolves based on natural language feedback. It works—forms submit, data persists, APIs return JSON—but it's catastrophically slow (30-60s per request), absurdly expensive ($0.05/request), and has zero UI consistency between requests. The capability exists; performance is the problem. When inference gets 10x faster, maybe the question shifts from "how do we generate better code?" to "why generate code at all?" https://ift.tt/5dpeUA2 November 1, 2025 at 11:15PM
