Show HN: A site for YC rejection stories https://ift.tt/p8yrUix

Show HN: A site for YC rejection stories Got rejected from YC a few times, so I built a site to collect lessons, reflections, and what people would do differently next time. Thought it could be helpful since most founders apply more than once anyway :) Hope it's helpful: https://ift.tt/duglFQC https://ift.tt/duglFQC June 1, 2025 at 02:15AM

Show HN: LaminarFlow – AI-native, open-source finance platform for startups https://ift.tt/Dut5ryd

Show HN: LaminarFlow – AI-native, open-source finance platform for startups I'm Yash, and I'm building LaminarFlow — an AI-native, open-source platform to help startups, founders, SMBs, manage their fincial ops more efficiently. It brings together financial insights, banking, invoicing, payment tracking, time tracking, and banking-style reconciliation — all powered by an AI agent that automates the boring stuff. We’re building this as an open startup, sharing everything publicly, and keeping it fully open-source (MIT). Would love your feedback and thoughts! https://www.lamflo.xyz May 31, 2025 at 09:31PM

Show HN: Icepi Zero – The FPGA Raspberry Pi Zero Equivalent https://ift.tt/rwcvZkm

Show HN: Icepi Zero – The FPGA Raspberry Pi Zero Equivalent I've been hacking away lately, and I'm now proud to show off my newest project - The Icepi Zero! In case you don't know what an FPGA is, this phrase summarizes it perfectly: "FPGAs work like this. You don't tell them what to do, you tell them what to BE." You don't program them, but you rewrite the circuits they contain! So I've made a PCB that carries an ECP5 FPGA, and has a raspberry pi zero footprint. It also has a few improvements! Notably the 2 USB b ports are replaced with 3 USB C ports, and it has multiple LEDs. This board can output HDMI, read from a uSD, use a SDRAM and much more. I'm very proud the product of multiple weeks of work. (Thanks for the pcb reviews on r/PrintedCircuitBoard ) (All the sources on github under an open source license :D) PS. See some more pics on reddit https://ift.tt/Jt9ZNqi... https://ift.tt/gpFQokP May 28, 2025 at 08:31PM

Show HN: Asdf Overlay – High performance in-game overlay library for Windows https://ift.tt/pn3clLf

Show HN: Asdf Overlay – High performance in-game overlay library for Windows I am making a open source overlay library. Game overlay is for rendering contents on top of game screen. Representative examples are Discord and Steam in-game overlay. They are complicated because it has to hook rendering part of a game. Asdf overlay provides easy to use interfaces for rendering on top of game screen. I recognize game performance degradation due to overlay rendering, so GPU shared texture was used to avoid CPU framebuffer copy. Asdf Overlay is capable of rendering full screen overlay without noticeable performance loss. https://ift.tt/xyOlGn9 May 31, 2025 at 01:27AM

Show HN: Technical Interviews Built for 2025 https://ift.tt/V5lGioK

Show HN: Technical Interviews Built for 2025 Hey HN, The way we hire engineers made sense in 2015. But in 2025, when engineers use AI tools daily, we're still testing algorithm memorization on whiteboards.. That's why we're building DevDay. DevDay is built for the new reality of modern engineering work: candidates collaborate with AI teammates, delegate tasks to AI agents, and solve problems using the tools they'd actually use on the job (LLMs, git, and Slac(k) for team communication). The old interview playbook is fundamentally broken: - Whiteboard anxiety tests don't predict performance - Take-home tests and virtual paired programming get gamed with ChatGPT - Algorithm memorization has zero correlation with debugging prod issues (what you actually deal with in your day to day work) Here is what we are not: X Another LeetCode clone with AI buzzwords X Replacing engineers with AI X "Disrupting" hiring with magic algorithms What it actually does: - Tests AI...

‘On Your Left’ and E-Bikes: SFMTA Employees’ Tips on Successful Bike Commuting

‘On Your Left’ and E-Bikes: SFMTA Employees’ Tips on Successful Bike Commuting By Madhu Unnikrishnan Members of our SFMTA bike-commute panel: From left, Julia Friedlander, Michael Rhodes and Jack Anninos (not pictured: Elliot Goodrich, Christy Osorio and Miriam Sorell). Between our typically mild weather and expansive bicycle network, San Francisco is pretty much ideal for bike commuting. And indeed, the city has among the highest percentage of bike commuters in the U.S. We’ve done a lot of work to make San Francisco more bike friendly. We have a 400-mile bike network that includes more than 130 miles of dedicated bike lanes, 87 miles of off-street paths and 51 miles of bike lanes that are...

Show HN: Octogen: e-commerce capabilities for agents https://ift.tt/xiclM5b

Show HN: Octogen: e-commerce capabilities for agents Hi HN, We just released a public beta of e-commerce capabilities for AI agents — aimed at developers building shopping agents or personal assistants. It’s early and buggy, but we’d love your feedback. Try a live demo here: https://ift.tt/OkKw5Db --- ## Why we built this We believe the biggest *technical* bottleneck in building consumer e-commerce agents is fragmented product data and inconsistent schemas across online stores. So we created a high-fidelity yet unified interface for *e-commerce catalog + checkout*, regardless of the underlying platform. --- ## What it does We currently offer two core capabilities: ### 1. Unified product catalog (for LLM-style search) - Octogen automatically wrangles any ecommerce site into a common schema — a superset of `schema.org/Product`. - It works across platforms and is available today for hundreds of sites. - You can request new stores — ~95% are processed fully autonomously. - Useful for agent...

Show HN: Burner Bitcoin – a simple hardware wallet for gifting Bitcoin https://ift.tt/gq0xc7R

Show HN: Burner Bitcoin – a simple hardware wallet for gifting Bitcoin Hello HN! Late last year we launched Burner, a low cost Ethereum hardware wallet for gifting crypto. It's a card-sized wallet that generates and stores cryptocurrency keys with no need to manage seed phrases or private keys. It operates entirely through your smartphone browser and NFC. We've produced tens of thousands of Burners to date, primarily for gifting and partner collaborations (e.g. conference handouts). Today we're launching our most requested feature: a Bitcoin compatible Burner. Burner Bitcoin features nearly identical hardware to the Ethereum variant -- a secure element chip with NFC capabilities in colorful/translucent plastic -- however, we made the decision to split the Bitcoin and Ethereum versions into two products rather than creating a single monolithic wallet. This is because we're seeing that both end users and business customers want to use Burner as a tool to give specific ass...

Show HN: I built a chill place online to work on your ideas https://ift.tt/CZ7lyI9

Show HN: I built a chill place online to work on your ideas I used to watch hundreds of hours of lofi beats on youtube while I was coding, but I got really sick of all the ads. I decided to build a better alternative - It's a configurable space for you to hang out online while you work, with a ton of relaxing music and backgrounds. Its got useful tools built in like a timer to keep track of how long you've been locked in, and a notepad for todos or scribbling down ideas while you work. Honestly this is the first tool I've built that I personally use every day, so I'm hoping some of you out there can get some use out of it too! https://lofizone.com May 25, 2025 at 05:38AM

Show HN: 1min Workouts for People Who Sit All Day https://ift.tt/x3acqmD

Show HN: 1min Workouts for People Who Sit All Day I am a software developer and in the last few months after recently becoming a father I was barely finding time for a proper workout. Recently I was reading about new research on Snack Exercises and how beneficial mini workouts of less than 2mins every so often, during the day are to our body. So, I decided to build an iOS App for me and others to help with this. The app generates a list of exercises that I need to tick to complete daily or loose my streak. The algorithm takes into account muscle groups and balancing the exercises to hit most main muscles. I also stayed going through all exercises and adding a couple of alternative exercises in case I don't feel like the recommended exercise. Since I'm not a trainer I commissioned professional exercise posture video guides and animations by an exercise expert which I attached to each exercise. I uploaded the app on the app store for free and no ads. If this is something that int...

Show HN: Can AI Help Designers Ideate Better? We Spent 5 Wks Finding Out https://ift.tt/OVQ7boP

Show HN: Can AI Help Designers Ideate Better? We Spent 5 Wks Finding Out We set out to answer a simple but deep question: Can AI actually practically help product designers improve during the discovery and ideation phase of the design process? So we spent 5 weeks running an experiment. We mapped every tool we use for discovery: Mobbin, Dribbble, Pinterest, Twitter, Behance We broke down typical design thinking and brainstorming workflows We reviewed every prototyping or idea-capturing tool we’ve used Then we tried building lightweight AI workflows with various LLM tools and frameworks Result: Yes. Used well, AI can significantly improve design thinking — especially for junior/mid-level designers — by offering faster idea generation, design critiques, and creative merges. Out of that research, we built Moonchild: A discovery-stage design ideation tool that: Generates thoughtful UI concepts from minimal prompts Allows asking design questions and getting structured critique Merges styles,...

Show HN: hcker.news – an ergonomic, timeline-based Hacker News front page https://ift.tt/ZJta7gk

Show HN: hcker.news – an ergonomic, timeline-based Hacker News front page Hi folks, I've built an alternative Hacker News front page. It is inspired by and meant to be a replacement for hckrnews.com. I built this because HN is woefully underfeatured, but most sites that try to improve it seem to assume that the visual design is the problem. hcker.news tries to maintain HN's familiarity while adding useful enhancements. There are three primary views: - Timeline View: Browse top stories by votes or comments grouped by day, week, or month (e.g., top 20 per day, top 100 per week). - Aggregate View: See top stories by votes or comments over custom time ranges. - Front Page View: The original HN front page, untouched. Feed Filtering: - Custom Keyword Filters: Include/exclude keywords (e.g., include "Rust," exclude "DOGE") or set a minimum score threshold. - No HN Algorithm: Timeline and Aggregate Views show stories usually downranked by the HN algo (e.g., flagged ...

Show HN: Pi Co-pilot – Evaluation of AI apps made easy https://ift.tt/vN8jVkz

Show HN: Pi Co-pilot – Evaluation of AI apps made easy Hey HN — 2 months ago we shared our first product with the HN community ( https://ift.tt/RKNCuSA ). Despite receiving lots of traffic from HN, we didn’t see any traction or retention. One of our major takeaways was that our product was too complicated. So we’ve spent the last 2 months iterating towards a much more focused product that tries to do just one thing really well. Today, we’d like to share our second launch with HN. Our original idea was to help software engineers build high-quality LLM applications by integrating their domain knowledge into a scoring system, which could then drive everything from prompt tuning to fine-tuning, RL, and data filtering. But what we quickly learned (with the help of HN – thank you!) is that most people aren’t optimizing as their first, second, or even third step — they’re just trying to ship something reasonable using system prompts and off-the-shelf models. In looking to build a product that...

Show HN: Racketmeter – Measure Badminton String Tension Using Sound Frequency https://ift.tt/aGnxTbq

Show HN: Racketmeter – Measure Badminton String Tension Using Sound Frequency Racketmeter lets badminton players measure string tension using the sound frequency produced when tapping the racket strings. It's 100% free, works in your browser on mobile and desktop, and requires no sign-up or installation. I built it to solve a personal problem. I started playing badminton regularly in 2016 and quickly learned that players often ask stringers to string rackets at specific tensions (like 22 or 26 lbs). But after a few stringing jobs, I began to feel like the tension was inconsistent. Other players told me they just tap the strings and go by ear where "sharper sound meant higher tension." One day while tuning my guitar, I could see exact sound frequencies on my tuner app. That’s when it clicked. It should be possible to build a tuner for badminton strings as well! I searched online and found some tension-frequency data shared by professional stringers, but it wasn’t clean or ...

Show HN: Buckaroo – The data table UI for Notebooks https://ift.tt/bWiGx9u

Show HN: Buckaroo – The data table UI for Notebooks Buckaroo is my open source project. It is a dataframe viewer that has the basic features we expect in a modern table - scroll, search, sort. In addition there are summary stats, and histograms available. Buckaroo support Pandas and Polars dataframes and works on Jupter, Marimo, VSCode and Google Colab notebooks. All of this is extensible. I think of Buckaroo as a framework for building table UIs, and an initial data exploration app built on top of that framework. AG-Grid is used for the core table display and it has been customized with a declarative layer so you don't have to pass JS functions around for customizations. On the python side there is a framework for adding summary stats (with a small DAG for dependencies). There is also an entire Low Code UI for point and click selection of common commands (drop column). The lowcode UI also generates a python function that accomplishes the same tasks. This is built on top of JLisp -...

Show HN: Blacklight – secret scanner for code, databases, drives, and slack https://ift.tt/3HGfqYS

Show HN: Blacklight – secret scanner for code, databases, drives, and slack We often ran pattern matching searches for secrets and keys across codebases, databases etc. Therefore, we thought about converting that workflow into a tool that we could just easily generate a SARIF report and share with our customers. Blacklight is a powerful secret, key, and sensitive data scanning tool that helps you detect and prevent sensitive information leaks in your codebase, databases, cloud storage, and communication platforms. The idea is that one can add their custom rules around their governance and compliance requirements. The platform comes with 114 matching criteria, but this can be extended easily. https://ift.tt/Ek1ad9x May 18, 2025 at 01:40AM

Show HN: I built a knife steel comparison tool Hey HN! I'm a bit of a knife steel geek and got tired of juggling tabs to compare stats. So, I built this tool: https://ift.tt/dSuPbGn It lets you pick steels (like the ones in the screenshot) and see a radar chart comparing their edge retention, toughness, corrosion resistance, and ease of sharpening on a simple 1-10 scale. [Maybe attach the screenshot here if HN allows, or link to it] It's already been super handy for me, and I thought fellow knife/metallurgy enthusiasts here might find it useful too.

Show HN: Workflow Use – Deterministic, self-healing browser automation (RPA 2.0) https://ift.tt/t6ekc1E

Show HN: Workflow Use – Deterministic, self-healing browser automation (RPA 2.0) Hey HN – Gregor & Magnus here again. A few months ago, we launched Browser Use ( https://ift.tt/28anpJF ), which let LLMs perform tasks in the browser using natural language prompts. It was great for one-off tasks like booking flights or finding products—but we soon realized enterprises have somewhat different needs: They typically have one workflow with dynamic variables (e.g., filling out a form and downloading a PDF) that they want to reliably run a million times without breaking. Pure LLM agents were slow, expensive, and unpredictable for these high-frequency tasks. So we just started working on Workflow Use: - You show the browser what to do (by manually recording steps; show don’t tell). - An LLM converts these recordings into deterministic scripts with variables (scripts include AI steps as well, where it’s 100% agentic) - Scripts run reliably, 10x faster, and ~90% cheaper than Browser Use. - If...

It might be a little bit slow on first try (takes about 3 mins) when it installs models, but it caches it so it's way faster the second time (also, it's available offline after it's cached haha) Works on any modern web browser It may be a funny little project, but it's genuinely taught me so much about WebML and Vision models, and the technologies we're getting with WebML will 100% dem...

Show HN: Undetectag, track stolen items with AirTag https://ift.tt/LviWMKG

Show HN: Undetectag, track stolen items with AirTag I developed a device that turns an Airtag on and off at specific intervals. Current Airtags are detectable right away and cannot be used to track stolen property. That device allows you to hide an Airtag in your car, for example, and someone that steals your car will not be able to use some app to detect it. The Airtag will also not warn the thief of its presence. After some hours, the Airtag turns on again and you can find out its location. It’s not foolproof, as the timing has to be right, but still useful. What do you think? https://undetectag.com/ May 15, 2025 at 10:46PM

Show HN: Family Folder – Help your family remember everything, organise anything Hi Show HN, I’m both nervous and excited to share what I’ve been working on in the early mornings and late evenings over the past few months: Family Folder – a tool to help you and your loved ones stay connected, simplify planning, and never miss a moment. This is mostly a solo project—though I’ve leaned on ChatGPT and Upwork when I hit the limits of my technical skills. I love learning, and this has been a crash course in programming, DevOps, design, UX, and everything in between. The idea came directly from my own experience: trying to keep on top of family life, from newborns to supporting my mum’s memory, birthdays, childcare logistics, and where the insurance documents are stored. Existing tools felt too generic, too corporate, or too messy. I wanted something built for families. Stack: • Ruby on Rails 7 (via Jumpstart Pro) • PostgreSQL • Hosted on Heroku (EU region) • S3 (EU) for file uploads • (Comi...

Show HN: Doxxer – CLI tool for dynamic SemVer versioning using tags https://ift.tt/wVu08gL

Show HN: Doxxer – CLI tool for dynamic SemVer versioning using tags Hi, first time poster here! Wanted to share a small CLI utility in Rust: doxxer! It is a tool for working with Git repositories, more specifically, extracting and calculating current/upcoming semantic versions for your repo's tags. It is heavily inspired by the output from "git describe --tags". Why use anything else then? The output is not fully SemVer compliant and therefore I was modifying it in all my projects separately, which I wanted to avoid. Single binary, single predictable output. It does not currently have pre-built binaries, so you have to install it via cargo, but it's in the roadmap! https://ift.tt/S4BtDy7 May 14, 2025 at 10:10PM

Show HN: LTXV 13B Distilled – Generate 5s Videos in Under 10s https://ift.tt/By8cxSH

Show HN: LTXV 13B Distilled – Generate 5s Videos in Under 10s Hey HN, after our 13B release we've been working on a faster version of our open-source video model and we're excited to share it. We started with a 13B base model that already had competitive generation speeds (e.g. 55s for a 5s video on an H100 — faster than any other model out there). But we wanted to push it further to allow everyone to quickly iterate over their video generations. So we built a distilled version focused on speed without sacrificing temporal or spatial coherence. With the Distilled model, you can now generate 5-second 720p videos in about 9.5 seconds on an H100, and around 1.5 minutes on a consumer GPU like an RTX 5090. Because the base and distilled models are interoperable, you can mix and match them in a single rendering pipeline. That gives you three modes: - Distilled Pipeline: Fastest. Uses just 4–8 steps end to end. Ideal for rapid iteration and experimentation (~9.5 seconds on H100, ~1.5 ...

Show HN: Helixdb – Open-source vector-graph database for AI applications (Rust) Hey HN, we want to share HelixDB ( https://ift.tt/TKC02FS ), a project a college friend and I are working on. It’s a new database that natively intertwines graph and vector types, without sacrificing performance. It’s written in Rust and our initial focus is on supporting RAG. Here’s a video runthrough: https://ift.tt/6xPFTRw . Why a hybrid? Vector databases are useful for similarity queries, while graph databases are useful for relationship queries. Each stores data in a way that’s best for its main type of query (e.g. key-value stores vs. node-and-edge tables). However, many AI-driven applications need both similarity and relationship queries. For example, you might use vector-based semantic search to retrieve relevant legal documents, and then use graph traversal to identify relationships between cases. Developers of such apps have the quandary of needing to build on top of two different databases—a vect...

Show HN: Lumoar – Free SOC 2 tool for SaaS startups We built Lumoar to help small SaaS teams get SOC 2-ready without paying thousands for Big 4 consultants or dealing with bloated compliance platforms. As a startup ourselves, we faced the usual issues: long security questionnaires, confusing audit requirements, and expensive tools that felt overkill. Lumoar is a simpler alternative: - Generate compliant SOC 2 policies automatically - Track your controls and progress in a clean dashboard - Upload evidence and get plain-language recommendations - Designed for engineers and founders, not compliance pros It's free to start — you can generate policies and explore the dashboard without a sales call or demo. Would love to hear what blockers you’ve faced with SOC 2 and what other frameworks you’re thinking about (e.g., ISO 27001, GDPR).

Show HN: AI-powered batch photo editor for real estate photographers I got tired of repetitive editing tasks, so I built a tool that simplifies bulk edits using text prompts and AI workflows. Now I can quickly handle things like virtual staging, changing backgrounds, adding/removing objects, adjusting brightness and exposure, color corrections, boosting contrast and clarity, fixing distortions, batch color grading and much more! But most importantly, I can do this to all selected images, tens, hundreds or more. I'm particularly interested in feedback on the workflow and UI from photographers/editors who handle large volumes of images. I've increased the free plan credits to 40 so you can edit up to 40 images, if you'd like to help me trial it out. Otherwise I'm happy to answer any questions about the implementation or roadmap. https://4ditor.com/ May 9, 2025 at 08:08AM

Show HN: Miralis – a RISC-V virtual firmware monitor https://ift.tt/NR6hDcd

Show HN: Miralis – a RISC-V virtual firmware monitor Miralis is a RISC-V firmware that virtualizes RISC-V firmware. In other words, it runs firmware in user-space (M-mode software in U-mode). The fact that this is even possible is interesting: indeed, not all ISAs are virtualizable, and the same applies for their firmware mode. It all boils down to the virtualization requirements [1], which is a great read if you haven't come across it yet. Arm's EL3 cannot be virtualized, for instance, because some instructions, such as `cpsid`, are sensitive but do not trap (`cpsid` is a nop in user-space). If you have a VisionFive 2 or a HiFive Premier P550, you can try it out, the instructions are in the documentation [2, 3]. Of course, it runs on QEMU too. As Miralis is a research project, we have also been using it as a vehicle to explore other research ideas, such as automated verification of hypervisors [4]. For instance, we verified instruction emulation by comparing Miralis' imple...

Show HN: Hydra (YC W22) – Serverless Analytics on Postgres Hi HN, Hydra cofounders (Joe and JD) here ( https://www.hydra.so/ )! We enable realtime analytics on Postgres without requiring an external analytics database. Traditionally, this was unfeasible: Postgres is a rowstore database that’s 1000X slower at analytical processing than a columnstore database. (A quick refresher for anyone interested: A rowstore means table rows are stored sequentially, making it efficient at inserting / updating a record, but inefficient at filtering and aggregating data. At most businesses, analytical reporting scans large volumes of events, traces, time-series data. As the volume grows, the inefficiency of the rowstore compounds: i.e. it's not scalable for analytics. In contrast, a columnstore stores all the values of each column in sequence.) For decades, it was a requirement for businesses to manage these differences between the row and columnstore’s relative strengths, by maintaining two separa...

Show HN: Cutting the Fat from Stream Processing: Meet ZephFlow (Open Source) Hey HN, Apache Flink is a beast for heavy-duty stream processing – no doubt about it. We've used it, admired its power, and it heavily influenced our thinking. But let's be honest: for a lot of common, everyday stream processing tasks, Flink (and similar frameworks) can feel like bringing a bazooka to a knife fight. The operational overhead and complexity for simpler, stateless jobs often outweigh the benefits. That's why we built ZephFlow. What is ZephFlow? ZephFlow is a stream processing framework built for lightweight operations and simplicity. It distills the core principles of high-performance, low-latency data processing but specifically targets stateless or simpler stateful workloads. This focus allows ZephFlow to be significantly more lightweight and easier to operate compared to more comprehensive platforms like Apache Flink. A single ZephFlow job can run as a lean, efficient process, maki...

Show HN: Cloi – free local debugging agent in your terminal Hey everyone! For the past two weeks my friend and I have been heads-down building Cloi, a fully local debugging agent that runs right in your terminal. You probably know the drill—every AI coding tool asks for API keys, subscriptions, and uploads your entire codebase to the cloud. Cloi does none of that: it runs entirely on your machine, with no cloud, no API keys, no subscriptions, and zero data leaving your system. What Cloi does: - Contextual error capture: Grabs your stack trace, local files, and environment to understand the issue. - Local LLM inference: Spins up Ollama on your box and generates targeted fixes—no external servers. - Safe patch application: Presents you with diffs and only applies changes when you explicitly approve. - Model‐agnostic: Ships with Phi-4 out of the box (surprisingly capable for its size!), but you can swap in any Ollama model you’ve installed. Why we built it: - Maintain full control over yo...

While working on a project that involves frequently parsing a lot of feeds, I needed a fast JavaScript-based parser to extract specific fields from feed namespaces.

Feedsmith supports all feed formats and many popular namespaces, including: Podcast, Media, iTunes, Dublin Core, and more. It can also parse and generate OPML files. I am currently adding support for more namespaces and feed generation for RSS, Atom and RDF.

Show HN: I built a synthesizer based on 3D physics and launched the product I've been working on the Anukari 3D Physics Synthesizer for a little over two years now. It's one of the earliest virtual instruments to rely on the GPU for audio processing, which has been incredibly challenging and fun. In the end, predictably, the GUI for manipulating the 3D system actually ended up being a lot more work than the physics simulation. So far I am only selling it direct on my website, which seems to be working well. I hope to turn it into a sustainable business, and ideally I'd have enough revenue to hire folks to help with it.

Show HN: Sriracha Imageboard and Forum A read-only demo[0] of Sriracha's output is available. Screenshots of the management panel are also available in the demo. Sriracha allows anyone to host an imageboard or forum using Go. Sriracha has full support for custom templating. Standard .gohtml templates are included, and site owners may specify a directory where any custom templates of the same name will override included templates. Sriracha makes use of Go's plugin support to implement a plugin system[1]. This allows site owners to customize their installations without making changes to Sriracha itself. 0. https://ift.tt/BVrFUKz 1. https://ift.tt/BLS23w8... https://ift.tt/4AmRVqQ May 1, 2025 at 11:56PM

Show HN: Robot Unlock – an open-ended programming game/zachlike https://ift.tt/fhqYDpG

Show HN: Robot Unlock – an open-ended programming game/zachlike Hello, In 2010 I made an open-ended programming game based on Befunge and Brainf*k. I was young and didn't know what I was doing - coding it in AutoIT of all things and using borderless windows for sprites. Nevertheless, it was a full game and some people actually played it, sharing solutions with each other. I took it as a sign that the game had some potential - I appreciated this very much at the time. It was zachlike at its core, except that it came out earlier than SpaceChem and the term hadn't been coined yet. Years passed, I worked in the game industry, had some fun, learned a few things and eventually burned out. Meanwhile, Zachtronics kept making games and managed to define a genre, proving that there indeed was a market for such games. I'm very happy about that. Now I want to have a shot at going indie and almost 15 years later I'm launching the sequel to my 2010 game. One of my playtesters has bee...

Show HN: Runnem – A CLI to manage local services with screen and YAML https://ift.tt/QP5EKd6

Show HN: Runnem – A CLI to manage local services with screen and YAML Hi all! This is my second ever Show HN post, my first was back in 2020. I built runnem, a CLI for managing local services in projects with multiple components like frontend, backend, and database. I have a few projects going at once, each with several services. When I come back to one after a few weeks to fix a bug or make a change, I always forget how to spin everything up. Which command runs what? What depends on what? runnem solves that for me: - runnem up and runnem down to start or stop everything - Handles service dependencies automatically - Uses screen under the hood (I'm keen on screen) - Manages logs, rotates them, and cleans up ports - Simple YAML config per project (runnem.yaml) I didn’t research alternatives deeply. I’ve used Tilt before, mainly with Docker, but wanted something lightweight and terminal-native for projects with mixed stacks. Also, did I mention that I like screen? :) I haven’t tested...

How the 1906 Earthquake Transformed Our Public Transit System

How the 1906 Earthquake Transformed Our Public Transit System By Jeremy Menzies April 18 marked the anniversary of the 1906 Earthquake and Fires. This disaster destroyed much of San Francisco and displaced over 50% of the residents. It also ushered in a new era of public transportation in the city. Before the quake: Cable cars rule downtown   Before the earthquake, cable cars dominated transit in downtown San Francisco. Cable cars first started running in 1873. By the mid-1890s, cable car lines extended from the Ferry Building to Golden Gate Park. Cable cars are pulled along the street by an underground cable. This movement is possible thanks to a network of pulleys... Published May 01, 2025 at 07:00AM https://ift.tt/Njkbgm5
