Show HN: Mental Models for Startup Founders Hello HN, I launched Wingify/VWO (Visual Website Optimizer) here on HN in 2010. The initial momentum and feedback I got from this place was a key reason I was able to profitably bootstrap the company to roughly ~$30MN ARR. Over the last 2 years, I have been writing a book for startup founders that's informed by my experience with Wingify and many failed attempts before it. It's finally done, so thought of launching it on the same forum where it all started for me :) There are a total of 68 mental models covering various aspects of building a startup: - Choosing markets - Building products - Ecosystems and partners - Thinking about Moats - Approaching marketing - B2B v/s B2C - Hiring & culture Unlike other books, I'm not sharing my story and neither take a very prescriptive approach. Rather, I use mental models to shine light and provide a tractable way of looking at problems an entrepreneur encounters during her startup. I und

I’ve been lurking on HN for around 2 years while working on this project seeing people post amazing HN reader apps of their own. I’ve always figured Hazumi wasn’t good enough yet to post here but if I wait around until I’m ready, I’ll probably never share so here goes… Hazumi is a modern Hacker News app for your pocket with some intentional limitations. Stories are displayed on a simple colourful card, with images, that condenses all the information you need at a glance. Out of the box you get accessibility features for system settings like light/dark mode and text size. Others are controlled in app for opening stories in a Web View vs externally via Safari, defaulting to Reader Mode and reducing animation bounciness.

Show HN: Blotter – An interactive, never ending music video One day I was listening to a playlist and wished there could be some cool visuals to go along with it. Blotter is a proof of concept I hacked together that does a bit of audio recognition combined with a few generative AI models (both text and img) to create visuals that are relevant to the song. The video stream is generated in real time at 24fps - you can try it yourself by requesting visuals in the Twitch chat using the "!v" command! Right now it's mostly a fun hack project, but I am tinkering with new model architectures for higher fidelity video as well as an interactive tool so people can make videos with their own audio files. I'd love to hear any feedback or suggestions, thanks! https://ift.tt/w3zEYOy May 23, 2023 at 04:21AM

Show HN: Psychic - An open-source integration platform for unstructured data My cofounder and I used to work at Robinhood where we shipped the company’s first OAuth integrations, so we know a lot about how data moves between companies. For example, we know that the pain of building new API integrations scales with the level of fragmentation and number of competing "standards". In the current meta, we see this pain with a lot of AI startups who invariably need to connect to their customers data, but have to support 50+ integrations before they even scale to 50+ customers. This is the process for an AI startup to add a new integration for a customer: - Pore over the API docs for each source application and write a connector for each - Play email tag to find the right stakeholders and get them to share sensitive API keys, or give them an OAuth app. It can take 6+ weeks for some platforms to review new OAuth apps - Normalize data that arrives in a different formats from each sour

Show HN: Horizon – Programmatic Prompt Generation and LLM Configurations Hi HN. I heard you like dev tools and AI, so we wanted to share our project that we’ve been working on. We’re working on Horizon [1] - a higher level abstraction for LLMs so that developers can spend less time trying to grapple with LLMs to make them work and more time with users. This is the starting feature set which takes an auto-ML approach to identify the optimal LLM model, hyperparameters, and prompt - instead of just giving you the tooling to figure it out yourself. You can read more about it in our documentations. Our view is that as LLMs become increasingly commoditized and prompts become easier to develop all the while fine-tuning is not realistic for the many organization out there - the configuration, optimization, and management will become much more difficult at-scale (consist with Andrej’s recent post [3]). The idea came as we were trying to build LLM apps (think sales outreach, ppt generation, supp

I created this lib in the need of a simple and tiny framework to easily do AJAX-style navigation / replacement of fragments in the page, in a web application. For people who don't want to use client-side-rendering and complex frameworks à la React, there are nowadays a few "HTML-over-the-wire" libraries, like HTMX, Unpoly or this super-tiny one Swap.js :) One other key thing is that no external tool is needed: no bundler, no webpack, no TypeScript compiler, no minification needed. Just write HTML, JS (+ your preferred server-side language: PHP, Python, etc.) and it works. The framework makes use of fetch (of course) but also MutationObserver API to be able to launch actions when parts of the DOM change.

Show HN: Localias, securely manage local devserver aliases Hey HN, Localias is a new tool that you can use to securely manage your local development servers. Use localias to securely proxy a local development server running on http://localhost:3000 and access it at https://frontend.test . Localias is built on top of Caddy, so it's secure and performant. And because it's built on top of Caddy, it will automatically generate and install a custom root certificate, and automatically generate and sign certificates for each of your aliases. This all works by editing your /etc/hosts file and generating a Caddy config, then running the proxy server for you either in the foreground or as a daemon. It's easier to deal with than running Caddy yourself. Your whole team can share a configuration file in your git repo, making it easier to share URLs with each other while developing. I hope you try it out and find it useful! The code is MIT-licensed and I'm happy to accept any feedbac

San Francisco To Extend Parking Meter Hours Citywide By Pamela Johnson Much like real estate, parking is at a premium in San Francisco. For decades, most parking meters in the city have operated from 9:00 a.m. until 6:00 p.m. Monday through Saturday. While drivers generally love free parking, they may not realize that it’s hard to find a space in the evenings and on Sundays in many neighborhoods because the meters are not running.  Beginning in July 2023 and continuing in phases through December 2024, the SFMTA will extend parking meter hours until 10:00 p.m. Monday through Saturday and add Sunday meter hours from 12:00 p.m. until 6:00 p.m. Parking meters already operate in the evenings or on Sundays in some areas, including Mission Bay, South Beach, the 18th Street business district in Potrero Hill and along the Embarcadero. This extension will make meter hours more consistent citywide, create more parking availability and generate revenue to help the agency sustain vital Muni ser

Show HN: Capillaries: Distributed data processing with Go and Cassandra I started thinking about this approach after working on a large-scale project for a major financial company where our group developed a distributed in-house data processing solution. On a regular basis, it ingested a few gigabytes of financial data and, within a tight SLA time limit, produced a lot of enriched/aggregated/validated data for a number of customers. Sometimes, source data had errors, so operators with domain knowledge had to verify data validity at some checkpoints, immediately make corrections, and re-run parts of the workflow manually. The solution involved complex web service orchestration, custom database and was very demanding on the infrastructure availability. Capillaries is a built from scratch, open-source Go solution that does just that: ingests data and applies user-defined transforms - Go one-liner expressions, Python formulas, joins, aggregations, denormalization - using Cassandra for inte

More than simply a way to get from point A to point B?   A subway is much more when people put their hearts and souls into building it, as so many who worked on the recently opened Central Subway did.

Despite the relative lack of optimization, I'm very pleased with the performance so far - although I haven't done a huge amount of benchmarking, it seems to be significantly faster than the stock Lua 5.4 interpreter for the quicksort test, and the btrees test (copied from the Computer Language Benchmarks Game).

Show HN: Oneleet – Penetration Testing for SOC 2 and beyond Hello HN, Over the past months at Oneleet (YC S22), our team has been building https://app.oneleet.com , a compliance-focused pentesting-as-a-service platform. It allows companies to easily schedule and manage penetration tests, designed for both compliance and security enhancement. We collaborate exclusively with top-tier vetted penetration testers based in NATO countries, ensuring superior quality results. Competitors like Cobalt work with just about anyone, of which they put multiple on a single engagement to ‘average out’ the quality. Despite their efforts, it is still hit-and-miss. By being very selective about who we work with (many Cobalt pentesters don’t make the cut), we are very consistent in the level of insight and quality we provide. Our team puts a lot of work into making sure that pentest results can be leveraged beyond security improvements. We are fully aware that with the current SOC 2 craze[1] most companies

Show HN: Deterministic objective Bayesian inference for spatial models [pdf] To give some context, objective Bayesian inference refers to Bayesian analysis (i.e. integrating over the parameter space) using a prior that is design to represent "minimal information" (see [1], [2], and [3] for an overview). Particularly in cases where a model's likelihood function is not strongly peaked about a point, objective Bayesian inference can give better results than methods based off of point estimates like Maximum Likelihood [4]. Reference priors provides a general approach to construct so-called noninformative priors that are suitable for Objective Bayesian analysis ([5], [6]). The approach takes a practical viewpoint of noninformative priors and looks to build priors that are both tractable and provide good performance on frequentist coverage simulations. See Section 2 for a description of how the process and frequentist simulations work and [7] for examples with some basic models

Meet the People of the Next Generation CIS: Leon Yu By Deanna Leo Leon Yu, Graphic Artist, Creative Services   What do you do on the project?  I help design the user experience: What users see on the new displays, how they see it and how often they see it, down to the actual graphics.   How do you feel your work impacts our customers? Who will benefit?  My work communicates transit information to customers as cleanly and clearly as possible, so the information is easy for any member of the public to understand. We only have a small space to work with on the displays, so we must make it count. People  of all backgrounds, languages and abilities, so need to get this information quickly at a glance.   What was your favorite part of the project?  My favorite part is working with the team and all the different CIS systems. This is such a multidisciplinary project involving many staff and people I’ve never worked with before. Being able to collaborate with so many dedicated colleagu

Show HN: Build progressively enhanced reactive HTML apps using Go and Alpine.js Fir leverages Golang’s standard library html/template package and a bit of alpinejs to allow building reactive UIs. You start with plain old html and use alpinejs to enhance it to bring no-page-reload interactivity to web apps. The Fir toolkit is designed for Go developers with moderate html/css & js skills who want to progressively build reactive web apps without mastering complex web frameworks. It includes a Go library and an Alpine.js plugin. How it works ? On receiving user-interactions the fir server re-renders html templates and sends it over the wire where the fir client library selectively updates the changed areas. When a user event is received by a Fir route, an array of html templates are rendered on the server and returned as an array of DOM events to the browser. The DOM events are consumed by the alpinejs plugin and dispatched within the DOM where listeners attached to elements can use th

Show HN: Card game where players write their own cards that get parsed into code Wordbots is a long-running side project I've been working on on-and-off for the past ~7 years that I finally feel comfortable enough with to share with the HN community. It's an online tactical card game (inspired by games like Hearthstone and Magic: the Gathering), where players write their own cards in natural language, that gets parsed down to JavaScript. The English-to-JavaScript translation is handled by a semantic parser operating on a hand-crafted CCG grammar – kind of an “old-school” approach in this age of LLMs but one that performs quite well on the very constrained language of Wordbots cards. The resulting game gets pretty wacky as players can create all sorts of cards, though there are some game formats that try to produce more balanced gameplay as well (e.g. one format in which both players shuffle their decks together, and various draft formats). If you're curious about how it all

Show HN: Spiti – Private video library for high-performing teams Hi HN I’m Therese, one of the founders of Spiti. My co-founder, Sai, and I are thrilled to launch Spiti to the HN community! We’ve been working on a better way for teams to organize, access, share, and collaborate on internal videos. Recently, we built the ability to record, too. It is built specifically to enhance remote and hybrid teams’ access to internal knowledge and context lost in historical conversations. ------- *tl;dr backstory:* We’ve worked in start-ups and larger companies. In our previous stints, searching for stuff took up a lot of time. Tooling solved for better access and collaboration in most cases, except videos. Recorded meetings, webinars, product demos, explainer videos, customer conversations, etc. were always scattered around in various folders on the cloud, links in emails, and Slack. But those videos are important, and easy access would save the team and us at least a few hours every week. ------

Show HN: Interactive Git Training Use Cases Hello, I have been working for years with junior developers and I find that many of them struggle to get out of some "delicate situations". Example "detached head", "wrong rebase", "for some reason I see duplicate commits" and so on. To help my colleagues I came up with a list of git uses cases that can be tested in a sort of interactive playground using a shell script that will set-up the use case and then we can go ahead and try to solve the problem. The main advantage here is that all use cases are reproducible and that by looking at the shell script we can see how we got in the mess in the first place. Everything is written in posix shell and should work on linux, macos and windows (with git bash). Any comments, feedback and contributions are very welcome !

Show HN: Cptn.io – open-source integration platform Hi, I am Krishna Thota. I am building an open source integration and data platform( https://cptn.io ). The product is MIT licensed and the repo is at https://ift.tt/I6fyOQD . I have started on my startup journey an year ago and launched a monitoring platform called DevRaven. Unfortunately the product did not takeoff as expected. That story is for another day. But during the course of building the product, I have built several integrations leveraging MQs and Cloud Functions. While building and deploying Cloud Functions for happy paths is easy, I had to monitor logs for failures, build retry mechanisms or manually process failed events, keep instances running to prevent cold start timeouts. It can also get expensive with charges for MQs, server time for running cloud functions etc and costs can be unpredictable. I thought of building a platform where I can build integrations quickly, have the ability to look at incoming/outgoing events,

Show HN: Automatic Domain Verification The Domain Verification protocol stores a DNS TXT record at a DNS name derived from a hashed "verifiable identifier" (email, telephone, DID), enabling anyone that can prove control over the verifiable identifier to prove authority for the domain name, whilst preserving the privacy of the authorised party. Once setup, the record enables automatic domain verification for any service provider. This record could be automatically setup by domain registrars upon domain registration (with registrant opt-in) creating a fast lane for verification with service providers many new small businesses use (eg Google Ads, Facebook, Office365, Dropbox, etc). ===== Quick sidebar: This was originally submitted to HN under the title "Show HN: Make domain verification as easy as verifying an email or phone number" 3 days ago [1].

Show HN: Play SineRider, a math puzzle game built by teenagers at Hack Club Messing with your TI-84 graphing calculator is a rite of passage for every teenager who has ever been bored in a math class. In 2013 I was that teenager, and it gave me an idea for a tiny game about sledding on graphs. This project grew into my white whale, and I spent my twenties trying and failing to finish it alone. I shelved the game when I started working for Hack Club in 2018—until last May, when a few community members took it off the shelf and the project took on a life of its own. After a year of nights and weekends from a global team of 20+ teens from 8+ countries, SineRider enters public beta today! SineRider is literally an infinite universe of function composition puzzles, each with infinite solutions, that range from welcoming for 9th graders to difficult for even the most serious matlab user. And every day we tweet out a fresh one to be solved with your morning coffee. We hope you enjoy playing S
