Show HN: I made a tool to help collect and validate startup ideas
Hey HN, I’m Kyrylo. I recently created a small tool that lets you gather, refine, and validate SaaS/startup ideas using AI.
I used to jot down my product ideas in a note apps, but it wasn’t very practical for collecting feedback or refining them. So, I built this tool to make the process easier.<p>Here’s how it works:<p>1. Enter a brief description of your idea. 2. The app uses AI to generate project details. 3. Share your idea via a link that includes a feedback form.<p>It’s pretty straightforward, and I’d love to hear your thoughts or any suggestions!
Show HN: We made a tool to help developers improve OpenAPI specs
Hey, I'm Martyn and I recently joined Zuplo. OpenAPI is a huge part of what we do, but getting a document up to scratch out of the gate, especially if you're not super well versed in the actual specification and what you should use and when.<p>So we built a suite of tools to help with this called Rate My OpenAPI. It will score your OpenAPI document out of 100, as well as giving you individual scores in 4 key areas; completeness, SDK generation, security and documentation.<p>Along with the score, you also get details of what the issues, or errors are, as well as guidance on what they actually mean and why they're important.<p>We exposed the API for it using Zuplo, and then built a CLI, and a GitHub Action on top of that so that you can add Rate My OpenAPI into your workflow however you like.<p>You can check it out and use all of this right now, for free. I've already found it extremely useful and I hope you do to.<p>Feedback is absolutely welcome!

Show HN: Double – Design and invest in your own stock index
Hey everyone, we’re JJ and Mark from Double (<a href="https://double.finance">https://double.finance</a>). Over the past few months we’ve been working on an investing app that lets anyone design and invest in their own stock index.<p>Start by picking one or more strategies. You can find 20+ starting points in Double that vary from direct index versions of classic ETFs (like SPY) to strategies focused on specific industries, market trends, or themes (like YC public companies). You can also easily build your own grouping of stocks, and tilt your strategy towards or away from certain stocks or sectors.<p>Once you’ve chosen your portfolio, we run a daily portfolio optimization to determine what trades to make, which considers taxes, trading costs, drift and holding costs[1]. If your account is sufficiently diversified, we enable Tax Loss Harvesting as well to capture losses that can help offset capital gains[2]. Finally you can move between strategies either all at once or over time[3].<p>JJ started work on this after selling his last company, making some money, and growing really frustrated at the quality of the portfolio tools available to retail investors. Financial advisors have tools for direct indexing, tax loss harvesting and dollar cost averaging, but they generally charge upwards of 1% a year in AUM fees. Things like Parametric[4] and Canvas[5] have succeeded, but are only accessible through advisors. We wanted to build these kinda advanced portfolio tools for ourselves without any AUM fees.<p>Some common use cases we’ve found are diversifying away from a large RSU position or migrating between risk on and risk off strategies over time. You can also easily allocate a percent of your portfolio to specific baskets of stocks.<p>Let us know what you think! Feel free to email us at founders@double.finance as well<p>[1] More info about our optimizer here <a href="https://help.double.finance/en/articles/9718142-portfolio-optimization">https://help.double.finance/en/articles/9718142-portfolio-op...</a><p>[2] More info about out direct indexing tax loss harvesting here <a href="https://help.double.finance/en/articles/9718959-direct-indexing-tax-loss-harvesting">https://help.double.finance/en/articles/9718959-direct-index...</a><p>[3] More info about out dollar cost averaging here <a href="https://help.double.finance/en/articles/9718389-dollar-cost-averaging">https://help.double.finance/en/articles/9718389-dollar-cost-...</a><p>[4] <a href="https://www.parametricportfolio.com/" rel="nofollow">https://www.parametricportfolio.com/</a><p>[5] <a href="https://canvas.osam.com/" rel="nofollow">https://canvas.osam.com/</a>

Show HN: I've open sourced DD Poker
I'm the original author of DD Poker, a Java-based computer game that ran on Mac, Linux and Windows and originally sold in stores in physical boxes.<p>I shut down the backend servers in 2017 but the game is still functional and people can still play each other online even though the central lobby and find-a-game functionality no longer work.<p>I've been asked over the years to release the source code, especially during the pandemic, and again this year. I finally got motivated to clean up the code and put it out there.<p>The code is 20 years old and uses some ancient Spring, log4j, Wicket and other dependencies, but it still works on Java 1.8.

Show HN: SpecOS – A 64 bit OS kernel from scratch
I've been working on this for ~3 months now, with pretty slow progress to be honest. So far I've got an ATA PIO mode hard disk driver, a FAT32 file system, a real time clock driver, and of course the essentials (interrupts, keyboard, pixel graphics). Kernel panics also cause a blue screen of death xD. It uses a bitmap physical memory allocator, and I'm fixing some issues with paging at the moment as a work towards running userspace applications. I'd be interested to see your thoughts on it :D

Show HN: See the impact on your cloud costs as you code
Hey folks, my name is Owen and I recently started working at a startup (<a href="https://infracost.io/">https://infracost.io/</a>) that shows engineers how much their code changes are going to cost on the cloud before being deployed (in CI/CD like GitHub or GitLab). Previously,<p>I was one of the founders of tfsec (it scanned code for security issues). One of the things I learnt was if we catch issues early, i.e. when the engineer was typing their code, we save a bunch of time.<p>I was thinking … okay, why not build cloud costs into the code editor. Show the cloud cost impact of the code as the engineers are writing it.<p>So I spent some weekends and built one right into JetBrains - fully free - keep in mind it is new, might be buggy, so please let me know if you find issues. It is check it out: <a href="https://plugins.jetbrains.com/plugin/24761-infracost" rel="nofollow">https://plugins.jetbrains.com/plugin/24761-infracost</a><p>I recorded a video too, if you just want to see what it does:<p><a href="https://www.youtube.com/watch?v=kgfkdmUNzEo" rel="nofollow">https://www.youtube.com/watch?v=kgfkdmUNzEo</a><p>I'd love to get your feedback on this. I want to know if it is helpful, what other cool features we can add to it, and how can we make it better?<p>Final note - the extension calls our Cloud Pricing API, which holds 4 million prices from AWS, Azure and GCP, so no secrets, credentials etc are touched at all.<p>If you want to get the same Infracost goodness in your CI/CD, check out <a href="https://www.infracost.io/cicd">https://www.infracost.io/cicd</a>
