Show HN: The classic Minesweeper on an irregular grid
I'm experimenting game mechanics that are usually seen on a typical grid, but transposed on an irregular one.<p>This is a first game based on Minesweeper.<p>The changes an irregular grid brings are that cells don't all have 8 neighbors. Some can have less, some can have more. So when you try and deduce if a tile has a mine, you have to pay closer attention at the number clues and which tiles neighbors it.<p>My intention is to make a very classic game a bit more challenging & fun.<p>I've also released a first version of Checkers/Draughts, and plan to test similar variants for Chess, Othello and Go.
Show HN: Stanchion – Column-oriented tables in SQLite
Hello HN!<p>I built stanchion to scratch my own itch. I have personal applications running on SQLite where I want to store log and metric data (basically forever) but don't want to add complexity by bringing in a new database or whole separate server. Some of these applications are running on a Raspberry Pi, where storage and compute are limited, but I still want data warehouse like capabilities.<p>I envision stanchion being used in similar scenarios: on phones and resource-limited devices in applications that are already using SQLite. I know that there are alternatives like DuckDB (which is very cool), but I want stanchion to be "good enough" that it is useful without having to add whole new database technology.<p>If you think stanchion may be a good fit for your use case and you are interested in contributing, please test it and provide feedback by opening issues for any bugs, difficulties, or missing features you would need! Ideas are also welcome in this thread or as a github issue. Of course stars are always appreciated as well. The CONTRIBUTING doc in the repository has more details.<p>- Dan

Show HN: Open-source x64 and Arm GitHub runners
Ubicloud is an open source cloud. Think of it as an open alternative to cloud providers, like what Linux is to proprietary operating systems. You can self-host Ubicloud or use our managed service.<p>Our first use-case is GitHub Actions. We support x64 and arm64 Linux runners; and reduce your Github Actions bill by 10x. We can give you hardware similar to default GitHub runners because of the very high margins on the cloud. One difference with our hardware is that we use local NVMes for better disk performance.<p>Ubicloud and our GitHub Actions integration is also open source. You can check out our integration here: <a href="https://github.com/ubicloud/ubicloud/blob/main/routes/web/webhook/github.rb">https://github.com/ubicloud/ubicloud/blob/main/routes/web/we...</a><p>For security and isolation, we give you a clean and ephemeral VM for each job. When the job completes, we deprovision the VM and wipe out the block storage device attached to the VM. We set up your firewall rules to lock down access to the VM; and also encrypt your data at rest and in-transit.<p>(We use Linux KVM and the Cloud Hypervisor as our underlying VM tech. For our block device, we use and extend SPDK: <a href="https://www.ubicloud.com/blog/building-block-storage-for-cloud-with-spdk-non-replicated">https://www.ubicloud.com/blog/building-block-storage-for-clo...</a>)<p>Ubicloud runners are also fully compatible with GitHub runners. To get started, all you need to do is change 1-line in your workflow file. Each account gets 1,250 free build minutes per month with standard-2 runners.<p>We’d love to hear your feedback!<p><a href="https://www.ubicloud.com/docs/github-actions-integration/quickstart">https://www.ubicloud.com/docs/github-actions-integration/qui...</a>

Show HN: Phrasing – learn every language, to any level
Hey there HN -<p>Today I'm sharing a demo of my our language learning tool, Phrasing. It's a tool born from the language acquisition hypothesis, too many hours in an anki slog, and a strange desire to always be learning obscure languages.<p>The method is simple:<p>1. type in a show<p>2. learn the most important words<p>3. watch the show/acquire the words<p>4. review the words when needed in the future.<p>On top of that, we're trying to:<p>- do some novel things with spaced repetition (no more anki slog)<p>- expand the sort of content you can learn from (I want to to refresh my French by reading The Stormlight Archive)<p>- make an insanely beautiful tool for all languages (I want to learn Sanskrit and Hawaiian and such)<p>I think we're off to a great start so far, and I'm happy to be able to share what we have already! We've taken some of our core features, and ripped them out to put them on a playground for HN to explore. There's so much more to come though, this is just the beginning.<p>I'll be here all day to answer any questions. Thanks for checking it out and have a wonderful day <3<p>EDIT: This link was meant as a demo so hacker news has something to click around on (as per the rules of Show HN). The main marketing page can be found at <a href="https://phrasing.app/" rel="nofollow">https://phrasing.app/</a> - I think that's causing some confusion

Show HN: Boardzilla, a framework for making web-based board games
Show HN: Boardzilla, a framework for making web-based board games<p>Tldr: We’ve made a framework for web-based board games. You can try out some games over at <a href="https://boardzilla.io" rel="nofollow">https://boardzilla.io</a>, or you can take a look at <a href="https://docs.boardzilla.io" rel="nofollow">https://docs.boardzilla.io</a> to learn more about how to develop your own game. Source is available at <a href="https://github.com/boardzilla">https://github.com/boardzilla</a><p>Hey y’all. My brother and I have made a framework for board games. During the pandemic we started to look at BGA but got discouraged by how old-fashioned the tools were and how cumbersome the development process was. We set out to make our own framework where you could use the same code for both the client and server. Our hope is anyone familiar with Typescript and CSS could code up a game without worrying about state management, persistence or networking.<p>It’s still very much a wip, and we're rapidly adding features and games. But we’ve got our first draft of developer docs done, and we've put up a few games we've developed to showcase and test out the platform. Source for the games and framework is available on Github, and we’re excited to code more games and hopefully encourage other people to try it out. Happy for any feedback.

Show HN: Anki/Duolingo-like app using educational YouTube videos
Hi HN,<p>I watch A LOT of educational YouTube videos but wasn't forgetting a good chunk of the details because I was only really passively watching. So I made a tool that generates quiz questions/flashcards from YouTube videos, and uses spaced repetition like Anki or Duolingo to keep it in memory.<p>Let me know if you find it cool/useful (or terrible ) or if you want to know a bit about the details!

ZX Spectrum Raytracer
Inspired by a recent article in HN about raytracing on some ancient architecture, I realized that I've implemented many a raytracer in my life, but never one for my first love, the ZX Spectrum. So I fixed the glitch.<p>Trigger warning: the source code includes GO TO statements. Because that's how we did it in the 80s! Enter at your own peril.
Show HN: Open-source Rule-based PDF parser for RAG
The PDF parser is a rule based parser which uses text co-ordinates (boundary box), graphics and font data. The PDF parser works off text layer and also offers a OCR option to automatically use OCR if there are scanned pages in your PDFs. The OCR feature is based off a modified version of tika which uses tesseract underneath.<p>The PDF Parser offers the following features:<p>* Sections and subsections along with their levels.
* Paragraphs - combines lines.
* Links between sections and paragraphs.
* Tables along with the section the tables are found in.
* Lists and nested lists.
* Join content spread across pages.
* Removal of repeating headers and footers.
* Watermark removal.
* OCR with boundary boxes
