Show HN: Bash Dungeon – An educational dungeon crawler in the shell
This is still WIP, but if anyone is interested, we could develop it much faster and perhaps even with cooler features like TUI graphics etc ...<p>Right now it is all in plain ol bash
Show HN: Foorr – A minimal to-do app with social accountability
I've created Foorr, a minimal to-do list app that focuses on short-term getting-things-done and the option to do this with friends by holding each other accountable and helping each other grow together. Main goal is to fuel your progress whatever needs to be done and hold yourself accountable for your own progress (with some external motivation).<p>Here's what it does:
- Create tasks for today and tomorrow only (real hyperfocus on short term GTD).
- Invite friends to cheer each other moving forward.
- Building up a daily streak as you finish all tasks daily. All tasks completed before midnight which were planned for that day, earns you a level up. Rewarding that sense of completion.<p>Why I built it:
I used physical post-it notes and was a bit done with it. I really wanted something minimal focusing only on my to-do's for today and tomorrow.<p>No bloated features, nothing to fancy/polished, just something no-nonsense I wanted to use myself. It might be useful for others who struggle with procrastination and keeping op progress getting things actually done. Feedback is definitely welcome and nice to hear if this resonates with anyone else.

Show HN: I made shopping clothes online easier
Hey HN,<p>A pattern I realized when I shopped for anything online is that by the end of my shopping session, I would accumulated over 15+ tabs. It's so easy to click on "Open in New Tab" that I figured other people have this issue as well.
Show HN: I made a game for learning the country flags of the world
I have always loved geography, and due to my childhood interest in football, I learned a lot of country flags.<p>A lot, but not all of them!<p>So, I decided to make a free game for anyone who enjoys flags and wants to improve their knowledge. You can compete against others because each game is timed.<p>Have fun!

Show HN: SQL Explorer – Open-source reporting tool that Just Works
I have been working on SQL Explorer, an open source, Django-based reporting and query tool for (gulp!) almost ten years. It's a tool that fits just right for me and many others, and I love and use almost every day. Write SQL, share results, do some analysis, get insight. No surprises.<p>A live demo instance is here (no login or anything required):<p><a href="https://demo.sqlexplorer.io/" rel="nofollow">https://demo.sqlexplorer.io/</a><p>And here's a fairly unprofessional, but very enthusiastic, video tour:<p><a href="https://sql-explorer.s3.amazonaws.com/Sql+Explorer+5.mp4" rel="nofollow">https://sql-explorer.s3.amazonaws.com/Sql+Explorer+5.mp4</a><p>The UI is constrained enough that there's very little to learn, while there is still a surprising amount of functionality and flexibility to address a lot of use cases.<p>Some of the stuff I'm excited about in the latest version:<p>- Intuitive and obvious integration to ChatGPT / the AI API of your choice. Doesn't purport to be 'magic'. Good prompting + relevant table scheme & data automatically injected into the prompt.<p>- Create a new connection by uploading a CSV or SQLite DB as a new connection, and it's instantly queryable. CSVs are parsed, types inferred, and a SQLite DB gets created (persisted to s3).
- New and improved SQL editor with strong autocomplete (based on your schema), and some fancy keyboard shortcuts.<p>Some of the old stuff that is still great:<p>- Pivot tables in-browser, so you don't have to open results in Excel for basic analysis. Unique URLs make everything shareable.<p>- Expose queries (optionally) as JSON endpoints. Great for prototyping APIs and scripts.<p>- All of the stuff you'd expect in a reporting tool (email reports, logging, favorites, exporting, etc.)<p>Hope you enjoy!

Show HN: I’ve made a cheaper SEO research tool
In the last 13 months I've spent total $1297 for Ahrefs subscription. Sounds like a little too much so I've build my own Keywords Research tool - Telescope.<p>While building it my total bill was $51 for 2 months and 41k+ keywords found. Every page of keywords costs $0.03 - $0.05. 2 payment options - usage-based subscription or just top up your balance with the amount you'd like to.<p>Telescope includes a couple of things:<p>- Keywords Explorer - finding keywords based on seed phrase and filters<p>- Keywords Ideas - keywords on interception on provided keywords<p>- Ranked Keywords - keywords a domain you specified with their positions and change since last DB update<p>- Saved Keywords - to store found keywords and plan the SEO strategy<p>I've put a lot of love into it and would love to get some feedback. IMPORTANT: every new account gets some free balance to start with. Appreciate it!

Show HN: I built a full-text search for your browsing history
Hi, I’m Peter, co-founder of Browspilot.<p>I built Browspilot, a minimalistic tool, to help you recall anything you have ever seen online using any clues you remember, or just scroll through your past activity.<p>Browspilot is perfect for popping up pages you use a lot but don’t want to keep open all the time or digging up stuff from way back. Whether you’re a student researching papers, a professional balancing multiple projects just type in what bit you recall in the moment, and boom, it’s there.<p>Looking ahead, we’re excited to take search to the next level. We’re working on features that’ll let you integrate and search across different apps and find things based on meaning—including images—using advanced vector search techniques.

Show HN: Open Sourcing Our No-Code WebXR Editor After 5 Years of Development
Transfer Thought is a No-Code platform that makes it so anyone can build VR apps directly in their browser.<p>We started this company part-time, building it during commutes to and from work on the train. Over the last 5 years, we've experienced many ups and downs:<p>- Gained early customers<p>- Quit our day jobs<p>- Secured angel funding<p>- Survived with a short runway<p>- Accepted into Techstars Chicago<p>- Survived with a short runway (again)<p>- Landed our biggest client ever, a Fortune 100 company<p>- Despite our highest revenue, our burn rate caught up to us<p>We looked at different ways to wind down the company and ultimately felt open sourcing the platform was the best way to do right by our customers.<p>Now, anyone who is interested in starting a VR company or just building an app can pick up where we left off. I'm excited about this space, if you need help with a VR app, or want to talk tech, please reach out.<p>Check out the repo: <a href="https://github.com/transferthought/transfer-thought">https://github.com/transferthought/transfer-thought</a><p>Contact me at keenan [at] transferthought [dot] com.
Show HN: Sonatino – small audio dev board based on ESP32-S3
Hi!<p>My name is Ben, and I recently updated my audio dev board "Sonatino" after receiving a lot of good feedback from the initial launch a year ago.<p>I began working on this after building a few projects that required audio capabilities. I was getting tired of wiring up external DACs and amplifiers to ESP32 boards, so I decided to look for a more compact, integrated solution. The available options either had larger footprints, non-standard connectors, or features that I didn't typically need for my projects. That's when I started working on a custom PCB that could be a sort of "audio swiss army knife". The result was Sonatino.<p>Some have criticized the use of a DAC and ADC that support HD sample rates and bit depths, especially when other factors will limit the usefulness of anything over 44.1kHz/16-bit audio. I actually agree - HD audio in this context is mostly overkill, but most modern audio chips support it and it's entirely optional. My primary goal was for the ADC and DAC to be easy to use - no I2C configuration required (like many of the CODECs available). It needed to be easy to use from an Arduino programming environment. The chips I selected (from Cirrus Logic) were a good fit; they just also happened to support higher sample rates / bit depths.<p>The latest revision drops the built-in antenna in favor of an external one. It also has a better speaker amp (3.2 W), an RGB LED, and improved power circuity. It's been a fun little board to work with!<p><a href="https://sonatino.com/" rel="nofollow">https://sonatino.com/</a><p>Check it out and let me know if you have feedback. Price is currently higher than I'd like, but that's a result of it being manufactured at low volumes.

Show HN: Improve LLM Performance by Maximizing Iterative Development
I have been working in AI space for a while now, first at FAANG with ML since 2021, then with LLM in start-ups since early 2023. I think LLM Application development is extremely iterative, more so than any other types of development. This is because to improve an LLM application performance (accuracy, hallucinations, latency, cost), you need to try various combinations of LLM models, prompt templates (e.g., few-shot, chain-of-thought), prompt context with different RAG architecture, different agent architecture, and more. There are thousands of possible combinations and you need a process that let’s you quickly test and evaluate these different combinations.<p>I have had the chance to talk with many companies working on AI products. The biggest mistake I see is a lack of standard process that allows them to rapidly iterate towards their performance goal. Using my learnings, I’m working on an Open Source Framework that structures your application development for rapid iteration so you can easily test different combination of your LLM application components and quickly iterate towards your accuracy goals.<p>You can checkout the project at <a href="https://github.com/palico-ai/palico-ai">https://github.com/palico-ai/palico-ai</a><p>You can locally setup a complete LLM Chat App with us with a single command. Stars are always appreciated!<p>Would love any feedback or your thoughts around LLM Development.
Show HN: I made a split keyboard for large palms
I had an issue a few years ago - every ergonomic keyboard I tried had the switches too close to each other and my fingers were cramped in that small space.
Then I decided to create a keyboard which is suitable for larger hands and eliminates most of the wrist movement. 34 keys was the most optimized version
for achieving as little wrist movement as possible.
You can try the fitment for your palm IRL with the printable template on the website.
