Show HN: Envoy playground in the browser
Hey HN,<p>We made an Envoy Proxy playground [0] so we could test out our Envoy configs directly in the browser. This is based on Julia's work with Nginx Playround. [1] We forked that repo and added more Envoy to it. [2] Check it out!<p>[0] - Envoy is a popular programmable proxy similar to Nginx or HAProxy that is popular with cloud-native setups: <a href="https://www.envoyproxy.io" rel="nofollow noreferrer">https://www.envoyproxy.io</a><p>[1] - <a href="https://nginx-playground.wizardzines.com" rel="nofollow noreferrer">https://nginx-playground.wizardzines.com</a><p>[2] - <a href="https://github.com/apoxy-dev/envoy-playground">https://github.com/apoxy-dev/envoy-playground</a>
Show HN: I made a little tool to practice country positions on the world map
Hi HN,<p>I built a little tool to help me get better at remembering country locations on the map: <a href="https://learn-worldmap.netlify.app/" rel="nofollow noreferrer">https://learn-worldmap.netlify.app/</a><p>It's made from plain HTML/CSS/JS, and not intended to make any money or anything. Just thought that maybe someone else may enjoy it. Also of course happy about any feedback!<p>Cheerz.

Show HN: Chie – a cross-platform, native, and extensible desktop client for LLMs
I'm submitting this before going to bed, so by the time it hits front page (if it does at all) I'll likely be asleep, so I won't be able to answer questions in time.

Show HN: Pebble Finance – Personalize Your Investments Today
Hello HN,<p>We are Pebble Finance! Our newly launched product offers a custom indexing solution, empowering investors to personalize their investment portfolios.<p># The product<p><i>What our product is now:</i>
We are creating a platform for users to use natural language to search for their interests and personalize their portfolio.<p>Search is a combination of using OpenAI LLM models with Langchain, OpenSearch index, and some traditional NLP techniques. Search is divided into several tools which are selected based on the user’s input query. Based on the complexity of the input query, a single tool or a combination of tools can be used to return a list of companies for the user’s portfolio. Also based on the complexity of query search times can vary from less than a second to up to 15 seconds.<p><i>List of tools</i><p>- Themes - General themes or concepts such as type of company<p>- Index/ETFs - Search for common ETFs such as S&P 500, Russell1000, and Russell3000
Location - Currently we can search for US states and countries (we are going to be adding in US cities soon as well)<p>- Fundamental Metrics - Filter companies based on fundamental metrics such as market cap, revenue, and pe ratio<p>- Supplier Data - Identify companies based on their supplier relationships<p><i>What we would like to add:</i><p>We are looking to add more tools to add more functionality for users. Some tools we are looking to add are based around news integration, historic stock price, and expanding our sources of data<p>We are also trying to improve search speed while keeping quality of results consistent so we are looking at new ways to parse queries such as with fine tuning transformer models and looking at more traditional NLP techniques.<p><i>Challenges we have come across</i><p>We are seeing issues with trading off between speed and quality of search results. Many of the queries can take up to 15 seconds based on the complexity. Also saw issues where LLMs are producing hallucinations which led to incorrect results. We have mitigated this issue by using OpenAI’s davinci-003 model versus gpt3.5-turbo, but this also increases overall cost.<p><i>Some Example Queries</i><p>- I want to invest in eco friendly companies<p>- Faang without the n<p>- Electric cars without elon musk<p>- Californian companies<p>- Aapl<p>- Top marketcap companies<p>- ev companies with marketcap above 10 billion<p>- s&p without apple<p># Feedback<p>Please try out our search capabilities on pebble.finance/themes and check the results!<p>We would really love honest feedback on search results, suggestions on improving results/speed, future tools, and/or general thoughts!<p>Thanks for reading!<p>The Pebble Finance Team

Show HN: Subset – Spreadsheet building blocks on an infinite canvas
Hey HN! We’re excited to show you Subset (<a href="https://subset.so" rel="nofollow noreferrer">https://subset.so</a>)! Subset is a spreadsheet on an infinite canvas where you can drop in spreadsheet building blocks and connect them together to easily build good looking analytical tools.<p>My cofounder and I both worked in finance before this. We quit our jobs and learned to code to build the spreadsheet we always wanted.<p>We got frustrated with how much time was wasted recreating the same thing from scratch or trying to extract something reusable from a previous spreadsheet. We wanted a spreadsheet with more composability and a community of building blocks to work off of.<p>Why infinite canvas? Reusability is not really a first class concept in a traditional endless spreadsheet grid [1]. A canvas felt more intuitive. You can communicate data flow, better understand inputs/outputs, and quickly make data presentable.<p>Subset is browser based and real-time multiplayer. It is free to use. We haven’t figured out a pricing model yet, but we imagine it’ll be a freemium SaaS model.<p>We’ve spent a lot of time on getting the core spreadsheet functionality as close to Sheets/Excel as possible, but there’s a lot more to do here. This list could be endless, but let us know if we need anything in particular.<p>Here’s a couple templates to explore:<p>Splitting a bill that includes sharing items - <a href="https://subset.so/templates/how-to-split-a-bill" rel="nofollow noreferrer">https://subset.so/templates/how-to-split-a-bill</a>
