Show HN: Start GPT threads in ChatGPT (& other sites) https://bit.ly/41Cm9KO

Show HN: Start GPT threads in ChatGPT (& other sites) I noticed current LLM chat apps don't support threads for follow questions, but instead they're one long conversation. Often when I'm digging into a topic and GPT responds with a book, I want to ask follow-ups in "side chats" that I'd prefer to be inline and in context rather than jumping to bottom of the page, so I created GPT threads. It's a chrome extension where you can highlight some text and start a chat focusing on that text and incorporating surrounding context. You can have multiple threads on a page, and the extension has configurability like surrounding context size, response lengths, chat box positioning. I've found it useful for other sites too to quickly ask questions about news articles, docs, or HN threads!

Show HN: a Rust library for creating hierarchical state machines https://bit.ly/3Xn5oRm

Show HN: a Rust library for creating hierarchical state machines I've come to prefer modeling state machines with nested states, but implementing them by hand requires a large amount of error-prone boilerplate that obscures the important logic of the state machine. I found that the existing offerings in the Rust ecosystem - while inspiring - lacked a number of features that I was looking for, so I spent the last few months building moku. Feedback is welcome! https://bit.ly/41jRmkM March 1, 2025 at 12:30AM

Show HN: Hexle: A powerful way to search for papers and connect your ideas https://bit.ly/4ijEDFy

Show HN: Hexle: A powerful way to search for papers and connect your ideas Hi all, I find literature searches to be slow and despite all the tools nowadays, it is difficult to map out vast areas of research and then connect my ideas to what I’m trying to do (e.g. writing a review, learning something new, planning a new project, assignments, etc). Some of my peers and teachers also found this to be a problem so I built this MVP app to help people not only leverage AI search capabilities but also go on to connect their ideas, map out research projects, cite various results and organise their “stream of consciousness” as they work. I’d love to get some feedback on it - please feel free to post it either in this thread or email me at hexleteam@gmail.com. Many thanks from Sydney, Australia :) https://bit.ly/4iivOvx February 27, 2025 at 11:46PM

Show HN: SuperMassive – Fast durable, in-memory, distributed key-value database https://bit.ly/4kiiyZx

Show HN: SuperMassive – Fast durable, in-memory, distributed key-value database Hey hn! I hope you're all doing well. I’d like to share a new open-source database I’ve designed and written called SuperMassive. SuperMassive is a scalable, distributed, in-memory key-value database designed from the ground up to allow for high concurrency, fast writes, fault tolerance, and durability while remaining simple to use and efficiently scalable. The idea for SuperMassive comes from its name.. I wanted to build a key-value database that can scale infinitely, remain durable, be self-healing, consistent, and blazing fast. I also wanted to simplify sharding and replication compared to existing distributed KV stores and their protocols. SuperMassive is built to be simple yet powerful. It consists of just one multiplatform supported binary that can run in multiple modes(cluster, primary node, or replica). Nodes function as shards of your data. The design emphasizes minimal configuration, high performance, and automatic failover. While SuperMassive is still in its early stages (v1.0.2b), I’d love to hear your thoughts on the design, its architecture, and any feedback you may have :D Features~~ ~ Highly scalable Scale horizontally with ease. Simply add more nodes to the cluster. ~ Distributed Data is distributed across multiple nodes in a sharded fashion. ~ Robust Health Checking System Health checks are performed on all nodes, if any node is marked unhealthy we will try to recover it. ~ Smart Data Distribution uses a sequence-based round-robin approach for distributing writes across primary nodes. This ensures that all primary nodes get an equal share of writes. ~ Automatic Fail-over Automatic fail-over of primary nodes on write failure. If a primary node is unavailable for a write, we go to the next available primary node. ~ Parallel Read Operations Read operations are performed in parallel. ~ Consistency Management Timestamp-based version control to handle conflicts. The most recent value is always returned, the rest are deleted. ~ Fault-tolerant Replication and fail-over are supported. If a node goes down, the cluster will continue to function. ~ Self-healing Automatic data recovery. A node can recover from a journal. A node replica can recover from a primary node via a check point like algorithm. ~ Cluster Authentication with basic like auth. ~ Simple Protocol Simple protocol PUT, GET, DEL, INCR, DECR, REGX, STAT, RCNF, PING. ~ Async Node Journal Operations are written to a journal asynchronously. This allows for fast writes and recovery. ~ Multi-platform Linux, Windows, MacOS https://bit.ly/41CnAJq https://bit.ly/41z0enW - Alex https://bit.ly/41z0enW February 27, 2025 at 09:31AM

Show HN: Libredesk – Open-source customer support desk. Single binary app https://bit.ly/4gVaDyJ

Show HN: Libredesk – Open-source customer support desk. Single binary app Libredesk is a 100% free and open-source customer support desk, the backend is written in Go and the frontend is in Vue JS with ShadnCN for UI components. Unlike many "open-core" alternatives that lock essential features behind enterprise plans, Libredesk is fully open-source and plans to always stay this way. It's in alpha (v0.1.0) right now, but there’s a working demo available. I built this because I wanted a truly open and self-hosted alternative to platforms like Chatwoot, Intercom, and Zendesk. Would love feedback, suggestions, and thoughts from the community. GitHub: https://bit.ly/43damDQ Demo: https://bit.ly/3XkKthX https://bit.ly/43damDQ February 24, 2025 at 12:05PM

Show HN: Telescope – an open-source web-based log viewer for logs in ClickHouse Hey everyone! I’m working on Telescope - an open-source web-based log viewer designed to make working with logs stored in ClickHouse easier and more intuitive. I wasn’t happy with existing log viewers - most of them force a specific log format, are tied to ingestion pipelines, or are just a small part of a larger platform. Others didn’t display logs the way I wanted. So I decided to build my own lightweight, flexible log viewer - one that actually fits my needs.

Show HN: I created a language called AntiLang – breaking all the conventions https://bit.ly/4hRjkLK

Show HN: I created a language called AntiLang – breaking all the conventions AntiLang is an interpreted programming language written in Go. The basic idea of this is to keep all the logical parts of a language same, but reverse the structure of it. The idea for this project came when I was having a long midnight conversation with my friend and thought of writing such a weird language. The initial draft was far worse than the current implementation; we thought of reversing the brackets and the language would be read from bottom to top. I'm happy that I dropped that idea Technical details: As the interpreter is written in Golang, I compiled it to WASM, and the whole interpreter is running in the browser. For the editor, I'm using Monaco, the same library that powers the text editor in VSCode. I learnt how to build it while reading "Write an Interpreter in Go" by Thorsten Ball. The project is opensourced - https://bit.ly/41xK6Dc - do give it a star if you like the project. https://bit.ly/3D9kwLm February 23, 2025 at 08:00PM

Show HN: URnetwork – Decentralized VPN Replacement https://bit.ly/3QwwIbQ

Show HN: URnetwork – Decentralized VPN Replacement I spent the last 1.5 years working out how to scale a decentralized network safely and efficiently to millions of users. URnetwork is a market for network capacity, where each connection races to find the best provider on the network. This means users have many IP addresses that continually cycle, and users can directly connect to each other, which is great for privacy when some minimum conditions are met. Because the world already has a bunch of hardware and network capacity that can be used, the challenges were to design a protocol to make it safe to use and participate, fast and reliable, and to set up the right encryption bar for safe peer to peer data. You can try the apps on iOS and Android and see if they work better than your current VPN. The source is here https://bit.ly/3QvX3qP About me, I was an early engineer at Palantir, former YC founder, and spent the last decade building global infrastructure. I'm interested in truly free, transparent, private, available, and secure networks that reward people to contribute what they have. Ease of use and safety to participate has been a big focus for me. https://bit.ly/3QTppLT February 24, 2025 at 10:17PM
