Show HN: Tiered storage and fast SQL for InfluxDB 1.x/2.x https://bit.ly/3Um7mQa

Show HN: Tiered storage and fast SQL for InfluxDB 1.x/2.x If you’ve run InfluxDB at scale, you know the pain: Retention policies mean throwing away history, keeping everything means huge hardware & license costs. We built ExyData Historian to fix that. What it does? - Automatically exports old InfluxDB 1.x/2.x data to compressed Parquet in S3 or MinIO - Keep recent data hot in InfluxDB, move the rest to cheap storage - Run fast SQL on archived data via Apache Arrow + DuckDB - Query it all through one interface and / API. No hot/cold boundary for the user Why it matters - 70–80% lower storage costs - Historical queries that are as fast (or faster) than InfluxDB itself - No manual exports, no query rewrites, no downtime Who’s using it right now? InfluxDB Enterprise Customers and Huge instances of OSS, telcos and logistics companies are trying this right now. We help you to reduce your Enterprise licensing cost, cause you are going to shrink your InfluxDB cluster. You keep your existing InfluxDB running, Historian works alongside it, moving history to cheap storage while giving you more analytics power. We’d love feedback from anyone managing large InfluxDB deployments. https://bit.ly/4mtrH1O August 8, 2025 at 11:18PM

Show HN: Trayce – "Burp Suite for developers" https://bit.ly/47kdorW

Show HN: Trayce – "Burp Suite for developers" About a year ago I introduced Trayce to HN as the "network tab for docker containers". Now I have released a new version which adds an HTTP client. The idea is to combine network monitoring with an HTTP client to help developers interact with and debug web application servers. Think "Burp Suite for developers". Trayce stores requests as local files using the .bru file format. The UI is based on Flutter which means it offers a super-fast and modern desktop GUI with a total download size of 13MB (on Linux). I am still adding features to it so would love feedback. Currently the new features in the pipeline are: OAuth2, GRPC, and scripting. It is open source and free to use but a perpetual license must be purchased for continued use. The license model is similar to that of Sublime Text. Thank you! https://bit.ly/3J5FixY August 7, 2025 at 03:49PM

Show HN: I built a simple tool to automate data into Google Sheets and BigQury https://bit.ly/47jzwmf

Show HN: I built a simple tool to automate data into Google Sheets and BigQury I’ve been a freelance data analyst/developer for a while and I’d regularly get hired to build custom data pipelines and dashboards in Google Sheets/Looker Studio. Custom data integrations came with a large upfront cost, and possible maintenance but clients told me they were reluctant to use the major data connector platforms as they were complicated and expensive over time, so I decide to fix this. I recently built SyncRange to be dead simple data connector to Google Sheets with a generous free plan and simple pricing. So far I’ve built out the following connectors based on the needs of my clients and early users: - Shopify - Facebook/Instagram ads - LinkedIn Ads - Google Ads - Google Analytics - Google Search Console I plan on adding more connectors as needed by my clients/users, most of which are in the ecommerce/marketing space so I will focus my time there. After years of building projects that I thought we interesting, but were not validated, I have really noticed the difference building something customers actually want. Please let me know if you have any feedback. https://bit.ly/4m0K0vq August 8, 2025 at 05:02AM

Show HN: From Hacking a T480 to the Fastest Open-Hardware 75 Hz E-Ink Display https://bit.ly/4fotyCI

Show HN: From Hacking a T480 to the Fastest Open-Hardware 75 Hz E-Ink Display Three years ago, I posted here about hacking together a fast e-ink laptop from a T480 because I was tired of spending all day on LCDs. I liked e-ink’s comfort, but it was too slow for day-to-day use. https://bit.ly/4mrPsr2 That post drew in people, which grew into a community experimenting with ways to make e-ink usable for everyday computing. That project later turned into a company and a multi-year project to make e-ink fast and open. We built our own FPGA-based controller, Caster, and went through multiple iterations to push past e-ink’s usual limits, slow refresh, ghosting, and proprietary controllers. Now, after three years, we’ve launched the Modos Paper Developer Kit and Monitor: the fastest open-hardware e-ink display, with 75 Hz refresh and sub-100 ms latency. It works with 6" to 13.3" mono or color panels over HDMI or USB-C, supports multiple grayscale modes, and has a C API for low-level control. The hardware, firmware, and schematics are on our GitHub. https://bit.ly/4munzP1 Our goal is to make e-ink fast and open enough that anyone can build on it, for hacking, research, or daily use. Thanks, HN, for being part of the journey. https://bit.ly/4frsqyh August 8, 2025 at 01:54AM

Show HN: I Built Economic Safety Mechanisms for AI https://bit.ly/459UQJO

Show HN: I Built Economic Safety Mechanisms for AI Title: I Built Economic Safety Mechanisms for AI - Seeking Feedback I have implemented the Reputation Circulation Standard (RCS), which uses exponential decay (like radioactive decay) to make harmful AI behavior economically irrational. The key insight: instead of trying to control AI, create environments where beneficial behavior is the only stable strategy. Power accumulation becomes mathematically impossible. Technical details: - Smart contracts for reputation circulation - Consensus algorithms for detecting divergence - <5% performance overhead - Scales with intelligence level Nassim Taleb endorsed the approach. Already implemented a simpler version for onchain recording of reputation for Animoca Brands - Moca chain. Now raising funds to deploy at AI labs before GPT-5: https://manifund.org/projects/preventing-ai-catastrophe-thro... Paper: [SSRN coming] https://deepthinker.xyz has paper. Demo available under NDA. Would love technical feedback from this community. https://manifund.org/projects/preventing-ai-catastrophe-through-economic-mechanisms---rcs- August 7, 2025 at 01:56AM

Show HN: Read the RFCs That Built the Internet Hi HN! I was using AI tools to research some of the RFCs people recommend you read and I thought why not build a tool that allows you to progressively do this and provides python examples, with dockerfiles to demonstrate some of the more complicated networking paradigms. It's not fully done yet, but I thought I'd show it off to get some feedback. https://bit.ly/453Jyqn https://bit.ly/4oqluFS August 5, 2025 at 03:49AM

Show HN: Using DSPy to enrich a dataset of the Nobel laureate network https://bit.ly/40OzoY5

Show HN: Using DSPy to enrich a dataset of the Nobel laureate network I've been working a fair bit with DSPy lately, and I did some work in combining the benefits of vector search and LLMs (via a DSPy pipeline) to disambiguate records with a high degree of accuracy to help enrich a dataset. The blog post shows how this approach scales well, is very cost-effective and super concise - all it takes is < 100 lines of DSPy code and it all runs async. The code to reproduce is in this repo if anyone's interested (all tools are 100% free and open source, and the methodology will work with open weight LLMs too). https://github.com/kuzudb/dspy-kuzu-demo https://blog.kuzudb.com/post/graph-data-enrichment-using-dspy/ August 5, 2025 at 02:09AM

Show HN: I built the fastest VIN decoder Decodes any VIN in ~20ms with zero network calls. I compressed the entire NHTSA vehicle database into a 21MB SQLite file that runs completely offline. No API keys, no rate limits, no servers. Just download once and decode forever. Works in browsers, Node.js, Cloudflare Workers - anywhere SQLite runs. Would love any feedback and to answer any questions about the implementation. https://bit.ly/3IYhnR3 August 5, 2025 at 12:42AM

Show HN: GPT helped me rebuild a .NET app in 30 mins what took 3 weeks in MFC https://bit.ly/46Gudx4

Show HN: GPT helped me rebuild a .NET app in 30 mins what took 3 weeks in MFC I've never used .NET, know nothing about .NET or vb, or anything outside vc++ & MFC. Recently I gave GPT a try, guiding it step by step, and asking it to help me rebuild a tool I originally wrote in MFC. To my surprise, it worked: a full Excel-to-PDF automation app, done in 30 minutes; including a small algorithm I thought would be too tricky for AI to handle. I didn't understand even a single line of the code, I just kept asking, copying, and running. It felt amazing… but also terrifying.If AI can do this now, what happens 5 years from now? Here's a 5-min video I made showing the full process with real code running (no cuts, just sped up): https://youtu.be/-mf_yOhOCfs Not selling anything. Just sharing what shocked me.

Show HN: Schematra – Sinatra-inspired minimal web framework for Chicken Scheme https://bit.ly/4le3cVk

Show HN: Schematra – Sinatra-inspired minimal web framework for Chicken Scheme I started this project a couple of weeks ago because I was stuck on my side project and needed some motivation. For a very long time I wanted to get back to do something useful in lisp/scheme, did a quick research and settled on CHICKEN mostly because it's relatively well maintained, fast enough, it's extremely easy to build/install and very easy to write interop to pretty much any library. Most of the projects that I've written on the side have been using some combination of Sinatra + Sequel + Postgres/Redis/Something else + HTMX. I love the simplicity of Sinatra's API so I decided to focus on trying to have a similar experience but in scheme, trying to make it ergonomic for a scheme dev (that part might not be there yet since I'm not an experienced scheme dev). The most fun part was the dev cycle: Emacs + NREPL + Aider (as a code reviewer & rubber ducky. For codegen it's mostly annoying but works great for documentation & refactoring). I hope to add full SSE & WebSocket support some time this week. Anyway, hopefully this is interesting to some of you and might be a source of fun :) https://bit.ly/4m1RfU1 August 1, 2025 at 09:56PM
