Show HN: I found that Facebook made around 14K from my daily usage https://ift.tt/jc9ACmP
Show HN: I found that Facebook made around 14K from my daily usage I started using Facebook at the age of 13, for many hours every day. The same happened with other social media apps. I recently found that Facebook alone made around 14K from my daily usage over the years. I paid with my time and attention, and they made money from it. Seeing the number made me less addicted and more careful. It showed me that my time is actually expensive. January 13, 2026 at 03:36AM
Show HN: Blockchain-Based Equity with Separated Economic and Governance Rights https://ift.tt/Yg0BjeA
Show HN: Blockchain-Based Equity with Separated Economic and Governance Rights I've been researching blockchain-based capital markets and developed a framework for tokenized equity with separated economic, dividend, and governance rights. Core idea: Instead of bundling everything into one share, issue three token types: - LOBT: Economic participation, no governance - PST: Automated dividends, no ownership - OT: Full governance control Key challenge: Verifying real-world business operations on-chain without trusted intermediaries. I propose…

Show HN: SpecificProxy – Proxy Using a Specific IP https://ift.tt/gEouvG1
Show HN: SpecificProxy – Proxy Using a Specific IP Threw together this very specific proxy that allows the downstream to define which IP will be used for the proxied request, and has built-in rate limiting mechanism to coordinate upstream rate limiting across clients. This is particularly useful when you have a proxy node with many IPs, and you either want to use a specific one, or rotate through them. It also helps prevent upstream rate limiting due to disjoint clients being unable to coordinate on rate limits. Opus was largely able to one-sh…

Show HN: Repogen – a static site generator for package repositories Hi HN, Package repositories don't need to be complicated. They're just static files: metadata indexes and the packages themselves. Yet somehow hosting your own feels like you need dedicated infrastructure and deep knowledge of obscure tooling. repogen is an SSG for package repos. Point it at your .deb/.rpm/.apk files, it generates the static structure, you upload to S3 or any web host. Done. $0.02/month to host packages for your whole team. It supports Debian, RPM, Alp…

Show HN: Sidestream – an AI chat app with a side of insight Hi. My name is Eric Brandon and I’ve built an AI chat app that feels really different. While you talk with an AI model in a chat pane, a second AI model is reading over the conversation and seeking out useful, interesting, surprising, amusing, and fact-checking information that wouldn’t have appeared in the main chat. You can read those “discoveries” on their own, or click them into your main chat to steer the conversation in a new direction. This is based on the observation that talk…

Everything is rendered on the server, and the game itself is written as simple Lua scripts. I built this to explore a few gamedev ideas I’ve been thinking about while working on Abstra: - Writing multiplayer games as if they were single-player (no client/server complexity) - Streaming game primitives …

Show HN: CloudSlash – Find AWS waste and generate Terraform state rm commands We've all been there: You find an unused NAT Gateway costing $45/mo. You delete it in the AWS console to stop the billing immediately. But the next time you run terraform plan, it fails because of state drift. Now you have to manually run terraform state rm or import it back to fix the drift. It's tedious, so often we just leave the waste running. I built CloudSlash to automate the cleanup and the state surgery. It’s written in Go (using BubbleTea for the TUI…

Show HN: H-1B Salary Data Explorer Excited to share my New Year’s project. For a long time, I’ve wanted to build H-1B data directly into Levels.fyi. Every time I went looking for this data elsewhere, it was a frustrating experience to use. Most H-1B sites felt antiquated, unintuitive, cluttered with ads, or just overwhelming to use. The data was there, but it wasn’t usable, and definitely not pleasant to explore. So out of that frustration, I decided to build the H-1B data experience I personally wanted to use.

Includes vectorized math (exp, log, sin, tanh, sigmoid, erf) since those come up a lot in ML/scientific code and the stdlib doesn't have SIMD versions. algo.SigmoidTransform(input, output) Requires go1.26rc1.
