Show HN: BambooGrid – Open-source web UI for power grid modeling and power flow Hi HN, I am co-founder of Kickstage, a software company specializing in solutions for the electrical industry and lately grid operators. We are hiring engineers from different backgrounds, a lot of them software developers with limited experience in the sectors. Deep domain knowledge is key in our industry however, so we are constantly teaching the basics of power flow analysis, active vs reactive power, transmission line properties etc. With Jupyter notebooks and …
Show HN: Redis Rubix Bridge a HTTP API Redis Gateway https://ift.tt/PFngHBe
Show HN: Redis Rubix Bridge a HTTP API Redis Gateway Rubix Redis Bridge is an open source Redis HTTP API gateway compatible with Upstash Redis, Upstash Rate Limiter and Upstash Realtime. Before the usual comments, yes, native TCP is faster and exposing Redis directly to the internet is dangerous. The problem is that Redis has traditionally been difficult to use from serverless platforms and environments with dynamic IP addresses, strict firewall policies or networking restrictions where opening a Redis port is either impractical or impossible.…
Show HN: SirixDB 1.0 Beta – Git-Like Versioning, Diffs, Time-Travel Queries https://ift.tt/c28gHJ0
Show HN: SirixDB 1.0 Beta – Git-Like Versioning, Diffs, Time-Travel Queries Hi HN!

You can query any point in time, even individual nodes (for instance JSON values), diff arbitrary revisions, and efficiently track how data evolved without replaying events. Unlike traditional event stores, historica…

Show HN: A dashboard for tracking SK Hynix price gaps across exchanges https://ift.tt/1X6aZdD
Show HN: A dashboard for tracking SK Hynix price gaps across exchanges I built this after SKHY began trading to make it easier to compare the US ADR with SK Hynix’s Korean shares. The dashboard adjusts for FX and the ADR conversion ratio. It highlights the current pricing gap, how it changed over time, and comparable trading volume. Data comes from Yahoo Finance. Feedback is welcome! https://ift.tt/h5EI1q7 July 14, 2026 at 11:43PM
Show HN: ContextVault – Shared memory layer for your AI and your team https://ift.tt/qvjfMiy
Show HN: ContextVault – Shared memory layer for your AI and your team Hi HN, I'm Kevin. I built ContextVault because I kept running into the same problem with AI tools. Every project accumulated prompts, coding conventions, architectural decisions, examples, and other pieces of context that made the models significantly more useful. The problem was that this information quickly became fragmented. Some lived in ChatGPT Projects, some in Claude, some in Markdown files, some in internal documentation, and some only existed in previous convers…
