Show HN: Dead man's switch without reliance on your infra
I wrote this Go project to implement a dead man’s switch that didn’t rely on cron jobs, timers, databases, etc on the infra it runs on. Deadcheck integrates to PagerDuty and keeps a long running incident snoozed until expected check-in times where it’ll alert unless a check-in occurs.

Show HN: NotesHub: cross-platform, Markdown-based note-taking app
Thank you for your comments, just some context:<p>- The app is available for iOS, Android, Windows, Mac, Apple Vision Pro, and the Web.<p>- The Web version is implemented as a Progressive Web Application that is very responsive, local first, offline first, can be installed, and is entirely free to use.<p>- Native (hybrid) versions do not require subscription fees and have small one-time payment.<p>- You can store your notes in Git using any Git provider such as GitHub, GitLab, or Bitbucket. However, it has the best built-in integration with GitHub. Self-hosted scenarios like Gitea are also supported. In addition to Git, you can store your notes in a file system and iCloud Drive on Apple Devices.<p>- It has a rich Markdown syntax support with added extensions like Mermaid, ABC music notation, callouts, etc.<p>In addition to regular Markdown notes, you can create Kanban boards for easy task management (under the hood, it is still stored in Markdown). If that is not enough, you can create whiteboards based on Excalidraw and embed them back into your notes.

Show HN: My microkernel-based OS built from scratch now has basic Unix commands
This project contains no code from Linux, BSD, Minix, or any other OS. Everything up until this point is written entirely from scratch, including a pure microkernel (that only implements multiprocessor priority scheduling, memory management, and interprocess communication), a work-in-progress implementation of the standard C library, and a variety of servers that provide drivers and other essential OS functionality.<p>At the time of writing this post, the servers provide drivers for the keyboard, NVMe SSDs (that works on real hardware), a Unix-like virtual file system (with a single root mountpoint, /dev, /proc, etc.) and several other necessities. The main goal of this project is to research OS design and try to overcome some of the performance penalties associated with microkernels, while also building a general-purpose usable Unix-like OS on top of it. It's also intended to make the study of OS development and theory a little more approachable through self-documenting, clean, and readable modular code.
Show HN: Squey, an open-source GPU-accelerated data visualization software
While we hope you'll find it quite useful already, there is plenty of room for improvement so we greatly appreciate your feedback!
Show HN: Tenno – Markdown and JavaScript = a hybrid of Word and Excel
Tenno is a web app that lets you create Markdown documents that can include computational cells.
You can think of it as a mix of Word and Excel, some sort of "literate programming" environment.<p>This is still an early version but I wanted to get some feedback from HN on what could be nice features to add.<p>Check out the Docs and examples page, it has a ton
of (in my humble opinion) cool stuff!<p>Why did I build this?
I was building some estimation for cloud costs in Google Sheets and I quickly ended up with a mess. I realized that if I wanted to analyze how a certain thing changes wrt to multiple variables by plotting it, I had to create a bunch of copies of data and copy my formulas everywhere... a SWE nightmare!<p>Tenno simplifies this because you can essentially define a function you are interested in, and only the analyzing it using plots that explore various dimensions.<p>BTW, you can also use Tenno to build dashboards by pulling data from APIs, checkout the weather data example.
