I'm working on a new app for creating technical diagrams - https://vexlio.com . It's an area with some heavyweight incumbents (e.g. Visio, Lucid) but I think there's good opportunity here to differentiate in simplicity and overall experience. I'm still in the fairly early phase, and I suspect I haven't quite found the best match of features to customers yet. From a dev perspective this area has a ton of super interes…

Super cool. Do you consider yourself to be a competitor with Mermaid?

https://spring-agriculture.com/ Autonomous robotics for sustainable agriculture. Based in the south of the UK. Prototypes of an autonomous mechanical farm-scale weeding robot currently beginning real-world testing. Still a huge amount of work to do though. Hardware and software developed fairly much from scratch, not using ROS (for not entirely crazy reasons...); everything written in Rust which I find well suited to…

Very interesting

I have seen a few of these, but only one (about a decade ago) that used legs not wheels

Wouldn't it be better if the robot walked rather than rolled?

You may be able to illuminate this for me...

I‘m building Sticker, a simple note-taking app for Mac that lets you add markdown based notes to applications, files and other windows. The note is only shown when the connected file, window or app is selected / has focus. Currently, I use it myself to add notes to specific files and projects, e.g. adding a note to my tax folder for 2025 instead of creating a txt file or adding a ToDo to a specific workspace when opened in VS Code. The notes are completely file/markdown based and can be simply synced with other devices. This way, it’s also possible to edit the note outside of Sticker.

I'm building the Enact Protocol: https://enactprotocol.com

Turn any command into an AI-discoverable MCP tool with a few lines of YAML:

   name: hello-world
   description: "Greets the world"  
   command: "echo 'Hello, World"
Any AI agent can search for "greeting" and use your tool. I'm also building the first registry at https://enact.tools

Working on RSOLV.ai - automated security vulnerability remediation. Currently a one-man shop.

The insight: Most security scanners find problems but don't fix them. Industry average time to fix critical vulnerabilities is 65+ days. We generate the actual fixes and create PRs automatically, including educational content on the nature of the vulnerability and the fix in the PR description.

Technical approach: - AST-based pattern matching (moved from regex, dropped false positives from 40% to Business model experiment: Success-based pricing - only charge when fixes get merged ($15/PR at the moment). No upfront costs. This forces us to generate production-quality fixes & hopefully reduces friction for onboarding.

Early observation: Slopsquatting (AI hallucinating package names that hackers pre-register) is becoming a real attack vector. It's pretty straightforward to nail and has a lot of telltales. Building detection & mitigation for that now.

Stack: Elixir/Phoenix, TypeScript, AST parsers
