Show HN: Reladraw – A diagram language where you decide where to place things

I love making diagrams to help understand, plan, etc. However, the options are (A) auto-placement languages like Mermaid or Graphviz (which don't let me decide how the diagram looks), or (B) software like Draw.io which are powerful but are very time consuming (and inefficient for agents to manipulate). I wanted to have the benefits of both, where you can define a diagram in a diagram language,…

<Hacker News Best> has shared a new project called Reladraw, a diagram language that allows users to decide where to place elements within their diagrams. This innovative tool aims to bridge the gap between auto-placement languages like Mermaid or Graphviz, which lack control over diagram appearance, and complex software like Draw.io, which can be time-consuming and inefficient for agents to manipulate.

The project offers a playground on GitHub for users to try Reladraw without installation, along with instructions for simple npm installation and installing a skill compatible with Claude or other agents. The project has garnered 172 points and 52 comments on Hacker News.

What a hard, high-impact cloud change looks like from the inside

Let me show you what a hard high-impact change actually looks like in practice A team I worked with had a microservices architecture. Seven services. All of them deployed in one region.

  • Microservices architecture deployed in single region with data transfer bill of $3,200/month
  • Three services in different availability zones causing $3,200/month data transfer costs
  • Coordination, testing, and cutover effort reduced data transfer bill to $400/month

The quadrant that swallows engineering teams whole

Hard low-impact work is the most dangerous quadrant on the list Not because the work is harmful. Because it feels like real progress while delivering almost none I know this one personally Early in my…

Ransomware Detection for Windows and Linux using ETW and eBPF

I build ET Ducky, an RMM that reads the kernel event stream on each endpoint. We launch on Product Hunt on Tuesday, September 29, and today I'm writing about the behavioral rule engine. Every managed agent runs thirteen built-in rules against its own kernel event stream.

  • ET Ducky launches on Product Hunt, offering ransomware detection for Windows and Linux.
  • Engine runs on same thread, preventing rule blocking.
  • Rule set includes mass-file-rename and file-encryption-sweep patterns.
