This is an evolving toolkit of capabilities helpful for analysing and reverse engineering legacy Cobol code. Currently, the following capabilities are available: - Program / Section-level flowchart generation based on AST (SVG or PNG) - Parse Tree generation (with export to JSON) - Control Flow Tree generation (with export to JSON) - Allows embedding code comments as comment nodes in the graph - The SMOJOL Interpreter (WIP) - Injecting AST and Control Flow into Neo4J - Injecting Cobol data layouts from Data Division into Neo4J (with dependencies like MOVE, COMPUTE, etc.) + export to…

We’re building an open-source language layer on top of Go, designed specifically for COBOL-style workloads: Native decimal arithmetic (COBOL-accurate) Record structures and copybook compatibility Batch jobs and transactional orchestration as first-class constructs Sequential / indexed file I/O baked into the runtime Compiles through Go for speed, concurrency, and cloud deployability Think of it as Kotlin for COBOL, or “COBOL on Go” familiar to mainframe engineers, powerful for modern developers. Test Results so far: NIST COBOL-85 validation: 77.61% overall (305/393 tests) NC…

I'm the lead developer of Otterkit. We've been working on this compiler for the past few months. The goal is to support the latest COBOL 2022 standard and compile it to C# (will support nativeAOT as well) Currently most of the work is being done on the parsing side of it to ensure that it can correctly parse all of the 2022 standard. We're almost done writing the parser, and will soon move to the codegen and runtime library. Please let me know what your opinion is on the project. I'll be here to answer any questions about it. We're also looking for contributors if anyone is interested in…

A common open source approach to observability will begin with databases and visualizations for telemetry - Grafana, Prometheus, Jaeger. But observability doesn’t begin and end here: these tools require configuration, dashboard customization, and may not actually pinpoint the data you need to mitigate system risks. Coroot was designed to solve the problem of manual, time-consuming observability analysis: it handles the full observability journey — from collecting telemetry to turning it into actionable insights. We also strongly believe that simple observability should be an innovation…

Hi everyone, we’re a small team, supported by Mozilla, who are working on re-imagining a UI for training, tuning and testing local LLMs. Everything is open source. If you’ve been training your own LLMs or have always wanted to, we’d love for you to play with the tool and give feedback on what the future development experience for LLM engineering could look like.

I'm working on a CLI that helps you create the boilerplate of your project in multiple languages and frameworks. In case of front-end frameworks/libraries, with cli you'll be able to create the project, set up git on your local, add the UI-framework, testing framework, and linting, and in the future releases you'll be able to even add pre-designed components. The CLI currently supports React, Angular, Vue, Svelte and Node.js will be released today. Also soon, you'll be able to deploy your applications to AWS with a single command. Appreciate your feedbacks and all the contributions are…

Hi HN! I’m Zach, co-founder / CTO of Platform Engineering Labs. We’re building formae, an open-source IaC system that stays in sync with real infrastructure instead of relying on manually maintained state and drift detection. We’ve just shipped Kubernetes, Helm, and Terraform .tfvars support. The goal with this release was simple: make it easy to start using formae with infrastructure people already have. formae can now discover existing k8s workloads automatically and the ability to utilize existing Helm charts. Coming from Terraform / OpenTofu and already have variable…
