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…

Hey HN my name is Thassilo, I'm a student and passionate programmer from Germany. I want to showcase Spray, a small C debugger I've been working on for a few months now. Spray has a very simple and approachable interface. Its feature set is limited at this point, but it's already enough to tackle some basic problems. I stared to work on Spray because I was curious about how debuggers work. I am also trying to design Spray in such a way that it's easy to grasp and has a small mental overhead. I'd love to get your feedback on Spray. Email: d4kd (at) proton (dot) me PS: I'm generally interested…

Hi HN! We’re Adrien and Kanav. We met at our previous job, where we spent about a third of our lives combating a constant firehose of bugs. In the hope of reducing this pain for others in the future, we’re working on automating debugging. We’re currently working on a platform that ingests logs and then automatically reproduces, root causes and ultimately fixes production bugs as they happen. You can see some of our work on this here - https://news.ycombinator.com/item?id=39528087 As we were building the root-cause phase of our automated debugger, we realized that we developed…

Hey HN! I’ve been building OtterLang, a small experimental scripting language designed to feel like Python but compile down to native binaries through LLVM. The goal isn’t to reinvent Python or Rust, but to find a middle ground between them: Python-like readability and syntax Rust-level performance and type safety Fast builds and transparent Rust FFI (you can directly import Rust crates without writing bindings) OtterLang is still early and very experimental. the compiler, runtime, and FFI bridge are being rewritten frequently. Please star the repo, and contribute to help this project.

Usually, I’m a researcher working on areas like RL for coding agents – but one day I became annoyed by our slow VM startup times. So I took the plunge into systems engineering and built the first version of our VM hypervisor called otterlink. It now powers both our research & all of Devin production workloads. Compared to EC2, otterlink was able to bring down VM startup times by about 10x. The real pain point, however, were EC2’s long snapshot times. We want a lot of flexibility (e.g. forking, rollback and suspending VMs) that all require taking disk snapshots. On EC2 taking disk snapshots…

Sidekick is a live application debugger that lets you troubleshoot your applications while they keep on running. It allows you to add dynamic logs and put non-breaking breakpoints in your running application without the need of stopping & redeploying. Currently supporting Java, Python & Node.js runtimes. Sidekick Open Source is here to allow self-hosting and make live debugging more accessible. Built for everyone who needs extra information from their running applications.

Hey HN, I just built an experimental VSCode extension called LLM Debugger. It’s a proof-of-concept that lets a large language model take charge of debugging. Instead of only looking at the static code, the LLM also gets to see the live runtime state—actual variable values, function calls, branch decisions, and more. The idea is to give it enough context to help diagnose issues faster and even generate synthetic data from running programs. Here’s what it does: * Active Debugging: It integrates with Node.js debug sessions to gather runtime info (like variable states and stack traces). *…
