[Testing] Performance Debugging with LLVM-mca: Simulating the CPU

Show HN: Octelium – FOSS Alternative to Teleport, Cloudflare, Tailscale, Ngrok I have been working on Octelium for quite a few years now but it was open sourced only by late May 2025. Octelium, as described more in detail in the repo&#x27;s README, is simply an open source, self-hosted, unified platform for zero trust resource access that is primarily meant to be a modern alternative to corporate VPNs and remote access tools. It can operate as a remote access&#x2F;corporate VPN (i.e. alternative to Twingate, Tailscale, OpenVPN Access Server, etc...), a ZTNA&#x2F;BeyondCorp platform (i.e. alterntive to Cloudflare Access, Teleport, Google BeyondCorp, etc...), and it can also operate as an API&#x2F;AI gateway, an infrastructure for MCP and A2A architectures and meshes, an ngrok alternative, a homelab infrastructure or even as a more advanced Kubernetes ingress. It&#x27;s basically designed to operate like a unified Kubernetes-like scalable architecture for zero trust secure&#x2F;remote access that&#x27;s suitable for different human-to-workload and workload-to-workload environments. You can read more in detail the full set of main features and links about how it works in the repo&#x27;s README or directly in the docs <a href="https:&#x2F;&#x2F;octelium.com&#x2F;docs" rel="nofollow">https:&#x2F;&#x2F;octelium.com&#x2F;docs</a>

[Code Quality] Show HN: Query your Rust codebase and generate types for anything Hello HN!<p>As a long-time professional Rust developer. I&#x27;ve always been frustrated by the difficulty and &quot;hackiness&quot; of producing bindings to other languages, whether a frontend, an FFI library, etc.<p>Not just in Rust but in any language.<p>After many years of trying existing solutions and trying to make my own, I&#x27;ve finally developed a solution I&#x27;m very happy with.<p>RTK (aka Rust Type Kit) allows you to write Lua scripts that perform queries on your code, such as method calls to Axum&#x27;s `.route`, function definitions, and more, and then receive rich type information including all argument types, function paths, proc macro attributes, and more.<p>Your Lua script can then read this information and emit an output file in any language of your choosing. Or, you can emit compiler errors and use it as a linter of sorts. You can even directly re-emit Rust code itself and use this as a richer proc macro solution!<p>The code example is a bit verbose, so I encourage you to take a look at the repo&#x27;s README. I look forward to hearing your thoughts, or any usecases you may come up with!

Show HN: I'm an airline pilot – I built interactive graphs/globes of my flights Hey HN!<p>Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history.<p>This globe is probably my favourite so far: <a href="https:&#x2F;&#x2F;jameshard.ing&#x2F;pilot&#x2F;globes&#x2F;all" rel="nofollow">https:&#x2F;&#x2F;jameshard.ing&#x2F;pilot&#x2F;globes&#x2F;all</a><p>If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!
