Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

SMB Unreal Scanner

smb-unreal-scan is a single executable with two command-line modes:

  • Standalone scanner mode, used when no drop-in server port is provided.
  • Reality Hub SMB drop-in mode, used when -port=<port>, --port <port>, or --dropin-server is provided.

Standalone Scanner

smb-unreal-scan --root //server/share/path --env .smbenv --output scans

The standalone scanner keeps the original high-concurrency traversal behavior.

Reality Hub TCP Drop-In Mode

Reality Hub launches the old Go SMB binary with -port=<port>. The same flag now switches this binary into protobuf-over-TCP mode:

smb-unreal-scan -port=15000

Equivalent explicit form:

smb-unreal-scan --dropin-server --mode=tcp --port 15000 --pool 96

Drop-in mode preserves the existing protobuf message types and wraps requests in length-prefixed RpcFrame messages over 127.0.0.1 TCP. Runtime caches stay in memory only for the current backend process/mount. No cache is persisted or reused across test runs.

Local Verification

On macOS arm64 against //172.16.0.20/PublicStorage/HUB/projects:

  • Standalone scanner mode completed in 8.1s.
  • Release drop-in mode completed the Reality Hub stub scan in 5.519s.
  • Strict comparison against the Go reference passed with 0 diffs for 41 projects and 617 maps.

NPM Package

The assumed Reality Hub package name is @zerodensity/smb-cpp. The package is staged from release bundles with:

npm run build

The staging output is dist/npm and contains:

  • darwin_arm64/smb_server_cpp_darwin_arm64
  • linux_x64/smb_server_cpp_linux_x64
  • win32_x64/smb_server_cpp_win32_x64.exe
  • smb2.proto

Platform folders may also contain runtime sidecars, such as the libsmb2 runtime, and Reality Hub copies the whole selected C++ platform folder next to the executable.
