🍹 High Performance Node.js on the $5 Computer - Raspberry Pi

The Raspberry Pi is a very powerful computer in a tiny package. The cheapest option, the Raspberry Pi Zero, is capable of running a fully featured Linux distribution and driving a high definition display. It is the size of 3 coins (US Quarters) and costs $5. At $10, the Raspberry Pi Zero W comes with integrated WiFi and Bluetooth. Get a FREE Raspberry Pi kit ($25 value) With a generic ARM CPU and easy networking, the Raspberry Pi can easily become a personal application server for you.…

Rust ➡ WebAssembly 🚀 Node.js

💯 Performance advantages of Rust and WebAssembly

Senior software engineer Mohit Agrawal discussed his experience with Rust in an blog post. He compared runtime performance of Rust against other popular compiled and interpreted programming languages. Highlights from his findings: Rust is 2x (200%) faster, but uses only 1% of the memory compared with Java. Rust is 150x (15,000%) faster, and uses about the same amount of memory compared with Python. A study done by IBM found that Rust and WebAssembly could be 15x (1,500%) faster than compiled languages, such as Scala, which is traditionally considerred a high performance language.…

Access operating system resources from WebAssembly

The WebAssembly VM provides a sandbox to ensure application safety. However, this sandbox is also a very limited “computer” that has no concept of file system, network, or even a clock or timer. That is very limiting for the Rust programs running inside WebAssembly. If WASM+WASI existed in 2008, we wouldn't have needed to created Docker. That's how important it is. Webassembly on the server is the future of computing.…

The rustwasmc tool

Throughout our examples, we make extensive use of the rustwasmc tool. It is inspired by the wasm-pack project but is optimized for edge cloud and device applications. Specifically, it supports the WasmEdge WebAssembly runtime. Prerequisites The rustwasmc depends on the Rust cargo toolchain to compile Rust source code to WebAssembly. You must have Rust installed on your machine. $ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh $ source $HOME/.cargo/env $ rustup override set 1.…

🦕 Deno, Rust and WebAssembly

Deno is a JavaScript / Typescript runtime written in Rust. It is based on Google V8 engine (same as Node.js) and created by Ryan Dahl – the creator and original developer of Node.js. Q: Is Deno going to replace Node.js? A: It could. If it does, it will be one of the coming-to-age events for the Rust language for server-side applications. The same way Twitter made the Ruby language a legitimate choice for web apps almost 15 years ago.…

🔥 SSVM Performance

The Second State Virtual Machine (SSVM) is an open source WebAssembly runtime optimized for server-side applications. The SSVM provides not only a WebAssembly runtime in Node.js, but also a compiler toolchain ssvmup for Rust and JavaScript. Performance benchmarks These benchmark tests are entirely open source. Try them on your computer! The benchmark scores are in seconds. The smaller the better. The 👍 emoji marks the two best performing runtimes for each benchmark.…

⚙️ Machine Learning: K-means clustering and visualization

Machine learning uses statistics to find patterns in data, and then applies those patterns to act on new data. It is the driving force behind many Internet services. For example, machine learning could figure out the kind of food you like based on your personal history, and then recommend related restaurants to you. Machine learning is both computationally intensive and time sensitive, performance matters. The lingua franca of machine learning is Python.…

🦀 Rust Functions in Node.js

In the getting started with Rust functions in Node.js, we showed you how to compile high performance Rust functions into WebAssembly, and call them from Node.js applications. With JSON support, JavaScript code can call Rust functions with any number of input parameters and return any number of return values of any type. That allows us to take advantage of a large number of Rust libraries and crates in the ecosystem.…

Getting started with Rust functions in Node.js with VSCode

In this tutorial, I will show you how to experiment with Rust and Node.js development without installing any developer tools software. Why do I want to write Rust functions in Node.js apps? There are several compelling reasosns. Performance, security, portability, and manageability are among the key reasons. Fork this GitHub repository to get started. In your fork, you can use GitHub's web UI to edit source code files.…
