I am looking to implement the RandomX Proof of Work hash function in JavaScript + WebAssembly. The README explains how this isn't possible: Web mining is infeasible due to the large memory requirement and the lack of directed rounding support…
I need to make a demo of a sweep line with multiple surfaces with reactjs, but The problem is that when I choose to show more than 1 surface it only plays on the data on the latest created surface…
I have a C++ project that uses EMSDK to compile to WebAssembly. I have an asset that my project loads, a bundle.zip that I currently use the '--embed-file' flag from the SDK at compile time, and this works. However, I…
(module (memory (export "memory") 1) (data (i32.const 0) "Hello World!") ) fetch('hello.wasm') .then(response => response.arrayBuffer()) .then(bytes => WebAssembly.instantiate(bytes)) .then(result => { // Access the memory const memory = result.instance.exports.memory; const buffer = new Uint8Array(memory.buffer); // Use the memory const offset…
I've decided to learn Rust alongside Web Assembly to get into more cloud computing. I'm trying to make a Rust app that connects to a Redis cache and increments a value each time a function is called. I then want…
I've been trying to reverse engineer a GBA emulator I found online (https://gba.44670.org/), and I used a HTML extracter to try to replicate it. I wanted it to work offline, so I downloaded all of the scripts to my computer,…
The code below reads the user-selected input file entirely. This requires a lot of memory for very large (> 10 GB) files. I need to read a file line by line. How can I read a file in Pyodide one…
I am trying to load sql-wasm.wasm from https://github.com/sql-js/sql.js such that it does not need a server. Otherwise, trying to load wasm from HTML gives CORS error. I converted it to base64 (~800KB) which looks like this const SQLBASE64 = "AGFzbQEAAAABrQRHYAJ/fwF/YAF/AX....AAJ4BAEHwogQLA4AWUQ==";…
I need to: Enable the user to select a plain text file from the user's filesystem. Make it available to Pyodide. Read its contents line-by-line in Pyodide (in the Python code). The code to read currently replaced by dummy code:…
How do I modify this line of Nginx config to allow my website to serve and execute in-line Web-Assembly (wasm)? add_header Content-Security-Policy "default-src 'self' http: https: ws: wss: data: blob: 'unsafe-inline'; frame-ancestors 'self';" always; Error Message: Content Security Policy: The…
