Enable AJAX access for Tencent Serverless Cloud Functions

An important use case of serverless functions is to act as endpoints for AJAX calls from HTML web pages. This way, we can build truly “serverless” web applications with static HTML + JS pages on the front end, and serverless functions on the backend. A good example is this web page for fitting and plotting eigenvectors, a common machine learning task, on a 2-D data set. The web page calls a WebAssembly-based Tencent Serverless Cloud Function via AJAX.…

But can I use Ubuntu Server 20.04 on the smallest Raspberry Pi Zero? The NOOBS SD card you purchased from most online stores probably only has the 64-bit version of Ubuntu pre-installed. It would not boot on the 32-bit Raspberry Pi Zero (W).…

🦕 Tutorial: Deno Apps with WebAssembly, Rust, and WASI

Deno is created by the original developer of Node.js, Ryan Dahl, to address what he called 10 things I regret about Node.js. It did away with the NPM and the infamous node_modules. Deno is a single binary executable to run applications written in TypeScript and JavaScript. However, while TypeScript and JavaScript are suitable for the majority of web applications, they could be inadequate for computationally intensive tasks, such as neural network training and inference, machine learning, and cryptography.…

Is This the Next JAVA

In the post-Moore era, computer performance must come from more efficient software. Rust and WebAssembly provide Java-like memory safety, security, and portability to server-side applications while delivering high performance. Play with Rust functions in Node.js, and get recognized for your learning! Back in 2005, I had the honor of being voted as one of the very first Java Champions for evangelizing Java on the server-side. It is hard to believe now, but back then, most people are doubtful that Java could even be used in server-side applications.…
