Deno Deploy Beta 3 (via) I missed Deno Deploy when it first came out back in June: it’s a really interesting new hosting environment for scripts written in Deno, Node.js creator Ryan Dahl’s re-imagining of Node.js. Deno Deploy runs your code using v8 isolates running in 28 regions worldwide, with a clever BroadcastChannel mechanism (inspired by the browser API of the same name) that allows instances of the server-side code running in different regions to send each other messages. See the “via” link for my annotated version of a demo by Ondřej Žára that got me excited about what it can do. # 7th November 2021, 1:51 am

Subsume JSON a.k.a. JSON ⊂ ECMAScript (via) TIL that JSON isn’t a subset of ECMAScript after all! “In ES2018, ECMAScript string literals couldn’t contain unescaped U+2028 LINE SEPARATOR and U+2029 PARAGRAPH SEPARATOR characters, because they are considered to be line terminators even in that context.” # 15th August 2019, 10:30 am

Node.js is genuinely exciting
I gave a talk on Friday at Full Frontal, a new one day JavaScript conference in my home town of Brighton. I ended up throwing away my intended topic (JSONP, APIs and cross-domain security) three days before the event in favour of a technology which first crossed my radar less than two weeks ago.

node.js. “Evented I/O for V8 JavaScript”—a JavaScript environment built on top of the super-fast V8 engine which provides event-based IO functionality for building highly concurrent TCP and HTTP servers. The API design is superb—everything is achieved using JavaScript events and callbacks (even regular file IO) and the small standard library ships with comprehensive support for HTTP and DNS. Overall it’s very similar to Twisted and friends, but JavaScript’s anonymous function syntax feels more natural than the Python equivalent. It compiles cleanly on Snow Leopard. Definitely a project to watch. # 9th November 2009, 11:25 pm
And Now For Something Entire... Oooh! Shiny! Alex Russell on O3D, the new 3D browser plugin from Google that makes OpenGL accessible to JavaScript (and embeds V8 so performance won’t suck even on slower browsers). # 22nd April 2009, 12:19 pm
