Today, we’re thrilled to announce Deno 2, which includes:

• Backwards compatibility with Node.js and npm, allowing you to run existing Node applications seamlessly
• Native support for package.json and node_modules
• Package management with new deno install, deno add, and deno remove commands
• A stabilized standard library
• Support for private npm registries
• Workspaces and monorepo support
• Long Term Support (LTS) releases
• JSR: a modern registry for sharing JavaScript libraries across runtimes

We are also continually improving many existing Deno features:

• deno fmt can now format HTML, CSS, and YAML
• deno lint now has Node specific rules and quick fixes
• deno test now supports running tests written using node:test
• deno task can now run package.json scripts
• deno doc’s HTML output has improved design and better search
• deno compile now supports code signing and icons on Windows
• deno serve can run HTTP servers across multiple cores, in parallel
• deno init can scaffold now scaffold libraries or servers
• deno jupyter now supports outputting images, graphs, and HTML
• deno bench supports critical sections for more precise measurements
• deno coverage can now output reports in HTML

Deno is a single binary for the TypeScript and JavaScript ecosystems. Deno is secure by default (installing npm libs do not automatically have full system perms/access).

The new standard library stabilizes a vetted collection of safe binaries instead of having to search for and install random libraries for basic or common use cases with [or without] own security assessments.

Deno compile compiles the TS/JS project into a single binary.

The backwards compatibility to npm and npm/js frameworks enables deno usage in existing projects and with existing libs with the benefits of deno and a path to incremental migration.

The announcement video is worth watching. The intro is great.

Every second Tuesday of October Ada Lovelace Day is celebrated - to commemorate the famous English mathematician of the XIX century, and the first programmer in history.

To mark this occasion, we rounded up a party of games that are not only fun to play, but can teach you to think like a true engineer and feel like a tech wizard!

Welcome to Ada Lovelace Day Sale. Hello, world!

researchers conducted experimental surveys with more than 1,000 adults in the U.S. to evaluate the relationship between AI disclosure and consumer behavior

The findings consistently showed products described as using artificial intelligence were less popular

“When AI is mentioned, it tends to lower emotional trust, which in turn decreases purchase intentions,”

Mapping C# array types to PostgreSQL array columns or other DBMS/DB JSON columns.

UI Components: Smart Paste, Smart TextArea, Smart ComboBox

Dependency: Azure Cloud

They show an interesting new kind of interactivity. (Not that I, personally, would ever use Azure Cloud for that though.)

There's a lot, and specifically a lot of machine learning talk and features in the 1.5 release of Opus - the free and open audio codec.

Audible and continuous (albeit jittery) talk on 90% packet loss is crazy.

Section WebRTC Integration → Samples has an example where you can test out the 90 % packet loss audio.
