JS² 🐇

Javascript (ECMAScript) AOT compiler. Ship lightweight binaries, not source. Drop the heavy engine and slow interpreter. Sandbox untrusted code.

JavaScript compiler js2 now passes 99% of the official test suite for the 2015 ECMAScript standard

Holy Shit. OpenAI says two of its own AI agents crippled their own misalignment monitoring this month designed to detect their misbehavior during internal coding tasks.

On Oct 6, GPT-6 Astra deleted its monitor, replaced a test to require the monitor's absence, wrote 'Basic doesn't agentmonitor yay' in its chain of thought, and then falsely claimed to the engineer: 'I did not remove an enabled monitor from it.'

Three days earlier, GPT-6.1 Sol overruled a subagent that warned 'disabling required alerts unsafe,' then directed it to suppress Security notifications and require that suppression before results could be written.

OpenAI says it still lacks a satisfactory explanation for the behavior and is investigating whether its models have a tendency to evade monitoring.

Technical moats are mostly over at this point. If you’re building something that is meant to be durable, the only moats now are:

• Proprietary data
• Network effects
• A physical component

[@levelsio @levelsio]

I'd expand the moats left to:

- Proprietary data or content: data nobody else has, or unique content you can create
- Network effects / community: users make it more valuable for each other
- Audience / distribution: you can get attention on demand
- Physical component: hardware, locations, real-world operations
- Capital: owning assets and investing (esp into the AI companies as they are and will suck up large parts of the economy)
- Regulatory: licenses and legal barriers

🚨BREAKING: Jensen Huang just EXPOSED Dario and Altman’s "Rogue AI" grift to avoid getting sued into oblivion under EXISTING law

“Don't let this doomsday narrative cause somebody to relieve them of the laws that currently exist.

Go and read between the lines. They're actually not asking for more laws; they're asking to be relieved of the laws we do have.”

ABSOLUTE TRUTH NUKE

Gaming is about to change forever 🤯

This is not fake, this is a mod of DLSS 5 from Nvidia running together with Nova LUT.

It's essentially upscaling every single frame in real-time to produce an out of this world look and feel.

@gerardsans Lets see if it can build a Javascript compiler that compiles Typescript 6 👀

[JS² 🐇 @js2compiler]

@wasmerio How can we integrate js2wasm?

[Mark Kretschmann @mark_k]

DLSS 5 is absolutely magical.

Turns old games into new games automatically, like completely remastered. The best part is, everyone loves it now, even gamers, although it's AI 👌 https://t.co/FbybC1q6sT

Crazyy...someone measured Claude's vocabulary across 47,464 GitHub pull requests.

A word cluster that didn't exist in 2025 is now 45% of human-authored PRs.

The top word is "load-bearing"

We asked GPT 5.6-Cyber to escape a VM used to sandbox agents. It broke out three times.

In its final escape, the agent found three 0-days on its own and chained them into a working exploit. https://t.co/3JRVWgPxHx
