The interesting things to me are:
- New JS runtime with 100% Node compat and passing 99% of Node's tests (the most compatible that I know of)
- Was essentially vibecoded in a few weeks by gpt-5.4 and a small team with minimal experience with Node internals and C++
From reading the blog post and briefly glancing at the code, the runtime works by running using WASIX (basically WASI but supports all Posix system calls).
What's cool is the actual JS engine (V8 right now, but conceptually could support any) is *not* compiled to Wasm but is instead exposed as a native host function so it's still fast and can JIT
The sandboxing comes from re-implementing every single Node module and swapping out all IO to use Edge.js's own implementation
These are actually NAPI functions exposed to JS, and there's a compilation step that compiles them to Wasm. When they're called it brings execution back into Wasm where system calls can be sandboxed by the Wasmer runtime
It looks like they made some changes to Wasmer runtime to directly support that by intercepting napi function registration calls and registering those functions in the runtime: github.com/wasmerio/wasme…
Wasmer@wasmerio
What if you could run ANY Node.js app unmodified, safely anywhere… without Docker, containers, or security headaches? 🔥 Introducing Edge.js • Fully compatible with Node.js • Sandboxed by design • Pluggable with any JS engine Node.js, but actually safe. And everywhere 👇

典型的なSSD故障の症状出たことあるが、もしかしたらレアなのかも。
まぁ、当時はストレージ無駄遣いしてた。やりたいことが多すぎたのもある
R-GRAY@Frozen_Frog_8
Mac商って10年超えてる人間だけどことApple Silicon世代でストレージ部分がぶっ壊れたとかストレージ側のせいで駄目だったとか聞いたことねえ。大概論理側が吹っ飛んだそんなんばっか。AHT通らないとか特にAppleSilicon世代は全然ない。てかそんなんならM1が6年経っても流通してない。

開発者兼Swiftの専門家のPaul Hudson氏が「SwiftUI Pro」というリポジトリを無料で公開した...!!!
Codex、Claudeでより良いSwiftのコードを誰でも専門家レベルで書けるようになる....!
改めてとんでもない時代。

Amazon just confirmed 16,000 layoffs but sources inside are telling me the real story is so much worse
Word from three different VPs: the 16K number is just "Phase One" - internal docs show another 14,000 cuts planned for Q2
A director in AWS walked me through their new "efficiency matrix" - entire teams being replaced by 2-3 senior engineers running Claude Sonnet workflows
The Alexa division got completely hollowed out. 847 engineers two months ago. 23 remaining after this week. All hardware development moved to a Bangalore team of 31 contractors with Cursor access
Here's the sick part: they're making the outgoing engineers document their entire decision-making process into "knowledge transfer sessions" that are being recorded and fed directly into training datasets
One L7 told me he spent his final two weeks creating detailed prompt libraries and workflow documentation. Thought he was being helpful for the transition
Turns out he was literally training the AI agent that replaced his entire org
The contractors offshore are using his exact prompts and shipping features 40% faster than his old team of 12 Americans ever did
Internal Slack shows leadership celebrating "operational excellence" while badges get deactivated in real-time
They're calling it "right-sizing for the AI era" in the all-hands
But the P&L sheets I'm seeing show $280M in salary savings this quarter alone
The knowledge extraction is complete
If you're still at Amazon and haven't started job hunting, you're already dead
