Is learning to code illegal today?

Cloudflare and VoidZero are porting the TypeScript compiler to Rust. It's called tsrs, built with the TypeScript team, and it's not a fork.

Cloudflare's early numbers: up to 8x faster than TypeScript 7.0 with ~70% less memory at the same worker count.

Try it with npx tsrs.

A team lead on Reddit applied to his own job with his own CV under a fake name. Auto-rejected in 6 minutes.

The filter wanted "React.js". His CV said "React".

Every qualified applicant since April, gone over one dot. Most expensive punctuation of the year.

DeepSeek open-sourced DeepInfer, the inference framework behind its own production serving. Apache 2.0.

It runs one model, V4.1-Flash, on NVIDIA SM100 GPUs or Huawei Ascend 950 NPUs.

No KV cache system or prefill/decode split yet, so a full service still needs your own glue.

Google's LiteRT Tensor API: build models op by op in C++, no model file.

One graph runs on CPU, GPU or NPU. Weights load from .safetensors.

Google's test: SAM 2 ~1.5x faster than Apple MLX on a MacBook Pro.

Google says convert with LiteRT Torch first. This is for deep tuning.

That instant gut no in a meeting is years of shipped bugs talking, and it's the one part of the job an agent can't autocomplete for you.

We desperately need your latent knowledge and experience.

That's the stuff sitting in the back of your mind that surfaces when someone makes a suggestion in a meeting and you instantly know it's a bad idea but it takes you a second to articulate.

You're still needed!

Let's Encrypt adds two remote validation perspectives, announced Oct 15.

Each domain check: 7 requests, 1 primary plus 6 remote, up from 4. Baseline Requirements want 5+ remote from Dec 15.

Staging Oct 27, prod Nov 10.

Geoblock your challenge endpoint and renewals can fail.

@kentcdodds After years of pushing mobile apps through store review, watching AI plugin marketplaces reject updates with vague reasons feels like the App Store in 2012 all over again.

@theo I've been coding since 2012 and agents write most of my code now, but the night it all collapses is still the night you need someone who knows why it broke.

Xcode 27.2 RC (27B48) is out: Swift 6.4, iOS 27.2 SDK, needs macOS Tahoe 26.6+.

The headline is .xcproj, a JSON project format Apple calls more readable, merge-friendly and easier for coding agents to edit.

Switch in the File inspector. Earlier Xcode 27 builds still open it.

Mistral's Timestral, Oct 15: time-series foundation models, 5M to 209M params.

209M tops GIFT-Eval, TIME and fev-bench with two-thirds the params of the old leader.

No GPU. On 8 CPU threads a day-ahead forecast takes 10 ms (5M) or 140 ms (209M).

It runs on your metrics box.

Unconfirmed: The Information (Oct 19, paywalled) says Anthropic is prepping a model with more reasoning and "intuition" for vague asks.

Example: asked to fix a bug, it finds the root cause and offers to fix related ones.

Fable or Opus line, unknown.

If true, vague bug reports become fine prompts.

OpenBSD 8.0 is out. Release 61, release song "The Simps on AI".

amd64 kernel VA space goes from 4G to 512G. arm64 gets hibernate. sparc64 moves to the LLVM toolchain.

loongson is dropped because it doesn't work with Clang 22. Loongson machines get no 8.0 build.
