text-to-cad is now on the official codex plugin directory!

here's a fun demo of me using it to design a 3D printed iphone duo stand in about 10 minutes

The @excalidraw mcp is sick.

Have it live draw explanations (with pencil sounds and all) then pop open to the app and make your own changes.

Learning with ai is so fun. (Also, don't stop learning, your brain is too valuable)

Your ad blocker could fit behind your router.

meet ESP32-C3 AdBlock, an open-source DIY DNS ad blocker by ZedAxis, built around a roughly $2 ESP32-C3 Super Mini board

inside: 400 KB of RAM, 4 MB of flash, built-in Wi-Fi and a USB adapter, tucked into a printed case

no subscription

no browser extension

no separate power brick

plug it into your router’s USB port for power, connect over Wi-Fi and set it as your DNS server to block listed ad and tracker domains.

compact 40-bit hashes save RAM. a web dashboard lets you check blocked requests and add domains,

while open-source code and case files let you build your own.

follow for more hardware you can see working

@NealGardner_ more like those who prefer gerard maldini over this beast

We are releasing → https://t.co/9bfbbdJZip today: AI driven embeddable CAD. If you ever enjoyed my OSS projects (zustand, react-spring, r3f, pmndrs), these all came out of CC. 🍻
A small 🇨🇭 team has been working on CAD for so many years, release seemed always out of reach. This is a huge milestone for us and i'd appreciate a RT. 🙏

Nick Nethercote's September compiler performance column is out and buried at the end is the most important line. 🦀

First, the headline numbers. Two months of work, 629 benchmarks measured:
→ Mean wall-time reduction: 4.57%
→ 555 benchmarks improved, 74 regressed
→ Multiple benchmarks saw double-digit reductions

The technical term, in his own words: "a sea of green."

Standout wins:

PGO enabled for Clippy : up to 18% wall-time improvement on some benchmarks.

LLVM 23 upgrade : 1.2% mean wall-time reduction across all benchmarks from a single PR. Small number, huge impact at that scale.

Cranelift-codegen's enormous function. One function, 18,000+ basic blocks. Changing the CFG traversal algorithm dropped calls to apply_effects_in_block from 1.5 million to 90,000. Result: ~30% wall-time reduction for check builds of that crate.

New contributor xmakro had a remarkable run: specialization graph optimization (-1.58% mean cycle count), incremental data loading (-6% best case), allocation reductions in obligations processing, and static dispatch replacing dynamic in trait solver selection.

Polonius Alpha and the new trait solver both landed on nightly this period. Both caused some regressions that are being actively fixed. Jack Huey's liveness optimizations already recovered 3-5% on serde.

And the buried lede: Nick starts working at Hexcat tomorrow, specifically hired to work on compiler performance optimizations full time.

Packed week for Rust. Rustler Weekly is out. 🦀

📊 CSV parsing at 180 GB/s : a VLDB 2026 paper from TUM Munich. 22x faster than DuckDB, 256x faster than single-threaded Rust CSV. Speculative parallel parsing, end-to-end SIMD, zero inter-thread communication.

🔮 fearless_simd v1.0 incoming : SIMD in Rust without writing unsafe. Hardware-width vectors, multiversioning built in, three-year security commitment planned.

🔬 State of SIMD in Rust : the most balanced survey available. Five libraries mapped out. The most actionable detail: put #[multiversion] on loops, use #[inline(always)] for tiny functions.

🚂 Topcoat 0.9 : Rails-style web apps in Rust from the creator of Tokio. Server components, WebSocket push, signal-based reactivity. No API layer, no client state management.

💡 Enum variants as their own types : a short post that will live rent-free in your head. Prove at compile time what kind of value you have. No runtime check, no comment.

🔑 hashify : perfect-hash lookups as a proc macro. 4x faster than phf for tiny maps, 40% faster for large maps. Zero heap allocation.

💼 New Rust jobs added daily : https://t.co/7wifSiZyo1

🗓️ Events : Manchester, Berlin, Munich and more. October kicking off strong.

分享一个怎么绕过 Codex 反编译、逆向道德感的操作

其实也比较容易实现的，你就不要在 prompt 里提什么逆向以及提什么反编译之类的 你就把这个库安装下来后
https://t.co/m5Lxr6Pmk4

就直接跟他说按照这个markdown 去处理某个应用即可https://t.co/JD8Y4MNP6a

要注意的是，不要让 Codex 或者 Claude 去从 0 开始安装上面的 skills，会拒绝

你要自己装，当然你可以 clone 以后，其中一些安装步骤让它来执行

以上我主要在 Codex 验证，Claude 没有做验证，你们可以试试，可以说 Codex 屡试不爽

NEW: Durable Functions in PostgreSQL 🤯

pg_durable is a PostgreSQL extension. The workflow state, queue, retries, and recovery live in Postgres, and it uses Postgres durability / HA / backups / recovery.

@NealGardner_ is there any big match?

[0xdd @_eight_miles]

@NealGardner_ I think de jong will replace martin. and then he will be libero.

[DeepSeek @deepseek_ai]

🚀 Introducing DeepSeek-V4.1-Flash: smarter, faster, more efficient.

🔹 Introducing the smallest model in our new architecture family, with native visual understanding.
🔹 Designed for greater capability, faster inference, higher throughput, and scaling to larger models.

@AMSMayowa @ReshadRahman yep. too many easy mistakes, gordon is more polished and tidy

[0xdd @_eight_miles]

@MOOBAAH_0 @ReshadRahman yup, very chaotic and all over the place. Gordon is more polished

[0xdd @_eight_miles]

@ReshadRahman not that good tbh. very chaotic, all over the place.

[0xdd @_eight_miles]

@mitchellh @mbravo @demfabris you made some secure things but you are not immune to making mistakes

[0xdd @_eight_miles]

@ABadissy @roboflow how accurate?
