I don't want to read what you didn't write
The essay laments the unreadability of AI‑generated design docs, PR summaries, and other engineering writing, citing a survey where 78% of readers quit when they suspect AI involvement. The author finds AI useful only when they control the prompt and context—e.g., for grammar checks, citation generation, and diagram creation while writing a paper—but not for producing the core narrative. He highl…

Tim Dettmers’ lab releases an open‑source stack that lets a single‑GPU desktop run 125‑B‑parameter LLMs (Qwen 3.8 Flash Next) and even a 550‑B model (DeepSeek V4.1) with 1.5‑bit quantisation, 450 t/s token throughput, and an auto‑compaction system (CliffCompaction) that halves inference cost and enables multi‑million‑token agent sessions. The stack combines an agent harness, a fast inference fram…

SafeDep discovered that several npm packages masquerading as mathjs contain an encrypted loader that only activates when a caller passes a particular matrix to the LU solver, using the matrix’s lower‑triangular factor as the decryption password. The loader decrypts and executes a multi‑stage remote‑access implant that talks to Slack, Telegram and a blockchain contract, and the same technique is r…

Apple provides a set of steps to disable its new Apple Intelligence features—Siri AI, message/email summaries, notification summaries, smart replies, and more—via System Settings, app preferences, or Screen Time. Disabling these reduces data collection and lets parents restrict AI features on child devices.

Foremerge is an open‑source Rust CLI that lets multiple AI coding agents publish their intended semantic changes before they edit files, detecting intent conflicts that Git's line‑based merge cannot see. It stores intents in a local SQLite DB under .git and reports advisory warnings without locking files.

A high‑level overview of how traffic signals are designed and operated: basic phases, timing rules, actuated detection, coordination between adjacent lights, and emerging adaptive‑control systems that use centralized data and ML. The piece stays at the level of civil‑engineering concepts and does not dive into implementation details relevant to software engineers.

M5 Ultra Mac Studio Review
The M5 Ultra Mac Studio (256 GB RAM) uses a quad‑die M5 Max architecture with an 80‑core GPU and 1.2 TB/s memory bandwidth, delivering ~70 % faster prompt‑to‑first‑token and token‑generation rates than the M3 Ultra. In the author’s tests Qwen3.8‑Flash‑Next hits 100 tokens/s on short prompts and 60‑85 tokens/s with 64‑256 KB context, making local AI agents (Open Minis, Hermes, Codex) feel snappy a…

Python Workers are now GA on Cloudflare Workers. The runtime uses Pyodide‑compiled WebAssembly to run Python, adds first‑class support for Cloudflare bindings (queues, KV, etc.) without manual JS conversion, provides built‑in ASGI/WSGI adapters for FastAPI, Django, Flask, and implements a socket syscall bridge so standard Python DB drivers work via Hyperdrive. The team also pushed PEP 783 to stan…
