I read this and I'm terrified, the situation seems intractable.
In the python ecosystem alone every cpython install, venv, UV is at risk.
Don't get my started on npm, pnpm, yarn, go, rust.
My current 2026 security posture: stay home and only connect to the internet from a trusted ISP.
The winter is coming.

Andrew Ng just dropped the best 2-hour course on Graph Engineering: from single agent to full automation
9:14 - your first agent
33:11 - loop engineering
1:02:46 - graph engineering
1:30:15 - agents that rewrite themselves
1:49:05 - full graph system
two hours, and it replaces every agent tutorial you bookmarked this year
Prompts → Agents → Loops → Graphs
most people will stop after the first agent and call it automation
he saves the last forty minutes for the graph that runs it without him
same model, same tokens, completely different week
watch it today

New Fil-C docs just dropped 🔥🔥🔥🔥
If you plan on rewriting a C codebase in Rust for mem safety, give this a read first
I took some time to flesh out the documentation of the Fil-C compiler, with special attention paid to the clang driver changes!

MIT's 6.851: Advanced Data Structures (Spring'21)
courses.csail.mit.edu/6.851/…
This has been on my recommendation list for a while, and the Memory hierarchy discussions are great in the context of cache-oblivious algorithms.
"Cache‑Oblivious Algorithms and Data Structures" by Erik D. Demaine
erikdemaine.org/papers/BRICS…
This is a foundational survey on designing cache‑oblivious algorithms and data structures that perform as well as cache‑aware approaches that require hardcoding cache size (M) and block size (B).
The work helped pave the way for portable performance gains without per‑machine cache tuning.

Python 3.14 is out today! Here are my notes on the new release: simonwillison.net/2025/Oct/8…
If you're an open source library maintainer who supports all current Python releases this also means you can drop 3.9 support now and start depending on features from 3.10, like match/case
