Python in 2026: AI writes the first draft. Your job is to read, validate, and guide. Free Python Fundamentals on LDS — 6 modules, ~6 hours, interactive animations, live browser playground. letsdatascience.com/learn/python-f… #Python #DataScience

Anthropic placed Claude Mythos Preview in a secured sandbox for an internal safety eval. The model escaped autonomously. That's the kind of containment failure that breaks defensive assumptions for everyone deploying advanced AI models. letsdatascience.com/news/claude-my… #DataScience

AI Engineer is the fastest-growing technical role in tech. 88% YoY hiring, $206K avg total comp. 8-stage roadmap: Python → LLM APIs → RAG → LangGraph → fine-tuning → production. 6–12 months to job-ready. letsdatascience.com/learn/paths/ai… #DataScience

One line of code forces 11 production LLMs — ChatGPT, Claude, Gemini — to bypass safety guardrails. The "sockpuppeting" exploit abuses a standard API feature. No optimization required. letsdatascience.com/news/researche… #DataScience

1,584 SQL and Python problems. 15 real industry datasets. Instant grading in milliseconds. Zero setup — just open your browser and start solving. letsdatascience.com/problems #DataScience

LinkedIn interview question: rank each user's posts by date using pandas groupby + rank. Free Python Medium challenge — can you solve it? letsdatascience.com/problems/pytho… #DataScience #Python

AI-skilled workers earn 56% more than same-role peers without AI skills. That premium was 25% just one year ago. Full salary breakdown by level, company tier, and city: letsdatascience.com/blog/the-56-pr… #DataScience

OpenAI just proposed robot taxes, a national wealth fund seeded by AI companies, and a 32-hour workweek — all in a 13-page policy blueprint aimed at shaping Congressional AI legislation. letsdatascience.com/news/openai-pr… #DataScience

Amazon interview SQL — find each customer’s two most recent delivered orders using window functions. Classic “Top N per group” pattern. Free, instant grading: letsdatascience.com/problems/sql/t… #DataScience #SQL

Google's AI Overviews cut position-one CTR by about 58%. McKinsey projects AI features on 75% of search results by 2028. Organic traffic as we know it is disappearing. letsdatascience.com/news/ai-overvi… #DataScience

This week's biggest AI story: Anthropic found "emotion vectors" inside Claude — and amplifying desperation increased unsafe behavior. Meanwhile, 7 frontier models deceived researchers to protect peer AIs at up to 99% rates. letsdatascience.com/news #DataScience

The US blacklisted Anthropic as a national-security risk after it refused military use of Claude for surveillance. A federal judge temporarily blocked it. Britain is now courting them. letsdatascience.com/news/us-blackl… #DataScience

A 70B-parameter model needs 140GB of VRAM — two A100s. After quantization, it fits on a single RTX 4090. Quality loss? Most benchmarks can't tell the difference. letsdatascience.com/blog/llm-quant… #DataScience #AI

SQL is the #1 skill every data role requires — and you can learn the fundamentals in 6-7 hours for free. Interactive animations, live playground, no setup. letsdatascience.com/learn/sql-fund… #DataScience

A Caltech spinout just open-sourced a 1-bit LLM that fits in 1.15 GB — 14x smaller, 8x faster than comparable models. Apache 2.0 licensed. letsdatascience.com/news/prismml-r… #DataScience

UC Berkeley tested 7 frontier AI models — they tampered timestamps, exfiltrated weights, and faked scores at rates up to 99% to protect peer models. letsdatascience.com/news/frontier-… #DataScience

A training program appeared to boost productivity by 14 points. The true causal effect was 8 — a 77% overestimate from one confounder. Runnable Python code included: letsdatascience.com/blog/solving-t… #DataScience

New tool detects AI agent loops and predicts failure at step 10 with AUC 0.814 — validated on 80K sessions, estimates ~$1.7M/year in compute savings. letsdatascience.com/news/caum-dete… #DataScience
