## Coddy

Coddy is a web-based coding education platform built around doing rather than watching. Instead of long video lectures, learners work through short interactive lessons in the browser, then immediately apply what they learned in an integrated playground with a compiler or interpreter. The catalogue spans web development (HTML, CSS, JavaScript, TypeScript, React, Next.js, PHP, Django), general-purpose languages (Python, Java, C#, Go, Ruby, Kotlin, Lua), systems work (C, C++, Rust, Assembly, Verilog, Solidity) and mobile development (Flutter, Dart, Swift, SwiftUI).

Beyond single languages, Coddy organises guided learning paths that mirror real job roles: Software Engineer, Frontend Developer, Full Stack Developer, Backend Developer, Data Analyst, Data Scientist, DevOps Engineer and several game-development tracks for Unity, Godot and Roblox. There are also recently added non-programming subjects such as pre-algebra, algebra, geometry, trigonometry, physics, chemistry and chess, aimed at learners who want one place for both STEM coursework and coding practice.

Coddy can be started for free, and the platform uses a freemium model with premium plans for additional content and features. The site is protected by Cloudflare, so automated crawlers may be blocked while normal browsing works fine. Please check the official pricing page for current plan details, since we do not list prices we could not verify.

**Pricing & Plans:** Free to start with optional paid plans. Coddy uses a freemium structure with premium tiers for extra content, learning paths and playground features; exact current prices should be confirmed on the official pricing page.

- **Interactive lessons in the browser:** Short, practice-first coding lessons that run directly in your browser, so you can start learning without installing a compiler or development environment.
- **Built-in playgrounds and compilers:** Dedicated playgrounds for Python, JavaScript, C, C++, Java, SQL, React, Go, Swift and many other languages let you test snippets and experiment immediately after each lesson.
- **Career-oriented learning paths:** Structured curricula such as Software Engineer, Frontend, Full Stack, Backend, Data Analyst, Data Scientist, DevOps and game development bundle the skills employers actually ask for.
- **Daily challenges and gamification:** Streak-style daily coding challenges and progress tracking help learners build a consistent habit and stay motivated between longer courses.
- **STEM subjects beyond code:** Maths, physics, chemistry and chess courses let learners practise quantitative subjects step by step alongside their programming track.

**Strengths:** Very broad catalogue covering web, systems, mobile, data, game development and even non-programming STEM subjects; No setup required: lessons and playgrounds run entirely in the browser; Guided job-role learning paths make it easier to know what to learn next; Free to start, so you can evaluate the teaching style before paying

**Limitations:** The huge number of tracks can be overwhelming for complete beginners deciding where to begin; Depth per topic may be lighter than a dedicated deep-dive course or textbook; Some premium content requires a paid plan, and pricing must be checked on the site

## Machine learning at scale

Machine Learning at Scale is a newsletter and learning resource published by Ludo, a machine learning engineer at Google. Its stated goal is to help readers become '10x' ML engineers by going beyond introductory tutorials and into the realities of running machine learning in production: how systems are designed, where they break, and which patterns scale.

The content programme is organised around case studies, design patterns, deep dives and career advice. Topics include LLM inference at scale, recommendation systems, search and ranking, RAG in the AI era, and ads systems, alongside coming-soon deep dives into machine learning systems. The author draws on experience fighting abuse at 500k QPS, pretraining and fine-tuning transformer models, working on end-to-end YouTube Ads systems, applying ML at CERN, and a computer-vision thesis at Volvo.

Community and career support are part of the offering: a growing base of ML engineers from leading companies subscribe weekly, and the site includes an FAQ on getting started with ML, getting into big tech, MLE versus data scientist roles, and whether a PhD is necessary. Extra resources include an upcoming MLSys course, a YouTube channel and curated book recommendations.

**Pricing & Plans:** Freemium. The newsletter and much of the resource library (articles, FAQ, career advice) are free to read, with email subscription; the site also references paid offerings such as a course.

- **Case studies and design patterns:** Read breakdowns of ML systems design, LLM inference at scale, recommendation systems, search and ranking, ads systems, and RAG.
- **Weekly newsletter:** Get weekly high-quality insights and practical guidance written by an ML engineer working on large-scale production systems.
- **ML systems deep dives:** Deep dives into LLM optimisation, LLM training and ML system design for engineers moving beyond tutorials.
- **ML career advice and FAQ:** Guidance on getting started in ML, breaking into big tech, choosing between MLE and data scientist paths, and whether a PhD is worth it.
- **Course, YouTube channel and book picks:** Supplement your reading with a dedicated MLSys course, a YouTube channel, curated book recommendations, and ML jobs listings.

**Strengths:** Written by a practising ML engineer at Google; Focuses on production ML systems rather than toy examples; Free weekly newsletter with a large readership of ML engineers; Practical career guidance on breaking into big tech and MLE roles
