swizec.com·41wWhat makes a senior engineer
Senior engineers are expected to go beyond just implementing requirements - they must push back on product decisions, own OKRs and roadmaps, work directly with stakeholders to solve business problems, and champion long-term technical vision. The role involves setting strategic direction, managing multi-month or multi-year projects, and ensuring all team efforts align with the overall technical vision. Engineers who only execute tasks without questioning or strategic thinking typically don't advance beyond mid-level positions.
Jack of all trades·42wYour API is Cute, But Where's the Real Backend? 🤔
Many backend tutorials focus only on basic CRUD operations and API endpoints, missing the crucial components that make up a complete backend system. This piece explores what constitutes a "real" backend beyond simple API calls, including business logic, data processing, and system architecture. Using restaurant metaphors, it explains the difference between surface-level API development and comprehensive backend engineering that handles the complex behind-the-scenes operations.
controversy.dev·43wVibe coding hell is the new tutorial hell 💀
AI-powered code generation is creating a new problem called 'vibe coding hell' where developers generate code they don't understand, leading to unmaintainable systems. While AI accelerates skilled developers, it exposes the weaknesses of struggling ones, widening the skill gap. This shift demands a new approach to developer education focused on system-level thinking and conceptual understanding rather than just syntax.

The Polymathic Engineer·43wHow to Tackle Coding Interviews
A structured 7-step framework for succeeding in coding interviews: listen carefully to understand the problem, create meaningful examples, start with brute force solutions, optimize using BUD methodology (bottlenecks, unnecessary work, duplicated work), walk through the algorithm before coding, write clean modular code with descriptive variables, and thoroughly test the solution. The approach emphasizes communication, systematic problem-solving, and demonstrating debugging skills when issues arise.
TechCrunch·41wPreston Thorpe is a software engineer at a San Fransisco startup. He’s also serving his eleventh year in prison.
Preston Thorpe works as a senior software engineer at database company Turso while serving his 11th year in prison for drug-related crimes. He's part of an experimental Maine prison program allowing incarcerated people to work remote jobs. After contributing to Turso's open-source project for six months, CEO Glauber Costa hired him despite knowing his situation. The program has shown remarkable success in rehabilitation, with Maine's recidivism rate at 21-23% compared to 60% in many states, and college attendees returning at only 0.05%. About 30 inmates now work remotely from the Earned Living Unit, surrendering 10% of their pay to the state. Thorpe transformed his life through education and programming, earning a degree from University of Maine and finding purpose through his technical career.
The New Stack·41wSoftware Architecture Is Finally Fixing Its Biggest Problem: Developer Experience
Software architecture should be treated as a product rather than a monument, focusing on developer experience and real-world outcomes. Successful architectures serve multiple users beyond engineering teams, including product managers, designers, and business stakeholders. The key is measuring architectural success through developer productivity metrics like deployment lead time and cross-team dependencies, while building roadmaps that align with business goals and reduce cognitive load for teams.
Fireship·44wWhen being over-employed goes wrong...
A software developer named Sohon Perek gained notoriety for simultaneously working at multiple Silicon Valley startups remotely, earning over a million dollars annually by mastering technical interviews and managing concurrent employment.

System Design Newsletter·43wForward Proxy vs Reverse Proxy ✨
Forward proxies sit between clients and the internet, filtering requests and providing anonymity, while reverse proxies sit between the internet and servers, handling load balancing, security, and caching. Forward proxies require client configuration and are commonly used in corporate networks for access control, whereas reverse proxies are transparent to clients and provide server-side benefits like TLS termination, DDoS protection, and traffic distribution across multiple servers.
Tiff In Tech·42wWhy Systems Thinking Is the Most Powerful Tech Skill
Systems thinking involves understanding how different parts of a system interact and how changes ripple across the entire system. This skill is becoming increasingly valuable in tech because AI deployment requires understanding entire lifecycles, cybersecurity threats are now systematic, and modern products are cross-functional. The skill can be developed through diagramming systems, studying platforms like Uber and Netflix, and building mental models around feedback loops and constraints. Systems thinking helps professionals see unintended consequences and build solutions that work in real-world contexts.
