The platform has evolved to include structured learning paths, in-browser editors, and progress tracking while maintaining its focus on teaching fundamentals. In an era of AI-generated code, understanding how to read code and reason through problems remains crucial, making platforms that teach core concepts more relevant than ever. 832 65 2. 2 [](https://daily.dev/posts/fjpxeu3ai) Article Amit Gajare · 36w 806 42 3. 3 [](https://daily.dev/posts/i-replaced-redis-with-postgresql-and-it-s-faster--x7d3o8vu2 "I Replaced Redis with PostgreSQL (And It's Faster)") Article Lobsters · 34w I Replaced Redis with PostgreSQL (And It's Faster) PostgreSQL can replace Redis for caching, pub/sub, job queues, and sessions using UNLOGGED tables, LISTEN/NOTIFY, SKIP LOCKED, and JSONB. While PostgreSQL is 50-158% slower per operation (0.1-1ms difference), it eliminates network hops between databases, reduces infrastructure costs by \~$100/month, simplifies operations, and guarantees transactional consistency. The approach works best for small-to-medium apps with simple caching needs but isn't suitable for high-throughput scenarios (100k+ ops/sec) or applications requiring Redis-specific data structures like sorted sets or HyperLogLog. 743 61 4. 4 [](https://daily.dev/posts/it-worked-in-dev-it-worked-in-qa-then-production-happened--hw3se8sih "It Worked in Dev. It Worked in QA. Then Production Happened.") Article Developer's Journey · 34w It Worked in Dev. It Worked in QA. Then Production Happened. A backend engineer shares a production incident where an appointment-fetching endpoint worked fine in dev and QA but caused 4-second response times in production. The issue was an N+1 query problem: the code made 6,000+ individual database calls to fetch patient details. The solution involved batching patient data retrieval into a single query using in-memory maps and adding proper projections, reducing latency to 500-600ms. The incident highlights the importance of testing with realistic data volumes, thorough code reviews, and anticipating edge cases during development. 617 61 5. 5 [](https://daily.dev/posts/introducing-the-geolocation-html-element-klyhhpdxd "Introducing the HTML element") Article Chrome Developers · 34w Introducing the HTML element Chrome 144 introduces the \`\` HTML element, a declarative alternative to the JavaScript Geolocation API. This element requires user interaction (clicking a button) to request location data, reducing accidental blocks and browser interventions. It evolved from a generic \`\` element after origin trial feedback showed improved user trust and success rates. The element simplifies implementation by handling permission states automatically, supports attributes like \`autolocate\` and \`watch\`, and includes styling constraints to prevent deceptive patterns. A polyfill and progressive enhancement strategies ensure backward compatibility with browsers that don't support the new element. 589 24 6. 6 [](https://daily.dev/posts/wkwv9heyf) Article Web Nepal · 34w 496 22 7. 7 [](https://daily.dev/posts/introducing-postgres-best-practices-oieboe2rs "Introducing: Postgres Best Practices") Article Supabase · 33w Introducing: Postgres Best Practices Supabase released Agent Skills for Postgres Best Practices, a collection of 30 rules across 8 categories to help AI coding agents write correct, performant Postgres code. The rules follow the Agent Skills open standard and cover critical areas like query performance, connection management, Row Level Security, schema design, and concurrency. The repository addresses common mistakes seen across hundreds of thousands of Postgres projects, such as missing indexes, RLS bypasses, and connection pool exhaustion. These best practices complement the Supabase MCP server by teaching agents proper judgment while the MCP server handles database connections and execution. 493 8 8. 8 [](https://daily.dev/posts/what-is-your-most-used-design-pattern-acjvt58qy "What is your most used design pattern") Article Krzysztof · 34w What is your most used design pattern A developer shares their experience with design patterns, noting that while many patterns exist, few are commonly implemented in practice. The Singleton pattern stands out as their most frequently used pattern, first encountered while working with Unity Engine for managing shared state across scenes, and later applied across various technologies including Java and TypeScript. The post invites others to share their most commonly used design patterns. 440 68 9. 9 [](https://daily.dev/posts/do-not-give-up-your-brain-jb9xoabfe "Do not give up your brain") Article Cassidy's blog · 34w Do not give up your brain While AI tools like ChatGPT can be valuable assistants, over-reliance on them for basic tasks like writing emails or generating responses can atrophy critical thinking skills. People who depend on AI for communication often struggle in real-time conversations. Maintaining mental sharpness requires actively using your brain rather than defaulting to AI for every task. The key is treating AI as a tool to augment thinking, not replace it. 439 35 10. 10 [](https://daily.dev/posts/microservices-are-killing-your-performance-and-here-s-the-math--oc7oxm66d "Microservices Are Killing Your Performance (And Here's the Math)") Article DEV · 34w Microservices Are Killing Your Performance (And Here's the Math) Microservices introduce significant performance overhead compared to monolithic architectures. Network calls add 1,000-5,000x latency versus in-process function calls, resulting in 50-150% higher latency, 300% more resource usage, and 2-3x infrastructure costs. Benchmarks show microservices suffer from cascading failures (5x more downtime), database connection exhaustion, and serialization overhead. The article argues microservices solve organizational problems (team autonomy, independent deployment) rather than technical ones, and recommends modular monoliths for most applications. Microservices only make sense for organizations with 50+ engineers, independent scaling requirements, technology diversity needs, or compliance isolation. 435 39 11. 11 [](https://daily.dev/posts/your-year-wrapped--zko6xwdrp "Your year.

Here’s why.") Article Tech World With Milan · 32w You can code only 4 hours per day. Here’s why. Research shows developers can only sustain 3-4 hours of deep, focused coding per day due to cognitive limits. Studies reveal the median developer codes just 52 minutes daily, with 11+ hours weekly consumed by meetings. Interruptions cost 23+ minutes to recover from, and achieving flow state requires 15-25 uninterrupted minutes. Practical strategies include time-blocking, eliminating context switching, protecting morning hours, and setting no-meeting days. AI coding assistants don't extend deep work capacity but can handle shallow tasks. Engineering managers should prioritize removing meetings over adding processes to maximize team productivity. 422 26 13. 13 [](https://daily.dev/posts/i-m-brave-enough-to-say-it-linux-is-good-now-and-if-you-want-to-feel-like-you-actually-own-your-pc-a9frwtg9n "I'm brave enough to say it: Linux is good now, and if you want to feel like you actually own your PC, make 2026 the year of Linux on (your) desktop") Article Hacker News · 36w I'm brave enough to say it: Linux is good now, and if you want to feel like you actually own your PC, make 2026 the year of Linux on (your) desktop Linux has become genuinely user-friendly for desktop use, especially for gaming. Distros like Bazzite make it easy to run games without command-line knowledge, often matching or exceeding Windows performance through Valve's Proton. Steam's Linux user base hit 3.2%, surpassing Mac. The main appeal is ownership and control—no forced AI features, bloatware, or upselling. While HDR support and some anticheat software remain issues, they're improving. Linux offers a viable alternative for users tired of Windows feeling like rented software rather than something they truly own. 396 62 14. 14 [](https://daily.dev/posts/claude-the-1-ai-for-programmers--r3l7p78tu "Claude: the #1 AI for programmers?")
