Article DEV · 30w Becoming 1% better each day. A developer announces their commitment to a 100-day learning journey focused on frontend development and data structures. They plan to document daily progress through blog posts as an accountability mechanism, learning one topic at a time without rigid planning after previous attempts at structured roadmaps failed. 360 28 2. 2 [](https://daily.dev/posts/i-feel-lost-on-ai-plkcmj7ei "I feel lost on AI") Article DEV · 28w I feel lost on AI A 26-year veteran programmer from Mexico shares his honest emotional struggle with AI coding agents. While he appreciates Copilot as a productivity booster, he feels disoriented and empty when using agentic tools like Claude Code and Amazon Kiro to fully delegate coding tasks. He describes a personal experiment running two projects simultaneously — one coded manually with Copilot, one delegated to Claude Code — and reflects on the tension between efficiency gains and the loss of the craft he loves. The post resonates with many developers who feel the same but rarely admit it publicly. 289 30 3. 3 [](https://daily.dev/posts/the-bug-that-made-me-question-reality-for-a-few-hours-ndxvzfmjj "The Bug That Made Me Question Reality for a Few Hours") Article DEV · 31w The Bug That Made Me Question Reality for a Few Hours A developer shares a debugging story about intermittent production failures caused by a missing environment variable. The issue appeared random because the variable existed locally in a config file but was absent in production, causing inconsistent behavior. The key lesson: bugs that seem random often stem from unvalidated assumptions about environment consistency. The fix involved adding validation and defaults to prevent silent failures. 157 13 4. 4 [](https://daily.dev/posts/i-built-a-saas-in-30-days-here-s-exactly-what-happened--lwkpntyzv "I Built a SaaS in 30 Days. Here’s Exactly What Happened.") Article DEV · 30w I Built a SaaS in 30 Days. Here’s Exactly What Happened. A developer shares their 30-day journey building StackTrace, a log analysis SaaS that converts production logs into readable incident summaries. Starting from zero, they reached 312 signups, 41 paying users, and $1,287 MRR by focusing on solving one specific problem, shipping quickly with a boring tech stack (Next.js, Node.js, PostgreSQL), and iterating based on user feedback. Key lessons include charging from day one, avoiding premature complexity, building only what users request, and being transparent about both successes and failures like churn and pricing experiments. 138 18 [See all DEV archives](/sources/devto/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/devto/best-of/2026/02#page","url":"https://daily.dev/sources/devto/best-of/2026/02","name":"Best DEV Posts — February 2026","description":"The most upvoted DEV posts from February 2026, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/devto/best-of/2026/02#items","numberOfItems":4,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/becoming-1-better-each-day--0fdbkimxw","name":"Becoming 1% better each day."},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/i-feel-lost-on-ai-plkcmj7ei","name":"I feel lost on AI"},{"@type":"ListItem","position":3,"url":"https://daily.dev/posts/the-bug-that-made-me-question-reality-for-a-few-hours-ndxvzfmjj","name":"The Bug That Made Me Question Reality for a Few Hours"},{"@type":"ListItem","position":4,"url":"https://daily.dev/posts/i-built-a-saas-in-30-days-here-s-exactly-what-happened--lwkpntyzv","name":"I Built a SaaS in 30 Days.
