Building isn’t just about writing code — it’s about solving real problems. Yesterday was one of those days where debugging took longer than development, but the learning was worth it. Every bug fixed is a step closer to becoming a better developer. Consistency > Perfection 🚀 #DeveloperLife #CodingJourney #ProblemSolving #Tech

Coding agents have created a whole lot of opportunities to cheaply build efficient dev workflows on top of strong foundations. One example is that you can use them to help you optimize other agents.

Claude Code offers a comprehensive toolkit with 16 sections that cover everything developers need. Many of us utilize only about 10% of Claude Code's capabilities. They are familiar with commands like /help and @file, but often overlook features such as Plan Mode, subagents, hooks, and the /rewind command, which can undo a half-broken refactor without resorting to git reset. To assist, I created a one-page cheatsheet that highlights the essential elements for production: - Install instructions, CLI flags, and all built-in slash commands - Keyboard shortcuts and the three modes: Normal, Auto-Accept, and Plan - Extended Thinking: managing think and ultrathink budgets - Checkpointing and /rewind, including the bash caveat that often confuses users - CLAUDE.md memory and .claude/settings.json permissions - Custom slash commands, Skills, Subagents, and Hooks - MCP servers, cost tracking, and model routing - Eight pro recipes that would have been beneficial from day one Save this cheatsheet and keep it handy next to your terminal. Share it with any developers on your team who are still typing prompts into the chat box. What’s your most-used Claude Code command?

Claude Code is getting seriously wild 🤯⚡ These 6 power moves make the terminal feel way smarter: 1. /batch for parallel work 2. CLAUDE.md for project memory 3. git worktrees for multitasking 4. voice-first coding 5. Dispatch API for background jobs 6. autonomous goal execution What I love most is how this points to the future of faster builds, cleaner workflows, and way less repetitive work. That’s the kind of innovation I’m always here for! 🚀 Which one would you try first? #ClaudeCode #AItools #WebDevelopment #Productivity #DevTools

If you have seen the solution directly before giving 15-20 mins thought to a DSA problem, Congratulations, my friend, you have wasted a DSA problem successfully. Problem-solving is not about successfully submitted solutions on LeetCode or Codeforces; it is about developing a way of thinking with given tools under some constraints.

We're shipping a new /init in the next opencode release. It reads your repo before it asks you anything. Figures out what agents actually need, build commands, project conventions, the stuff that's not obvious from a glance. Then asks a small number of targeted questions to fill in the gaps it can't infer. The output is an AGENTS.md that's actually grounded in your codebase. It's not a generic template; you'll need to rewrite it from scratch. Guided setup that does its homework first.

There's a tweet making the rounds claiming that "Software used to be gated by roughly 20 million professional developers up until last year." I can see how it might seem that way: we refer to the way we write software as "code" as though it's meant to be arcane and inaccessible. But I promise if you are not a developer and you want to learn, you will find plenty of people who would be stoked to help you!

#DevNotesWithVishal – Day 3 One thing that significantly improved my development skills over time: 👉 Learning how to debug effectively. Early in my career, whenever something broke, my first instinct was to rewrite the code or try random fixes. It worked sometimes… but most of the time, it just wasted hours. Over time, I changed my approach. Here’s what actually helped me: Start with understanding the issue, not fixing it Instead of jumping to solutions, I now focus on reproducing the problem and understanding why it’s happening. Break the problem into smaller parts Rather than looking at the whole system, I isolate the issue step by step — frontend, API, or database. Logs are your best friend Adding proper logs (especially in backend flows) makes debugging much faster and clearer. Read error messages carefully Most of the time, the answer is already there — we just ignore it and start guessing. Avoid random changes Trial-and-error without direction only creates more confusion. A structured approach always saves time. Biggest takeaway: Good debugging is not about knowing all answers — it’s about asking the right questions. Debugging used to frustrate me. Now, it’s one of the most valuable skills I rely on daily. Curious to know — how do you usually approach debugging? #DevNotesWithVishal #Debugging #SoftwareEngineering #FullStackDeveloper #LearningInPublic

What users see vs what developers actually do 👀 Like an iceberg 🧊, what users see is only the surface. Everyone sees the login screen. Few see the thousands of lines behind it. Behind every "simple feature" is: • Hours of debugging 🐞 • Endless testing 🧪 • Learning something new 📚 • Fixing what broke yesterday 🔧 Development is like an iceberg small on the surface, massive underneath. Development is not just typing code. It’s solving problems nobody else sees. #Developers #SoftwareDevelopment #Debugging #TechLife #BuildInPublic

The biggest mistake I made as a developer? Thinking about writing code = being a good developer. It’s not. What actually matters: → How you structure your code → How you handle edge cases → How your system behaves under load → How easy it is for others to understand your work Anyone can make things work. Not everyone can make things scalable and maintainable. That’s the level I’m working towards now.
