When building modern applications, one problem shows up everywhere: How do I uniquely identify data across systems? That’s where UUIDs (Universally Unique Identifiers) come in. A UUID is a 128-bit unique identifier used to identify information in distributed systems. Example: 550e8400-e29b-41d4-a716-446655440000 It looks random - and that’s the point. Traditional IDs (like auto-increment integers
If this is useful, a ❤️ helps others find it. All tests run on an 8-year-old MacBook Air. If a user closes the AI diagnosis overlay and reopens it, should you call Gemini again? No. Cache the result. Same input → same output. No reason to burn rate limit quota. Here's the caching layer I built into HiyokoLogcat. Without caching: User clicks diagnose on error line 847 Gemini responds in 3 seconds U
It happened to me. My site — bashsnippets.xyz — had been down for six hours before I knew That's the kind of thing that sits with you. The fix took 20 minutes to build. Here's exactly what I wrote and why The natural instinct is to just open a browser and load the page. You only check when you remember to You don't check at 2am when it actually goes down What you want is automated, logged, and
In the previous post, I walked through the compensation logic in each service. The code looks clean on paper. But sagas have a lot of moving parts, and bugs tend to hide in the transitions between services, not inside a single service. This post covers how I test the saga system: unit tests for each service, orchestrator routing tests, and the edge cases that caught me off guard. The orchestrator'
"Nobody tells freshers the real numbers. HR says 'competitive salary.' LinkedIn shows fake CTCs. College placement cells lie. This post doesn't." Let me ask you something uncomfortable. 👇 You're about to graduate. You're applying for jobs. You see a role that says "CTC: 6-12 LPA." What does that actually mean for your bank account every month? 🤔 What's the difference between a ₹6 LPA offer in Ba
The Model Context Protocol (MCP) has become the default standard for connecting AI agents to external tools and APIs. Governed by the Linux Foundation since early 2025 and adopted by OpenAI, Anthropic, Microsoft, and Vercel, MCP is the USB-C port of the AI ecosystem — one protocol that lets any LLM application talk to any tool server. But there's a gap between reading the spec and building somethi
Hello Developers! 👋 The tech landscape is shifting faster than ever. What worked in 2023 is already considered legacy, and the way we build software has fundamentally changed. If you want to stay ahead of the curve, build faster, and ship high-converting applications, you need to adapt. Here is a breakdown of the exact trends dominating software engineering in 2026 and how you can implement them
If you have spent any real time with Claude Code, you have probably noticed the same problem I did. You write the same instructions in the prompt every other day. "Use four-space indentation here." "Always run the linter after edits." "Format commit messages this way." After the third or fourth repeat, it stops feeling like a prompt and starts feeling like missing config. Skills are how Claude Cod
