Every pull request in your repo should be reviewed. But manual code reviews take time — often 2-4 hours per PR. And reviewers miss things when they are tired or rushed. AI code review tools read every PR automatically and leave comments in minutes. Not replacing human reviewers — augmenting them. The AI catches the obvious bugs, the human reviewer focuses on architecture and business logic. Here is how to set it up on GitHub. Three options — from easiest to most customizable. ...

In Go Tutorial #4, you learned the basics of error handling — the error interface and the if err != nil pattern. Now it is time to go deeper. Real applications need more than basic error checks. You need to know what went wrong, where it went wrong, and how to handle different errors differently. Go gives you tools for all of this. Error Wrapping When a function calls another function and gets an error, you should add context before returning it. Use fmt.Errorf with the %w verb to wrap errors: ...

In the previous tutorial, you learned about channels. Now you will learn how to work with multiple channels at the same time using select, how to cancel operations with context, and some powerful concurrency patterns. These are the tools that make Go concurrency practical for real applications. The select Statement select lets you wait on multiple channel operations at the same time. It blocks until one of the channels is ready: ...

In the previous tutorial, you learned about goroutines. But goroutines alone are not enough. They need a way to communicate. That is what channels are for. Channels are typed pipes that connect goroutines. One goroutine sends a value into the channel, another goroutine receives it. Channels make concurrent programming safe and simple. Go has a famous saying: “Do not communicate by sharing memory. Share memory by communicating.” Channels are how you do that. ...

Most developers use Claude Code like a chatbot. Type a question, get an answer, copy the result. That is maybe 20% of what it can do. Here are 5 tricks that change how you work. 1. The ! Prefix — Run Shell Commands Instantly Type ! before any shell command in the chat and Claude runs it immediately — and reads the output. ! git log --oneline -5 ! npm test ! docker ps ! cat package.json Claude sees the result as part of your conversation. No copy-pasting terminal output into the chat. No switching windows. ...

In the previous tutorial, you learned how to organize a Go project. Now it is time for Go’s most powerful feature — goroutines. Goroutines are lightweight threads managed by the Go runtime. They are the reason Go is so popular for servers, microservices, and concurrent programs. You can run millions of goroutines on a single machine. What is a Goroutine? A goroutine is a function that runs concurrently with other goroutines. You start one with the go keyword: ...

Everyone writes about AI tools. Nobody shows how they actually use them day to day. Here is my real workflow — which tools I open, when I use each one, what works, what fails, and what it actually costs. No sponsored content. Just what I do. My Daily Setup Three screens. Two AI tools always running. One browser tab. Left screen: Cursor (main code editor) Right screen: Terminal with Claude Code Browser: Claude.ai or ChatGPT for quick questions That is it. No 10 tools. No complex setup. Two AI coding tools and a chat window. ...

In the previous tutorial, you learned about pointers. Now it is time to learn how to organize a Go project properly. Good project structure makes your code easy to read, test, and maintain. Go does not force a specific layout, but the community has developed clear conventions. This tutorial teaches you those conventions. Starting Simple — One Package When your project is small, keep it simple. A single main package is fine: ...

In the previous tutorial, you learned about interfaces and polymorphism. Now it is time to learn about pointers — how Go lets you share and modify data efficiently. If you have used C or C++, you know pointers. Go pointers are simpler. There is no pointer arithmetic. You cannot do math on pointer addresses. This makes Go pointers safe and easy to understand. What is a Pointer? A pointer holds the memory address of a value. Instead of copying the value, you pass its address. This lets functions modify the original value: ...

Anthropic launched the Advisor Strategy on April 9, 2026 — a way to get near-Opus intelligence in your AI agents at a fraction of the cost. The idea is simple. Instead of running Opus on every request, you pair a cheaper model with Opus as an on-demand advisor. The cheap model does all the work. Opus only steps in when needed. How It Works You have two roles: Executor — Sonnet or Haiku. Runs every turn. Calls tools, reads results, makes decisions. Advisor — Opus. Runs on-demand only. Reviews the shared context and sends guidance when the executor is stuck. The executor and advisor share the same context: the system prompt, tool definitions, full conversation history, and all prior tool results. When the executor hits a hard decision, it calls the advisor tool. Opus reviews the full context and sends back a plan or correction. Then the executor continues. ...
