**When:** February 19th - 22nd, 2024

**Schedule:** 4 Days/ 4 Hours, from 8am to 12pm EST (GTM - 5)

**Where:** Online - Zoom Meeting

**Description:** The workshop is composed of four 4-hour sessions. It is aimed toward developers who have experience with Go and would like to understand how to write more efficient code and understand data semantics and concurrency patterns. We’ll cover many coding best practices that help write precise code.

#### What a student is expected to learn:

* * *

#### Day 1: Memory & Data Semantics

**Programming vs engineering:**

* Value semantics
* Pointer semantics and Ownership rules

**Stack vs heap allocations and how they affect your code:**

* Detecting and understanding escape analysis

**How the garbage collector (GC) works and its effect on performance:**
*  Common causes for memory leaks

**Writing CPU cache-friendly code:**

**Working with slices in memory efficient way:**
* Range loop semantics

* * *

#### Day 2: Data Oriented Design

**Data-oriented design:**
* Choosing value vs pointer semantics
* Built-in types
* User-defined types

**Polymorphism with interfaces:**
* Modeling interfaces
* How interfaces are implemented understanding cost

**Using embedding: Difference from traditional OO**

**Using generics**
* Generics functions
* Generic data structures

**Method set rules**

* * *

#### Day 3: Concurrency

**The OS scheduler:**
* Design and tradeoffs
* How they affect you

**The Go schedule:**

**CPU vs I/O bound job:s**

**Synchronization and orchestration:**
* Understanding channels
* Using sync and sync/atomic
* Concurrency patterns
* Wait for results
* Fan out
* Polling

* * *

#### Day 4: Performance Optimization

**Before you start optimizing:**

**CPU Profiling:**
* Writing benchmarks
* Using the profiler
* Using the execution traces

**Memory profiling:s**
* Benchmarking memory
* Using the GC tracer
* Using the execution tracer

* * *

#### Prerequisites

You should have experience writing Go code. You should have the following installed on your machine:

* Go SDK
* IDE such as VSCode with the Go extension or Goland
* Git
* graphviz
