I built an interactive guide on how Shazam (the music identification app) works! This is the next installment in my newly coined "How The Heck?" series, where we explore everyday tech that can feel like magic (QR Codes, GPS, and now this one). Hope you enjoy it! perthirtysix.com/how-the-heck...

Just how powerful is this thing?

if err != nil appears so often in Go code that it starts to feel like noise. It isn't. It's Go's deliberate choice to make failure visible — no exceptions, no hidden control flow, just an explicit check at every step. slashstar.store/blogs/code-c... #golang #programming

Real syntax. No jokes. C++, Go, Rust, Python and more — developer t-shirts that speak for themselves. slashstar.store/collections/all #programming #developerlife

Every executable Go program starts with package main. It's not convention — it's a requirement. Understanding why tells you something about how Go thinks about package structure. slashstar.store/blogs/code-c... #golang #programming

A goroutine starts with two words: go func(). Lightweight, cheap to create, multiplexed across threads by the runtime. Go's concurrency model doesn't ask you to think about threads. It asks you to think about coordination. slashstar.store/blogs/code-c... #golang #concurrency #programming

Go's error handling, on a t-shirt. if err != nil — because ignoring errors is someone else's problem. slashstar.store/products/if-... #golang #developerlife

<-chan restricts a channel to receive-only. A small constraint with a clear purpose: it makes the direction of data flow explicit in the function signature, before you've read a single line of the body. slashstar.store/blogs/code-c... #golang #concurrency #programming

std::vector is the container you reach for by default in C++. Not because it's always the right choice — but because it usually is, and it handles memory so you don't have to. #cpp #cplusplus #programming

std::vector in C++: The Dynamic Array You Actually Use

Master std::vector in C++. Learn when to use vector vs array, common methods, performance characteristics, and why vector is the go-to dynamic container.

Templates let you write code that works with any type. They're powerful, sometimes overused, and essential to modern C++. The hard part isn't the syntax. It's knowing when to reach for them. #cpp #cplusplus #programming

C++ Templates: Understanding template

Understand C++ templates and the template syntax. Learn the difference between typename and class, when to use templates, and practical examples.

#pragma once and #ifndef do the same job. One is a compiler extension — widely supported but technically non-standard. The other is portable, verbose, and guaranteed by the spec. Which you reach for says something about how you think about portability. slashstar.store/blogs/code-c... #cpp

argv is just a pointer to an array of strings. The signature is compact, the concept is simple — but understanding it properly changes how you think about memory in C. #C #cprogramming #programming

Command Line Arguments in C: Mastering char *argv[]

Master argc and argv in C. Learn how char *argv[] works, parse command line arguments, and handle user input from the terminal safely.

typedef struct doesn't change what a struct does. It changes how you refer to it. In a large C codebase, that distinction matters more than it sounds. #C #cprogramming #programming

typedef struct in C: Creating Custom Data Types

Understand typedef struct in C. Learn how it simplifies structs, differences vs plain struct, and practical examples for cleaner custom types.

C didn't arrive with a manifesto. It just did the work. Decades later it still runs operating systems, embedded systems, and the runtimes beneath most modern languages. Some things don't need replacing. #C #programming #cprogramming

Why C Still Matters (And Probably Always Will)

C powers Linux, embedded systems, and most language runtimes. Here's why it remains essential for developers who care about performance and control.

#include <stdio.h> is so ubiquitous it stops registering. But it's worth understanding what it actually provides — and why it's usually the first line a C program ever has. #C #cprogramming #programming

#include : The Foundation of C Input/Output

Learn what stdio.h does in C, what functions it provides (printf, scanf, fopen), and why it’s essential for reliable input/output.

std::cout is how C++ talks to the terminal. It looks simple. But understanding the stream insertion operator, null character handling, and how iostream actually works gives you a more honest picture of I/O in C++. slashstar.store/blogs/code-c...

CSS is declarative. You describe intent. The browser negotiates the result. That's why centering a div can feel unreliable — you're not giving instructions, you're making a suggestion. #css #webdev #frontend

Why CSS Feels Harder Than It Should (And What You're Actually Fighting

CSS looks simple until you hit specificity conflicts, margin collapse, and box model quirks. Here's why it feels harder than it should—and what you're actually fighting.

Go code doesn't try to impress. Short names, explicit error handling, no hidden control flow. Just logic that reads top to bottom. The plainness isn't a limitation. It's a decision. #golang #programming

When Go Code Looks Boring (And Why That’s the Point)

Go's design favors clarity over cleverness—explicit error handling, gofmt, and readable code. Here's why boring is actually the point.
