One of Swift's smartest optimizations is also one of its most misunderstood. When you write: var array2 = array1 Swift usually doesn't copy the data immediately. Instead, it uses Copy-on-Write (CoW) and delays the copy until a mutation occurs. This gives us: Value semantics Memory efficiency Better performance Safer code Understanding CoW explains why Swift collections like Array, Dictionary, and…

Most tutorials teach you how to build a button. This post teaches you why the browser renders that button, what happens when a user clicks it on a phone with a 3G connection, and why your rendering strategy choice can make or break a business. Frontend engineering is not the "easy" side of software. It's the side where every millisecond of latency is felt by a real human being, where you ship cod…

What We're Building In the next 5 minutes, you'll build a simple web app that lets users search for clinical trials by condition and phase, display results in cards, and paginate through results. Clinical Trials API is a REST API that wraps ClinicalTrials.gov into a developer-friendly interface. It gives you structured eligibility criteria (parsed into categories like Age, Gender, Condition, Lab …

Here's an interesting class, from a program I wrote: from datetime import ( date , MINYEAR , MAXYEAR , timedelta , ) class DateInterval : BEGINNING_OF_TIME = date ( MINYEAR , 1 , 1 ) END_OF_TIME = date ( MAXYEAR , 12 , 31 ) def __init__ ( self , start = None , end = None ): if start is None : start = self .

I have completed finishing Class 12 (CBSE) and plan to pursue a career in quant finance. I have about 2.5–3.5 months before starting undergrad. I wanted to ask: What should I focus on during this time to build a strong foundation? Which skills (math, programming, stats, etc.) should I prioritize? Any specific resources, projects, or habits that would give me an edge early on? Thanks!

I'd start a new Claude Code session and spend the first ten minutes pasting files. "Here's the API gateway. Here's the user service. The gateway talks to users over HTTP. Users publish to this Kafka topic. The payments service consumes it. The shared types live in this package. Here's the schema." Next day. New session. Same ten minutes. Some days I'd realize halfway through that I'd already burn…

Here’s a natural, human-style Dev.to first post aligned with your tags ( ai, programming, javascript, react ) and your positioning 👇 Why AI-Generated Code Works… Until It Doesn’t (A React Reality Check) AI tools have changed how we write code. You can now spin up a React component, generate API logic, or even scaffold an entire app in minutes. It feels like 80% of the work is done instantly. But …

For the last eighteen months, most of the code shipped by the team I run has been written by agents . That single fact has slowly reshaped every habit I thought I understood about how software actually gets made, and the gap between what Agile assumed in 1999 and what the work looks like now has become too wide to keep quiet about. There is a harder part beneath that gap, which the industry has b…
