Wooting’s 60HE v2 isn’t just a terrific Hall Effect keyboard. It’s a fantastic keyboard period.

The Xperia 1 VIII marks an attempt at a step change for Sony's flagship phone line. Not only has it had an aesthetic overhaul, but Sony has also revamped the camera system, dropping the continuous optical zoom telephoto that's defined the last four generations of Xperia phone. It's not all different. Sony staples like a […]

With Apple raising prices soon, you can save a lot of money by buying a used handset or upgrading an older device—safe in the knowledge that it'll last longer than ever.

Error Handling — Learning to Love if err != nil In part 3 I covered goroutines and channels, and how Go's concurrency model sidesteps a lot of the ceremony I was used to from the JVM. This time I'm tackling the thing I complained about in part 1 of this series before I'd even really tried it: error handling. I called if err != nil repetitive back then. A few weeks and a lot of real code later, I owe Go a partial apology. No Exceptions, On Purpose Coming from Java, the absence of try / catch is the first thing that feels like a missing feature. It isn't — it's a deliberate design choice. In Go, errors are just values. A function that can fail returns an error as its last return value, and the caller decides what to do with it, right there, inline: func divide ( a , b float64 ) ( float64 , error ) { if b == 0 { return 0 , errors . New ( "division by zero" ) } return a / b , nil } func main () { result , err := divide ( 10 , 0 ) if err != nil { fmt . Println ( "error:" , err ) return } fmt . Println ( "result:" , result ) } That's the pattern you'll write hundreds of times in Go: call a function, check err , handle it or bail out, move on. No hidden control flow jumping up the call stack to whichever catch block happens to match. No checked-exception signatures cluttering method declarations. No RuntimeException quietly skipping past five layers of code that had no idea it could happen. Whatever can fail is sitting right there in the function signature, and you're forced to look at it. Why the Repetition Is the Point My part 1 complaint was that if err != nil everywhere feels manual. It is manual — and that's exactly the trade Go is making. In Java, an exception thrown deep in a call stack can silently propagate through layers of code that never declared they might fail, and you only find out where things actually break by reading a stack trace after the fact. In Go, every single point where something can go wrong is visible in the source, in order, as you read top to

A great CLAUDE.md is not the longest one. It is the one where every line changes what Claude does. The whole skill is knowing what belongs in it — and, just as importantly, what does not. The sections that earn their place Start with a one or two line project description and your stack, with version numbers. Claude infers a lot from your code, but it will not guess that you are on Next.js 15 instead of 14, or which ORM you chose. Then a directory map — not every file, just the top-level layout with a note on what each part holds. After that: the build and test commands, the conventions a formatter does not enforce, and critically, the things not to touch. # Project: Acme Dashboard Next.js 15 (App Router), TypeScript, Drizzle ORM, Vitest. ## Structure src/app/ # routes and pages src/lib/ # shared utilities, db client db/migrations/ # generated - never hand-edit ## Commands Build: npm run build Test: npm run test ## Conventions - API routes return { data, error } - never throw to client - Server components by default ## Do not touch - db/migrations/ is generated. Never edit by hand. Every line in that file would cause a mistake if removed. That is the bar. What to leave out This is where most files go wrong. Two kinds of content waste your budget: Personality instructions. "Act as a senior engineer," "think step by step," "be thorough." These feel productive but change nothing — Claude already does them. General advice that does not prevent a specific mistake is pure noise. Rules a tool already enforces. If you have a formatter or linter, do not restate what it enforces. Wire it into a hook instead, and keep CLAUDE.md for what tools cannot enforce. The one-line test For every line, ask: "If I remove this, will Claude make a mistake?" If yes, keep it. If no, delete it. This single question, applied ruthlessly, is the difference between a file Claude follows and one it ignores. A bloated file buries the rules that matter in noise, so Claude cannot tell which line is the

If you use Claude Code, there is one file that quietly shapes every session: CLAUDE.md. Most developers either do not have one or have one that works against them. Here is what it actually is, in plain terms. The file Claude reads every session CLAUDE.md is a markdown file that Claude Code reads at the start of every conversation. Think of it as your project's constitution — the source of truth for how your specific repository works. Because Claude reads it every time, you stop re-explaining your stack, your conventions, and your commands on every task. Why it exists Without a CLAUDE.md, every session starts cold. Claude can read your code, but it cannot infer the things that live outside the code: that you are on Next.js 15 and not 14, that a directory is generated and must never be edited, that your team has a particular commit style. You end up explaining these again and again, slightly differently each time, so the output drifts. CLAUDE.md captures that knowledge once, somewhere Claude always sees it. Where it lives, and how to start Put CLAUDE.md in the root of your project. You do not have to write it from a blank page — the /init command analyses your codebase and generates a starter, detecting your build tools, test framework, and existing patterns: $ claude > /init Treat the result as a foundation, not a finished product. The real value comes from refining it as you learn what Claude gets wrong without guidance. What belongs in it A good CLAUDE.md is short and specific: A one-line stack description, with versions — Claude will not guess Next.js 15 over 14 A directory map — the top-level layout and what each part holds The build and test commands The conventions a newcomer could not infer from the code A "do not touch" section — generated files, migrations, protected paths Here is a compact example: # Project: Acme Dashboard Next.js 15 (App Router), TypeScript, Drizzle ORM, Vitest. ## Structure src/app/ # routes and pages db/migrations/ # generated - never h

The Tailwind CSS4 debate is everywhere right now. And honestly? Most people are arguing about the wrong thing. The real question isn't "inline styles vs. utility classes" — it's about where your styling decisions live and who pays the cognitive cost. Let me break down what's actually happening, with real code, real trade-offs, and a clear take at the end. What Changed in Tailwind CSS v4 Tailwind CSS v4 introduced a major shift: CSS-first configuration. Instead of a tailwind.config.js , you define everything in your CSS file using @theme : /* Before (v3) - tailwind.config.js */ module .exports = { theme : { extend : { colors : { brand : '#6366f1' , } , spacing : { 18: '4.5rem', } } } } /* After (v4) - main.css */ @import "tailwindcss" ; @theme { --color-brand : #6366f1 ; --spacing-18 : 4.5rem ; } This is cleaner for many workflows. But it's not what's causing the drama. The Real Flashpoint: Utility Density in JSX What's actually triggering the discourse is how v4 accelerates a pattern that was already polarizing — components that look like this: // The "inline styles but make it Tailwind" pattern function AlertBanner ({ type , message }) { return ( < div className = { ` flex items-center gap-3 px-4 py-3 rounded-lg border ${ type === ' error ' ? ' bg-red-50 border-red-200 text-red-800 ' : ' bg-blue-50 border-blue-200 text-blue-800 ' } ` } > < span className = "text-sm font-medium" > { message } </ span > </ div > ); } vs. the @apply approach many teams prefer: /* alert.css */ .alert { @apply flex items-center gap-3 px-4 py-3 rounded-lg border; } .alert--error { @apply bg-red-50 border-red-200 text-red-800; } .alert--info { @apply bg-blue-50 border-blue-200 text-blue-800; } // Cleaner component function AlertBanner ({ type , message }) { return ( < div className = { `alert alert-- ${ type } ` } > < span className = "text-sm font-medium" > { message } </ span > </ div > ); } Both work. Neither is objectively wrong. But they encode very different philosophies. The Philos
