Browser-side image processing notes: making photos work as craft grids

I have been working on a small browser-based image workflow recently, and it reminded me how different "make this image look good" is from "make this image usable as structured output."For ordinary image tools, the final result can be a nice bitmap. For craft tools, icon builders, game assets, printable templates, or grid-based editors, the bitmap is only the middle step. The output has to become something a person can read, edit, count, print, or build.That changes the image pipeline. The

I almost leaked my Discord bot's token last month. Here's the tool I built so it never happens again.

So a few weeks back I was working late on a Discord bot project (Node.js, discord.js v14, the usual stack), moving fast, committing every few minutes because that's just how I work when I'm in the zone. At some point I typed git add . without thinking twice, committed, and pushed.Ten minutes later I'm staring at my .env file sitting right there in the GitHub diff. Bot token, MongoDB connection string, all of it, in plain text, in a public repo.I got lucky. Caught it fast, rotated the token immed

You've been deep-cloning objects with a JSON hack. `structuredClone` does it right.

The JSON.parse(JSON.stringify(obj)) incantation is in almost every codebase. It works often enough that most developers have reached for it without a second thought. No imports, no library, a deep clone in one line — memorable and good enough for a decade."Good enough" is doing a lot of work in that sentence. What JSON serialization actually does to your dataJSON.stringify serializes a value to a text string. JSON has a limited type vocabulary: strings, numbers, booleans, null, arrays, and

The Enterprise Software Industry Has Been Solving Yesterday's Problems

For decades, enterprise software had one primary mission:Standardize the business.And to be fair, it succeeded.Processes became consistent.Financial reporting became reliable.Departments gained structure.Large organizations could finally operate at scale.That was exactly what businesses needed.The problem is that today's enterprises aren't asking the same questions they were asking twenty years ago.Back then, the challenge was managing growth.Today, the challenge is adapting to constant change.T

Svelte May 2026 Update: Why Remote Functions and TypeScript 6.0 Matter

As a developer who's been following the Svelte ecosystem, I saw this release and here is what it means for developers like me: the latest update to Svelte brings significant improvements to SvelteKit's remote functions, adds support for TypeScript 6.0, and introduces experimental community plugins in the Svelte CLI. These changes are particularly exciting because they address some of the key areas where Svelte has been evolving to meet the needs of its growing community. Remote Functions in

Why Your iPhone Photos Won't Open on Windows (and the 5-Second Fix)

Your phone saves them as HEIC. Your laptop shrugs. Here's what's actually going on — and how to stop fighting it.About once a week, someone I know forwards me the same panicked message. iPhone in one hand, Windows laptop open in front of them, and a photo called something like IMG_4821.heic that just… won't open. They double-click it. Nothing. They email it to themselves and try again. Same shrug from Windows. By the time they message me, they're half-convinced the photo is corrupted or their la

TypeScript Template Literal Types: Advanced Patterns for String-Safe APIs

TypeScript Template Literal Types: Advanced Patterns for String-Safe APIsMost TypeScript string handling problems stem from treating strings as opaque primitives. Engineers write route handlers that accept string, event emitters that take string, and CSS-in-JS systems that validate nothing until runtime. The cost is runtime exceptions that could have been caught at compile time.Template literal types transform strings from a necessary evil into a type-safe foundation for APIs. This feature

Ditch UI Libraries: Headless Components in React âš¡

The CSS Override NightmareWhen starting a new SaaS project at Smart Tech Devs, developers immediately reach for massive component libraries like Material UI, Ant Design, or Bootstrap. These libraries give you a working dropdown or modal in seconds. However, the architectural debt hits 6 months later when your design team asks you to implement a custom, brand-specific UI.Because standard component libraries couple the logic (state, clicking, keyboard navigation) with the styling (colors, padding,

React displayName Without Strings: A C#-Inspired TypeScript Proxy Trick

It started with a very small problem.In our React component library, we wanted every component to have a nice displayName.So we did the obvious thing:Component.displayName = "Component";Simple. Clear. Boring.And then reality arrived.From time to time, developers renamed components. Maybe Button became IconButton. Maybe UserCard became CustomerCard.But the displayName string?That stayed behind.CustomerCard.displayName = "UserCard";Technically everything still worked.But debugging became slightly

React useObjectUrl Hook: Preview Files & Blobs Without Memory Leaks (2026)

React useObjectUrl Hook: Preview Files & Blobs Without Memory Leaks (2026)A user uploads a dozen images to a gallery editor. Each one gets a live preview via URL.createObjectURL(). The session runs for twenty minutes, previews get swapped as files are added and removed, and the tab's memory usage climbs the entire time — because every createObjectURL() call has to be paired with a revokeObjectURL() call, and that pairing has to survive re-renders, prop changes, and unmounts. Most compo

I built a privacy-first alternative to jwt.io, regex101 and every other dev tool that phones home

The dirty secret of online dev toolsEvery dev tool lives on a different website.jwt.io for JWT decoding.regex101 for regex testing.Some random site for JSON formatting.Another for diff checking.Another for curl → code.Another for SQL formatting.You end up with 10 bookmarks, 10 different UIs, and 10 different servers that just received your most sensitive data — and you never think twice about it.I didn't either.

I made a template for building full-stack app from the stack I keep reusing

Over the past few years I have had to build a few different apps (having no formal CS background), usually some version of a full-stack product with an API, web UI, CLI tooling, packaging, etc.Using the tech stack and the knowledge acquired during the last few years, I have tried to ask Claude to make a reuseable template based on that. Putting it out here, in case it helps anyone.OpenProductKit: github.com/ravipurohit1991/OpenProductKitIt’s a Copier template that generates a product repo with:F

Your Chrome extension needs a privacy policy. Here's one in 2 minutes.

You finished the extension. The listing is written, the screenshots look great, you hit Submit for review - and a few days later the Chrome Web Store rejects it over something that has nothing to do with your code: the privacy policy.It's one of the most common non-code rejection reasons, it blocks Firefox and Edge submissions too, and it's entirely avoidable. This post covers when you actually need a policy, what reviewers look for, and two ways to produce one - by hand, or generated from your
