Uploading and Storing Multipart/Form-Data Using Multer and Cloudinary

Introduction When a beginner developer first works with APIs, they tend to focus only on retrieving data or sending text to the server. As they become more comfortable and make more complex requests, they may come across one that requires a particularly annoying content type: multipart/form-data. Multipart/form-data is a type of request content that accepts both file and text data, henc...

AI Is Moving From Finding Bugs to Fixing Them

For twenty years we built better smoke detectors. Now we are finally building firefighters. We have gotten incredibly good at finding problems. Your IDE underlines a vulnerability before you finish typing it. Your CI pipeline fails because a transitive dependency three levels deep has a CVE from 2019. Your inbox gets a Dependabot PR every Tuesday that you will politely ignore until Thursday. Git...

Items in flexbox adding up to more than 100vw on high resolution screens [closed]

I have a webpage with a flex container containing 12 items, displayed in rows of 4. Each item is 25vw wide. On most screens they display correctly as a row of four, but when testing on a larger (higher resolution) screen, it wraps to row of 3. So for some reason they're adding up to more than 100vw. Does anyone know what might be causing this? It doesn't seem to be a browser issue, it's related to...

npm walls off 2FA-bypass tokens from account and package management

A token that skips 2FA is a bad idea (until you need one at 3am) You automate your npm publishes with a token that skips the 2FA prompt, because robots do not punch codes into a phone. Then the token leaks. Now the attacker has your automation, your account settings, your maintainer list, and a fresh batch of tokens they minted for themselves on the way out. Comforting. As of July 31, ...

LLD Data Structures in Design Context: Heap Design Patterns — How Real-World Systems Continuously Choose the Next Best Thing

"Once you understand the behavior a Heap solves, you'll start noticing it everywhere." In the previous article, we learned how to recognize Heap problems. Instead of memorizing examples, we learned to ask: Does this system repeatedly need to choose the best candidate? If the answer is yes, a Heap is often worth considering. Now let's look at how this thinking appears in real software...

I Built a Frontend Skillpack to Reduce AI Coding Agent Token Waste

AI coding agents are not always wasting tokens by writing too much code. In frontend projects, they often waste tokens by reading too much context. A small UI fix can turn into this: "Fix one button" → read the whole app directory → inspect many unrelated components → create a new helper → start a refactor → run out of useful context before QA That is the problem I wanted to solve. S...

How to Generate requirements.txt From What Your Code Actually Imports (pipreqs vs pip freeze)

There's a file in most Python projects that everyone commits and nobody reads, and for two years ours was quietly lying to us. If you've ever wondered how to generate a requirements.txt that reflects what your code actually needs - rather than every stray package that ever wandered into your virtualenv - this is the story of how I finally stopped trusting pip freeze for that job and switched to pi...

Local Kubernetes Dev — Part 4: Setting up your workstation

Before we build clusters and write manifests — let's install the tools and prove they actually work together. Part four of the local Kubernetes series is the hands-on one: we install Docker, kubectl, k3d, helm, and Tilt on macOS, Linux, and Windows+WSL2, add k9s, and — most importantly — run a smoke test that proves the whole Docker → k3d → kubectl chain works end to end. Most guides tell you how...

Generate a QR Code for Every Preview Deployment

A preview URL is only useful when somebody can open it. That sounds obvious, but it is a recurring friction point in reviews. A developer posts a link in a pull request. Someone opens the PR on a phone, copies the URL, switches apps, pastes it, and hopes the preview still exists. The link is correct, but the path to it is needlessly long. A QR code is a small improvement here: generate one along...

LLD Data Structures in Design Context: Recognizing Heap Problems Before Writing Code

"Experienced engineers don't memorize data structures—they recognize patterns." By now, we've learned: what a Heap is, why it exists, and why engineers don't sort everything. But knowing how a Heap works is only half the journey. The real skill is recognizing when a Heap is the right solution. This is exactly what interviewers look for during Low-Level Design interviews. They rarely ask:...

AI Doesn't Ship Software. You Still Do.

AI made the easy 90% of software instant. The hard 90% is still yours. You type one sentence into a prompt box. Ninety seconds later, there's a running app. A form. A database. A chart that updates when you submit it. It looks done. It isn't. Open two browser tabs. Log in as the same user in both. Submit the same form twice, fast — the way a nervous user does when the button doesn't visibly r...

The Real Reason Your Climate Data Project Is Taking Forever
