Hold an iPhone near a sticker and something happens. A business card lands in your contacts, a focus session ends, or a door opens. The chip costs about twenty pence and holds roughly a hundred and th

Some time ago, I gave a machine learning model five columns from a public CDC dataset and asked it to predict a sixth column from the same file. The model scored an R² of 0.998, which is about as clos

Somewhere in your company's ServiceNow instance is the answer to the question an engineer asks at two in the morning: if this is broken, what else is about to break? Every fact needed to answer it has

AI coding assistants have become really good at fixing code. Paste an error into an AI tool and, within seconds, you'll get a corrected implementation. That's useful when you simply want to get someth

A radiologist can mark a tumor on a CT scan by drawing a straight line across it. Creating a complete 3D segmentation requires outlining the tumor across the slices where it appears, which is more tim

High-resolution images look great, but they can significantly slow down page load times and consume massive amounts of storage. While backend compression tools are common, building a client-side image

Your workflow uses actions/checkout@v4. Today, that tag points to a vetted release. Tomorrow, a compromised maintainer or attacker moves the tag to malicious code. Your pipeline runs it with access to

Large legacy migrations often fail long before the final cutover. The failure usually starts when the migration is framed as a single event. Move the application. Move the database. Move all the users

Geoffrey Hinton is known as the "the Godfather of AI". We just published a course on the freeCodeCamp.org YouTube channel that will help you master modern neural networks by recreating the groundbreak

Taking a web application from local development to a live, secure production environment can be daunting if you've never looked under the hood. We just published a comprehensive course on the freeCode

macOS 27 Golden Gate is here. Apple released it September 14, 2026, as a free upgrade for every Mac that can run it. I'll show you what actually changes for developers in macOS 27, how to upgrade with

A developer's laptop holds more sensitive data than most people realize: API keys, database credentials, staging environment secrets, and sometimes entire copies of production data pulled down "just f

Your online presence often gives potential employers, clients, partners, and recruiters their first impression of you. It's likely what they see before they ever meet you. They search your name, read

A Linux kernel module is a small piece of code that can be loaded into the running kernel without rebuilding the entire kernel. That sounds simple enough, but even a minimal module produces a surprisi

Web Real-Time Communication (or WebRTC) is the open standard browsers use to send audio, video, and data straight to each other. There's no plugin or native app, nothing beyond an API that every brows

Security reviews are most effective when developers receive feedback while the code is still fresh in their minds. Waiting until a pull request, CI build, or penetration test to find exposed credentia

American shoppers spent about $29 billion on gift cards over the 2025 holiday season, and 43 percent of them bought at least one. This put gift cards at the top of what people said they wanted accordi

Feature flags are one of the most powerful tools in a team's deployment arsenal. They decouple deployment from release, meaning your CI/CD pipeline can push code to production servers on every merge,

The most dangerous moment in a legacy migration isn't necessarily when you start writing the new implementation. It's when the new implementation looks finished. The code compiles, the tests pass, the

Here's a program restricting itself, then trying to read two files: without landlock: read /etc/hostname ok read /tmp/secret.txt ok with landlock, /etc allowed: read

Your Apple Watch can tell you how fast you're moving, how your heart responds to exercise, and how your workout changes over time. But one of its more interesting fitness metrics is something it can't

Let's say you have enough credit left to generate one more image in an AI app. You submit a request in one browser tab, then submit another in a second tab before the first finishes. The app accepts b

If you write software for anyone who pays UK tax, sooner or later you'll need to talk to HMRC. Making Tax Digital (MTD) for Income Tax went live on 6 April 2026, and it's already mandatory for self-em

On August 13, 2026, DeepSeek published a GitHub repository called deepseek-harness. Within two days, it had passed 95,386 stars and 8,826 forks (a vanity metric on its own, but a spike this fast signa

Almost everyone has snapped two LEGO bricks together at some point, even without owning a single set as an adult. You press one brick down onto another, feel it click, and it holds. You likely never o

Your birthday tells you how many years you've been alive. But it doesn't necessarily tell you how your body is aging. Two people can be the same age and still have very different levels of cardiovascu

Malware used to be simple to describe. A virus attached itself to a file, and antivirus software removed it. That world is gone. Today, a single attack can steal your passwords, lock up your photos, w

So you shipped your AI feature and it works in demos. Your team is impressed. Then a user asks a question slightly outside your test cases and the model confidently returns something completely wrong.

Every other AI product you open today has the same screen: a message list, a text box at the bottom, and words that stream in one token at a time. It looks simple, but it's not simple to build well. Y

OpenAI Codex is a very helpful tool in modern software development, but getting real value from it comes down to understanding how it is actually meant to be used. To help developers master its core c
