What Browserslist Actually Does in Next.js

We set up three near-identical Next.js 16 projects to answer a simple question: if you set a browserslist target in package.json , does the build change to match it? We tested three targets ( ie 11 , chrome 116 , about 3 years old, and chrome 139 , about 1 year old) and compared the compiled output byte by byte. The code for all three projects is on GitHub: ale-grosselle/nextjs-browserlist-test . The setup All three projects are otherwise identical; here's the source...

Unity_access, major updates and release status

****For the past 2-3 weeks I have been working on Unity_access. For those that do not know, Unity_access is a plugin for the Unity Editor that makes the previously inaccessible Editor more screen reader compatible. In this devlog I will outline the major updates that has happened since the last feature showcase. Updates Accessible Project Window/Assets Viewer One of the main limitations of the Unity Editor is that the Project Window was not accessible. Unity_access n...

Your Agent Keeps Forgetting Because You Keep Switching Models

Three weeks ago, the fastest-growing model on r/LocalLLaMA had no name. The community called it ox-alpha , a stealth release nobody officially claimed. People benchmarked it blind and argued about who built it, then added it to their agent stacks anyway. On August 26 the mask came off: ox-alpha is GLM-5.3-Flash (320B params, 18B active, MIT). That same month, Qwen shipped five releases in 36 days . If you run AI agents, that's a maintenance problem your roadmap didn't budget for. ...

My First Post on Dev Community

I am Muhammad Aoun Khan. I am studying the Computer Science from University of Mianwali. I am learning the full stack development and when I searched the google to find how the backend architecture works then I found the Dev post which explained the concept easily. I hope to contribute to the community and also learn the knowledge and implement it.

Looking for advice on AI-driven development

Greetings! Hope you're all having a marvellous day! I'm looking for some guidance, as I feel like I'm hitting a soft roadblock. I'm not technical, but my work experience comes from working in software development companies for many years. As such, I'm familiar with many development processes, which seems to be helpful. I've spent the last six months learning and slowly building my own app, moving from simple vibecoding to spec-driven development (using Claude Code in VS Code). Howeve...

The Day I Became the One Being pip Installed: My Pre-Release Checks Caught 3 Leaks

(Translation of my Japanese article on Zenn.) This is part 4 of a series where I keep delegating implementation to AI without being able to read the code, building a vulnerability triage CLI called triage-lens. This installment is about distribution rather than the tool's internals: the tool had been sitting on GitHub, and I published it to PyPI so a single pip install triage-lens brings it in. A confession first. Shipping took more nerve than any of the feature work did. And three "lea...

I'm 12. I built a social network for developers. Adults are NOT allowed. (Yes, you. Close the tab.)

My whole life, the internet tells me I'm too young. Too young for a job. Too young for a "serious" platform. Too young to be taken seriously. So I built a place where being young is the entry ticket. DOJO FEED — a social network for developers aged 5–18. Adults get blocked at the door. 🚫 THE BOUNCER When you sign up, we ask your birth year. If you're over 18, you get this: "ADULT DETECTED 🚫 You are 34. DOJO FEED is for developers aged 5–18. Go build your empire on de...

Are We Forgetting Software Engineering in the Race Toward AI/ML?

First of all, I warmly welcome everyone out there in the DEV Community. [Completely open for discussion — drop your thoughts below.] From my perspective, it feels like everyone is racing towards AI/ML. The moment someone says they want to become an AI/ML Engineer, the conversation immediately shifts towards: Python → ML → Deep Learning → LLMs → Latest AI Tools And thinking about it, well, it’s quite understandable too. AI is one of the most exciting areas in technology right now. ...

Hello, DEV! I'm a Game Backend Engineer

I'm a backend engineer mainly working on game servers, with Java as my primary language. Over the years, I've spent a lot of time building and debugging backend systems, and recently I've been digging deeper into concurrency, I/O, logging, and performance. Working on game servers has taught me that many problems look simple at first, but become surprisingly complicated once the system gets busy. I'll be sharing some of the things I've learned from real-world systems, including experimen...

Picking Models as a Mac User

After spending the past two weeks redoing all the models around the house, I realized it might make a good topic to chat about. I know that everyone and their brother has their own way to figure out what models they want to run on their hardware, but I figure that my own criteria might help some of the Mac users out there, so I'm tossing it into the mix as well. Picking which models to even compare When a new model comes out, the first thing I always do is check what folks are sa...

The agent that refuses to guess

I work at a B2B telecom consultancy. I'm not the one auditing the bills, but every month I watch how it's done: open the invoice PDF, check every line against the signed contract, compare it with what the account used in earlier cycles, and write up whatever doesn't add up. It's slow, it doesn't scale, and it's the first task dropped when the month gets busy — which is exactly when the money leaks. And outside a consultancy it's worse: most companies just pay the bill because it arrived....

My Tests Agreed With My Code. Neither of Them Checked Reality

I had twenty-two passing tests and two separate reviewers on a piece of code. None of it objected. Then I pointed it at a real API owned by somebody else and it broke on the first live read. The mismatch fit in one sentence: my parser required ISO 8601, the documented API returned Unix seconds. The repair was not one line. It touched five files, 74 lines of parser and 52 lines of tests. The assumption was small; making it safe was not. Here is why nothing caught it, and it is the part wo...

Flat-fee affiliate tracking without third-party cookies

A merchant running a small programme finds that percentage-based apps charge more as sales grow, while flat-fee tools often rely on third-party cookies that browsers increasingly block. I build ZeroCut. The app charges a fixed monthly fee — Free, $19, or $39 — with 0% commission on tracked sales, enforced server-side. Attribution follows three signals in order: a _zc_ref cart attribute from the theme embed, a real Shopify discount code per affiliate, then the landing_site query param. A 30-d...

What Was the HTML Concept That Took You the Longest to Understand?

When I first started learning HTML, I thought it would be the easiest part of web development. The basic tags seemed straightforward, and creating a simple page didn't take long. But as I kept learning, I realized that HTML is more than just putting elements on a page. Understanding semantic HTML , proper document structure, forms, accessibility, and knowing which element to use in different situations takes practice. For example, it can be tempting to use for almost everything, but lea...

Why AI Agents Fail in Production — and the Guardrails That Fix It

Most AI agent demos work beautifully. Then they hit real users, real data, and real edge cases — and start booking the wrong meetings, leaking context, or looping forever on a task they can't finish. The gap between "impressive demo" and "dependable system" is almost never the model. It's the guardrails around it. This is a practical guide to why agents fail once they leave the demo, and the concrete controls that make them safe to run in production. Why demos lie A demo is ...
