Can Copilot Fix Its Own Security Findings? Testing GitHub Agentic Autofix

Can Copilot Fix Its Own Security Findings? Testing GitHub Agentic Autofix GitHub can now assign a code scanning alert directly to Copilot cloud agent. The agent explores the repository, changes code, attempts validation, and opens a draft pull request. That is more ambitious than generating a patch beside one vulnerable line. It is also not the same as proving that a vulnerability is go...

From CPU Legacy Code to GPU Performance: Porting a 500K-Line CFD Solver

We recently ported our 500,000-line in-house CFD solver to AMD GPUs. A naive GPU port already achieved a 9.5× speedup. After redesigning the data layout and systematically removing bottlenecks, we reached 37.8× speedup. This article explains the engineering decisions that mattered in this journey.IntroductionPorting a mature production code to GPUs is rarely as simple as replacing a few loops with...

What breaks if I delete this file? React tooling can't answer that.
DEV Community • 2026-08-17 14:20

What breaks if I delete this file? React tooling can't answer that.

You want to delete a file. A quick search shows three direct imports. That's easy enough to see. The harder question is what those three files are used by. One may be a layout dependency. Another may be part of navigation. A third may feed a page that doesn't look related at first glance. So the real question isn't "Who imports this file?" It's "What breaks if I remove it?" Most tools don't ...

Why I Built a Browser-Only Tool Platform (and What Broke That Rule)

Every "free online tool" site has the same shape: pick a task — resize an image, merge a PDF, decode a JWT — upload a file, wait, download the result. That upload almost never needs to happen. Browsers have had the APIs to do this work locally for years. The upload step exists because it's the easiest way to build the product, not because the task requires a server. That's the premise behind Tabr...

🚀 This Week's Build: Save. Share. Stay Aligned.

New week, new ship. This week our team is taking a dashboard-sharing feature from idea to production — and I wanted to share the plan in case it's useful for anyone else structuring a feature sprint. The goal is simple: let users save a dashboard view and share it with teammates in just a few clicks, with proper permission controls (Viewer / Editor) baked in from day one. Here's how the week bre...

Don't Give the Model SQL

I built a web app to answer questions about my own health data, for a reason that is embarrassingly small. I already had a perfectly good way to ask them: a Claude Code skill that queried the database and reasoned over the results. It worked well. It also can't run on Claude iOS, and the moment I actually want to ask "should I be worried about this" is standing in a kitchen at 6am, not sitting at ...

Every Number I Didn't Measure Was Wrong

I went to publish something about the database behind my personal health tracker, and fact-checking it took a day. By the end, most of the numbers I had written down to justify that database's design had turned out to be wrong. Not wildly wrong. Wrong in the quiet way, where the conclusion still holds and the reasoning under it has rotted. Every single one had the same cause: I measured something...

The Past Keeps Changing

I moved my personal health tracker onto a time-series database this month. It holds 69,000 rows in thirty megabytes. That is not a defensible reason to use one, and I want to be blunt about it before you get there on your own. Nothing I did made anything faster and nothing needed to. What it replaced was smaller still. An 840 KB SQLite file on my laptop, seventeen metrics, about 280 health obser...

The Job AI Can’t Apply For

There’s a question we engineers keep dancing around instead of answering directly:If AI can write most of the code, why do we still need engineers?The usual answers I’ve received so far, “engineers make decisions” , “humans are creative” and “AI is just a tool” are too vague to mean anything. Let’s take the question seriously instead.Say I hand an AI a well-defined requirement and it produces the ...
