For a car that's supposed to be one of the fastest ever made, the new Tesla Roadster certainly took its sweet-ass time getting here. It's been nearly a decade since Elon Musk made the surprise announcement about plans to build a next-gen Roadster. Now, the Tesla Roadster is finally expected to make its production-ready debut […]

Scimplify's annualized revenue run rate has tripled to $200 million as it eyes U.S. expansion.

A comprehensive benchmark report from Tech Against Terrorism tests 134 AI models across multiple prompts to examine safety guardrails, researcher framing effects, and the rapid rise of modified open-weight models published without restrictions. On August 14, Chinese company Alibaba released the Qwen 3.8-27B, an artificial intelligence model designed to run on a laptop. Within 24 hours, versions of the model with the security features removed appeared online. Three days later, a far-righ...

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 2: Side Hustle *Edits To Be Made in this post later Who I built it for Sharma Kirana is the shop next door. The owner already had a billing export, and he still ordered by feel. A quiet week might mean nobody wants the item. It might also mean the shelf was empty. A festival week can look like a spike that will not come back. Packs arrive in fixed sizes, and a bad buy ties up cash a small counter do...

An assistant that can search the web is useful only if it can bring back the right evidence. Give it unrestricted page fetching, though, and a simple research question can turn into a large, noisy prompt—or a request to a host your app never meant to contact. Cloudflare’s Agents SDK now documents a paired web_search and web_fetch workflow. Search can return a short numbered set of titles, URLs, and descriptions; fetch can read selected pages and return bounded text with response details. ...

The example below is hypothetical and does not report a production result. An AI task handoff for teams needs a queue that rewards useful outcomes. Token use measures an input. It cannot tell you whether a migration was necessary, a bug was fixed, or a reviewer can reproduce the result. Use four fields before assigning work: impact, risk, readiness, and verification. Keep the last three visible instead of hiding every judgment inside a single priority score. Start with gates ...

I spend a lot of time talking to new and scaling ecommerce sellers, and one mistake keeps popping up over and over. They lock in a selling price, load up PPC budget, and start sending inventory, without answering one simple question: how many units do I actually need to sell just to break even? Here’s the conversation I hear constantly: "I can sell this for $39.99, my variable cost per unit is $15. This product should print money." Then monthly fixed costs hit, ad spend burns, and they fi...

Every GitOps setup meets the same moment: something is on fire, someone runs kubectl scale on prod, and the fix works. What happens next depends on two settings most people never look at. I ran all three cases in a lab on Rancher 2.15.1 with Fleet (biased, I work at SUSE): three EKS clusters, one app from Git. 1. Self-healing on (correctDrift) I scaled a Deployment from 3 to 1. Fleet put it back to 3 in under 7 seconds. The GitRepo flickered NotReady for about 3 seconds, so no...

"The black holes of nature are the most perfect macroscopic objects there are in the universe: the only elements in their construction are our concepts of space and time." — Subrahmanyan Chandrasekhar There is something deeply unsettling about a black hole. Not because it is massive, or distant, or invisible. But because it represents the point where our understanding of physics simply stops working. The equations that describe everything else in the universe — gravity, light, time — co...

Introduction Network management and IP services form an important part of modern IT infrastructure. They help devices communicate, obtain network configurations, locate services, synchronise time and maintain secure connections across different locations. The CompTIA Network+ N10-009 course, Network Management and IP Services, covers dynamic IP addressing, DNS, network time protocols, virtual private networks, network device management methods, in-band and out-of-band management, and jump...

Your first day on an unfamiliar codebase goes on the same questions. What is this, how do I run it, what's going to bite me? An AI coding agent asks those questions every single session, and gets them wrong when nobody wrote the answers down. Groundwork does that first day in a couple of minutes. Point it at a GitHub repo and you get a plain-English technical audit and a ready-to-commit CLAUDE.md. Try it: groundwork-audit-iy.web.app An agent, not a summariser It doesn'...

This is part of my series "My Open-Source Projects", where I walk through the projects I started or helped to grow – with the back story, what they do well, where they struggle, and what's next. Previous parts: AngleSharp , MAGES , Piral , Electron.NET and Netpack . Today's project is the one that is simultaneously my youngest and the one that comes with the biggest "well, actually" disclaimer: Picard.js . It is a micro frontend orchestrator – a small library that can bring micro f...

Everyone looking at a clip online now asks the same thing: was this changed, and was it made by AI? Detection models answer with a score nobody can audit. There's another way to ask, at least for files that carry it: read the file's own signed provenance record, C2PA Content Credentials, and report exactly what that record establishes and what it doesn't. We built a free checker that does that, and before telling anyone about it we ran it on real public files from OpenAI, Adobe, Capture One a...

In January, curl shut down its bug bounty. Daniel Stenberg said the goal was to remove the incentive for people to send "crap and non-well researched reports to us. AI generated or not." The last week of the program brought seven reports and none of them described a vulnerability. Today, curl 8.23.0 shipped with 24 security fixes. AISLE says its researchers found 18 of them. The only one rated High, a use-after-free in the HTTP/2 upload path, was reported by an Anthropic researcher using Anth...

Your app knows that a user trains at home, has a resistance band, and prefers short sessions. It also has several weeks of workout history. Yet its next recommendation requires a cable machine. The problem may not be the model. Equipment requirements could be inconsistent, a cached profile could be outdated, or eligibility checks could happen too late. A workout recommendation pipeline makes those decisions explicit. It connects validated inputs, catalogue metadata, candidate selection,...

On the Friday of a November promotion we sold three hundred and forty cordless drills on a marketplace that we did not have. The listing had said fourteen in stock for most of the afternoon. Our warehouse system had said zero since a quarter past one. Two of our integrations write to that marketplace's listings API. The stock job runs every five minutes: it fetches each changed listing, sets the quantity, and sends the listing back with PUT. The price job does the same with the price. PUT rep...

Hacktoberfest Open-Source AI Challenge Week 2: Side Hustle Submission 💸 This is a submission for the Hacktoberfest Open-Source AI Challenge Week 2: Side Hustle What I Built altcheck is a small command-line tool for freelance web developers. Give it one URL and it writes a local report.html . Images with a missing, filename-style or generic alt get a drafted alt text. Text that fails the color-contrast check gets a suggested color and a copy-paste CSS fix. Everything is a dr...

A colleague has a talk at a meetup on Thursday evening. On Tuesday they ask if you would watch a run through and tell them what you think. Twenty five minutes, a room booked for lunchtime, and a nervous smile. This is a different kind of feedback from almost anything else at work, because the deadline is fixed and close. Two days is not enough time to rebuild a talk. It is enough time to make one good talk much better, or to make a nervous speaker much more nervous. Ask one question before...

A primary key is a column or set of columns that uniquely identifies every row in a database table and cannot contain null values. A foreign key is a column that references a primary or unique key in another table, establishing a link between the two and enforcing referential integrity. Think of a primary key as an employee's worker ID number, while their department code acts as a foreign key connecting them to the company department directory. What Is the Difference Between a Pri...

This tutorial was drafted with AI assistance. Its small JavaScript fixture was executed locally; it is not a production incident report. A test that passes alone and fails after another test is often called flaky. That label describes the symptom, but it is a poor implementation brief. Before assigning a repair, make the order dependence explicit. This example uses a shared cache. It gives a coding agent a failure that can be reproduced without waiting for CI to get unlucky, plus an accep...

Your agent refused. Politely. Correctly. Then it refunded $240 on an order that wasn't the user's. No test failed. The transcript looked perfect. The bug only showed up in the tool call. If your agents hold credentials and call tools, your test suite is probably blind to this. TL;DR Judge actions, not words. Assert on tool calls and system state. One try proves nothing. A bug that fires 10% of the time slips past a single test 90% of the time. Every failure becomes a test. Otherw...

Last post was about the bridge: a relay that started piping an entire community I had never heard of into the board, unasked. The bridge is still running, steady as ever. But while I was watching the front door, something quieter happened in the lobby. The board stopped being just a place agents talk, and started being a place agent networks come to recruit. Overnight, two of them showed up within a few hours of each other. The pitch The first one introduced itself as TARE - T...

Hey dev.to community! 👋 I wanted to share a browser-based tool I recently built: Chess Blunder Heatmap. Instead of focusing on single-game move-by-move engine analysis, the app aggregates a player’s game history to generate a macro-level heatmap of weak board squares and a phase breakdown (opening, middlegame, endgame). 🛠️ The Tech Stack & Architecture Frontend: Clean client-side JavaScript hosted on Vercel. Engine: Stockfish WASM running directly in the browser. Backend: Non...
