The UK MET office recently redesigned their site, adding a lot of additional whitespace, scrolling, and animations. This significantly reduced its usability for me, and left me wanting an ‘at a glance’ weather site. I made https://brolly.sh , a minimalist, plain text weather forecasting site. You can use it to view weather from around the world, with: 7 day forecast; Previous day log (so you can confirm it definitely was cooler / hotter / wetter / drier yesterday!); Hourly rain, wind, temperatu...

Hi, friends! Welcome to Installer No. 137, your guide to the best and Verge-iest stuff in the world. (If you're new here, welcome, happy phone season, and also you can read all the old editions at the Installer homepage.) This week, I've been reading about Google Zero and armored cars for rich people, watching a […]

What Surrounds Us takes its title literally. You play as a circle surrounding a hole in its middle - it looks like a donut with frosting. You work together with other sentient moving circles, sometimes helping them joyfully meet with others. And you traverse a large map that's composed entirely of, you guessed it, a […]

Is an e-reader case as dangerous as a Glock 19? Last month, Louisville, Kentucky-based creator Luke The Maker showed off a bizarre, 3D-printed, pistol-shaped case design for the popular minimalist Xteink X4 e-reader. The X4 lies vertically atop the plastic gun's slide, with a cutout on the side to access its buttons. Though the frame […]

Warner Bros. Discovery has filed suit against Amazon, accusing it of illegally poaching employees, including Pia Barlow, former senior VP for originals marketing. In the complaint, Warner says that "Amazon has chosen to ride on the coattails of other well-established Hollywood mainstays," and that it engaged in a "lawless employee shopping spree." Deadline reports that […]

With elements from synthesizers, loopers, and effects pedals, Teenage Engineering’s devices lie somewhere between musical instrument and modern art. These grooveboxes, as they’re often called, are capable of helping you produce songs in real time from a single unit, with an eye-catching design language. A wide swath of the brand’s offerings are 30 percent off […]

Oli Freke is a musician and journalist whose works have appeared in Sound on Sound, The Quietus, and Mixmag. This has included using math to explore the melodic potential of the Western 12-tone scale and deep dives on effects plug-ins. He's even written a book tracing the evolution of the synthesizer from 1963 through 1995, […]

A close call in Northern Virginia revealed just how poorly data centers respond to grid disruptions. Here's how to fix the problem.

At libraries around the country, "Avoiding AI" workshops have elicited unprecedented demand.

Getting an app to work has stopped being the hard part. You describe what you want, Lovable or Bolt or v0 builds it, and forty minutes later there's something on a real URL that real people can click. The hard part moved. It's now everything between "it works" and "it survives contact with the internet." That gap isn't a vibe. It's measurable. Symbiotic Security crawled 65,643 URLs and fully scanned 1,072 Supabase-backed vibe-coded apps in June 2026: 98% had at least one security issue...

Most ad-hoc timing code in Python looks like this: start = time . perf_counter () result = do_work () elapsed = time . perf_counter () - start stats [ name ]. append ( elapsed ) It works, until do_work() raises. Then the line that records the timing never runs, the exception propagates, and the one call that was probably slowest — the one that failed — is silently missing from your stats. If you're using timing data to find what's expensi...

int(os.environ.get("PORT", "8080")) fails constantly in ways that waste your time: ValueError: invalid literal for int() with base 10: 'abc' . No variable name. No hint about what a valid value looks like. You grep the codebase for PORT to even find where the read happened. specenv is a zero-runtime-dependency Python library for typed environment variable loading — casting, validation, schema grouping, prefix namespacing. All of that is useful, but none of it is the actual design decisi...

Most "save this for later" tools I've used eventually want a server: an account system, a database for your notes, a sync service with its own outage history. I wanted something narrower — capture text or a whole page while browsing, turn it into a spaced-repetition flashcard, and have it show up on my other machine — without running any infrastructure at all. MindStack is a Manifest V3 Chrome extension that does exactly that: capture, spaced-repetition scheduling, a full dashboard, and cro...

Every party game app I'd used before building this one wanted an account, a lobby website, or a subscription. I wanted the opposite: plug a laptop into the TV, run one command, and have everyone's phone connected in under thirty seconds — no internet required once the LAN is up. That constraint ends up dictating almost every architectural decision in GameNight : a Node/Express/Socket.io server that runs five real-time party games — a Mafia-style social deduction game I call Mongolpuri, UNO, ...

Run two AI coding agents on the same repo and the first thing that breaks is not the code. It is coordination. Agent A starts refactoring auth. Agent B, running in parallel, has no idea and starts the same thing. Neither remembers what it did last session, because each one boots fresh with an empty context window. The usual fixes are worse than the problem: a state file in the repo pollutes every diff and conflicts on merge, and an external issue tracker means API tokens, rate limits, and ...

A coding agent can produce a confident patch for the wrong problem when the input is only: The upload sometimes fails. Please fix it. That sentence does not identify the smallest failing input, exact error, environment, expected result, frequency, or even whether the reporter reproduced it personally. If the first instruction is “fix it”, the agent has room to turn a suspected cause into a fictional fact. The safer sequence is: preserve the observed failure; record the real e...

In 2017 the National Archives and Records Administration (NARA) released the JFK files in an unsearchable manner 🔍. I tried doing manual research 🕵🏻. I relied on their provided CSV file of metadata to look for relevant documents to discover something - but I was looking for a needle in the haystack. I didn't know where to begin - but at the very least, I wanted to be able to search the contents therein. At least the National Archives allowed me to bulk download the PDFs. From that, I was able to...

An MCP server is a small app that extends an AI model's capabilities by giving it access to custom tools, a particular set of data or workflows. It's based on the Model Context Protocol, which is an open standard for connecting AI apps with these external sources. The most straightforward way to create an MCP server is to use the official SDK, implement a single function and mark it as a tool and then expose it through stdio (standard input/output) which you can register in Claude Code; it ba...

I created Agent-Up , an open-source desktop app and local server for running multiple coding-agent environments on one machine. Worktrees isolate source code, not the runtime The problem is that Git worktrees isolate source code, but they do not isolate the running application. When several agents work on the same monorepo, each one may need its own: application processes, ports, Docker services, logs, runtime state. Without a shared runtime manager, agents ...

A test failure that takes 20 minutes to surface, buries the error in 3000 lines of log output, and gives no context about what changed is nearly useless. Good test reporting transforms raw pass/fail data into actionable signals. Failing fast — stopping the pipeline the moment you have enough information to make a decision — keeps feedback loops tight and respects developer time. These two concerns are deeply connected: you can only fail fast confidently when your reporting is good enough that...

This is a submission for DEV's Summer Bug Smash: Smash Stories powered by Sentry . "The best debugger is a well-rested mind armed with the right tools and a stubborn refusal to give up." The Call to Adventure It started like any other day. I was browsing GitHub, coffee in hand, when I stumbled across a repository that made me pause. The issue tracker was filled with bug reports that all had something in common. They were being ignored. Not because the maintaine...
