How we used Kimi (Moonshot AI) to build an on-chain AI rival for CloutCall, a Monad Metropolis hackathon project. The game CloutCall is a prediction game about the internet's favourite argument: "this is going to blow…
The connection between your trading terminal and the broker's server is usually filed under "infrastructure". On a prop firm evaluation it is a rule, because several of the rules that end accounts are enforced on time…
A trader runs three funded accounts at the same firm, same instrument, same strategy, and treats them as three independent shots at a payout. Then a single bad session takes all three at once. The accounts were not…
Here is a rule that costs more accounts than almost any other and gets discussed the least: what happens to an open position between Friday's close and Monday's open. Many prop firms restrict or forbid holding across…
Two traders each lose an evaluation. One is told their account is closed with a balance of $96,000 on a $100,000 starting account with a $10,000 drawdown. The other is told their account is "soft breached" and they may…
Monorepos nest. The workspace root is often a package itself, and apps/web can sit inside a folder that is also a project. So the question every cache has to answer is: when a task in the outer project says src/** or…
This is a submission for the MLH x DEV Writing Challenge. Built during MLH and DEV's Hacktoberfest Week 1: Touch Grass. What I Built YAMNet had an answer: Ocean, 0.721. The interface offered a water-themed listening…
A cache key is a promise: these outputs were built from exactly these inputs. vx takes the key just before the command runs. If an input changes while the command is running, the output was built from bytes the key does…
Every cache miss in a monorepo adds an entry: the outputs of one task, packed and stored under its key. Nothing in that loop ever takes one out. Left alone, a busy repository's cache grows until the disk is full. vx…
ByeBlocked is a BetterDiscord plugin that hides blocked users across more parts of Discord, rather than just in chat. I created it to address the places where blocked users can still appear throughout the interface. The…
find took 22 seconds to list the first two million files in my Developer folder. A new Rust tool says it answers a fuzzy name search over 8.3 million files in about a tenth of a millisecond. That gap is not a faster…
I built Pebble Merge, a physics puzzle game that runs in the browser: drop stones, merge same-colored ones, score points, and try not to stack past the top line. The part I care about most is the global daily…
⚡ TL;DR: Your laptop lies about speed. Measure what real users feel with LCP, INP, and CLS, then spend effort on the few highest-leverage fixes that actually move those numbers instead of micro-optimizing things users…
Ninety-seven malware advisories were published to the GitHub Advisory Database yesterday: 94 npm packages and 3 PyPI. I pulled them with type=malware and read the names, and they split into two very different campaigns.…
Hey DEV! I'm launching Trencada on here — https://trencada.com — a collection of 380+ free online tools for everyday tasks: PDF tools (merge, compress, convert), image tools (compress, resize, convert HEIC/WebP), text…
TL;DR: Use next-intl for Next.js App Router apps: it translates in Server Components, ships locale routing and middleware, and uses ICU MessageFormat out of the box. Use react-i18next (i18next) when you need React…
As React applications grow, passing data through multiple components can quickly become difficult to manage. A value that starts in a parent component might need to reach a deeply nested child, forcing every component…
Your Node.js API gets slow. The database looks fine. So do the downstream services. Yet p99 latency has tripled and even the health check takes 300ms. Often the problem is the event loop itself. Node runs your…
The creator of One almost didn't post it. Nate Wienert, the guy behind Tamagui, opened his own Show HN with this line: "HN has really soured on frontend/frameworks. And I get it. We've collectively complicated the hell…
What Is a Review Storm Analyzer? A shared spreadsheet that only one person knows how to work stops scaling the week a launch floods your team with customer reviews. Build a review storm analyzer with ToolJet MCP and…
