Here's a pattern almost every product with invoicing eventually hits: revenue is up, the growth chart looks fantastic, and yet the bank balance is oddly thin. The founder asks, "Where's the money?" and somebody opens a…
Notifio is a £20 one-time purchase. Not £20 in the UK and something else elsewhere: every Checkout Session is created in GBP pence, the webhook records GBP, the licence is GBP. There is exactly one currency in this…
Every monorepo tool eventually describes itself with a paragraph of nouns: caching, task graph, remote execution, affected detection, generators, a dashboard, a cloud. vx's description is one sentence. vx runs and…
vx runs and caches a task graph, correctly, and stops there. It is a task runner and a content-addressed cache for JavaScript monorepos, built on Bun, with nothing hidden behind a paid cloud. One run, then the same run…
If you've ever shipped an invoicing feature, a wallet, a marketplace payout flow, or even a "simple" subscription billing page, you've written code that touches money. And if you've written code that touches money,…
Why DXF Is Not Just a 'Text Version of DWG': Floating-Point Roundoff and Entity Drops Engineers often assume that saving a CAD model as DXF (Drawing Interchange Format) is simply exporting an ASCII equivalent of native…
If you're beginning your journey into web development, you've probably encountered two words almost immediately: HTML and CSS. You may have seen developers writing HTML elements, CSS rules, classes, selectors,…
Declarative vs Imperative Animation in React: Where Each Model Wins A menu opens because isOpen became true. A notification leaves because React removed it from the tree. A card changes visual state when it receives…
A user types «احمد» (Ahmad) into your search box and gets nothing, even though the page says «أحمد». Or they search for «مدرسه» (school) and the text has «مدرسة». Or they search «محمد» and the text is vowelled,…
AI disclosure: This tutorial and its sample code were prepared with AI assistance. It is a local implementation recipe, not a device-performance benchmark. A rarity reveal should draw attention to an item without moving…
TL;DR A push ticket that says "ok" only means Expo accepted your message. Whether Apple or Google accepted it is in the receipt, which you have to fetch yourself ~15 minutes later. Expo Go can't do remote push on…
I run two letter sites. Digital Letter, where you pick a design, write a note, seal it in a digital envelope, and send it with a link. And Open When Letters, where you write letters ahead of time, each one sealed until…
arXiv:2610.10787v1 Announce Type: cross Abstract: Language models trained with long-horizon agentic reinforcement learning can generalize knowledge through reasoning, express precise actions, and pursue goals over many…
arXiv:2610.12007v1 Announce Type: cross Abstract: Flow-based vision-language-action (VLA) models generate action chunks for temporally coherent robot motion, but chunked control creates a fundamental closed-loop…
O que é o DOM e o que o React realmente faz com ele? Este é o primeiro artigo de uma série que quero escrever: “Coisas que usamos todos os dias, mas raramente paramos para entender.” A ideia é escolher conceitos que…
Group decisions are where friendships go to stall. "Where do we eat?" "Who goes first?" "Who does the dishes?" — everyone has a preference, nobody wants to be the decider. So I built a small spinning wheel that takes…
We build ClearPix, a set of media cleanup tools that run entirely in the browser — no uploads, no server GPUs. That means when a user removes a watermark, a 198MB LaMa inpainting model runs inside their tab, and when…

Background jobs are essential when a Node.js application needs to perform work without making the user wait for the result. Sending emails, processing reports, resizing images, generating invoices, syncing external…
Since 1 January 2025 every business in Germany must be able to receive structured e-invoices, and since 1 September 2026 so must every VAT-registered business in France. The trouble is what arrives: an XML file…
