Rust Jobs

I’m leading the MVP development of a space-themed, cross-platform metaverse where players can truly own ships, stations and resources through a token-driven economy. The immediate priority is bullet-proof blockchain integration on Polkadot, and that starts with well-architected smart contracts. I’m looking for a developer based in the US or Europe who can design, code and test the ink! smart contracts that will: • Mint, transfer and burn our space-based NFTs • Handle the in-game utility token (staking, rewards, fees) • Enforce marketplace trades and royalty logic • Plug cleanly into our existing Substrate back-end and Unity front-end Deliverables 1. Production-ready ink! contracts, optimised for weight and security 2. Comprehensive unit + integr...

I need a small Windows utility that sits in the background and accepts a call from a web page running in Chrome or Edge, then forwards the data straight to an Epson thermal printer without showing any OS dialogs. The page will generate a Point-of-Sale receipt; the bridge’s job is to take that payload—whether it arrives as raw ESC/POS, a small PDF, or plain text—and push it to the default thermal printer instantly. Core flow I have in mind 1. My JavaScript calls a local HTTP/WS endpoint (or custom URI scheme—open to what you feel is safest). 2. Your service receives the request, maps it to the selected Epson printer, and fires the job silently. 3. A minimal response (success / error) is returned so the browser app can acknowledge the print. Key expectations ...

Ich möchte eine schlanke Linux-Anwendung mit Libadwaita-Oberfläche entwickeln lassen, die Fotos stapelweise anhand ihrer Exif-Information Datum und Uhrzeit umbenennt. Mein Umfeld: Gnome, GTK4 und die neue Libadwaita-Designsprache. Zielplattform ist ausschließlich Linux (Flatpak-Bereitstellung wäre ein Plus). Funktionsumfang • Grafische Benutzeroberfläche: modern, responsive, hell/dunkel automatisch. • Drag-and-drop oder Dateiauswahl für ganze Ordner und einzelne Dateien. • Exif-Auslese ausschließlich für Datum und Uhrzeit; daraus soll der neue Dateiname nach frei wählbarem Muster entstehen (z. B. ). • Kollisionserkennung mit Zähler oder Benutzerabfrage. • Fortschrittsanzeige und Protokoll am Ende des ...

I need a deeply technical article that walks expert developers through the current best practices for implementing hooks—whether they are API hooks, function detours, middleware hooks, or event-driven listeners. The piece should assume the reader is already comfortable with low-level concepts, so please focus on the nuances that separate a solid implementation from a fragile one. What I expect • Length: roughly 2,500–3,000 words, written in clear, concise English. • Depth: cite real-world examples, contrast alternative strategies, and highlight edge-case pitfalls that only surface in production. • Code: provide self-contained snippets (C/C++, Rust, and optionally JavaScript for browser hooks) that compile or run as-is, accompanied by short explanations of wh...
