I’m running Base44 on a Plesk-hosted VPS and want every embroidery file a user uploads to instantly generate a PNG preview that shows up right inside the app. The obvious path seems to be wiring Embroidermodder (libembroidery command-line tools) into the server, but I’m open to any cleaner or lighter-weight method you might propose—as long as it’s fully automated and stable. Scope of what must work – Accepted upload formats: DST, PES and EXP. – As soon as an upload completes, a server-side routine should convert it to a PNG. – The resulting PNG is stored and immediately rendered back to the user in the existing “view” area of Base44 (no download links or e-mails; the preview lives in the app UI). – Solution must fit smoot...

Quiero un script en Python que revise en tiempo real todas las acciones disponibles en Revolut y me envíe una alerta por Telegram cuando detecte una subida inminente del 5 % dentro de un intervalo de 5 min. Requisitos clave • Cobertura: el monitor debe abarcar todas las acciones listadas en la plataforma, sin exclusiones. • Frecuencia: chequeo continuo o, como máximo, con una latencia de segundos; no quiero perder ningún movimiento rápido. • Precisión muy alta: la lógica de cálculo debe minimizar falsos positivos y entregar la alerta solo cuando el diferencial de precio represente realmente un +5 % en menos de 5 min. • Notificación: el aviso debe entrar por Telegram (puedes usar bots de la API oficial). ...

Deseo contar con un servidor de correo Carbonio Community funcionando sobre Ubuntu. El VPS ya está provisionado con una instalación limpia de Linux; tu misión es: • Instalar la última versión estable de Carbonio Community, dejarla operativa con los servicios necesarios (webmail, calendarios, contactos, ActiveSync si corresponde) y crear un dominio de prueba para verificar el envío y la recepción. • Aplicar una configuración básica —puertos, certificados TLS, ajustes de DNS como SPF, DKIM y DMARC— para que el correo se entregue sin problemas de reputación. • Endurecer la instalación con foco específico en la seguridad del servidor de correo: reglas de firewall acordes, protecci&...

I need a tailored set of Cloudflare WAF rules that operates as a Custom Bot Policy. The objective is straightforward: detect suspicious, automated traffic and have Cloudflare respond with a CAPTCHA challenge instead of an outright block. You’ll start by assessing my current Cloudflare configuration, then craft one or more custom WAF expressions that reliably flag bots through indicators such as abnormal request rates, header irregularities, IP reputation scores, or other signals you’ve had success with. Once matched, the rule action must be “Challenge (CAPTCHA).” Deliverables • Finalised WAF rule set added to my Cloudflare dashboard • Proof-of-concept tests showing legitimate users unaffected and bots challenged • A brief hand-over note ex...

I’m spinning up a fresh Ubuntu VPS and need it turned into a rock-solid hub for my IoT fleet. The box must host two main services—Mosquitto for messaging and a Mender server for over-the-air firmware updates—without compromising security, performance, or future maintainability. Here’s the picture • Mosquitto will run behind TLS with mutual authentication. I’ll give you the root CA; you generate and stage broker and client certs so the standard mosquitto_pub / mosquitto_sub TLS test passes. • Mender must be installed in its open-source edition, set to distribute only signed artifacts. I already sign firmware; the server simply has to enforce signature checking before rollout. • fail2ban on the host should block any source IP after three ba...

My provider has suspended my Ubuntu VPS after flagging a hack on the web-server layer (Apache/Nginx, exact stack is in the incident report I will share once we start). At the moment I have zero hardening in place—no firewall rules, no SSL, nothing—so the attacker clearly found an easy way in. I do have a recent full backup, so you can work safely and roll back if needed. Your mission is to identify the entry point, remove any malicious code or files, close the vulnerability, and leave the server in a state that convinces the host to lift the ban. You are welcome to use tools such as fail2ban, UFW/iptables, ClamAV, rkhunter, ModSecurity, or any other utilities you normally rely on. Deliverables • Clean, uncompromised web root and services reinstated • Detailed ...

I’m running a Debian server and need the system language switched from its current setting to Ko-kr. Your task is to: • Reconfigure the server’s locale so all system messages, man pages, and default environment variables use Ko-kr. • Verify the change persists after a reboot and is applied for both root and regular SSH sessions. • Provide a brief set of commands or a script so I can repeat the process on future servers if needed. Please work directly on Debian, avoid disrupting running services, and share a short confirmation (e.g., output of locale and localectl) once the change is complete.

Quiero implementar en mi servidor Linux un sistema OMR escrito en Python que me permita elaborar, procesar y calificar hojas de respuesta de 1 a 100 preguntas. Necesito que desde la propia interfaz gráfica pueda: • Diseñar plantillas personalizadas: definir número de preguntas, incluir nombre de la institución y cargar el logo. • Reservar cuatro columnas de dígitos (0-9) que el alumno sombreará para generar su código interno; por ejemplo, 1101 identificará “PRIMERO A – Estudiante 01”. • Escanear la hoja PDF o imagen, identificar automáticamente al estudiante mediante esas columnas y leer cada burbuja para asignar la nota. • Guardar los resultados directamente en MySQL y permitirme co...

Description I’m hiring an experienced Open Tibia developer to deploy a modern 13+/14.12 stack using Canary (OTBR) and deliver a complete working foundation: server + client + website accounts, with proper backups and rollback. This is an assets-based 13+/14+ project (not 8.6 / legacy). 1) Server (Ubuntu 22.04 VPS) Install/configure Canary (OTBR 14.12+) MariaDB setup Proper config + ports + firewall systemd services with auto-restart Confirm clean restarts and stability Start with a standard map base (I’ll move to a custom map later) 2) Client (Windows) Compile OTClient Redemption (Windows) Preconfigured connection (no IP editing) Basic branding (name/logo) Package as downloadable ZIP Auto-update setup for client files/modules/assets (versioned) 3) Website (AAC) ...

I have already created the subdomain of my main domain where will live and I can give you full SSH/root access to the Linux server that powers it (Ubuntu 24.04 with HestiaCP panel running on port 8083 of main domain). Subdomain has ssl via Let's encrypt. All I need is a clean, production-ready installation of the latest stable release, configured so it loads flawlessly from the subdomain (HTTPS, reverse proxy, environment variables, database, etc.). I have a VPS hosted by Hostinger. You are free to use the official Docker set-up or a manual Node.js build—whichever you feel is most reliable—but please secure it properly, connect it to a Postgres database (which has to be setup as well), and leave me with concise notes so I can maintain or upgrade it later. Acceptance wi...

I have a fresh Ubuntu 22.04 VPS ready and I want a fully working Open Tibia server running version 13.x or newer. I am happy to go with either Canary or TFS—whichever you feel will get us to a stable, live server fastest. My own attempts stalled mainly at the client-connection stage, so the critical piece for me is having at least one client (official Tibia or OTClient, I am flexible) connect reliably to the server once it is online. What I need from you: • Compile or install the chosen engine on the VPS, configure it, and verify it boots without errors. • Walk me through the minimal config changes so I understand what was done. • Provide a working client package—or clear instructions for obtaining and patching one—that logs straight into the serve...

Necesito implementar encriptación de datos en un servidor Linux para proteger exclusivamente archivos y documentos. Mi objetivo es contar con una solución sencilla y funcional que deje los ficheros cifrados en reposo sin complicar el resto del sistema.

The immediate goal is to bring fully-functioning validator and miner nodes for both Gonka AI and Bittensor online, running on rented H100 GPU servers. I already have the hardware allocated and wallets ready; what I need is an engineer who can take the nodes from zero to profitable operation and then keep them humming. Key tasks • Provision and secure each H100 instance, configure networking, firewalls, SSH keys and wallets • Containerise the stacks with Docker (Kubernetes or Podman are possible later, but Docker is fine for the first iteration) • Tune CUDA-level settings so every GPU cycle counts and rewards are maximised • Build simple Bash or Python scripts that monitor logs, restart on failure and push basic alerts • Produce step-by-step documentation...

I’m running Ubuntu Server 22.04 on a Hostinger VPS and need a clean, dependable way to spin up Cal.com. Docker is not installed yet, so the first step is to get the latest Docker Engine and Docker Compose up and running with their default settings. Once Docker is active, I’d like you to: • Pull the official image (or build from source if that is the current best practice). • Launch the container so it auto-restarts and survives server reboots. • Expose the required ports and, if it simplifies access, wire it to an Nginx reverse proxy so the calendar sits behind my existing domain or a sub-domain. • Hand over the exact commands, configuration files, and environment variables you used, commented clearly so I can reproduce or tweak them later. I&rsquo...

We are looking for an experienced DevOps / GitLab CI engineer to design and implement a robust CI/CD setup for a Docker-based application consisting of a backend and a frontend, both living in the same GitLab repository. The goal of this project is to establish a clean, developer-friendly workflow that supports: Automatic internal test deployments (review apps) for feature branches Automated production deployments to a public VPS when code is merged to main This setup should follow GitLab CI best practices, especially GitLab Environments and Review Apps, and be simple for developers to use without requiring manual server access

I need a proven Airtel Black SIP configuration running on my Ubuntu machine and handled through Linphone. The goal is a clean, documented initial setup—no trial-and-error learning on my system, please. If you have already registered an Airtel SIP trunk on Linux, you’ll know the exact registrar format, the unusual port mapping Airtel uses, and the little tweaks that keep audio flowing both ways behind NAT. Here’s the workflow I’m expecting: • Install or verify the latest Linphone and any required dependencies on my Ubuntu box. • Register the Airtel Black SIP account, applying the correct proxy, authentication string, and codec priorities. • Prove the setup with at least one inbound and one outbound call (I can join you on a test call). •...

I have completed a desktop application with Lovble IA and pushed the code to a GitHub repository. Now I need it running smoothly on my own Linux server. Your job is to pull the repo, set up whatever build or runtime environment Lovble IA requires, resolve any package or dependency issues, and make sure the executable starts up reliably (ideally as a service so it can restart after reboots). The repository is ready for cloning; you will receive access as soon as we start. I expect the finished application to launch without errors from the server’s command line or through an appropriate display manager, and I’d like brief notes on every step you take so I can replicate or update the deployment later. Deliverables • Working installation of the Lovble IA desktop app on my Li...

I’m putting together a new Raspberry Pi build that will run Ubuntu rather than the standard Raspberry Pi OS. My own experience level is advanced, but I’d like another seasoned set of eyes to speed things up and help polish the system. The job focuses on: • Reviewing my current headless Ubuntu image for best-practice partitioning, bootloader tweaks, and basic hardening • Tracking down and fixing the boot-time warnings that surface in dmesg and journalctl • Suggesting and, where sensible, applying performance optimisations—overclock settings, thermal management, swap behaviour, I/O tweaks • Writing or refining a few clean Bash/Python scripts for unattended updates and off-device backups We’ll work entirely over SSH, so no hardware shipping...

Our in-house desktop application for Linux has started throwing an error that disrupts a critical workflow. I already have the full source code and a reproducible test case; what I now need is a clean, well-documented bug-fix patch that eliminates the issue without introducing regressions. Here is how I see the collaboration: • You clone the repo (Git) and replicate the bug on any mainstream Linux distro. • Diagnose the root cause, write the fix, and submit it as a unified diff/patch file plus the updated build. • Prove the fix with the supplied test case and a brief regression checklist so I can validate it quickly on my side. • Keep comments concise and follow the existing coding style; no sweeping refactors—just the focused bug fix. Once I verify that ...
