    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...

    I need a developer to create a dedicated communication-management tool that runs natively on Linux. The core requirement is the ability to establish, track, and gracefully close sessions over both TCP/IP and UDP. All connection handling, queueing, and basic error management should happen inside the tool so that client applications can speak through a clean, well-documented API instead of implementing their own socket logic. This tool must be system centric installed on our Linux server Here is what I have in mind: • Command-line operation is fine for the first iteration, but please structure the code so a lightweight GUI or web dashboard could be bolted on later. • Clear logging of connection events, dropped packets, and throughput statistics is essential—I’ll be p...

    Ich betreibe einen Linux-Server unter SLES 15, hinter dem bereits ein Loadbalancer vorgeschaltet ist. Für diesen Server möchte ich eine saubere Apache-Konfiguration, die den Traffic korrekt vom Loadbalancer übernimmt und anschließend zuverlässig an die gehosteten Anwendungen weiterleitet. Dein Auftrag umfasst: • Installation / Prüfung aller benötigten Apache-Pakete auf SLES 15 • Erstellung einer übersichtlichen inklusive aller benötigten Module • Einbindung der vorhandenen Loadbalancer-Header (X-Forwarded-For usw.), damit Logs und SSL-Terminations richtig ausgewertet werden können • Absicherung des Setups (Hardening, sinnvolle Defaults, Firewall-Checks) • Dokumentation jedes Schritts, sodass ich Ä...

    X-ray Image Type Classifier

    Cont confirmat

    I have a collection of X-ray studies and I need a robust deep-learning model that can look at each image and instantly tell me which predefined category it belongs to (e.g., chest PA vs. chest lateral, cervical spine, hand, etc.). The job is strictly about classifying the type of X-ray, not diagnosing any pathology. Here is what I already have and what I expect from you: • A curated folder structure with several thousand labelled PNG and DICOM files that you can download from my secure server. • A preference for Python with either PyTorch or TensorFlow/Keras—use whichever framework you feel will achieve the best accuracy and fastest inference on a modern GPU. • Clean, reproducible code (Jupyter notebook or script) plus a short README that explains environment se...

    Open Source Linux Fax Server

    Cont confirmat

    I need an open-source fax solution deployed on a Linux host so I can both send and receive faxes from the network. Every incoming fax must be archived automatically as a PDF, and all administration—including queue monitoring, user setup, and log review—has to be handled through a clean, browser-based interface. Any stack that meets those points is fine Like ICTFax as long as it runs on a recent Debian/Ubuntu or CentOS release with no licensing fees. I will supply SSH access to a fresh VM and either a Class 1/2 USB modem or a T.38 SIP trunk you can register against. Fax server installation & system hardening SIP trunk / FoIP gateway integration Incoming & outgoing fax routing and testing Web-based fax send, receive & management Automatic PDF conversion for all...

    MANUS.IM HostGator Migration & Setup

    Cont confirmat

    I want the entire site moved to my HostGator account and running exactly as it does now. The project is built on Node, so you will need to install and configure the correct Node version over SSH, copy the current codebase, restore all environment variables, and make sure every existing API integration is fully operational after the move. You will have SSH access to the new server as soon as we start. Once inside, you can choose the quickest route—npm, yarn, PM2, Git pull, or any workflow you prefer—as long as the final result is a clean, reproducible deployment that survives a reboot and can be updated easily in the future. Deliverables • Node environment installed and verified on HostGator • Complete site migrated, including assets and database (if applicable)...
