    PHP Email Distribution Script
    6 dni left
    Zweryfikowany

    I need a straightforward PHP server-side script that listens to a single group email address on my own custom SMTP server, captures every incoming message, strips out any attachments, and forwards the cleaned message body to each member of the target group. Each group normally contains between 10 and 50 recipients. Core behaviour • The script is triggered the moment mail is delivered to the mailbox (I can set up a pipe or webhook on the server; just tell me which you prefer). • It must read the original headers, preserve the subject line and plain-text / HTML body, remove all attachments, and then send the resulting message to every address stored for that group. • Bounces or failures should be logged to a simple flat file for later review.

    Moodle 4.1→5.1 Migration & Theme

    I need all site settings, user data, and course content moved from my current Moodle 4.1.2 instance into a fresh 5.1.1 installation that is already standing by on a new server. The existing site hosts course materials, quizzes & exams in the form of videos and h5p questions. Beyond the core migration, I also run a Edwiser RemiUI theme with blocks and H5P activities. The theme must be upgraded or refactored to a new fully supported free theme like boost union so it renders flawlessly under Moodle 5.1.1 and will not come with additional costs or software lock-ins. H5P content should continue to play as it does now; if a newer compatible version is required, please handle that in the process.

    Optimize Python Trading Bot
    6 dni left
    Zweryfikowany

    I have a live-trading bot written entirely in Python that connects to the platform through their REST and WebSocket APIs. The strategy logic itself is sound, but under load the bot slows, misses price ticks and occasionally skips orders, so I need a clean performance tune-up and code review. Your task is to comb through the existing modules—order manager, data streamer, and strategy loop—identify the bottlenecks, then fix or refactor as needed so the bot reacts in real time without dropping trades. Expect to work with async I/O, websockets, pandas dataframes and a small SQLite trade log. Deliverables • Refactored, well-commented Python code with any slow sections profiled and optimised • A brief report that explains each change, shows before/after latency b...

    We are seeking an experienced ClawdBot/OpenClaw practitioner who can also handle AWS setup to help stand up a Clawd-based CloudBot environment on Amazon AWS for two users. This is a turn-key engagement for someone who already understands how ClawdBot /OpenClaw works in practice - including setup, security boundaries, and safe configuration. AWS is the infrastructure layer, but CloudBot expertise is the priority. Scope includes: • Deploying OpenClaw (Docker preferred) on a single, cost-efficient AWS instance. • Configuring two user accounts with proper isolation and access control. • Setting up one simple interaction method (web UI or Telegram). • Advising on best practices for light integrations (email/calendar) and what not to overbuild. • A short live walkthrou...

    Linux Desktop App Bug Patch
    4 dni left
    Zweryfikowany

    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 ...

    I already have hosting on Hostinger and now want to spin up Clawdbot, wire it to WhatsApp, and turn it into a real-time productivity assistant. Your job starts with a clean, secure installation of Clawdbot on my Hostinger account. Once it is running, I need the bot authenticated to my WhatsApp Business number so I can message it directly. After the connection is live, please configure the bot to: • Draft notes on demand • Compose professional emails from prompts I’ll send over chat • Organize and store documents—specifically text files, spreadsheets, and presentations—so I can retrieve or update them through simple WhatsApp commands I’ll supply API keys and hosting credentials as soon as we agree on the approach.

    Linux Cloud Telegram Bulk Sender
    4 dni left
    Zweryfikowany

    I’m looking for a small, no-frills tool that I can spin up on a Linux VPS and use to blast out a single message to every recipient listed in a CSV file. The workflow is simple: I upload the CSV, paste or type the message, press send, and watch the log as each username or user_id is processed. Core expectations • Runs headless on common Linux distros (Ubuntu/Debian preferred) • Leverages the unofficial Telegram API • Accepts CSV upload (one column of @usernames or ids) and sends the same text to each entry in sequence • Streams progress to stdout or a minimal web dashboard, then saves a completion report (sent / failed) to CSV or JSON Deliverables 1. Clean, well-commented source code 2. Step-by-step setup notes I can follow on a fresh server (Dockerf...

    We need from Pakistan or India. We need for guidance. • Complete server hardening and best-practice mail stack installation (Postfix or Exim, Dovecot, SpamAssassin, etc.). • Proper DNS records—SPF, DKIM, DMARC, rDNS—set up and verified. • IP and domain warm-up plan to protect sender reputation. • Web-based dashboard or lightweight MTA/ESP front-end that lets me import lists, create campaigns, schedule sends, and view real-time stats. • Step-by-step documentation so I can replicate or maintain the configuration without outside help. If you prefer working with a particular control panel (MailWizz, Interspire, Postal, Mailcow, CPanel/WHM), let me know; I’m flexible as long as deliverability remains the priority.

    I have a working file-transfer script that already handles all the send/receive logic; now I need it wrapped into a polished desktop application that installs cleanly on Windows, Linux and macOS. After installation, the embedded sync-engine must run automatically at regular, short intervals—every few minutes—without user intervention, quietly polling our remote server and pushing or pulling any file changes it detects. What I still need built is the installable package itself along with a lightweight settings interface that supports both light and dark themes. The GUI only has to let users confirm the target folder and, if they wish, pause or resume syncing, so the design can stay minimal yet visually impressive. Under the hood the sync routine should launch on startup (servic...

    I’m in the middle of an ongoing project and have run into a few stubborn issues that I can’t resolve on my own. What I need right now is straight-forward technical support with a strong focus on troubleshooting. The exact fault lines aren’t fully mapped yet—that’s why I’m turning to someone who’s comfortable methodically isolating problems, testing hypotheses, and guiding me to a clean resolution. Here’s how I picture the engagement: • You jump on a quick call or chat to gather environment details and replicate the failure. • We narrow down root causes together—whether the culprit ends up being code, configuration, network quirks, or even a hardware hiccup. • You document each fix or workaround as you go so I can re...

    I need a turnkey deployment of ZoneMinder—or another equally dependable free or low-cost alternative—capable of monitoring dozens of NVRs and cameras distributed across multiple locations. The objective is to have an at-a-glance view confirming that every stream is live, recordings are being written properly, and storage pools remain healthy. Platform selection is flexible; Windows, Linux, or macOS are all acceptable, provided the final environment is stable, secure, and easy to maintain with regular updates. The key requirement is a web-based dashboard that presents real-time device status, allows deep dives into historical performance metrics, and generates fully customizable alerts whenever any parameter moves outside defined thresholds. Instead of integrating with an exte...
