    I have a very small Python snippet that prints “Tumi voter” when age is 18 or more and “Tumi voter na” otherwise. I want this turned into a clean, beginner-friendly example that actually asks the user for their age, validates the input, and then displays the same Bangla messages. The task is deliberately simple: create a single .py file that runs from the command line, requests the user’s age, handles non-numeric input gracefully, and prints the correct message based on the age entered. Keep the code concise, well-commented, and organised so it can be shown to new learners as a model of good practice in Python.

    I need an external utility that runs alongside an online-multiplayer title and quietly automates a few of the repetitive actions players must grind through, freeing us to focus on decision-making and mechanical practice. Because the purpose is to sharpen genuine player skills rather than replace them, the tool should never inject code or tamper with the client itself; it must behave like a lightweight companion app that reads permitted screen or memory data, makes human-like input, and includes solid antiban counter-measures (randomised timings, input variance, optional breaks, and other stealth techniques you normally rely on).

    I run a product stack built entirely on Cosmol 5.5 and need an experienced hand to stay on board for the long haul. Day-to-day work ranges from squeezing every bit of performance out of the current setup, through rolling out brand-new modules, to jumping on unexpected bugs before they disrupt users. Because the platform touches both front-end and back-end layers, a solid grasp of user-facing polish, data-processing logic, and third-party system hooks will serve you well. The codebase lives in Git; regular commits, concise pull-request notes, and clear change logs are non-negotiable. Whenever a feature ships, I’ll expect matching inline comments and a quick markdown brief that explains configuration steps or edge-case behaviour so future maintenance stays painless. Communication happ...

    I’m running a Laravel 10 bulk-media sender that talks to WhatsApp Business Cloud through a webhook. Whenever the API answers with HTTP 429, the webhook does mark the message as failed, yet the queued retry flow (RetryFailedWhatsAppJob on Redis/cloud queue) rarely fires, and when it does, the image-ID matching logic sometimes mis-aligns. The result is missed retries or, worse, duplicate sends. Here’s what needs to happen: • Repair the webhook callback so the media object returned by WhatsApp is always matched to the correct outbound record. • Ensure the job is dispatched, picked up, and processed on the existing Redis-backed queue every time a 429 occurs, honouring the current attempt counter. • Implement a reliable back-off for those 429 responses so we r...

    I’m extending my Bedwars1058 server into a truly competitive arena and need a ranked system coded right away. The core requirements are already mapped out—placement matches, ongoing MMR updates, a /rank lookup, and full data persistence—but the make-or-break piece is fair, dynamic matchmaking. Players must be grouped with opponents of similar rating, with the queue smart enough to widen its tolerance only when wait times get excessive. Everything has to slip neatly into the existing Bedwars1058 ecosystem; no changes to the core game, no clunky commands. Java, Spigot/Paper APIs, and solid MySQL (or equivalent) handling will all be in play.

A successful engagement means you can: • Quickly assess the current state of the task or system you’re handed • Propose and implement practical fixes or improvements • Document what you did so hand-off or future scaling is easy If you thrive in that independent, mid-level sweet spot—strong enough to run with an as...

    I want to turn a Raspberry Pi running CODESYS into a reliable industrial automation node. Your job is to create the complete control application in MATLAB / Simulink using Stateflow, generate the code, import it into CODESYS and prove that it runs in real time on the Pi. The target is an industrial process (details and I/O list come once we start). I need a clean, well-structured Simulink + Stateflow model that covers the sequencing, safety interlocks and regulation logic, then produces compilable CODESYS code without manual patching. Please map the I/O to the Pi’s GPIO or any supported extension modules exactly as documented, and include watchdog handling so the plant fails safe. Deliverables • Simulink/Stateflow model (.slx) • Generated source and export settings ...

    RP2040 Mouse Spoofing Firmware
    5 jours left
    Vérifié

    I need a fully-working firmware for an "Adafruit RP2040 board USB Type-A host" that can sit between a wired gaming mouse and the PC. Its job is to spoof the original mouse’s VID, PID, serial number and any other required descriptor bytes so the operating system believes the orginal mouse is of a different brand. Key behaviour • Gaming mice are the priority, but the solution should fall back gracefully with most common wired models. • All native packets from the mouse must pass straight through untouched, so the user experiences zero latency or feature loss. • At the same time the firmware has to expose its own composite HID interface that lets me inject cursor movement, click events and scroll actions programmatically. Implementation expectations ...

    My current workflow already relies on , but I’m hitting limits with its out-of-the-box functionality. The project centers on true custom feature development—expanding so it fits my exact use-case rather than forcing my process to adapt to the platform. The work starts with a quick review of the existing setup, followed by a short requirements session where we pin down what the new feature must do, how it should be accessed, and any guardrails around performance or security. From there, the task moves into design, coding, and rigorous testing inside a staging environment to be sure everything runs smoothly once promoted to production. Deliverables • Complete source code and configuration for the new feature • Clear deployment notes and end-user documentation ...
