...a complete web solution that covers the public site, a feature-rich user panel, and a robust admin panel. For members, the panel must display a clean dashboard summarising current earnings, keep real-time track of both left- and right-leg referrals, and let users place withdrawal requests that flow straight into the back office workflow. Smooth navigation, responsive design, and solid session security are essential so distributors can manage their network confidently from any device. On the admin side I need full user management (create, suspend, edit and search accounts), automated binary commission calculation with manual override when required, and clear, downloadable reports that cover payouts, leg volume, and overall growth metrics. An intuitive interface here is crucial s...

We need to create a computer game using the GODOT engine within a month. Subject: An educational computer game about physics, focusing on mechanics (grades 8-9). The game should be set in a medieval style. You play as a character, complete tasks, and explore locations and levels. You'll also conduct experiments related to mechanics. We need to add a light plot, including quests with other players. The player must also collect scrolls containing various laws and formulas about mechanics, and after completing the experiment, they must answer a question on the topic to advance. There should also be monsters in some areas, and the player will have to fight them off. At the very end of the game, the player must defeat the main boss and reach the final riddle, which will conta...

...hub-and-spoke SD-WAN. The topology is straightforward—one headquarters that will act as the primary hub, a DR site that will serve as a secondary hub, and four branch offices that will connect as spokes. Here is what I need from you: • Design a Meraki architecture that introduces proper VLAN segmentation, Auto-VPN, traffic shaping, and advanced security while mapping cleanly to the existing IP ranges. • Produce a configuration set for MX security appliances, MS access/distribution switches, and any required SFP or PoE considerations so the cut-over is as close to “plug and play” as possible. • Create and document a migration plan covering staging, test, pilot, full production rollout, fallback steps, and post-implementation verifi...

...“Authentication error.” Here’s what I know so far: • The failure appears only while syncing orders from Shopify Admin—install flow and every other endpoint work fine. • I’ve triple-checked the shared secret, stepped through the signing logic, and hammered it with sample payloads, so the usual suspects look good. What I need is an expert who has already wrestled with Shopify’s embedded-app security model and can pinpoint why the computed digest diverges, update the signing/verification code, and prove that every order webhook or Admin API call passes the check reliably. A short hand-over note outlining the change is all the documentation I’ll ask for. Deliverable – A patched app (or pull request) where order-...

I need an experienced server-security specialist to review and harden my Hostinger VPS that will host general web content.

1- I purchased three airline tickets from Priceline: one for me, one for my fiancé, and one for her daughter. We were supposed to fly on Alaska Airlines from Washington, DC, to Los Angeles, CA. We arrived at the airport, checked our bags, and proceeded to the departing gate. However, by the time we got through security, the plane was already ready to depart, and the gate was closed. The agent advised us to call the airline to see if they could put us on a different flight. I called the airline, and they informed me they could not put us on another flight since we missed it. We were considered a no-show, which rendered our tickets invalid. They advised me to call Priceline for further instructions on what could be done. Priceline instructed me to go directly to the airline f...
