    My Jenkins pipeline for a Spring Boot 2.6.x service currently jumps straight to the Deploy stage. I need one extra, fully-scripted stage that will: • Archive the built JAR/ZIP, • Push that artifact to our Nexus repository, and • Trigger the deploy job by pulling the artifact back from Nexus into the Development environment. You’ll work directly in the existing Jenkinsfile (declarative pipeline) and wire any necessary credentials or repository definitions so the flow is completely automated. A quick readme or inline comments that explain variables, Nexus URLs, and how to extend the same logic to Staging or Production later will be appreciated. Acceptance criteria – Successful pipeline run shows the new stage after Build/Test, before Deploy. ...

    I’m a hands-on computer technician and CCTV installer who now wants to earn more from both trades, not just one.

On the computer side my main offer is fault repair, with a tight focus on operating-system-level problems—blue screens, boot loops, corrupted files, driver nightmares and the like. In parallel I design, install and maintain surveillance-camera systems for homes and small businesses. What I need is a practical roadmap that shows me exactly how to attract a steadier flow of clients, bundle and price my services smartly and scale up without sacrificing quality. Digital marketing ideas, local SEO tweaks, social-media campaigns, referral incentives, even partnerships with electronics shops—any mix that fits a modest starting budget and can be implemented ...

    I have a Node.js script that should live on my server and run continuously in the background, making periodic calls to our own internal services. The goal is to set it up so it behaves like a proper daemon: it starts automatically on boot, restarts if it crashes, and logs its activity so I can track both successes and failures. Here’s what I’m expecting from you: • Review the current code and confirm it is production-ready for long-running use. • Configure the server (Ubuntu) so the script runs as a service—systemd, PM2, or a comparable solution is fine, as long as it’s reliable. • Add concise logging and basic error-handling hooks; I want to see timestamped entries for every internal API call. • Document the setup steps in a shor...
