I need a full-featured Video Management System that I can compile and run on a Linux environment. The solution must follow a clean server-client architecture, include 100 % source code, and scale reliably to at least 1 000 simultaneous camera streams drawn from a wide mix of global CCTV brands (ONVIF or equivalent interoperability is a must). Two core capabilities are non-negotiable: smooth multi-camera live view and fast, timeline-based playback of recorded footage. Everything—connection handling, recording, storage management, and UI—has to remain responsive even under heavy load. If you already support complementary functions such as motion-triggered recording or smart alerts, feel free to highlight them, but live view and playback come first. The initial focus will...

Your solution should include: 1. Real-time control loop that accepts attitude sensor data (e.g., IMU, encoders) and drives two-axis galvanometers and a MEMs array. 2. Acquisition logic capable of coarse scan, fine scan, and lock-on stages, with tunable parameters. 3. Tracki...
...deploy a full-featured SIEM for my strictly on-premises environment. The number-one goal is rapid threat detection and incident identification, so every decision— from log sources to correlation rules— must serve that purpose. The platform you propose (Splunk, QRadar, Elastic, Graylog, or another commercial/open-source stack) should pull logs from our firewalls, core network devices and Windows/Linux endpoints, normalize them, correlate events in real time and raise actionable alerts. I also expect intuitive dashboards for security posture, drill-down timelines for investigations, and the ability to automate first-response actions where sensible. Beyond the build itself, I’m looking for clear documentation and a knowledge-transfer session so my internal team c...

I want a small, well-structured toolkit of Bash scripts that automate three routine but sensitive tasks on my Linux servers and come with clear, client-ready documentation. The first script, , must read a pipe-delimited CSV (username|email|role|department) and for each line create the user, add them to the right primary or secondary groups, set a strong random temporary password, force a password change at first login, and log every step to both stdout and /var/log for traceability. The second, , should perform a quick security sweep: list all regular accounts, flag anything that holds UID 0 besides root, highlight users whose passwords never expire, and output a neatly formatted report that I can email or drop into a SIEM. The third, set_shared_permissions
