Step-by-Step Guide to Installing Jenkins on Rocky Linux 9 with HTTPS

0
·1 views

Jenkins, a widely used open-source CI/CD automation server, can be installed and secured on Rocky Linux 9 by following a structured setup process. The installation requires OpenJDK 21 as a prerequisite, with Jenkins added via its official stable DNF repository and GPG key. Once running as a systemd service on port 8080, the web interface is secured behind an Nginx reverse proxy using a Let's Encrypt SSL certificate. System resource limits are also tuned to handle heavier workloads, and automated backup configurations are put in place. The final setup delivers a fully functional Jenkins instance accessible over HTTPS, with a test job validated through both the web dashboard and the Jenkins CLI.

Developer Launches Self-Hosted Session Replay Tool Aimed at Startups and Side Projects

A developer has built TraceUX, a lightweight, self-hosted session replay tool designed for early-stage startups and side projects. The tool addresses a common pain point where founders cannot tell where users drop off, but existing solutions charge based on traffic, seats, or recorded sessions. TraceUX records DOM events and stores them on the user's own server, requiring no data warehouse or complex multi-service setup. It can be deployed via a binary or Docker container on a small VPS, with a short code snippet added to the target website. The project is open source and available on GitHub, with a live demo accessible for evaluation.

OpenAI Unveils Defense Factory, a Continuous AI Security Operations Model

OpenAI has publicly detailed Defense Factory, an agent-first, continuous security program designed to identify, validate, and remediate vulnerabilities across its own systems. The initiative originated from an internal security sprint that mobilized over 250 people across hundreds of service areas. Rather than treating security as a periodic review, OpenAI frames it as a closed-loop cycle with five linked stages: inventory, discovery, validation, ownership assignment, and remediation verification. The program features a dedicated architecture that separates control and data planes to support isolated, reproducible development environments. OpenAI intends to publish workflows and findings on an ongoing basis, positioning the model as a scalable reference for organizations deploying AI at scale.

How to Debug Phone Verification Failures in Game Account Recovery Flows

Developers building game account recovery systems often struggle to diagnose phone verification failures because send and verify steps are treated as unrelated endpoints rather than a single auditable trace. A robust approach involves creating a state machine that records each attempt with a unique ID, normalized phone hash, expiry time, and server-side status before any message is sent. Every transition — from code dispatch to carrier delivery to player verification — should be logged with timestamps and actors, without ever storing the raw code or full phone number. Linking a consistent attempt ID across send, delivery, and verify phases helps pinpoint exactly where a failure occurred, whether at the queue, the carrier, or the verification step. This structured tracing is especially critical in gaming contexts where accounts can represent years of purchases and progress, requiring a recovery flow that is both user-forgiving and resistant to takeover.

Mobile Money Idempotency Flaws Risk Double Charges as UEMOA Deadline Looms

With the BCEAO's September 30 deadline approaching for PI-SPI platform integration, many UEMOA development teams are writing payment code under pressure. A technical analysis of three mobile money providers — MTN, Wave, and Orange Money — reveals that only MTN offers a true idempotency key via its X-Reference-Id header. MTN's 409 conflict response is frequently mishandled by developers, who may interpret it as a failure and trigger a second payment request, resulting in duplicate charges. Wave has no idempotency header at all, requiring developers to build their own safeguards using the client_reference field. The article warns that these integration gaps are the kind of bugs that only surface in production, where real customer funds are at risk.
