IN THIS ISSUE:
Chaos Engineering Tools
Inject faults into infrastructure in a controlled manner to test its resilience.
Database Disaster Recovery
Safeguard your MariaDB or MySQL systems with backup, replication, and recovery strategies that let you get your databases back online quickly in an emergency.
NAS Disaster Recovery Tools
We take a practical look at disaster recovery approaches suitable for smaller NAS systems and highlight the tools offered by vendors, along with a collection of Linux and open source tools.
Win Server 2025 DR
Built-in tools can set up resilient backups; reset roles selectively for Active Directory, Hyper-V, and Certificate Services; and automate processes with PowerShell, wbadmin, and event triggers.
Entra ID Data Backup
Data backup is often overlooked in Microsoft Entra ID. User accounts, groups, and Conditional Access policies need targeted protection.
Microsoft Dataverse
Various Power Platform modules use Dataverse to store, manage, and evaluate information, making data available to Power BI, Power Apps, Power Automate, and Power Pages in a uniform environment.
Microsoft Power Pages
Create dynamic, secure, and data-driven websites on the low-code Power Pages platform with external data from Microsoft Dataverse.
Integrating AI Systems
The Model Context Protocol helps standardize and simplify communication between applications and large language models.
Driftwatch
Learn how to detect and eliminate security drift across Kubernetes clusters.
Neko Virtual Browsers
Virtualize browsers, applications, and desktops on Linux to support local or network-based access.
BunkerWeb WAF
This web application firewall provides a low-threshold entry point for hardening virtually any application with meaningful, application-independent safeguards.
Secure DNS Protocols
The Internet's address book is often used in plain text. Fortunately, modern DNS protocols offer many improvements.
Ceph Performance Tuning
Administrators regularly criticize Ceph performance tuning, because some elements can be tweaked effectively, while others are difficult or impossible to fine-tune. We look at how to measure performance, compare actual requirements with what is technically possible, and determine realistic objectives.
Ceph Dashboard
To hardcore command-line enthusiasts, the Ceph Dashboard might sound like a frowned-upon point-and-click gadget, but the advantages simply cannot be ignored.
Ollama and Open WebUI
Build a streamlined local AI stack with this open source duo. Docker Compose then helps you keep models and application data persistent, update safely, back up key files, and recover quickly if something breaks.
Industrial Wireless Standards
New wireless standards significantly expand the potential applications for wireless communication in industrial and IoT environments, but not every standard is suitable for every task.
