This guide outlines the steps to create a cron-activated recovery script for OPNsense 25.7.7_4 to address DHCP outages. The script monitors connectivity, logs activity, and reconfigures the WAN interface as needed. It implements cooldown mechanisms to prevent reboot loops and integrates with the system’s configuration and scheduling functions.
Excel may appear simple, but it conceals a daunting data challenge: the hierarchical spreadsheet. Common among analysts, it presents issues like merged cells and hidden hierarchies that frustrate data processing. Enter xlfilldown—a powerful solution that transforms chaotic Excel files into clean, structured datasets for seamless analysis. By bridging the gap between visual reports and data integrity, xlfilldown revolutionizes the ETL process for data professionals.
The content discusses the performance and reliability of the xlfilldown tool, which efficiently processes large Excel datasets without excessive memory usage. A stress test processing 1,000,000 rows demonstrated rapid speeds—13,800 rows/sec for Excel and 44,700 rows/sec for SQLite—while maintaining deterministic and auditable output. This enhances data integrity and workflow trust.
The xlfilldown tool is a CLI and Python library designed for processing Excel data into SQLite or new Excel workbooks. It efficiently handles hierarchical and independent fill modes to maintain data integrity. Key features include row hashing, constant-memory processing, and raw ingestion options. Users can choose between CLI commands or a Python API for seamless integration into their workflows.

This post addresses the absence of a built-in WAN recovery mechanism in OPNsense 25.7.7_4, which can lead to internet connection loss requiring manual reboot. The author presents a DIY solution: a shell script that pings a reliable host, attempts to renew DHCP leases, and reboots the system if necessary. The script can be scheduled via cron for regular monitoring, enhancing network reliability.
The article addresses the “GIANT-LOCKED” boot issue and power recovery problems encountered when using OPNsense on HP T740 thin clients. The root cause lies in the legacy device probing by FreeBSD’s firmware, which can lead to system freezes and improper resets following a power cut. Solutions involve modifying the boot loader configuration to disable legacy device probing and manage ACPI settings, ensuring reliable system operation without external peripherals.
Pleasantly surprised when revisiting python packaging with setuptools and TOML in 2024.
