Creating a macOS USB Installer can be more challenging than its Windows counterpart, particularly when dealing with older macOS versions on the latest systems. For instance, I faced difficulties while attempting to reinstall macOS 10.7 Lion on a Mac Pro 2012 using a MacBook Air with an M1 chip and the latest macOS. This article aims to document the solutions I found for these challenges, which may help others facing similar issues.
Guide to Disabling Automatic APT on Debian for Low-Resource VPS
I recently acquired two budget-friendly Virtual Private Servers (VPS) from OranMe, one featuring a 0.1 CPU with 128MB RAM and the other a 0.5 CPU with 512MB RAM. These low-spec servers are not ideal for heavy usage but can be efficient for specific tasks. To maximize their performance, I chose Debian without a desktop environment, aiming to reduce system load.
However, I faced a challenge with the 0.1 CPU VPS, which struggled with the apt update and apt upgrade processes, significantly slowing down operations.
In the past weeks, both VPS servers experienced unexpected shutdowns, compromising their reliability. Server stability is crucial, and such shutdowns undermine their utility. I noticed a pattern of high CPU usage spikes preceding each shutdown on the control panel, leading me to suspect that these spikes triggered the VPS provider's auto-shutdown mechanism.
To investigate, I delved into the /var/log/system.log file and discovered that the high CPU usage coincided with the automatic execution of the apt periodic task.
Debian systems often include automated tasks for apt update and apt upgrade. While these tasks ensure the system stays updated, they can be resource-intensive, particularly on lower-spec servers like mine. Therefore, disabling these automatic updates is a practical solution for enhancing performance.

Step-by-Step Guide to Building Padavan Router Firmware
Padavan is a notable open-source firmware project, ideal for routers with MTK chips. While it's officially designed for certain ASUS routers, it can be adapted for most MTK chip routers (Ralink RT3883, MT7620, MT7621, MT7628) through configuration adjustments. This tutorial focuses on building Padavan firmware for the MI-NANO router, a device that, despite its impressive design, suffers from outdated official firmware and lack of IPv6 support.
