<p>Running a BitTorrent (BT) or Private Tracker (PT) server at home can be challenging if your home network doesn’t have a public IP. Public IPs are essential for direct peer-to-peer connections, which significantly improve torrent connectivity. However, with the right setup, you can achieve similar connectivity and even gain extra benefits, like access to IPv6 peers, by using a VPS and WireGuard.</p>

<p>The 2012 Mac Mini Server remains a popular choice for Proxmox Virtual Environment (PVE) installations. This model stands out for its upgradeability: it allows for both memory and storage upgrades, making it particularly versatile. It’s also the last Mac Mini model with this flexibility, as the 2014 model saw soldered RAM, limited CPU performance, and eventually, Apple’s transition to ARM architecture in later versions, which limits virtualization capabilities.</p>

<p>I got a Sony DPT-RP1 digital paper yesterday. It is such a great tool to read A4 PDF files due to its large screen. The only shortcoming is that it is the Japanese version. The Japanese version has Japanese and English language and input methods, the US version only has English language and input methods, and the Chinese version has Chinese and English language and input methods. When opening a book with Chinese chapters, the Chinese characters in the Table of Contents cannot be displayed normally, but the Chinese and American versions can do that.</p>

<p>In Linux systems, memory management is crucial for maintaining system stability and performance. One component at the heart of this process is the "Out-Of-Memory (OOM) Killer." This process steps in when your system is critically low on memory. It selectively terminates one or more processes to free up memory and prevent a system crash. However, the intervention of the OOM Killer can be disruptive, as it might terminate essential or high-priority processes.</p>

<p>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.</p>

<p>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.</p>
