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.

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.

The .sas7bdat format is integral to SAS (Statistical Analysis System) software, widely used in data analysis and statistical modeling. This proprietary format excels in handling complex datasets, with features like:

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.

Nginx is a high-performance web server known for its efficiency, especially in terms of memory usage, fast startup times, and handling high concurrency. This makes it a popular choice for various internet projects.

ZeroTier offers a seamless way to create secure networks linking various devices like on-premise systems, cloud platforms, desktops, and mobile devices. This connectivity enables team members to collaborate from virtually anywhere in the world on any device.

This compilation is designed to be a handy reference for common Linux commands, helping both new and seasoned users navigate various system tasks with ease.

Building on our previous discussion of Trojan-gfw, this guide focuses on Shadowsocks-libev, an alternative proxy tool that encrypts traffic to evade ISP network censorship. However, users should be aware that Shadowsocks-libev may not be effective for bypassing Chinese network censorship and could result in the server's IP being blocked in mainland China.

This guide is dedicated to demonstrating how you can obtain free certificates essential for setting up HTTPS websites or configuring trojan proxies. By leveraging the efficiency of the acme.sh tool, you can quickly secure these certificates.

In this tutorial, I'll walk you through setting up a Trojan proxy, an effective tool for bypassing network censorship. Trojan-gfw is adept at disguising internet traffic as HTTPS, making it challenging for Internet Service Providers (ISPs) to detect your activities.

Arrays, as foundational data structures in programming, exhibit two key characteristics: zero-based indexing and contiguous memory allocation. This guide explores essential algorithms for manipulating arrays, demonstrating efficient solutions to common problems.

Recursive algorithms are a fascinating aspect of computer science, often leading to elegant solutions to complex problems. To better understand their time complexity, let's delve into a simple example question.

Docker revolutionizes the way we think about software deployment with its innovative platform-as-a-service (PaaS) model. Utilizing OS-level virtualization, Docker packages software in lightweight, efficient containers, offering a flexible and portable solution for software deployment.

Jekyll, an elegant and efficient static site generator, serves as an ideal platform for bloggers and developers looking for simplicity and power in their web projects. In this guide, I’ll take you through the process of setting up a Jekyll blog on a Macbook Air M1, leveraging the latest macOS environment. My aim is to provide a clear and concise path to get your Jekyll blog up and running, ensuring a smooth and straightforward experience. Let’s get started on this exciting journey of blogging with Jekyll on a powerful yet user-friendly setup!
