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.
Installation and Automatic Upgrade of acme.sh
Begin by installing acme.sh and configuring it for automatic upgrades:
curl https://get.acme.sh | sh -s [email protected]
. .bashrc
acme.sh --upgrade --auto-upgradeIn 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.
Installing Trojan
Begin by installing the Trojan software:
apt install trojanArrays, 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.
Imagine an array nums of integers sorted in ascending order and a target integer. The task is to develop a function to search for target in nums. If target is found, return its index; otherwise, return -1.
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.
A straightforward approach involves using a loop. Here's how it's implemented in Java:
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.
To effortlessly install Docker on various Linux systems, including Ubuntu and Debian, you can use this handy automatic install script:
curl -fsSL https://get.docker.com -o get-docker.sh
sh get-docker.sh
