I recently switched from WordPress to Hugo. This post outlines the reasons behind my migration and provides a step-by-step guide on how to make the transition. Rethinking Why Use WordPress I began using WordPress in 2009 when static site generators were not prevalent, and WordPress was the go-to CMS for nearly everyone. However, since my blog had infrequent updates but high readership, I started reconsidering the use of WordPress. Five years ago, I decided to convert the WordPress site into static HTML and uploaded it to a CDN to accelerate access speed for users in mainland China.
It has been a long time since I last wrote a blog post. In the past few days, I updated the architecture of Infinite Script to accelerate the speed for Chinese users. In this article, I share the new architecture of our website with you. Optimizing a CDN for Static Content Delivery Static content does not change over a period of time. If it does change, the changes are predictable.
Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP) which was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion. IPv6 is intended to replace IPv4. IPv6 uses a 128-bit address, theoretically allowing 2128, or approximately 3.4×1038 addresses. The actual number is slightly smaller, as multiple ranges are reserved for special use or completely excluded from use.
Introduction This tutorial is a HowTo for setting up IPv6 NAT on an OpenWRT router. The information on the environment is listed below. Network Environment: China Education and Research Network Center with dual-stack IPv6 Network Device: NETGEAR R6100 (128M RAM) Firmware Version: OpenWrt Chaos Calmer 15.05 Install Dependencies for OpenWRT Login to the OpenWRT router via SSH and run the following commands: opkg update opkg install ip6tables opkg install kmod-ipt-nat6 opkg install iputils-tracepath6 Setup IPv6 for Local-area Network Edit /etc/config/network, and add the following lines in config interface ’lan':
Introduction Note: This guide was tested using Ubuntu Server 14.04.4 LTS. This is a HowTo for setting up Upside-Down-Ternet on Ubuntu. Basically, when a user browses the web, all the images are flipped upside-down. While it’s not useful, it’s quite a good April Fool’s prank. The process uses a transparent proxy, web server, and script to flip the images. Web traffic is routed to the proxy, instead of the default gateway, which is intercepted by the proxy which then downloads and modifies the images and then serves them back to the client browser.
Introduction Nginx is one of the most popular web servers in the world and is responsible for hosting some of the largest and highest-traffic sites on the internet. Tengine is a branch of Nginx which is created by Alibaba Inc. MariaDB is a database server developed by some of the original authors of MySQL and offers drop-in replacement functionality. Prerequisites Before you begin this guide, you should have a regular, non-root user with sudo privileges configured on your server.
Consistent hashing is a special kind of hashing such that when a hash table is resized and consistent hashing is used, only K/n keys need to be remapped on average, where K is the number of keys, and n is the number of slots. In contrast, in most traditional hash tables, a change in the number of array slots causes nearly all keys to be remapped. Consistent hashing achieves the same goals as Rendezvous hashing (also called HRW Hashing).

HTTP Protocol

What’s HTTP? HTTP stands for Hypertext Transfer Protocol. It’s the network protocol used to deliver virtually all files and other data (collectively called resources) on the World Wide Web, whether they’re HTML files, image files, query results, or anything else. Usually, HTTP takes place through TCP/IP sockets (and this tutorial ignores other possibilities). A browser is an HTTP client because it sends requests to an HTTP server (Web server), which then sends responses back to the client.
