Vim Cheatsheet

Tue, 13 Jan 2026 17:38:50 +0800

Vim is a powerful command-line text editor that’s been around for decades, and it’s still widely used today. Whether you’re SSH-ing into a remote server or just prefer the keyboard-centric workflow, Vim is often the go-to choice. The learning curve can be steep at first — I remember the first time I opened Vim and couldn’t even figure out how to quit. But once you get the hang of it, the efficiency gains are real. This cheatsheet covers the essentials I use most often, and I’m trying to condense them.

Disable SIP on Macos

Sun, 12 Oct 2025 19:39:00 +0800

System Integrity Protection (SIP) is a security layer that limits even the root user from modifying protected parts of the system. Apple introduced it in OS X El Capitan to reduce the blast radius of malware and accidental system damage. In practice, SIP blocks writes to system locations, prevents runtime injection into protected processes, and restricts some kernel/system-level operations.

Sometimes I run a command and see ‘Operation not permitted’ despite sudo, SIP is often the reason. So I need to disable SIP temporarily.

How to Partially Clone

Thu, 21 Aug 2025 21:56:10 +0800

Mainland Network Circuits

Thu, 19 Jun 2025 22:24:36 +0800

The performance and reliability of internet connectivity to and from mainland China are determined by a complex web of different network circuits, each with its own characteristics.

We will explore the crucial differences between the standard public network backbones, like the workhorse 163 network, and premium, optimized lines like CN2. We’ll also explain what dedicated networks such as IPLC are and why they offer a completely different level of performance and privacy. By the end of this article, you’ll have a clear framework for understanding these circuits, helping you make more informed decisions whether you’re choosing a hosting provider, diagnosing network issues, or are simply curious about how the internet infrastructure in mainland China operates.

Cloudflare Warp

Fri, 06 Jun 2025 14:52:52 +0800

Frankly speaking, the first time I heard about Cloudflare is the service so called Cloudflare WARP which is provided by Cloudflare. Nowadays, you must have heard the fastest and private network can be provided by Cloudflare. If I say Cloudflare achieves the fastest object by the first step to visiting any website, the world’s fastest public DNS 1.1.1.1. You can probably guess the private provider, yes, that is Cloudflare WARP. So this article I will introduce the Cloudflare WARP further zero trust and how to use it.

The principle of Cloudflare SaaS Optimization

Wed, 04 Jun 2025 11:23:44 +0800

In common situation, when you use the cloudflare to resolve your domain name, and you choose to use the cloudflare proxy(the yellow cloud icon), then cloudflare would probably get your domain resources into their CDN, that could be a good thing, but as we know, the network in mainland has some special rules, so for the free tier user, the access to the resources in the CDN would be somehow worse, even rest. That means, if the user connect to the node which has high latency, the request will experience worse. So this article will introduce some methods to help your resources access to the cloudflare nodes which are optimized for the mainland.

Add Live Photo Effect to Hugo

Fri, 16 May 2025 16:15:56 +0800

Live Photos 作为最早 Apple 在2015年9月发布的 iPhone6s 和 6s Plus 中引入的特色功能，很快就在手机摄影领域独树一帜，收获了无数忠实用户，Live Photo 的特色在于，它不仅仅是一张静态的照片，用户在拍摄实况照片时，iPhone会录下拍照前后各 1.5 秒所发生的一切。在 24 年下半年，随着微信宣布支持实况照片，Live Photo 再次成为了各大应用以及手机厂商的焦点，在短时间内无法实现更好的 AI 叙事的当下，不少手机厂商将 Live photo 适配各大社交媒体视为这个季度的业绩救赎，最近我也在思考，是否可以在博客中添加这个 feature，以便可以更好地展示照片的内容，在经过一番仔细搜索之后，发现网上完全没有关于 Hugo 支持 Live photo 的任何讨论，因此我决定自己动手实现这个 feature，也就有了本篇文章。

Find the Formula Rendering Issue of Hugo

Fri, 18 Apr 2025 13:47:15 +0800

最近在写数学相关的博客的时候，发现 mathjax 的渲染效果不尽人意，经常会在渲染的时候出现非预期的渲染效果，虽然只是极个别的公式，对整体影响并不大，当然我可以放着不解决，继续进行接下来的事情，或者简单将公式通过截图的形式放在文章里，也无伤大雅。但是凡事得想长远，想本质，今天大可以为了这一个公式采用省事的方法解决，那么它不会是我写的最后一个公式，未来可能还会有更多，因为这是一个长期的问题，如果放任不管，可能下次遇到类似的问题，我可能还是会采用省事的方法解决，那么这个问题就会一直存在，所以我认为放下手头的事，集中解决这个问题是值得的。

The Invitation Only Mechanism: From Clubhouse to Manus

Fri, 04 Apr 2025 11:40:39 +0800

虽然自小就听到过会员制的概念，但是也仅限于超市或者药店作为一种鼓励积分的方式，亦或是理发店等固定销售半径的捆绑销售的手段。不同于现在人们所谈论“邀请会员制”的概念，关于“邀请会员制”，我认为英文中有一个非常有意思的词，叫做 exclusive，意思是“只，仅仅”，但是在礼物等场景中 exclusive 尝尝用来形容“特定的，独家的”，追根溯源，本质上都是一种排他性(exclusivity)的文化覆盖。

一次制造热点帖子引发的思考与总结。

CPU can only see the threads

Thu, 23 Jan 2025 23:36:22 +0800

In python, due to the GIL (Global Interpreter Lock), which is a mutex and ensures only one thread can execute at a time, so the multiple threads parallel execution is not supported under the CPython interpreter. But what about the multiple processes? What is the difference between them? How to choose the right method? Do you know the coroutine? Let’s explore it together.

Video Technology 101

Mon, 20 Jan 2025 11:01:09 +0800

Do you really understand the video technology? What is the frame rate, resolution, bit rate and their relationships? Do you know the parameters p and K in the terminology 1080p and 4K? Do you know how to describe the video quality? What is the Blu-ray Disc on earth? What the difference between the codec such as H.264/AVC, H.265/HEVC, AV1? You may notice the Apple ProRes in apple, so do you really understand what it for? Do you know the HDR and Dolby Vision? So why there are so many tailers such as .mp4, .mkv, .flv, etc?

Now this Video Technology 101 will introduce them to you.

The Main Kind of Message Queue

Sun, 19 Jan 2025 20:15:13 +0800

Message queues are a form of asynchronous service-to-service communication. They are important in enhancing a system’s scalability, reliability, and maintainability.

The Method to Manage Traffic

Sun, 19 Jan 2025 17:33:27 +0800

Do you know the basic method to manage the traffic? There are four methods: Load Balancers, Reverse Proxies, Forward Proxies, and API Gateways. And they have different features and usage scenarios.

The Different Kind of API Design

Sun, 19 Jan 2025 14:42:18 +0800

In the daily life, we often hear about different kind of API, such as REST API, GraphQL API, WebSocket, Webhook, RPC and gRPC even the SOAP, so do you know the difference between them? How to choose the right API for your project?

The Encode and Decode in Python

Sun, 19 Jan 2025 13:07:49 +0800

Do you really know the encode and decode in Python?

About the Systemd

Sat, 18 Jan 2025 22:06:14 +0800

It has been a long time since the linux used init to manage the startup process, such as sudo /etc/init.d/apache2 start or service apache2 start, but the init is serial. To address this issue, the systemd was born. The d is the abbreviation of daemon, which means the systemd is a daemon manager. The systemd substitutes the initd and becomes the default main process PID 1.

The Tips About Dockerfile

Sat, 18 Jan 2025 21:05:23 +0800

Normally, we often write a Dockerfile in the current directory.

The Dockerfile is a configuration file that describes how to build the image. You can refer to the official documentation^[1] for more details.
If you list more than one CMD, only the last one takes effect. So if you have multiple commands to run, you better write them in a script file.
Docker is not the VMware, there is no systemd in the container. Its startup program is the container application process. The container exists for the main process. Once the main process exits, the container loses its meaning of existence and thus exits. So when you execute multiple commands and if they are blocking, you better write the previous commands in nohup and the last command in the blocking command. (never use the command such as CMD service nginx start, the CMD only will execute as CMD [ "sh", "-c", "service nginx start"], when the sh is executed, the container will exit, the correct way is run it directly CMD ["nginx", "-g", "daemon off;"])

Deploy Github Pages With GPG Signing

Wed, 18 Dec 2024 23:25:21 +0800

I have been busy migrating my blog this week. Coincidentally, I learned that there may be cases of commit forgery on GitHub. Therefore, for security reasons, I added a GPG signature. However, when deploying Hugo, I encountered many problems regarding whether GPG signatures can also be used. Fortunately, I finally solved them.

GPG 101

Tue, 17 Dec 2024 20:26:57 +0800

GnuPG is a complete and free implementation of the OpenPGP standard as defined by RFC4880(also known as PGP). GnuPG allows you to encrypt and sign your data and communications; it features a versatile key management system, along with access modules for all kinds of public key directories. GnuPG, also known as GPG, is a command line tool with features for easy integration with other applications.

This article I will introduce the basic usage of GPG.

Housewarming 2024

So after a long time, I decide to restart my blog program. In my daily development, I have a lot of thoughts and ideas, thus I will write some documents to record them. But I believe that sharing is the best way to learn. A specific example is cryptography, which means the closing source algorithm is never the safest. Only algorithms that have been vetted by the public are truly secure.
