前言

一个月前马斯克开源了自家的大语言模型 grok-1 并顺带着嘲讽了一下 OpenAI，想看看 OpenAI 关于 “Open” 的部分。

这波我肯定是站马斯克了，记得第一次听说 OpenAI 名字的时候，还以为这是一个研究 AI 的开源社区，因为它遵循了 OpenCV, OpenGL 这样的命名模式。

后来 GPT-4 需要一个月 20 刀的时候，也算是认清 OpenAI 的真面目了。

自从大语言模型诞生以来，中国民众想使用 AI 服务是真的难。可谓是双向卡脖子，一方面阿美丽卡的公司不对中国开放服务。另一方面国民无法访问自由的互联网。

最近，ChatGPT-3.5 可以免注册使用了（它总算是 Open 了一小部分😂），也就是说对于我们来说又少了一道使用 ChatCPT 的门槛。

这篇博客介绍了一种访问 chat.openai.com 的方法。

Preface

A month ago, Musk open-sourced his own large language model grok-1 and took a jab at OpenAI, curious to see what part of OpenAI is actually “Open”.

I’m definitely on Musk’s side this time. When I first heard the name OpenAI, I thought it was an open-source community for AI research, since it follows the naming pattern of OpenCV, OpenGL, and so on.

Later, when GPT-4 demanded $20 a month, I finally saw OpenAI for what it is.

Since the birth of large language models, it’s been genuinely hard for Chinese people to use AI services. It’s a two-way stranglehold: on one hand, American companies don’t offer services to China; on the other, people can’t access the free internet.

Recently, ChatGPT-3.5 became usable without registration (it finally opened up a tiny bit 😂), which means one less hurdle for us to use ChatGPT.

This post describes a way to access chat.openai.com.

IEEE 802.11-2007标准仅在OSI模型的物理层和数据链路层的MAC子层定义通信机制。

Here is the CWAP Official Study Guide Chapter 1 (802.11 Overview) summary notes.

最近在看 Linux 中双向链表的实现，发现大部分代码都是能看懂的，和上学时学的内容基本一致。

什么头插法，尾插法啊乱七八糟的。

但我注意到有一点似乎不一样，在学校时，我们学的链表包括数据域和指针域，但在 Linux 中双向链表的节点是这样定义的：

1
2
3

struct list_head {
	struct list_head *next, *prev;
};

没有数据域

没有数据域的链表该怎么使用呢？

Recently I’ve been reading the Linux doubly-linked list implementation, and found that most of the code is understandable — basically the same as what I learned in school.

Head insertion, tail insertion, and all that stuff.

But I noticed one thing seems different: in school, we learned that a linked list node includes a data field and a pointer field, but in Linux the doubly-linked list node is defined like this:

1
2
3

struct list_head {
	struct list_head *next, *prev;
};

No data field

How do you use a linked list without a data field?

现在的工作可以说是一行代码也不写，WB 程序员，经历了才会懂。

为了避免手生以及进一步巩固基础知识，决定定期抄一抄代码。

从 Linux 核心工具 开始，学习如何优雅编程。

The current job can be said to involve writing not a single line of code. Only those who have been through it as a WB programmer can understand.

To avoid getting rusty and to further consolidate basic knowledge, I decided to copy some code regularly.

Starting with the Linux core utilities, let’s learn how to program elegantly.

想当年 jsdelivr 在国内还能用的时候， GitHub 就是免费小网盘。

现在虽然国内访问不那么流畅了，但是用来存一些小的琐碎的日志文件还是不错的。

为了实现自动化，使用 Python 参考 GitHub API 文档 封装了一些常用功能。

Back when jsdelivr was still usable in China, GitHub was a free little online drive.

Although access from China is not as smooth now, it is still good for storing small, trivial log files.

To achieve automation, I used Python and referred to the GitHub API documentation to wrap some commonly used functions.
