中文和英文作为主流的两种语言，其实有不小的区别。可以比较的点很多，其中一种比较从信息论的角度用香农熵比较科学地给出了数学对比，即中文汉字比英文字母拥有更高的的香农熵，或者说信息容量，信息密度，因此表达同样的信息需要用到的中文字符更少。这比较符合人们的主观感受，比如同一本书的中文版往往比英文版更薄。一个偶然的机会，我意识到可以从编写计算机程序的角度来做一个定量的比较，具体就是比较中...

ChatGPT-4

ChatGPT-4 之前对ChatGPT进行过两次测试，第一次是刚推出时进行的面试测试，纯粹从语言交流的角度来说其表现可以用惊艳来形容。第二次是用中英文数字转换为主题进行的编程测试，结论是ChatGPT并不真的会写代码。前几天看了GPT-4 Developer Livestream，对ChatGPT又有了进一步的了解。在视频的TaxGPT示例中，开发人员把计税的一大段规...

# 0.01粗糙版数字永生

——一ChatGPT功用乱想

0.01粗糙版数字永生最近ChatGPT开放了API，最新的定价也出来了，据说比以前的版本便宜了挺多。于是写了几段代码试着调用一下。跟网页版类似，提出一个问题（写一段话）就会得到一个回答。然而如果只是这样的话可以说毫无意义，用网页版就得了还写代码干啥? ChatGPT作为大语言模型，最擅长的是自然语言处理。很多人使用ChatGPT已有的知识来帮助写文章，然后自己修改，或者自己写...

Wordpress博客备份

——一个新旧交替的时期

想起来在Wordpress.com还开过一个博客，时间很短，只持续了3个月不到，三篇而已。回顾了一下时间线，适逢酝酿从旧公司离开，几个月后换了个城市开始新工作的时期。新工作开始后迎来一段全新并极为忙碌的旅程，说好的博客也没有再继续下去。彼时各方面有些停滞，心境的变化流于表面的大约体现在这几句话了。以前在CSDN有个Blog，前后两年多写了不少技术文章，至今也有四年多没有更新...
