It took me so long to find the cause of a memory leak in GoBlog. I thought it was smart to use a cache for prepared database statements. But I didn’t read the documentation and didn’t know that prepared statements need to be closed when they are no longer needed to free up the allocated resources. 🤦♂️ I finally fixed it by removing the prepared statement cache altogether. Less code, fewer problems in the future, and the cache wasn’t much of an improvement anyway. I also learned about the usefulness of memory profil … ⌘ Read more

你管这破玩意叫指针？
内存，通常被严谨地画成下面这个样子，一个下方是低地址上方是高地址的格子楼。
但我今天换种画法，画成下面这个样子。
每个格子代表内存中的 1 个字节（8 位），格子上的数字就代表内存地址，我也直接用 10 进制来表示了，免得 16 进制又算不明白了。
目前内存是完全空的，格子里没有任何内容。
试想一下，如果你忘掉所有的语法规则和编程规范，你会如何描述对这些内存格子的操作呢？
一、类型系统
很简单，往格子 3 处放个数字 29，往格子 6 处放个数字 38，就这么简单直接地描述即可。

everything has ipv6 though my ISP does not provide it. I have to tunnel it in from my VMs.
