I've... exploited 0days you programmers wouldn't believe.

ROP shellcode on non-executable memory ran as the machine of Turing.
I watched Offset2lib pwns ASLR near the stack of kernel space.

All those bugs won't be fixed in time, like

自从微博上的鲁迅语录 bot 因压力停止更新后,有才的网友们又开设了许多 bot 账号,微博政治圈一幅后现代的繁荣景象。毕竟死人说话大概是没问题的,不过还是拭目以待。

Visual Studio Uninstallation sometimes can be unreliable and often leave out a lot of unwanted artifacts. Visual Studio Uninstaller is designed to thoroughly and reliably remove these unwanted artifacts.


Z80 CPU 为了和 Intel 8080 兼容,导致的奇葩寄存器设计——看着不少,要用的时候拿不出来——大概也是独特的历史了…… ​​​​

8080 上的每一个寄存器都有对应的 Z80 的寄存器——而且是两组。但是两组不能同时工作,只能轮流工作。有点类似交换区。当你需要使用第二组中的某个寄存器时,必须先把第一组的对应一个寄存器 swap out,用完了之后再 swap in.

这产生的直接后果就是用 C 语言编写程序,只能生成效率很差的机器代码。 PDP-11 的配置可比 Z80 豪华多了。

收拾房间,为了扫地需要拆除电源线数据线共 20 多条……电子时代的线材灾难。在特斯拉转世还没有出现之前,看起来要根本解决问题,首先需要设计 5V/12V DC 供电总线,摆脱所有的直流电源适配器;接下来再把 DVI, USB 3.0, 千兆以太网等外设接口集成到电脑桌里,最后让交流电线走线槽…… ​​​​

Today, I accidentally restarted my server SSH daemon while being __inside__ a network namespace. I didn't realize it until I logged out, and noticed the SSH was gone on LAN, ouch🙀!

It usually means I would need to physically reach the server with a monitor and keyboard, what a trouble!

(but, see next...)

哈哈哈哈哈哈哈哈哈哈哈哈哈哈 ​
