初尝 64位 linux kernel

机器是athlon64的, 不跑跑64bit linux实在不过瘾, 于是下了个linux kernel 2.6.22.5自己编译看, 一开始下载是想编译32位的, 但是启动时有点小问题, 中间会卡住, 要不断按开机键才能继续, 挺诡异的, 但是64位的编译好后竟然没有这个问题了, 比较有趣。

在编译前进行配置时倒是出了些问题, 由于我要在32位系统下编译64位内核, 是交叉编译, 不是很熟练, 查了半天在发现应该在make是加入ARCH=x86_64的参数。(ubuntu里习惯称amd64, 但linux内核里叫x86_64)

另外configure的时候也有问题, 我直接make ARCH=x86_64总报错, make ARCH=x86_64 config也不行, 后来想到, 现在的.config是按i386配置的, 可能跟64位的有冲突, 于是用make ARCH=x86_64 oldconfig重新配置, 别说, 还真问了几个新问题, 之后再make ARCH=x86_64就可以编译了, 最后别忘了编译模块,再都安装就好了。

现在运行挺不错, 但是aptitude不能找到64位程序, 还有待研究。

Determine Perspective Lines With Off-page Vanishing Point

In perspective drawing, a vanishing point represents a group of parallel lines, in other words, a direction. For any point on the paper, if we want a line towards the same direction (in the 3d space), we simply draw a line through it and the vanishing point. But sometimes the vanishing point is too far away, such that it is outside the paper/canvas. In this example, we have a point P and two perspective lines L1 and L2. The vanishing point VP is naturally the intersection of L1 and L2. The task is to draw a line through P and VP, without having VP on the paper. I am aware of a few traditional solutions: 1. Use extra pieces of paper such that we can extend L1 and L2 until we see VP. 2. Draw everything in a smaller scale, such that we can see both P and VP on the paper. Draw the line and scale everything back. 3. Draw a perspective grid using the Brewer Method. #1 and #2 might be quite practical. #3 may not guarantee a solution, unless we can measure distances/p...

Hardware Password Manager

[Updates 2025-01-20] The original blog post assumes that all passwords are stored in one password manager, and the password manager either unlocks everything or nothing (e.g. Keepass). After discussing with friends, I realized that if I use something like pass , and I use a hardware GPG token, I can actually store and sync all encrypted passwords to all devices, because I will only decrypt the passwords on demand, and the computer will not see the GPG private key. The compromise is that the computer will see the list of all password entries (e.g. accounts), as well as a few other issues . I've been using Keepass for many years. I don't use online password services because I cannot fully trust them. Besides, I may not always have Internet connection, which is why I also don't use a self-hosted service. Everything has been working fine, until I turn my paranoid knob to the max. Here's the thought experiment . The Imaginary Scenario Let's say I have 100 PCs for differe...

Installing Linux on Surface Pro 1g

Windows 10 will soon reach its end of life, and my 1-gen Surface Pro is not supported by Windows 11. I (finally) decided to install Linux to it. Fortunately, it's a not-so-easy nice adventure: The device has only one USB port, so I have to bring back my 10+-year old USB hub. My live USB drive cannot boot directly, I have to disable Secure Boot first, by holding Volume Up during boot. I think years ago I learned that booting on USB might not work through a USB hub, but fortunatelly it worked well with my setup. This is done by holding Volume Down during boot. Wifi adapter was detected in the live Linux environment, but not functional. And I don't have a USB-Ethernet adapter. Luckily, nowadays we have USB-tethering from Android phones, which works out-of-the-box. Originally I planned to following this guide to set up root on ZFS, however, the system froze when building the ZFS kernel module. Then I decided to just use EXT4, yet I still learned a lot from the guide about disk par...
