让LaTeX支持utf8

买了直通车，可以下到cyberbit.ttf了，于是想试试utf-8的LaTeX

步骤是：

1.到http://www.unruh.de/DniQ/latex/unicode/下载安装unicode.tgz
这一步我没有做，我是用apt装的latex-ucs

2.到ftp://ftp.netscape.com/pub/communicator/extras/fonts/windows/ 下个cyberbit.ttf
copy至/usr/share/texmf/fonts/truetype/CJK

3.下载http://edt1023.sayya.org/tex/ipeucs/cyberb.sh，放在临时目录下，并把cyberbit.ttf也拷过来，运行cyberb.sh

4.依下表将生成的文件/目录拷到对应位置
tfm /usr/share/texmf/fonts/tfm/CJK/cyberb
enc /usr/share/texmf/pdftex/enc
cyberb.map /usr/share/texmf/pdftex/config/cyberb.map

注意，第一行表示把生成的tfm目录中的所有文件拷到/usr/.../cyberb/中去，第二行类似

5.在/usr/share/texmf/pdftex/config/cyberb.map末尾加上一句
map +cyberb.map

6.好像需要在/usr/share/texmf下运行texhash,不知道是否是必需的。

这样就弄完了

本来ucs的doc中说使用方法是
\usepackage{ucs}
\usepackage[utf8]{inputenc}
然后文档中直接打中文就行了
但是我这不行

我发现CJK的utf8可以用了，方法是
\usepackage{CJK}

...

\begin{CJK}{UTF8}{song}
中文
\end{CJK}

当然了，tex文档要以utf8编码保存

字体还行吧，我对字体美观程度要求还不算高。
以后再研究研究怎么弄ucs

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...

ESP32S3: Flash Encryption and Secure Boot

Flash encryption and secure boot are useful security features for ESP32S3 chip. While not perfect, they definitely make it harder to extract the secrets in the chip. However, it is tricky to enable both features at the same time. The topic is actually discussed in the official documentation: ESP32S3 Security Features Security Features Enablement Workflows Especially, the second one mentioned it is recommended to enable flash encryption before secure boot. But I still find the documentation confusing. In the end I was able to successfully enable both, here's my findings. My Understanding After my adventure, here's what I think could have worked. WARNING, this is untested. Follow Security Features Enablement Workflows : Burn all the keys, as long as their purpose eFuses and read/write protections Burn other security eFuses, but DO NOT burn ENABLE_SECURITY_DOWNLOAD in the middle, which is mentined at the end of the instruction for both flash encryption and secure boot. Burn...
