杂记 20130401

  • 之前evince的快捷键乱套了,使用
    rm ~/.config/evince/accels
    复位
  • 定义了变量var又不用的话,gcc会报warning"unused variable",解法是
    (void)var;
  • VirtualBox中DNS不工作:运行
    VBoxManage modifyvm "VM name" --natdnshostresolver1 on
    Ref 
  • 一个讲c++11右值引用的link:http://thbecker.net/articles/rvalue_references/section_01.html 
  • Linux清除disk cache:
    sudo sh -c 'echo 3 > /proc/sys/vm/drop_caches' 
    Ref
  •  遇到错误screen-256color not found需要支持新的终端类型:找一台支持screen-256color的机器执行
    infocmp xterm-256color > screen-256color.ti
    把文件拷贝到目标机器后执行
    tic screen-256color.ti
    Ref
  •  最近从ibus换到了fcitx,起初是由于sogou发布了,不过后来还是卸掉了。anran主题不错。fcitx在firefox中光标跟随有点问题,按官方wiki说法打开preedit后就没事了。
  •  最近在vim里折腾youcompleteme这个补全插件,挺好用。顺便也装了vundle来管理插件,很不错
  •  vim更新.vimrc后想直接应用,执行
    so %

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...
