eva qq in ubuntu

花了两天才弄好eva

其实学校feisty的源可以直接安装配置eva的,只是我仍在用edgy且短时内不打算升到feisty.edgy源里没有eva.我不想为此修改source.list再update,否则倒是改回来就不好整了,于是从源里下了个deb安装,不过需要依赖很多高版本的库,但是edgy源里这些库的版本号不够...

于是编译安装吧

eva 官方论坛里有个源码包下载,不过我编译后不能正常登录,说"您所在ip不能使用旧版本之类"...关于这个信息,eva的调试信息出的都是16进制的,需要用16进制编辑器写一下再看.
后来查到可以修改src/libeva/evadefines.h,这就要查QQ版本号代码了,我从飘云QQ里搞来了个列表,不过跟这个.h里的定义有很大出入,我尝试了几个均失败了.

最后终于发现我一直在犯傻 -- feisty源里也有源码下载,而且是cvs版本的,比较新.于是乎编译安装,最后,哈!能登录了!

但是开始时字体有问题,我在网上搜,说是应该改kde系统字体,用kcontrol改(一开始我看成konsole了,搞了半天,莫名其妙),这个不必多说.

这样就能正常使用了,截图功能还不错,不过截图发送有问题,传文件也不行.不知道为什么,不过也没多大关系,当初Luma时也差不多.

最后对eva开发维护者表示感谢!

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...
