ubuntu flash 中文乱码的解决

症状是所有中文都显示为方块

网上搜了很多方法，看上去都很暴力。另外在https://bugs.launchpad.net/ubuntu/+source/fontconfig/+bug/207198有很多讨论。

所有的方法都集中在/etc/fonts/conf.d/49-sansserif.conf这个文件上，不是修改就是删除。

（以下为个人猜测）

这个文件的用途是给没有通用字体名的字体加上sans-serif这个名字，比如说我想在标题栏上使用Comic Sans, 但是如果出现了中文怎么办？一般对中文的支持都是在serif, sans-serif,monospace这三个列表里加上中文字体，但是如果我指定的是Comic Sans，系统如何知道去哪里找中文字体呢。

所以这个文件就有用了，它给没有制定通用字体名（sans,sans-serif,monospace之一）的字体强行加上一个sans-serif，这样看上去就比较合理了。

而flash是怎么回事我就不知道了，因为不是所有的flash上显示中文都是乱码，youtube上的是乱码。

我在~/.fonts.conf里给sans-serif列表前端加了两个字体，一个英文一个中文，中文在后，这样可以让两种语言都能正确显示（因为中文字体对应的字符集包含英文的）。但是结果是flash就认第一个，不能匹配到第二个。我猜是flash请求时的问题，当然也可能是fontconfig的问题。如果我去掉了第一个字体，flash倒是正常了，但是所有字符都用那个中文字体显示了，不爽，所以这个文件不能动。

至于sansserif.conf这个文件，直接删除自然是不大合理，不知道会匹配到哪里去。目前的临时解决办法是把最后那个sans-serif改成我指定的那个中文字体，想了一下从逻辑上讲的通。

但是这个毕竟不是办法，让一般用户改这个还是不合理。如果是flash的问题自然好办，如果不是的话，我觉得可以给50-user.conf更高一点的级别，让用户自由度更大。

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...

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...

Fix Google Security Code

Google Security Code (http://g.co/sc) is one type of 2-step verification. This is particularly useful when security keys and passkeys are not available. I have been using it in my LXC containers, until today I found out that it stopped working. It just kept saying "The code is invalid". It is easy to rule out some factors: The code works on other browsers on my laptop. The code works on other devices that are directly connected to the router. So it appears that Google also checks IP addresses besides the security code. Recently I have IPv6 enabled, so most devices that are directly connected to the router have both IPv4 and IPv6 addresses. But  I only enabled IPv4 for my LXC containers. So I guess when a code is generated by device A and used by device B, Google should be able to check that device A and device B are closely located. But in my case, IPv6 address appears on device A but not on device B, which may look suspicious. To fix the problem, I just needed to disable IPv...
