只写一些跟官方说明有出入或者遗漏的地方：
1. 旅行证拼音姓名要和美国护照相同
2. 领事认证申请人是小孩，代办人是父母。签名要用“小孩名 父XX代” 格式（最好不填，等工作人员告诉使用什么格式填写）
3. 领事认证可以回邮（至少跟旅行证一起办理的时候是这样的）
4. 一般不提供加急
5. 回邮信封地址from to都写自己家地址

SSH Through NAT with help of middle man

发表于 2017 年 2 月 17 日 由 pswzyu

With this method, you don’t need to do any modification on the middle man server. GatewayPorts setting is not required.

 

Run this on destination machine:

ssh -o ServerAliveInterval=60 -N -R <port on middleman>:localhost:<port on this machine, usually 22> <user>@<middleman server>

Run this on your local machine:

ssh -o ServerAliveInterval=60 -N -L <port on local machine>:localhost:<port on middleman server> <user>@<middleman server>

 

Then you can connect to localhost <port on local machine> which will take you to the destination server

Run X11 apps on BQ M10 Ubuntu tablet

发表于 2016 年 4 月 30 日 由 pswzyu

Seems like nobody talked about this method. So I’m posting it here.
First of all, install X11 apps using apt-get. You need to first remount your root as read-write:
http://askubuntu.com/questions/399709/install-with-sudo-app-get-install-doesnt-work-not-using-locking-for-read-only

Then, you can first start a builtin X11 app, for example the gedit app from scope. And then run this in terminal:
DISPLAY=:1 codeblocks

If you want to run Qt apps, see this first(export MIR_SOCKET):

[leetcode] Wildcard Matching

发表于 2016 年 3 月 10 日 由 pswzyu

最大的疑惑在于不使用递归， 而又有多个*号出现时的回溯重试问题。

看起来如果第二次遇到*号时覆盖上次遇到*号时记录的重试位置，但是实际上第二个星号之前的匹配已经可以保证成功了，并且更重要的是这时上个星号匹配了多少字符已经无关了， 第二个星号可以吃掉多出来的字符。

比如下面这个例子

aababaababab
a*ab*ab

pattern中第一个*ab是匹配的哪个ab并不重要（只要不是最后一个就行，一般匹配第一个遇见的就好了），因为第二个*会吃掉多余的ab， 并且保证pattern中最后一个ab能够“够”到字符串的结尾。

User OpenCV Java With Tomcat and solve “already loaded in another classloader”

发表于 2015 年 8 月 11 日 由 pswzyu

This article is tested on Eclipse Mars Release, tomcat 8.0.24, opencv 2.4.10, Windows 8(shame, but… should be similar on linux)

Nearly all the articles on web point to this: http://wiki.apache.org/tomcat/HowTo#I.27m_encountering_classloader_problems_when_using_JNI_under_Tomcat

This is a good answer and explained what should you do to solve the problem. However, for opencv, the opencv-xxxx.jar does not load the native library from inside the classes in the jar package. OpenCV document asked developers to load the native lib from their code. For example:

public class SomeClassUsesOpenCV {
	static {
		System.loadLibrary("opencv_java2410");
	}
}

To solve this delimma, I created a java project called OpenCVLoader, and created a single class called OpenCVLoader, in this class, use the static field to load the library. And then, pack this java project as a jar package. In Eclipse, you can use the export option of the project to easily export a jar package(for example, opencv-loader.jar). Put this in “apache-tomcat-8.0.24\lib”. Why this dir? Because this dir is under common class loader in catalina.properties, you can also config the shared.loader and put the jar package into that dir. Basicly, we are trying to avoid using app specific class loader to load the opencv lib.

Then, put opencv-xxxx.jar into the same dir with the opencv-loader.jar . Then, make sure your opencv_javaxxxx.dll/so is in the java.library.path. There are a lot of posts about this. However, there is something that I really need to mention. Just like the opencv-xxxx.jar which must be loaded by the tomcat non-webapp-specific class loader, this dll should also be loaded by the same class loads opencv-xxxx.jar. So, if you want to use the -Djava.library.path method, it should be in the command which starts the tomcat server. In eclipse, you can achieve this by going to run > run configuration… > Apache Tomcat > your_server_name_here and in Arguments tab, append -Djava.library.path=”D:\path_to_your_opencvxxx.dll”. If you don’t see any thing under Apache Tomcat tree node, start the server once, then a default configuration will be created.

Then, in the servlet class that you want to use opencv, use this instead the loadLirary thing.

public class SomeClassUsesOpenCV {
	static {
		// trigger the opencv loader static field
		// which leads to loading the opencv jni
		// there are many ways to trigger it, I just used this
		new OpenCVLoader();
	}
}

OK, now try to do some modification and save to trigger the tomcat reload.
