1、从应用商店下载安装最新版本部落游戏，安装后启动，随便点几下以生成存档，退出游戏。 2、游戏存档路径为C:\Users\(你的用户名)\AppData\Local\Packages\0EB8BD08.TheTribez_erk4rrwmt7jyt\LocalState\670F7B37\User-xxxxxxxx，使用winhex软件，打开存档，在ASCII中搜索“Gold:”“Gem:”，单词后跟着的数字就是金币和钻石的数量。用鼠标选中数字，左侧的16进制数值会对应选中，修改每一个两位数的个位数子为9，金币和钻石数量就会变成所有选中的两位数的个位数连起来的数值。 源自百度贴吧，源地址找不到了

查找下在 /usr/lib/R/etc/ 下的 Renviron 文件中。找到这一行 R_LIBS_SITE=${R_LIBS_SITE-‘/home/user/Archive/software/R/x86_64-pc-linux-gnu-library/3.0/:/usr/local/lib/R/site-library:/usr/lib/R/site-library:/usr/lib/R/library’} 当然上面包含XXX的路径修改成你希望的存储目录即可。 修改之后的再次在R中运行 libPaths() 命令的结果是: > .libPaths() [1] “/home/user/Archive/software/R/x86_64-pc-linux-gnu-library/3.0” [2] “/usr/local/lib/R/site-library” [3] “/usr/lib/R/site-library” [4] “/usr/lib/R/library”

假如我们要导入C:\Users\user\Desktop路径下的test.csv文件，则输入代码： read.csv(file = “C:\\Users\\user\\Desktop\\test.csv”) 默认情况下，R语言会认为第一行的是数据的标题，假如你的数据的第一行其实并不是标题，那么可以输入代码： read.csv(file = “C:\\Users\\user\\Desktop\\test.csv”,header = F) 下面的代码会将数据赋给对象Mydata： Mydata<-read.csv(file = “C:\\Users\\user\\Desktop\\test.csv”,header = F) 要查看Mydata对象里的数据，直接输入Mydata就可以了： Mydata 原始txt数据中有a、b两列数据，并且它们以“;”号作为分隔符，则： read.table(file = “C:\\Users\\user\\Desktop\\test.txt”,header = T,sep=”;”) 假如分隔符是其他符号，例如百分号“%”，则代码修改为： read.table(file = “C:\\Users\\user\\Desktop\\test.txt”,header = T,sep=”%”)
1、更新系统 sudo apt update 2、安装apache2和php5 sudo apt install apache2 如果出现路径锁定问题，使用以下命令 sudo rm /var/lib/dpkg/lock sudo rm /var/lib/apt/lists/lock sudo rm /var/cache/apt/archives/lock 3、安装postfix sudo apt install postfix 点OK确认，configuration选择默认的项：Internet Site，system mail name默认计算机名 4、重新载入postfix服务 sudo service postfix restart 5、安装dovecot sudo apt install dovecot-imapd dovecot-pop3d 6、重新载入dovecot服务 sudo service dovecot restart 7、安装squirrelmail sudo apt install squirrelmail 8、设置squirrelmail …
