解决2K/4K高分屏下Vmware等虚拟机下Kail Linux界面显示问题为了使这个过程更容易，Kali 现在提供了 HiDPI 模式。在我们日常使用VirtualBox、Vmware workstation、Hyper-V等虚拟机安装使用Kali系统，在2K/4K高分辨率电脑下Kali系统界面显示太小，包括各种软件及命令终端字体均无法很直观的看出，影响我们的正常测试及使用。很多人会通过调整我们笔记本或台式机的系统屏幕分辨率设置，或者修改缩放显示比例等，还有尝试通过修改kali显示设置发现调整前后都没有任何变化，更有甚者会将虚拟化软件降级到老版本或者使用老版本Kali等等。阅读详情

一个web层程序，不如简单的登陆窗口，登陆之后，将用户的信息存于cookie或session当中，

请问，GUI程序是否能够访问在web界面中保存的cookie或session信息,能否给个例子
（我还有一个附加的问题：对于web start技术，我看了"轻松玩转Java Web Start"
这篇文章，可以用google收到，试验之后，也成功了，不过对里面的JCE相关技术，知识不是很能够理解，各位大侠，给小第一个提示）。
