问题 With Toolkit.getDefaultToolkit().getScreenSize() I get the screen size. But usually this isn't the available size I have for my own program, because on the mac there is a menubar on top and on the bottom an iconbar. Windows also has an iconbar. So how do I get the real available space? 回答1: From Java forum: UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment(); Rectangle bounds = ge

问题 If I am building a graph on AWS Neptune with 20 million Nodes and 100 million edges, How much RAM and Disk space would I require? Can someone give me an rough order of magnitude estimate 回答1: Storage capacity in Amazon Neptune is dynamically allocated as you write data into a Neptune cluster. A new cluster starts out with 10GB allocated and then grows in 10GB segments as your data grows. As such, there's no need to pre-provision or calculate storage capacity prior to use. A Neptune cluster

问题 my web site displays images bigger than their original size. The images are 20% bigger than the original created with photoshop (for example), if an image's width is 200px, the browser display is 240px. So all my images are blured. Do you know why? 回答1: I've found the solution! Windows 10 has the default setting of dpi seted to 125% (search dpi into serach box and then look at "update text app and other elements"), this increase the dimension of everything in my monitor, so the images into my
