DISM (short for Deployment Image Servicing and Management) is a Microsoft built-in utility for installing, uninstalling, configuring, and updating features and packages in offline Windows images (including Windows PE, Windows RE and Windows Setup), that is, a system slimming tool.

Playing all kinds of old but classic emulator games on our computer has been no longer a difficult task for long, since there are so many dedicated emulators available. However, the downside is that to play games for different consoles you have to run specific emulators separately. This makes us feel cumbersome and inefficient. This is where the emulator frontends like GameEx come in, which is built to serve as a universal interface for most game emulators in existence.

MAME is arguably the best arcade emulator out there. Although it only supported CLI (Command Line Interface) at the beginning, and now it has a DOS-like operation Interface and supports mouse operation, but its usability is still very low, and it never provides GUI (Graphical User Interface). That's where a third-party GUI frontend like MAMEUI comes in.

Bootstrap is a concise, intuitive and powerful front-end development framework based on HTML, CSS and JavaScript libraries, cooperatively developed by the designers Mark Otto and Jacob Thornton from Twitter, which makes the Web development easier and more efficient. It became popular the time it was launched. Many companies including NASA, MSNBC have started to use this free and open-source project very early. Even some popular mobile development frameworks are developed on the basis of Bootstrap source code, just feature some improvements on performance.

Bootstrap is currently one of the most widely used Responsive Web Design framework, and a number of web development tools have started to support it. But the thing is, most of them design web pages in the editing mode of the source code, which is unbearable for designers who are used to carry out web design works with Dreamweaver and such completely visual tools.
