Demo and Demoscene
In Internet terminology, a demo is a non-interactive multimedia presentation. Demos are the work of computer enthusiasts who often spend many days (or even weeks or months) creating a demo that may not have any external motivation (such as money, or acclaim in the broader world). The typical demo creator (known as a demomaker) is a male between the ages of 15 and 30, typically a student who is identified by a pseudonym. Demomakers are part of a subculture called the demoscene, an underground community that is reported to number among its members the elite from the worlds of programming and computer-assisted composing and art. Because each demo may showcase several talents, demomakers with complementary skills often collaborate to form demogroups that create their own mystique and reputation. Demomakers gather frequently for demoparties, which are arranged around competitions. Some of the largest demoparties have assembled over 4,300 demomakers. The demoscene originated in Europe and is most active in Scandinavia, Denmark, Germany, The Netherlands, Switzerland, Poland and France, it is gradually making its presence felt in the rest of the world.
On the Internet, a packet monkey is someone who intentionally inundates a Web site or network with data packets, resulting in a denial-of-service situation for users of the attacked site or network. Packet monkeys typically use tools created and made available on the Internet by hackers. A packet monkey, unlike a script kiddy, leaves no clues, making the identity of a packet monkey more difficult to trace. In addition, a denial-of-service attack can be launched on a wider scale than attacks performed by script kiddies, making them more difficult to investigate. Hackers look down on packet monkeys. Because a packet monkey uses tools created by others, the packet monkey has little understanding of the harm that may be caused. Typically, packet monkey exploits are random and without any purpose other than the thrill of making an effect.
A hotfix is code (sometimes called a patch) that fixes a bug in a product. Users may be notified by e-mail or obtain information about current hotfixes at a software vendor's Web site and download the hotfixes. Quick Fix Engineering (QFE) is a newer Microsoft term for a hotfix.
热补是一段程序代码（有时也叫补丁），用于修正（软件）产品中的错误。用户可由电子邮件获得通知，或者从软件厂商的网站获得最新的热补信息并可下载热补。快速修正工程（ QFE ）是微软公司对热补更新的叫法。
