Become a Hollywood movie hacker with these three command line tools
|
||||
======
|
||||
|
||||
|
||||
|
||||
If you ever spent time growing up watching spy thrillers, action flicks, or crime movies, you developed a clear picture in your mind of what a hacker's computer screen looked like. Rows upon rows of rapidly moving code, streams of grouped hexadecimal numbers flying past like [raining code][1] in The Matrix.
|
||||
|
||||
Perhaps there's a world map with flashing points of light and a few rapidly updating charts thrown in there for good measure. And probably a 3D rotating geometric shape, because why not? If possible, this is all shown on a ridiculous number of monitors in an ergonomically uncomfortable configuration. I think Swordfish sported seven.
|
||||
|
||||
Of course, those of us who pursued technical careers quickly realized that this was all utter nonsense. While many of us have dual monitors (or more), a dashboard of blinky, flashing data is usually pretty antithetical to focusing on work. Writing code, managing projects, and administering systems is not the same thing as day trading. Most of the situations we encounter require a great deal of thinking about the problem we're trying to solve, a good bit of communicating with stakeholders, some researching and organizing information, and very, very little [rapid-fire typing][7].
|
||||
|
||||
That doesn't mean that we sometimes don't feel like we want to be inside of one of those movies. Or maybe, we're just trying to look like we're "being productive."
|
||||
|
||||
**Side note: Of course I mean this article in jest.** If you're actually being evaluated on how busy you look, whether that's at your desk or in meetings, you've got a huge cultural problem at your workplace that needs to be addressed. A culture of manufactured busyness is a toxic culture and one that's almost certainly helping neither the company nor its employees.
|
||||
|
||||
That said, let's have some fun and fill our screens with some panels of good old-fashioned meaningless data and code snippets. (Well, the data might have some meaning, but not without context.) While there are plenty of fancy GUIs for this (consider checking out [Hacker Typer][8] or [GEEKtyper.com][9] for a web-based version), why not just use your standard Linux terminal? For a more old-school look, consider using [Cool Retro Term][10], which is indeed what it sounds like: A cool retro terminal. I'll use Cool Retro Term for the screenshots below because it does indeed look 100% cooler.
|
||||
|
||||
### Genact
|
||||
|
||||
The first tool we'll look at is Genact. Genact simply plays back a sequence of your choosing, slowly and indefinitely, letting your code “compile” while you go out for a coffee break. The sequence it plays is up to you, but included by default are a cryptocurrency mining simulator, Composer PHP dependency manager, kernel compiler, downloader, memory dump, and more. My favorite, though, is the setting which displays SimCity loading messages. So as long as no one checks too closely, you can spend all afternoon waiting on your computer to finish reticulating splines.
|
||||
|
||||
Genact has [releases][11] available for Linux, OS X, and Windows, and the Rust [source code][12] is available on GitHub under an [MIT license][13].
|
||||
|
||||
|
||||
|
||||
### Hollywood
|
||||
|
||||
Hollywood takes a more straightforward approach. It essentially creates a random number and configuration of split screens in your terminal and launches busy looking applications like htop, directory trees, source code files, and others, and switch them out every few seconds. It's put together as a shell script, so it's fairly straightforward to modify as you wish.
|
||||
|
||||
The [source code][14] for Hollywood can be found on GitHub under an [Apache 2.0][15] license.
|
||||
|
||||
|
||||
|
||||
### Blessed-contrib
|
||||
|
||||
My personal favorite isn't actually an application designed for this purpose. Instead, it's the demo file for a Node.js-based terminal dashboard building library called Blessed-contrib. Unlike the other two, I actually have used Blessed-contrib's library for doing something that resembles actual work, as opposed to pretend-work, as it is a quite helpful library and set of widgets for displaying information at the command line. But it's also easy to fill with dummy data to fulfill your dream of simulating the computer from WarGames.
|
||||
|
||||
The [source code][16] for Blessed-contrib can be found on GitHub under an [MIT license][17].
|
||||
|
||||
|
||||
|
||||
Of course, while these tools make it easy, there are plenty of ways to fill up your screen with nonsense. One of the most common tools you'll see in movies is Nmap, an open source security scanner. In fact, it is so overused as the tool to demonstrate on-screen hacking in Hollywood that the makers have created a page listing some of the movies it has [appeared in][18], from The Matrix Reloaded to The Bourne Ultimatum, The Girl with the Dragon Tattoo, and even Die Hard 4.
|
||||
|
||||
You can create your own combination, of course, using a terminal multiplexer like screen or tmux to fire up whatever selection of data-spitting applications you wish.
|
||||
|
||||
What's your go-to screen for looking busy?

用这三个命令行工具成为好莱坞电影中的黑客
|
||||
======
|
||||
|
||||
|
||||
|
||||
如果在你成长过程中有看过谍战片、动作片或犯罪片，那么你就会清楚地了解黑客的电脑屏幕是什么样子。就像是在《黑客帝国》电影中，[代码雨][1] 一样的十六进制数字流，又或是一排排快速移动的代码 。
|
||||
|
||||
也许电影中出现一幅世界地图，其中布满了闪烁的光点除和一些快速更新的字符。 而且是3D旋转的几何图像，为什么不可能出现在现实中呢？ 如果可能的话，那么就会出现数量多得不可思议的显示屏，以及不符合人体工学的电脑椅或其他配件。 在《剑鱼行动》电影中黑客就使用了七个显示屏。
|
||||
|
||||
当然，我们这些从事计算机行业的人一下子就明白这完全是胡说八道。虽然在我们中，许多人都有双显示器(或更多)，但一个闪烁的数据仪表盘通常和专注工作是相互矛盾的。编写代码、项目管理和系统管理与日常工作不同。我们遇到的大多数情况，为了解决问题，都需要大量的思考，与客户沟通所得到一些研究和组织的资料，然后才是少许的 [敲代码][7]。
|
||||
|
||||
然而，这与我们想追求电影中的效果并不矛盾，也许，我们只是想要看起来“忙于工作”而已。
|
||||
|
||||
**注：当然，我仅仅是在此胡诌。**如果实际上您公司是根据您繁忙程度来评估您的工作时，无论您是蓝领还是白领，都需要亟待解决这样的工作文化。假装工作很忙是一种有毒的文化，对公司和员工都有害无益。
|
||||
|
||||
这就是说，让我们找些乐子，用一些老式的、毫无意义的数据和代码片段填充我们的屏幕。（当然，数据或许有意义，而不是没有上下文。）当然有许多有趣的图形界面，如 [hackertyper.net][8] 或是 [GEEKtyper.com][9] 网站（译者注：是在线模拟黑客网站），为什么不使用Linux终端程序呢？对于更老派的外观，可以考虑使用 [酷炫复古终端][10]，这听起来确实如此：一个酷炫的复古终端程序。我将在下面的屏幕截图中使用酷炫复古终端，因为它看起来的确很酷。
|
||||
|
||||
|
||||
### Genact
|
||||
|
||||
我们来看下第一个工具——Genact。Genact的原理很简单，就是慢慢地循环播放您选择的一个序列，让您的代码在您外出休息时“编译”。由您来决定播放顺序，但是其中默认包含数字货币挖矿模拟器、PHP管理依赖关系工具、内核编译器、下载器、内存转储等工具。其中我最喜欢的是其中类似《模拟城市》加载显示。所以只要没有人仔细检查，你可以花一整个下午等待您的电脑完成进度条。
|
||||
|
||||
Genact[发行版][11]支持Linux、OS X和Windows。并且用Rust编写。[源代码][12] 在GitHub上开源（遵循[MIT许可证][13]）
|
||||
|
||||
|
||||
|
||||
### Hollywood
|
||||
|
||||
|
||||
Hollywood采取更直接的方法。它本质上是在终端中创建一个随机数字和配置分屏，并启动跑个不停的应用程序，如htop，目录树，源代码文件等，并每隔几秒将其切换。它被放在一起作为一个shell脚本，所以可以非常容易地根据需求进行修改。
|
||||
|
||||
|
||||
Hollywood的 [源代码][14] 在GitHub上开源（遵循[Apache 2.0许可证][15]）。
|
||||
|
||||
|
||||
|
||||
### Blessed-contrib
|
||||
|
||||
Blessed-contrib是我个人最喜欢的应用，实际上并不是为了表演而专门设计的应用。相反地，它是一个基于Node.js的后台终端构建库的演示文件。与其他两个不同，实际上我已经在工作中使用Blessed-contrib的库，而不是用于假装忙于工作。因为它是一个相当有用的库，并且可以使用一组在命令行显示信息的小部件。与此同时填充虚拟数据也很容易，所以可以很容易实现模拟《战争游戏》的想法。
|
||||
|
||||
|
||||
Blessed-contrib的[源代码][16]在GitHub上（遵循[MIT许可证][17]）。
|
||||
|
||||
|
||||
|
||||
|
||||
当然，尽管这些工具很容易使用，但也有很多其他的方式使你的屏幕丰富。在你看到电影中最常用的工具之一就是Nmap，一个开源的网络安全扫描工具。实际上，它被广泛用作展示好莱坞电影中，黑客电脑屏幕上的工具。因此Nmap的开发者创建了一个 [页面][18]，列出了它出现在其中的一些电影，从《黑客帝国2：重装上阵》到《谍影重重3》、《龙纹身的女孩》，甚至《虎胆龙威4》。
|
||||
|
||||
当然，您可以创建自己的组合，使用终端多路复用器（如屏幕或tmux）启动您希望的任何数据分散应用程序。
|
||||
|
||||
|
||||
那么，您是如何使用您的屏幕的呢？
