The revenge of Linux
|
||||
========================
|
||||
|
||||
|
||||
|
||||
In the beginning of Linux they laughed at it and didn't think it could do anything. Now Linux is everywhere!
|
||||
|
||||
I was a junior at college studying Computer Engineering in Brazil, and working at the same time in a global auditing and consulting company as a sysadmin. The company decided to implement some enterprise resource planning (ERP) software with an Oracle database. I got training in Digital UNIX OS (DEC Alpha), and it blew my mind.
|
||||
|
||||
The UNIX system was very powerful and gave us absolute control of the machine: storage systems, networking, applications, and everything.
|
||||
|
||||
I started writing lots of scripts in ksh and Bash to automate backup, file transfer, extract, transform, load (ETL) operations, automate DBA routines, and created many other services that came up from different projects. Moreover, doing database and operating system tuning gave me a good understanding of how to get the best from a server. At that time, I used Windows 95 on my PC, and I would have loved to have Digital UNIX in my PC box, or even Solaris or HP-UX, but those UNIX systems were made to run on specific hardware. I read all the documentation that came with the systems, looked for additional books to get more information, and tested crazy ideas in our development environment.
|
||||
|
||||
Later in college, I heard about Linux from my colleagues. I downloaded it back in the time of dialup internet, and I was very excited. The idea of having my standard PC with a UNIX-like system was amazing!
|
||||
|
||||
As Linux is made to run in any general PC hardware, unlike UNIX systems, at the beginning it was really hard to get it working. Linux was just for sysadmins and geeks. I even made adjustments in drivers using C language to get it running. My previous experience with UNIX made me feel at home when I was compiling the Linux kernel, troubleshooting, and so on. It was very challenging for Linux to work with any unexpected hardware setups, as opposed to closed systems that fit just some specific hardware.
|
||||
|
||||
I have been seeing Linux get space in data centers. Some adventurous sysadmins start boxes to help in everyday tasks for monitoring and managing the infrastructure, and then Linux gets more space as DNS and DHCP servers, printer management, and file servers. There used to be lots of FUD (fear, uncertainty and doubt) and criticism about Linux for the enterprise: Who is the owner of it? Who supports it? Are there applications for it?
|
||||
|
||||
But nowadays it seems the revenge of Linux is everywhere! From developer's PCs to huge enterprise servers; we can find it in smart phones, watches, and in the Internet of Things (IoT) devices such as Raspberry Pi. Even Mac OS X has a kind of prompt with commands we are used to. Microsoft is making its own distribution, runs it at Azure, and then... Windows 10 is going to get Bash on it.
|
||||
|
||||
The interesting thing is that the IT market creates and quickly replaces new technologies, but the knowledge we got with old systems such as Digital UNIX, HP-UX, and Solaris is still useful and relevant with Linux, for business and just for fun. Now we can get absolute control of our systems, and use it at its maximum capabilities. Moreover Linux has an enthusiastic community!
|
||||
|
||||
I really recommend that youngsters looking for a career in computing learn Linux. It does not matter what your branch in IT is. If you learn deeply how a standard home PC works, you can get in front of any big box talking basically the same language. With Linux you learn fundamental computing, and build skills that work anywhere in IT.

Linux 的逆袭
|
||||
========================
|
||||
|
||||
|
||||
|
||||
Linux 系统在早期的时候被人们嘲笑，它什么也干不了。现在，Linux 无处不在！
|
||||
|
||||
我当时还是个在巴西学习计算机工程的大三学生，并同时在一个全球审计和顾问公司兼职系统管理员。公司决定用 Oracle 数据库实现企业资源计划（ERP）软件。我得以在 Digital UNIX OS (DEC Alpha) 进行训练，这个训练颠覆了我的三观。
|
||||
|
||||
那个 UNIX 系统非常的强大并且给予了我们堆积起的绝对控制权：存储系统、网络、应用和其他一切。
|
||||
|
||||
我开始在 ksh 和 Bash 里编写大量的脚本让系统自动进行备份、文件转移、提取转换加载（ETL）操作、自动化 DBA 日常工作，还创造了很多从各种不同的项目提出的其他的服务。此外，调整数据库和操作系统的工作让我更好的理解了如何让服务器以最佳方式运行。在那时，我在自己的个人电脑上使用的是 Windows 95 系统，而我非常想要在我的个人电脑里放进一个 Digital UNIX，或者即使是 Solaris 或 HP-UX 也行，但是那些 UNIX 系统都得在特定的硬件才能上运行。我阅读了所有系统的文档，还找过额外的书籍以求获得更多的信息，也在我们的开发环境里对一些疯狂的想法进行了实验。
|
||||
|
||||
后来在大学里，我从我的同事那听说了 Linux。我那时非常激动的从还在用拨号方式连接的因特网上下载了它。在我标准的个人电脑里装上 UNIX 这类系统的这个想法真是太酷了！
|
||||
|
||||
由于 Linux 不同于 UNIX 系统，它能在几乎所有的个人电脑硬件上运行，在起初，让它开始工作真的是非常困难的一件事。Linux 针对的用户群只有系统管理员和极客们。我为了让它能运行，甚至用 C 语言修改了驱动软件。我之前使用 UNIX 的经历让我在编译 Linux 内核，排错这些过程中非常的顺手。由于它不同于那些只适合特定硬件配置的封闭系统，所以让 Linux 跟各种意料之外的硬件配置一起工作真的是件非常具有挑战性的事。
|
||||
|
||||
我曾见过 Linux 在数据中心获得一席之地。一些具有冒险精神的系统管理员使用它来帮他们完成每天监视和管理基础设施的工作，随后，Linux 同 DNS 和 DHCP 服务器、打印管理和文件服务器一起攻城略地。企业曾对 Linux 有着很多顾虑（恐惧，不确定性，怀疑）和诟病：谁是它的拥有者？由谁来支持它？有适用于它的应用吗？
|
||||
|
||||
但现在看来，Linux 在各个地方进行着逆袭！从开发者的个人电脑到大企业的服务器；我们能在智能手机、智能手表以及像树莓派这样的物联网(IoT)设备里找到它。甚至 Mac OS X 有些 DOS 命令跟我们所熟悉的命令一样。微软在制造它自己的发行版，在 Azure 上运行，然后…… Windows 10 要装备 Bash。
|
||||
|
||||
有趣的是 IT 市场会创造并迅速的代替新技术，但是我们所掌握的 Digital UNIX、HP-UX 和 Solaris 这些旧系统的知识还依然有效并跟 Linux 息息相关，不论是为了工作还是玩。现在我们能完全的掌控我们的系统，并使它发挥最大的效用。此外，Linux 有个充满热情的社区。
|
||||
|
||||
我真的建议想在计算机方面发展的年轻人学习 Linux。不论你处于 IT 界里的哪个分支。如过你深入了解了一个标准的家用个人电脑是如何工作的，你就可以在任何机器面前使用基本相同的语言。你可以通过 Linux 学习最基本的计算机知识，并通过它建立能在 IT 界任何地方都有用的能力。
