How I play Tetris on the mainframe
|
||||
======
|
||||
Here's how I compiled and play my favorite game on a mainframe by
|
||||
accessing a virtual Linux server.
|
||||

|
||||
|
||||
The ability to [run Linux on modern mainframes][2] opens doors to doing all kinds of things on the platform. An Apache HTTP server? Easy! A database? Would you like SQL or NoSQL? Kubernetes? Sure! As I concluded in [Linux on the mainframe: Then and now][3], all of the most popular Linux distributions for servers today have versions for the mainframe.
|
||||
|
||||
This is great news for companies whose mission-critical infrastructures are running on a mainframe, but what if you just want to play around with one? The first time I got a bash shell on an IBM LinuxONE, I installed the irssi chat client and showed all my friends on IRC the output of `/proc/cpuinfo` to show off that it was an s390x architecture system. At first, I was at a loss as to what to do next.
|
||||
|
||||
Then I thought it would be fun to use this huge computer to play a game. My first thought was [NetHack][4], but it turns out I could install that with a simple `apt install nethack-console`. No, I should compile something! For every computer architecture, you need compilers and interpreters written for that. With over 20 years of Linux on the mainframe, most compilers and interpreters you'd typically expect are already ported.
|
||||
|
||||
Growing up, one of my all-time favorite games was Tetris, so it was the logical choice for my experimentation. I found an open source Tetris game written in C called [vitetris][5] and gave it a try. It was just like compiling a C program on any other Linux server.
|
||||
|
||||
First, I needed to grab some dependencies. The mainframe was running Linux, so I could use my package manager to [install the build requirements][6], and I was well on my way.
|
||||
|
||||
Next, it was just a matter of grabbing the code and building it:
|
||||
|
||||
|
||||
```
|
||||
|
||||
|
||||
curl -LO <https://github.com/vicgeralds/vitetris/archive/v0.58.0.tar.gz>
|
||||
tar xvf v0.58.0.tar.gz
|
||||
cd vitetris-0.58.0/
|
||||
./configure
|
||||
make
|
||||
|
||||
```
|
||||
|
||||
And in no time, I was playing my favorite game!
|
||||
|
||||
`./tetris`

||||

|

As I said, it's exactly like building any other C program on a Linux server, but you're doing it on a mainframe.
|
||||
|
||||
Unfortunately, I don't have a mainframe in my garage (yet). Instead, I've done all of this on a virtual server hosted by Marist College through the [IBM LinuxONE Community Cloud][9] program. It gives you free access to an s390x architecture Linux server, with your choice of the most popular distributions. With this virtual server, you have access to experiment for 120 days.
|
||||
|
||||
If you are a representative from an open source project that is considering building your application for Linux on s390x, there's a program for you, too. When I'm not playing Tetris, my actual job at IBM is working with open source communities to do just that. You can put in a request for a permanent Linux virtual server for your community to use for development, whether that's doing manual tests to see if your application will build or formally adding it to your project's continuous integration system. I recommend starting with the Community Cloud to do some experiments, and then you can fill out [this form][10] to get the process of getting a permanent virtual server rolling.

我如何在大型机上玩俄罗斯方块
|
||||
======
|
||||
下面是我如何通过访问虚拟 Linux 服务器，在大型机上编译和玩我最喜欢的游戏。
|
||||
![Gaming artifacts with joystick, GameBoy, paddle][1]
|
||||
|
||||
[在现代大型机上运行 Linux][2]的能力为在该平台上做各种事情打开了大门。一个 Apache HTTP 服务器？很简单！一个数据库？你想用 SQL 还是 NoSQL？Kubernetes？当然！正如我在[大型机上的 Linux：过去和现在][3]中总结的那样，今天所有最流行的服务器 Linux 发行版都有大型机的版本。
|
||||
|
||||
这对那些关键任务基础设施在大型机上运行的公司来说是个好消息，但如果你只是想玩玩大型机呢？我第一次在 IBM LinuxONE 上使用 bash shell 时，安装了 irssi 聊天客户端，向 IRC 上的所有朋友展示了 `/proc/cpuinfo` 的输出，以炫耀这是一个 s390x 架构的系统。起初，我对下一步该做什么感到茫然。
|
||||
|
||||
然后我想，用这台巨大的计算机来玩游戏会很有趣。我首先想到的是 [NetHack][4]，但事实证明，我可以用简单的 `apt install nethack-console` 来安装它。不，我应该编译一些东西！对于每一种计算机架构，你都需要为其编写的编译器和解释器。Linux 在大型机上已有 20 多年的历史，你通常期望的大多数编译器和解释器都已经被移植了。
|
||||
|
||||
在我的成长过程中，我最喜欢的游戏之一是俄罗斯方块，所以它是我进行实验的合理选择。我找到了一个用 C 语言编写的开源俄罗斯方块游戏，叫做 [vitetris][5]，并试了试。这就像在任何其他 Linux 服务器上编译一个 C 语言程序一样。
|
||||
|
||||
首先，我需要安装一些依赖项。这台主机运行的是 Linux，所以我可以用我的包管理器来[安装构建需求][6]，然后我就顺利完成了。
|
||||
|
||||
接下来，就是获取代码和构建的问题了：
|
||||
|
||||
|
||||
```
|
||||
|
||||
|
||||
curl -LO <https://github.com/vicgeralds/vitetris/archive/v0.58.0.tar.gz>
|
||||
tar xvf v0.58.0.tar.gz
|
||||
cd vitetris-0.58.0/
|
||||
./configure
|
||||
make
|
||||
|
||||
```
|
||||
|
||||
不一会儿，我就开始玩我最喜欢的游戏了！
|
||||
|
||||
`./tetris`

||||

||||

|
||||
|
||||
正如我所说，这与在 Linux 服务器上构建其他 C 程序完全一样，但你是在大型机上做的。
|
||||
|
||||
不幸的是，我的车库里还没有一台大型机。相反，我在马里斯特学院通过 [IBM LinuxONE 社区云][9] 计划托管的虚拟服务器上完成了这一切。它让你免费访问一个 s390x 架构的 Linux 服务器，你可以选择最流行的发行版。通过这个虚拟服务器，你可以在 120 天内进行实验。
|
||||
|
||||
如果你是一个开源项目的代表，正在考虑在 s390x 上为 Linux 构建你的应用，也有一个项目适合你。当我不玩俄罗斯方块的时候，我在 IBM 的实际工作就是与开源社区合作来做这件事。你可以请求一个永久的 Linux 虚拟服务器供你的社区用于开发，无论是进行手动测试以查看你的应用是否会构建或正式将其添加到项目的持续集成系统中。我建议从社区云开始做一些实验，然后你可以填写[这个表格][10]来启动获得永久虚拟服务器的流程。
