1. Press 'C' to clone and move it to projector
2. Press 'P' to show these here presenter notes

### 40 minutes + break + 40 minutes

### Ideas for next time

When I said "now work together", people didn't know exactly how to pair.
Try these ideas from Llewellyn:

- Strong-style pairing
- Setting a 4-minute timer (and switching seats when they switch roles)
- Mobbing instead of pairing

---

We'll be pairing. Do we have enough machines?

### Not Required

- Knowing how to code

### Required

- Knowing how to edit text

## [agiletestingdays.com/code-of-conduct](http://www.agiletestingdays.com/code-of-conduct/)

**Not** to prevent behavior we don't like -- nothing can -- but

To remind ourselves, when we see some, how _we'll_ want to behave.
]

It's a cognitive aid:

Declaring our intentions helps us live up to them.

### Key features

1. "Harassment includes..."
2. "If you..."
3. "If a participant engages in harassing behavior..."

### Homework

Build shared understanding: Find someone to help you write a few Gherkin examples for this Code of Conduct.

(Extra credit: Figure out how to automate them.)

---

### Not

1. Dev
2. Ops

What then?
]

1. Automation
2. Collaboration

Maybe you've heard about Docker, Chef, Puppet, Ansible...

But this here is _Agile_ Testing Days.
]

---

In pairs, we're going to:

### Iterate

- "Code" (edit text)
- "Deploy" (run a program)
- Fix
- Repeat
]

---

## Two options:

### 1. Not your thing? Cool, find something else

### 2. Sounds good? Cool, find your new pair partner

VirtualBox how-tos:

- File -> Import Appliance...
- Username/password: "devops"/"devops"
- Prefer SSH? Log in on the console once and follow instructions
- Got a non-US keyboard? Follow instructions on the console

## Self-organize

One of you is **Dev**, the other **Ops**. Play a role you don't know well.

## Dev

Run this command (the prompt is `$ ` -- don't type that part)

```sh
$ ./printlabels addresses0.csv
```

Looks good? Let's go to production!
]

---

## Ops

Run this command:

```sh
$ ./printlabels addresses1.csv
```
]

---

## Ops

Run this command:

```sh
$ ./printlabels addresses1.csv
```

## How'd that go?
]

---

## Dev

We better fix it.

Open `printlabels` with `nano`, `vi`, `emacs`, or any other text editor.

I'll show you which line to change.
]

???

```sh
$ cd ~/Documents/trees/devops-dojo
$ git checkout state-0
$ git crawl master
$ git show --decorate
```

---

## Dev

When you're ready:

```sh
$ ./printlabels addresses1.csv
```

Looks good? Let's go to production again!
]

---

## Ops

```sh
$ ./printlabels addresses2.csv
```
]

---

## Ops

```sh
$ ./printlabels addresses2.csv
```

## How'd that go?
]

---

Let's discuss. Some questions:

## 1. Perl?!!1

## 2. How unrealistic was that workflow?

## 3. Who has a real-world story to share?

## Work _together_

First, fix that bug. I'll show you how.

When you're _both_ satisfied, go to production:

```sh
$ ./printlabels addresses2.csv
```
]

???

```sh
$ git crawl master	    # to state-2-break-*
$ git crawl master	    # to state-3-fix-*
$ git show --decorate
```

---

## Work _together_

There's an `addresses3.csv`. Try it:

```sh
$ ./printlabels addresses3.csv
```

It's supposed to look different. I'll show you how.

When you're _both_ satisfied, go to production:

```sh
$ ./printlabels addresses3.csv
```
]

???

```sh
$ git crawl master	    # to state-4-break-*
$ git crawl master	    # to state-5-fix-*
$ git show --decorate
```

### What helps us do well at work

- Standardize deployment and monitoring
    - (Or else design monitoring in)
- Templatize service creation where possible
- Dev can deploy and support their own code
- Communicate and monitor performance requirements (and other <a href="https://en.wikipedia.org/wiki/Non%2Dfunctional%5Frequirement">ilities</a>)
- Not needing to have a "code freeze"

### What to try when we're back at work

- Define criteria for rejecting a "fix" that might make things worse
- When Dev thinks a feature might be "done", demo it and test ASAP
- Pair (local or remote) to shorten feedback loops
- Continuous Integration

## Come see me perform tonight:

1. An act (with Bob, Jack, and <a href="https://twitter.com/mheusser">Heusser</a>) related to these names and addresses (!)
2. A solo act involving spoken-word poetry (possibly bad (possibly intentionally))
