This is not a talk about speed coding, or writing thousands of lines of crappy code in a weekend. This is a talk for software craftsman who test drive clean code, but who also have a nagging feeling: “Man, I know I could be doing this faster.” We’re going to discuss everything from touch typing, to keyboard shortcuts, to faster pair programming techniques, to hardware, to build automation, to staying in the zone, to caffeine consumption, to ergonomics, to music and headphone selection, refactoring, language and framework selection, tech debt management, rapid prototyping, whiteboard design sessions, back of napkin mockups, guerilla tactics for getting in front of requirements and staying there, and what to do when you’re 30 lines down a stack trace and someone wants to tell you about something funny their kid did over the weekend.

Nothing Matters More Than Coding Fast

(Please hold questions until the end)
DISCLAIMER
There are things that matter more than coding fast
What is “Coding Fast”?
Coding Fast
Continuously adding business value
over an indefinite period of time
while maintaining high quality code
at a pace that exceeds expectations
Typical Mentalities
“The thing is, Bob, it's not that I'm lazy. It's just that I just don't care. It's a
problem of motivation, all right? Now, if I work my ass off and Initech ships a few
extra units, I don't see another dime.
So where's the motivation? ”
Yeah….I’m going to need to see your estimates in
Jira…m’kay?
Your Motivation to Code Fast
How to Code Fast
Get in the Right Mindset
Eliminate Distractions
Get Comfortable
Touch Type
In 100 years, I know they’ll invent a better
way to do this…
Sub-Second Builds
Use an IDE
Master Keyboard Shortcuts
Ctrl+Tab+1 Alt+Ctrl+Insert Ctrl+Shift+F Down Arrow Enter Ctrl+F4
Ctrl-C Ctrl-Tab Ctrl-V Alt+Tab
F5!!!!!
Be Extremely Knowledgeable
I like turtles
Somewhere between reading the API spec
and building a TODO’s app on my own time
Whoa! How did you know that?
I like turtles
var args can only be the first argument, no the last, no the first…but
only if they’re the only argument…right?
OMG JFGI
Don’t Work in Crappy Code
Aggressively Pay Down Tech Debt
We are so getting spot bonus’ for getting this
thing to market a month ahead of schedule!
Extract Method!
Push Down! Extract Local
Variable!
Inline!
Extract Class!
I told them we needed to better encapsulate the
concept of order refunds before we tried to support
different currencies!
Find Creative Solutions
She’s just not ready captain!
Must have more…features…
I like turtles
OK, if we introduce a message queue and filter by last order
date that might work!
ManagerUtilFactoryHelper???
Re-Compose into New Features

Estimate Wisely
What you give as your estimate will set my
expectations for delivery date, and therefore my
perception of you coding fast or not.
What happens to me if I’m late? Nothing?
Cool! Then it’s whenever you want it
to be plus 50% contingency
It shall take 5 days, based on my vast
theoretical knowledge of enterprise systems
All we need is a LatePayment sub-
class. I could do it in less time than it takes
to estimate it
Pair with someone fast
Totally! I bet we’ll go twice as fast with 3 times better code quality and
zero bugs! Management will love us!
I read that pairing is better than coding on
your own in every situation! Let’s try it!
I’m totally over being preached to
about this Bob Fowler guy.
I’m totally over having to explain every design
decision I make to someone who’s never architected a system.
I still say Fluent Interfaces are Train Wrecks
Shut up and Pass me the
Keyboard
The presentation layer should have no knowledge of our persistence
model
But why add an extra layer of indirection?
Adapt
Questions?
