About of this talk
productivity |prɒdʌkˈtɪvɪti| noun the ability to maximize the work done
while minimizing the effort spent
Ruby Programmer Bias DISCLAIMER

slightly unusual format
everything is timeboxed
I should involve you
Intro 4min Q&A 4min Q&A 4min Q&A 4min Q&A 4min
I. General 10min II. Work 10min III. Code 10min IV. Tools 10min
I General
1 Maintain three lists
1. ToDo: things you must do obligations, commitments 2. Watch:
things you have to remember follow up, wait for somebody, remind yourself 3. Later: things you want to do when you have the time
pick 3-5 items before bed write them down (index card)
do them on the next day
Once you start, you’ll be surprised how often you didn’t
get 3-5 significant things done during a day
Timers & alarms 2
flow |fləʊ| noun the mental state of operation in which
a person performing an activity is fully immersed in a feeling of energized focus, full involvement, and enjoyment in the process of the activity
use alarms to divorce yourself form the clock
Periodically checking the time breaks your flow and stresses you
timers can put pressure* on you * the good kind
of pressure
Seinfeld calendars 3
“We are what we repeatedly do. Excellence, then, is not
an act, but a habit.” – Aristotle
None
put a calendar on a wall choose an action to
reinforce a habit put an X on each day you perform the action don’t break the chain
Seinfeld calendars gamify habit acquisition. They can serve as a
good motivator.
Keep notes 24x7 4
capture insight summarize information enhance the thinking process
Always have ready means of taking notes around you.
a small moleskine a large moleskine a Dropbox folder a
large notebook
voice memos index cards wiki Evernote, etc.
Skim over your notes regularly. Do it on the bus,
during breakfast or even set up a reminder.
Control decision fatigue 5
decision fatigue |dɪˈsɪʒ(ə)n fəˈtiːg| noun phrase [In decision making and
psychology, decision fatigue refers to] the deteriorating quality of decisions made by an individual, after a long session of decision making.
Making decisions wears you down. It is paramount to separate
the important from the unimportant.
http://lifehacker.com/5944198/president-obamas-productivity-tactics
Avoid making decisions by establishing strict routines.
where to go for lunch? what to listen to? when
to check my mail? when to leave work? what to do next?
Learn how to learn 6
Our ability to learn is our most important asset as
knowledge workers
None
II Work
No instant messengers 7
Eliminating distractions is the key to flow and instant messaging
is the mother of all distraction
Turn Instant Messengers Off
Not replying doesn’t work, since messages can still distract you
the price of distractions is twofold time to deal with
the distraction time to recover previous context
Create a second account for work if you have to.
Don’t give it to anyone, except your colleagues (and your spouse).
carry this further: remove all notifications email, twitter, facebook, etc.
Use two browsers 8
Work Personal stuff
Even the small effort to open Firefox in order check
Twitter is enough to discourage me
Choose any two browsers you want. You can even configure
one with different profiles.
Each browser can be customized to the job at hand
The ToDo list 9
a specific way of using a ToDo list
start with an empty list write down what you have
to do pick an item and start it don’t interrupt - use the list pick another one when finished carry unfinished items to tomorrow
It is important not to interrupt your current task. It
is also important not to tax your brain with keeping track.
refactorings phone calls emails writing documentation taking notes
start of the day
end of the day
Schedule email checks 10
Designate specific time slots for dealing with email and process
it only during those slots
Dealing with unexpected email can distract you
Once you open your inbox, you don’t know how long
you are going to be there
Control your email - don’t let it control you
Always leave your inbox empty afterwards
The perfect schedule would be twice a day - in
the beginning and in the end. It is probably not realistic.
The Pomodoro Technique 11
my secret weapon
None
Touch typing 12
we are professional typists
Typing can be the bottleneck if your typing speed is
low
Micro-interruptions: slowing down to type something can break your train
of thought
OK speed: 80 wpm Good speed: 100 wpm * for
programmers
For results, just pick a typing tutor and spend 10
minutes a day practicing touch typing* * ten fingers, no peeking
do NOT stress your hands
There is little point in picking up an alternative layout,
especially if you are not a native English speaker * it gives you street cred, though
III Code
Utilize shortcuts 13
Using keyboard shortcuts lets you do more things in less
time and
all shapes and sizes
None
Introduce shortcuts gradually: 1-2/day
Create a cheat sheet and put it next to your
monitor
Reread the cheat sheet occasionally
some examples
^⇧↑ Select enclosing element ⌥⌘L Extract local variable Eclipse
None
^⇧↑ ⌥⌘L
None
⎋Q Pause current command ⎋H Open man page for current
command ⎋E Open current command in editor zsh
Selenium IDE to walk pages 14
Selenium ≠ Selenium IDE
When you cannot write a full-blown test, you can record
a macro to walk the functionality you are developing
Shell aliases 15
Create shell aliases for all the commands you run often
faster execution command customization making long commands useful
! rsc rake spec cucumber ! rdm rake db:migrate !
rmig add_users rails generate migration add_users ! be spork bundle exec spork
! tmux attach tmux -2 attach ! clj rlwrap --quote-characters=\”’\”
--command clojure clj
git log --graph --decorate --pretty=oneline --abbrev-commit --all
! git lola git log --graph --decorate --pretty=oneline --abbrev-commit --all
! spj bundle exec xvfb-run specjour --rsync-port=8081
OH MY ZSH https://github.com/robbyrussell/oh-my-zsh
Guard and watchr 16 * or their non-Ruby equivalents
Both monitor the filesystem of your project for changes and
react on certain triggers
Top usage: run the corresponding test when you save a
file
continuous testing
immediate feedback
There are other uses for Guard: compilation, static checking, linting,
uploading, checking out and so on...
None
Cache stuff locally 17
Cache oft-referenced materials (documentations, guides) locally
You still pay a penalty for accessing the Internet. As
a bonus, you can use it on an airplane.
Putting things within an arm’s reach makes you more likely
to use them
wget rake
Spike when uncertain 18
It is very hard to test-drive with unfamiliar technology, especially
frameworks
Shave?
spike |spʌɪk| noun a small test-free time-boxed throw-away exploratory solution
used primarily for learning
Get the speed hit by going cowboy on the code
Throw it away and TDD it up from scratch. Resist
the urge to keep it.
IV Tools
Automate the environment 19
Automate everything you can possibly automate
Automation can store knowledge: you reduce the things you need
to remember
shells scripts: zsh, bash, ... build tools: rake, make, ant,
... scripts: ruby, perl, python, ...
some examples
installing my configuration (dotfiles)
! git clone http://github.com/skanev/dotfiles ! rake install vim, zsh, tmux,
git, xmodmap, etc... ! rake vim:bundles:update updates my vim bundles
SICP study group
03/14.scm 03/tests/14-tests.scm
! rake generate[3, 14] create 03/14.scm - add a header:
; SICP exercise 3.14 generate 03/tests/14-tests.scm - add a test scaffold start continuous testing open both files in vim ! rake next
SSH key on a new machine
! install-key new-machine.example.org
Try carrying it to the extreme: you will waste time
in unnecessary automation, but get a lot better at it
Build your own 20
Build your own tools when the need for them arises
recurring usage one-offs
iPhone version of the Bulgarian railroad network screen scraping &
web.py
sites to check each day Ruby on Rails
everybody reads all commits every day comment on GitHub best
for me: start of day
github.com was slow and clumsy git log -p was hard
to comment on
$ git catchup
None
None
git shell less lesskey
recurring usage duct tape 㲗 small apps
tools for small apps sinatra.rb, Flask, PerlDancer redis, MongoDB Twitter
Bootstrap
one-off
6 cap colors 6 bowtie colors 4 ears patterns 96
versions 4 sizes of each
None
zsh imagemagick
Keep your one-offs somewhere - they make great references in
the future
Personalize your editor 21
step 0: pick a generic editor
Vim Emacs SublimeText/TextMate
IDEs are fine - your Java productivity in (say) Vim
will probably never be as good as it is in (say) Eclipse DISCLAIMER
Editors are great in environments where you don’t have a
good IDE - all the “cool” new languages, for example
As programmers, we live in our editors - all improvement
we can squeeze out of them are worth it
Popular editors have lots of plugins - this is a
good way to easily improve your workflow
Learn the existing tools 22
Play with as many tools as you can - if
you know what one does, you will understand the what is possible to build
Dive deep. Trying doing it the hard way. That way
you’ll learn best.
your editor git zsh awk & sed / perl curl
& wget tmux ImageMagick GraphViz
Learn from others 23
talk with your coworkers pair with them try their (crazier)
ideas
https://github.com/search?q=dotfiles dotfiles in GitHub
Play by Play https://peepcode.com/screencasts/play-by-play ScreenCasts Destroy All Software https://www.destroyallsoftware.com/screencasts

Publish it in GitHub, blog about it, or give a
talk. Put it out there - it will be useful for someone.
