Interuptions (Etsy)
-------------------

Fallacies
Adding third task triples error rate
- Simplify
 - How work comes in
 - Social media things
 - You are addicted to notifications
XKCD - Two accounts, work and play
Find out company priorities
- Do tasks related to priorities

Final thoughts:

Use fewest number of tools
- Flexible tools
Take responsibility
Have a team "liason" for other groups
- But be careful of siloing
#warroom - don't have to find people

Lots of smaller tasks - more dopamine

Communicate
Validate - Better way to do it?
         - Priorities compared to current work
Designate - Match skills with task (Maybe get some tips)

Correct stress level - "I've got tons of time" / [Overwhelmed]


Tracking Performance @patmeenan
--------------------

-WebPageTest

SOLR
Varnish/Memcache

Edge-caching (CDN)

Real user monitoring (RUM)
- With beacons
- Google Analytics / New Relic etc

"Representative pages" <- Be careful of caching

Latency more important than bandwidth (esp over 2mb/s)

- Really worth testing on real mobile devices

- Probably real 3G / simulated 3G not a problem (Real has a more unreliabale connection)

- Test from last mile (Not from data center)

All images (Above fold) loaded
- Instead of onLoad
[Can use Graphite]

Marcelle - NPM wrapper for webpagetest

tsviewdb <- visualiser for page speed (from Google)

*** Whatever you measure, people will optimise for. ***

"Speed index" <- Best guess at page load speed (a "taikan")


Networking
----------

Bandwidth + Latency ~= Performance

*** Latency = Every millisecond counts ***

"Navtiming"

setSiteSpeedSampleRate = 100 <- protip (For Google Analytics)



Building mobile app lab
-----------------------


Kylie - js instrumentation for your website

AT&T ARO <- Mobile (Radio)
