It can be fun and productive to use the basic tools
Philosophy Demonstration Ruminations
Learn new technologies OR Learn new things about your technology
High impact with low ceremony
Framework light Test-driven No calculators
Light on framework
How much time do you spend In debugger? Waiting for build? On Stackoverflow?
Frameworks solve 80% of the job…
… and makes the rest 10 times as hard
Fast feedback cycle
“I can see how TDD works for toy examples…”
“… but how can we use it when we have all these really complicated technologies???”
(Hint: “all these complicated technologies” I think I see your problem right here... )
“Don’t use a calculator…”
Demo: Phonebook web app
What can you learn?
Test for web applications Specifying requirements with tests The difference between realistic slow tests (aka “integration”) and limited fast tests (aka “unit”) Dependencies in your tests What does the web server do? Refactoring shortcuts Growing design Alternatives to HTML templates (maybe)
Those are my principles, and if you don't like them... well, I have others. - Groucho Marx
Build your app this way?
Well, why not?
I am most likely insane
The reasonable man adapts himself to the world: the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man. - George Bernard Shaw
Understand what’s going on
«Don’t reinvent the wheel»
Are you using technology to solve your problems?
Or so that you don’t have to face your problems?
95 % test coverage
95 % test coverage 5-10 seconds < 1 day to create «framework»
SOAP: 1.Construct XML 2.POST on HttpURLConnection
Don’t just learn new technologies => Learn new approaches, techniques and features about the technology you use

Do not believe a thing because many people speak of it. Do not believe on the faith of the sages of the past. Do not believe what you yourself have imagined. After examination, believe what you yourself have tested and found to be reasonable - Buddha
