x Driven Design

Rebecca Wirfs-Brock talked about the various -DD:s out there. Coming from Smalltalk she's been writing several books on object orientation design, RDD being her baby.

RDD - Responsability Driven Design

• Roles
• Responsability
• Collaborations

informed tools and techniques

localize responsability

CRC - Candidate Responsabilities Collaborations

FDD - Feature Driven Design

Feature lists --> Feature by feature:

1. Domain walktrough
2. Design
3. Design inspect
4. Code
5. Code inspect

Design first week, code second.

TDD - Test Driven Development

1. Write simplest test
2. Run test and fail
3. Write simplest code that will pass
4. Run the test and pass

"Design between the keystrokes"

BDD - Behavioural Driven Development

Given context

When event occurs

Then outcome

DDD - Domain Driven Design

CDD - Contract Driven Development

Making the sausage

Intresting walkthrough on the work of BDD-framework in Clojure. BDD and Clojure is interesting in itself, but also interesting how they worked out their ideas.

NoSQL

ACID doesn't scale out. Problems:

• Data size
• Connectivity
• Semi structure (modeling and sparse data)

4 types of new types

• Key value
• Big table
• Document
• GraphDB

DYNAMO-paper by amazon very influential.

BASE

• Basically Available
• Soft state
• Eventually consistent

Examples:

• Voldemort - key-value store
• Cassandra - BigTable
• Google Bigtable
• Apache Hadoop HBase - Bigtable
• Couch DB - Document (REST)
• Mongo DB - Document
• RIAK - Document (REST with DYNAMO scaleout)
• Neo4j - Graph
• Allegiograph - Graph

Acceleration

clcl Clipboard enhancement

mousefeed Eclipse-plugin to help learn keyboard shortcuts

Focus

Flow takes 20-30 minutes to reestablish.

TweakUI To turn off windows balloon tips

jedi concentrate Screen dimmer

Turn off notifications like email, phone, etc

Office "quiet time" for example 9-11, 13-15.

Google desktop to find things efficiently, plugin for indexing any filetype.
