THE ANATOMY OF A SERIOUSLY SOPHISTICATED AIR APPLICATION

BEFORE WE GET DOWN TO BUSINESS…

WHAT WAS OUR BRIEF FROM FIAT? BUILD A PRODUCT THAT HELPS IMPROVE YOUR DRIVING USING TELEMATIC DATA COLLECTED FROM THE CAR

WHY IS ECO:DRIVE “SOPHISTICATED”? THE CHALLENGES CONNECTING YOUR CAR TO YOUR COMPUTER IS A NEW CONCEPT TO MOST DRIVING DATA CAN BE CONFUSING LARGE AMOUNTS OF DATA, ONCE PER SECOND OF EVERY JOURNEY

WHY IS ECO:DRIVE “SOPHISTICATED”? THE CHALLENGES CONNECTING YOUR CAR TO YOUR COMPUTER IS A NEW CONCEPT TO MOST DRIVING DATA CAN BE CONFUSING LARGE AMOUNTS OF DATA, ONCE PER SECOND OF EVERY JOURNEY YET THE SOLUTION HAD TO BE INTUITIVE EASY TO USE RESPONSIVE

A LITTLE BIT MORE DETAIL… BUILT USING ADOBE AIR 1.1 AND FLEX

A LITTLE BIT MORE DETAIL… BUILT IN 4 MONTHS BY A DEVELOPMENT TEAM OF 5 BUILT USING ADOBE AIR 1.1 AND FLEX

A LITTLE BIT MORE DETAIL… BUILT IN 4 MONTHS BY A DEVELOPMENT TEAM OF 5 CREATED USING FLEXBUILDER 3 PROFESSIONAL EDITION BUILT USING ADOBE AIR 1.1 AND FLEX

A LITTLE BIT MORE DETAIL… BUILT IN 4 MONTHS BY A DEVELOPMENT TEAM OF 5 CREATED USING FLEXBUILDER 3 PROFESSIONAL EDITION LAUNCHED IN 3 LANGUAGES, SOON TO BE 5 BUILT USING ADOBE AIR 1.1 AND FLEX

DELVING DEEPER IMPORTING DATA GRAPHING THE DATA CONTEXTUALISING THE DATA

IMPORTING DATA: PARSING LIMITED SPACE AVAILABLE IN BLUE & ME COMPUTER MORE COMPUTING POWER AVAILABLE ON THE DESKTOP THAN IN THE CAR EASE OF PARSING WAS NOT THE FIRST PRIORITY NO BITARRAY IN ACTIONSCRIPT 3 DATA IS STORED IN A TIGHTLY PACKED BIT ARRAY

IMPORTING DATA: WRITING DATA TO THE DATABASE THERE WERE TWO MAJOR REQUIREMENTS IMPORT HAD TO BE HIGHLY PERFORMANT USER INTERFACE HAD TO REMAIN SMOOTH AND RESPONSIVE

IMPORTING DATA: WRITING DATA TO THE DATABASE THERE WERE TWO MAJOR REQUIREMENTS IMPORT HAD TO BE HIGHLY PERFORMANT USER INTERFACE HAD TO REMAIN SMOOTH AND RESPONSIVE THERE WERE TWO PROBLEMS USING A TIMER WAS NOT FAST ENOUGH USING “FOR” LOOPS MEANT AN UNRESPONSIVE APPLICATION

IMPORTING DATA: WRITING DATA TO THE DATABASE THERE WERE TWO MAJOR REQUIREMENTS IMPORT HAD TO BE HIGHLY PERFORMANT USER INTERFACE HAD TO REMAIN SMOOTH AND RESPONSIVE THERE WERE TWO PROBLEMS USING A TIMER WAS NOT FAST ENOUGH USING “FOR” LOOPS MEANT AN UNRESPONSIVE APPLICATION THE SOLUTION? THE “ASYNC CHUNKER MONKEY”

IMPORTING DATA: THE ASYNC CHUNKER WHAT? USING SYNCHRONOUS “FOR” LOOP TO PROCESS EACH ITEM IN AN ARRAY

IMPORTING DATA: THE ASYNC CHUNKER WHAT? USING A TIMER USING SYNCHRONOUS “FOR” LOOP TO PROCESS EACH ITEM IN AN ARRAY

IMPORTING DATA: THE ASYNC CHUNKER WHAT? USING THE ASYNC CHUNKER MONKEY USING SYNCHRONOUS “FOR” LOOP TO PROCESS EACH ITEM IN AN ARRAY

IMPORTING DATA: THE ASYNC CHUNKER WHAT? MAX TIME FOR EXECUITION IS SET BY DEVELOPER USING THE ASYNC CHUNKER MONKEY USING SYNCHRONOUS “FOR” LOOP TO PROCESS EACH ITEM IN AN ARRAY

THE MOST TRICKY PART…

KEEPING QUALITY HIGH

KEEPING QUALITY HIGH PROOF OF CONCEPTS CONTINUOUS INTEGRATION USING CRUISECONTROL.NET PEER REVIEW ON EVERY CHECK-IN UNIT TESTS USING FLEXUNIT AND FLEXCOVER

TOP TIPS AND LESSONS LEARNED

TOP TIPS AND LESSONS LEARNED FILE.GETROOTDIRECTORIES ISN’T AS GREAT AS YOU MIGHT THINK NEVER WRITE DATA TO THE APPLICATION DIRECTORY MULTI-LINGUAL? ALWAYS GET THE USER TO CHOOSE THEIR OWN LANGUAGE USE THE VIEWSTACK CLASS CAREFULLY KEEP YOUR DATABASE ACCESS STRATEGY CONSISTENT

CLOSING WORDS

CLOSING WORDS… DO PROOF OF CONCEPTS FOR ANY RISKY AND ESSENTIAL FUNCTIONALITY UNIT TEST YOUR CODE. IT HELPS PREVENT BUGS AND IMPROVES THE APPLICATION ARCHITECTURE. THINK ABOUT PERFORMANCE – ESPECIALLY IF YOU ARE PROCESSING LARGE AMOUNTS OF DATA ADOBE AIR IS A GREAT PLATFORM FOR INNOVATIVE DESKTOP APPLICATIONS.
