Technology Trends

What is the market?

Is there a reason to change?

Are the barriers to exit high?

Mainframe

A mainframe has one of the worst price/performance ratios of any product or technology in any industry.

Slam dunk to replace mainframes with faster, smaller,

cheaper servers?

COBOL (circa 1959)

55 Years

COBOL is not modern

80% of daily business transactions are still processed in COBOL * IT Modernization: The Changing COBOL Market Could Affect Your Decision – Gartner Group, 8 August 2008

One in four universities teach COBOL

* Bridging the COBOL skills gap – Micro Focus, 2013

1980: It was the ONLY choice

170 billion lines of code

* IT Modernization: The Changing COBOL Market Could Affect Your Decision – Gartner Group, 8 August 2008

That’s a lot of bitcoins….

And they just keep going

The Risk Of Failure Is High

31% of projects are cancelled before completed53% of projects will cost 189% of their original costs* Choas Report – Standish Group

Businesses will rely on COBOL for another

ten to twenty years*

* Bridging the COBOL skills gap – Micro Focus, 2013

Enterprise Applications

High barriers to exit

Blackberry

A once thriving company

Suddenly looked like this…..

No longer just a business device

Ubiquitous device

Everybody has one

I don’t need multiple phones!

We replace our phones every two years

Soon everyone was using something else

Mobile Devices

Low barriers to exit

Notes will soon turn 25

1989 - 2014

What does the future hold?

Notes Mail

Current messaging

File store

30-day transition period

Messaging

Low barriers to exit

Notes Applications

Domino Designer on every desk

Easy to learn and deploy

Handle any problem

The most successful SMA platform ever!

• 50,000 companies• 200 applications (avg)• 10 million applications

Apple’s app store reached 1 million applications in October 2013

And the code….

5,000 lines per application x10 million applications =50 billion lines of code

Cost200 applications x$20,000 per application =$4 million investment

10 million applications x$20,000 per application =$200 billion investment

Time

IBM XPages:200 applications x5 weeks per application = 20 years

i.e. Team of 4 developers 5 years

Time

Platform migration:200 applications x3 months per application = 50 years

i.e. Large team of consultants forever

SMAs

High barriers to exit

Implications

Notes applications are NOT going away!

Think 10+ years

Business needs are not frozen

The expectation gap Is growing

Adding modern features deliversadditional business value

Notes is web 2.0

Notes is mobile

It’s a different language!

No, this is a different language

This is not a different language

Dim db as NotesDatabaseSet db = session.Getdatabase(“server”, “file”)

Database db = session.getDatabase(“server”, “file”);

Classes: How do they work?

You already knowSet s = New NotesSession()Set item = doc.Replaceitemvalue(“foo”, “bar”)doc.Replaceitemvalue(“Readers”, “Nathan T Freeman”).readers=true

But I like procedures!

Fine, stick with them‘ScriptLibrary libs.atFormulas

Public Function atRightBack(stringToSearch As String, subString As String) As String

End Function

Use “atFormulas”

//Java class libs.atFormulas

public static String rightBack(String stringToSearch, String subString ) {

}

import static libs.atFormulas;

I tried Java before…

Java is different now

Why bother?• Cheaper to maintain• Fewer bugs• Runs faster• Easier to hire• Better guidance• Portable skills• Millions of open source and commercial

libraries

Future ProofingLotusScriptTim

Presented By Devin Olson, Czarnowski

LotusScript is the past

20 years old (almost to the day)Only 2 key changes to the language itself:- Booleans Convenience functionsEverything else has been API enhancements

The future is XPages

JavaJavascript

Subconscious preparation

Apply 4 optional changes to how you write LotusScript

Backwards compatible to R4 Training yourself for free and without even

realizing it Runtime execution and ongoing maintenance

will be either Identical or Better

Case matters

Learn to love “camel case” The LotusScript editor is wrong

Autocompletes to proper case database.Gettitle() should be database.getTitle() document.Getitemvalue() should be document.getItemValue()

Lower camel is the convention for nearly every language in common use For method names (e.g. identifyUser() ) Class names should still be upper camel (e.g. Database,

DocumentCollection)

Case matters

If becomes if For becomes for While becomes while ...you’re probably seeing a pattern here Because these are all one word, the lower camel is indistinguishable from lowercase

( )

Parentheses matter

Optional in several portions of LotusScript syntax Mandatory in each equivalent in Java and JavaScript

Functions:o Somemethodnameo someMethodName()

Conditionals:o if somethingistrue theno if (somethingIsTrue) then

If it doesn’t make the code harder to read, add parentheses

In Java, you can tell Designer to remove any parentheses you don’t need

Document fields are method parameters

Stop using:doc.SubjectStart using: doc.getItemValue(“subject”)doc.replaceItemValue(“subject”,“Hello world!”)

Write your own classes LotusScript has always had classes (yes, since R4) Most LotusScript developers only write top-level

functions If you’ve ever written code that uses NotesSession,

NotesDatabase, etc., you’re already using classes, you just might not be writing your own

Classes simplify variable management Classes maximize code reusability Classes help our code to stop thinking in “documents”

and start thinking in business processes, and the people, places, and things that interact with and are impacted by those processes

Write your own classes Don’t use the Property Get / Property Set pattern Define private properties, expose each via “getters” and

“setters” If it’s a Boolean, use isPropertyName() instead of

getPropertyName()

Private firstName As String Public Function getFirstName() getFirstName = firstNameEnd Function Public Function setFirstName(firstName byVal As String) Me.firstName = firstNameEnd Function

Write your own classes

THIS IS THE SINGLE MOST IMPORTANT THING YOU CAN DO TO EASE YOUR TRANSITION TO XPAGES OR SHAREPOINT OR NATIVE MOBILE DEVELOPMENT OR PRETTY MUCH ANY DEVELOPMENT PLATFORM THAT CURRENTLY EXISTS OR IS LIKELY TO EMERGE IN THE FORESEEABLE FUTURE OH MY GOD I SIMPLY CANNOT STRESS THIS ENOUGH JUST DO IT!

What language is this?

if (workflow.isComplete()) { doc.replaceItemValue(“status”, “Approved”); }

Okay, fine, there’s one other difference

LotusScriptDim doc As NotesDocumentSet doc = database.getDocumentByID(“OU812”)

JavaScriptvar doc = database.getDocumentByID(“OU812”);

JavaDocument doc = database.getDocumentByID(“OU812”);

If you adopt these habits now…

Learning JavaScript or Java is mostly about remembering two things: 1. where to use curly

braces2. where to use

semicolons

Yes, I’m serious!
