2013 Microsoft® MVP Award! in Visual C#

A couple of month’s back I’ve got an email from Microsoft that I have been nominated for a MVP award, the only thing I should do was to fill out a word document. First I thought it was a spam mail and reread the mail. When I was sure it wasn’t spam I filled out the document, and then forgot all about it.

Then a few days ago I’ve got an email “Congratulations 2013 Microsoft MVP!”

I couldn’t believe it! And I still really can’t!.. But my MVP award should arrive on Monday, and when I have the award in my hand I’m sure that I believe it :o)

Today, there are more than 4,000 MVPs worldwide. They represent more than 90 countries, speak over 40 languages, answer more than 10 million questions a year, and are awarded in almost 90 Microsoft technologies.

And I must thanks for those that have nominated me and how proud I am to be a MVP.

Brewing beer Kata 1st. draft

I am giving a 15min. lightning talk at @brewww "TypeScript kata: The TDD style" Friday 22. of marts.

And thougt I would make a brewing beer kata to the talk, though I'm not sure the following kata is good enough as a standard Kata, please give comment to improvements. Ill promise to post the final Kata in TypeScript later :-)

First draft of the kata:

1. Create a simple Brewary with a method IBeer Brew()
1. The method take 0 parameters but needs to return an IBeer
2. The Beer should be of type lager
2. Allow the Brew method to handle a brewingTemperature and a fermentationInDays argument
1. If brewingTemperature is less than 5 throw exception “Temperature is to low”
2. If brewingTemperature is greater than 4 and less than 11 return a beer of type lager
3. If fermentationInDays is less than 7 and greater than 14 throw exception “fermentation for lager beers should be between 7 and 14 days”
3. Add optional ingredients of type string as “roasted malt” and “barley” to make a stout
1. If fermentationInDays less than 5 and greater than 6 throw exception “fermentation for stouts beers should be 5 or 6 days”
2. brewingTemperature not equal 20 throw exception
3. Expect result to be of type Stout
4. Expect beers alcohol to be 7percent if fermentationInDays is 5
5. Expect beers alcohol to be 8percent if fermentationInDays is 6

Declaration source files and google analytics

What is Declaration source files?

Declaration source files are restricted to contain declarations only. Declaration source files can be used to declare the static type information associated with existing JavaScript and expose their behavior.

I have started to implement TypeScript in my projects at work :-)

In that case I had to implement google analytics but ran into the problem, that I did not have intellisence for the that.

I googled a bit and could not find any declaration file for that, so I made my own.
I can now acces ga, _gaq, _gat and the Tracker object with intellicense in my TypeScript file, nice...

Example

describe("tester Google Analytics Code  _gaq object", () => {
    it("can create _push", () => {
        _gaq.push(['_setAccount', 'UA-XXXXXXX-YY']);
        _gaq.push(['_gat._anonymizeIp']);
        _gaq.push(['_trackPageview']);

        _gaq.push(() => {
                var tracker = _gat._getTrackerByName('UA-65432-1');
                tracker._trackPageview();
            }
        );
    });  
});

I have pushed it to https://github.com/borisyankov/DefinitelyTyped but until it is merged you can get the files here https://github.com/RonnieHegelund/DefinitelyTyped/tree/master/google.analytics

TeaCrunch - CodeCoverage for Typescript

When working in .NET and writing unit test, I really like the green dots NCrunch gives me. I think its a great way to show what code you have test coverage on.

I would love to have this in TypeScript to, but haven't found any, so I have started making a prove of concept my self.

The prove of concept works, but is very unstable and have to rewrite the code, and need to find out how I can read the results from the test explorer. The biggest problem is to find the time to rewrite my code :-)

TypeScript - The rest parameter

Rest parameter in TypeScript has nothing todo with REST (REpresentational State Transfer)

If you are familiar with C# params keyword, The rest parameter is the same. The rest parameter lets you specify a function parameter that takes an argument where the number of arguments is variable.

An example could be a function that make a Sum of a variable length of numbers:

Sum(1,2,3,4);

C# example

public int Sum(params int[] list)
{
  int sum = 0;
  foreach (int i in list)
    sum += i;
  return sum;
}

TypeScript example

public Sum(...list Number[]) : number
{
    return list.reduce( 
        (a,b) => { a + b }
    );
}

And the result when compiled to JavaScript

function sum() {
    var numbers = [];
    for (var _i = 0; _i < (arguments.length - 0); _i++) {
        numbers[_i] = arguments[_i + 0];
    }
    return numbers.reduce(function (a, b) {
        return a + b;
    });
}

Enterpise development in TypeScript

I have started writing a book” Enterprise development in TypeScript”

I am an agile developer, so this book will be published Early and Published Often. This way I can get feedback from readers and make the book as good as possibly.

The focus of this book is to use TypeScript in your enterprise applications. The book will go through the basics of TypeScript, different tools and frameworks, how to create unit tests and, then automate your tests, builds and deployment. The book is far from done, and if you think the book is missing something please don’t hesitate to contact me.

Please, tweet and show your support by saying what you'd like to pay for it at https://leanpub.com/enterprise-development-in-typescript
