F# presentation – part 1

I would like to thank everyone that attended the yesterday’s online session about F#.

Please join me again on Thursday for the second part of the introduction to F# where we will talk about asynchronous and parallel programming and unit testing.

Below, you can find the slides of yesterday’s session.

F# book

I just found out a new book which can be browsed online:

http://ctocorner.com/fsharp/book/

I think it represents a great starting point for learning F# as it covers very well the main features of the language.

Enjoy,

Bogdan

Learning resources for F#

As I’ve said, F# is currently one of my main interest points so I thought about sharing some resources I found very useful.

Let the |> fun begin (F#)

At Ecole Polytechnique we had a lot of classes in OCaml (operating systems, compilers etc.) and things were really easy and fun.

In the past 6-7 years, Microsoft Research has prepared F# (http://research.microsoft.com/en-us/um/cambridge/projects/fsharp/) with OCaml at its core and I thought it is worth giving it a try.

Things went great and I actually used F# to implement a financial algorithm for a large set of data (hundreds of millions of records).  As F# is a compiled language that benefits from all of the functional programming features and from the interoperability with other .NET languages (C#, VB), I think using it in some scenarios could represent a great benefit.

In the next period I will have more posts about F# as it currently represents one of my main interests.

On the 22nd and 25th of February I will have two online sessions for Microsoft Romania (http://www.microsoft.com/romania/evenimente/) talking about the main features of F#.

Stay tuned for more!

AJAX and PHP – Building Modern Web Applications – 2nd Edition

Lately I’ve been busy finishing the second edition of my AJAX and PHP book: AJAX and PHP – Building modern web applications.

AJAX and PHP - Building modern web applications - 2nd edition

Overall, I think this edition adds new value having a focus on Object Oriented Javascript including JQuery. Patterns also play an important role and have their own chapter.
