Skimmers Guide for Week 15 of Functional Programming for the Object-Oriented Programmer

21 Jul

“…today’s commonplaces of object-oriented programming were mysterious and brain-bending twenty or thirty years ago… Monads and other higher-higher-higher-order abstractions may follow the same trajectory. I hope they do.

What did we read about?

This was our fifteenth week of ‘Functional Programming for the Object-Oriented Programmer‘ by Brian Manick.

We start from Page 141 at section 10.10 Lifting Functions with Monads, finishing at Page 146 at the end of chapter 10!

Only 6 pages to read this week but they are absolutely rammed packed with information and examples.

What stood out?

  • Page 142 – The m-lift monad is introduced which is a concise way to do short-circuiting.
  • Page 144 – The sequence-m monad is introduced as a way of transparently doing looping.

If you read nothing else this week…

  • Page 146 – 10.13 Choose your own adventure – A succinct summary of monads, which bestow upon programmers both great power and great responsibility ;)

Skimmers Guide for Week 14 of Functional Programming for the Object-Oriented Programme

21 Jul

“…functional programming terminology is perhaps slightly less than optimal for novice understanding. That is the case with monad terminology.”

What did we read about?

This was our fourteenth week of ‘Functional Programming for the Object-Oriented Programmer‘ by Brian Manick.

We start from Page 132 at the start of section 10.6 Monads as Data-Driven Extended Continuation-Passing Style. Finish at Page 141 at the end of section 10.9 Exercises

We continue looking at monads and delve into them further. We work on a simplified version of the truth and gradually form a concrete appreciation of the complexity and power of monads!

What stood out?

  • Page 139 – 10.8 Cond is all about “a multi-way” if, appearing much like a switch statement.
  • The exercise at the end of our reading is amusing and gives us our first chance in writing our own monad!

If you read nothing else this week…

  • Page 133 – “The lie” gives you a working understanding of monads, which is absolutely critical.

Skimmers Guide for Week 13 of Functional Programming for the Object-Oriented Programme

8 Jul

“A monad is a collection of functions that can be used to modify stepwise calculations.”

What did we read about?

This was our thirteenth week of ‘Functional Programming for the Object-Oriented Programmer‘ by Brian Manick.

We start from Page 121 “10 Branching and Looping in Dataflow Style” and read all the way through to Page 131 stopping at “10.5 Extending continuation-passing style”.

Going over the “->” and “let” functions again, we compare the linear/non-linear calculation of them both. We look at removing explicit branching through “monads”, which allow us to insert code after the computation steps in the normal flow of our code.

Finally we are introduced to the “continuation-passing style”, revolving around the idea of “flowing the result” of each step of our computation into the next. There are some Exercises to get you to grips with it and then we elaborate on how the style gets evaluated.

What stood out?

  • “10.1 That pesky nil again” (Page 124) – A well worked example of doing nil checking automagically via the “with-monad” and “domonad”.
  • “10.2 Continuation-passing style” (Page 126) – An interesting use of the “->” function which actually makes computation steps clearer.

If you read nothing else this week…

  • Practice the continuation-passing style in Exercises 1 – 3 (Page 127).
  • “10.4 Expansions in Evaluation” (Page 128) gets under the covers of continuation-passing style and how it gets evaluated. We compare this to how the “domonad” gets evaluated and how understanding both is critical to understanding how monads in general work.

Skimmers Guide for Week 12 of Functional Programming for the Object-Oriented Programme

29 Jun

“With loosely-coupled objects that communicate only by passing behaviors (functions) around (rather than entire bundles of state and behavior in the form of objects), the early part of design may become easier.

What did we read about?

This was our twelfth week of ‘Functional Programming for the Object-Oriented Programmer‘ by Brian Manick.

We begin on Page 115 at the start of section 9.4, picking up the exercises from last week’s reading. We finish at Page 120 at the end of chapter 9.

The exercises revolve around putting into practice what we have learnt about “Point-Free Programming”. We are introduced to the new juxt function before being tasked with a diverse set of exercises to test understanding on various topics so far.

Finally we look at higher order functions from the perspective of object orientated programming and how we can decouple our design using “function passing” (either directly in Ruby or via single abstract method interfaces in Java).

What stood out?

  • Exercise 2 introduces the neat little function juxt, definitely a good tool to know about and not a bad exercise either.

If you read nothing else this week…

  • Exercise 7 – 10 are brilliant practice of the Clojure we have learnt so far. Highly recommend everyone gives it a try as they are great for working on your code style and thinking about reducing duplication.
  • “9.5 Higher-order functions from the object-oriented perspective” – only two pages but makes you think about how you should handle your dependencies (on functions or on objects).

Skimmers Guide for Week 11 of Functional Programming for the Object-Oriented Programme

20 Jun

Skimmers Guide for Week 11 of Functional Programming for the Object-Oriented Programme

8JUN

“A function that can close over external values is called a closure. I mention that because now you know why Clojure is called ‘Clojure’.  It’s a portmanteau word combining ‘closure’ and ‘Java’.

Higher Order FunctionsWhat did we read about?

This was our eleventh week of ‘Functional Programming for the Object-Oriented Programmer‘ by Brian Manick.

We began on Page 108, at the start of chapter 9 “Functions That Make Functions”. We read through to Page 114, leaving the exercises for next week.

We learn all about closures, and the important role they play in functional programming.  First of all we looked at how repetition can be avoided by creating a partial function, and the Clojure partial function.

We then read about lifting functions to a higher order.  Higher order functions are functions that act on other functions rather than plain values.

Then we looked at point free, or parameter-free, functions and took the Clojure comp function as an example.

To finish there was  a mild rant about style, looking at the different stylistic choices that are available.

What stood out?

  • This week we started to look at what really makes Functional programming different.  You may be familiar with the idea of a factory method creating objects, but functional programming takes it to a whole other level.  Personally I found it necessary to keep rereading paragraphs while I tried to understand what the author was trying to tell me.  Hopefully next weeks exercises will help to complete my understanding.
  • We also caught glimpses of the concepts that underpin functional programming.  The author makes light of the strange expressions in little asides like “No doubt the term ‘closing’ seemed perfectly apt to someone somewhere” and “no doubt the analogy of formal parameters to geometrical points seemed perfectly apt to someone somewhere.”  Personally I’d like to know more about the thinking behind these names.
  • The mild rant on style is revealing.  In Java we are used to having conventions that are followed by everybody so that there is a consistant style.  In Clojure there are so many ways of doing something it is no wonder that functional code can be so incomprehensible.

If you read nothing else this week…

  • If you already understand higher order functions then you can skip this week.  You may find the mild rant on style interesting.
  • If you are new to functional programming then you have to read all of it.  There are a lot of big concepts being introduced.

The Web Keeps Spinning

It Just Won’t Stop Spinning

 

Web created by a spider exposed to caffeine

Next year the world wide web will be a quarter of a century old.  Since it’s birth at CERN back in 1989 it hasn’t stopped moving, changing, evolving or revolving.  From clunky desktops in labs to the phone in your pocket change has been the only constant.  This month we are looking at books that can help us get to grips with the web’s latest developments.

Scala Out Back

Scala promises to improve productivity by providing us with a rich, expressive language with strong domain specific support.  Frameworks are being built to deliver on that promise.

Learning Play! Framework 2

by Andy Petrella

The Play framework promises to make it faster and easier to build web applications that scale reliably while supporting both web and mobile clients.

Akka Essentials

by Munish K. Gupta

Akka is a toolkit and runtime for building highly concurrent, distributed, and fault tolerant event-driven applications on the JVM.

HTML5 Up Front

HTML5 Enterprise Application Development

by Nehal Shah, Gabriel José Balda Ortíz

HTML5 has been a trending topic for a long time, but the lack of Flash support on iOS devices has sped up its penetration. New features in HTML5 come at a time when web developers are pushing the limits of what is achievable and HTML5, CSS3, and JavaScript have become an important alternative for building rich user interfaces.

HTML5 Canvas Cookbook

by Eric Rowell

The HTML5 canvas is revolutionizing graphics and visualizations on the Web. Powered by JavaScript, the HTML5 Canvas API enables web developers to create visualizations and animations right in the browser without Flash. Although the HTML5 Canvas is quickly becoming the standard for online graphics and interactivity, many developers fail to exercise all of the features that this powerful technology has to offer.

Getting the User Experience Right

Selenium Testing Tools Cookbook

by Unmesh Gundecha

Selenium automates browsers. That’s it. What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.

Responsive Web Design by Example

by Thoriq Firdaus

Responsive web design is an explosive area of growth in modern web development due to the huge volume of different device sizes and resolutions that are now commercially available. You can now create your very own responsive website quickly and efficiently, allowing you to showcase your content in a format that will work on any device with an Internet browser.

Skimmers Guide for Week 10 of Functional Programming for the Object-Oriented Programmer

10 Jun

“…I think you could say “There is a thing that we’re justified in saying is an object-oriented architectural style.” We’re not at that point for the functional style yet, so far as I can tell.

What did we read about?

Our tenth week of ‘Functional Programming for the Object-Oriented Programmer‘ by Brian Manick.

We pick up on a new chapter on Page 99, “8 Embedding Functional Code in an OO Codebase”. No exercises this week and we blitz through until the end of the chapter on Page 107.

To be honest, a lot of this chapter is irrelevant or uninteresting, revolving around boilerplate code or SQL. Skimming/skipping through is recommended!

What stood out?

  • Concept of “functional nuggets” in OO code, Page 100. An interesting theory, sadly demonstrated in a rather tedious fashion.

If you read nothing else this week…

  • The big picture, Page 108.  Talking about the evolution of functional programming and looking forward to “Functional Patterns for Enterprise Application Architecture.”
