Two books

A member of a mailing list I’m on recently asked: what two books should be on every engineer’s bookshelf? Here’s my answer.

Many software engineers, the ones described toward the end of Code Complete 2, would benefit most from Donald Knuth’s The Art of Computer Programming and Computers and Typesetting. It is truly astounding that one man has contributed so comprehensively to the art of variable-height monitor configurations.

If, to misquote Bill Hicks, “you’ve got yourself a reader”, then my picks are coloured by the fact that I’ve been trying to rehabilitate Object-Oriented Design for the last few years, by re-introducing a couple of concepts that got put aside over the recent decades:

  1. Object orientation; and
  2. Design.

With that in mind, my two recommendations are the early material from that field that I think shows the biggest divergence in thinking. Readers should be asking themselves “are these two authors really writing about the same topic?”, “where is the user of the software system in this book?”, “who are the users of the software system in this book?”, and “do I really need to choose one or other of these models, why not both or bits of both?”

  1. “Object-Oriented Programming: an evolutionary approach” by Brad Cox (there is another edition with Andrew Novobilski as a co-author). Cox’s model is the npm/CPAN model: programmers make objects (“software ICs”), describe their characteristics in a data sheet, and publish them in a catalogue. Integrators choose likely-looking objects from the catalogue and assemble an application out of them.

  2. “Object-Oriented Software Construction” by Bertrand Meyer. Meyer’s model is the “software engineering” model: work out what the system should do, partition that into “classes” based on where the data should naturally live, and design and build those classes. In designing the classes, pay particular attention to the expectations governing how they communicate: the ma as Alan Kay called the gaps between the objects.

Ultimate Programmer Super Stack: Last day!

I already wrote about the Ultimate Programmer Super Stack, a huge bundle of books and courses on a range of technologies: Python, JS, Ruby, Java, HTML, node, Aurelia… and APPropriate Behaviour, my book on everything that goes into being a programmer that isn’t programming.

Today is the last day of the bundle. Check it out here, it won’t be available for long.

Ultimate Programmer Super Stack

There’s a great bundle of polyglot learning taking place over at the Ultimate Programmer Super Stack. My book, APPropriate Behaviour – the things every programmer needs to know that aren’t programming – is featured alongside content on Python, Ruby, Java, JS, Aurelia, Node, startups, and more.

The bundle is just up for a week, but please do check it out: for not much more than you’d probably pay for APPropriate Behaviour you’ll get a whole heap of stuff that should keep you entertained for a while :).

OOP the Easy Way: now 100% complete

Hello readers, part 3, the final part of the “OOP the Easy Way” journey, has now been published at Leanpub! Thanks for joining me along the way! As ever, corrections, questions, and comments are welcome (you can comment here if you like), and as ever, readers who buy the book now will receive free updates for the lifetime of the book. While there’s nothing new to add, this means that corrections and expansions will be free to all readers.

If you enjoy OOP the Easy Way or found it informative (or maybe even both), please recommend it to your friends, colleagues and followers. It’d be great if they could enjoy it, be informed by it, or both, too!

On Sharecropping

Today I came across the site Danny Reviews, at which fellow internet Danny Yu has posted over 1400 book reviews. I realised that if I had posted book reviews of every book I have read since I became an internet, I would have more than 900 reviews online, maybe over 1000. How do I know? Because my GoodReads profile lists those 900 books.

Now actually GoodReads are quite generous in their terms: I own all of the information I’ve posted there, and I can export all my books, including my reviews such as they are. But that’s entirely up to GoodReads, they decided to be nice and provide an export feature. Other sites take their digital sharecropping more seriously.

I got lucky, but we should all think carefully about what we’re posting to where.

Book update: OOP the Easy Way

Obejct-Oriented Programming the Easy Way gets ever closer, as the first part (of three) is now substantively complete. If you have been holding off from buying the book, now would be a great opportunity to jump in, as a whole part of the book’s argument is now laid out. As ever, your feedback is welcome, and readers who buy now will get free updates throughout the development of the book.

OOP the Easy Way

It’s still very much a work in progress, but OOP the Easy Way is now available to purchase from Leanpub (a free sample is also available from the book’s Leanpub page). Following the theme of my conference talks and blog posts over the last few years, OOP the Easy Way starts with an Antithesis, examining the accidental complexity that has been accumulating under the banner of Object-Oriented Programming for nearly four decades. This will be followed by a Thesis, constructing a model of software objects from the essential core, then a Synthesis, investigating problems that remain unsolved and directions that remain unexplored.

At this early stage, your feedback on the book is very much welcome and will help yourself and fellow readers to get more from the book. You will automatically get updates for free as they are published through Leanpub.

I hope you enjoy OOP the Easy Way!

Recommend me some books or articles

I’ve been looking for something to read on these topics, can you help?

  • a history of the Unix wars (the ‘workstation’ period involving Sun, HP, Apollo, DEC, IBM, NeXT and SGI primarily, but really everything starting from AT&T up to Linux and OS X would be interesting)
  • a business case study on Apple’s turnaround 1997-2001. I’ve read plenty of 1990s case studies explaining why they’ll fail, and 2010s interpretations of why they’re dominant, and Gil Amelio’s “On the Firing Line” which explains his view of how he stemmed the bleeding, but would like to fill in the gaps: particularly the changes from Dec 1997 to the iPod.
  • a technical book on Mach (it doesn’t need to still be in print, I’ll try to track it down): I’ve read the source code for xnu, GNU Mach and mkLinux, Tevanien’s papers, and the Mac OS X Internals book, but could still do with more

On books

I’d say that if there’s one easy way to summarise how I work, it’s as an information focus. I’m not great at following a solution all the way to the bitter end so you should never let me be a programmer (ahem): when all that’s left is the second 90% of the effort in fixing the bugs, tidying up edge cases and iterating on the interaction, I’m already bored and looking for the next thing. Where I’m good is where there’s a big problem to solve, and I can draw analogies with things I’ve seen before and come up with the “maybe we should try this” suggestions.

Part of the input for that is the experience of working in lots of different contexts, and studying for a few different subjects. A lot of it comes from reading: my goodreads account lists 870 books and audiobooks that I’ve read and I know it to be an incomplete record. Here are a few that I think have been particularly helpful (professionally speaking, anyway).

  • Douglas Adams, The Hitch-Hikers’ Guide to the Galaxy. Adams is someone who reminds us not to take the trappings of society too seriously, and to question whether what we’re doing is really necessary. Are digital watches really a neat idea? Also an honourable mention to the Dirk Gently novels for introducing the fundamental interconnectedness of all things.
  • Steve Jackson and Ian Livingstone, The Warlock of Firetop Mountain. I can think of at least three software projects that I’ve been able to implement and describe as analogies to the choose your own adventure style of book.
  • David Allen, Getting Things Done, because quite often it feels like there’s too much to do.
  • Douglas Hofstadter, Godel, Escher, Bach: An Eternal Golden Braid is a book about looking for the patterns and connections in things.
  • Victor Papanek, Design for the Real World, for reminding us of the people who are going to have to put up with the consequences of the things we create.
  • Donald Broadbent, Perception and Communication, for being the first person to systematically explore that topic.
  • Steven Hawking, A Brief History of Time, showing us how to make complex topics accessible.
  • Roger Penrose, The Road to Reality, showing us how to make complex topics comprehensively presentable.
  • Douglas Coupland, Microserfs, for poking fun at things I took seriously.
  • Janet Abbate, Recoding Gender, because computering is more accessible to me than to others for no good reason.
  • Joshua Bloch, Effective Java, Second Edition, for showing that part of the inaccessibility is a house of cards of unsuitable models with complex workarounds, and that programmers are people who delight in knowing, not addressing, the workarounds.
  • Michael Feathers, Working Effectively with Legacy Code, the one book every programmer should read.
  • Steve Krug, Don’t make me think!, a book about the necessity of removing exploration and uncertainty from computer interaction.
  • Seymour Papert, Mindstorms, a book about the necessity of introducing exploration and uncertainty into computer interaction.
  • Richard Stallman, Free as in Freedom 2.0, for suggesting that we should let other people choose between ther previous two options.
  • Brad Cox, Object-Oriented Programming: An Evolutionary Approach, for succinctly and effortlessly explaining objects a whole decade before everybody else got confused by whether a dog is an animal or a square is a rectangle.
  • Gregor Kiczales, Jim des Rivieres, and Daniel G. Bobrow, The Art of the Metaobject Protocol showed me that OOP is just one way to do OOP, and that functional programming is the same thing.
  • Simson Garfinkel and Michael Mahoney, NEXTSTEP Programming: Step One was where I learnt to create software more worthwhile than a page of BASIC instructions.
  • Gil Amelio, On the Firing Line: My 500 Days at Apple shows that the successful business wouldn’t be here if someone hadn’t managed the unsuccessful business first.

There were probably others.
