For those interested in the contents of the book. If you are looking for a better (read total) understanding of the Ruby object model, interested in Eigenclasses and all sorts of advanced programming techniques, grab a copy! I think it is a great read!

Last week I found myself writing a method ending with a question mark, but it wasn’t returning a Boolean. Just as most of the other methods ending with a question mark I wrote the last couple of years it returns either a NilClass instance, which evaluates to false, or some other object instance, which evaluates to true.

The question I want to answer is if such a method should return true or false or is returning nil or some object good enough?

Personally I think it should return a boolean value. I have more arguments opposed to returning a bool than not, but it just feels right, seems more logical. But! if there are humongous performance implications, I’m also happy enough with the way I did it before.

To check just this I wrote a simple class and some benchmarking code to see how big the implications are.  I have two methods which mimics the normal situation and a method which returns a boolean value. I’m using the ‘!!’ trick to accomplish the typecasting. [you can see all the code in my ruby study git repos]

The test results show, I’m running the code 1 million times, that the difference is marginal. So for me the only logical conclusion is that returning a boolean, which feels more logical to me, is perfectly acceptable and will be my weapon of choice starting as of right now. If you have a practical use to actually justify this, please let me know!

So to take the bull by the horns I’ve declared Tuesday evening as my “learning evening”, Wednesday as my “blogging evening” and Thursday as my “pet project evening”.

To keep up in my line of work it is necessary to be informed, almost constantly, about the latest developments. To do this well I really need several hours of dedicated reading and practicing (Tuesday). Because I believe that writing about what I learn makes the info more stickier and raises my own understanding, also I might even end up helping other people (Wednesday). I also want some reserved time to work on personal projects and implement what I’ve learned and maybe written about in my pet projects (Thursday)

What do you do to make sure that you keep up and how do you make sure that you spent enough time at it. Enlighten me

Right now,  I guess cause I write a bit in advance, she just started with book 4. I’m also trying to get here started in some other series I really like, but she wants to stick to one series at a time. I myself don’t really mind reading in several series at once. I must admit I do prefer series over a single book.

These are the series I’m currently busy with:

• The wheel of time by Robert Jordan (just finished book 12)
• The Sword of Thruth series by Terry Goodkind (just finished book 6)
• A Song of Ice and Fire by George r.r. Martin (Waiting for book 5 too frickin long!!)
• The Three Worlds Cycle by Ian Irvin (Busy in book 3)
• The Elves by Bernard Hennen ( Recently finished the first book, only available in German and Dutch right now)
• The Dwarfs by Markuz Heitz ( Finished book 2 quite a long time ago , think the first book is also available in English)

There is more, I’ve read two series from Tad Williams and the first three series from Robin Hobb (stopped in book two of the fourth, too depressing!) Two questions. One: Do you read simultaneously? and Two: Which series do I absolutely have to read (and why)?

Looking forward to your suggestions!

It is a short but comprehensive guide into the world of HTML5. If you haven’t,  like me, took the time yet to dive into HTML5. This is definitely a great start and a must read.

For those who are already experimenting with HTML5 and regularly visit the W3C or WHATWG sites. I guess that there are probably no surprises in this one for you.

What I really like about the book is that it is a very quick read, about 2 hours, but also has a very high information density. If this tickled your curiosity, please visit the ‘A Book Apart‘ site

Big chance you are suffering from ‘The Curse of Knowledge’

knowledge from ‘Made to Stick’ by Dan & Chip Heath

I haven’t read anything yet, but I didn’t want to keep this to myself

Happy reading!

There are a lot of sites around the web dedicated to help people like me create a good/better blog. Some that seem useful at first sight are http://www.dailyblogtips.com/, http://www.toptenblogtips.com/ and http://www.problogger.net. At first sight, because obviously I have to try things out and see if they work. One of the things I can’t find, but probably read somewhere in the past, is ‘Have some posts on the shelves’.

By doing this I give myself some more time to review my articles more thoroughly, but the most important reason is that this helps when I might have a writers block for a few days. If I create an article buffer for myself I think this prevents virtual deadline stress So above all this is something I’m going to stick to and when you are reading this I am probably busy with writing or checking an article you can read somewhere in the near future.

Oh… and just in case you are wondering, I’m not planning to become a pro blogger! I like my current work too much for that, but it never hurts to read some professional tips.

Starting today I’m going to give it another try. Why? Basically the 37Signals book ‘Rework’ motivated me to do so and I strongly believe that I will learn more when I write about it. Will people be interested? I don’t know, I’ll see. The least I will get out of it, is learn more and that alone is worth the effort.

I’ve recently bought several books, Rework, Made to Stick, The Tipping point, Delivering Happiness, Metaprogramming Ruby and also a bunch of fantasy books. I’ll start with writing about what I read, so I have to rethink what I’ve read more thoroughly. From time to time I might write about the things I experience in day to day life. I can’t guarantee if I will keep writing this time, but I’ll definitely put in my best to make it work this time!

Hope to see you around.

Best,
Jeroen
