RRRR!

Rest, don't push it, listen to your body... I was getting that advice from nearly everyone, runners, shop keepers and even a physiotherapist who had suffered shin splints. I had been feeling increasing pains in both my inner lower shin and outer shin lately and felt my legs were heavy and tired all the time. I was really spooked by my possible 'anterior compartment syndrome' and even more by the possible 'tibia stress fracture'. So I took a whole week off, no running.

Ruby provided a way to keep my mind at least a bit focused on running after that. I made a beginning to write an application that can read my exercise data from my Nike+ipod. The app is not finished yet, only the parser part is. I still need to finish the part that gets the data from the database and shows you some nice trends. I'll put the code on github when I have that part running.

Reading 'Ruby in Practice', which I've won, gave me inspiration for my app. However, I did not even finish the first chapter or two other books were in my mailbox! Off course I started to read those, 'The Manga Guide To Databases' and 'Grey Hat Python' as well. To add to the book frenzy, I just found out I also won the ebook version of the ultimate Ruby bible: 'Programming Ruby 1.9: The Pragmatic Programmers' Guide'! So yeah, get ready for some reviews ;-)



Running put the great week to a fantastic end. I have been feeling a bit jumpy the whole week, I really missed the running already. I guess it's quite addictive. Anyway, I did some googling and asked a physiotherapist I know about some stretch exercises for my shins. Yesterday I found the following stretches and they had an immediate effect:




Seated shin stretch
More shin stretches
'Swan lake stretch'

That last one did it for me so I decided to call it the 'swan lake'...

Ok...after that I decided to wear my new black-tech-ninja long-sleeve running shirt and go at it. This time however I really took time to do a proper warm-up. First a fast paced 1k walk, after that a 1k run. After that some stretches. Then I went off, I felt the inner shin hurting again quite soon. But then I saw a horse track, a sand path. When I went running on that, I felt nothing. The rest of the run was mostly a struggle because I had not ran for a whole week and was eating pizza and other badness while doing my geek things. However, when I got home I was pleasantly surprised by my stats: I passed 4K, nearly got to 5, RRRR!!

Review: Learn to program 2nd edition

As I'm taking a brake from running to prevent shin injuries. So I had time to finish reading my latest book, 'Learn to program 2nd edition'. Well I've finished it and thought I'd share my feelings about it in a review, so here it is:



The best book out there if you want to learn programming. If you have a little experience but are unsure, you will like this book too.

The book is also suited as a lightweight introduction to Ruby. But if you have a decent amount of experience in another programming language and want to learn Ruby, or if you want to dive in directly, consider a book like Programming Ruby or the Ruby Way.

The book is very readable and funny. You'll understand most things without too much effort because of the way the author explains things clearly.

The book contains fun exercises such as the 'angry boss' or 'deaf grandma' exercises.

The only minor points were that the exercises were mostly not very practical for real life situations. The last few chapters were not as clear in explaining things as most of the book.

This book offers great value for money and is well worth your time, adding to that it's not a big book and very reasonably priced. Definitely worth it.

Since the second edition is really just from the press, there are no other reviews. So you'll just have to do with mine (I'm a critic so don't worry!):

Books anyone?

Like many geeks, I have a book addiction. If I'm near a bookstore I start to feel the need to go inside and check out their collection on the various subjects that interest me, or might interest me in the future. And if I'm online and bored, I just might surf some bookstores or publisher websites.

I'm not so picky in my buying, but I am in my reading. Sometimes a book just proves it's not worth the time, a pity but there's always other interesting stuff out there. So save your time, put it on the shelf and start to read something hopefully better. Oh, and try to read some reviews before you buy (note to self).

Today I posted a few book reviews on RubyLearning.org's book promo forums. I thought I'd share them on my blog as well. Also, I have finished reading my 'Start to Run' book. In the sense of sound mind, sound body there's a short review on that as well.

Don't forget to check out RubyLearning, you can learn Ruby for free! Oh, and yeah, you can now even win a copy of popular books :-)

As I'm writing this, the shipping of 'learn to program, 2nd edition' was announced in my mailbox. Yummie, new book!


Learning Ruby by Michael Fitzgerald, O'Reilly publishing.
This was my very first introduction in Ruby. After Having seen a friend build a Rails website in a few minutes I was impressed and wanted to know about Ruby.
The bookstore had two books on ruby, this one and the other being the massive pickaxe. I chose this book since I was not prepared to read such a huge book. I just wanted a brief into to see what it was all about.

Learning Ruby
The book starts with the basics and a quick tour of Ruby. After the first two chapters you start to have a rough idea about what Ruby is and what it's for. After the two introductory chapters, the usual language basics follow. Conditional loops, strings, math, arrays, hashes, working with files and classes are all dealt with. After that one chapter deals with various things such as processing XML, reflection, metaprogramming, RDoc and embedded ruby. The last chapter is a brief intro on Rails.

Conclusion
The title of the book was a poor choice. It should have been something like 'introducing ruby' for example. The best feature of this book was its shortness and simplicity, while still giving a good introduction to the world of Ruby. What I missed were some short introductions on things such as TDD, Merb, Sinatra, Shoes etc. After reading this book you won't have the feeling you have 'learned' Ruby. You have a good picture of what it is and what it can do. You know a bit of the syntax and how to use irb and check out documentation. You also know about a few extra things such as RDoc and Rails. The book is well written and I had no problems running the code for all except a Tk example. It's a nice book for the absolute beginners in programming, but I think there are better suited books for the absolute beginners out there. Instead, people who have a bit of experience in other programming languages, and just want to know what all the fuss is about will enjoy this book. This book is not for those that really want to learn about the language and it's inner workings and reasoning behind it.

Ruby Cookbook by Lucas Carlson & Leonard Richardson, O'Reilly publishing.

I bought this book on a shopping spree. Just needed a 3rd book to add to my shopping basket for a '3 = 2' promotion, it had good reviews so I bought it.

Ruby Cookbook
This book is not a straightforward learning book. It contains just a whole lot of 'recipes', small solutions for common problems. This book is not meant to be read in your bed from beginning to end. Rather it's something to grab on to when you want to do something but don't know how. Each chapter deals with a certain topic such as system administration, GUI's, multitasking, testing, webservices, Rake, databases, Internet services, Rails, metaprogramming and a whole lot of more basic language recipe's such as matching strings with regular expressions or comparing floating point numbers. It's a big fat book with nearly 900 pages.

Conclusion
Well, this is somewhat difficult as it's not a book to read from beginning to end. When I used the book, I have always found the solution for my problem in no time. It just covers a whole lot things. The recipes are short and clear and contain references for further information. It's a really good book and writing this review I am actually surprised I have used it so little times. Since it's such a big book, and not something to read in one piece, It's easy to put on your shelf, forget about it and use Google for help, like I did. The fact is however, that in all cases I thought about the book, it provided the answer I needed.

Given that, this book's pretty efficient. It saves a lot of time providing solutions and you don't even have to read the whole thing. Personally I think this book comes not to it's right on the bookshelf, but more as a desktop companion. Consider a digital version to keep around anr CRTL-F when in need.

Practical Ruby Gems by David Berube, Apress publishing.

I stumbled on this book on an Internet auction site. Not having any clue about what rubygems were I thought the 10,- euro price would pay itself back. Read on to see my thoughts about the book...


Practical Ruby Gems
This book contains three parts:

Part 1 deals with what gems are, how to install them and do version control.
Part 2, the biggest part of the book, contains chapters that deal with different Gems. All of them contain a description and one or two practical examples on how to use the Gems to get something done. All code is explained after that. The book focuses mostly on Gems that can be used in a web development or sysadmin context.
Part 3 is about creating and distributing Gems yourself.

I think the book is a nice read for starters who finished reading their first Ruby book and now want to create something useful. But I think it can be informative for more expierenced Rubyists as well. It's pretty well written but I found that a few code listings contain flaws. This is mostly because the Gems used have been renamed, made obsolete by different gems or had other adjustments. So it's mostly due to the books age (April 2007) and some specifics of my operating system (Ubuntu). The publisher has not posted any errata and the downloadable code is flawed as well (at least on my system). This was a bit disappointing, but my opinion is that it's still a valuable book that will save you time in the long run. I bought the book second hand for 10 euro's so I'm pretty positive about purchasing it. But I think I would not spend the full price on the new book, but rather wait a possibly second edition or a good discount offer.

Start to Run by Evy Gruyaert, Lannoo publishing.

I bought this book to serve as a companion for the fantastic 'start to run' podcast. My main reason was to have some more background info on the do's and dont's in running.

Start to Run
First things first, this book is only available in Dutch/Flemmish language as far as I'm aware of.
The book is about 158 pages and is built up around 4 different themes being: Running expierences, Running tips, stretch and yoga exercises and food tips and recipes. Four experts provided the content for these themes: an expierenced ports coach, a fysiotherapist with an expertise in revalidation, a chef and a runner.

Conclusion
I liked the book. I enjoyed the motivating writeups from evy. I think having the running schedules on print is pretty handy, so now I can easily lookup what my next running session will look like. The stretching exercises are very good. I don't think yoga can be learned from just a few pictures however, but I don't really care about yoga. If you do, check out wii sports or buy a dvd or go to a club or something. There are plenty of good tips for starters in this book, one thing I learned which is a recurring message is to take it easy. But I did not like the recipes. Though food is something really personal and you might like them. I expected some more practical meals for some reason. Many recipe's look a bit too complicated for somebody who just had an exercise. Also, many of the ingredients are not available in the average supermarket.

Overall I recommend the book if you just started to run. It might also be a good present.
