Finally publishing my first book - Full Stack for linux Framework

After months of  delaying the date of publishing, I finally pressed the publish button.

Well, at first it was a mistake, ... and I still want to write more about it.

It is only 45% complete at the current time. But once done, I thought that i would help me by giving me pressure to write more.


 The book here in Lean Pub: Full-Stack-for-Ruby-Framework

https://leanpub.com/Full-stack-for-Ruby-Framework

I want to help other developers like me to use Ruby, Ruby-On-Rails Stack and not be afraid of some devops duties.

So in my book I trying to give you a good perspective of what it is to be a Full Stack developer, with a lot of practical examples.

Mainly for Ubuntu server, this can also be applied to Debian, RedHat , Centos and other flavours of Linux.

I using Mac for local development and therefore thinking to write more about it.

But  I am also waiting from readers feedback to guide me on what to write next.

As today I sold my 1st version, I say thank you to my first reader, and be patient as I will also give  more and more book update along the way.

The advantage with Lean Pub is that I can start publishing the book as I write it for a small fee.

And the advantage of the first readers is that they would get the next updates for free.

Full Stack for ruby Framework

For the few people following the old RailsBuntu

Note that The book has now changed its name to:
 "Full stack for Ruby Framework"

I started to write this book few years ago, and at the time I was mainly concentrating on Ubuntu. But other times I worked over different flavours of Linux. Therefore the content of the book is not any more specific to Ubuntu but to all Linuxes.

It is also hard to find time to focus on writing so the first is still not ready, but moving towards its goal.

Spread The word for the Hackerjobs.co.uk

When doing contracting it seems very difficult to find jobs without the helps of the recruitment agencies . Sadly for us and our potential employers they eat a portion of our hard labour. For some agencies it can be well deserved, but one thing that I think a bit excessive is that if they send our CV to one company with some kind of exclusive right on our behalf for up  1or 2 years.
Although this agreement is between the agencies and our potential employer, this can sometimes play against us.

One way to change this, would be to go through site like HackerJobs but the problem with this is that not a lot of people knows it, and therefore some employers may say that it doesn't bring good  selection of candidate. Probably due to the fact that the site is still not well known?
So let s spread the word ... It may set us free...

Create Rails 4 application and use RVM

First, although I already blog few year ago about installing RVM, my blog needs to be updated with latest RVM set-up. The new command lines for the installation of RVM (tested on Ubuntu 13.10):

sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev
curl -L https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
echo "source ~/.rvm/scripts/rvm" >> ~/.bashrc

Install ruby and gems 

rvm install 2.1.0
rvm use  --default 2.1.0
ruby -v

note the path of ruby and the associated gemset
.rvm/gems/ruby-2.1.0@global
This would be useful later on to know which rvm ruby "ruby-2.1.0" and rvm gemset "global" we are using so we can load them automatically every time we access the project directory.

 rvm list
rvm rubies

ree-1.8.7-2011.03 [ i686 ]
ruby-1.9.2-p320 [ i686 ]
ruby-1.9.3-p484 [ i686 ]


ruby-2.0.0-p353 [ i686 ]



 => ruby-2.1.0 [ i686 ]
# => - current
# =* - current && default
#  * - default

then add  rails gems and create new application called "jobsearch"

 rvm gemset list

 echo "gem: --no-ri --no-rdoc" > ~/.gemrc
 gem install rails 
 rails new jobsearch cd jobsearch
 bundle

Note: the --no-rdoc and the --no-ri will save you time especially on production server where the documentation is not really require.

Create the rvmrc file so that your directory switch automatically to the right ruby and gemset

 rvm --create --rvmrc ruby-2.1.0@global

The file .rvmrc is created and now every time that you go to the project directory of your application the right ruby and gems are loaded

$ cd ..
$ cd jobsearch/

You are using '.rvmrc', it requires trusting, it is slower and it is not compatible with other ruby managers,
you can switch to '.ruby-version' using 'rvm rvmrc to [.]ruby-version'
or ignore this warning with 'rvm rvmrc warning ignore /home/user/dev/jobsearch/.rvmrc',
'.rvmrc' will continue to be the default project file in RVM 1 and RVM 2,
to ignore the warning for all files run 'rvm rvmrc warning ignore all.rvmrcs'.

Add this line in the end of .rvmrc to display the selected gem

if $- == *i* # check for interactive shells
then

The Benefit of RVM

RVM is a great tool when you want to test different rubies or if you have several applications on a single server, as you can use any combination of rubies and gemsets all on a single machine without any problem.
