Rails 3 Error Installing mysql2 gem

2011-06-22T23:14:00.000-07:00

When trying to install mysql2 gem for Rails 3, issuing "bundle install" command

gives me following error "Error installing mysql2: ERROR: Failed to build gem native extension."

The following line should solve the issue:

sudo apt-get install libmysql-ruby libmysqlclient-dev

I Have Fallen In Love

2009-08-02T21:59:00.000-07:00

I Have Fallen In Love (with the same woman three times)
by Jose Mari Chan
poem written by Ninoy Aquino while in prison for Cory on there 19th wedding anniversary

I have fallen in love
With the same woman three times
In a day spanning nineteen years
Of tearful joys and joyful tears.
I loved her first when she was young
Enchanting and vibrant, eternally new
She was brilliant, fragrant and cool as the morning dew
I fell in love with her the second time
When first she bore her child and mine
She’s always by my side, the source of my strength
Helping to turn the tide…
I fell in love again with the same woman the third time
Looming from the battle her courage will never fade.
Amidst the hardships she has remained
Undaunted and unafraid
She is calm and composed. She is God’s lovely maid.

[TS] Thinking Sphinx

2009-03-24T19:01:00.000-07:00

Using Thinking Sphinx in your rails app?
This is how I install TS in my Ubuntu machine.

First you need to install sphinx (if you haven't already).

$ curl -O http://sphinxsearch.com/downloads/sphinx-0.9.8-rc2.tar.gz
$ tar zxvf sphinx-0.9.8-rc2.tar.gz
$ cd sphinx-0.9.8-rc2
$ ./configure
$ make
$ sudo make install


Then install Thinking Sphinx as a plugin in your rails app.
I'm running on edge so:

script/plugin install git://github.com/freelancing-god/thinking-sphinx.git

Add these to your models.

define_index do
...
...
...
...
end

To index your models run:
$ rake thinking_sphinx:index or rake ts:in

To start searching daemon:
$ rake thinking_sphinx:start

To stop
$ rake thinking_sphinx:stop

To test:
Model.search "test"

After Girl Geek Dinner

After Girl Geek Dinner #1 | TechTicks

Cebu Girl Geek Dinner

2008-11-28T04:33:00.000-08:00

A colleague of mine invited me to attend the first Cebu Geek Dinner (actually first in Asia) and Web2.0 Social Media Meetup.
I'm always interested in social networking stuffs and it is right here in the office so hey why not?

Ms. Carmen Villadar from Frankfurt Girk Geek Dinners and her friends online (Cora, Paul & others) made the meetup possible, sponsored by Exist Global.

I don't really know that is was a girl geek meeting, all I know is it's a Social Media Meetup but hey the talk with the girls and the geek boys was sure fun and worth your time. The discussion revolves on technologies, web2.0, social networking, current events and even social awareness. Talking while munching a monster pizza! I'd also met new friends from other I.T. companies and others that I already knew. All of us got a chance to stand in front and talk about what stuffs we do and how come we are in the I.T industry and lots of stuffs. Tell you, mine wasn't easy, am not used to talking in front of people (am used to just sit everyday lol) but they are very friendly. :)

You maybe asking if its exclusively for the girls? No, of course not, boys can come too as long as they bring a geek girl with them. :)

The question brought up by digitalfemme that stick to my mind among other things is: How would you use technology to bring change?
If I'll ask you the same question what would you say?

Error when opening pgAdmin in Ubuntu?

2008-11-17T19:30:00.000-08:00

Got these following errors when you run pgAdmin in Ubuntu?

ERROR : can't open file '/usr/share/mime-info/air.mime' (error 2: No such file or directory)

ERROR : can't open file '/usr/share/mime-info/air.keys' (error 2: No such file or directory)

Installing Git in Ubuntu

2008-10-21T23:39:00.000-07:00

"git" can mean anything
"global information tracker": you're in a good mood, and it actually
works for you.
"goddamn idiotic truckload of sh*t": when it breaks

Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.

Git is an Open Source project covered by the GNU General Public License.
It was originally written by Linus Torvalds with help of hackers.

Steps:
1. $ sudo apt-get install libexpat1-dev zlibc curl
2. $ cd ~ && mkdir src && cd src
3. Get the latest version or choose any version here: http://www.kernel.org/pub/software/scm/git/
~/src$ wget http://www.kernel.org/pub/software/scm/git/git-1.6.0.tar.gz
4. ~/src$ tar -xvf git-1.6.0.tar.gz && cd git-1.6.0
5. ~/src/git-1.6.0$ ./configure
6. ~/src/git-1.6.0$ make
7. ~/src/git-1.6.0$ sudo make install
8. ~/src/git-1.6.0$ git --version
git version 1.6.0
Your done!

Exist Goes Indoor Wall Climbing

2008-07-27T20:41:00.002-07:00

Exist Global goes to sports for the month of June and July and last weekend June 05, 2008 Exist folks leave their laptops to go wall climbing!
Most of us, including me were first time climbers but of course some are already mountain climbers like Emman.

Our instructor made a quick run through on the basics of wall climbing since we haven't a little bit of idea on it.
First, he showed us the *harness and the step by step process of wearing it to protect us while we are climbing.
Then, what to observe while climbing like the rope should be in front between our shoulders and not at the back or at the side of the body so may not get hurt in case we fall.
And when going down you can let go and free fall and let the *belay take your load down, securing your feet on the wall to prevent bumping.
You can be a *belayer too while you are not climbing or be a photographer hehehe.

*Harness - a support consisting of an arrangement of straps for holding something to the body (especially one supporting a person suspended
*Belay - a rope management technique used to ensure that a fall taken by a climber can be quickly arrested; belay techniques are also used for additional safety/control in rappelling, raising and lowering systems, and for mountain stream crossings.
*Belayer - the person paying out or taking in the rope for a climber.

A little stretching and now we are ready to climb. Better say it with pictures!

Deploying Rails Application in Morph AppSpace

2008-07-27T20:41:00.000-07:00

Deploy your Rails applications in a fault-tolerant environment

with load balancers, private database, backups, and monitoring
— instantly expandable on the fly in case you get slashdotted.

Deploying your Rails application to a Morph AppSpace is a snap.
You create an account and then download a pre-configured Capistrano
recipe. Make a quick update of your SVN location and run the CAP command.
That’s it. Within a few minutes, your application is up and running,
ready for the world. (taken from Mor.ph)

I know you are quite familiar with Morph AppSpace
and this is just a quick simple steps on how to do deploy
your rails application in Morph.

Assumptions:

1. Your are using Subversion in your Rails application,
if not refer to this post.

2. You need to have an existing Morph Account, if none
you can sign-up for free here.

3. You have already installed Capistrano.

4. Deploying should be done in Linux environment (currently)

*Updated: I first tried deploying the application using Windows but it had errors during deployment. Since I had Linux and the deployment in Linux is pretty sweet with no errors at all, that's why I assumed it won't work for Windows.

But hey am wrong hehehe :) you need to tweak things in Windows (as usual) to make it work.

Steps:

1. Go to Morph Panel and create a new subscription

2. Click "Create Data Base". This will create an initial database setup
for your application.

3. Click "Download CAP File". This is the pre-configured Capistrano recipe
that Morph created for deploying your rails application.

4. Update the CAP(Capistrano) file, by setting your repository location.
e.g.
set :repository, nil => set :repository, 'http://svn.exist.com/svn/railsapp/trunk'

5. Run the CAP file.
>> cap -f morph_deploy.rb morph:deploy

a. This will get the application's code in svn.
b. If prompted for Morph Authentication, enter your Morph username/password.
c. Then this will upload the code in a S3.
d. If message is "Code upload is Done", your application is now ready for the world.

You can access it using the domain you specified in your subscription.
e.g http://your_apps_domain.morphexchange.com/
Your rails application is now available 24/7 via Morph AppSpace!

Our RoR App Deployed in Morph AppSpace

2008-07-27T20:40:00.001-07:00

After almost a month of learning the curves of Ruby Language and Rails Framework

we successfully deployed our application in Morph AppSpace
here's our RoR App available 24/7: Coders'Block Application
Thanks to Morph!

About Coders'Block:
Lets developers paste their code online and share files to everyone. Codes Posted has Syntax Highlighter which depends on the programming language written. This is useful for when the developer needs help in debugging his code. Other developers can give their comments and suggestions on the posted items too!

Creators:
Diana, Gwen, and Gretchen

*Feel free to share you suggestions, we know it needs more tweaking hehehe it's a 5days work application so bear with us.

RestFul Authentication

2008-07-27T20:40:00.000-07:00

I am an RoR noob myself and having different Rails plugins at my fingertips proves to be helpful.
If you want to add an authentication in your RoR application you can use Restful Authentication. Without you doing the code for logging feature so you have ample time for main features in your application.

Steps:
1. In your app root dir:
>>ruby script/plugin install http://svn.techno-weenie.net/projects/plugins/restful_authentication

2. Then generate authenticated files:
>> ruby script/generate Authenticated Sessions User
( or if you want to activation add: --include-activation )

3. Edit the migration file if you want to add/remove fields and do the migration:
>> rake db:migrate

Viola! You have the logging feature added.
You can further update the models and add activation and an signup emailer if you want to. :)

On thoughts... bits and pieces: Adding Captcha to your Application

2008-07-27T20:39:00.001-07:00

Are you developing an RoR application and want to add CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) Authentication in it?

*Note
1. simple_captcha plugin is being used here if you want to use other plugin, you can find it in the net.
2. You must have RMagick installed. (This is a prerequisite.)

Here's the simple steps in adding a captcha image:

1. Type this command in your app root dir:
>> ruby script/plugin install svn://rubyforge.org/var/svn/expressica/plugins/simple_captcha

2. After successful installation.

>> rake simple_captcha:setup

(Am using Rails 2.x version for <>

>> rake simple_captcha:setup_old)

3. Then do the migration.

>> rake db:migrate

4. Add this line of code to you config/routes.rb

map.simple_captcha '/simple_captcha/:action', :controller => 'simple_captcha'

5. Add this line in the file app/controllers/application.rb

include SimpleCaptcha::ControllerHelpers

6. In your view add:

<%= show_simple_captcha(:object=>"user") %>

7. In your model add:
apply_simple_captcha

8. Validating with captcha:
@user.valid_with_captcha?

First Day High!

2008-07-27T20:39:00.000-07:00

hehehe it should have been RoR first day!
yep, April 25 or simply put today was the first day
of the RoR training.

Ms Mafe (blooming in her white attire) opened the training
with the trainee's RoR training expectations (taken from the survey) and there are lots of them,
(take note it's an intensive training so better fasten your seat belt!)
and of course there are managament's expectations too.

Then Ms. Jackie gives us the training schedule, topics
to be discussed, and the RoR gurus that would share their knowledge throughout the training.

Finally Stephen (a.k.a Popol, formal mode ) takes the stage.
He is our first instructor for Ruby Basics and that would be Ruby Background.

He give us a brief history on how Ruby was conceived in the world.

Tiny bits of Ruby history:
Created by Yukihiro Matsumoto(Matz)
1993, February 24: Matz started to work on Ruby.
1995, December: First release 0.95.
1996, December: 1.0 is released.
2003, August 4: 1.8.0 is released.
1.9.0/ December 26, 2007 (2007-12-26)
Influenced by: Smalltalk, Perl, Lisp, Scheme, Python, CLU, Eiffel, Ada, Dylan
The Semantics and Features of Ruby:
Ruby is object oriented - every data type is an object (classes and types which other languages designate as primitives).
It has support for introspection, reflection and metaprogramming, as well as interpreter-based threads,
dynamic typing, and parametric polymorphism.

The Ruby Philosophies:
(Stephen said this can guide you if Ruby is meant for you in the long run.)
productive and fun
simple and friendly API
consistent and regular
principle of least surprise
we are the masters, they are the slaves (for the time being)
Less is more
The ruby way

* Ruby is designed for programmer productivity and fun,
following the principles of good user interface design.
The systems design needs to emphasize human, rather
than computer needs.
*It follows the principle of least surprise (POLS),
meaning that the language should behave in such a way
as to minimize confusion for experienced users.

As Stephen discusses these things in reality there are things
that are going on in the background.
(I know what your thinking but it isn't what I mean.)
We (the trainees) are actually setting up the environment needed.
Good thing I have everything set up but unfortunately I have to change my Rails
version to a lower version. :(

After losing connection from time to time, I guess almost everyone
had installed Ruby, Rails, and Aptana as our IDE (this am not sure).

Yeah, their are questions and Stephen answered everything quite well.
He also showed us some simple tricks, that is changing the state of an object.
Since in Ruby each objects knows its own state.
So if you know you know your state you can play around with it right?
I somewhat got interested with "final" objects that are supposed to be
final but still Ruby can get his hands on. lol Yes, Stephen clarifies that
Ruby has a power to freeze and unfreeze (final) objects!

The more interesting part is metaprogramming.
Metaprogramming is writing programs that write programs.
Analogy: "Writing Ruby that can write Ruby."
A question that is left unanswered:
Does Java had metaprogramming?

That's all for 0.5 day! Maybe I'd miss some important things so kindly share it, you are very much appreciated.

Learning a new language

2008-07-27T20:38:00.001-07:00
Learning a new language.
(A new language for me to learn but is in the industry for a long time.)
Yeah, I'll definitely going to learn a new language.
I've been with Java since my college years and it's my favorite language since.
There is something similar to it and they are born at the same time or
more accurately Ruby is a wee bit older.
They say Ruby is sleek, beautiful/sexy, hehehe it's easy and fun!
A language that is more developer friendly.
The codes are pretty readable even for a newbie like me. :)
Ruby on Rails will be my girlfriend for now.
Yes, Ruby on Rails.
Using Rails framework (for web apps)
and Ruby language. ;)
Hope we will have fun together as I get to know her better. :D
