Mount a key on a Lenovo keyboard

J June, 2010 /

It was really tricky. To get the key out I have to pull it stright away with one screwdriver. But when I have to mount it back – it was nightmare!!!!

Those keyboards are getting really challenge. I can’t imagine how a kid will repair his keyboard in 2019 year.

So….The for me it was really easy if because I have found this post here.

  1. find a way to lock your screen
  2. mount the parts on the keyboard! not on the key
  3. Make sure that the little part of the deck-chair is mounted on first on the bottom parts of the laptop keyboard
    1. slide it from top to bottom to hold it firmly
  4. The big part of the deck-chair will lie on top of the laptop keyboard mount. Then with shrink it a little so that it falls in the holes bellow
  5. Next the put the key ontop of the already mounted deck-chair. but not exactly on top but a little bellow the middle point in a way that you can slip to down and above. This way the key will get mounted on the deck-chair (lower part). Next press it down to stick firmly the top part of the deck-chair.

Here is the picture of the Lenovo Y510.

Auch – PHP

J May, 2010 /

WTF?!

PHP use one standard but those Symfony guys use another?!

You may wonder why the helpers are named according to the underscore syntax rather than the camelCase convention, used everywhere else in symfony. This is because helpers are functions, and all the core PHP functions use the underscore syntax convention.

Argh…this rmagick gem – aways difficult to install/maintain.

J May, 2010 /

I have recently upgraded to Ubuntu 10.04 and I got this nasty rmagick gem error:

RMagick2.so: This installation of RMagick was configured with ImageMagick 6.5.5 but ImageMagick 6.5.7-8 is in use. (RuntimeError)

google for This installation of RMagick was configured with ImageMagick 6.5.5 but ImageMagick 6.5.7-8 is in use. (RuntimeError)

then found this page in mixed English/Chinees

and finally got a page in German :)

Then I decide to write this post in English and slightly modify the solution

instead of putting

RMAGICK_BYPASS_VERSION_TEST = true in the deploy.rb

I have put this in the development.rb

and all it works – this way on the production I will be forced to use real compatible library or at least check again for another solution or gem.

AUCH! This solution doesn’t work even in development I got weird core dumps :( …so here it is another try

Here is the real working  solution:

su -
git clone http://github.com/rmagick/rmagick.git
cd rmagick/
ruby setup.rb
ruby setup.rb  install

How to turn your free client to a payed one

J April, 2010 /

Very good examples of phrases like

  • ‘If you’d like me to do that for you, I charge $XXX/hour.’
  • ‘I can spend ten minutes with you, and if you require more assistance I will be glad to schedule a consultation at my regular rates.’
  • ‘You do know that we just crossed into paid time?’ he asked. ‘Oh, yes,’ the prospect said

Nice code

J April, 2010 /

I have just finished one method and I was not happy with the code. Then I put a comment on top of the method “Far from perfect….”.

Then I read the class – it was ugly.

here is the before

def validate
 return if is_email == false
 found = InternetComunicatorType.find(:first, :conditions => {
 :is_email => true,
 })

 return unless found

 if found.id != id
 errors.add(:is_email, "We have already email type")
 return
 end
end

here is the after

def validate
  if is_email
    found = InternetComunicatorType.find(:first, :conditions => {
      :is_email => true,
    })

    if found and found.id != id
      errors.add(:is_email, "We have already email type")
    end
  end
end

The result is much far readable

Mongoid presentations

J April, 2010 /

When starting with mongoid I have missed a lot some demo source code.

How it works with controllers, does it plays nice with nested attributes, such things.

Here is presentation of mongo  and here are some slides

Mongoid

J April, 2010 /

I writing this post for those who start using Mongo in their rails applications. I want to share my experience. First I discovered mongoid but then i saw mongo_mapper  – so I decide to go with the crowd. But! I was wrong. I there is no documentation for mongo_mapper but some blog posts arround, the examples are not aways working and you have to fight with all the code – I don’t maybe I have found some old documentation. When you dive in the code – again no documentation and not clear behaviour. Maybe it is a good solution but for me it doesn’t work. I lost 1.5 days experimenting and hoping that the things will go.

Then I give a try with mongoid. It has wonderfull documentation for starters also it seems at first glance that the code in mongoid is more readably and human friendly. It took me 2hours to port all my models to mongoid.

The guy developing mongoid seems pretty active.

last words – it is pleasure to work with mongoid – I recommend it to all.
