rails generate controller UsersController

and seen your app folder filled with useless files?

create app/controllers/users_controller_controller.rb
invoke erb
create app/views/users_controller
invoke test_unit
create test/functional/users_controller_controller_test.rb
invoke helper
create app/helpers/users_controller_helper.rb
invoke test_unit
create test/unit/helpers/users_controller_helper_test.rb
invoke assets
create app/assets/javascripts/users_controller.js.coffee
invoke scss
create app/assets/stylesheets/users_controller.css.scss

Eww, that’s gross.
To undo that rails generate, simply run:

rails destroy controller UserController

and rails will destroy all those ugly files for you!

remove app/controllers/users_controller_controller.rb
invoke erb
remove app/views/users_controller
invoke test_unit
remove test/functional/users_controller_controller_test.rb
invoke helper
remove app/helpers/users_controller_helper.rb
invoke test_unit
remove test/unit/helpers/users_controller_helper_test.rb
invoke assets
remove app/assets/javascripts/users_controller.js.coffee
invoke scss

String.instance_eval { def foo; p "bar"; end }
String.foo = "bar"

String.class_eval { def foo; p "bar"; end }
"sausage".foo = "bar"

So, using instance_eval adds a class method.
On the other hand, using class_eval adds a instance method.

Why?

class_eval is a method of the Module class, meaning that the receiver will be a module or a class. The block you pass to class_eval is evaluated in the context of that class. Defining a method with the standard def keyword within a class defines an instance method, and that’s exactly what happens here.

instance_eval, on the other hand, is a method of the Object class, meaning that the receiver will be an object. The block you pass to instance_eval is evaluated in the context of that object. That means that String.instance_eval is evaluated in the context of the String object. Remember that a class name is simply a constant which points to an instance of the class Class. Because of this fact, defining a method in the context of Class instance referenced by String creates a class method for the String class.

The simplest rule of thumb is that you should set up a has_many :through relationship if you need to work with the relationship model as an independent entity. If you don’t need to do anything with the relationship model, it may be simpler to set up a has_and_belongs_to_many relationship (though you’ll need to remember to create the joining table in the database).

Roger Waters – The bravery of being out of range

You have a natural tendency
To squeeze off a shot
You’re good fun at parties
You wear the right masks
You’re old but you still
Like a laugh in the locker room
You can’t abide change
You’re at home on the range

You opened your suitcase
Behind the old workings
To show off the magnum
You deafened the canyon
A comfort a friend
Only upstaged in the end
By the Uzi machine gun

Does the recoil remind you
Remind you of sex
Old man what the hell you gonna kill next
Old timer who you gonna kill next

I looked over Jordan and what did I see
Saw a U.S. Marine in a pile of debris
I swam in your pools
And lay under your palm trees
I looked in the eyes of the Indian
Who lay on the Federal Building steps

And through the range finder over the hill
I saw the front line boys popping their pills
Sick of the mess they find
On their desert stage
And the bravery of being out of range
Yeah the question is vexed

Old man what the hell you gonna kill next
Old timer who you gonna kill next

Hey bartender over here
Two more shots
And two more beers
Sir turn up the TV sound
The war has started on the ground

Just love those laser guided bombs
They’re really great
For righting wrongs
You hit the target
And win the game
From bars 3,000 miles away
3,000 miles away

We play the game
With the bravery of being out of range

We zap and maim
With the bravery of being out of range

We strafe the train
With the bravery of being out of range

We gain terrain
With the bravery of being out of range
With the bravery of being out of range

We play the game
With the bravery of being out of range

Nothing is original. Steal from anywhere that resonates with inspiration or fuels your imagination. Devour old films, new films, music, books, paintings, photographs, poems, dreams, random conversations, architecture, bridges, street signs, trees, clouds, bodies of water, light and shadows. Select only things to steal from that speak directly to your soul. If you do this, your work (and theft) will be authentic. Authenticity is invaluable; originality is non-existent. And don’t bother concealing your thievery – celebrate it if you feel like it. In any case, always remember what Jean-Luc Godard said: “It’s not where you take things from – it’s where you take them to.

Unnatural Selection

They’ll laugh as they watch us fall
The lucky don’t care at all
No chance for fate
It’s unnatural selection
I want the truth

I am hungry for some unrest
I want to push this beyond a peaceful protest
I wanna speak in a language that they’ll understand

Dedication, to a new age
Is this the end of destruction and rampage?
Another chance to erase then repeat it again

Counter balance this commotion
We’re not droplets in the ocean

They’ll laugh as they watch us fall
The lucky don’t care at all
No chance for fate
It’s unnatural selection
I want the truth

No religion or mind virus’
Is there a hope that the facts will ever find us
Just make sure that your are looking out for number 1

I am hungry for an unrest
Lets push this beyond a peaceful protest
I wanna speak in a language that you will understand

Counter balance this commotion
We’re not droplets in the ocean

They’ll laugh as they watch us crawl
The lucky don’t share at all
No hope for fate, its a random chance selection
I want the truth

Try to ride out the storm
Whilst they’ll make you believe,
That they are the special ones, (we have not been chosen)

Injustice is the norm
You won’t be the first and you know you won’t be the last

Counter balance this commotion
We’re not droplets in the ocean

They’ll laugh as they watch us fall
The lucky don’t care at all
No chance for fate
It’s unnatural selection
I want the truth, I want the truth
I want the truth, I want the truth

Selezione innaturale

Rideranno nel vederci cadere
Ai fortunati non importa affatto
Non c’è scampo per il destino
E’ una selezione innaturale
Voglio la verità

Sono affamato di un po’ d’azione
Voglio spingermi al di là della protesta pacifica
Voglio parlare una lingua che possano capire

Dedizione, ad una nuova era
Sarà questa la fine della distruzione e della furia selvaggia?
Un’altra occasione per cancellare tutto e ripeterlo ancora

Opponiti a questa confusione
Non siamo gocce in un oceano

Rideranno nel vederci cadere
Ai fortunati non importa affatto
Non c’è scampo per il destino
E’ una selezione innaturale
Voglio la verità

Nessuna religione o virus mentale
Esiste una speranza che i fatti ci possano trovare?
Basta essere sicuri di fare il proprio interesse

Sono affamato di azione
Voglio spingermi al di là della protesta pacifica
Voglio parlare una lingua che possano capire

Opponiti a questa confusione
Non siamo gocce in un oceano

Rideranno nel vederci strisciare
I fortunati non condividono niente
Nessuna speranza per il destino, è una selezione casuale
Voglio la verità

Prova a uscire dalla tempesta
Mentre ti faranno credere
Di essere quelli speciali, (noi non siamo stati scelti)

L’ingiustizia è la norma
Non sarai il primo e sai che non sarai l’ultimo

Opponiti a questa confusione
Non siamo gocce in un oceano

Rideranno nel vederci cadere
Ai fortunati non importa affatto
Non c’è scampo per il destino
E’ una selezione innaturale
Voglio la verità

Paranoia is in bloom,
The PR transmissions will resume,
They’ll try to push drugs that keep us all dumbed down,
And hope that we will never see the truth around
(So come on)
Another promise, another scene,
Another packaged lie to keep us trapped in greed,
And all the green belts wrapped around our minds,
And endless red tape to keep the truth confined
(So come on)

They will not force us,
They will stop degrading us,
They will not control us,
We will be victorious
(So come on)

Interchanging mind control,
Come let the revolution take it’s toll,
If you could flick a switch and open your third eye,
You’d see that
We should never be afraid to die
(So come on)

Rise up and take the power back,
It’s time the fat cats had a heart attack,
You know that their time’s coming to an end,
We have to unify and watch our flag ascend

They will not force us,
They will stop degrading us,
They will not control us,
We will be victorious

Rivolta

La paranoia sta sbocciando,
Le trasmissioni riprenderanno a breve,
Proveranno a darci nuove droghe per tenerci sedati,
Sperando che non vedremo mai la verità che ci circonda
(Forza)
Un’altra promessa, un’altra menzogna,
Un’altra bugia confezionata per tenerci intrappolati nell’avidità,
E tutte le zone verdi che circondano le nostre menti,
E l’infinita burocrazia che tiene la verità nascosta
(Forza)

Non ci costringeranno,
Non ci avviliranno più,
Non ci controlleranno,
Vinceremo
(Forza)

Scambiando il controllo sulle menti,
Lascia che la rivoluzione si prenda la sua rivincita,
Se tu potessi all’improvviso accendere il tuo terzo occhio,
Capiresti che non dovremmo mai aver paura di morire
(Forza)

Rialzati e riprenditi il potere,
E’ ora che alle vecchie volpi si schianti il cuore,
Sai che il loro tempo è giunto al termine,
Dobbiamo riunirci e veder issare la nostra bandiera

Non ci costringeranno
Non ci avviliranno più,
Non ci controlleranno,
Vinceremo

Is your secret safe tonight?
And are we out of sight?
Or will our world come tumbling down?

Will they find our hiding place?
Is this our last embrace?
Or will the walls start caving in?

(It could be wrong, could be wrong)
But it should’ve been right
(It could be wrong, could be wrong)
Let our hearts ignite
(It could be wrong, could be wrong)
Are we digging a hole?
(It could be wrong, could be wrong)
This is outta control

(It could be wrong, could be wrong)
It could never last
(It could be wrong, could be wrong)
Must erase it fast
(It could be wrong, could be wrong)
But it could’ve been right
(It could be wrong, could be…)

Love is our resitance
They keep us apart and they won’t stop breaking us down
And hold me, our lips must always be sealed

If we live our life in fear
I’ll wait a thousand years
Just to see you smile again

Quell your prayers for love and peace
You’ll wake the thought police
We can hide the truth inside

(It could be wrong, could be wrong)
But it should’ve been right
(It could be wrong, could be wrong)
Let our hearts ignite
(It could be wrong, could be wrong)
Are we digging a hole?
(It could be wrong, could be wrong)
This is outta control

(It could be wrong, could be wrong)
It could never last
(It could be wrong, could be wrong)
Must erase it fast
(It could be wrong, could be wrong)
But it could’ve been right
(It could be wrong, could be…)

Love is our resistance!
They keep us apart and won’t stop breaking us down
And hold me, our lips must always be sealed

The night has reached its end
We can’t pretend
We must run
We must run
It’s time to run

Take us away from here
Protect us from further harm
Resistance!

Resistenza

Stanotte il tuo segreto è al sicuro?
Siamo al riparo dagli sguardi?
O il nostro mondo comincerà a crollare?

Troveranno il nostro rifugio?
E’ questo il nostro ultimo abbraccio?
O i muri cominceranno a crollare?

(Potrebbe essere sbagliato, potrebbe)
Ma dovrebbe essere giusto
(Potrebbe essere sbagliato, potrebbe)
Accendiamo i nostri cuori
(Potrebbe essere sbagliato, potrebbe)
Stiamo scavandoci la fossa?
(Potrebbe essere sbagliato, potrebbe)
E’ tutto fuori controllo

(Potrebbe essere sbagliato, potrebbe)
Non potrebbe mai durare
(Potrebbe essere sbagliato, potrebbe)
Bisogna rimuoverlo in fretta
(Potrebbe essere sbagliato, potrebbe)
Ma dovrebbe essere giusto
(Potrebbe essere sbagliato, potrebbe)

L’amore è la nostra resistenza
Ci tengono separati e non smetteranno di colpirci
Stringimi, le nostre labbra dovranno rimanere sempre serrate

Se viviamo nella paura
Aspetterò mille anni
Solo per vedere ancora un tuo sorriso

Soffoca le tue preghiere per l’amore e la pace
Sveglierai la polizia del pensiero
Possiamo nascondere la verità dentro

(Potrebbe essere sbagliato, potrebbe)
Ma dovrebbe essere giusto
(Potrebbe essere sbagliato, potrebbe)
Accendiamo i nostri cuori
(Potrebbe essere sbagliato, potrebbe)
Stiamo scavandoci la fossa?
(Potrebbe essere sbagliato, potrebbe)
E’ tutto fuori controllo

(Potrebbe essere sbagliato, potrebbe)
Non potrebbe mai durare
(Potrebbe essere sbagliato, potrebbe)
Bisogna cancellarlo in fretta
(Potrebbe essere sbagliato, potrebbe)
Ma dovrebbe essere giusto
(Potrebbe essere sbagliato, potrebbe)

L’amore è la nostra resistenza
Ci tengono separati e non smetteranno di colpirci
Stringimi, le nostre labbra dovranno rimanere sempre serrate

La notte è giunta alla sua fine
Non possiamo fingere
Dobbiamo correre
Correre
E’ tempo di correre

Portaci via di qui
Liberaci dal male
Resistenza!
