If you have equal read/write then Hash

And forget for OpenStruct

Here is why and how I benchmark all those methods



ActiveSupport::SecureRandom.hex(16)

The client was very happy because he can imagine his website.

Now I am considering to buy or make such nice tools :)

1. Pencil

Pencil (free) is a Firefox plugin that professes to enable you to build wireframes and prototypes. As a prototyping tool it’s quite good, allowing you to quickly put together a reasonably high fidelity mockup. However, be aware you’ll still need to produce the visual design elements for Pencil, as it relies on dragging and dropping pre-made graphical elements.

The output wireframe elements that ship with Pencil do tend to be based on the look and feel of a Windows desktop application. This really is undesirable for a web application, however you could modify this with your own page elements.

Another downside of Pencil is that its export functionality provides only a few image formats. This means that Pencil falls short of being a real interactive prototype development tool.

Balsamiq Mockups

Balsamiq Mockups (price:$US79, demo available) is an interesting product running on Adobe AIR. Its representation of the interface elements has a refreshing hand-drawn, sketch-like quality to them. This does help promote the degree of changeability of the wireframes, as they look very much like a draft. If you lack the skills to create hand-drawn sketches then Balsamiq is a useful tool, as it allows you to produce quality roughs. Balsamiq also offers a standard collection of interactive screen elements, which is helpful to start off with.

http://gomockingbird.com/ is like balsamia

https://www.jumpchart.com/ – for very simple pages- I cant find how to change the layout.

When you catch a junior in mistake – let him contribute to the open source community. Not with coding. With translating. Take some open project and translate it to your native language.

Maybe after all the junior will release that he is much happier to translate than coding :)

win-win condition.

N.B. On the picture – Young coder is coding in Word.

Currently to start with Rails you have to learn a lot of stuff which are added just now and is not sure how long they will stay.

Also Rails is not targeting the developers to be fast but is targeting to be the perfect framework.

The price for that is that almost a year and a half there is no new version while the they refactor it.

No goodies like scafolding, only enterprise stuff around.

That is my personal opinion on this framework.

As I like to say – you cant leave your followers without food for such long time.

<%= select(“city”,”kind”, t(:place_types).map.map!.each{|key, value| [value, key]}, {:include_blank => t(:chose), :selected => @city.kind}) %>

The bad code

t(:place_types).map.map!.each{|key, value| [value, key]}, {:include_blank => t(:chose), :selected => @city.kind})

the replacement

key_values = t(:place_types).collect{|key, value| [value.to_s, key.to_s, ]}

Rails.ouch.ouch.omg!

If you read it now and get it – you will be ok, else you will learn all those rules by own in the future.

The first time I saw this gem  I was very excited about it.

With only a few lines of code an you have the whole search done. I have start using it.

Once I want to apply it to a complicated search. The problem was that I have to write more code and “patches” in order to keep the Searchlogic working….

So my advice is – don’t use such boosters if you can apply your own solution. There will be aways a time when you want to extend your search and you will loose a lot of time search how to do it with the 3rd party solution.

Do it yourself.

If you think that by hiring juniors you will save money and will get working application – you are wrong.
You will loose much more than money.

Yes they are low cost, but read the rest of the post to be not tricked.

Forget for nice and reliable code

Most of the time the developing is done by using some standard patterns which the experienced developers apply without even thinking. You don’t have this from a junior – you will have “private” code which in the best case will NOT work. In the worst case it will work only in one way and you will have to fix this code at the end of the project when your time is less. DO NOT give them to commit code – leave them for years working the most misarable work that you can find untill they show that they deserve to trust them.

Rewrite their code

Most of them produce code that have to been rewritten. All the code they write is code that is invented. They hope their code will work but their vision is limited because of their experience.  To know where might your code will fail you have to been working for years in this field.

If a developer writes a code the chance that it will be ideologically wrong is very small. But if a junior write a code – then be prepared to rewrite big portions of your application. Things get worse when you discover this late – near the time your customer waits his applications.

Good working environment

They take the power from the experienced developers by asking them questions. And instead your powerful developers to work at full power they get distracted from work and the those with the leak souls start to believe that they are The One (by answering easy questions from the newbies). Your good developers will become like the juniors.

Prestige of the company

If you work in a company which have a name – imagine what will other think if some junior says that he learned this (code) in your company!

You are responsible for them

If something breaks -  you are the one which is responsible for their actions.

I have been working with juniors for 2 years before I realize that this is not working. In case you have already juniors – make them suffer until they go away or become real pro :)

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

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

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

Here is presentation of mongo  and here are some slides

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.

Check those

The interesting think is that two of them are on Rails (www.mebelicomfort.com, shop.djibutzo.com) , one of them is on WordPress and the last one is on some custom PHP framework.

And meanwhile we are doing a lot of refactoring on our company website psspy.se, which finally is starting to look good.

After so much work I think that I will be tired but I am ready now for 6 websites for 1 week.
