Where is Zed?

Yesterday, I said goodbye to a dear friend.

I will remember him for the joy, and for the good times.
love you, Shay!

Look over us.

Rails Application variable II

Ah, it turns out that my heist and ignorance in Ruby and Rails I missed out on the Rails.cache options.
All you need is...


  def self.alive? (id)
    if Rails.cache.read(id)!=nil and (Time.now - Rails.cache.read(id))<10
      true
    else
      Rails.cache.delete(id)
      false
    end
   
  end
 
  def self.present(id)
    Rails.cache.write(id,Time.now)
  end

(...love)

Rails Application variable

It almost seemed that there was no easy way out of putting application scope variables in the database.
But there is a way out:
    if Thread.main[:uuid] == nil
      Thread.main[:uuid]=0
    end
    uid = Thread.main[:uuid] += 1

This code accesses the mail thread of the rails process and puts a variable on it. (the thread is an object and can have key => value sets)
And since rails has only one main thread... its shared with all the threads underneath.

Good Luck

Multilingual Support for Flex

Some Cowboy coding techniques for supporting multilingual flex interfaces:
Instead of the usual form (from an Adobe development center post):
...text="{resourceManager.getString('resources', 'POSTDISPLAY_POST_TITLE')}"...
My label looks like:
...text="{gS['POSTDISPLAY_POST_TITLE']}"...
Which is so much shorter and nicer to read when you are coding.

The gS is actually a static object (i.e. hash map) that I load with all the key:value pairs of the language.
Once you declare gS as [Bindable] you can replace the object at runtime with other languages, resulting with the replacement of all the strings in the application.

Note: the compiler issues a warning that since you are using square brackets, the GUI object will not be able to detect changes in the data source. Well, it does.

"localhost" Server isn't working? Blame Skype!

It took me a while to reach this grim conclusion, The Skype client blocks quite allot of communication ports on the machine its running on. Apache Tomcat, WAMP and RoR are effected (as far as i can tell).

 
Solution:
Kill the Skype process.

Good Luck.

Exporting from SQLServer to SQL insert script

The problem:
Export data from an MS SQL server to an SQL script of insert statements

It appears that there is no built in option for performing such a simple a task. After all, SQL is the common protocol for SQL based databases.

What i did manage to find is a script (stored procedure) for SQLServer 2000 and SQLServer 2005
The original post and instructions are available here.

Good luck
