what single discovery has given you the greatest boost in productivity?

As a programmer what single discovery has given you the greatest boost in productivity?

this question has been ask in the stackoverflow and I think my answer was great one

pencil and a paper (simple obvious) but still underestimated                         

We took an consultant (mogobe.com)

As I mention earlier we just finish a year of development and the thing that i am most proud of except the the game is working an kids are having fun.

Is that we have an consultant the credit for that i need to give to eyal

I am not shore that he is the best one but,

I know that he know well enough that I can listen to.

I know that he can explain and communicate his idea.

I know  that we is smart enough to lessen to me.

I honesty think that event thus that it cost a allot of money it is a good way to spend it especially if you are small company in it s  early stages.

We toke Moshe shamy from sela.

We are still looking for consultant for the client side so if you think that you are the one you can contact me

After a year of development ( of mogobe virtual world )

After a year of development  quit alto form my perspective never been a leader for a project of that scale

And it kind of hard to look on it and say that what we accomplish in year me and  Tzahi ( the  development team )

yes it was new thing for us and ,yes we learn allot from it,

yes it is nice yes it is fun but I could have done it better

but it is probably the filling of any programmer that standing in front of a big project that he develop .

here is it www.mogobe.com it is virtual world for kids.

My mistake when I used Google analytics

I am project manger of virtual worlds for kids this game call Mogobe 

and i did fatal mistake.

We add Google analytics  to the site by using a simple java script API in all the we pages of the site.

After it we wonted to get more spastic information and because this is a virtual Wolds for kids most of

the activity is happening inside the flash player.

We added the Google analytics  flash API that send more data to Google analytics  service

and that was my mistake I did not understand it in the begging because when we did it there where little traffic in our site

only after a while the figure didn't really match the one form our data base and the one from Google analytics. 

And in that moment we understand that when we used to different API of Google analytics each will create a new user and a new visit.

So in the if you have a site that have flash content do not try to use the flash API to track your users activit.

Make flash call the java script API that you all ready have in your site.
