The real Adapter Design Pattern

by Jay Jonas

The Brazilian authorities have recently adapted a new standard for plugs and outlets and they chose a new standard incompatible with the existing Brazilian outlets and with the standards of the rest of the world.

The new outlet looks like the one on the image at the end of this post. It has three round holes.  Plugs with two round holes (like the ones found in some European countries) will work when inserted in the new outlet and they can have either two or three pins (for grounded plugs).

Brazilian outlet: NBR14136-2002 standard.

Brazilian plug: new NBR14136-2002 standard.

But Brazilians developers always can use the Adapter Design Pattern from GoF to plug in their notebooks.  Do not try this at home, childrens!
