MindMeister: export to PNG bookmarklet

I use MindMeister mindmapping online application quite a lot. Very often, I need to embed an exported PNG image version of a mindmap in an other document.  This operation is cumbersome with the MindMeister currently so I decided to craft one solution available here.

MySQL load balancing



1) The traditional way of handling a two-tiered WEB architecture:


2) The software load-balancing approach:

3) The hardware load-balancing way:



With a versatile (i.e. scriptable) hardware load-balancer (e.g. F5's BIG-IP), one could scale the traditional architecture (see 1) without having to change the application. In this situation, one is trading software development effort against the cost of additional equipment.

Green Software: From Garbage Collection (GC) to Resource Recycling

I confess: I am a recycling freak.  When it comes to better our environment, I am all ears.
