Finding Rifts

Seth Godin's blog has an interesting article about Steve Jobs. In his estimation, Jobs is "addicted to Rifting--he process of fixing problems, of leaping from one broken market to another. " Godin refers back to an article he wrote in 2000 about people who "find a rift in the continuum of life." And what is a rift? According to Godin, "it's a big tear in the fabric of the rules that we live by. Most people who build important businesses build them on a rift, usually one that they find by accident."

So what are some possible rifts?

  • Why can't I know what other people are investing in?
  • How do I create multiple virtual machines to act as an application server farm?
  • Where did my friend get their last, best travel deal?
  • What cellphone plan are my friends using?
  • Why do I have to have my own contact list in my phone?
  • Why can't I get my shared contacts from my friends?
  • Email isn't a good task manager. Make a clean break between email and tasks.When you get a "to-do" via email, you add the task to your to-do list

Something to keep in mind.

Poor man's VMWare VM cloning

1) Copy the entire directory.
2) vmware-vdiskmanager -n Windows\ Server\ 2003\ Standard\ Edition.vmdk W2K3_R2_Clone1.vmdk
3) Open the Windows Server 2003 Standard Edition.vmx file and change the disk image parameter to point to the new disk:
scsi0:0.fileName = " W2K3_R2_Clone1.vmdk"
#scsi0:0.fileName = "Windows Server 2003 Standard Edition.vmdk"

4) Give the cloned VM a new name in the Windows Server 2003 Standard Edition.vmx file:
displayName = "W2K3 R2 Enterprise Edition - Clone1"
#displayName = "W2K3 R2 Enterprise Edition"

5) Change the name of the VMX file:
mv Windows\ Server\ 2003\ Standard\ Edition.vmx W2K3_R2_Clone1.vmx

Start it up.
