Compact *.vmdk does not work (for Fedora guestOS) in VmWare Player

I have a Fedora Linux Guest OS in a VmWare Player.
The hard drive on the virtual machine (*.vmdk file) got to big and I was looking for a way to Compact it.
The compact operation from VmWare Player->Virtual Machine->Edit Virtual Machine Settings->Hard Disk->Utilities->Compact did not do the trick.

The solution came from a VmWare forum thread, the 4-th post from the top:

Assuming the VmWare virtual disk is not pre-allocated and the filesystem is ext4 you will have to manually prepare it to be shrunk.

In the VM, in a Terminal become root and then copy and paste the following command, as is, and then press Enter:

dd if=/dev/zero of=wipefile bs=1024x1024; rm wipefile

Wait for the command prompt to return and then shutdown the VM and then from the Virtual Machine Settings for the Hard Disk select the Compact command from the Utilities button.

The solution worked like a charm.

Giles Duley – Becoming the Story

Another interesting video from TEDx about a photographer who wanted to tell a story.

Giles was a photographer who, some years ago, tired of celebrity photoshoots and the attendant egos and tantrums that often accompanied them, he flung his camera on the photoshoot bed and it bounced out the window into the streets of Soho. At that point he decided to change course and dedicated himself to using his camera to “tell unheard stories of those caught in conflict and economic hardship around the world”. His work took him to Sudan, Angola, Ukraine and Bangladesh among other places. Early last year, on assignment in Afghanistan, Giles stepped on a landmine. Though he became the story, the real story is his photographs.

More information about him are found at this speaker profile page and the interesting blog post about 6 stunning photos from Giles Duley

Risk Intelligence: How to live with uncertainty

Here is an interesting RSA video about risk intelligence.
In the event page from RSA we find out what is risk intelligence:

There is a special kind of intelligence for dealing with risk and uncertainty. It doesn’t correlate with IQ and most psychologists fail to spot it because it is found in such a disparate, rag-tag group of people such as weather-forecasters, professional gamblers and hedge-fund managers. Many people in positions which require high risk intelligence – doctors, financial regulators and bankers – seem unable to navigate doubt and uncertainty.

More information about this video is found on the same page:

Risk intelligence expert Dylan Evans visits the RSA to provide a traveller’s guide to the twilight zone of probabilities and speculation, arguing that we can all learn a lot from expert gamblers, not just about money, but in areas as diverse as dealing with climate change to combating terrorism.

Ebru Art

Ebru Art (or Paper Marbling in English) is defined by wikipedia as:

Paper marbling is a method of aqueous surface design, which can produce patterns similar to smooth marble or other stone. The patterns are the result of color floated on either plain water or a viscous solution known as size, and then carefully transferred to an absorbent surface, such as paper or fabric. Through several centuries, people have applied marbled materials to a variety of surfaces. It is often employed as a writing surface for calligraphy, and especially book covers and endpapers in bookbinding and stationery. Part of its appeal is that each print is a unique monotype.

In the next two videos we can see it in action:

Rhythm and life

Here is a video that shows us that life must follow it’s own rhythm.

Life has a rhythm, it’s constantly moving.
The word for rhythm ( used by the Malinke tribes ) is FOLI.
It is a word that encompasses so much more than drumming, dancing or sound.
It’s found in every part of daily life.
In this film you not only hear and feel rhythm but you see it.
It’s an extraordinary blend of image and sound that
feeds the senses and reminds us all
how essential it is.
