Importance of DHA for Human Nervous System Function

90% of the omega-3 fatty acid in the human brain is docosahexaenoic acid (DHA).  It is essential (similar to all vitamins), because the human body cannot produce it itself.  More and more research is being done which reveals how vital this compound is for humans.  For example, it is known that during pregnancy a disproportionate amount of DHA will travel from the mother across the placenta to the developing baby, indicating its vital role in the development of the fetus.

It is now believed that the evolution of the early human brain, differentiating it from that of its primate relatives at a very fast pace, was due to abundance of seafood in the diet.  I.e., early humans were not wandering around the savanna with spears killing rhinos.  They were living by the water eating seafood.  It is highly unusual for an organism to lack the capacity to manufacture a vital nutrient necessary for its survival on its own unless there exists an abundance of it in its diet. has an article about a new study published in Behavioral Neuroscience about the importance of DHA in human nervous system function, “New Study Links DHA Type of Omega-3 to Better Nervous-System Function“.

3-month precipitation forecast map

Today while reading about the current moderate El Niño condition that is occurring, which is part of the larger Pacific Decadal Oscillation, I came across the site of the NOAA Climate Prediction Center, which includes this map which is a three month precipitation forecast for December, January, and February 2009-2010.  The green areas indicate regions where precipitation is expected to be higher than normal, the brown ones less.

Horrific Dark Side to Pedigree Pets

Just read this article at the BBC discussing how a very high percentage of pedigree dogs suffer from serious issues due to genetic inbreeding and breeding selection based solely upon the owners’ interest in the animals’ superficial characteristics.  Its truly gruesome.

While it is said that man’s best friend is the dog, it seems that the opposite is quite untrue for many of these poor animals.

My Favorite Building

I remember the first time that I stepped into the Arcade in downtown Cleveland when I was young.  Going to downtown was such a thrilling experience for me at that young age – it was like there was this fascinating, exciting world of marvels awaiting me. I remember a certain grittiness to it combined with a grandeur – an old, dusty grandeur that was so magnificent it managed to shine through.  I remember the illumination of the building through the wondrous glass ceiling, and the bustle and energy inside the building.

When I first saw the animation film Metropolis it evoked memories in me of the Arcade.  In fact my whole impression of most of the steampunk genre animation I have seen was heavily influenced by not just the Arcade but much of the old part of downtown Cleveland and its dusty, gritty, majesty. The Arcade was where I saw my first hookah shop – an Indian store which had hookahs, bells, incense, and all sorts of exotic things which were new to me.  I still remember the perfumy, exotic scent as though I had entered some other, mystical world.

I always wondered what happened to that majestic building, if it was still standing, and decided to do some searching.  Yaay!  Its still there.  In recent photos it looks a lot cleaner (a lot!) than when I remember it.  I hope that hookah shop is still there…

It turns out that this building is rare indeed and is on the U.S. National Register of Historic Places and listed as a U.S. National Historic Landmark.

This also brings back memories of the time when I was young and I used to go to see the Cleveland Orchestra in the grand Severance Hall nearly every week without fail.  I used to be captivated watching the players of the orchestra as they performed the various great symphonic works.  Their faces often showed a deep solemnity as though they were ministers in some sacred rite or, when the music was joyous, you could feel the exuberance coming through them.

The world to me at this time, growing up near Cleveland, was so mystical, serene, and vast.  It was around this time that I also started practicing meditation, became a vegetarian, and started long-distance running.  Balanced against my adventures through downtown were hours spent wandering through Metroparks or going on long, solitary runs along semi-rural roads near the outskirts of the metropolitan area where we lived.

Even though I know its not possible to go back in time, and even though I have the fondest memories of that time and will always cherish it deeply, I also embrace fully the present moment, filled with dissonances though it may seem.  I believe that all that grandeur and glory that I felt at that time can still manifest within the hearts of those of us who are willing to let it happen.  I believe that we can create a new world that is even more glorious and the music that will come from our hearts in unity and love will be more splendid than the grandest of symphonies.

There will always be beautiful architecture and wonderful music, yet the glorious forms and vibrations that emanate from our souls are eternal.

I am reminded of a saying an artist friend of mine from Germany a long time ago told me: “Lass dich von den kleinen, tanzenden Sternen befunkeln sein.  Und wann sie dich begeistet haben, sei einer von ihnen.”  Let yourself be amazed by the tiny, dancing stars.  And when they have inspired you, become one of them.

Perhaps I will never write a beautiful symphony or architect some grand structure, yet I believe that I can still repay my deep gratitude for the inspiration that has been given me by manifesting brilliance and splendour within my soul.

Command-line client for Network Manager

Configuring a wireless network interface under Linux used to be something that was sufficiently unpleasant to drive new users away.  In Linux there are often multiple ways to do something.  Many times this is a good thing – when you are a Systems Administrator you want to have as many tools and possibilities at your disposal to do things.

Yet for some things, I argue that it is not an improvement.  It can also be a sign of a lack of a comprehensive, elegant, well-planned solution.

As Linux becomes more and more developed, more utilities are developed to make it more user-friendly.  However, I would also argue that progress in user-friendliness can be problematic when the new tools or utilities are developed and become integrated more deeply into systems which do not address the fundamental objectives in a comprehensive fashion, thereby adding unnecessary complexity.

One of the strong points of Linux has to me at least always been the fact that you could easily administer and configure the system from the command line.  Contrary to what administrators without much experience might think, command-line administration of systems is in fact more straightforward and less complex than via graphical interfaces or complex systems which are often designed to make it “easier”.

When Network Manager first appeared it was very welcome as a means to make the configuration of network interfaces, especially wireless ones, easier.  Yet behind the scenes of this tool lies an ugly mess.

The primary method for configuring wireless network interfaces relies upon a  set of wireless tools created by a developer named Jean Tourrilhes.  These include the command-line tool iwconfig


In order to use cnetworkmanager, you still have to kill any running instance of nm-applet.  This seems ridiculous to me.

To actually use it, you run a command like:

Mind-blowing 3D Mandelbrot Fractal Images

Apparently this was a big deal to create.  No one has figured out how to generate 3D Mandelbrot fractal images until now.  These images are simply amazing!
