6 degrees of seperation - what a small world

The 6 degrees of seperation is theory stating that any one on earth can reach another person on earth through a chain of acquintances that has no more than 5 poeple in between.
For example, if you want to send a gift to Madona, call somebody you think he/she knows madona! chances are she/he does not know her personally, but then again, that person shall try to contact another person. If the chain continues, the gift is bound to reach Madona after 5 links (contacts). Maybe one can try this through the Linked-In network as well.

The theory was first proposed in 1929 by the Hungarian writer Frigyes Karinthy in a short story called "Chains."

" In 1967, American sociologist Stanley Milgram devised a new way to test the theory, which he called "the small-world problem." He randomly selected people in the mid-West to send packages to a stranger located in Massachusetts. The senders knew the recipient's name, occupation, and general location. They were instructed to send the package to a person they knew on a first-name basis who they thought was most likely, out of all their friends, to know the target personally. That person would do the same, and so on, until the package was personally delivered to its target recipient.

Although the participants expected the chain to include at least a hundred intermediaries, it only took (on average) between five and seven intermediaries to get each package delivered. Milgram's findings were published in Psychology Today and inspired the phrase "six degrees of separation."

Presenting PowerPoint to business executives , The 10/20/30 Rule and the Meniere's Disease

Guy Kawasaki wrote an article how to write a practical presentation for the business community. The guy (whose name is Guy) is a ventrure capitalist who listened to hundreds of presentations for people trying to sell their companies. Here is what Guy said in his 10/20/30 Rule

a PowerPoint presentation
should have ten slides,
last no more than twenty minutes,
and contain no font smaller than thirty points

Ten is the optimal number of slides in a PowerPoint presentation because a normal human being cannot comprehend more than ten concepts in a meeting—and venture capitalists are very normal. (The only difference between you and venture capitalist is that he is getting paid to gamble with someone else’s money). If you must use more than ten slides to explain your business, you probably don’t have a business. The ten topics that a venture capitalist cares about are:

• Problem
• Your solution
• Business model
• Underlying magic/technology
• Marketing and sales
• Competition
• Team
• Projections and milestones
• Status and timeline
• Summary and call to action

You should give your ten slides in twenty minutes. Sure, you have an hour time slot, but you’re using a Windows laptop, so it will take forty minutes to make it work with the projector. Even if setup goes perfectly, people will arrive late and have to leave early. In a perfect world, you give your pitch in twenty minutes, and you have forty minutes left for discussion.

The reason people use a small font is twofold: first, that they don’t know their material well enough; second, they think that more text is more convincing. Total bozosity. Force yourself to use no font smaller than thirty points. I guarantee it will make your presentations better because it requires you to find the most salient points and to know how to explain them well. If “thirty points,” is too dogmatic, the I offer you an algorithm: find out the age of the oldest person in your audience and divide it by two. That’s your optimal font size.

Then Guy adds a comment

"So please observe the 10/20/30 Rule of PowerPoint. If nothing else, the next time someone in your audience complains of hearing loss, ringing, or vertigo, you’ll know what caused the problem"

Guy actually starts his blog by saying that he suffers from something called Ménière’s disease,

The symptoms of Ménière’s include hearing loss, tinnitus (a constant ringing sound), and vertigo. Guy claims that there are many medical reason that cause Ménière (too much salt, caffeine, or alcohol in one’s diet, too much stress, and allergies)

Guy then says that he is not subjected to any of the above causes, but he still gets Ménière’s disease. I Guess Guy was trying point out to the medical community that the audiance on NON 10/20/30 Presentation are prone to develop the Ménière’s disease as well.

Chargers Chargers everywhere, but not ..

I was trying to mimic "water, water everywhere but not a drop to drink". Obviously, i am not as good as Samuel Taylor Coleridge when he composed Rime of the Ancient Mariner. I remembered this poem that was part of our O level syllabus (Way back then) when I was looking for my digital camera charger at home. Literally, there are more than 10 charges at home, but these chargers are never interoperable. One charger for my SONY laptop, another for my wives DELL laptop, one for my E71 Nokia, which does not work for her Nokia, a couple of old mobile chargers, one for the electrical shaver, one for the miniature hover and many more.
What wrong with electrical appliances manufacturer! They do not get it, Cannot we just make 2 or 3 standard models that all manufacturers can use. The idea is not far fetched! In fact, it is already implemented by battery operated devices. Why can i use the same battery set for all the different Remote Controls (for example). There are a few standard sizes and then you do not have to get the battery from the same manufacturer, nor do you have to have dozen of different batteries that cannot be used when you need them! In management, everybody is talking about standard operating procedure and all kinds of standard, ISO, IEC, EN, DN, and ANSI covering many different industries. Does it require a UN resolution to enforce standard chargers!

Secret

"You are God in a physical body.
You are Spirit in the flesh.
You are Eternal Life expressing itself as You.
You are a cosmic being.
You are all power.
You are all wisdom.
You are all intelligence.
You are perfection.
You are magnificence.
You are the creator,
and you are creating the creation of You on this planet" (p. 164).

A best selling book (DVD) The Secret, by Rhonda Byrne and is spreading like crazy in the USA, especially after making it to the Oprah Winfrey Show. More than 16 million copies sold (BTW, any book selling more than 4000 Copies in the Arab World, makes it to the best selling list among arabic publication- sadly)
I did not read the book; i read reviews about it and would like to share this review with you

"The essence of The Secret is "the law of attraction." According to Byrne and the twenty-nine co-contributors whom she quotes extensively, everything in the Universe (which is always capitalized and usually synonymous for "God") vibrates on a particular frequency. When you think in harmony with the frequency of something, you attract it to you. If you think about wealth, you will receive wealth. If you think instead about your debt, you will receive more debt. You attract what you think about; your thoughts determine your destiny. Byrne restates the law of attraction in various ways: "Nothing [good or bad] can come into your experience unless you summon it through persistent thoughts" (p. 28). "Your thoughts are the primary cause of everything" (p. 33). "Your current reality or your current life is a result of the thoughts you have been thinking" (p. 71). According to the product description on the DVD, "This is The Secret to everything—the secret to unlimited joy, health, money, relationships, love, youth: everything you have ever wanted."
reference
http://www.spiritualdisciplines.org/secret.html

from my background in physics , we learned that when things vibrate in harmonious frequencies , they resonate but not Attract. Therefore, i am not sure that the essence of this book has any scientific support. Additionally, the Likes repel and do not attract. If i want to say that if i think about wealth a generate Positive charges and that wealth itself is positively charged, then no attraction should take place (With the exception of semiconductors, where positive charges can flow against the flow of positive charge - or the electrical field- due to changes in energy level and minority carriers having enough energy to cross the energy field barrier. A theory in solid state physics that made diodes and transistors become realities)

It is a controversial book, not only scientifically, but also religiously ..Not only is this evident from the starting paragraph of this post, but also in the following

The earth turns on its orbit for You.
The oceans ebb and flow for You.
The birds sing for You.
The sun rises and it sets for You.
The stars come out for You.
Every beautiful thing you see,
every wondrous thing you experience,
is all there for You.
Take a look around.
None of it can exist, without You.
No matter who you thought you were, now you know the Truth of Who You Really Are.
You are the master of the Universe.
You are the heir to the kingdom.
You are the perfection of Life.
And now you know The Secret (p. 183).

Nine more rainy days

It was an interesting day yesterday (weather wise). it snowed off and on during the day, and the last wave of snow was at about 8:30 in the evening, i was real heavy, i must add. While at home, you know if snow is accumulating or not, by the fact the satellite channels. Of course, when the dish is covered by snow, the reception ceases. At this point, even one lives without TV or one has to get on his/her feet and shuffle the snow off.

This morning, it is cold and the skies are overcast. No precipitation of any form. The snow has almost completely melted. This is just normal considering the fact that the current temperature is 6 degrees.

As you can see on the weather map on the left, the low pressure system has moved to the north east as shown by the arrow. I expect this as the "Kiss Good bye" weather system as we are moving towards Spring. This does not mean, no more rain, but nothing like what we witnessed in the past 48 Hours.

The total precipitation during the storm is around 50 mm and the total rain fall this season, so far, is about 85% of total seasonal rain. However, the so far amount is, in line with the average for this time of the year. The no of rainy days so far is 53 days, and total rainy days per season is 62, so one would expect 9 more rainy days

Snow or no Snow, and this is the answer

Location: My office Abu Elhajj comercial complex office 805 room 201
Time : 8 AM
Outside Temperature : 1 (One) degree above freezing
Precipitation form : Snow
current condition : Snowing

It is actually snowing, but the accumulation on the ground is little, maybe not cold enough or because it was raining all night. There is a white cover of not more than 2 cm.

Snow or no Snow, this is the question

This is my first weather-centric post!!I was looking at weather forecasting maps, and i think it

there is a weathe system that is worth talking about. By the way, weatherwise, last month was a quiet month. The rain fall was below seasonal averate; wet weather is really welcomed at this point.
To follow why, first look at the image on the left; if you can NOT geographically recognize the boundaries of the eastern med, then, now is the best time to quit reading, otherwise keep going

There are semi circular line (Light green, green, reddish etc).. These are call isobars. These circles connect points where atmospheric pressure values are equal.

Can you spot Cyprus?, it is surrounded by light blue circle! This is the center of a Low Pressure System that is affecting the Easter Med. You can also read the pressure value on the map. the center of the system is at 1006 millibar This is not directly shown on the map, but the outer circle reads (08) which is an abbreviation for 1008.. The normal atmospheric pressure is around 1022 mb. Low pressure system cause instability and therefore, active weather conditions (wind, rain etc..).
The button line is, there is a fairly deep low pressure system centered around Cyprus that is likely to affect the area for the coming 24-48 hours.

Snow or no Snow?
The low pressure system causes the wind system to revlove around its center in an anti-clockwise manner (in the northern hemisphere). If you can track the where the wind is coming from , you can find out if it is going to be cold or not.. As this is not to teach you how to read weather maps, there is an indicator on the map that can give you a hint about how cold the winds are. Look at the black line with 540 reading. We call this the snow line, because this line indicates zones where temperature approaching zero may occur. Look back to the map, and you will see that the bounders of this line cross the eastern med and Jordan. So yes, there is a chance of snow at higher elevation in Jordan

Lets wait and see,, this is all predictive modeling after all

better to know 'cpio' before getting down to the serious business

A Real Techy post, OR should I say a real Techie post
Both work well, Techie is a term, derivative of the word technology. This post is really on the Tech side, Techy a variant of tetchy (easily irritated or annoyed)

This post is a bit of both,
but you will see in the end of the post , the findings are not really techy

I am spent the entire morning upgrading our Oracle portal platform to version 10.1.4
I just downloaded the binaries from Oracle Site
One file was downloaded (as_linux_x86_portal_1014.cpio)
The installation manual assumes that you have the CD media
The installation command is really straight forward

$mrua.sh -oracle_home /home/oracle/infra -oid_host asdb.realsoft.com -oid_ssl_port636

Thinking i am thee linux cpio expert (which i only use while installing oracle products by the way), i thought i can remember the command of my head, fa i wrote

cpio -icvf (smaller than sign) as_linux_x86_portal_1014.cpio

when command finished running and i ran the mrua.sh command as instructed

immediately i ended up with

could not find javalib.so
COULD not find java 2 Runtime Environment

how can this be the case, when all other applications use the JRE

This where i spend most try all possible techniques to make sure JRE is really exposed.
After thorough investigation, i found out the mrua scripts uses the JRE that is contained within the portal upgrade binaries. I looked into the JRE subdirectories in the main directory under which the portal upgrade binaries were loaded, but i found no libraries.

Well, all of that happened because i thought that checking the cpio command is a waste of time. The contrary proved to be quite true is this case

The correct command is

cpio -idmv (smaller than sign) as_linux_x86_portal_1014.cpio

it is the d in the idmv

My New LCD TV

To add to my TV view pleasure, i wanted to buy a new Flat TV. (do not laugh, but i spend most of my time on TV while asleep)

As normal, i do not embark on engaging in new project without enough thought.
I wanted to buy flat TV. Naturally, i was confronted with many issues that i needed to resovle before buying one


1- How many inches
2- LCD or Plasma
3-most importantly ,, the Brand

After some research i found the following

1) for the size, you might be confined with the size of the room. One has to keep a distance between the seat and the TV. For the best viewing pleasure the following are guidelines

For 32 Inch TV 2.4 meters
For 37 Inch TV 2.7 meters
For 40 Inch TV 3,0 meters
For 42 Inch TV 3.2 meters
For 46 Inch TV 3.5 meters

Because i m not planning to buy a new house just for the TV, i figured it would be wise to choose a set that suits the current dimension of the existing sitting root. It best scenario (w/o changing decoration and with all wires hidden) was 37 Inch


2)LCD or Plasma

There are two compelling advantages with an LCD TV. The first is that they can be much easier to watch than a cathode ray tube (CRT) model. This is because screen displays are significantly brighter with a high contrast and the flicker free picture. LCD TVs will work effectively in almost any kind of room lighting from bright to ambient. Secondly, LCDs have a higher native resolution than plasma TVs of the same size making them ideal for high-definition output. While plasma TVs are currently better at the moment for sheer screen size, as more and more television output becomes high-definition TV (HDTV), LCD technology will come to the fore.

3) Brand

S O N Y came as my initial bet, unfortunately, the Sony dealer has limited range and when compared with the market prices of SONY LCD across the world, the Sony dealer here in Jordan is not doing a good job. There is no 37" in Amman, and the 40" sells for 2600 JD.
My research has shown that Samsung is well ranked worldwide, but again, the dealer in Amman carries the 32" and the 46" only and (for some reason) even the next shipment will not have 37" , 40" range (i think Samsung competitors cannot get any luckier than this, what an ideal competitor; Samsung must be thinking of a marketing plan that really beats me).
When i was looking for the top selling LCD TV, SONY and Samsung were ranked among the best, but, i could not get what i wanted in Amman. SHARP came to my rescue, i bought a 37 Inch SHARP at a price tag of 1600 JD, the 42" model is selling for 1900.

It is a nice TV with good crisp picture. These TV can give excellent picture if you feed High Definition (HD), signal. However, it is seldom the case that we get HD signal in the current set of Satellite Channel. I thought the MBC have the best signal so far.

But this is not where the excitement is!!!
I found out that it has a Computer input, meaning that you can connect your laptop and here you go, a 37" Computer Screen. For obvious reasons, my wife was not particularly happy about this discovery. For my, it was really a thrill, with a wireless keyboard, wireless mouse, high power laptop and a large flat panel LCD display, the sitting room has been transformed "be anywhere" always wired, digital sitting room.

i will take a picture of my new LCD and show it to you soon

Hindsight is 20/20 What about my Name Ammar

I lived 4 years in the USA back in the 80s,
i thought that it should be easy for Americans to pronounce my name correctly (Ammar). I was easy on the fact that the fist letter of my name cannot be pronounced by native English speakers, but thought that the rest should be OK. I thought that the Double-M is enough to for the American to understand that there is an Arabic "Shadda" over the Letter M.
However, i think they should be excused when you consider the following:

The only English word that gets as close to my name (Ammar) as possible is (GrAmmar)
But how do we Arabic Native speakers pronounce the English Grammar, now remove the first two letter and there you go, you have just mis-pronounced me name. Only now i have come to realize that native English speakers ought to be excused, it looks too obvious now, but as the saying goes Hindsight is 20/20 .
Sorry, i misjudged things for just too long!!!! and the time has come for me to realize my mistake... By the same token, i am afraid there are so many things (situations, people) that i misjudged.

Conclusion: The way i write my name in English (Ammar) is wrong!!! How then should i write my name???

By the way, i learned the word Grammar during my early years in school. Quite honestly, the resemblance to my name did not come at that stage, but much later. This is only to illustrate, how much of seemingly obvious things we human (or i should talk about myself). God knows how many of these seemingly obvious things that i still miss.
As one of them said : Among all the things i miss, i miss my mind most
