Nokia N900

Nokia did it again and I am in love... again.

Nokia will be releasing the new Nokia N900 soon, the word is the phone will be released in October 2009 in selected markets. I bet US will not be one of the selected markets, which means I have to wait a little bit longer. Damn!.
I was surprised to find out Nokia N900 uses Linux - yes, Linux - especially after Nokia bought Symbian not long ago. I don't think Nokia will ditch Symbin but will probably use it in simpler models or upgrade it a little bit. Actually the phone offers pretty much the same features as Nokia N97, but the OS makes the big difference in the user experience.

Bates Methods for Eyesight Imp

Bates had been taught that vision problems stem from malformed eyeballs, or lenses, or even from the muscles of the eyes themselves being too long or too short. But since no problems of the eye remained static, Bates developed exercises that can help people change their eyes for the better.

The basic exercises are palming, sunning, swinging, and vision shifting.


Rub your hands together to make them warm. (You can shake them or hold them in front of a heat vent if you prefer.) Then close your eyes. Cover your eyes with your warm hands. Make sure your hands do not touch your eyelids and that you do not rest your cheekbones on your hands.

If you want to place the weight of your head on your hands, put the weight on the forehead. I like to lie on my back with a couple of tennis balls under the achy part of my upper back, and cover my eyes with my hands in that position.

Then — this is the exercise — LOOK at the dark. My mom likes to pretend she’s looking at black velvet. If you see spots or zaps of light, so be it. Wait. You will see the dark. Don’t hurry. Do this at least twice a day for 5 to 15 minutes (Hey, that’s what 15-minute breaks are for!).

Also, be sure to drink lots of water. This isn’t in the Bates method — it’s part of what works for me.


Try to do this once a day. It requires a sunny day, or a good desk lamp with an incandescent bulb. The exercise is simple. Close your eyes. Look directly at the sun through your closed eyes. While facing the sun, slowly rotate your head from side to side as far as you can.

This gets the sunlight on the peripheral vision, and it helps bring more blood circulation to your neck. Do this for 3 to 5 minutes. It’s amazing, even on a cold day, how warm the sun feels on your eyes.


Stand with your feet shoulder-width apart, arms hanging loosely at your sides. Look out a window, or do this outside if possible. Shift your weight to your right foot, and swing your upper body to the right, letting the heel of your left foot come up off the floor.

Watch your surroundings as you swing. If you can see a tree out the window or in the distance, notice how it seems to move opposite to the direction you are swinging. This exercise is good for your eyes and your back.

Vision shifting

It’s as simple as it sounds. Whenever it occurs to you that you’ve been spending too much time staring at that monitor right in front of your face, purposely shift your vision to look at the weave of the fabric on your sleeve, or the poster on the wall, or the tree across the street.

Exercises for healthy eyesight

And you thought only physical body requires exercise. There are instances when your eyes get strained and stressed. Like the days you spent staring at the computer screen and felt drained and tired. The toll is taken by not only your body but also your eyes.

The natural state of the body is to be at peace. When we read to understand and learn new information, the mind becomes tense and tries to catch hold. This agitation strains the entire body, including the eyes. This is precisely the reason why people often feel drained after studying or working, even though they have not physically exerted themselves.

Like physical exercise strengthens and de-stresses the body from fatigue, similarly a few simple exercises go a long way in strengthening eye muscles and provide relaxation. The following recommended exercises help counterbalance the effects of eyestrain. The key to doing these exercises is to completely relax and empty the mind as in meditation or yoga.
The following eye exercises are frequently suggested by most health care providers:
Improve Visual Concentration

The first step is to strengthen visual concentration. Sit comfortably with your back and neck straight but not stiff. Start by holding each below mentioned posture for a few minutes and gradually increase the time.

Focus your gaze on the tip of your nose without blinking. Remain in this position for as long as you can. Then close your eyes and relax.
Focus on your ?third eye? without blinking. This is the area between the eyebrows above your nose. Then close your eyes and relax. It may feel uncomfortable or hard to do at first, but do not give up. Keep your focus on that area and with time, you will find this posture easier to do.
Without turning your head, focus both eyes on your left shoulder. Remain in this position for as long as you can. Then close your eyes and relax. Repeat this sequence with the right shoulder.
After you are finished, place the palms of your hands on your closed eyes and rest for some time. This will help eye muscles relax.
Imagination for better eyesight

This is another exercise to improve visual concentration. First lie on your back facing up. Your palms should face the ceiling and your legs should be about shoulder-width apart. If you are doing this exercise in your office then sit comfortably in your chair.

Close your eyes. Breathe into your stomach. Feel it expand as it fills with air. Continue breathing in and out for a few minutes and then open your eyes. Pick a stationary object to look at. Close your eyes again and continue ?looking? at that object. This exercise helps to relax your eyes. It also balances mental focus with imagination.
De-stress your eyes

Like the previous exercise, lie on your back facing up with palms facing the ceiling and legs about shoulder-width apart. Sit comfortably in your chair if you are doing this exercise in office.
Close your eyes and place your palms over your closed eyes. Breathe into your stomach. Feel it expand as it fills with air. Continue breathing in and out for a few minutes and then open your eyes. Pick a stationary object to look at keeping your mind empty. Do not attach yourself to it or stare at it. This exercise teaches you how to focus without straining or depleting your eyes.

The above three exercises help in improving and strengthening visual concentration. However, these alone are not enough for effective eye strengthening. Eyes, as we all know, are subjected to so many ordeals that cause various forms of discomfort and sight problems the most common being headache. The following set exercises that form a part of yoga aim to provide relief and strengthen eye muscles.

Sit at the edge of your chair with your back straight. Close your eyes and place the palm of each hand over an eye, so you feel your palms warming your eyes.
Remove your hands, keeping your eyes closed. Inhale deeply through your nose. Exhale and let your head drop forward than rotate it from side to side. Then shrug your shoulders, making circles with them forward and backward.
Close your eyes tightly and lift and tighten your shoulders as much as you can. Hold for a few seconds and then exhale, suddenly releasing your shoulders and opening your eyes. Repeat this several times.
Blink repeatedly, fluttering your eyelids until your eyes become moist. Repeat this several times.
Breathing naturally and focus on an object far away from you for about half a minute. Try to maintain your focus, blink rapidly several times. Then focus on a nearby object for about 15 seconds. Try to maintain your focus and blink rapidly several times.
To counteract the tendency to squint, look up while exhaling with eyes half open.
This exercise helps the extrinsic muscles that move the eyes. Try to keep your head straight and in line with your spine. Roll your eyes into all of the directions below while exhaling. Hold for a few seconds and then return your eyes to the center while you inhale.
Keep your head straight and look at the object ahead. Exhale and look from side to side without turning your head. Now try to exhale and turn your head from side to side several times letting your eyes follow the head movement. Then turn your upper body from side to side and let your eyes follow the body movement.
Place your palms over your eyes to warm them. When you are ready, remove them and open your eyes.
All these exercises done at regular intervals with proper care on inhaling and exhaling of air provide satisfactory results. For safeguard eyesight and de-stress eyes from strain one should take a break from work for a few minutes that exposes to potential things that cause eyestrain.
Good luck

Michael Crichton 1942 - 2008
I am very upset with the news. Michael Crichton was one of my favorite authors. I have read and enjoyed all of his books. It is really hard to say which is my favorite book, since each one is very unique and they are difficult to be compared to each other. However, Prey and Timeline are the ones that really, really impressed me. I was so waiting on the next book to come out and I was very upset and I am still upset of the news. RIP.

How to calculate Julian dates?
The Julian day system was introduced by astronomers to provide a single system of dates that could be used when working with different calendars and to unify different historical chronologies. Apart from the choice of the zero point and name, this Julian day and Julian date are not directly related to the Julian calendar, although it is possible to convert any date from one calendar to the other.

So, I found a couple of methods to calculate the Julian date and here they are:

1) The wikipedia way:

int a = ( 14 - month )/12;
int y = <year> + 4800 - a;
int m = <month> + 12 * a - 3;
double jdn = <day> +
     ( ( ( 153 * m ) + 2 ) / 5 ) + 
     ( 365 * y ) +
     ( y/4 ) -
     ( y/100 ) +
     ( y/400 ) -

2) Another way:

yy = (int)( y - Math.floor( ( 12 - m ) / 10 ) );
mm = m + 9;
if( mm >= 12 ) mm -= 12;

k1 = (int)(( Math.floor( 365.25 * ( yy + 4712 ) ) ) );
k2 = (int)(( Math.floor( 30.6 * mm + 0.5 ) ) );
k3 = (int)(( Math.floor( Math.floor( ( yy / 100 ) + 49 ) * 0.75 ) - 38 ) );

jd = k1 + k2 + d + 59;
if ( jd > 2299160) jd -= k3;  // for gregorian caledar

Nokia Morph

Nokia Morph is a concept of a cell phone that will uses nanotechnolgies and all of their advantages. Here's what it will look like:

Nokia Morph

Yes, this is the same phone. Due to the nanotechnologies, the phone will be able to change its form, hence the name, Morph. The materials from which the phone will be made will be flexible, stretchable, and transparent. They will be dirt and water repellent as well, so you will be stuck with a clean phone :). The phone will use solar power to charge itself. So far, this is incredible. But I was even more amazed by the fact 2that the phone will have sensors that can detect air pollution, the quality of the environment, and much more. I am really amazed by this phone. This is a great concept and I cannot wait for it to become a reality. Here's a link to the Nokia's website:


Go, Nokia!

Old thermometers

An air thermometer , an open-ended tube partly filled with water or alcohol ,a sealed liquid thermometer, at near right. The air thermometer was already well known at the time, but historians had previously credited the liquid thermometer to Ferdinand II, Grand Duke of Tuscany, in 1654. The small lettering to the right of the liquid thermometer says oleh, "ascending," the direction of the brandy when the bulb gets warm.

The instrument had an open top, making it an imprecise and impractical instrument needing frequent refills to replace evaporated alcohol. "Delmedigo's thermometer was in fact accurate enough, "that you could measure the change in temperature from day to day.
