The Nexus 10 Is Better Than the Nexus 9

Google may have made a mistake in releasing the new Nexus 9. It improves very little on the old Nexus 10, and even may have taken a step back in a few categories.

The Nexus 9 has a better processor.

The Nexus 9 has a metal frame and a lighter body.

The Nexus 9 has a better back camera and flash.

The Nexus 9 will get more Android updates.

Both devices have 2GB of RAM.

Both devices have a similar front camera.

The Nexus 10's screen is bigger.

The Nexus 10's display has a higher pixel density.

The Nexus 10 has a bigger battery.

The Nexus 10's 16:10 aspect ratio is better for videos, while the Nexus 9's 4:3 aspect ratio is better for web browsing. Some games work better on 16:10, some work better on 4:3.

The Nexus 9 is a bit smaller and more pocketable, while the Nexus 10 is better for media consumption.

Currently, the Nexus 10 32GB is $425.99 on Amazon.

The Nexus 9 32GB is $429.99 on Amazon.

The Nexus 10 is clearly the better bang for the buck. The Nexus 9 is a mistake.

The Half-A-Loaf Approach

A common way of approaching a problem is the half-a-loaf approach. Here's an example.

Let's say a student is faced with a matching test:
========================================================================
COLORS TEST
Match the fruit with the corresponding color.

___1. Grape      A. Green
___2. Banana    B. Purple
___3. Pear        C. Yellow
========================================================================
Assume that the student knows for certain that grapes are purple. The student's paper now looks like this:
========================================================================
COLORS TEST
Match the fruit with the corresponding color.

 B  1. Grape      A. Green
___2. Banana    B. Purple
___3. Pear        C. Yellow
========================================================================
Now, the student is stumped. He doesn't know what colors bananas and pears are. So he decides to use the half-a-loaf approach. The student's reasoning is as follows.

There are four possible situations.

Possibility One: (1. B) (2. C) (3. A)   Score: 100%
Possibility Two: (1. B) (2. A) (3. C)   Score: 33%
Possibility Three: (1. B) (2. C) (3. C)   Score: 66%
Possibility Four: (1. B) (2. A) (3. A)   Score: 66%

Getting a 100% would be pleasant.
Getting a 66% would be bad, but not horrible.
Getting a 33% would be devastating to the student's average grade.

The student should avoid the 33% at all costs.

The student now has two choices: either put different answers for all the questions, or put the same answer for two of the questions.

The former gives the student a 50% chance of getting a 100% and a 50% chance of getting a 33%.

The latter guarantees the student a 66%.

The student picks the latter, securing a 66%.

Technically, the two choices are intrinsically the same, because the former choice would, on average, give the student a 66% anyway. But in a real life situation, the latter choice is better because it avoids the 33%.

This is the half-a-loaf approach: being certain of getting half a loaf of bread is better than having a chance of getting no bread.

How Dreams Came to Be

How Dreams Came to Be

George Rao

Joe was the god of the sky, earth, and oceans. He was so powerful and wise, that he could lift tall buildings, jump past vast mountain ranges, and decode complex mathematical equations with ease. Joe was taller than the Statue of Liberty and stronger and faster than a horse. Despite his awesomeness, he could not resist the thing that threatened to remove all joy from the world.

The Evil Spirit was pure evil. It was made up of the souls of wicked wizards and the blood of gambling gangsters. It was made up of Internet viruses and Windows errors. It was made up of the very essence of evil. The Evil Spirit had neither shape nor form, so it could only inhabit the mind of a living being. The person had to have the strength of a tiger and the courage of a lion. Who did? The Evil Spirit chose Joe. It crept into Joe’s mind and gave life while asleep. This new invention was called a “dream”.

Although Joe was the ruler of the sky, earth, and sea, he did not have control over the other elements. Joe desperately longed for more power in the universe. Using this, the Evil Spirit taunted him: “Do you want control over fire and lava? Do you want control over iron and gold? Do you want control over love and marriage? Join me, and we will have power over everything!”

“What’s your problem?” Joe exclaimed. How dare you enter my mind without downloading the you-may-enter-a-god’s-mind iPhone app?” In the dream, Joe walked over to the personification of the Evil Spirit and attempted to smash him to bits. With his first step, the Evil Spirit flew out of the body, and Joe collapsed.

After thinking about it in bed for a few hours, Joe finally decided: “Ok, I will join you.” “Good.” Suddenly, a voice in his head talked. Using the power of Joe’s broken will, the Evil Spirit broke into his mind. Having gained the power of Joe, it was now easy to steal the other gods’ powers. The Evil Spirit channeled this power to cast away happiness from the world. Flowers started wilting. Birds stopped chirping. Even the mighty Sun started to flicker.

At last, the other gods had no choice. They turned their beloved Joe into stone, and trapped the Evil Spirit inside him. In the process, a part of the Evil Spirit escaped, and it still wanders around today, trying to seize power once again in the form of dreams.
