Driving Directions from Eskişehir-to-Paris via Google Maps

Google Finally completed the way-direction support to Google Maps for Turkey.

Here is an example trip from Eskişehir to Paris.

This is why Google still #1.

You may find more detailed directions from here.

I’m curious about which shortest-path algorithm they use. When I find it, I hope, I will edit this post.

Samsung R522-XS08TR

Samsung R522-XS08TR

Two weeks ago, I bought one of this Samsung R522-XS08TR’s

I’m quite comfortable with it for now. Its 15.6″ wide-screen LCD is perfect for movies with a 16:9 aspect ratio. And also its display card is a ATI Mobility Radeon HD 4650 with an external 1 GB RAM (GDDR3) capacity and works good with latest computer games like Crysis, Half-Life 2 etc…

For me, Vista Home Basic operating system that comes with it is this computer’s only deficiency.

Here is all specs for this model;

CPU: Core 2 Duo P7350 2.0 Ghz – 3 Mb – FSB Speed: 1066 Mhz
Memory: 4GB DDR2 800 Mhz
HDD: 320GB  5400 RPM
Ports: 4 x USB, 1x e-SATA, 1 x VGA, 1 x HDMI, 1 x RJ-11, 1 x RJ-45, 1 x Audio output, 1 x Mic.
Max resolution: 1366 x 768
Battery type: Li-Ion 6 cell
Embedded web-cam

Surprising Science of Motivation

Of Not Missing The Point

In every subject, I think it is very important to catch the main point. When we start school, generally, cause of our teachers’ deficiencies or laziness, we are always ‘told’ something again and again but indeed not taught really. Yeah, there are really good teachers but they are always outnumbered. Because of that, we always make films and TV series about them.

Catching the main point is the key…

Let’s give an example about this;

We all know the equation;

We’re always said that this equation can be used when there is a triangle one of its angles is . The end! In this point, we’ve lost the point and a great good.

In reality, this pythagorean theorem can be used with any shape and for any formula that squares a number. Surprising, huh?

The area of any shape can bu computed from any line segment squared. Say a square (side 5, square 25) or a circle (radius 5, area 25*)

.

It can be a square, a rectangle, a triangle etc…

With same logic, this formula can be applied to any similar shape. All squares are similar ( ), same as all circles and same type of triangles.

Now, we may say;

Circle of radius 13 = circle of radius 5 + circle of radius 12 (Looks like 5-12-13 combination, huh?)

You may say, yeah it makes sense but it is still about geometry. What else?

Here it comes.

You know bubble-sort algorithm right? Its complexity is when there is input.

Using this equation, you can say;

50 inputs = 40 inputs + 30 inputs

which means 70 elements spread among two groups can be sorted as fast as 50 items in one group. (Yeah, there may be constant overhead/start up time).

Given this relationship, it makes sense to partition elements into separate groups and then sort the subgroups like quicksort. The Pythagorean theorem helps show how sorting 50 combined elements can be as slow as sorting 30 and 40 separate ones.

Interesting?

Reorganizing My Stuff

As I told earlier, I had decided to change my blog’s default language to English for non-Turkish visitors but when I start to organize my old posts, I realized that it’s not an easy job. Because there were a lot of categories and lots of rubbish entry in it. Instead of trying to organize them manually I’ve decided to create a new blog from scratch then I’ll copy my old but quality contents to new one from my old blog’s database backup.

So, please be patient and if you had read an entry and liked from my old blog please let me know about it then I will try to get it back here also.
