The story began when I my old computer had a problem with its motherboard, you know, its capacitors was leakage, so that my computer could not boot normally. I have tried to replace them with the same type, but nothing changed. So finally I decided to buy a new computer.

A new computer had higher spesification than before one, Although this computer was far from satisfaction. I did not have more budget for it. Here are the spesifications:

1. Processor: Intel Pentium D 940 @ 3200 MHz
2. Physical Memory: 2048 MB
3. Mainboard : Gigabyte 8I945GMF
4. Video Card : NVIDIA GeForce 6600
5. Physical Memory: 2048 MB
6. Hard Disk : ST3160023AS (160 GB)
7. DVD-Rom Drive : BENQ DVD DD DW1625
8. Chipset : Intel i945G/GZ

I installed Windows XP with service Pack 3. After installing Win XP and Installing all driver for motherboard I tried to connect my wireless USB adapter. I used usb adapter everytime I connected to internet, but now my USB adapter was not being recognized by system. Why did wireless USB adapter not recognized by system?, I used usb cable extension about 5 metre, but my friend also used usb cable extension about 12 metre, but their system could detect usb adapter.

To solve this problem I tried to cut usb cable (utp cable) by 1 metre, but my usb adapter still could not be detected, I tried to cut again by 1 metre for the 2nd time, also still got the same result.

I just had 3 metre USB cable now, but I needed to have at least 5 metre to get good signal from acces point (I placed USB adapter on the roof of my house).

I did not know why this happened? Then I asked my friend about this problem, and he told me how to solve this problem. I found that nothing is wrong with both usb adapter and cable, something is wrong with BIOS setting.

In the picture above we can see there are USB 2.0 controller option under Integrated Periperal. You can set Enabled or Disabled. When I faced this problem (wireless USB adapter not recognized) the option was set to Enabled. So I changed the option to Disabled then tried to reconnect the device, Yes my system could detect my wireless USB adapter now with 5 metre extension cable even when I changed to 12 metre.

You know that when we set option of USB 2.0 controller to Enabled, transfer data via USB port become faster than we set option to Disabled. When the option set to Disabled, USB ports have max power for device, so power lost by extension cable can be minimized.

I don’t have much time to find out USB-PS/2 adapter in the market, finally I asked my friend about this, he gave me wiring configuration for USB to PS/2 connector.

The wiring is very simple as the following:

USB Connector at the Mouse
Pin No 1 = VDC +5V
Pin No 2 = Data -
Pin No 3 = Data +
Pin No 4 = Ground

PS/2 Connector at the Mouse
Pin No 1 = Data
Pin No 2 = No Connect(NC)
Pin No 3 = Ground
Pin No 4 = VDC +5V
Pin No 5 = Clock
Pin No 6 = No Connect(NC)

Connect pin no.1 of USB to pin no.4 of PS/2.
Connect pin no.2 of USB to pin no.1 of PS/2.
Connect pin no.3 of USB to pin no.5 of PS/2.
Connect pin no.4 of USB to pin no.3 of PS/2.
PS: This wiring works only with mouse which supports with both interfaces (USB & PS/2).
Here are the result:

Many people learn programming language from book which they bought from bookshop or ebook which downloaded from internet in pdf files. Obviously, most of them learning using the old way, they look at the book or ebook then type the code line by line, I myself use this method before. Do you know this method is wasted so much time?, this method has very big weakness, as we know, sometimes there are any mistype what you see in the book or ebook with actual you typed.

I have a simple tip when learning programming language, after you downloaded ebook in pdf files, you should convert it into doc files. When you learn in this way you increase your productivity, so you use the time very effective, you never type anything code from the book which has potential mistyped, you can use copy and paste method from doc files which has converted from pdf files like pictures above. You can download free converter from www.hellopdf.com

2. 3-D Virtual Reality On Mobile Devices

3. Apple 2.0 The i-phone’s new Business Model

4. World’s Fastest Computer:It’s not super computer

New Blackberry with No keyboard:

(R.I.M.), the company that brought us the BlackBerry, has been on a roll lately. For a couple of years now, it’s delivered a series of gorgeous, functional, supremely reliable smartphones that, to this day, outsell even the much-adored iPhone.

R.I.M. hoped to soften the blow by endowing its touch screen with something extra: clickiness. The entire screen acts like a mouse button. Press hard enough, and it actually responds with a little plastic click.

As a result, the Storm offers two degrees of touchiness. You can tap the screen lightly, or you can press firmly to register the palpable click.

3-D Virtual Reality On Mobile Devices

If mere texting, talking, e-mailing and snapping pictures on mobile devices aren’t enough to satisfy your data cravings, now there’s the prospect of accessing and displaying 3-D virtual reality simulations and animations on them. New information architecture from researchers in Offenburg, Germany puts 3-D visualizations in the palm of your hand to make this possible.

Apple 2.0 The i-phone’s new Business Model

That’s the story about the new iPhone 3G that Apple is selling, and it’s a line that was echoed by Apple VPs and industry analysts in the Moscone West spin room after Steve Jobs’ keynote Monday.

“The new price point is a very big deal,” said Tim Bajarin of Creative Strategies. “With that, and the 70 countries, Apple is now a world player on the mobile smartphone stage.”

But it’s not that simple. There were a lot of financial details Jobs left out of his keynote that only emerged later in the day, in a 8-K form Apple (AAPL) filed with the SEC and a long press release issued by AT&T (T).

Apple alerted the SEC that although it had signed deals with 70 countries…

It means the iPhone has a new business model.

When the device was first introduced, Jobs was able to dictate some rather unusual terms. Customers had to pay full retail price for it (a practice almost unheard of in the mobile phone industry) and carriers had to share a sizable cut of their monthly revenue with the manufacturer (also virtually unprecedented).

Now, the carriers are subsidizing the cost of the phone, making up for it in monthly charges, and they are no longer funneling a share of that monthly revenue to Apple. As Piper Jaffray’s Gene Munster puts it: “Apple is basically playing by the rules that all other cell phone hardware manufacturers play by.”

Dell Increases revenue and earnings lowers operating expenses

Dell today reported record fiscal first quarter revenue of $16 billion, a 9% year-over-year increase, and earnings of $0.38 per share, a 12% increase.

The results were driven by better-than-industry growth of commercial and consumer products and services, and lower operating expense as a percent of revenue.

Product shipments in the quarter increased 22%, with servers growing three times the industry rate at 21%. Storage revenue increased 15% and enhanced services revenue was up 13%. Notebook unit growth, a Dell strategic priority, rose sharply at 43% and 1.2 times the industry growth rate. Consumer units grew at more than two times the industry rate and the company increased its global share by 1.2 points to 8.8% during the quarter.

“We are executing on all points of our strategy to drive growth in every product category and in every part of the world,” said Michael Dell, chairman and CEO. “These results are early signs of our progress against our five strategic priorities. Through a continued focus, we expect to continue growing faster than the industry and increase our revenue, profitability and cash flow for greater shareholder value.”

Paralysed man takes a walk in virtual world

A paralysed man using only his brain waves has been able to manipulate a virtual Internet character, Japanese researchers said Monday, calling it a world first.

The 41-year-old patient used his imagination to make his character take a walk and chat to another virtual person on the popular Second Life website.

The patient, who has suffered paralysis for more than 30 years, can barely bend his fingers due to a progressive muscle disease so cannot use a mouse or keyboard in the traditional way.

In the experiment, he wore headgear with three electrodes monitoring brain waves related to his hands and legs. Even though he cannot move his legs, he imagined that his character was walking.

He was then able to have a conversation with the other character using an attached microphone, said the researchers at Japan’s Keio University.

It is the first time a paralysis patient has succeeded in meeting a person and having a conversation in an Internet virtual world, they added.

Researchers are now studying a system that would let patients create text messages by mentally selecting certain letters, said Junichi Ushiba, associate professor at the biosciences and informatics department of Keio Universty’s Faculty of Science and Technology.

World’s Fastest Computer:It’s not super computer

A computer designed to run virtual tests of U.S. nuclear weapons will be the world’s fastest, making 1,000 trillion calculations per second, the U.S. Department of Energy said on Monday.
Roadrunner supercomputer at Los Alamos National Laboratory in New Mexico is the first to achieve a what is known as a petaflop of sustained performance, the department and IBM said.

“Flop” is an acronym meaning floating-point operations per second. One petaflop is 1,000 trillion computer calculations per second.

“Roadrunner will be used by the Department of Energy’s National Nuclear Security Administration to perform calculations that vastly improve the ability to certify that the U.S. nuclear weapons stockpile is reliable without conducting underground nuclear tests,” the department said in a statement.

“Roadrunner will not only play a key role in maintaining the U.S. nuclear deterrent, it will also contribute to solving our global energy challenges, and open new windows of knowledge in the basic scientific research fields,” it added.

“To put this into perspective, if each of the 6 billion people on earth had a hand calculator and worked together on a calculation 24 hours per day, 365 days a year, it would take 46 years to do what Roadrunner would do in one day,” the department said.
