Solo Guitar Style

Ada 3 style solo gitar yang gw suka. 

Sebetulnya, masih banyak lagi style lainnya dan mungkin style baru akan terus bertambah seiring perkembangan zaman.

1. Classic

Menurut gw, gitar klasik merupakan fundamental / basic penting buat belajar ke gaya lainnya. Buat yang udah bisa klasik, pasti cukup mudah untuk belajar gaya lainnya.

Jadi, gw menyarankan buat yang mau belajar gitar, sebaiknya coba ambil klasik lebih dulu.

Walaupun nanti ketika belajar klasik, mungkin merasakan kebosanan tinggi karena lagu-lagu klasik yang kurang dikenal dan teknik tertentu yang sulit dikuasai. Kuncinya adalah jangan cepat menyerah, terus latihan.
Pada nantinya lo akan merasakan justru di situlah enaknya balajar gitar klasik, banyak tantangannya.

The Hobbit - An Unexpected Journey

The Hobbit menceritakan Bilbo Baggins, seorang hobbit yang awalnya anti-sosial karena terlalu nyaman dengan hidupnya.

Tapi, semua hidupnya berubah setelah kedatangan Gandalf (penyihir) yang diam-diam mengundang teman-temannya untuk pesta di rumah Bilbo Baggins.

Gandalf mengajak Bilbo bergabung dengan teman-temannya (yang "brutal" dan sebagian bodoh) untuk berpetualang mengalahkan Smaug (naga). Akhirnya Bilbo mau bergabung dengan Gandalf dan disinilah kehidupan baru Bilbo Baggins dimulai.

Sebenarnya, kisah The Hobbit terjadi 60 tahun sebelum Lord of The Ring.
Dalam The Hobbit, Bilbo Baggins akan menemukan cincin dari goblin yang nantinya akan diwariskan kepada Frodo di kisah Lord of The Ring.

The Hobbit juga dibuat dengan efek visualisasi yang mengagumkan, apalagi film ini juga rilis dengan versi 48 frames per second (2x kecepatan normal).Selain itu, tingkah laku Bilbo Baggins yang lucu dan tidak terduga membuat film ini menjadi menarik.

Menurut berita, The Hobbit akan dibuat trilogi yang edisi terakhirnya akan dirilis pada tahun 2014 dan edisi keduanya akan dirilis bulan Desember 2013 (masih lama yah....).

"Remember... true courage is about knowing not when to take a life, but when to spare one."- Gandalf

How To Solve Problem In Your Sleep

As a human, we usually encounter problems in our life.
As we can see, in 21th Century many people stress because of their problems.

They have no time to solve all of the problems. If you cannot solve your problems, you will be stressed.
So, problem solving is the important ability in our life.

We spend almost a third of our lives to sleep and almost a third of that time we dreaming.
Maybe sometimes you realize that during sleep, dreams can offer solutions to your problems.

Dreams can especially helpful for problems that require creativity of visualization to solve. When you fall asleep, you enter an alternative state of consciousness, a time when true inspiration can strike.

Actually, the act of dreaming is simply thinking about our usual concerns in a different state of consciousness.
By thinking about specific problems before go to bed, we can increase our chances that we will dream a solution.

How can we do it?

1. Write down your problem as a brief sentence and place this note next to your bed.
2. Review the problem for a few minutes before going to bed.
3. Once in bed, visualize the problem as a concrete image.
4. Tell yourself you want to dream about the problem as you drift off to sleep.
5.  On awakening, note whether you recall any trace of a dream (try to invite more of the dream to return).
6.  Try to arrange objects that connected to the problem.

In a short amount of time, you can learn to focus your dreams on minor problems and often solve them.

7. DirectAccess: A VPN Without the Pain of a VPN
8. Dynamic Access Control: New Way of Thinking
9. Resilient File System: An Evolution of NTFS
10. Out-of-the-Box IP Address Management

b.Linux

Linux is an open source Operating System. Linux also is a multipurpose operating system. So, Linux is it can be installed on a wide variety of computer hardware, ranging from mobile phones, tablet computers and video game consoles, to mainframes and supercomputers.  Thus some network servers use Linux as their operating system. 

With Linux, a network administrator can configure the network, administer security, run a Web server, and process e-mail. Clients on the network can run Linux, UNIX, or Windows.

Operating System in Mobilephones

a.Iphone OS 6

Iphone OS 6, developed by Apple Inc. is an operating system for iPhone and iPod touch, With the iPhone OS, users can manage contacts and notes, send and receive e-mail and text messages, take pictures, record videos, record voice messages, view a compass, connect to the Internet wirelessly and browse the Web, check stocks, access maps and obtain directions, listen to music, watch movies and videos, and display photos. 

It also provides Wi-Fi access to the iTunes Music Store.

b.Android

Android is a Linux-based operating system designed primarily for touchscreen mobile devices such as smartphones and tablet computers. Android OS is designed by Google Inc. it’s used on more 20 different types of smartphones.

Android OS allows programmers to design programs specifically for devices supporting this operating system. Android OS contains features such as access to e-mail accounts, an alarm clock, video capture, access to Google Apps, Wi-Fi access, and easy Web browsing.

The Android OS is, in strictly legal terms, open source. Android is released under the Apache 2.0 software license, which allows anyone to use, modify and redistribute the code. But while it might meet the letter of the law, Android falls short on the other two points.

In the software world, “open” can be defined around three core traits: a license that insures the code can be modified, reused and distributed; a community development approach; and, most importantly, assurance the user has total freedom over the device and software.

It’s the lack of community-based development that Android’s critics say makes it no more “open” than Apple’s locked-down, decidedly not-open iOS model.

Unlike major open source projects like Firefox or the Linux kernel, you can’t see what’s happening behind the scenes with Android, nor can small developers contribute to the project in any meaningful way. Google typically releases major updates to Android at press conferences, not unlike those Apple uses to show off new iPhone features.

Once the code is released, Android developers can download it and do what they want with it, but they have no way of seeing what’s happening behind the scenes every day.

Funny Explanation of Programming Language

I just found a funny explanation kinds of programming language in human language.
Understandable and interesting because there is a sense of humor in the explanation.

PHP is your teenage sweetheart, the girl you first awkwardly fumbled around with that one summer. Just don't try and start a more serious relationship - this girl has serious issues.

Perl is PHP's older sister. She might be a bit old for you, but she was pretty popular back in the 90s. She's looking pretty ugly and scarred now, so you don't hear from her too much.

Ruby is the cool kid of the scripting family. When you first saw her, she took your breath away with her beauty. She was fun, too. At the time she seemed a bit slow and ditzy - though she's matured a lot in the last few years.

Python is Ruby's sensible (and slightly more boring) sister.

Java is a successful career woman. What she lacks in raw intelligence she makes up for in dress - always turned out in immaculateCamelCase, sure to impress the enterprise customers. You might feel like she's the sensible type you should settle down with. Just prepare for years of "NO THAT DOESNT GO THERE GOD YOU ALWAYS USE THE WRONG TYPE AND YOU MISSED A SEMICOLON" nagging.

C++ is Java's cousin. Similar to Java in many ways, the main difference being she grew up in a more innocent time and doesn't believe in condoms/automatic memory management, so be cautious.

C is C++'s mom. Mention her name to some old grey beard hackers and they're sure to reminisce with a twinkle in their eye.

Objective C is another member of the C family. She joined that weird church a while back, and won't date anyone outside of it.

Haskell, Clojure, Scheme and their friends are those hipster, artsy, intellectual girls you probably spent a blissful college summer with a few years ago. The first girls who really challenged you. Of course, it could never have become something more serious (you tell yourself). Though you'll always be left asking "what if?"

You might be put off C# due to her family's reputation. But they've gone legit, the last few years, they tell you. Once you're one of us, you're one of us, you hear? You need a database? Her brother MSSQL will hook you up. Need a place to stay? Heck, her daddy will even buy you your own mansion on Azure avenue. What's that, you're having second thoughts about all these overly friendly relatives? No, you can never leave. You're part of the family, now, ya hear?

Javascript - hey, wasn't that the girl you first kissed, way before even PHP came on the scene? I wonder what she's doing now. I hear her career's really taken off in the last few years. Would be cool to catch up some time, if only for old time's sake... (You catch sight of her, dressed head to toe in designer jQuery)... wow,somebody grew into a beautiful swan...

Hope you like it ! :)

Short Answer

1. What are three different types of mouse devices?

Three different types of mouse devices are mechanical, opt. mechanical, and optical.

- What makes them different from each other?

Mechanical: Has a rubber or metal ball on its underside that can roll in all directions. Mechanical sensors within the mouse detect the direction the ball is rolling and move the screen pointer accordingly.

Opt. mechanical: Same as a mechanical mouse, but uses optical sensors to detect motion of the ball.

Optical: Uses a laser to detect the mouse's movement. You must move the mouse along a special mat with a grid so that the optical mechanism has a frame of reference. Optical mice have no mechanical moving parts. They respond more quickly and precisely than mechanical and optomechanical mice, but they are also more expensive.

2. Name at least five mouse operations.

Single-click, Double-click, Triple-click, Drag, right click

- Describe and give examples of each of the mouse operations

that you chose.

Single-click: clicking the main button.

Ex: The user click left / right mouse button to any object on desktop.

Double-click: clicking the button two times in quick succession counts as a different gesture than two separate single clicks.

Ex : When you want to open an application, you do double click on the icon of that application.

Triple-click: clicking the button three times in quick succession.

Ex: If you want to block all words in one sentence, try to do triple click.

Drag: pressing and holding a button, then moving the mouse without releasing.

Ex: Block a paragraph by holding the right click and moving the mouse without releasing (drag)

Right-click: clicking the secondary button.

Ex: You do this when you want to see the optional features of any application (properties).

3. What is OCR (optical character recognition)?

Optical Character Recognition (OCR) is a technology that involves reading typewritten, computer printed, or hand-printed characters from ordinary documents and translating the images into a form that the computer can process.

- What is OMR (optical character recognition)?

Optical Mark Recognition (OMR) is a technology that reads hand-drawn marks such as small circles or rectangles.

4. What is the most widely used biometric device today?

The most widely used biometric device today is fingerprint reader.

- Describe how the device works.

A fingerprint reader, captures curves and indentations ofa fingerprint to identify whether the ‘inputted’ fingerprint are the right one.

5. What is the Americans with Disabilities Act (ADA)?

 Americans with Disabilities Act are rules for company with 15 or more employees to make a reasonable attempt to accommodate the need of physically challenged workers.

- How might gesture recognition and computerized implant devices help physically challenged users in the future?
Gesture recognition and Computerized implant devices are a way for human to provide a natural computer interface for the physically challenged people through a means of just moving a small part of the body that are still functioning.
