Langkah-langkah Instalasi SQL Server 2008 Enterprise

Berikut ini file tutorial instalasi SQL Server 2008 Enterprise yang saya buat dalam bentuk file *.doc :

Delete File Recursively In Linux

 

Find all files having .bak (*.bak) extension in current directory and remove them:
$ find . -type f -name "*.bak" -exec rm -f {} \;

Find all core files and remove them:
# find / -name core -exec rm -f {} \;

Find all *.bak files in current directory and removes them with confirmation from user:
$ find . -type f -name "*.bak" -exec rm -i {} \;

Bioinformatika

Bioinformatika adalah ilmu yang mempelajari penerapan teknik  komputasional untuk mengelola dan menganalisis informasi biologis. Bidang ini mencakup penerapan metode-metode matematika, statistika, dan informatika untuk memecahkan masalah-masalah biologis, terutama dengan menggunakan sekuens DNA dan asam amino serta informasi yang berkaitan dengannya. Contoh topik utama bidang ini meliputi basis data untuk mengelola informasi biologis, penyejajaran sekuens (sequence alignment), prediksi struktur untuk meramalkan bentuk struktur protein maupun struktur sekunder RNA, analisis filogenetik, dan analisis ekspresi gen.

Saat ini, perkembangan ilmu biologi sangat dipengaruhi oleh perkembangan ilmu bioinformatika. Tidaklah dapat dimungkiri kalau bioinformatika telah mempercepat kemajuan ilmu biologi. Lebih jauh lagi, kalau dilihat dari bidang yang lebih spesifik, kemajuan suatu bidang sangat dipengaruhi oleh kemajuan bioinformatika. Semakin maju bioinformatika di suatu bidang (ditandai dengan banyaknya software yang tersedia), semakin maju pulalah bidang tersebut.

Kemampuan Komunikasi bagi Lulusan IT

Komunikasi adalah suatu proses penyampaian pesan (ide, gagasan) dari satu pihak kepada pihak lain agar terjadi saling mempengaruhi diantara keduanya. Pada umumnya, komunikasi dilakukan dengan menggunakan kata-kata yang dapat dimengerti oleh kedua belah pihak. Melalui komunikasi, sikap dan perasaan seseorang atau sekelompok orang dapat dipahami oleh pihak lain. Akan tetapi, komunikasi hanya akan efektif apabila pesan yang disampaikan dapat ditafsirkan sama oleh penerima pesan tersebut

Selain itu dalam kehidupan sehari-hari, komunikasi yang baik sangat penting untuk berinteraksi antar personal maupun antar masyarakat agar terjadi keserasian dan mencegah konflik di lingkungan masyarakat. Sebaliknya, apabila terjadi kesalahan dalam salah satu proses komunikasi akan menyebabkan tidak tercapainya tujuan yang ingin dicapai. Oleh karena itulah komunikasi menjadi sangat penting bagi kehidupan kita.

XNA – TriangleStrip

The idea behind TriangleStrips is that you should define each vertex only once. So for the first triangle, you have to define vertices 0,1 and 2. Now, for the next triangle, you only have to add vertex 3, XNA will always use the last 3 vertices to draw the triangle, so for the second triangle it uses vertices 1, 2 and 3, which is correct.

C# Preprocessor

These commands never translated and included into the executable file but these are very useful for compilation process. Using preprocessors, we can stop the compiler from compiling certain potion of code. This is very helpful in the situation where you are planning to release two versions of software one basic version which has less features and one advance version which has more features. The preprocessor directives are all starts with the # symbol in the beginning of them.

C# actually has almost all the standard preprocessor directives – it just happens to be that the functionality of some of them . The one notable directive that is missing is #include – and it makes sense that C# wouldn’t have it, because C# gets the same sort of functionality from the using statements (although there is the fact that #include refers to files and using refers to assemblies – so they are definitely not equivalent).

Rules

1. Preprocessor directives must be on separate line
2. Must not terminate with semicolon compared to normal C# statements
3. Starts with # character
4. End of line comments are not allowed
5. Delimited comments are not allowed

XNA – Quaternion

The XNA Framework provides the Quaternion structure to represent and calculate the efficient rotation about a vector around a specified angle. Quaternions represent a rotation. Typically, they are used for smooth interpolation between two angles, and for avoiding the gimbal lock problem that can occur with euler angles.

A Quaternion is much like a Matrix, but can only store a rotation. Don’t let the name of this thing scare you away (for first time i hear it, i thinks it is a weird planet’s name ), although it’s very hard to understand mathematically (it makes my head blown away) a quaternion is VERY very easy to use.

In this tutorial, we will create a simple example program using quaternion, we will draw a spacecraft and it would be flying through 3D world.

Linux Mint 7 Video Installation

Just a video about Linux Mint 7 Installation.

Well, Linux Mint 7 is a great Distro

XNA – Camera Rotation

In this article, we will create a simple XNA program that load a 3D model, and rotating the camera around the model. In this example,  showing how to moving your camera position around the model. Camera target and camera up vector will remain same, what we need is to change camera position vector.

XNA – Using Effect

The XNA Content Pipeline is pretty good. It implifies the process for importing and loading models, textures, and other content. Unfortunately, it is optimized for loading data, not code. Effect files are essentially code, so an alternative approach could provide additional benefits.

Like the XNA Content Pipeline, Effect Generator compiles your .fx files at build time, reducing game load times. Additionally, Effect Generator further simplifies run-time loading and effect parameterization.

Place your effect file in Content folder :

We start by declaring an Effect:

Effect effect;

We’ll use the Content pipeline to load an instance of the Effect class:

effect = Content.Load<effect>("effects");

And render using the effect:

effect.CurrentTechnique = effect.Techniques["Pretransformed"];
effect.Begin();
foreach (EffectPass pass in effect.CurrentTechnique.Passes)
{
    pass.Begin();

    pass.End();
}
effect.End();
