As I have been preparing my sermon series on the  Gospel of John I came across one theologian who said, "John's Gospel is simple enough a child can splash in it and deep enough an elephant can swim in it." That statement communicates what I believe God called Capshaw Baptist Church to be. The kind of place that will take you where you are and lead you to maturity in our Lord Jesus Christ. I believe that is what God called the Pastor/Teacher to in Ephesians 4 -

11. It was he who gave some to be apostles, some to be prophets, some to be evangelists, and some to be pastors and teachers, 12. to prepare God's people for works of service, so that the body of Christ may be built up 13. until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ.

My dream for Capshaw is that it is a place where a small child can come to know Christ and grow in his or her walk. I also want to be the kind of Church that would challenge a theologian continued sanctification and progression in the faith.

So many Churches seem to become the spiritual lid on the people only able to take them so far. The growing believer will find himself or herself bored and stagnated spiritually, unchallenged by the preaching and unmoved by the Spirit. Lord willing we will break that model and create something that will serve as a catalyst for growth at any level.

Недавно на форуме был поднят вопрос об использовании Send-SmtpMail.ps1 из скрипта который запускается в шедулере. Причем на сервере требуется аутентефикация, и соответственно необходимо использовать сохранённый пароль. Собственно с этим и возникла сложность.

Первая сложность - безопасность. Хранить пароль в расшифровываемом виде само по себе не очень безопасно, но это лучше чем хранить его открытым текстом. Решение этой проблемы я вобщем уже описывал в этом посте.

Вторая сложность в том что нам нужен не просто пароль, а объект типа Credentials, для передачи его в объект SmtpClient.

Короче говоря в результате получилось следующее решение:

Сначала под учетной записью того пользователя под которым будет запускаться скрипт выполняем следующий код:

Read-Host -Prompt "Enter password" -AsSecureString | ConvertFrom-SecureString | Set-Content password.txt

Будет запрошен пароль, который затем в зашифрованном виде будет помещён в файл password.txt. Причем для шифрования будет использован ключ текущего пользователя, то есть расшифровать его сможет тоже только он.

Теперь чтобы использовать пароль в скрипте, его сначала надо поместить в переменную типа SecureString. Делается это следующим образом:

$SecStr = Get-Content password.txt | ConvertTo-SecureString

Теперь в переменной $SecStr содержится зашифрованный пароль, расшифровывать его нам и не понадобится (то есть он даже в памяти не хранится в открытом виде). Нам нужно лишь создать на основе этого пароля и имени пользователя объект PSCredentials:

$c = New-Object System.Management.Automation.PSCredential("xaegrr",$SecStr)

Всё, теперь можно использовать:

Send-SmtpMail.ps1 -to $MyEmail -from $GmailMail -server smtp.gmail.com -SSL -Cred $c -Subject "Test passed"

Готово :) Разумеется в скрипте лучше всё таки указывать полные пути и к скрипту и к файлу с паролем.

Кстати, я обновил текст скрипта Send-SmtpMail.ps1, там почему то лежала старая версия, без поддержки SSL и учетных данных :( Сорри :(

"Perception is limited - always.

The challenge is not to perceive everything, it's to perceive what's important.

The primary tool of the propaganda system (also known as "the news media") is misdirection, having you pay attention to the wrong things.

One of the missions of Brasscheck TV is to provide you with key background information so that when you consume official propaganda (also know as "new reports") you realize there's more going on than what the news commentators are directing your attention towards.

This video is a fun demonstration of how this works in practice.

A simple website can easily go from nothing to a finished, published site in less than a day *if* you know what you're doing. Otherwise it can take weeks if not longer - and that assumes you get finished at all!

So in this article we're not just going to look at how to make a website, we're going to be more specific and consider how to make a website fast and easy so you can get your site online sooner rather than later.

Okay, well the good news is that with all the software and services around at the moment there is a greater chance to make a website fast and easy than ever before.

Let's take a look at some of the resources that will help you achieve this...

1) Wordpress

You can use Wordpress software free of charge to make a blog super-fast. Within minutes you'll have a basic website set up for you to tweak when you have time. Add some articles and you're done.

2) Blogger

Google's offering for bloggers offers a similar service to Wordpress though differs being easier to use but less fully-featured.

3) Nvu

Nvu free web design software lets you make a website easily on your home computer without splashing out cash.

4) Free Website Templates

Whether you decide to make a website from scratch using software like Nvu or using an online blogging solution like Wordpress or Blogger you will be able to find a host of free site templates that you can either use as-is , or modify to perfectly suit your needs.

A quick search in your favorite search engine will likely turn up hundreds of sites listing these template files.

5) CoolText

Allows you to create your own logo free of charge. Just visit the site, type in your website name, select the color, the font and so on and out pops your finished logo. What's more, they look great!

6) Royalty Free Images

Websites like IstockPhoto allows you to get royalty-free images to use on your website.

There is plenty of competition in the market now for web hosting. If you're wondering how to make a website fast and easy, then select a budget web hosting company to host your site. Then consider using Wordpress or Blogger to actually build a site, together with a free template to give it a professional look. You can be set up for under $5 a month with this solution, including your own website address.

The end result is fantastic and it's quick and easy to set up. This is my own personal favourite technique for making a website fast.

A photo from the family archives: I'm in the red snowflake hat.

"Where's your home?" It seems a simple question. I first heard it from a man who lived in a L'Arche community.

I've had lots of homes. I grew up in my parents' home, built just before I was born. I lived there for 21 years (not including time away at university). They are still living there, although my two brothers and I have moved away.

Then I moved. Three apartments in Saint John, one in Woodstock, then Oshawa, Newcastle and Orono. A house in Port Britain, then an apartment in Cobourg. We are now on our third apartment in Toronto, the best place yet.

Our current home in Toronto.

"Where's your home?" It's where my heart is, where my partner is, where my stuff, my memorabilia, my computer... where I can be myself. But that's not a place so much as an idea. It's wherever I happen to be living at the moment.

If there was one place I could call home, one place that I'm rooted in, no matter where I roam, I would have to say Saint John, where I grew up. I've lived in Ontario for nearly 20 years, but it's not really my home. When people ask, I tell them I live in Toronto, but I almost always add: I'm not from here; I'm a Maritimer. Some part of my heart will always be in that rocky sea-and-forest landscape that I associate with my childhood.

Saint John from the air.

One of the Maritime themes is that of people leaving -- for Toronto, Calgary, other places -- in order to find better jobs, better opportunities, a better life. Yet there's a second half to that story: a lot of Maritimers come home again, or at least they yearn to return.

I left that "home" a long time ago. I've heard people say "you can't go home again". But is it true? Or is it just that everything changes, that home is never the same again?

The people I grew up with have moved away or moved on with their lives. The paths I used to walk, the stores I used to visit are gone, overgrown or redeveloped. What I think of as "home" is a place in time, so in that sense, I can't go home. I can't go back.

And the fact is, I don't want to go back. I don't want to be an awkward teenager again, or return to that stage of my life when I was just beginning to discover my interests and develop a sense of myself. I like who I've become, my work and friends, being able to make my own way in the world.

Yet there's something else, some part of me that feels cut off, adrift. I felt that most keenly during my most recent visit, when my parents were celebrating their 50th wedding anniversary. I was surprised to see how many people I recognized, and how many people knew me and greeted me, not as a former acquaintance, but as family. Until then, I had only thought of home as geography, a mix of woods and houses, the cool blanket of fog drifting in off the coast, the steep road we bicycled to reach the blueberry patch under the power lines...

So where is my home? Is it really a place full of memories, the childhood I've left behind?

I wonder if there's more to that place than I had counted on, as if there's a future as well as a past. How would it feel for me, the confident grown-up me, to return to this place that still pulls at my heart? Maybe all these years I've been living in exile, and it's time to go home.

Where's your home?

I wonder how often we pack the big ideas, the major concepts in the standard, first with students. Do we lead off the unit with telling them about the standard? Do we instruct them directly on the big ideas?  Do we give them activities that clearly focus on the big ideas? Do we assess them on the big ideas?

I remember watching a teacher who did a half period introductory activity to the unit. The activity was engaging.  However, it did not deal with the big ideas of the unit but with a very minor point.

Do you pack the big ideas first with your students?

Education is probably the most important thing we all need to focus on in life. Not just for our kids, but for ourselves too. Knowledge is truly power, so get powerful! Feed yor head!

Saya akan tetap menggunakan editor sederhana seperti notepad dan melakukan semuanya secara manual. Mengapa tidak langsung pakai editor seperti Eclipse, Netbeans atau IDE canggih yang lain ?
Alasan pertama, karena ini akan membuat kita memahami "behind the scene things", yang merupakan fundamental dari Java, sehingga ketika kita menggunakan IDE yang canggih, kita sudah mengetahui, apa yang sebenarnya terjadi.
Alasan kedua, supaya saya bisa berbagi tentang eclipse atau netbeans di artikel berikutnya... Hehe, it's not a real reason friend :D

Tipe Data

Java mengenal 2 macam tipe data. Yang pertama adalah tipe data primitif, yaitu byte, short, char, int, long, float, dan double. Yang kedua adalah tipe data object. Ini adalah tipe yang dibuat dari definisi class. Root class di Java adalah class Object, semua class yang ada di library java maupun yang kita buat sendiri adalah turunan dari class Object.

Ok, mari kita mulai dengan membuat aplikasi Kalkulator. Direktori kerja saya saat ini adalah C:\Java. Buka notepad, kemudian ketik kode berikut (saya tetap berpendapat bahwa mengetik lebih baik daripada copy and paste).

[sourcecode language='java']
package suhearie.blog.morehelloworld;

public class Kalkulator {

public static void main(String[] args) {
if (args.length < 2) {
System.out.println("Penggunaan: java Kalkulator operand1 operand2");
}
else {
System.out.println("Hasil: 5");
}
}

}
[/sourcecode]

Kemudian lakukan langkah-langkah berikut:

1. Buat file source code. Save kode tersebut sebagai file source code dengan nama file Kalkulator.java. File source code harus memiliki extension .java dan harus sesuai dengan nama class utama, dalam hal ini Kalkulator.
2. Package adalah mekanisme pengelompokan source code. Karena saya menggunakan nama package suhearie.blog.morehelloworld, maka kita harus membuat struktur direktori yang mencerminkan package tersebut, dan meletakkan file source kita disana.
   
3. Compile source code. Buka command prompt, masuk ke direktori C:\Java, ketik
   javac suhearie/blog/morehelloworld/*.java. javac adalah compiler java. Jika kompilasi berhasil, javac akan menghasilkan file Kalkulator.class. Ini adalah file class (disebut juga bytecode) yang akan dieksekusi oleh Java Virtual Machine (JVM) pada saat runtime.
4. Jalankan aplikasi. Di command prompt, ketik java suhearie.blog.morehelloword.Kalkulator. Perintah ini akan menjalankan JVM dan mengeksekusi kode yang ada di dalam method public static void main(String[ ] args) { }. String[ ] args adalah variable bertipe string array untuk menampung argumen yang kita berikan saat memulai aplikasi.

Sejauh ini aplikasi kalkulator kita hanya melakukan print ke standard-output, ditambah logika sederhana untuk memeriksa apakah user sudah memasukkan dua argumen saat menjalankan aplikasi. Tapi hasilnya masih salah karena kita hanya menghasilkan nilai konstan tanpa memperdulikan input.

Saatnya mengimplementasikan perhitungan yang sebenarnya pada aplikasi ini. Saya melakukannya dengan:
1. Membuat constructor. Constructor adalah method spesial dalam sebuah class. Sesuai namanya, blok kode ini dipanggil untuk meng-construct object baru. Method ini tidak mempunyai return type, dan namanya harus sama persis dengan nama class.
2. Membuat method baru. Method tersebut bernama jumlahkan, tujuannya untuk menghitung jumlah dari dua buah input yang diberikan

[sourcecode language='java']
package suhearie.blog.morehelloworld;

public class Kalkulator {

public Kalkulator() {
System.out.println("Kalkulator baru saja dibuat");
}

private int jumlahkan(String operand1, String operand2) {
int x = Integer.parseInt(operand1);
int y = Integer.parseInt(operand2);
int hasil = x + y;
return hasil;
}

public static void main(String[] args) {
if (args.length == 2) {
Kalkulator myKalkulator = new Kalkulator();
int hasil = myKalkulator.jumlahkan(args[0], args[1]);
System.out.println("Hasil: "+hasil);
}
else {
System.out.println("Penggunaan: java Kalkulator operand1 operand2");
}
}

}
[/sourcecode]

Saatnya melakukan refactor, yaitu membuat code menjadi lebih reusable, agar kita bisa mendapatkan manfaat dari OOP. Kita akan membuat sebuah class baru yang bertugas sebagai "engine" untuk melakukan perhitungan.

Class KalkulatorEngine

[sourcecode language='java']
package suhearie.blog.morehelloworld;

public class KalkulatorEngine {

public int hitung(String operasi, String operand1, String operand2) {
int x = Integer.parseInt(operand1);
int y = Integer.parseInt(operand2);
if (operasi.equals("tambah")) {
return tambah(x, y);
}
else if (operasi.equals("kurang")) {
return kurang(x, y);
}
else {
System.out.println("Kalkulator tidak mendukung operasi "+operasi);
return 0;
}
}

private int tambah(int operand1, int operand2) {
return operand1 + operand2;
}

private int kurang(int operand1, int operand2) {
return operand1 - operand2;
}

}
[/sourcecode]

Integer.parseInt() adalah sintaks untuk mengubah dari String ke bilangan integer.

Class Kalkulator

[sourcecode language='java']
package suhearie.blog.morehelloworld;

public class Kalkulator {

private KalkulatorEngine engine = null;

public Kalkulator() {
System.out.println("Menyiapkan engine");
engine = new KalkulatorEngine();
System.out.println("Kalkulator baru saja dibuat");
}

private int hitung(String operasi, String operand1, String operand2) {
return engine.hitung(operasi, operand1, operand2);
}

public static void main(String[] args) {
if (args.length == 3) {
Kalkulator myKalkulator = new Kalkulator();
int hasil = myKalkulator.hitung(args[0], args[1], args[2]);
System.out.println("Hasil: "+hasil);
}
else {
System.out.println("Penggunaan: java Kalkulator operasi operand1 operand2");
}
}

}
[/sourcecode]

Di Class Kalkulator yang telah diperbaharui ini, kita tidak lagi melakukan perhitungan di dalam class ini. Kita meng-create sebuah object KalkulatorEngine, dan menyuruh engine ini untuk melakukan perhitungan.

Class Kalkulator yang sudah kita buat adalah aplikasi berbasis text. Sekarang kita akan membuat sebuah class baru yang berbasis Graphical User Interface (GUI). Library standard Java untuk membuat GUI adalah Swing dan AWT. Sebelum mendeklarasikan class, kita melakukan import terlebih dahulu dari library yang kita butuhkan untuk memberi tahu compiler, bahwa kita akan menggunakan class-class yang berasal dari library tersebut. Kali ini kita akan mengimport semua class dari package javax.swing dan package java.awt.event.

JFrame adalah class yang kita gunakan untuk membuat window di Java. Kita akan membuat class baru yang meng-extend class JFrame ini. Selanjutnya, kita masukkan semua komponen yang kita butuhkan yaitu, JLabel untuk label, JComboBox untuk dropdown box, JTextField untuk text box, dan JButton untuk tombol.

Setelah membuat GUI nya, kita menambahkan action listener pada komponen tombol, sehingga ketika tombol tersebut di-klik oleh user, kita bisa melakukan action yang kita inginkan, dalam hal ini memanggil engine untuk melakukan perhitungan dan menampilkannya pada kotak hasil.

Class KalkulatorGUI

[sourcecode language='java']
package suhearie.blog.morehelloworld;

import java.awt.event.*;
import javax.swing.*;

public class KalkulatorGUI extends JFrame {

private KalkulatorEngine engine;
private JComboBox comboOperasi;
private JTextField txtOperand1;
private JTextField txtOperand2;
private JButton btnHitung;
private JTextField txtHasil;

public KalkulatorGUI() {
System.out.println("Menyiapkan engine");
engine = new KalkulatorEngine();

System.out.println("Menyiapkan GUI");
setTitle("Kalkulator GUI");
setContentPane(createGUI());
setupAction();
setSize(600, 100);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

private JPanel createGUI() {
JPanel panel = new JPanel();

// Operasi
panel.add(new JLabel("Operasi"));
comboOperasi = new JComboBox();
comboOperasi.addItem("tambah");
comboOperasi.addItem("kurang");
panel.add(comboOperasi);

// Operand1
panel.add(new JLabel("Operand 1"));
txtOperand1 = new JTextField();
txtOperand1.setColumns(5);
panel.add(txtOperand1);

// Operand2
panel.add(new JLabel("Operand 2"));
txtOperand2 = new JTextField();
txtOperand2.setColumns(5);
panel.add(txtOperand2);

// Tombol Hitung
btnHitung = new JButton("Hitung");
panel.add(btnHitung);

// Hasil
panel.add(new JLabel("Hasil"));
txtHasil = new JTextField();
txtHasil.setColumns(5);
panel.add(txtHasil);

return panel;
}

private void setupAction() {
btnHitung.addActionListener(new MyActionListener());
}

class MyActionListener implements ActionListener {
public void actionPerformed(ActionEvent event) {
String operasi = (String) comboOperasi.getSelectedItem();
String operand1 = txtOperand1.getText();
String operand2 = txtOperand2.getText();
int hasil = engine.hitung(operasi, operand1, operand2);
txtHasil.setText(String.valueOf(hasil));
}
}

public static void main(String[] args) {
KalkulatorGUI kalkulator = new KalkulatorGUI();
kalkulator.setVisible(true);
}

}
[/sourcecode]

Anda akan mendapatkan tampilan seperti gambar berikut. Pilih operasi, masukkan operand 1 dan operand 2, kemudian tekan tombol Hitung, maka hasil perhitungan akan tampil di kotak hasil.

Disini kita dapat melihat keuntungan dari prinsip reusability, karena kita memiliki 2 aplikasi yang berbeda tapi menggunakan engine yang sama untuk melakukan perhitungan.

Ok, sekian untuk tutorial kali ini. Silahkan review kembali kode yang sudah kita buat untuk lebih memahami bagaimana kode tersebut bekerja. Selamat belajar !!
