Stress for Computer Programmers
What is a stress?
Stress is the consequence of the failure to adapt to change, specifically the inability to respond appropriately to emotional or physical threats to the organism, whether actual or imagined.[1] Common stress symptoms include irritability, muscular tension, inability to concentrate and a variety of physical reactions, such as headaches and accelerated heart rate.http://en.wikipedia.org/wiki/Stress_(medicine)
What are the sources of stress?
According to my officemates here are the sources of stress.
1. Boyfriend/girlfriend. ( demanding partners)
2. Family ( if you are a breadwinner of the family)
3. Tax (deductions to your salary every payday is too much because of your tax)
4. Deadlines (meeting your deadlines)
5. Sourcecode, Bug(for programmers)
6. Specs ( client specs, what they want to add in the next release)
7. Release ( release of product that are not yet tested)
8. Neighbors ( noisy neighbors)
9. Clients/ Customers ( customers are always right)
10. Financial Status
What are the ways to relieve your stress?
1. Playing PSP or computer games.
2. Watching funny videos in youtube
3. Go to starbucks and buy coffee.
4. Go to some bar and drink alcoholic drink but not too much because it can cause you another stress.
5. Sing your favorite song in a loud voice..
6. etc..
Here’s a another interesting article titled “Memo to my Managers”.. It was forwarded by my friend..
Memo to my Managers – the ‘Rules’…
1.Never give me work in the morning. Always wait until 4pm and then bring it to me. The challenge of a deadline is refreshing.
2.If it’s a really rush job, run in and interrupt me every 10 minutes to enquire how it’s going. That helps. Or even better, hover behind me, advising me at every keystroke.
3.Always leave without telling anyone where you’re going. It gives me a chance to be creative when someone asks where you are.
4.If my arms are full of papers, boxes, books or supplies, don’t open the door for me. I need to learn how to open doors with no arms in case I should ever be injured and lose all use of my limbs.
5.If you give me more than one job to do, don’t tell me which is the priority. I am psychic.
6.If a job I do pleases you, keep it a secret. If that gets out it could mean a promotion for me.
7.On the other hand, if you don’t like my work, tell everyone. I like my name to be popular in conversations; I was born to be whipped.
8.If you have special instructions for a job, don’t write them down. In fact, save them until the job is almost done. No use confusing me with useful information.
9.Never introduce me to the people you’re with. I have no right to know anything. In the corporate food chain, I am plankton. And anyway, when you refer to these people later, my shrewd powers of deduction will identify them.
10.Be nice to me only when the job I’m doing for you could really change your life and send you straight to manager’s hell.
11.Tell me all your little problems. No one else has any and its nice to know someone is less fortunate. I especially like the story about you having to pay so much tax on your salary.
12.Wait until my yearly review and THEN tell me what my goals SHOULD have been or what I did wrong eight months ago. Give me a mediocre performance rating, or better still, keep postponing the review meeting. I’m not here for the money anyway.
Learning PHP…
PHP (recursive acronym for “PHP: Hypertext Preprocessor”) is a widely-used Open Source general-purpose scripting language that is especially suited for Web development and can be embedded into HTML.
Example 1: Hello World (sample1.php)
<html>
<head>
<title>Example</title>
</head>
<body>
<?php
echo "Hi, I'm a PHP script!";
?>
</body>
</html>
PHP can be used on all major operating systems, including Linux, many Unix variants (including HP-UX, Solaris and OpenBSD), Microsoft Windows, Mac OS X, RISC OS, and probably others. PHP has also support for most of the web servers today. This includes Apache, Microsoft Internet Information Server, Personal Web Server, Netscape and iPlanet servers, Oreilly Website Pro server, Caudium, Xitami, OmniHTTPd, and many others. For the majority of the servers PHP has a module, for the others supporting the CGI standard, PHP can work as a CGI processor.v
Variables and Operators
$var = “Hello”; //string “hello”
$var = 3; // integer 3
$var2 = $var1; // Assigns a value of ‘PHP’ to $var2
echo $var1; // Outputs ‘PHP’
STRINGS
A string is series of characters. In PHP, a character is the same as a byte, that is, there are exactly 256 different characters possible.
<?php
echo “Hello World”;
?>
ARRAYS
An array is a special kind of variable that contains multiple values. The simplest way to create an array in PHP is to use the built-in array function:
$myarray = array(‘one’, 2, ‘3’);
$arrayvar = array(‘apple’, ‘banana’, ‘orange’);
echo $arrayvar[0]; // Outputs ‘apple’
echo $arrayvar[1]; // Outputs ‘banana’
echo $arrayvar[2]; // Outputs ‘orange’
CONTROL STRUCTURES
The most basic, and most often-used, control structure is the if-else statement.
Here’s what it looks like:
1. If condition
Ex: if($username==”admin” and password==”admin”) { echo “Hello admin! Welcome!”; }
else { echo “Invalid username or password”; }
2. While condition
Example:
$count = 1;
while ($count <= 10) {
echo “$count “;
++$count;
}
3. For Loop
Ex: for($i = 0; $i <10; $i++)
{ echo $i; }
Example:
<html>
<body><center>
<table width =”50″ border=”1“>
<?php
for($y=1; $y<=10; $y++)
{ echo “<tr><td><center><h1>$y </h1></center></td></tr>”; }
?>
</table>
</center>
</body></html>
DEALING WITH FORMS
One of the most powerful features of PHP is the way it handles HTML forms. The basic concept that is important to understand is that any form element in a form will automatically be available to your PHP scripts.
welcome.html
<form action=”welcome.php” method=”get”>
<label>First Name: <input type=”text” name=”firstname” />
</label><br />
<label>Last Name: <input type=”text” name=”lastname” />
</label><br />
<input type=”submit” value=”GO” />
</form>
welcome.php
<?php
$firstname = $_POST[‘firstname’];
$lastname = $_POST[‘lastname’];
echo “Welcome to my Website, $firstname $lastname!”;
?>
SESSION HANDLING FUNCTIONS
Session support in PHP consists of a way to preserve certain data across subsequent accesses. This enables you to build more customized applications and increase the appeal of your web site.
A visitor accessing your web site is assigned an unique id, the so-called session id. This is either stored in a cookie on the user side or is propagated in the URL.
Example:
session_start();
$_SESSION[‘username’] = $name;
To destroy a session you created:
Example: session_destroy();
UPLOADING FILE IN PHP
The <input type="file"> form element lets a user upload the entire contents of a file to your server. When a form that includes a file element is submitted, the PHP interpreter provides access to the uploaded file through the $_FILES auto-global array.
$_FILES[‘upload-name’][‘name’]: The name of the file as uploaded from the client to the server.
$_FILES[‘upload-name’][‘type’]: The MIME type of the uploaded file. Whether this variable is assigned depends on the browser capabilities.
$_FILES[‘upload-name’][‘size’]: The byte size of the uploaded file.
$_FILES[‘upload-name’][‘tmp_name’]: Once uploaded, the file will be assigned a temporary name before it is moved to its final location.
$_FILES[‘upload-name’][‘error’]: An upload status code. Despite the name, this variable will be populated even in the case of success. There are five possible values:
CONNECTING PHP TO MYSQL
1. $connect = mysql_connect(address, username, password); // address is the ip address or host name of the computer. username and password of the same username and password of your mysql server. returns true if the connection is established.
2. mysql_select_db($databasename,$connect); // databasename name of the database, $connect is the name of the connection your established see no.1.
3. mysql_query($query[, connection_id]); // $query is the sql command you want to execute;
4. mysql_close([connection id]) // To close the connection in database server.
Example:
<?php
$link = mysql_connect(‘localhost’, ‘root’, ”);
if (!$link) {
die(‘Could not connect: ‘ . mysql_error());
}
echo ‘Connected successfully’;
mysql_close($link);
?>
Greedy Relative…
How can you define greedy ? “well in my case, these are the people who were allowed to BORROW a property which they didn’t pay any amount for to the owner and the government, yet without etiquette and without word of honor, they deliberately refused to remove their belongings in the time due for them to move out. ” Building their house is only permitted by the owner. But the garage is too much. But because the owner is too kind, he asked that greedy person to sign a contract that if he wants to get that piece of land pertaining to the garage he can get that without any problem.. Years passed, the owner decided to get that piece of land because he wants to build a small office in that space.. Because they refused to remove their garage, the owner filed a case against his relative. But the greedy relative also filed a case of human rights..
“Human rights? WHAT A SHAMELESS PEOPLE? How could they file a violation of human rights! To my knowledge, the violation done is them COVETING OUR PROPERTY and AND ABUSING OUR GENEROSITY! The owner, of course, never failed to spend so much on the maintenance of that lot and these greedy people only covet it!
That’s not only a sin against society but also violates God’s commandment “thou shall not covet thy neighbors property”
Plus, it is also a form of stealing!
According to republic act no 386:

Simple HttpServer in Twisted Python
this is a sample code of http server programmed in twisted python
#httpserver.py
#!/usr/bin/python
import sys
from twisted.protocols import basic
from twisted.web import server,resource,http
from twisted.internet.protocol import Protocol
class HttpProtocol(basic.LineReceiver,Protocol):
def __init__(self):
self.lines = []
def connectionMade(self):
self.sendLine(“HTTP/1.0 200 OK”)
self.sendLine(“Content-Type:text/plain”)
self.sendLine(“”)
def lineReceive(self,line):
# your code goes here: process the line you receive
print line
class HttpFactory(http.HTTPFactory):
def __init__(self):
self.protocol = HttpProtocol
def onClientConnected(self):
print “Connected”
reactor.listenTCP(8080,HttpFactory())
reactor.run()
running on the terminal
$ python httpserver.py
as the reactor.run called, your http server is now listening on port 8080

Send Message in J2ME
Sample code for sending a message using J2ME: You can send message with or without port.
MessageConnection smsconn = null;
try {
/** Open the message connection. */
smsconn = (MessageConnection)Connector.open(address);
TextMessage txtmessage =
(TextMessage)smsconn.newMessage(MessageConnection.TEXT_MESSAGE);
txtmessage.setAddress(address);
txtmessage.setPayloadText(messageBox.getString());
smsconn.send(txtmessage);
} catch (Throwable t) {
t.printStackTrace();
}
if (smsconn != null) {
try {
smsconn.close();
} catch (IOException ioe) {
System.out.println(“Closing connection caught: “);
ioe.printStackTrace();
}
}
Start the Midlet when New Message arrived
If you want your midlet to start when incoming message arrived, the message should be sent with specific port where your midlet is listening.
Your jad file should look like this
MIDlet-Jar-URL: MyMidlet-0.0.1.jar
MIDlet-Jar-Size: 556255
MIDlet-Name: MyMidlet
MIDlet-Vendor: 3rd Brand Pte Ltd.
MIDlet-Version: 0.0.1
MIDlet-1: com.MyMidlet
MIDlet-Push-1: sms://:5000,MyMidlet,*
MIDlet-PortNumber: 5000
MIDlet-Permissions: javax.microedition.io.PushRegistry,javax.wireless.messaging.sms.receive
But your midlet does not automatically start when new message arrive.. It will ask you if you want to start your midlet.
Writing J2ME Application in Linux
If you’re going to create a mobile game application better use j2me.. But if you’re mobile application runs in a background better used symbian c++.
Quick Start for setting up your workspace..
1. Install eclipse in synaptic manager for your IDE. Why choose eclipse? Simple and easy to use.
2. You need to have the Java Development Kit (JDK) and the Sun Java Wireless Toolkit (WTK) installed on your system. Click here for installation tutorial
3. Install JDK Sun Java Standard Edition (SE) Downloads .
4. After setting up all the installers, you can now create a simple Hello World.
Creating a project:
1 Choose File – > New -> Project
2. New Poject window will appear. Select J2ME Midlet suite then click Next. Type the name of your project. Example HelloWorld Select which Device your going to use. Then click Finish.
3. On the project explorer pane, right click the name of your project.Select New – > Package. Type the name of your package.
4. After creating a package, right click it, select New -> File . Type your filename for example “HelloWorld.java”
Type this source code.
Create the file src/HelloWorld.java with the following code:
// Sample adapted from http://developers.sun.com/mobility/midp/articles/wtoolkit/
package com.hello
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
public class HelloWorld
extends MIDlet
implements CommandListener
{
private Form mMainForm;
public HelloWorld()
{
mMainForm = new Form(“HelloWorld”);
mMainForm.append(new StringItem(null, “Hello, World!”));
mMainForm.addCommand(new Command(“Exit”, Command.EXIT, 0));
mMainForm.setCommandListener(this);
}
public void startApp()
{ Display.getDisplay(this).setCurrent(mMainForm); }
public void pauseApp() {}
public void destroyApp(boolean unconditional) {}
public void commandAction(Command c, Displayable s)
{ notifyDestroyed(); }
}
5. You can now run your HelloWorld midlet.
6. Creating the jar file. Right click the name of your project . Select J2ME then Create Package..
Keep Moving Forward
The first lesson in my work.. Keep Moving Forward..
The incident happened when I checked- in the svn ( svn commit -m”checkin tester program”). By the way, what is svn/ subversion? “Subversion is used for version control when developing a program or system. It helps to keep track of your versions”. I used the copy for different program. When I checked-in my project, I forgot that there is hidden folder .svn. The backup copy is also updated and the tags are broken.. What a big mistake I have done. I’mm afraid that it can damage the working copy in our trunk.. My boss told me that it’s ok to make a mistake, at least you learned. He also told me about the movie “Meet the Robinsons” and lesson on this movie is “Keep Moving Forward”.. Thanks to svn.. It can revert the working copy..
The Explosive One
