Memberi makanan/minuman adalah salah satu bentuk sadaqah jariyah, yang amal pahalanya akan terus mengalir selama yang kita sedekahi masih hidup dan melakukan kebaikan.
Program sedekah nasi gratis adalah model sedekah yang unik, dimana dalam satu tempat, siapapun boleh memberi sedekah nasi/minum/snak dan siapapun juga boleh mengambilnya. Saat ini, gerai nasi gratis sudah tersedia di beberapa tempat (Piyungan, Bekasi, dan lain-lain). Untuk anda yang dekat dengan gerai, silakan langsung meletakkan makanan/minuman/snack di gerai nasi gratis.
Untuk anda yang jauh atau tidak sempat mampir ke gerai, anda dapat menyalurkan sedekah nasi gratis anda melalui sahabatkebaikan di tautan berikut.

<p>BigHybrid is a simulator based on SimGrid, used to simulate MapReduce under Hybrid environment (Desktop Grid and Cloud environment). Followings are the steps to install</p>
<ul>
<li>BigHybrid needs <code>SimGrid</code> version 3.14.159. Download the zip from this link: https://github.com/simgrid/simgrid/archive/v3<em>14</em>159.zip</li>
<li>Install some packages needed: <code>libboost-dev libboost-context-dev</code></li>
<li>Extract the zip. It will be easier if you use <code>unzip</code>. Just install it using the following command: <code>sudo apt-get install unzip</code></li>
<li>Install the simgrid</li>
</ul>
<div><pre><code class="language-none">cd simgrid-3_14_159
cmake -DCMAKE_INSTALL_PREFIX=/opt/simgrid .
make
make install</code></pre></div>
<ul>
<li>Now download and install BigHybrid</li>
</ul>
<div><pre><code class="language-none">wget https://github.com/Julio-Anjos/Bighybrid/archive/master.zip
unzip master.zip
cd BigHybrid</code></pre></div>
<ul>
<li>Change the <code>INSTALL_PATH</code> in <code>Makefile</code> and <code>examples/Makefile</code>. Point to the folder where you put the SimGrid. In my case, my <code>INSTALL_PATH</code> is like this: <code>INSTALL_PATH = /home/arwan/simgrid-3_14_159</code>. You can do this by using any editor you like. In my case, I love <code>nano</code>. I did this to edit: <code>nano Makefile</code> and <code>nano examples/Makefile</code></li>
<li>Now run the BigHybrid (note that now you are in BigHybrid folder)</li>
</ul>

<p>I have been walking through a lot of pages in internet but have not found any answer except one. However, the answer is not complete, so I will share my experience here. </p>
<p>This feature is very useful, especially to summarize the issues found during certain tests, where the tests are reported in a confluence page. I found that there are so many questions about this, but Atlassian seems does not want to bother with this request. I found one way to do this by the following tricks</p>
<p>Take one JIRA issue that related to the target confluence page (in this case, say it is GET-895)
Find the global ID of a JIRA issue: </p>
<div><pre class="line-numbers"><code class="language-none">http://bach.dc1.scram.com:8080/rest/api/latest/issue/GET-895/remotelink</code></pre></div>
<p>It will show the JSON like this:</p>
<div><pre class="line-numbers"><code class="language-none">[{"id":28293,"self":"http://bach.dc1.scram.com:8080/rest/api/latest/issue/GET-895/remotelink/28293","globalId":"appId=662e1ccf-94da-3121-96ae-053d90587b29&pageId=105485659","application":{"type":"com.atlassian.confluence","name":"Confluence"},"relationship":"mentioned in","object":{"url":"http://bach.dc1.scram.com:8090/pages/viewpage.action?pageId=105485659","title":"Page","icon":{},"status":{"icon":{}}}}]</code></pre></div>
<p>Then take the globalId from there to search issue in JIRA</p>
<div><pre class="line-numbers"><code class="language-none">issue in issuesWithRemoteLinksByGlobalId("appId=662e1ccf-94da-3121-96ae-053d90587b29&pageId=105485659")</code></pre></div>
<p>However, this morning I found out that the filter only works for a single user. So for example I report GET-001 and Denis report GET-002, the filter will show only JIRA tickets from me. In order to include Denis's report, we have to take one JIRA ticket from Denis, find the globalID and add the query into JQL. For example, the above query will be:</p>
<div><pre class="line-numbers"><code class="language-none">issue in issuesWithRemoteLinksByGlobalId("appId=662e1ccf-94da-3121-96ae-053d90587b29&pageId=105492363") or issue in issuesWithRemoteLinksByGlobalId("appId=662e1ccf-94da-3121-96ae-053d90587b29&pageId=105492386")</code></pre></div>

<p>I had difficulty in finding any large text file. In Google, some of them suggest to download from wikimedia dump and some of them from gutenberg project. However, the following steps are a lot easier than going to all the menus in either wikimedia or gutenberg.</p>
<h2 id="toc_0">Enter any small text file</h2>
<p>In the first step, just enter any small text file. For example:</p>
<div><pre><code class="language-none">$ echo 'arwan ahmad khoiruddin' > mytext.txt</code></pre></div>
<h2 id="toc_1">Merge the text into big file</h2>
<p>Next, you can merge the text into big file. Here's how</p>
<div><pre><code class="language-none">$ cat mytext.txt mytext.txt mytext.txt > merged.txt</code></pre></div>
<p>The content of file <code>merged.txt</code> will be </p>
<div><pre><code class="language-none">arwan ahmad khoiruddin arwan ahmad khoiruddin arwan ahmad khoiruddin</code></pre></div>
<p>So, if you want to create big file, you can just repeat the cat as many as possible. For example</p>
<div><pre><code class="language-none">$ cat mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt mytext.txt > merged.txt</code></pre></div>
<p>Enjoy</p>

<h2 id="toc_1">Free-form inputs</h2>
<h3 id="toc_2">To compute, press <code>SHIFT + ENTER</code></h3>
<p><code>In[1]:= 3 + 9</code> <code>SHIFT + ENTER</code></p>
<p><code>Out[1]:= 12</code></p>
<h3 id="toc_3">To suppress output, add <code>;</code> after the line</h3>
<p><code>In[1]:= 3 + 9;</code> <code>SHIFT + ENTER</code> -> no output</p>
<h3 id="toc_4">You can execute multiple lines at once</h3>
<p><code>In[1]:= a = 2</code></p>
<p><code>b = a + 2</code></p>
<p><code>c = b ^ 3</code> <code>SHIFT + ENTER</code></p>
<p><code>Out[1]:= 2</code></p>
<p><code>Out[2]:= 4</code></p>
<p><code>Out[3]:= 64</code></p>
<p>Starting from now, when we have output, it means that in the end of the previous line, we press <code>SHIFT + ENTER</code>.</p>
<h3 id="toc_5">To get the most recent output, use <code>%</code></h3>
<p><code>In[1]:= 3 + 9</code></p>
<p><code>Out[1]:= 12</code></p>
<p><code>In[1]:= % + 5</code> </p>
<p><code>Out[1]:= 17</code></p>
<h2 id="toc_6">Basics in Programming</h2>
<h3 id="toc_7">Variable</h3>
<p>A variable starts with letters. If you want, you may add numbers into the variable name. It is much better if you start the variable name with lowercase</p>
<p><code>In[1]:= myVariable123 = 2</code></p>
<p><code>Out[1]:= 2</code></p>
<p>Please notice how I join the two words and the number into a single word. If you put space between the variable name, it will indicate multiplication</p>
<p><code>In[1]:= x = 3;</code></p>
<p><code>5 x x</code></p>
<p><code>Out[1]:= 45</code></p>
<p>To clear the variable, use <code>Clear</code> function</p>
<p><code>In[1]:= x = 2</code></p>
<p><code>Out[1]:= 2</code></p>
<p><code>In[2]:= 2 x</code></p>
<p><code>Out[2]:= 4</code></p>
<p><code>In[3]:= Clear[x]</code></p>
<p><code>In[4]:= 5 x x</code></p>
<p><code>Out[4]:=</code> \(5x^2\)</p>
<h3 id="toc_8">Conditional Statement</h3>
<p>The <code>if</code> contains three parts i.e. test, then (what to do if true), and else (what to do if false). The syntax is as follows</p>
<p><code>If[test, then, else]</code></p>
<p>Examples</p>
<p><code>In[1]:= If[5<8, Print["5 is less than 8"], Print["5 is more than 8"]</code></p>
<p><code>5 is less than 8</code></p>
<h3 id="toc_9">List</h3>
<p>List of items are indicated by <code>{ ... }</code></p>
<p><code>In[1]:= {1, 2, 3} * 2</code> </p>
<p><code>Out[1]:= {2, 4, 6}</code></p>
<p>The index of the list starts from 1</p>
<p><code>In[1]:= {3, 8, 2, 9}[[3]]</code></p>
<p><code>Out[1]:=2</code></p>
<h3 id="toc_10">Loop</h3>
<p>The syntax used for the loop in Mathematica is as follows</p>
<p><code>For[start, test, incr, body]</code></p>
<p><code>start</code> indicate the condition when the loop is started (initialization)</p>
<p><code>test</code> indicate the condition to check during the loop</p>
<p><code>incr</code> indicate the increment happen on each loop</p>
<p><code>body</code> indicate the operation done during the loop</p>
<p>Example:</p>
<p><code>In[1]:= For[i=0, i<4, i++, Print[i]]</code></p>
<p><code>0</code></p>
<p><code>1</code></p>
<p><code>2</code></p>
<p><code>3</code></p>
<p>If you want to add more command on each section, separate the command using semicolon <code>;</code></p>
<p>Example</p>
<p><code>In[1]:= For[i = 0, i < 4, i++, Print[i]; Print["hello"]]</code></p>
<p><code>0</code></p>
<p><code>hello</code></p>
<p><code>1</code></p>
<p><code>hello</code></p>
<p><code>2</code></p>
<p><code>hello</code></p>
<p><code>3</code></p>
<p><code>hello</code></p>
<h2 id="toc_11">Data Visualisation</h2>
<h3 id="toc_12">Plot</h3>
<p>You can plot single function using the following command</p>
<p><code>Plot[f, {x ,</code> \(x_{min}\) <code>,</code> \(x_{max}\) <code>}]</code></p>
<p>Example</p>
<p><code>In[1]:=Plot[Sin[x], {x, 0, 6 Pi}]</code></p>
<p><img src="https://image.ibb.co/kmcp6L/Screen-Shot-2018-10-17-at-6-27-16-PM.png" alt=""></p>
<p>If you want to plot more than one functions, use list in the functions</p>
<p><code>Plot[{f1, f2, ... fn}, {x ,</code> \(x_{min}\) <code>,</code> \(x_{max}\) <code>}]</code></p>
<p>Example</p>
<p><code>Plot[{Sin[x], Cos[x]}, {x, 0, 6 Pi}]</code></p>
<p><a href="https://imgbb.com/"><img src="https://image.ibb.co/eWNBLf/Screen-Shot-2018-10-17-at-6-32-10-PM.png" alt="Screen-Shot-2018-10-17-at-6-32-10-PM" border="0"></a></p>
<h3 id="toc_13">ListPlot</h3>
<p>ListPlot function can be used to plot points. The syntax is as follows</p>
<p><code>ListPlot[{y1, y2, ... yn}]</code></p>
<p>Example</p>
<p><code>ListPlot[{1, 3, 5}]</code></p>
<p><a href="https://imgbb.com/"><img src="https://image.ibb.co/bXHHt0/Screen-Shot-2018-10-17-at-6-35-02-PM.png" alt="Screen-Shot-2018-10-17-at-6-35-02-PM" border="0"></a></p>
<h3 id="toc_14">ListLinePlot</h3>
<p>ListLinePlot can be used to plot a line through the points. The syntax is as follows</p>
<p><code>ListLinePlot[{y1, y2, ... yn}]</code></p>
<p>Example</p>
<p><code>ListLinePlot[{1, 3, 5, 8}]</code></p>
<p><a href="https://imgbb.com/"><img src="https://image.ibb.co/hcOqD0/Screen-Shot-2018-10-17-at-7-01-41-PM.png" alt="Screen-Shot-2018-10-17-at-7-01-41-PM" border="0"></a></p>
<h3 id="toc_15">Manipulate Commands</h3>
<p>Manipulate is used to see the changes in the output when the input is changed</p>
<p>Example</p>
<p><code>Manipulate[Plot[Sin[a x], {x, 0, 6}], {a, Pi, 3 Pi}]</code></p>
<p><a href="https://imgbb.com/"><img src="https://image.ibb.co/jxMSt0/Screen-Shot-2018-10-17-at-7-06-55-PM.png" alt="Screen-Shot-2018-10-17-at-7-06-55-PM" border="0"></a></p>

<p>In this post, I will give you an example for what I do to push a docker container into docker hub.</p>
<p>Here I will use my repository in docker hub i.e. <code>arwankhoiruddin/hadoopbuild</code>. You can find it here: <a href="">https://hub.docker.com/r/arwankhoiruddin/hadoopbuild/</a></p>
<p>In order to modify it, first I have to login</p>
<div><pre><code class="language-none">$ docker login
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.
Username (arwankhoiruddin): arwankhoiruddin
Password:
Login Succeeded</code></pre></div>
<p>Then I run the docker image</p>
<div><pre><code class="language-none">$ docker run -it arwankhoiruddin/hadoopbuild /bin/bash</code></pre></div>
<p>If it is not in my computer, it will download automatically from docker hub. After I finish, I type <code>exit</code> and I can save the changes into the docker hub. Followings are the steps</p>
<div><pre><code class="language-none">$ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
856e27749098 ubuntu:14.04 "/bin/bash" About an hour ago Exited (0) About an hour ago awesome_aryabhata</code></pre></div>
<p>Then commit the changes</p>
<div><pre><code class="language-none">$ docker commit 856e27749098 arwankhoiruddin/hadoopbuild</code></pre></div>
<p>Tag the image</p>
<div><pre><code class="language-none">$ docker tag arwankhoiruddin/hadoopbuild latest</code></pre></div>
<p>Push the image</p>
<div><pre><code class="language-none">$ docker push arwankhoiruddin/hadoopbuild
The push refers to repository [docker.io/arwankhoiruddin/hadoopbuild]

<p>In this post, I will give you a very basic example to run a hello world program in flask. What make it different with the other tutorial is that this will enable your program to run from a cloud server, not just on a local server. </p>
<h2 id="toc_0">Before we go further</h2>
<p>Because you want to run it in a cloud server, most probably you will use your ssh to connect and run it. However, you need to know that when you end your ssh session, your Flask server will also be shut down. To prevent that, my favourite is to use <code>screen</code>. If you are ubuntu lover like me, you can install it by typing</p>
<div><pre><code class="language-none">$ sudo apt-get install -y screen</code></pre></div>
<p>Before you do any work, start by typing </p>
<div><pre><code class="language-none">$ screen</code></pre></div>
<p>It will open a session for you. Later, after you run your Flask server, you may want to detach the session using this command</p>
<div><pre><code class="language-none">ctrl-a d</code></pre></div>
<p>If you later want to go back to your session, you can do it by using the following command</p>
<div><pre><code class="language-none">$ screen -r</code></pre></div>
<p>OK, without further ado, this is your first hello world program in Flask</p>
<div><pre><code class="language-python"># hello.py
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello():
return 'hello world'
if __name__ == '__main__':
app.run(host='0.0.0.0', port=5000)</code></pre></div>
<p>You can run the program using</p>
<div><pre><code class="language-none">$ python hello.py</code></pre></div>
<p>Say that you run it in cloud with address 183.93.3.23, you can open the hello world program from your browser by typing</p>
<div><pre><code class="language-none">183.93.3.23:5000</code></pre></div>
<p>This will show you a welcome message</p>
<div><pre><code class="language-none">hello world</code></pre></div>
<p>After I mentioned earlier, if you want to let your hello world server to run, you can just detach from the session using the following command in terminal</p>
<div><pre><code class="language-none">ctrl-a d</code></pre></div>
<p>Hope it helps :D</p>

<p>There are several ways to reload <code>~/.bashrc</code> and <code>~/.bash_profile</code> without logging off or restart. You can do one of the following command</p>
<ul>
<li><code>source ~/.bashrc</code></li>
<li><code>. ~/.bashrc</code></li>
<li><code>exec bash</code>. This is my favourite. Like bash inception. Hahaha.</li>

In KLIA2, the first night will be 42 MYR. After that, it will be reduced to 21 MYR. Even after reduced, the fee is still very very very very very expensive. I will prefer to spend the money to buy some foods. 21 MYR equals to two or three times meals. Hahaha<br />
<div>
<br /></div>
<div>
<b>OK. So where you should put your car when you travel from KLIA or KLIA?</b></div>
<div>
<br /></div>
<div>
I found some answers, but for myself, I prefer to park my car at Salak Tinggi Station. In Google Maps, you can find the coordinate from this link: https://goo.gl/maps/WWSdj2ZiTN22</div>
<div>
<br /></div>
<div>
Previously it was so cheap to park in Salak Tinggi. Only 3 MYR per night. However, now they increase the fee to 3 MYR for parking during the day and 8 MYR for overnight parking. However, 8 MYR is not that much compared to 21 MYR. Right?</div>
<div>
<br /></div>
<div>
<b>OK. So after parking the car, how can we go to KLIA or KLIA2?</b></div>
<div>
<b><br /></b></div>
<div>
The first KLIA Transit train from KL-Sentral to KLIA2 starts at 4.33 am and the last one is 00.03 am. The first train will reach Salak Tinggi at 5.00 am. The last train will reach Salak Tinggi at 00.32 am. The train will be available every 15 minutes (peak hour) and every 30 minutes (every off-peak hour).</div>
<div>
<br /></div>
<div>
It will need 7 minutes to go to KLIA and 11 minutes to KLIA2 from Salak Tinggi Station. </div>
<div>
<br /></div>
<div>
<b>What is the price for the train tickets from Salak Tinggi to KLIA or KLIA2?</b></div>
<div>
<br /></div>
<div>
The price for the KLIA Transit 4.90 MYR for adults and 2.20 MYR for kids. Same for KLIA and KLIA2.</div>
<div>
<br /></div>
<div>
So, next time you travel, better to park your car at Salak Tinggi. But plan ahead for the waiting for the train and the 7/11 minutes travel from Salak Tinggi to KLIA/KLIA2.</div>
<div>
<br /></div>
<div>
Hope this post is useful for you :D</div>

<h3 id="toc_2">
Use web interface</h3>
If you like to work in black screen like me, this will be the last option for you. However, some of the people love this way... :D<br />
To open the web interface, by default, it is in <code>http://<server-address>:8088</server-address></code><br />
So, for example your server is <code>192.168.10.192</code>, you can open the web interface using<br />
<div>
<pre><code class="language-none">http://192.168.10.192:8088</code></pre>

<p>By default, you have to run <code>docker</code> using <code>sudo</code>. When you try to run it without sudo, you will get</p>
<div><pre><code class="language-none">$ docker images
Got permission denied while trying to connect to the Docker daemon socket</code></pre></div>
<p>In order to run without sudo, you will need to do the following steps</p>
<ul>
<li>Add the docker group if it does not already exist</li>
</ul>
<div><pre><code class="language-none">sudo groupadd docker</code></pre></div>
<ul>
<li>Add the user to the docker group. If you want to add the current user, you can just use this</li>
</ul>
<div><pre><code class="language-none">sudo gpasswd -a $USER docker</code></pre></div>
<p>If you want to add, say user <code>user1</code>, then you should just do</p>
<div><pre><code class="language-none">sudo gpasswd -a user1 docker</code></pre></div>
<p>After you do the above steps, log out and now you can run <code>docker</code> without <code>sudo</code>.</p>

<body>
<p>In this tutorial, we will write python code to send to multiple emails. Followings are the scenario:</p>
<ul>
<li>Emails will be listed in a text file</li>
<li>The Python code will read the emails and send email to each address</li>
<li>The email used is gmail</li>
</ul>
<h2 id="toc_0">Allow Less Secure App</h2>
<p>You must allow low secure app in your google account setting before you can run the code. In order to do that, go to <code>https://myaccount.google.com/?pli=1</code>, navigate to <code>sign in and security</code>, scroll down and enable the <code>allow less secure apps</code></p>
<h2 id="toc_1">Write the Python Code</h2>
<p>Now we go to the most interesting part i.e. writing the code.</p>
<h3 id="toc_2">Simplest Code</h3>
<p>We will start with a very simple code to send to one account</p>
<div><pre class="line-numbers"><code class="language-python">#!/usr/bin/python
import smtplib
fromaddr = "mymail@gmail.com"
frompass = "mypass"
text = "this is the body"
email = "targetmail@gmail.com"
# login and send the email
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login(fromaddr, frompass)
server.sendmail(fromaddr, email, text)
server.quit()
print "sent to " + email
</code></pre></div>
<p>Say you save the file to be sendmail.py. Now you can run it in terminal</p>
<div><pre class="line-numbers"><code class="language-none">$ chmod +x sendmail.py
$ ./sendmail.py
sent to targetmail@gmail.com</code></pre></div>
<p>When you open your email, you will find a new email with <code>(no subject)</code> with the body as <code>this is the body</code></p>
<h2 id="toc_3">Complete Email Content</h2>
<p>As you notice, your program will send email without subject. To put complete email content, you should modify your program as follows</p>
<div><pre class="line-numbers"><code class="language-python">#!/usr/bin/python
import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
from email.MIMEBase import MIMEBase
from email import encoders
fromaddr = "mymail@gmail.com"
frompass = "mypass"
email = "targetmail@gmail.com"
msg = MIMEMultipart()
msg['from'] = fromaddr
msg['to'] = email
msg['Subject'] = "test mail"
body = "this is the body"
msg.attach(MIMEText(body, 'plain'))
text = msg.as_string()
# login and send the email
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login(fromaddr, frompass)
server.sendmail(fromaddr, email, text)
server.quit()
print "sent to" + email
</code></pre></div>
<p>You can run it again</p>
<div><pre class="line-numbers"><code class="language-none">$ ./sendmail.py
sent to targetmail@gmail.com</code></pre></div>
<p>In the target email, you will find that now you have the subject. If you want to add attachment with your email, you can add some lines as follows. But, before, create a file named <code>emails</code>. We will use the file as the attachment. If you use *nix, you can create the file using the following command</p>
<div><pre class="line-numbers"><code class="language-none">$ touch emails</code></pre></div>
<p>Now add some lines in your Python code as follows</p>
<div><pre class="line-numbers"><code class="language-python">#!/usr/bin/python
import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
from email.MIMEBase import MIMEBase
from email import Encoders
import os
fromaddr = "mymail@gmail.com"
frompass = "mypass"
email = "targetmail@gmail.com"
msg = MIMEMultipart()
msg['from'] = fromaddr
msg['to'] = email
msg['Subject'] = "test mail"
body = "this is the body"
msg.attach(MIMEText(body, 'plain'))
# prepare the attachment
part = MIMEBase('application', "octet-stream")
part.set_payload(open(os.getcwd() + "/emails", "rb").read())
Encoders.encode_base64(part)
part.add_header('Content-Disposition', 'attachment; filename="emails.txt"')
# attach into email
msg.attach(part)
# convert msg into string
text = msg.as_string()
# login and send the email
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login(fromaddr, frompass)
server.sendmail(fromaddr, email, text)
server.quit()
print "sent to " + email
</code></pre></div>
<p>Now run it again</p>
<div><pre class="line-numbers"><code class="language-none">$ ./sendmail.py
sent to targetmail@gmail.com</code></pre></div>
<p>You will find that the email now has the attachment. The name of the attachment is email.txt. As we put nothing in the <code>emails</code> file, the file content sent through the email will be just an empty file.</p>
<h2 id="toc_4">Read Target Email from File</h2>
<p>Now we will make it more interesting by reading the target email from the text file. Create a text file using your favourite editor. In my case, I prefer to use <code>nano</code>. In my case, I did the followings</p>
<div><pre class="line-numbers"><code class="language-none">$ nano emails</code></pre></div>
<p>My list of emails is something like this</p>
<div><pre class="line-numbers"><code class="language-none">firstmail@something.com
secondmail@something.com
thirdmail@something.com</code></pre></div>
<p>Your Python code will be like this</p>
<div><pre class="line-numbers"><code class="language-python">#!/usr/bin/python
import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
from email.MIMEBase import MIMEBase
from email import Encoders
import os
fromaddr = "mymail@gmail.com"
frompass = "mypass"
email = "targetmail@gmail.com"
msg = MIMEMultipart()
msg['from'] = fromaddr
msg['Subject'] = "test mail"
body = "this is the body"
msg.attach(MIMEText(body, 'plain'))
# prepare the attachment
part = MIMEBase('application', "octet-stream")
part.set_payload(open(os.getcwd() + "/emails", "rb").read())
Encoders.encode_base64(part)
part.add_header('Content-Disposition', 'attachment; filename="emails"')
# attach into email
msg.attach(part)
f = open(os.getcwd() + "/emails")
for email in f:
msg['To'] = email
text = msg.as_string()
# login and send the email
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login(fromaddr, frompass)
server.sendmail(fromaddr, email, text)
server.quit()
print('sent to ' + email)
print "Sending email finished"
</code></pre></div>
<p>When you run the Python code, it will be</p>
<div><pre class="line-numbers"><code class="language-none">$ ./coba.py
sent to firstmail@something.com
sent to secondmail@something.com
sent to thirdmail@something.com
Sending email finished</code></pre></div>

Dependent pass can be applied for your spouse, children, parents, or adopted children.<br />
<h3>
Document Checklist</h3>
I got a checklist from immigration office. So, rather than you have to go there only to get the checklist, it will be much better if I write the checklist for you. You can also download each form needed. Followings are the checklist for long term application of social visit pass for dependent/student's companion:<br />
<ol>
<li><a href="http://picocurl.com/8jS" target="_blank">IMM 12</a> for new application or <a href="http://picocurl.com/8jz" target="_blank">IMM 55</a> for extension</li>
<li><a href="http://picocurl.com/8TN" target="_blank">IMM 38</a></li>
<li>Proof of relationship, verified by Embassy/Representative/High Commission Office (original and copy)</li>
<ul>
<li>Marriage certificate (husband and wife)</li>
<li>Birth certificate (children)</li>
<li>Custody of children letter/adopted child certificate (for step children and adopted children only)</li>
<li>Birth certificate of student pass holder (when applying biological father or mother). Citizen of Republic of China have to get proof of relationship from Malaysian representative office in China</li>
</ul>
<li>Letterhead from institution including information regarding the position in institution (if sent by institution representative)</li>
<li>Confirmation letter from institution</li>
<li>Copy of passport page that contain information and valid pass</li>
<li>Passport copy of student pass holder (page that contain information & latest pass)</li>
<li>Health insurance policy of applicant within the valid year</li>
<li>Prove of the ability to self-sustain in Malaysia</li>
<li>Personal bond (duty stamp RM 10) for each applicant</li>
<li>Bank statement</li>
</ol>
<div>
<b>Some notes regarding the checklist:</b></div>
<div>
<ul>
<li>For renewal process, ignore document 3 and 10</li>
<li>Amendment of personal bond is not allowed</li>
<li>Passport copy verified by the institution is needed if the applications resides outside the country</li>
<li>Applicant/institution should be willing to provide additional documents if being prompted by the immigration officers</li>
<li>Original documents should be provided during submission of application</li>
<li>Only completed application will be processed</li>
</ul>
<div>
<h3>
Some more details based on my experience</h3>
</div>
</div>
<div>
<ul>
<li>You will need to have photographs of your dependents. The photograph is visa size with white background. Print at least 3 or 5 for spare.</li>
<li>Ensure that your documents are correct, including the photograph. If you have more than one children, sometime you may misplace their photograph.</li>
<li>If your kid was born outside Malaysia, you will need to verify the birth certificate in the respective embassy. If your kid(s) was/were born in Indonesia, you have to verify the birth certificate in KBRI and it took two days to finish. If you want to be faster, you can go to Konjen in Johor or Penang, and it will take only one day to finish. However, if your kid was born in Malaysia, you just need to make a copy of his/her birth certificate. You can refer on how to get birth certificate for kid born in Malaysia in <a href="http://arwankhoiruddin.blogspot.my/2011/11/akte-paspor-dan-visa-untuk-anak.html" target="_blank">this post</a> (sorry it is in Bahasa, you may use Google Translate if you need to).</li>
<li>You will also need to fill <a href="http://picocurl.com/8x2" target="_blank">security bond form</a>. You then need to put 10 ringgit duty stamp on the form</li>
<li>You can get the duty stamp in POS LAJU (maybe you can get it elsewhere, but I went to poslaju to get it)</li>
<li>You need to go to Lembaga Hasil for the security bond form to be stamped</li>
<li>To prove the ability to self-sustain in Malaysia, you can use your offer letter showing the scholarship during your study</li>
<li>The bank statement needs to be verified by the respected bank. For example, if you have CIMB account, you have to go to CIMB to verify the bank statement. However, if you are Indonesian like me, you can use your bank book</li>
<li>If your supervisor is Malaysian, like me, ask him to be your guarantor. Otherwise, if you supervisor is not Malaysia, you may ask your Malaysian friend to be the guarantor</li>
<li>In the security bond form, it is said that you have to provide some amount of money as security bond. However, you don't need to provide the money as long as you don't make any trouble in Malaysia. That amount of money is just to say that it will be available if anything goes wrong.</li>
</ul>

<p>In this tutorial, I show steps to modify and edit sikulix under OSX environment. This should not be different with other *nix environment. However, for windows environment, you may need to adjust yourself.</p>
<h2 id="toc_1">Modify your code</h2>
<ul>
<li>Clone from the <a href="https://github.com/RaiMan/SikuliX-2014">repository</a></li>
<li>Open the repository as maven project in netbeans. You can easily use this button to open the project <img src="http://i.imgsafe.org/b755629bfb.png" alt="open"></li>
<li>You will see that the cloned project appeared in open windows like the following <img src="http://i.imgsafe.org/b7557475cd.png" alt=""></li>
<li>Open the project. It will be like this <img src="http://i.imgsafe.org/b755855f3c.png" alt=""></li>
<li>Modify any part you want to modify</li>
<li>Clean and build the maven project. If you open other sub project of sikulix, make sure that you clean and build only the main sikulix maven project <img src="http://i.imgsafe.org/b75596f132.png" alt=""></li>
</ul>
<h2 id="toc_2">Create Installer</h2>
<p>Go to File Finder in the repository folder. You will see one file named runSetup. Using your terminal and <code>cd</code> to the folder and run the setup.</p>
<p><code>$ runSetup</code></p>
<p>It will bring you to SikuliX installation. Please remember that if you build yourself, ALWAYS do it in offline mode, means that you are not supposed to download anything during the installation. In other words, because SikuliX will need some packages/libraries, before installing SikuliX using your own build, you MUST install SikuliX in your computer by running normal build first. You can download the normal build <a href="https://launchpad.net/sikuli/sikulix/1.1.0">here</a></p>
<p>Back to <code>runSetup</code>. You will see SikuliX installation window as follows</p>

<p>Before you continue, please pay attention to <code>in this folder</code> part. That part shows you where you can find your new build. To make myself clearer, I mean this part</p>
<p><img src="http://i.imgsafe.org/b7f14c690f.png" alt=""></p>
<p>It shows me that I can find the build in <code>/Users/arwankhoiruddin/Library/Application Support/Sikulix/SikulixSetup</code> folder</p>
<p>Then follow the instructions carefully. I repeat once more, please do not download anything during this installation.</p>
<p>Now go to <code>SikulixSetup</code> folder. You will find your new and fresh build there</p>
<p><img src="http://i.imgsafe.org/b81d3cbbca.png" alt=""></p>
<p>Just move or copy SikuliX to <code>/Applications</code> folder and voila! Your newly build sikulix is ready to use</p>

Recently, I use the IDE to work on python. However, I got problem because I need to run the python from some virtual environments. To make it happen, this is what I did:<br />
<br />
1. Create a shell script to run the virtual environment. For example we name the shell script runpyenv.sh, we may run the script with runpyenv.sh mycode.py. The code $1 will take the first input argument after the shell script name.<br />
<blockquote class="tr_bq">
source ~/arwanenv/bin/activate<br />
python $1</blockquote>
2. Now make the shell script to be executable<br />
<blockquote class="tr_bq">
sudo chmod +x runpyenv.sh</blockquote>
3. Now you put the shell script inside the command of your Komodo. It will be better if you make the file parameter to be automatic. Here is the command in your Komodo<br />
<blockquote class="tr_bq">
~/runpyenv.sh %F</blockquote>
Enjoy. Share your ideas in the comment if you have better idea.<br />

Today I found something interesting I can do with ubuntu terminal i.e. stream online radio via terminal. Here are the steps needed to stream your chosen radio via terminal<div>
<br /></div>
<div>
<div>
<b>Install mplayer</b></div>
Update your ubuntu repository to ensure that you use the latest update then install mplayer using apt-get<br />
<blockquote class="tr_bq">
$ sudo apt-get update</blockquote>
<blockquote class="tr_bq">
$ sudo apt-get install mplayer</blockquote>
</div>
<div>
<b>Find the IP address of the radio you want to listen. </b></div>
<div>
You might find it from anywhere, but I prefer to choose from https://www.xatworld.com/radio-search/. In the following screen capture, I show you when I was trying to find IP address for MQ FM (it is a moslem radio in Indonesia). You just need to supply the radio name, press "search", after it is found then you can just press "Find IP" button. Voila! Your radio IP address is there.</div>

<br />
There are some tutorials that suggest the installation using PPA. However, sometime it does not work because the PPA listed is no longer available or for any other reasons. In this post, I write manual way for installation. This way is much safer and more guarantee that it will work. Please let me know if you have any problem.<br />
<br />
<b>Preparation</b><br />
If you run 64-bit ubuntu, install the following packages first. If you run 32-bit, you may skip this step and go to the next step<br />

The problem that I face for team development was that it is quite difficult to communicate the testing results to the team, because the results are in terminal so only us and God know :D<br />
<br />
Fortunately, somebody out there know my problem and create this amazing HTMLTestRunner.py. This tool is very handy and very easy to use. It almost feels like you don't need to do anything. OK, here's one example on how we use HTMLTestRunner. Ah, forget it. Download HTMLTestRunner.py from <a href="http://tungwaiyip.info/software/HTMLTestRunner.html" target="_blank">this website</a>, and put somewhere in your computer. Say in this example, I put in ~/Downloads/HTMLTestRunner folder<br />
<br />
<span style="font-family: Courier New, Courier, monospace;">import unittest</span><br />

<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;"> return suite</span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">if __name__ == "__main__":</span><br />
<span style="font-family: Courier New, Courier, monospace;"> suite = suite()</span><br />

<br />
1. Import sys<br />
2. Append the path to the script into sys.path<br />
3. Import your python script<br />
<br />
Here is an example<br />
<br />
<span style="font-family: Courier New, Courier, monospace;">import sys</span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">sys.path.append("/Users/arwankhoiruddin/Downloads/python_packages/HTMLTestRunner")</span><br />
<span style="font-family: Courier New, Courier, monospace;"><br /></span>
<span style="font-family: Courier New, Courier, monospace;">import HTMLTestRunner</span><br />
<br />
However, it has some limitations.

To check it, we can use built-in SikuliX script. Following is an example of OS checking<br />
<br />
if Settings.isWindows():<br />
print "I am running on Windows"<br />
elif Settings.isLinux():<br />
print "I am running on Linux"<br />
elif Settings.isMac():<br />
print "I am running on Mac"<br />
<br />
That's it. Hope it helps.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2984745473843998572.post-55593703592606849622016-04-07T21:20:00.000-07:002016-04-07T21:20:07.669-07:00Make vi appearance to be "real programming IDE""why not just use IDE or something like gedit?"<br />
<br />
I had that question long ago and that made me stick to GEdit and other IDEs. However, when I have to do some works on files in server, I just realise that I have to familiarise myself to command-based editor. And, that's the beginning for me to know vi.<br />
<br />
When I open it, the appearance is so boring. No line number, no syntax color. So, I decided to make at least that two things to make vi to be IDE like. Hahaha... Here's what I did:<br />
<br />
$ vi ~/.vimrc<br />
<br />
then type these lines in vimrc file<br />
<br />
<div class="p1">
<span class="s1">set</span><span class="s2"> </span><span class="s3">number</span> </div>
<div class="p1">
<br /></div>
<div class="p2">
<span class="s3">syntax</span><span class="s2"> </span><span class="s4">on</span></div>
<br />
<div class="p2">
<span class="s3">colorscheme</span><span class="s2"> desert</span></div>
<div class="p2">
<span class="s2"><br /></span></div>
<div class="p2">
====</div>
<div class="p2">
set number will add line number on the left part of vi</div>
<div class="p2">
<br /></div>
<div class="p2">
syntax on will add colour of the syntax</div>
<div class="p2">
<br /></div>
<div class="p2">
colorscheme desert will set the colour scheme to be "desert"</div>
<div class="p2">
<br /></div>
<div class="p2">
That's it. I hope I can add some more customization of vi in the future. I feel that I am falling in love for the second time. Oh, vi... I love you.</div>
