Howto set Default Account in Thunderbird

Mozilla Thunderbird is a widely used Email client that is fast, friendly and can be extended with many plug-ins available for Linux, OS X and MS Windows platform. Licensed with Mozilla Public License 2.0 it is an open source software (OSS) with an active list of developers. The current version being 31 and more information can be found at Mozilla website.

Many email accounts can be created within this email client and this makes it easy to see all emails from one screen. Emails can be composed by opening the Thunderbird email client or via links that user clicks to activate the email composer. In order improve efficiency, one of the accounts can be assigned as the default email account and this is normally indicated in bold. This allows all new emails to use this account and users do not need to choose the account. I have listed the steps tested for Thunderbird version 24 and 31 where the example shows account2 in bold as the default account and we want to switch the default to account1.

Step 1: Open Thunderbird account's setting.

Start Thunderbird and from its menu bar at the top (default), choose Tools ->Account Settings...
Identify the default account that is used to send out emails. This is in bold, for example "account2"

Step 2: Set the default account

Choose the account to be used as the default. In this case, its "account1". At bottom of the window, click Account Actions. Choose "Set as Default".

Click OK, notice that this email account will go to the top of the list and is in bold font. Ensure all email screens are closed and restart Thunderbird.

Serious exploits in August and Sept 2014

These recent months have shown how the open source software model could handle (or is still handling) bugs that could be turned into an exploit of Linux servers. These are;

Shellshock (Sept 2014) - remotely take over a server.
BBC http://www.bbc.com/news/technology-29361794

Heartbleed (April 2014) - OpenSSL data could be intercepted.
BBC http://www.bbc.com/news/technology-28867113

The sheer number of Linux servers affected means that it is a serious threat and is wide spread. In Heartbleed, its patched but Shellshock is yet to have a patch to fully resolve the bug.

Interesting technical discussion on Shellshock is found at stackexchange.
https://unix.stackexchange.com/questions/157329/what-does-env-x-command-bash-do-and-why-is-it-insecure

How do you know if your shell is vulnerable? Hackernews recommends to run the following command in all the shell being used;

env X="() { :;} ; echo shellshock" /bin/sh -c "echo completed"
env X="() { :;} ; echo shellshock" `which bash` -c "echo completed"

If you see the text output "shellshock", please find a patch.

Chris, a contributor at Buzzfeed News, provided a good material on how 2 persons maintained the OpenSSL package, Steve Marquess and Stephen Henson. The commercial entity for this is known as OpenSSL Software Foundation.

Now doesn't it make you wonder who is responsible of bash shell and is it the same package for every Linux distro?

Creating an Android App with PhoneGap and Eclipse

This is the basics on creating a HelloWorld using PhoneGap, Cordova and Eclipse (provided by ADT).

I have downloaded and extracted:

1. Android Development Toolkit (ADT): adt-bundle-windows-x86_64-20130729.zip
2. Phonegap kit: phonegap-2.9.0.zip

Note: ADT provides the Eclipse IDE.

In order to start development, an Android project is created in Eclipse.

Step 1: Create an Android Project
Open Eclipse (Its in the ADT/eclipse folder) and choose File ->New ->Android Application Project

Application Name: Hello World (This is the name that will appear in the Play Store)
Project Name: HelloWorld (This is the name used by Eclipse to separate each project)
Package Name: com.example.HelloWorld

Select the default option for the remainder screens.

Step 2: Insert the Android/PhoneGap Libraries
In the project, left click on assets and create a new folder: www

Open the extracted PhoneGap/lib/android folder and do the following;

1. Copy PhoneGap/lib/android/cordova.js to Project's assets/www folder
2. Copy PhoneGap/lib/android/cordova-2.9.0.jar to Project's libs folder
3. Copy PhoneGap/lib/android/xml folder to Project's res folder

In the Project's lib/cordova-2.9.0.jar right click and choose Build Path ->Add to Build Path

Step 3: Create the starting page

In assets/www folder, create the text file index.html with following contents

 <!DOCTYPE HTML>  
 <html>  
 <head>  
 <title>PhoneGap</title>  
  <script type="text/javascript" charset="utf-8" src="cordova.js">  
  </script>  
  </head>  
  <body>  
  <h1>Hello PhoneGap</h1>  
  </body>  
  </html>  

Step 4: Configure to load the index.html

Edit the Project's src/com.example.HelloWorld/MainActivity.java

Before the first import statement, add

import org.apache.cordova.*;

Change extends Activity 

to extends DroidGap

or to extends PhoneGap

Change setContentView(R.layout.activity_main);

to

super.loadUrl("file:///android_asset/www/index.html");

Step 5: Configure Android specific configurations
Edit the AndroidManifest.xml (if unsure where, just place it before the Activity Application tag)

 <uses-permission android:name="android.permission.READ_PHONE_STATE" />  
 <uses-permission android:name="android.permission.INTERNET" />  
 <uses-permission android:name="android.permission.READ_CONTACTS" />  
 <uses-permission android:name="android.permission.WRITE_CONTACTS" />  

Edit the Activity tag by adding configChanges

 <activity  
  android:name="com.tboxmy.simpledisplay.MainActivity"  
  android:label="@string/app_name"   
  android:configChanges="orientation|keyboardHidden|screenSize" >  

Step 6: Test the application
Right click the project name and choose Run As ->Android Application

Unless you have a fast machine with huge RAM, some waiting time is required for the Application to start, after the Android Emulator starts.

UK declares Government Action Plan for OSS

UK Cabinet office website have declared the intent to adopt OSS. This is more towards leveling the playing field for OSS.

In its "Background" it mentions that 50% of its webserver use Apache. Looking up the cabinet office site, it uses Minstrel-httpd as its web server. The website uses MS ASP.NET. Well, the cabinet will need to lead the way by example by adopting more visible OSS solutions.

OSCC MAMPU have already under taken a rather unique approach for the Malaysian government since the year 2004. Among the OSS initiatives include making the government agencies aware, programmes to increase the human capital development and changing the management mind set. There were agency management who continue to seem unaware of the Malaysian Public Sector OSS Master Plan. However, the winds are changing and local government body have started their own campaigns on OSS.

But is UK they ready to accept OSS is not just the software, but whole change in the way the human capital will use systems? Are they ready to have users participating and contributing to the OSS community? The OSS business model will be different and will involve the international community along side the small businesses (including individuals). Unless the UK government adapt speedily, all the grand plans will be a long long struggle for many years to come.

I look forward to more OSS successes from UK.
