Android Malware increases

An interesting news reports that several malware applications have infected something nearly 5 million Android phones. I think this is something that will becoming more and more usual as Android grows to become the dominant platform.

It seems it is time to Google think more about the "platform security" and find ways to improve it...

The new C Programming language (C11, or C1x) published

It defines and clarifies:

-the representation of C programs;
-the syntax and constraints of the C language;
-the semantic rules for interpreting C programs;
-the representation of input data to be processed by C programs;
-the representation of output data produced by C programs;
-the restrictions and limits imposed by a conforming implementation of C.

It does not have:

-the mechanism by which C programs are transformed for use by a data-processing system;
-the mechanism by which C programs are invoked for use by a data-processing system;
-the mechanism by which input data are transformed for use by a C program;
-the mechanism by which output data are transformed after being produced by a C program;
-the size or complexity of a program and its data that will exceed the capacity of any specific data-processing system or the capacity of a particular processor;
-all minimal requirements of a data-processing system that is capable of supporting a conforming implementation.

ISO/IEC 9899:2011 is designed to promote the portability of C programs among a variety of data-processing systems.

Change JVM parameters for NetBeans

To change the JVM parameters for NetBeans so that it runs better (in case you have hardware), go to Netbeans installation directory and find the netbeans.conf file inside the /etc dir:

C:\NetBeans-7.0.1\etc\netbeans.conf

Open the file netbeans.conf and find netbeans_default line:

netbeans_default_options="-J-server -J-Xss4m -J-Xms256m -J-XX:PermSize=64m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Duser.language=en -J-Duser.region=US"

I changed mine to include some additional JVM parameters. Also, note that I changed the mode from -client to -server (it runs better in my notebook's hardware I guess :-).

So the new JVM parameters are:

-J-server -J-Xms128m -J-Xmx512m -J-XX:+UseConcMarkSweepGC -J-XX:+UseParNewGC -J-XX:ParallelGCThreads=4 -J-XX:+CMSParallelRemarkEnabled -J-XX:NewSize=64m -J-XX:MaxNewSize=64m -J-XX:+DisableExplicitGC -J-XX:PermSize=64m -J-XX:MaxPermSize=256m

The complete line:

netbeans_default_options="-J-server -J-Xms128m -J-Xmx512m -J-XX:+UseConcMarkSweepGC -J-XX:+UseParNewGC -J-XX:ParallelGCThreads=4 -J-XX:+CMSParallelRemarkEnabled -J-XX:NewSize=64m -J-XX:MaxNewSize=64m -J-XX:+DisableExplicitGC -J-XX:PermSize=64m -J-XX:MaxPermSize=256m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Duser.language=en -J-Duser.region=US"

Enjoy the better performance! :-D

How to change NetBeans language (locale)

I am not used to any IDE in Portuguese (my native language) so I do not like to use the NetBeans interface in Portuguese.

So, in order to change that:

Go to Netbeans installation directory and find the netbeans.conf file inside the /etc dir:

C:\NetBeans-7.0.1\etc\netbeans.conf

Open the file netbeans.conf and find netbeans_default line and just add "-J-Duser.language=en -J-Duser.region=US" at the end of this line and restart NetBeans.

netbeans_default_options="-J-client -J-Xss4m -J-Xms256m -J-XX:PermSize=64m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Duser.language=en -J-Duser.region=US"

That is it! :-D

Strangely Security and Legacy Security were the worst scores.

I find it funny because that is where I have the best knowledge and experience in Java EE. The point here is that such topics have just a few (2 or 3) questions in the exam and if you provide one wrong question it is half the total :-)

I know I am a certified Architect at least!!! ;-)
