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

My Sun Certified Enterprise Architect for J2EE Platform report

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!!! ;-)

How Nokia Users Drive Innovation
An interesting article by BusinessWeek, note the really strange form factors (click View Slide Show on the left).
Bossa Conference's photostream
I attended the BOSSA Conference in Brazil back in March, a cool mobile Linux event. Here is the Flickr photostream.
LG and Samsung increasing market share, Nokia leading...
Market leader Nokia continued at a slow and steady growth pace, increasing its market share from 40.6 per cent to 40.9 per cent. While Mawston said that 2008 is shaping up to be the year of the Koreans, with improved handset portfolios enabling LG to grow at almost four times the annual industry average, while Samsung is growing over two times faster.

Android gets its mobile web server
While there are no Android devices hitting the market yet, this interesting article talks about porting the well-known Jetty Java Web Container and HTTP Server to Android.
While I am not a fan of Android mainly due to the fact that its Java is not standard and not based on standard Java ME, it is cool to see a real Java Web Container running in a mobile device.
You know, the S60 platform has a similar solution called MWS (Mobile Web Server) developed by the Nokia Research Center but it is LAMP oriented as far as I know.
Overall the cool thing is to see that it is really possible to host a server inside a mobile device :)
