Update: Please read the comments or just use killall <appname>
If you know the command
ps -A
then tou will probable also know
ps -A | grep firefox
now you can manually kill this via
kill -9 <ID>
Where <ID> is from the last output. But how to do this in one line? If your ps command knows:
ps opid= -C firefox
(should print the <ID>)
Then you can simply do
kill -9 $(ps opid= -C firefox)
If you read through the comments of Amy Fowler’s Blogentry (nice post by the way)
steveonjava posted the following news:
“We are releasing a SceneToJComponent class that makes it easy to embed JavaFX Scenes in Swing applications as a part of the JFXtras 0.5 release. The final release will come out in a few days, but for now you can try out the beta here”
Hopefully this is a reliable method which will work for the next javafx version too 🙂
Thanks for making this possible!
Did you ever have hassle with manual installation of packages (.sty files) in latex under linux? If yes the following procedure will help you a lot to make the windows-latex-packagemanager called miktex working under linux. With this manager it is one command or one click to install a package without any websearches!!
initexmf --help
sudo initexmf --admin --user-install=/var/lib/texmf/
sudo mpm --install=fltpage
sudo mpm --update
sudo mpm --list | grep a0
=> a0poster
Thats all! And it is nice! A lot better than manual installation.
It took me some time to collect the hibernate.cfg.xml data which is necessary for derby, oracle and h2. So here are the default settings for those databases:
<property name=”hibernate.connection.driver_class”>org.apache.derby.jdbc.ClientDriver</property>
<property name=”hibernate.connection.url”>jdbc:derby://localhost:1527/databaseName;create=true</property>
<property name=”hibernate.connection.username”>admin</property>
<property name=”hibernate.connection.password”>admin</property>
<!– no schema necessary –>
<property name=”hibernate.dialect”>org.hibernate.dialect.DerbyDialect</property>
To make it complete here are the maven settings for the databases:
I highly recommend to read this article:

Have Fun!
After this you surely will be a sceptical about open source projects being the number one 😉
The web site of shine is still available, but nearly all other things were removed from sourceforge.
Thanks for your attention and comments the last months! Hope you will enjoy the next months …
I started my blog in November 2007. Now, May 2009 was the first month with more than 5 000 users (and even over 6000 -> 6080).
The monthly statistics looks a bit like the physical phenomena called ‘Maker-fringes’:

In my diploma thesis 2 years ago I studied this phenomena in detail.
BTW: this fancy 😉 picture I got with my performant Java genvlin plotter.
There are several tools to measure the code quality of my free timetabling software TimeFinder. Here are the tools I tried with success:
mvn findbugs:findbugs
which will use version 1.3.8 out of the box
mvn pmd:pmd
after you specified the following in the pom.xml under<reporting> <plugins> :
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-pmd-plugin</artifactId>
<version>2.3</version>
<configuration>
<targetJdk>1.5</targetJdk>
</configuration>
</plugin>
Other tools could be
but I didn’t tried them so far.
For Findbugs and pmd there is a NetBeans plugin (SQE … software quality environment) which looks promising, but fails with a NullPointerException after I installed it via the update center and tried it on my project. Maybe I should use one of the snapshots. (BTW: I successfully used the pmd-plugin and findbugs in the standalone version).
Sonar is another interesting approach to use several code quality tools at a time. With Sonar it is possible to see the violations or possible bugs over das or weeks – so, you are looking at the improvements and you will not get lost in the mass of bugs at the beginning. Another “multi-tooling” project is XRadar.
A little bit offtopic, but a great tool is proguard, which shrinks, optimizes, obfuscates and preverifies Java class files. There is even a maven plugin for that.
Today I created a video documentation of how to create an individual schedule for JavaOne 2009 with TimeFinder.
Start the flash video it here. (3.5 MB)
Have a look at this presentation where this post is presented as pitfall #3 !
Lesson learned. See comments 🙂
There are a lot microbenchmark tips out in the www. The intent of them differs from author to author.
Today I want to show how you could compare e.g. different algorithms. You could simply do:
int COUNT = 1000000;
long firstMillis = System.currentTimeMillis();
for(int i = 0; i < COUNT; i++) {
 runAlgorithm();
}
System.out.println("Mean runtime of algorithm in seconds:"+(System.currentTimeMillis()-firstMillis) / 1000.0 / COUNT);
There are several problems with this approach, which results in very unpredictable results:
long firstNanos = mx.getCurrentThreadCpuTime(); ThreadMXBean mx = ManagementFactory.getThreadMXBean();
instead of
long firstMillis = System.currentTimeMillis();
After this I got relative stable results: The difference of maximal and minimal value for the result is less then 4% after 10 runs.
