Old code

I spent the whole day with an old favorite: old code on the classpath because Eclipse is a fucked-up bitch! Remind next time to set the build directories for any new source directories if there might be conflicts with my ant setup and Eclipse’s stupid defaults.

Loopback Meditation State

Over the last four days at work I have learned a lot about OS, networks and java and that just because the source of the problem is something you would not expect, the problem may still be there.

The source of my problem was that for whatever insane reason the loopback device on the production server was dead.

The symptoms were not that funky and looking back should have pointed me to the problem quickly if only I had known such a problem existed.
# my program hangs on startup
# kill -3 gave me a stack trace and the source code told me that tomcat was simply trying to create a java.net.ServerSocket at that point, there’s not much that can go wrong there, hmmm? This one line method should have given me the first hint that it was not a “java issue”

at java.net.PlainSocketImpl.initProto(Native Method)
at java.net.ServerSocket.(ServerSocket.java:141)
at org.apache.tomcat.util.net.DefaultServerSocketFactory.createSocket
at org.apache.tomcat.util.net.PoolTcpEndpoint.initEndpoint(PoolTcpEndpoint.java:259)
at org.apache.coyote.http11.Http11Protocol.init(Http11Protocol.java:137)
at org.apache.coyote.tomcat5.CoyoteConnector.initialize(CoyoteConnector.java:1429)
at org.apache.catalina.core.StandardService.initialize(StandardService.java:609)

# somebody else found out that at one point or another tomcat got a timeout there
# after the timeout tomcat proceeded to run without further troubles
# stopping tomcat took just as long
# tcpdump told me that there was not really any traffic with that port on eth0 which finally led me to realize that this might not be the correct interface …..
# then everything resolved quickly: ifup lo generated the “device already configured” while ifconfig didn’t show the device, the sysadmin who had told me “the OS is healthy must be a java issue” agreed that it wasn’t good to have no loopback device

Now my tomcat starts as fast as before last wednesday and I wish I could catch the program that was responsible for putting the lo device into nirvana. By the way this only happened when I was trying to run tomcat as a standalone server with the org.apache.coyote.tomcat5.CoyoteConnector instead of plugging into apache.

Bretonischer Butterkuchen

Ingredients to this simple cake: 250g (salted) butter, 250g sugar, 250g flour and 4 eggs. Mix up everything, add salt if you didn’t have salted butter available and bake for one hour at 175┬░C.

How many chickens do you see?

This week-end I made the fascinating discovery that there are eggs with two yolks. Twin chickens? The first egg was pretty fascinating when four out of five eggs had two yolks it was a bit freaky. I think they are feeding the chicken too many fertility hormones or there is one really evil chicken trying to kill me. Just because I am paranoid that doesn’t mean that they are not out there to get me.

How to make news out of nothing

Last night, I was sitting in front of my computer. Quite happy because I got that fat new 19″ tft this week and because there was news from the European World of Warcraft Betatest

Zwei Wochen sind seit dem Ende der Anmeldephase f├╝r den europ├Ąischen World of Warcraft Betatest vergangen, und der Auswahlprozess f├╝r die erste Gruppe von Betatestern neigt sich dem Ende zu. Da wir allerdings eine beeindruckende Menge an Anmeldungen erhalten haben wird es noch eine Weile dauern, bis wir alle ausgewertet haben.

Die erste Welle von Authentifizierungsschl├╝sseln f├╝r den nicht-├Âffentlichen europ├Ąischen World of Warcraft Betatest wird den Betatesten per E-Mail zugeschickt werden, sobald der Auswahlprozess abgeschlossen ist. Mit diesen Schl├╝sseln werden die Tester ihre Accounts f├╝r den Betatest erstellen k├Ânnen. F├╝r die Erstellung der Accounts wird ein Webinterface verf├╝gbar sein, auf das von der offiziellen europ├Ąischen World of Warcraft Website aus zugegriffen werden kann (www.wow-europe.com/de, /fr, und /en).

This basically says that the beta will start as soon as they have sorted through all the applications. Which is good news because it says that something is indeed happening. I read this in the morning at work and thought: “Yay, I might get an account soon!”

Next thing I know, Rolland walks in: “Did you hear, they postponed the World of Warcraft beta!” Of course having read the other news, this came as a surprise. Well not quite, I knew where Rolland got his news. Gamestar – a German gaming magazine – had taken the news from Blizzard and made their own headline

World of Warcraft: EU-Betatest has been delayed!

In the article they simply re-phrased the original news item as to make it sound worse than it is. Of course you CAN put it that way and negative news is much more fun than positive news and of course the company has more interest to make it sound like things are actually going somewhere …. it is just always hard to believe all that crap and I rarely get to see both sides of the news and most people never do because they stick to “BILD” or “Weekly World News” or …..
