Devoxx 2011 - Day 4

The last full day was again packed with high-end tech stuff before we enter the 10th anniversary party of Devoxx. So I guess, the fifth day gets a bit less blog coverage than the previous blogs. The ConSol posse has some reviews about Akka, JavaFX, HTML-5 and Android again, Play, JMS 2.0 and Clojure for you.

Devoxx 2011 - Day 3

Day 3 and Devoxx is running at full blast now. Rooms are crowded, WiFi breaks down periodically, lanes in front of the toilets and lunch lanes, but nothing will stop the FUN we are having here ;-). There we go with our reviews about the diabolical developer, Play 2.0, Kotlin, JAX-RS 2.0, NoSQL, Phone Gap, HTML5 and the JDK 7 Filesystem API. Please fasten your seat belt for some geeky stuff.

Devoxx 2011 - Day 2

On the second the rest of the ConSol posse joined us : Christoph, Christian and Torsten arrived for the fireside chat. A session format which lacked a bit the tension, but there were some rare highlights like the following joke: Q: “What’s the difference between Ant and Maven ?”, A: “The author of Ant apologized”. The other stuff covered were the ServiceMix combo, Groovy, Spring in the cloud, Infinispan, JDK 7 and Jenkins for Continous Delivery.

During evaluation of the migration of a customer’s Nagios installation to the Shinken monitoring system, i encountered a strange problem. Reading the configuration from a few files (hosts.cfg, services.cfg, etc) took a reasonable amount of time. But as soon as i divided the configuration into lots of smaller files (one directory for each host with several services files within), it took nearly an hour. What happened?

Während des Bootens von Proliant-Servern wird eine umfangreiche Prüfung der verbauten Speichermodule durchgeführt. Entdeckt das Bios dabei Ungereimtheiten oder schadhafte DIMMs, so werden diese auskonfiguriert und der Bootvorgang fortgesetzt. Ob dies bei einem Server vorgekommen ist, zeigt ein Blick ins Integrated Management Log. Dort erscheint dann folgende Meldung:

Event: 26 Added: 03/08/2011 21:01
  CAUTION: POST Messages - POST Error: 207-Memory initialization error on Processor 1 DIMM 6. The operating system may not have access to all of the memory installed in the system..
