Since few months I’m having fun on developing a middleware application with Java 8, Spring Boot (1.5.x) and the Spring Data MongoDb module. Spring Data MongoDb supports spatial data type and it also support GeoJson format, which means you can send a geometry in GeoJson format (point, linestring, polygon, etc…) and Spring Data MongoDb will…

This time I wanted to build up a Cluster for GeoServer. Suppose to have many requests to serve and tasks processed are really high cpu intensive, what you would initially think as first option is to put 2 GeoServers and with a simple proxy balancer switch the traffic 50-50 to each of the 2 nodes. That’s correct,…

Here my new pc. As every respectable nerd there have to be some overclocked stuff. Currently it runs smoothly and silently at 4.0 Ghz :). (Factory Frequency is 3.4 Ghz). The case, the air carbide 540 is huge it doesn’t fit easily on my desk , but the airflow is really impressive. Any high cpu load is cooled in…

Since few days I was searching for a way to disable the editing via keyboard on the really nice RadScheduleView control provided by Telerik.

Since 2 weeks now I’m running the newest version of OpenNMS, the 1.12.1 . There is a really nice improvement that this new release brought: fancy/awesome graphs!! Now they seems more “precise” and even the perceptions of colours give at a first sight an idea of what’s happening: bad or good. In the pic above…

Sometimes it might happen that you need “enriched” notifications from OpenNMS. Suppose you would like to send a notification including an information which is present on the asset view of your node: the Event Translator of OpenNMS is what you’re looking for. At this Event Translator web page you can find the official documentation from…

Since last month I’m studying a nice topic like the “High Availability” on Linux OS. If you have a SLES 11 and a license for High Availability Extension add-on, this guide could be really helpful for a good understanding. The lack of official and well documented procedures it’s really common for these graceless topics, but…
