I am saddened beyond words to hear of the death of Ian Murdock. Ian was the founder of Debian and the first secretary of the Open Source Initiative, among many other things. I got to know him when we both worked at Sun Microsystems and found him a brilliant man, capable of insight and charm.

Many of us were exceptionally concerned by his tweets on Monday reporting he had been brutalised by the police and saying his career was ruined. I am sure there is much to learn and tell, but the post by his current employer (Docker) rightly asks that we respect his family's grief  so I suggest avoiding speculation here.

Goodbye, brilliant friend.
Dear friends and members of the open source community, It is with great sadness that we inform you that Ian Murdock passed away on Monday night. This is a tragic loss for his family, for the Docker…

Interesting learning: It is possible to use 32 bit references in a 64 bit #java  JVM.

How to extract RGB color channels from an Image in #javafx :
Suppose you have an Image and want to extract the color channels for red, green and blue into three new images. A straight forward way would be to create a new empty image with the same size as the source image, iterate the source image pixel by pixel, convert the pixel color of each pixel and ...

While playing around with Borders in JavaFX, I came across the term "9-patch scaling technique", and I wondered what that actually means. First of all, "9-patch" means that a rectangular area is divided into 9 areas (patches) of possibly different sizes as shown in the following image: ...

This does not make sence at all. As a java programmer you do not write code for the architecture of the cpu. The only way to reduce the memory footprint is write good code. There are good books about this topic e.g. Efficient Java.

“Jigsaw needs more time”
 ·  Translate
Oracle kann den geplanten Release-Termin von Java 9 im September 2016 voraussichtlich nicht halten. Offenbar benötigt das Modularisierungsprojekt "Jigsaw" mehr Zeit, heißt es in einer Mitteilung an die Community.
