Hi I am new to the whole Rails/Ruby world as having come from a MS .NET background, but I have followed the Depot example in the Agile Web Dev. with Rails book with relative ease.

Hello, I am almost new in R, so perhaps my question will be silly. I try to use R for analyzing capture-recapture data in epidemiology. A cancer registry has different sources of patients. We know in each list, patients already known in all other list. The aim is to use capture-recapture models for estimating the number of patients unknow of all the sources.

Hello, I am trying to create a container image which will build Java software with Maven and Java 11 (rather focussing on CentOS 8 here). When installing 'maven' with yum, 'java-1.8.0-openjdk-devel' is installed as a dependency.
