The conclusion was clear: among primates, monogamy was always preceded by one thing and one thing only: infanticide by males. Here, we report the video-captured infanticide on a grown nestling at 17 days after hatching by a mated male in a sparse population of Japanese Bam Swallow (Hirundo rustica gutturalis).
We frequently create a class to do nothing but hold data. In such a class some standard functionality is often mechanically derivable from the data. In Kotlin, this is called a data class and is marked as data: data class User(val name: String, val age: Int)
The ulimit and sysctl programs allow to limit system-wide resource use. This can help a lot in system administration, e.g. when a user starts too many processes and therefore makes the system unresponsive for other users. Code Listing 1: ulimit example# ulimit -a. core file size (blocks, -c) 0. data seg size (kbytes, -d) unlimited.
