Remove all Docker images filtered by `pattern` except latest `n`
#some grep pattern
pattern=192.168
# save latest n images
n=1
# check first (?):
# docker inspect -f '{{ .Created }} {{ .Id }} {{ .RepoTags }}' $(docker images | tail -n+2 | sed 's/^\([^ ]*\) *\([^ ]*\) *\([^ ]*\).*/ \1:\2 \3 /' | grep $pattern | cut -d' ' -f3) | sort -r | tail -n+$((n+1))

Blessed GC settings for big servers
# Base settings and GC logging
-server -XX:+AlwaysPreTouch # First should be default, but we make it explicit, second pre-zeroes memory mapped pages on JVM startup -- improves runtime performance
# -Xloggc:gc-%t.log # CUSTOMIZE LOCATION HERE - $path/gc-%t.log -- the %t in the gc log file path is so we get a new file with each JVM restart
-XX:NumberOfGCLogFiles=5 -XX:+UseGCLogFileRotation -XX:GCLogFileSize=20m # Limits the number of files, logs to folder
-XX:+PrintGC -XX:+PrintGCDateStamps -XX:+PrintGCDetails -XX:+PrintHeapAtGC -XX:+PrintGCCause
-XX:+PrintTenuringDistribution -XX:+PrintReferenceGC -XX:+PrintAdaptiveSizePolicy # gather info on object age & reference GC time for further tuning if needed.
# G1 specific settings -- probably should be default for multi-core systems with >2 GB of heap (below that, default is probably fine)
-XX:+UseG1GC
-XX:+UseStringDeduplication

Steps for Integrating Jacoco in IntelliJ IDEA
  1. Integrate the dependency and plugin sections to relevant parts in your pom.xml from the pom.xml_fragment file below.
  2. Run "mvn clean package" to generate the results
  3. In IntelliJ, Select "Analyse -> Show Coverage Data..." and pick your Jacoco output file. This should be the path specified in the plug-in config i.e: ${basedir}/target/coverage-reports/jacoco-unit.exec

Output should be displayed in the IDE and you should also have the classes overlayed with test coverage.
