stoerr / CharsetStress.java
Last active Feb 12, 2020
For testing purposes: generates various test strings with unusual characters which can be used to detect character encoding problems. Caution: this currently covers only relatively common stuff - it does not yet lead into the deeper realms of UTF like substitutes, right to left, Kanji, characters outside of 16 bit.

This JSP lists all threads with stati as configured in a checklist, optionally whose names match a specified regex.
If two threads have the same stacktrace, they are shown together and the stacktrace is printed only once.

Automatically include ticket number from branch name into git commit messages
View prepare-commit-msg
#!/bin/bash
# If you use branch names with JIRA ticket numbers in them, e.g. feature/ABC-4324-do-something,
# this includes automatically the ticket number (ABC-4324) at the start of the the commit message.
# This way, it's later easy to see which change was done for which ticket, without any manual effort.
# You need to copy or link this file into .git/hooks/prepare-commit-msg
# You can customize which branches should be skipped when prepending commit message.
