Signing a Java Jar

Blogging this because it took far too long to figure out and because the documentation is spread across too many pages and isn't at all clear.

Generate some signing keys.

keytool -genkeypair -alias USERNAME -validity 1000 -keystore FILENAME.keystore

Answer some questions. The resulting FILENAME.keystore file must be kept private. This generates a key that's valid for at least 1000 days. The java docs have more information.

Installing intl for PHP on OS X

Pecl will only try to install PHP extensions in /usr. But OS X's security model prevents that. This work-around works around the problem and installs extensions in different spot.

UTF-8 Everywhere

Apache, PHP, and web browsers default to ISO-Latin-1 (aka latin1). MySQL defaults to latin1, with the latin1_swedish_ci collation.

Run tests when they are saved

Python's watchdog module includes watchmedo, a command that watches files or directories. I like to use it to automatically run a test when the test is saved.

$ watchmedo shell-command --patterns="*.py" --recursive --command='echo "${watch_src_path}"; python "${watch_src_path}"' tests/

Hint: $ python3 -m pip install -U watchdog
