 - Apparently Google announced last year that they plan to [discontinue the shortner and transition to Firebase Dynamic Links in March, 2019](https://developers.googleblog.com/2018/03/transitioning-google-url-shortener.html), so maybe this is related...
 
+- Very interesting discussion of methods for [running Tomcat under systemd](https://jdebp.eu/FGA/systemd-house-of-horror/tomcat.html)
+- We can set the ulimit options that used to be in `/etc/default/tomcat7` with systemd's `LimitNOFILE` and `LimitAS` (see the `systemd.exec` man page)
+  - Note that we need to use `infinity` instead of `unlimited` for the address space
