(Ruby) Watchr config for use with PHPUnit

Thu, 31 Mar 2011 14:28:22 GMT

A simple [Watchr](https://github.com/mynyml/watchr) config for running PHPUnit tests. This will run a [Pake](https://github.com/indeyets/pake/wiki) task called "test" and ring the system bell if the task fails. *Ringing the system bell* is especially nice when running inside a GNU Screen session. *Installation* To install you need [RubyGems](http://rubyforge.org). Then type: sudo gem install watchr

(Bash) bash: how to start a service and wait until it\'s up

Thu, 28 Oct 2010 14:02:26 GMT

Sometimes you need to start a service that takes a while to spin up. Solr and Selenium-RC Server, for instance, can be unavailable for several seconds after the command to start them is issued. Using Netcat, it's easy to poll-and-wait until a newly-started service begins listening on its proper port.

(Bash) verify a service is up and running with netcat and Hudson

Sun, 03 Oct 2010 16:11:56 GMT

Use the `-z` option to netcat so you don\\\\\\\'t have to bother with piping input into the port once opened. All you want to know is if the service is up!\\r\\n\\r\\nThen, if you are running this checker inside of Hudson, you need to set the BUILD_ID env var to something abitrary like BUILD_ID=dontKill\\r\\n\\r\\nKludgy, but [it works](http://issues.hudson-ci.org/browse/HUDSON-2729?focusedCommentId=127805&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_127805)

(Bash) sendmail without writing a file

Tue, 21 Sep 2010 00:22:32 GMT

Usually you see sendmail invoked with `sendmail me@example.com < file.txt` What if you're scripting, and don't feel like writing a temp file for every email message?

(Bash) howto create/change SVN externals (link an SVN repo to another path in the repo, or to another project entirely)

Sun, 21 Mar 2010 13:05:06 GMT

Thu, 11 Feb 2010 14:59:31 GMT
