example that render things offscreen with gl-react – would love if you find a way to make this use-case less hacky
class AutoCaptureGLThing extends Component {
onRef = exportable => {
if (!exportable || this.exporting) return;
this.exporting = true;
exportable.captureFrame(/* see https://projectseptemberinc.gitbooks.io/gl-react/content/docs/api/Surface.html */)
.then(path => { // oops back to node callback pattern via props callback
this.props.onCapture(null, path);
}, error => {
this.props.onCapture(error);

Troubleshooting with cassandra on Mac OSX El Captain
  • Download the tar.gz of Cassandra from http://cassandra.apache.org/download/
  • extract it in your own ~ wherever it makes sense for you (me it's in ~/bin/)
  • Add the cassandra-*/bin/ to your $PATH in your bash profile (me I need to add /Users/gre/bin/apache-cassandra-2.2.3/bin/)
  • Try to run cassandra.
  • If it runs fine you are done.
  • If you get into trouble with an error like Unable to gossip with any seeds or Fatal exception during initialization org.apache.cassandra.exceptions.ConfigurationException: Found system keyspace files, but they couldn't be loaded!
    • edit conf/cassandra.yaml in the extracted cassandra directory
    • comment the line # listen_address: localhost
  • start the cassandra command again.
