Node wasn't letting me install new modules throwing at me an EACCESS: permission denied error every time.

This did it, it can work in other use cases as well, this one lets you install global packages, but you can change the directory to whichever:

$ sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}

Bindings

<input type="text" [(ngModel)] = "componentPropertyName" placeholder="name">

The [(ngModel)] basically means that if I update the textbox, it will update the target variable (in this case componentPropertyName) and reflect it back in the screen.

• With Docker 1.8.0 shipped new log-driver for GELF via UDP, this means that the logs from Docker Container(s) can be shipped directly to the ELK stack for further analysis.
• This tutorial will illustrate how to use the GELF log-driver with Docker engine.
• Step 1: Setup ELK Stack:
  • docker run -d --name es elasticsearch
  • docker run -d --name logstash --link es:elasticsearch logstash -v /tmp/logstash.conf:/config-dir/logstash.conf logstash logstash -f /config-dir/logstash.conf
  • Note the config for Logstash can be found at this link
  • docker run --link es:elasticsearch -d kibana
• Once the ELK stack is up now let's fire up our nginx container which ships its logs to ELK stack.

• LOGSTASH_ADDRESS=$(docker inspect --format '{{ .NetworkSettings.IPAddress }}' logstash)
• `docker run -d --net=host --log-driver=gelf --log-opt gelf-address=u

Aggregations

Really should checkout the Elastic Aggregations documentation, it's great:

In short, the format is something like this
