Only do this if you understand the consequences: all node programs will be able to bind on ports < 1024
sudo setcap 'cap_net_bind_service=+ep' /usr/local/bin/node
Important: your node location may vary. Use which node to find it, or use it directly in the command:
Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
$ python -m SimpleHTTPServer 8000

| recipe_path = ARGV[0] | |
| if recipe_path.nil? | |
| STDERR.puts "usage: chef-apply RECIPE_FILE" | |
| exit 1 | |
| end | |
| recipe_path = File.expand_path(recipe_path) |
Operation: Decouple whisper from graphite.
Method: Create a graphite function that does a date histogram facet query against elasticsearch for a given query string for the time period viewed in the current graph.
Reason: graphite has some awesome math functions. Wouldn't it be cool if we could use those on logstash results?
The screenshot below is using logstash to watch the twitter stream of keywords "iphone" "apple" and "samsung" - then I graph them each, so we get an idea of popularity. As a bonus, I also do a movingAverage() on the iphone curve to show you why this is awesome.
