Lies, Damned Lies and Benchmarks

This is just an exercise to measure the performance between Sinatra-like libraries in:

• Elixir v0.4.dev (running on top of the Erlang VM R14B03) with Dynamo;

• Ruby 1.9.2 with [Sinatra Synchrony] v0.0.3 (https://github.com/kyledrake/sinatra-synchrony) + Thin;

• node.js 0.4.7 with [express] v2.3.10(https://github.com/visionmedia/express)

Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

• From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
• That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost

Migrating to OS X Mavericks breaks the ngrep utility. Doing:

sudo ngrep -d lo0 -q -W byline port 8080

stopped working where the process exits immediately. I didn't dig into the ngrep code, but was able to find a simple workaround by doing

sudo ngrep -q -W byline -d lo0 '' 'port 8080'

You can call that a lazy hack, but it work!
