REST Ideology & Rants

I am getting frustrated by the number of people calling any HTTP-based interface a REST API. Today’s example is the SocialSite REST API. That is RPC. It screams RPC. There is so much coupling on display that it should be given an X rating.

REST APIs must be hypertext-driven

Roy Fielding writes a PhD dissertation describing the architectural style of the World Wide Web. He coins the term ‘Representational State Transfer’ (REST) to describe it – after all, if you’re going to talk about something, you need to give it a name. Somehow, in a semantic shift of epic fail proportions, the term REST has also come to mean something completely different to most people, a ‘style’ of writing web services. This style has no agreed protocol.

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

Welcome!

For feedback or suggestions, please send a tweet (@dideler). Gist comments don't notify me. Pull requests aren't possible with gists (yet), so I don't recommend forking because then I can't easily get the change.

Starring this gist will give me an idea of how many people consider this list useful.

• OpenStrategy - kinda like this list, but much nicer presentation
