Out of curiosity:

Who has written Haskell & deployed to production in the last 24h and if yes for what kind of app?

I know Amsterdam startup http://www.silk.co has their entire backend written in Haskell. I'm not sure they deploy in weekends though.

Their CEO Salar told me that that, among other things, it gives them a hiring edge. People move to Amsterdam from all kinds of places just so they can write Haskell professionally.

No we usually don't deploy in weekends. Only if we break stuff just before the weekend. :)

Indeed! So you didn't deploy Haskell in the last 24h so you don't count :-)

As someone who moved to Amsterdam to write Haskell (and JavaScript) for Silk, I can confirm that the combination of a beautiful bike-friendly European city, a Haskell backend, and exceedingly cool co-workers makes for a very pleasant working environment.

I'm off on other adventures now, but I have no skepticism about deploying Haskell in production. Yeah, it's still a bit obscure, but if you're looking for smart and eager programmers, Haskell is good bait.

My impression is that there's nothing wrong with Amsterdam. Nice and liberal under a good state.

Not in the last 24h, but I pushed to production on Friday. We use Haskell at IMVU to power some of our web services and persistent stateful servers like the matchmaker.

I work for http://fynder.io - our entire backend stack is Haskell (libraries, PostgreSQL interface, email sending daemons, API server)

I have, for data-flow analysis software.

Haskell gets used in the oddest places, where one of two things is true:

    1. Nothing else works (with reasonable LOC *and* performance)
    2. The safety of an advanced type system is required

I'm not optimistic about Haskell appearing anywhere else for the time being, so I think it will stay an "exotic" language for awhile longer.

Facebook’s site integrity rules are written in Haskell (using Haxl: https://github.com/facebook/haxl) and are deployed every few minutes.

We use Haskell at SimplyRETS (https://simplyrets.com).

The core api service is written in Yesod and various other components are written in Scotty and WAI.

We use Haskell at https://www.frontrowed.com/ for most of our web applications, internal tools, email senders, API etc.

The Lamdu project I'm working on is in Haskell.

Our build system for a large C project at work is written in Haskell.

Various other tools we use (cgrep, resolve-trivial-conflicts, etc) are in Haskell.

Haven't pushed to the repo yet, but https://github.com/bluepeppers/highhockwho is my contribution :) Little tool to poll the docker daemon and push records to etcd in a skydns compatible format. In production, and seems to be fairly stable so far.

Ad traffic anit-fraud platform (api servers, data mining workers)

I recently launched http://geohangout.com. The entire backend service is written in Haskell (Yesod).

Our core services at https://circuithub.com is built on Haskell.

My company, FanJam.com, is built using Haskell for our backend stack & Ember on the frontend
