End user applications

[Wolodja Wentland]

Hi all,

I was recently trying to find some applications written in Clojure that are
meant for end users. The aim was to find those that would be interesting to a
user even though the user does not know anything about Clojure or that the
application is written in it.

Given that Clojure is not that young anymore I was a bit surprised to find
only Riemann [0] and Semira [1] out there among thousands of libraries or
development tools.

Can you think of others? What are Clojure's "killer applications" ?

PuppetDB is another:

We use PuppetDB at GOV.UK for host management and reporting purposes.
Nobody else on my team really knows clojure, but nobody has to care
because PuppetDB is self-contained.

getprismatic.com, orderharmony.com, www.rocketli.st are consumer focused apps written in Clojure. FlightCaster is hard to miss.

Hey, just recently I've completed my first full Clojure client
project, the new identity for Leeds College of Music. Some pretty
pictures:

http://flickr.com/toxi/sets/72157630719227308/

The project is a 3-tier system, consisting of:

1) OSX app with custom OpenGL GUI to create & preview new brand assets
2) web app to manage/track render jobs, EC2 instances & generated assets
3) on-demand render farm running on EC2 to render and transcode high
res print & video assets.

The identity is based on a dual strange attractor particle system,
which is computed using OpenCL (approx. 500-800M particles per video
frame). Students at the college can upload their own music via the
render manager web app to create audioresponsive versions of the logo
and embed the generated videos via a custom JS player widget.

Key libraries (incl. some of the best I've ever used):

* JOGL & JOCL -- bindings for OpenGL/CL
* amazonica -- S3, SQS, EC2
* liberator, hiccup, compojure, ring -- render manager API
* http-kit, clj-http -- server etc.
* clutch -- CouchDB
* clostache, markdown-clj -- email templates & documentation
* postal -- email notifications
* timbre -- logging

...of my own (public) ones, but which still largely await some more
TLC before recommended public consumption:

* http://hg.postspectacular.com/simplecl/ - Clojure <-> OpenCL
* http://hg.postspectacular.com/structgen/ - C struct/typedef parser
* http://hg.postspectacular.com/rotor/ - rotating logs

Also, Lein's profile system itself was invaluable for configuring the
different project tiers from a single project.clj (made even better
together w/ the lein-environ plugin).

A big thank you to all the authors!

Best, K.

That has a fair bit of "air-play" in the wild, and has been
trouble-free the whole time. I can probably dig out some numbers from
our marketing department about how widely used it is, if y'all are
interested.

At rewryte.com, we use Clojure for all our back- end data processing.

Sure, but I was rather looking for actual applications that can be downloaded and installed locally. It wasn't really my intention to compile a list of companies that use Clojure somewhere in their web stack (that would simply be a duplicate of the "Clojure in production" thread).

Thanks

Ah, wonderful. This is exactly what I was looking for (self-contained, open source application that appeals to users unfamiliar with Clojure).

Ta!

Overtone is certainly great, but I would rather classify it as a library as you still have to write programs to use it. There might be an independent UI these days that I am unfamiliar with though.

The problem that you have here is that the definition of "end-user".
Overtone allows people with both musical and programming skills to use
both to make noise. These are end-users, albeit a rather narrow
selection.

I'm building a library for the construction of ontologies with a similar
aim. Non-programmers should be able to use it to build ontologies;
programming ontologists should be able to use it to build ontologies
more easily.

End-user? Well, it's not designed for programmers (only), nor for anyone
who cares about clojure. Ironically, when I did the last release, people
here complained about the documentation -- it made the assumption that
the reader knew what an ontology was; a bad assumption for people here.

So, it depends what you mean by "end-user". If you mean "with a GUI",
that's a nice and simple definition.
