What is the best way to access data from Graphite render API?
https://graphite.readthedocs.org/en/latest/render_api.html#data-display-formats
Is there a JVM compatible client implementation?
Or there is a possibility to retrieve this data using some other API?
I do realise that the format is self descriptive and it is not a rocket science, but it would be great to reuse and contribute rather than writing from scratch.

The render api, as you mentioned, allows the following variables along with the API call-
&format=png
&format=raw
&format=csv
&format=json
&format=svg
For implementations such as , you can make straightforward curl calls like:
curl "http://graphite.com/render/?target=carbon.agents.host.creates&format=json"
The call would return:
[{
"target": "carbon.agents.ip-10-0-0-111-a.creates",
"datapoints": [
[4.0, 1384870140],
[1.0, 1384870200],
[18.0, 1384870260],
[0.0, 1384870320],
[4.0, 1384870380],
[12.0, 1384870440],
[3.0, 1384870500],
[7.0, 1384870560],
[8.0, 1384870620],
[null, 1384870680]
]
}]
Since it is this straightforward, therefore it'd be pretty lame to implement something just for making curl calls. What the community has done is that they are using these as fundamental building blocks for custom frontends, querying scripts that alert, nagios plugins etc.
Is there something more specific that you are looking for?

I am new to StackOverflow so please do correct me if I need to provide any more information.
I am trying to integrate an anomaly detection into the PostgreSQL database system by plugging into its backend.
I would like to know if there is any place where I can find extensive back-end coding or integration examples. I am looking at papers regarding this topic and, so far, I have found a few which talk about the methods that the queries are classified and used for anomaly detection.
If you do know about any websites which might help me, please do provide links to the sites.
Thanks!!
Look for "hooks" in the PostgreSQL source tree. Studying the source of the auto_explain and pg_stat_statements contrib modules, which track query execution, will show you the way.
The source is its own book: it is well-documented and interspersed with README files that explain the design.

I like the idea of relishapp.com, i.e. that you have Cucumber / Gherkin features and you generate "living docs" from them. However, the Relish SaaS is awful.
I'm looking for an alternative. Ideally self-hosted Open Source like Sphinx, but I'm not completely opposed to SaaS solutions. Especially Sphinx would be great as I could combine it with other docs and use readthedocs.org for deployment.
So the question is: What would be the easiest way to generate HTML docs from Gherkin features?
There is one more option Cukedoctor https://github.com/rmpestano/cukedoctor
You can host within company network using SimpleHTTPServer ( http://2ality.com/2014/06/simple-http-server.html )
I've used yard-cucumber to do that before. It worked out pretty well.

I recently felt the urge to generate documentation for my little project. I thought it would be fairly easy since I had a set of nice docstrings. Turns out the whole process is much more complicated in python 3.1.
Here's what I tried:
epydoc: Fails because it's for python 2. 2to3 didn't solve the problems
pydoc: I can't find any information how can you generate documentation for your own modules, seems like a server for reading python docs offline
sphinx: Most promising so far, I have built it from their repository however it fails with a very cryptic error message (jinja2.exceptions.UndefinedError: b'b"\'sphinx.jinja2glue.idgen object\' has no attribute \'next\'")
My question is: what should I do now? Are there any other non-commercial documentation generators that work with python3?
Apparently in Jinja, something is doing X.next(). In Python 3 that's next(x) instead. It should be a simple fix.

Does anyone know if there is something like a Limewire API? I need to be able to make Limewire download files programmatically.
EDIT: It seems Limiwire doesn't have an API. Is there any other Gnutella P2P cliente that does?
I suppose focusing a little more upon your requirement, you've got the Gnutella downloader service/class/package API thing.
http://wiki.limewire.org/index.php?title=Gnutella_downloader
It allows you to query and download direct to the network.
Then extending that idea - you have jTella, API source for Gnutella network.
http://sourceforge.net/projects/jtella/
Unfortunately, there is not. Also, unfortunate: the source code is terribly difficult to read/modify. If, however, you're up to the challenge, then you can simply write your own application on top of limewire-core, which is seperate form the GUI.
Not sure about a true api - but I found this by googling your title:
http://wiki.limewire.org/index.php?title=Javadocs
Seems to be built in Java. Entire set of packages seem to be there too.

I'm writing an XML-RPC service that will be consumed by third parties and was wondering what the best way of documenting it would be.
As far as I can see, XML-RPC doesn't have any equivalent to SOAP's WSDL to provide a description of the service, so presumably it's something I will have to document by hand?
So far I've come accross examples such as that found here and here where documentation basically consists of an example call with place holders for data.
Is there any better method than this that I'm missing?
Thanks.
Check out XML-RPC Introspection. It is about the closest thing to a standard that you are going to find. XML-RPC does lend itself to simple documents of input/output descriptions. If you want something that can be processed programatically, then implement or enable introspection.
