I am trying to find the different kinds of syntax I can give in regex type of query through kibana, but I was not able to find any information on this.
I am running logstash and elasticsearch in the backend.
Any answer or example will be helpful.
so any regular expressions are valid in grok as well. The regular expression library is Oniguruma.
I took this from the logstash docs online.
Also from [a Google Groups post]:
Kibana is a web interface which stay in front of ElasticSearch: to understand
the query syntax you have to know something more about Apache Lucene,
which is the text search engine used by ElasticSearch.
Here's a small tutorial about the query styles you can use with Lucene and
by inheritance with your Kibana web interface:
http://www.lucenetutorial.com/lucene-query-syntax.html This link is dead, I'm not sure but this might be an adequate replacement. (I've saved it into wayback machine as it keeps dying...)
See also the official Lucene Query Syntax documentation.

Perhaps there is a definitive tutorial or blog describing what I'm looking for, but I haven't seen it. And being new to Django, I'm really looking for a proper way to both set up a VPS and deploy the project to it ... the latter in a repeatable/sensible way as the project evolves.
Here is what my project looks like:
Using Django 1.6.2 + Postgres
Project structure is essentially what is described here
Static assets delivered locally in development need to be uploaded/delivered from S3 in production
My VPS is a basic Linode running Ubuntu 13.10
I would say Test-Driven Web Development with Python is a good one. It's mostly focused on TDD, but it's really good at covering the basics of Django as well. Chapter 8 talks about deployment and is pretty thorough.
EDIT:
Saw that that book doesn't use S3 for static files, so I'd recommend this blog post for dealing with that.
This article: How To Install and Configure Django with Postgres, Nginx, and Gunicorn has some great instruction on getting the VPS setup, minus the S3 assets.
For repeatable deployment do some research on fabric.

I want to create a new service and I need to find a secure cloud storage with client-side encryption. The service needs to be accessible with an API or a SDK or something like that.
I made some researches and I found Mega. Do you know another?
Is there an opensource solution to construct this kind of cloud?
Thanks in advance for your answers.
All cloud have data storage like.
Amazon :- SQS,S3,DynamoDB,RDS etc.
Azure :- Blob Storage, DBMS , Table storage etc.
all these storage can be access by API.
you can implement data encryption like Hashing, Symmetric, Asymmetric at client side before storing the data into cloud storage.
I work for Adrenaline Mobility. We're a new entry into this area, but that's exactly what we do. (Sorry for the promotion, but it's quite relevant). We provide secure storage (client side encryption), credential management (login / signup / password reset), messaging (end-to-end encrypted messages between users, devices, etc). Our architecture is designed so that you don't need to trust us, or our storage backend.
Feel free to email me at murph#adrenalinemobility.com if you want to discuss what we can do for you. We're pretty flexible and willing to work with you.

I have a C++ program, and I want to make it as a web service listening to http request. I am a newbie to web development. Could some one give me a guild to tools/library/APIs that can help me build it. I know Java program usually restlet. What is the equivalent of restlet for C++?
I would recommend C++ web toolkit
http://www.webtoolkit.eu/wt
or
cppcms.sourceforge.net
The old, classic way to make existing C/C++ executable available on the web is through CGI. A web server that supports CGI can be configured to interpret an URL as a reference to a CGI script that can be directly your executable or a simple wrapper around it. The web for fields are provided as standard input and the program's output becomes the server response.
I am working on something similar in Python and I am also newcomer on this field. You might be interested in sockets, see: http://goo.gl/r6X4u, http://goo.gl/enffd
The QxtWeb module provides tools for creating web services using Qt.
Also, if you are using Visual C++ then here is an introduction how to create web services.

The Google Web Search (SOAP) API was deprecated in November of last year, having been discouraged for a long time previously.
I noticed there exists the new Google Custom Search API, but this seems only for creating site-specific custom searches. So, is there currently any API solution for searching the entire web? Either using Google Custom Search or some other API?
Unfortunately, your options are now very limited. You can either use the Bing API (which is not known to be too reliable and often has different results compared to a regular Bing search) or try Yahoo Boss (paid)
Actually, the custom search API will do what you want -
After initially creating your custom search engine, you CAN go back into the control panel / websites link on the left side, and just remove the domain that you were forced to enter when you created the custom search engine.
Once that's done, bingo! you're searching everything, instead of just a site: search
