Lately I have been reading a lot of blog topics about big sites(facebook, twitter, digg, reddit to name a few) using cassandra as their datastore instead of MysqL.
I would like to gather a list of resources to learn using cassandra. Hopefully some videos or podcasts explaining how to use cassandra.
My list
Twissandra - Twissandra is an example project, created to learn and demonstrate how to use Cassandra. Running the project will present a website that has similar functionality to Twitter
WTF is a supercolumn - WTF is a SuperColumn? An Intro to the Cassandra Data Model
I hope there are resources to watch howto use cassandra.
Many thanks,
Alfred
I found these articles really helpful coming from the relational world:
http://www.sodeso.nl/?p=80
http://www.sodeso.nl/?p=108
http://www.sodeso.nl/?p=207
Right now the docs available for cassandra is limited in some places. I've been watching the Cassandra user and dev email list like a hawk. That seems to be where most of the FAQ's live.

IndexedDB API on node.js will be very useful for some app.
Why IndexedDB is not available in node.js?
IndexedDB API does not depend on DOM, even though it does use some DOM error and event style.
It's possibly because IndexedDB is part of a different body of standards. Node.js is just ECMAScript (via Google's V8) along with their own API. Also, it may not help that IndexedDB is still in "Draft."
But, more likely it's for the same reason Node.js doesn't offer any database drivers: it's not trying to solve those problems. It's just trying to offer the APIs that assist someone who does want to solve and implement them.
And, for that, it appear at least one such project has already started: indexeddb-js. But, also have a look through IndexedDB in the NPM Registry.

I need to choose an open source BPEL engine for my work. I'm new to BPEL and I've never worked with any BPEL engine. Which engine would you recommend me that is easy to configure and use for a begginer? Brief explanation but I really have to experience at all.
We use Apache ODE at work, and it works fine. The project support we have via mailing lists is enough for us.
I used Oracle's BPEL engine about two years ago. It was both a nightmare to configure, and fairly half-baked in terms support. Even their example code didn't work properly. Things may have changed since then.

I am planning to use cassandra and graph database in my spring web project. After googling i found some open source graph database. Actually i was looking for some open source graph database that has good support of cassandra and so i found titan graph database. It seems good but its new and don't know how much efficient it is for real world application that has huge data and read/write operations.
So i want to know that
1. Is there any more cassandra supported graph database?
2. Is titan good enough for real world web application with huge data and read/write operations?

I am looking for a way to get some sort of monitoring, statistic or management data out of a node.js server instance - not sure what to search for or where to start. Any advice appreciated.
Stats would be requests processed (if applicable) - number of connections and so on.
Don't know if it will fit your needs, but you can try to look at node-monitor. Also Joyent is doing some advanced real-time performance analysis stuff, but it's probably only for their cloud services.
Nodetime can monitor different metrics, such as HTTP Response time, CPU time, OS Load, etc. It is also possible to set up email Alerts based on these metrics. More in the blog post Monitoring Node.js Application Performance.

I need a site search engine to provide search for my members-only content. I've previously used Fluid Dynamics Search Engine but was wondering if there was anything that's been more recently updated.
Needs to index content via site crawling as opposed to filesystem crawling as all content is in a database. Also needs to run under FreeBSD / Linux.
Yes, sorry, not programming... but this is the best place to get great answers!
Solr from the Apache Lucene project might be of interest to you.
Another excellent one is Xapian.
Sphinx should be pretty good as well:
