10gen recently announced a cloud-based backup service designed for MongoDB. Here's a slice of the announcement . . .
Here's a simple step-by-step tutorial for getting started with Redis on Ubuntu
When you make use of (some of the) Amazon services there is a big chance S3 is one of them for the storage of files, be it temporary or more permanent.
Server virtualization has been a great set of technologies to reduce our capital expenses and some operating expenses by consolidating a larger number of virtualized server workloads in a smaller footprint . . .
PHP has several built-in ways of serializing/unserializing data. The most cross-platform is json_encode; pretty much every programming stack can JSON decode data that . . .
This screencast by Michael Kennedy shows you the stark contrast in simplicity between an application using a relational database and one using a document database such as VoltDB, MongoDB . . .
Given that one of my most widely read blog posts is still MongoDB's Write Lock, I decided that my blog readers would also be interested in the quantitative comparison as well.
I found Redis to be a very interesting option to Memcached for use as caching layer:
A lot of our users upgrade from single-node databases to replica set clusters without fully understanding how their driver, and therefore their application, will react to failover
Aaron Morton, DataStax MVP fo Cassandra, presents this 1-hour introduction to Apache's NoSQL solution.
Here's a quick tutorial for adding documents using Java Couchdb4j.
I’ve been trying to see if I can match some of the football stats that OptaJoe posts on twitter and one that I was looking at yesterday was around the number of red cards different teams have received.
First of all, it is a short book and you can run through the pages fast. As the title says, the book is really an introduction to NoSQL databases.
Applying the lessons from the leveldb codebase isn’t going to be a straightforward task. I already discussed why we can’t just use leveldb directly, so I won’t go into that.
PostgreSQL has very good support for arrays of other data types. One can have nested data types where an attribute of a relation stores an array of tuples . . .

Here's a 1-hour webinar from NuoDB that covers how common enterprise strategies for scaling fall short, as well as how a CDMS like NuoDB enables innovation and cost reduction.
Is your database holding back your application? Find out how we at RightScale use NoSQL databases such as Cassandra . . .
In summary, I am quite happy that I spent the time reading all of this code. The LevelDB codebase is really simple, when you grok what it actually does.
First and foremost, it is important to understand that the SDK wraps and extends the functionality of the spymemcached (called "spy") memcached library.
I like reading interesting code bases. And in this case, I have been reading through the leveldb codebase for a while.
Here's a quick 3-minute tutorial that will help you understand the limitations of commonly used distributed file systems.
The bottom line for any sysadmin is to keep the database and in case of Couchbase, keeping the cluster up and running 24x7.
Last year, a lot of folks asked us if they could use MongoLab’s admin tools on databases not hosted with MongoLab.
Today: Ubuntu 13.04 Raring Ringtail, safety in Rust 0.6, a clean architecture framework, and Ruby on Rails creator David Hansson on when empathy can be insulting. Plus: a 14-year-old McDonald's hamburger.
