Cassandra vs MongoDB vs CouchDB vs Redis vs Riak comparison :: KKovacs

Cassandra vs MongoDB vs CouchDB vs Redis vs Riak comparison :: KKovacs.

This is a great summary of a few major players in the NoSQL space.  It doesn’t go in to too much detail, but it’s pretty fair to each one.  I especially like the use cases he outlines for each.

Migrate MySQL to Homebrew MySQL

Think about what you are doing before you do this. Don’t be stupid.


> cp -R /usr/local/mysql/data /usr/local/var/mysql
> brew install mysql
> cp /usr/local/Cellar/mysql/5.1.51/com.mysql.mysqld.plist ~/Library/LaunchAgents
> launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist
**optional** > rm -rf /usr/local/mysql


A new kind of socially-biased search engine: Blekko

A new kind of socially-biased search engine: Blekko.

This idea of a simple query language that actually is geared towards normal people is interesting.  SQL was supposed to be that way back when, but no one today would ever claim that a search engine that exposed SQL to users would be better for the masses.  But a simpler version could have some really awesome broad impact in other areas.  As people become more comfortable using semi-structured queries we can use them in our own web apps without extensive education or making them “advanced features”.  I don’t know if Blekko can succeed, but if they can I think the web will benefit in some interesting ways.

DataSift – Tuning the Social Web

DataSift – Tuning the Social Web.

Wow, this is really interesting.  I’d love to see what kinds of tracking you could do with something like this.  If it can actually do what they claim it can do this would really expose the aggregate data that is living in twitter.  Heck, the fact that they have a sentiment analysis filter they are making part of this is exciting on its own.

Google Wave: why we didn’t use it

Google Wave: why we didn’t use it.

I really am disappointed that Google Wave has failed.  I think the Ars article does a good job of summarizing why it didn’t really take off despite the best press you could ask for not to mention Google backing it.

I’m still hopeful that the underlaying protocol can still be salvaged in some alternate clients.  It really would be interesting to see it reanimated in a different form by someone else.  Even if it were just added as a new account type in Mail.app or iChat and literally only provided feature parity with that tool initially, that might be a more logical progression to introducing what should be a more powerful and flexible communication protocol.  This will also give users a better understood starting point and we can more gradually figure out what people what to be able to do and how they want to do it along the way.  The fully baked solution the Google’s implementation provided really didn’t enjoy much user feedback to influence its development until way too late in the process.
