It’s been a busy couple of months…  I’ve left my career at BSkyB to co-found a Data Science startup called TUMRAand have been busy beavering away on developing our products!! I have however updated my parent website https://cutler.sg/ recently, and have yet to consolidate MovableType with my HTML5gasm homepage.  Expect more soon :O)

Ganglia has a great little utility called gmetric that allows you to report on anything you like.  Abusing this feature combined with a simple shell script I was able to get CPU Temperatures from lm-sensors into my pretty graphs on Ganglia. Original credit goes here.  

Changing the ‘niceness‘ of only one type of daemon While recently playing with our cluster during a Terasort benchmark I realised just how dumb it was to leave everything running with the default level of niceness (0).  SSH sessions were timing out, reporting was going haywire, al-sorts of fun. I know the Cloudera CDH3 distribution allows you to set a…

One of the most interesting talks I attended at Hadoop World was by Revolution Analytics.  A couple of months ago they released a set of open-source packages to Github which marries their ‘R’ statistical programming language to the power of Hadoop.  As well as running R programs across Map/Reduce it includes support to work with…

It’s been a few weeks since I last posted… I’ve migrated this site to a new home and done a bit of spring cleaning. You can expect more interesting analysis of social media data shortly. I’ve compiled quite a bit lately just because I started capturing data and then forgot to switch it off! In other news; This site…

Lately I’ve been postulating ways to get some meaningful data out of social media like Twitter.  While half paying attention to a Formula One race in the background on the TV, I twigged on to an interesting experiment.  I generated a Formula One relevant filter to use with the Twitter Streaming API, whereby Twitter would…

Recently I was ranting about Slicehost being assimilated by Rackspace and how bleak its future seems.  I have a few virtual machines hosted by Slicehost and tried out Rackspace to see what I was in for.  Deeply saddened by their service I started looking for a new home. Linode looked promising at first – native…

This post is a bit of a brain-dump detailing exactly how/what/why, if you just want the juicy bits skip to the bottom 😉 I’ve been a loyal user of the Apache Web Server for some 10 years.  Working on everything from custom server modules (in C) all the way through to bog-standard use cases like…

I’ve been an Slicehost customer for years, and I vividly recall that the sign up process went something like this; Sign up in the website and enter billing information (1 minute), Create a simple VM with Fedora (5 minutes), SSH into the machine and start using it (<1 minute), So basically within 7 minutes of…

A couple of weeks ago I migrated my home computer to Fedora 15 featuring the new GNOME 3 user interface among other significant changes.  At first it was quite a struggle to get used to, I almost rolled back to Fedora 14.  After persevering for the first few days it got easier to work with,…

UPDATE:  Google have finally provided a native Linux client, just login to http://music.google.com/ and click ‘Add Music’ to install it. Last week I received a Beta invite for Google Music.  I jumped straight onto it only to meet the message “Music Manager is only available for PC and Mac”.  Being an avid Linux user I…
