'Tcprstat is a free, open-source TCP analysis tool that watches network traffic and computes the delay between requests and responses. From this it derives response-time statistics and prints them out.' Computes percentiles, too

Bayes' theorem, and 'similar statistical analysis', ruled inadmissible in UK law courts (via Tony Finch)

'nobody — almost literally 0% of users — uses the menu bar, and only 10% of users use the command bar. Nearly everybody is using the context menu or hotkeys. So the solution, obviously, is to make both the menu bar and the command bar bigger and more prominent. Right?
Microsoft UI has officially entered the realm of self-parody.' (via Nelson)

Fantastic comparative number crunching on the JC Decaux Dublin Bikes scheme, compared to their other European cities (Brussels, Lyons, Paris, Seville), times of day, busiest stations, rainfall, etc.

'The system demand displayed here represents the electricity production required to meet [Irish] national electricity consumption, including system losses, but net of generators' requirements.

Dublin-based musician Ronan Hession argues that the illegal-downloading bogeyman is vapour with a bunch of persuasive stats

Everything else in the field is either anecdotal hocus-pocus or a decree from Matt Cutts. When you hire an SEO consultant, what you are really paying for is domain experience in the not-failing-at-web-design field.'

wow. fascinating results from social-network cluster analysis of Facebook, splitting up the entire USA into 7 clusters

'View real-time data and statistics from any logfile on any server with SSH, in an intuitive and entertaining way', supporting postfix/spamd/clamd logs among loads of others. very cool if a little silly
