Dotcom millionaires visualisation

James — Mon, 10 Aug 2009 00:21:08 +0000

Here’s another very simple visualisation showing a breakdown of the top 10 dotcom millionaires under the age of 30. The original list was here – I thought I’d put a poster together to answer the moans and groans from the “ICT isn’t useful” camp of naysayers. Free to download, and hopefully I’ll be able to put up links to a printing company who have offered to sell high quality prints of my posters soon. Until then, enjoy:

Update: 10/08/09

My friend Elliot says you’re all fools. So am I, if it makes you feel any better, but still… I was showing off my latest creation and he looked at it askance before saying, “RBS made a profit of $20k and this douchebag earns $700m? Does he live in a mountain somewhere?”

That’s right, folks… Zuckerberg’s net worth isn’t quite $700m. Facebook’s turnover is.

To those of you who have already printed this, I apologise, and Elliot says “hahaaaaa!”

Oh, and yes… I was listening to Marley when I made it.

The blog was misleading!

The impact of ICT: Facebook hits 200 million users

James — Mon, 13 Jul 2009 20:42:43 +0000

I’m toying with the idea of making a website devoted to resources specifically geared towards developing thinking skills, and awareness of the wider world… I try as far as I can to avoid the “trivial pursuits” Jamie McKenzie argued so eloquently against. Hell, it’s not as if I work hard enough (cough).

Anyhow, thought I’d share my latest effort comparing Facebook users to populations, which I am well aware is like comparing apples with legwarmers, but a fun factlet nonetheless.

Demystifying abstract terms

One of the problems with a subject like ICT is relating seemingly abstract terms. In a recent discussion about storage & computer memory, I found some of my Key Stage 3 students had little concept of the units of file size. After a little while we established that a kilobyte was bigger than a byte, a megabyte was bigger than a kilobyte, and a gigabyte was bigger than a megabyte, but that was about as far as it went.

As a result, I decided to put together a poster to explain the largest unit of measurement we deal with at the moment, the terabyte. As our school network has 6Tb storage capacity, it’s a nice figure to do some number crunching with.

Using a handful of web-based facts such as Internet traffic in 1993, and my own calculations based on freely available information, I came up with this:

I hope to get this printed out at A1 size using my school’s large format printer and include a dramatic unveiling of the figures in a lesson dedicated to finding the answers to the questions posed. For example, using the Harry Potter point, students would have to:

Find out how many CDs comprise the entire Harry Potter audiobook collection (103 – available from Amazon.co.uk)
How many minutes an audio CD can hold (74 mins)
The minute-to-megabyte ratio of MP3 compression (using 128kbps is roughly 1Mb to 1min)
How many times the entire collection can fit on a 1Tb hard drive (therefore how many gigabytes in a terabyte; how many megabytes in a gigabyte)
