This weekend we completed a major update to Yacapaca. Most of it is “under the hood” stuff to help us cope with Yacapaca’s increasing popularity, but there are eight changes to the interface that you may need to know about. Here they are:
I’m not in complete agreement with the definitions here, but I do broadly agree with the sentiments expressed. Look out for the lovely juxtaposition of the Socrates quote and the “Fire extinguisher inside building” sign.
[Update: I found one source that attributes that quote to Plutarch, and another that says it was Plato. So it looks like it was really made up by someone who sussed it would get more credence if he claimed it came from a Greek philosopher, but he was a bit inconsistent about which one. Feel free to add your own theory in the comments, if you have a credible source.]
Thanks Krystie for pointing me to this fantastic 4-minute video from Yr 2 teacher Stacey Hibberson at Mount Beauty Primary School.
If only I could explain Yacapaca that succinctly.
Last month, I used swine flu as a test-case for Wolfram|Alpha. This month, with my next-door neighbour’s school already closed due to the ‘flu, I’m getting more concerned about the pandemic itself.
Here are the charts. You can see from the shape that the previous straight line has now become an exponential.
Notice how the two curves have about the same shape. The ratio of infections to deaths has remained approximately constant at 0.5%. Before you say “oh, that’s only in Mexico” let me give you the figures for the USA; 27,698 confirmed cases and 127 deaths. That’s 0.46%.
In previous ‘flu pandemics, pretty much everyone in the world has been infected in the end. So, let’s do the arithmetic on what that means:
What’s really bugging me is the complacency of the authorities, here in the UK and in many other countries. Because there have been relatively few deaths so far (Wolfram says 279 worldwide) the media is putting out the message that this is just a scare, and it will go away if we ignore it. Alternatively, the notion is promulgated that now the genii has escaped from its Mexican bottle, there is nothing we can do, so why worry?
Neither is true. The Chinese government has shown that this major threat can be effectively countered. They are using mandatory quarantine to buy themselves time whilst a vaccine is developed. Even if they can only buy themselves six months, the vaccine should be ready, in bulk, before a significant death rate kicks in in China. At the cost of inconveniencing a few hundred people for week or so each, they may be saving as many as 5 million lives.
So, what can you and I do to compensate for the incompetence of our elected representatives? We can insist on the maximum possible quarantine for any suspected case in school. Faced with clear evidence that one infected child in 200 is likely to die, fear of litigation may succeed where fear of infection failed.
