Comment Tree Bog (Score 5, Interesting) 167

Best and simpest idea for a toilet I've seen is the tree bog. Its a raised platform over an enclosure space fenced off with chicken wire. Around the bog you plant willow or other greedy trees which rapidly consume the nutrients, effectively turning the poo into biomass. Aerobic decomposition has advantages over anaerobic decomposition and there is no smell if you use a layer of sawdust. The whole thing requires no maintenance as the poo decomposes very quickly. Not good for urban situations but ideal in rural environments.

Comment Distance between the eyes does not change much (Score 3, Interesting) 215

A while back I did some work looking at how people faces change with age for a medicinal application. One quite surprising thing is how little the distance between the eyes actually change, quite young children will have the the same distance as adults. On the other hand noses keep growing throughout life.

Comment Sexual Discharges (Score 1) 484

Have a look at Old Testament > The Law > Sexual Discharges. NSFW. Which starts with the line, 'When a man ejaculates semen...'.

Now in its original context I've no problem with the written version, entirely in keeping with the spirit of the book. That section was never intended to be illustrated, indeed the illustrations go against the moral spirit of book. Its intended as book of rules of conduct not as a spectacle of images to be gawped at. I'm generally in favour of using illustrations to help interpret books making them more accessible. Here its just inappropriate and Sam's Club is entirely right to ban it.

Later in the same section Leviticus 15:28-15:30, the bibles advocating the large scale slaughter of doves. Apparently women should sacrifice two doves or pigeons eight days after the end of her period. So thats 24 doves a year. Its a good thing all christians don't follow this as we would very soon rid the world of doves. I now know what I'll ask the next time the Jehovah Witnesses come knocking on my door.

So far, we have thought of places like the Very Large Array in New Mexico and Fermilab in Illinois. Any suggestions?"

But didn't we all start by writing some spaghetti code. Before we can teach good programming design they need to experiment with a print statements, and maybe a loop and an if statement. These constructs are all translatable between languages. This is really a very early stage, they are getting to grips with basic algebra at that age, don't expect too much from the average student.

If you look at the PDF you see that they have grouped the ages into three categories. Under 18, 18-49 and 50+. It looks like they have calculated the average from just three data points. As the 18-50 group is so big its skews the average towards the middle value of that group 33. A finer division of groups would probably show a greater number of younger people playing games.
