The Holocaust lasted around 4 years, and killed about 6'000'000 Jews.

The Nazi regieme and its civilian and military collaborators industrialised murder, and managed around 1.5 million killed per year.

We rightfully hold those complicit in contempt.



Cars directly kill about 1.6 million a year. Every year, for decades.

Idea

For cached queries, each column has a matching 'page-column', that gives the page is should be on if sorted by that column

That way, we can have a single 'paged' data table, but still correctly sort and page by any column.

e.g. (using sample data below)

To get page 3 when ordering by Type

Once there was a young rat named Arthur, who could never make up his mind. Whenever his friends asked him if he would like to go out with them, he would only answer, "I don't know." He wouldn't say "yes" or "no" either. He would always shirk making a choice.

His aunt Helen said to him, "Now look here. No one is going to care for you if you carry on like this. You have no more mind than a blade of grass."

One rainy day, the rats heard a great noise in the loft. The pine rafters were all rotten, so that the barn was rather unsafe. At last the joists gave way and fell to the ground. The walls shook and all the rats' hair stood on end with fear and horror. "This won't do," said the captain. "I'll send out scouts to search for a new home."

Within five hours the ten scouts came back and said, "We found a stone house where there is room and board for us all. There is a kindly horse named Nelly, a cow, a calf, and a garden with an elm tree." The rats crawled out of their little houses and stood on the floor in a l

Take a normal forth-like

25 4 * 100 =    // true

Add parenthesis as a re-write rule, and move one symbol from the left to the right

write(2 4 *) becomes 2 4 * write
