So, using up to 5 coins (1p, 2p, 5p, 10p, 20p and 50p) first she asked our kids whether they could make every value up to 50p, and then what the smallest value they couldn’t make was.

What lens should I buy next ?; Analysing and graphing a Digikam database using R
I use the Open Source photo management Software Digikam (along with other tools such as Gimp and DarkTable). I obviously need very little encouragement to combine my geeky hobbies, so I quickly tried to interrogate Digikam with R, which is easy, because Digikam keeps all it’s image info in a SQLite database, which R has support for. So this p...
