I decided to plot the curve of solutions: https://www.desmos.com/calculator/mct44zkpjh
I got 108 problems but a warning ain't one.
How did I not know this? The decimal expansion of 2017 repeats every 2016 digits!
Now I wonder if these batch numbers are in binary
Saw this lovely, if slightly knacked, adding machine in the Sun Inn, in Morpeth. You stick a stylus (or a finger) in one of the holes and drag it down to add to a column. It was a bit rusty and skipped digits more often than not.

oh wow, gvim renders emoji!
I'm on holiday in the Hague. Here are some of the things I've seen
Spotted this nifty Cairo tiling on my hotel room wall in Den Haag
Intriguing! A brick that's like the 3D analogue of A-series paper: you can cut it in half to produce two bricks similar to the original
Mrs L-P had a very happy accident at the photo printers
You know how something can be 'over-engineered'? Well, I think some things are over-mathematicianed.
This bouncy ball, on sale for a couple of quid next to the tills at Mothercare, is a fine example. It's made of six rubber threads, woven together to make a shape with dodecahedral symmetry, such that each face has five different colours. Why six threads? So it can embody the outer automorphism group of \(S_6\)!
It was invented by Dick Esterle. This is my daughter's one; my dog has a bigger one.
I've been told there are colours in this tree.
Recently I discovered a surprising fact about numbers, so I made an online web thing to give it the recognition it deserves. Give it a go: http://somethingorotherwhatever.com/sum-of-3-palindromes/

I really love capturing the state of a highly viscous fluid at a snapshot in time, AKA baking a marble cake 🎂 😛
This output is quite aesthetically interesting.
Ha! Totally buying this Zermelo Fried Chicken t-shirt
I've been enjoying playing Rikudo Puzzles on android - https://play.google.com/store/apps/details?id=com.rikudo.numbers
It's like Simon Tatham's Signpost game, but on a hexagonal grid. You have to place numbers in the cells to form a contiguous path which fills the entire board. I don't get much out of the timer and stars for finishing quickly - I just like solving the puzzle. Placing numbers can be a bit fiddly - it's very easy to accidentally switch to counting backwards, or miss out a number.
