307. THE COLOURED COUNTERS. The diagram represents twenty-five coloured counters, Red, Blue, Yellow,
Orange, and Green (indicated by their initials), and there are five of each colour, numbered 1, 2, 3, 4, and 5. The problem is so to place them in a square that neither colour nor number shall be found repeated in any one of the five rows, five columns, and two diagonals. Can you so rearrange them?

So we always go to the doggy park around sunset - there are loads of huge trees there and the sun is always twinkling through them with lovely Golden Hour light so I figured tonight I'd try for some sunbursts - you need a high F-Stop but compensated with slow shutter speed and/or high ISO, and careful positioning, and it can be tricky.
So I'm fracking stoked that I got this DOUBLE SUNBURST. AAAAH

Another sobering talk from Maciej Ceglowski. He's shaping up to be a good candidate for "conscience of the tech industry."
Prompted by a stupid tweet by QI on twitter ("If the 5 trillion spiders in the Netherlands took to eating humans rather than insects, they’d consume all Dutch people in just three days." - https://twitter.com/qikipedia/status/950894962559897600), I reckon that it'd take the UK's window cleaners 2.5 months to cover the distance to the moon if they did that instead of climbing ladders
