Scam call from 07351340054 talking about a fundraising project and printing books for schools that. Then trying to get me to agree to an invoice for £219. I strung them along for a while before telling them it was impossible to agree to anything before checking with whoever authorised it in the first place. They instantly hung up.

Take the parity of the indices of the terms of the continued fraction of Liouville's constant that equal 8. For odd numbers turn left, for even turn right.

What do you get?

The Dragon curve appears, again. It's everywhere.

This works with indices equalling 1 too (for 9 you'll have to ignore the first digit)

Philips Ultra Efficient LED bulbs output 210 lumens per watt but have a power factor of 0.4

That's not great.

chatgpt.com is down and people are raging that they can't get their work done. Maybe they could, like, do their own work themselves.

I'll visit somewhere else. Enshittified cashless is even worse than normal discriminatory cashless.

Going from the dragon curve to that sequence is slightly more tricky but only involves counting the number of times a turn is flipped left/right or right/left at each iteration.

Fiddling around with some recursion and the dragon curve and what should pop out but this exact sequence.

https://oeis.org/A072339

While it wasn't at all obvious to me that it would match a sequence like this, it is easy to demonstrate the connection. Take the odd numbers and use them as right turns and the even numbers as left turns.

Shame I don't have access to Knuth's work to see if the connection is described there.

After repairing a Drayton SCR (X2 cap), a Honeywell CM927 (new 72 way, 0.8mm pitch, flat wire conductive adhesive nonsense), and starting a repair on an Ideal V9 PCB (3 output transformer removed), it was time for some sparks on the workbench.

Cheap chinese bifilar Tesla coil,(bluetooth version for square wave musical earache if that's your thing).

What would you expect 'natural vanillin' to be?

1. Vanillin extracted from vanilla pods.

2. The above and/or vanillin extracted from other plant sources.

3. Ferulic acid produced by the hydrolysis of γ-oryzanol found in rice bran oil soapstock, fermented with other chemicals in a bioreactor, then purified.

There is absolutely no way this lighting circuit passed insulation testing when the fuseboard was replaced 4 years ago. There's been a screw through this cable for at least 15 years. No wonder they had random nuisance tripping. Amazingly the RCBO held most of the time.
