Ghostly apparitions on Scald Law GM/SS-125

I’ve waited 20 years to capture a brockenspectre on camera and finally I got a selfie with mine 🙂 Full report on all the 2m fun and games to follow.

I gave a talk today (Sunday 12th Oct 2025) at the National Convention of the Radio Society of Great Britain. I was recovering from a horrible virus, so my performance wasn't quite up to my normal standard, and the lighting was a bit weird. Huge fun though. It was great to meet up with folks I haven't seen for many years. I was definitely flagging a bit in the last 15 minutes of the talk! Lots of other great talks in the livestream for today and Saturday 11th Oct

Tony Hawk posted a photo from the 70s of a girl skateboarding in the rain to his Instagram: “New fav mystery skater unlocked.” Jeremy Markovich found tracked down who she was. https://www.ncrabbithole.com/p/tony-hawk-fayetteville-nc-girl-skateboarder-1979
Tony Hawk wanted to track down a mysterious skateboarder from 1979. We found her.

A photographer snapped a shot of Shaunda Shane skating down her street in Fayetteville when she was 10. How did the world's most famous skateboarder see that picture 45 years later?

@AlisonW I have been playing Melt-Banana, Shonen Knife and Three Trapped Tigers at volumes mandating ear defenders. Hope the neighbours like it as much as my dogs like their unpleasant explosives. Dogs are hiding beneath two quilts and a pile of pillows. Least I think that's where they are, it's very easy to mislay two Chihuahuas
@mw1cgg I have a hand nibbler and two power nibblers. The big terrifying one can do 4mm sheet. Also a plasma cutter with radius arms, straight edges and template-following. I can use the Bridgeport or the SYIL CNC, but I have to use tape and superglue to fix the sheet to a mandrel. With a template, the plasma is quite reasonable, but it needs the edges dressing. Mine can do 6 mm aluminium or 12 mm steel

This shader shows the extent of your fovea on your visual field:

"Look at any specific point and you should clearly see the extent of your fovea (the stars only seem to be rotating in a small circle at the center of your vision). Move your head back and forth to see it grow/shrink. Works better in full screen mode."

@schratze @gsuberland then some bell-end tells me to make a h*cking list of fails to reinforce the sense of failure. Great. I've achieved at least 47 important and urgent tasks already today, so IBNUs don't get a look-in. I can't REMEMBER what tasks I've done, but one that I've failed is to complete my timesheet from last week, because I was too busy to remember what I did. Ugh.
@schratze @gsuberland and yet I am sleep-deprived from total overload, don't have a TV, my next Youtube video is two days late, I have dozens of unread and unanswered emails. I'm self-medicating with 10 or more double-espressos a day (which is why I have time to type this)
@schratze @gsuberland To-Do lists are just a visible record of failure. I have IBNUs (Important but not Urgent) items still waiting for attention from 2009. Important like "leaking roof which is damaging the door, walls and ceilings" or "unfinished insulation which is wasting huge amounts form heat loss", or "Parts I promised to make 5 years and two months ago, and still have the items the friend sent me to adapt". Or the tax return that I'm being fined £10 a day for not finishing
