Following up on Dual Boot Failure. I bought a slightly newer ThinkPad at Repowered for about $150. Similar specs: 8GB RAM, 256GB SSD, Windows 10 (but Professional Edition this time). No problems with Windows Configuration. Then I went on to install Xubuntu alongside Windows in a dual-boot arrangement.
‘Nil inti ach gearrchaile,’ arsa Bill agus uafás air.
‘Cailin beag láidir, ionraic, macánta,’ arsa an Duinnineach. ‘Ba chóir go mbeadh náire ar a hathair gur shamhlaigh sé dúnmharú léi.’
‘Fayley could not deny the crime because he feared in his heart that Mary had killed Bella Prunty,’ Dineen said to Bill. ‘On the same subject, he could not ask her any questions for fear of directing attention to her.’
‘She is only a young girl,’ said Bill in horror.
‘A strong, honest, little girl,’ said Dineen. ‘Her father should be ashamed that he dreamed of her committing murder.’

Maybe. See Outing Dietrich Bonhoeffer.
Do I care? No. I still consider him “a Christian hero, a Protestant saint.”
My post Reinstalling Windows concluded with “Right now the laptop is just a Windows system. I suppose I will turn it into a dual-boot system by adding some flavor of Linux, probably Debian or Ubuntu.”
Only harmonic spring and gravity central forces produce periodic motions.
Bertrand’s Theorem. I had to prove this as a homework problem in the fall of 1972, while taking a course in classical mechanics at Stanford. That was very satisfying.
Indian-American mathematician C R Rao awarded Nobel Prize equivalent in Statistics at 102
Rao was already famous among statisticians when I was working for my M.S. in that field back in 1975-76. Nice to see that he is getting the recognition he deserves, and that he is still around to enjoy it.
Elon Musk and other tech leaders call for pause on ‘dangerous race’ to make A.I. as advanced as humans. This has gotten a lot of attention. I found it from a link in TLDR.

I have an old (2011) Lenovo ThinkPad which I used for various tests that I have documented in these pages. At some point the Windows installation on it got corrupted. I tried reinstalling Windows from the recovery drive that I had created, but that failed. So I tried again with a USB drive that I had created using the Windows Media creation tool. I think I had created this on another system, but it worked just fine after I put in old Windows activation code for the system. It took a while to download all the Windows updates it needed, but I expected that.

Why don’t moon photos show stars?. Specifically, why can’t we see the stars in the photographs of the Apollo Astronauts on the moon? As the article clearly explains, all of the pictures were taken during lunar daylight, during which the lunar surface is well illuminated by the sun. This completely washes out the light from the stars. If you made a long enough exposure to catch the stars, the lunar surface, the astronauts and their gear, and the lunar lander would be grossly overexposed. This would defeat the purpose of documenting human activity on the moon.
In fact, this issue was anticipated by Arthur C. Clarke in his classic science fiction novel A Fall of Moondust, first published in 1961, eight years before the first Apollo expedition landed on the moon. Continue reading
‘Nil, a Athair.’
‘Agus cogar, a thaisce, ‘mbionn an clog cruinn de ghnáth?’
D’fhéach Mary ar an gclog, seanchlog a raibh aghaidh bhán bhricneach air.
‘God save us,’ he said, and it was a prayer from his heart. ‘Mary, my heart, There was red yarn to darn a sweater, or the like, which she had on order from the peddler, Do any of you have a red garment?’
‘No, Father.’
‘And whisper, treasure, is the clock accurate as a rule?’
Mary looked at the clock, an old clock with a speckled white face.
