I read WordTsar Is Reviving the ’80s WordPerfect Writing Experience with considerable interest, but following it up with a look at WordTsar and WordTsar: Wordstar for the 21st Century quickly showed that the first author was not present during the word processor wars of the 1980s. WordStar lost to WordPerfect in that conflict, but still has some diehard fans, the most famous being George R.R. Martin, who still uses it on a DOS machiue. I have been able to run WordStar on FreeDOS, with FreeDOS running on a virtual machine. This was WordStar 4.0, which is now “abandonware,” i.e. free, but without any official support.

Another look at the “Flat Earth” Myth
As I wrote in Columbus and the Flat Earth: “No educated European in 1492 believed that the Earth was flat. They all knew it was round.”
A recent Twitter thread (Original tweets here) covers much of the same ground, with the same conclusions, but with a current example:
First steps with LaTeX
Working through Create Beautiful Documents (better than Word) using TexStudio on Ubuntu Linux.

More about the new(er) ThinkPad
The 256GB drive on Another ThinkPad seemed a little small, so I replaced with 1 TB SSD. As in previous moves, I used Macrium under Windows to copy the contents of the existing drive to the new one, then rebooted into Linux and used gparted to add a new NTFS partition and a new ext4 partition on the larger drive. Following Lenovo ThinkPad X240 – Hard Disk Drive Replacement I physically removed the old SSD and installed the new one. Afterwards I rebooted into Windows and the new NTFS partition showed up as the D drive as planned.
Another ThinkPad
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.

Dineen in Duckford (continued)
- Ní fhéadfadh Fayler an choir a shéanadh mar bhí eagla air [d.l. 179]
ina chroí istigh gur mharaigh Mary Bella Prunty,’ arsa an Duinnineach le Bill. ‘Ar an ábhar céanna, níorbh fhéidir leis aon cheist a chur ina taobh ar eagla go ndíreodh sé aird uirthi.’‘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.’

Was Dietrich Bonhoeffer gay?
Maybe. See Outing Dietrich Bonhoeffer.
Do I care? No. I still consider him “a Christian hero, a Protestant saint.”
Dual Boot Failure
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.”
A note on central forces
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.
Calyampudi Radhakrishna Rao
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.
