Will No One Rid Me of This Troublous University?

Okay, I am mixing periods.  9/12/24 Daily Mail:
"Woke row erupts after Nottingham University puts trigger warning on Geoffrey Chaucer's The Canterbury Tales - because they contain 'expressions of Christian faith'"

Horrifying.  Are there trigger warnings on History of the Holocaust classes?  Probably not.

Today's Obscure Windows Question

 My laptop came with a 1TB SSD.  Within a year or two, that was not enough.  (I have more PDFs of antique American statute books than you can imagine.)  I did not want to risk fauilure to copy over from my old drive C to my new drive, so I made my new drive D and told the BIOS to boot from the new drive.  

Now, I have drive C with 160GB free, and drive D with all my files and programs installed on it.  I would like to be able to clear drive C and map various directories (Pictures, Documents, Videos, Downloads) to drive C.  Perhaps map all the non-programs to drive C.

In Linux, assuming that my memory of how symbolic links work is correct, you would create a symbolic link so that D:\Users\clayt\Documents actually points to C:\Documents so all references will actually turn into C:\Documents.  

It appeears that a directory junction ("mklink /J link destinationfolder") does what is required.

I created a junction link 

mklink /j "D:\users\clayt\testlink" C:\testlink

Then I copied files into D:\Users\clayt\testlink.  They appeared in C:\testlink.  If I deleted a file in D:\Users\clayt\testlink, it disappeared in C:\testlink.

I Was Actually Well Enough to Do Astrophotography a Few Nights Ago

Of course, once I was outside, I realized the two AAA batteries that power the clock drive were dead.  (The power switch is in a position that makes it easy to forget to turn it off.)  Nonetheless, short exposures (1/80th sec. ISO 800) still produce okay images.


Video is required to produce higher quality images and you can see the tracking issue and general atmospheric instability:


Adding to the fun is that my fast laptop (128GB RAM) cannot read the camera's SDXC memory cards through a USB adapter,  The travel laptop pretty obviously does.

Star Trek: The Original Series

 I am part-way through season 1.  I do not mean that all humanoid species seem to be just like us, speaking and understanding English, or that many alien worlds have an uncanny similarity to Southern California.  There were sound reasons why a 1960s TV series had to operate within these artificial and unrealistic constraints.

The stories could be amusing, such as "Shore Leave":  "Oh my, whiskers," followed by Alice chasing after the rabbit.  "Arena" was another favorite.  When I watched it for the first time, when he got to the saltpeter, I knew immediately where it was going.  It has a very positive ending to a very dark story.  

Where Star Trek really shone was its connection to the great events and concerns of the time, some of which remain today: "A Taste of Arnmageddon": How do we confront the hazards of Mutual Assured Destruction?  While I do not remember the title, the one with the Salt Vampire:



was a powerful commentary on the loss of magnificient species such as the American bison.

Some of the stories were destroyed by silly costume ideas.  "The Return of the Archons" is set in a situatuion where not only do the humanoids speak English but they are dressed and living in a late 19th century Midwestern town, with no explanation for this weird mixture of aliens controlled by a computer obsessed with peace above creativity with a very specific Earth setting.

"The Cage" was an impressive repurposing of footage from the pilot "The Menagerie" to produce two episodes on short order.

Pistol Prices in the Early Republic

 Framing Era and Early Republic Pistol Prices

Finding prices for pistols in this era is a struggle.  Advertisements do not generally list prices for much of anything.  Until the advent of the Quaker “one price” system, purchases involved haggling and the proprietor’s perception of what a buyer could afford.[1]  However, we do have U.S. Government contract information telling us they were willing to pay for military pistols.

We can also convert these prices into hours of labor for agricultural workers for each contract year.  All pistol contract prices are from Carl P. Russell Guns on the Early Frontiers: From Colonial Times to the Years of the Western Fur Trade.[2] Agricultural daily wages are from Carol D. Wright, Comparative Wages, Prices, and Cost of Living, 46-47.  When there are multiple wage levels for agricultural workers, I am using the lowest wages for that year, which will exaggerate how many days a worker would need to buy a pistol.

No, Not the Babylon Bee

 3/11/24 Daily Telegraph

"Pink-haired DEI trainer slams Oregon forestry bosses 'for hiring on basis of merit not gender or identity'"

Obviously, the pink-haired, face tatooed DEI trainer was not hired on merit.

Remember the 1950s Space Films Where a Rocket Lands Tail First?

In retrospect,  these were absurdly impossible.   Watching the video in this 10/13/24 BBC coverage of Starship booster landing in a scissor-lock is just amazing. 

Elon Musk really is Ironman.
