What if you use prescription lenses?

I use "Note Everything" on my Android phone. I found is uses a SQLite db for storing its info. Might try this for extracting the contents if I ever want to move to Apple phone.

Just tried it. I have Note Everything save to Google Drive. Extracted that zip file, read it here, saved the text notes as csv, looked at it in txtedit. Great!!!!

Could write a gawk program to recreate the notes in directories.

I have an M1 Max MBP (16", 64GB, 4TB) and I see no need to upgrade. I got it when the M3 came out so I saved about $2,000.

And then you have the Trump administration's war on competence.

The Reason Foundation has a series of Youtube videos about things that were done with good intentions but ended up making things worse.

So glad I am retired.

For some reason I read this as

Making Referential Stupidity a Type

For math.stackexchange.com which uses MathJax, I use MacDown, a markdown editor with parallel windows, one showing the MathJax and the other (in real time) the rendered math. I find it essential.

I enter my math directly into the editor without writing anything on paper. Works for me. The ability to copy and paste is invaluable.

The ternary operator is easy to nest if you put each clause on a separate line. Then it looks just like nested if-then-else.

Years ago, I used Acrobat to extract tables from a PDF. Had to do it manually, but it pasted nicely into Excel.

As usual, anything Trump and his minions touch turns to garbage.

I believe that I got the first external cassette drive for the PET on the west coast. Only used it a very few times. The big boost was when I got the floppy disk drive. I could do anything!

For a nice introduction to relativity, look at The Einstein Theory of Relativity: A Trip to the Fourth Dimension by Lillian R. Lieber. $15 on Amazon. Written in 1945 and still quite good.

I enjoyed this article. I always find it interesting how things came to be and how individual contributions made things happen.
