@dredmorbius Summary is:

1. MS (and AD) strongly contributed to and enabled a culture of bad passwords. While they didn't invent bad password policy, their defaults and recs became gospel to many IT admin and AD enabled bad policy to scale, training a generation of computer users to make bad passwords.

2. "Passwordless future" enables vendor control of hardware, as auth is strongly tied to hardware security, which is anchored in trusted (signed by MS) software.

I didn't realize just how much I blamed Microsoft for the current state of passwords until I sat down to write about their "passwordless future": https://puri.sm/posts/microsoft-ruined-passwords-now-aims-for-a-passwordless-future/

More than 26,000 PG&E customers were without power in the Bay Area today because of fog and mist. Fog. and mist. https://www.nbcbayarea.com/news/local/over-28000-customers-experiencing-power-outages-due-to-fog-mist-pge/2660562/

This is the carry mechanism for the Monroe. The bars form a wave and the last few move, but were completely seized up. A few hours with some oil, pliers, a screwdriver, and ultimately a heat gun, and it finally loosened up. Subtraction finally underflows all the way to the left!

Yesterday I spent a few hours restoring this Monroe Model G calculator. It was only after putting everything back together that I discovered the accumulator is only underflowing half the digits when doing subtraction/division, so I get to take it apart again today and fix that.

@twrightsman I'm using native apps in this case.

@KekunPlazas @tbernard This is one big reason why I've been experimenting so much on the side with running browsers inside bwrap so I could have a persistent but externally-sandboxed browser for more trusted browsing, and a disposable sandboxed browser that erased its sandbox when the window closed, for untrusted browsing (like opening URLs from external sources).

The implementation is pretty simple, it's just a matter of maintaining bwrap rules long-term.

To elaborate, this is a disposable VM just for opening random, possibly untrusted links other people send me. I do most of my own browsing in a different VM with ad and javascript blocking in place. It's always jarring to see just how bad the web is without all of that in place.

How do regular folks stand browsing the modern web? I have a VM for opening random links with no javascript or ad blocking. When I open certain news sites my laptop fans spin 100% loading all the ads, and it's almost impossible to read the actual story.

@RyuKurisu I believe modern CPUs have a lot of different sets of instructions, but my understanding, if we go back to early binary computers, is that they implemented Boolean logic (AND/OR/NOT and their combinations), from which you can derive things like addition operations.

People subtracted on adding machines w/ a neat trick: the complements method. Convert a number to its complement, add it, and discard the extra "1" on the left. Many calculators with subtraction functions use this method under the hood: https://www.mathsisfun.com/numbers/subtraction-by-addition.html

Of course if you can add repeatedly you can multiply, so this machine has a "repeat" button in the bottom right corner. Once pressed, any number you enter stays pressed down after you pull the addition lever, so you can add over and over just by pulling the lever.

The Burroughs is a true adding machine--it can only *add* numbers. Notice the limited buttons on the keyboard. If you ever heard someone refer to a modern calculator as an "adding machine" it derives from the fact that originally that's all they could do back in 1908.

This adding machine has a carriage at the back so you can add a paper spool or even a sheet of typing or ledger paper, with tab stops you can set to speed the process of filling out forms.

This is my Burroughs Class 1, Model 7 Adder/Lister made in 1908. The glass sides and front let you watch the mechanisms as it's adding.

These antique calculators have a funny way of multiplying...

There is something special about the first phase of a new hobby. So much to learn, new skills to master, deep rabbit holes full of discoveries around every corner.
