My wife said this represents the two of us, so I think I found the spot for my calculator.

Now we turn the handle counterclockwise to subtract the divisor until we overflow and hear a bell. Then we turn the handle clockwise until we hear the bell again telling us we undid the overflow. We have our answer for the tens place.

Next we move the carriage one position to the left to point to the ones column and subtract until we overflow and hear the bell again, crank the handle clockwise until we undo the overflow and hear the bell, and we have our answer: 12 with a remainder of 1.

Just like multiplication is repeated addition, division is repeated subtraction. First you put the dividend (145) in the accumulator, then zero out the top row which will contain the quotient.

Next you enter the divisor (12) and set the repeat button. Then you move the carriage to right until it points to the leftmost column still greater than the divisor. 14 is greater than 12 so I move the carriage one position to the right to point to the tens place.

Now that I fixed the register on my Monroe LN-160x, the overflow bell works which means I can perform division. Here I am calculating 145 / 12 = 12 remainder 1. The quotient is at the top in red, the remainder is underneath it in black.

Took my Monroe LN-160x apart for a little cleaning and to diagnose the stuck register in the leftmost column causing it to increment by 50000000 with every addition. A few drops of oil and some fidgeting and it loosened up. Now it's working great.

Samsung can remotely brick TVs it believes are stolen once they reconnect to the Internet, which is required to enable smart TV features. ⁨#privacy https://gizmodo.com/samsung-smart-tvs-can-be-remotely-bricked-if-stolen-1847557228

I used this calculator to tally up Scrabble scores this weekend and was pretty happy with how it performed. There is a special kind of satisfaction when winding the crank for each sum.

I (mostly) fixed my mechanical calculator! Here it is calculating 12 x 42. The 8th place from the right increments by 5 with each turn so I still need to take it apart and fix that but otherwise it is working well.

There's a new addition to my mechanical computer collection! This is a Monroe LN-160x mechanical calculator. I didn't notice at the time that it was missing the front lever for the carriage return, and it looks like I'll have to do some repair work to get it working again.

I wrote about the longer-term implications of Apple's client-side scanning, in particular that other vendors will follow Apple's lead and do it poorly.

The hard part is getting customers to accept client-side scanning to begin with. With that out of the way, expanding it later is easy. https://puri.sm/posts/internet-of-snitches/

You should always follow innovations in criminal and student surveillance, because they often serve as proving grounds for tech that ultimately finds its way to the rest of us.

My biggest worry about Apple crossing the Rubicon with client-side searches is all the other vendors that inevitably copy Apple innovations, but poorly. Even if Apple can keep their promises, others won't. Imagine a home (and car) full of devices searching for crimes. ⁨#privacy⁩

Criminals and students always face the bleeding edge of surveillance tech, because neither group has enough agency to resist it. ⁨#privacy⁩ ⁨https://www.reuters.com/article/us-usa-tech-prison-idUSKBN2FA0OO
