How to Use Ternary and Null Coalesce

? : for if-else. ?? for null fallback. ??= for assign if null.

Ternary Associativity

PHP ternary operator is left-associative! This trap catches everyone. Can you predict the output?

One nice thing about (standard balanced) #ternary #logic is that: if we use −1 for ⊥, 1 for ⊤, and 0 for the third value, then p∧q ⇔ min(p,q), p∨q ⇔ max(p,q) and ¬p ⇔ -1*sgn(p)

OK, maybe I went too nerdy 🤓 on this one? 🤣

#Ternary

Middle aged whit man looking at the camera. He is wearing a green T-shirt that has the following written on it:

There are 10 types of people: those who understand ternary, those who thought this was binary and those wondering, what the fuck!?

Now when I see 2012 I realise that the hour is about to change. I'm learning! 😉

#Ternary

Watch with time encoded in base-three. The minutes show 2012, which is 59 in decimal.

For those of you in Europe that just had #DST end, I hope you remembered to update your clocks and watches. My watch already updated itself correctly, as you can see. 😉

#ClockChange #TimeChange #Ternary #Time #WristCheck #Wintertime

A Garmin Venu 3 watch with a watch face that shows the current time encoded in ternary, with colourful digits:

022:1201 = 08:46

As fun as the previous face was, I decided I wanted a bit more information displayed.

So I switched to this alternate ternary dial (also made by my friend).

The colours are all customisable. I have the minutes in a different colour to the hour so that I can locate them quickly at a glance, as I tend to decode them first (given I usually know the hour already).

This face can also show a step count but that is way too much effort to decode right now! 🤣

#WristCheck #Ternary

A watch dial on a Garmin Venu 3 with the information encoded in ternary using digits in a range of colours.

02020 = 60%
101 = 10 (Oct)
0221 = 25th Day
110 = 12 Hours
1000 = 27 Minutes
1012 = 32 Seconds

Morning all. Looks like it is time to wake up.

#WristCheck #Ternary

A smart watch which encodes the time in base-three via the state of teeth on a weird looking face. Upper row of three are hours and lower row of four teeth are minutes. The date of the month is in base-six via the eyebrows. The eyes show the seconds.

07:00:43 24th

Had I waited any longer I could have potentially been SOL. #nonbinary #protest #uspol #ternary #transrights #tech #uspolitics #gender #lgbt #lgbtq #axab #passport #intersex #protecttranslives

#setun #ternary

NOT Binary code of 1 or 0, Control Unit coded to like ternary 012, Quaternary Coding 0123, etc😜

If you have time to waste🤷‍♀️, there's so much more nonsense here👇

Quanta Magazine writer, Stephen Ornes makes a case for ternary computing in 2024, surveying recent efforts to revive tri-state systems, and their advantages over their binary counterparts in certain types of computation.

#computing #ternary #hardware

I'm looking to sort of recreate the #setun or #setun70 processors for fun. They are Soviet computers created during the cold war. Soviet computing in that era is interesting caused they kinda had to create their own alternatives because of social isolation. While everyone when the tube route they created computers out of coil and ferrite cores. Since ferrite can be magnetised in multiple directions they created computers that works with 3 states. 0, 1 and T. Those units where not bits but trits. It's not binary but #ternary. Of course, that changes all the logic. According to my researches at the moment, it seems like memory reading was destructive so memory needed to be rewritten every single time. It's just an other world.
