This one is pretty hardcore. I bought the 2nd edition of it over 20 years ago when I started my career as a developer due to not doing a CS degree.

It’s not necessarily how far things are, it’s that you need a car to get to places in a sensible way.

I’m a fellow Brit, but have stayed in suburban US enough to have experienced how different it is. You might have a supermarket a couple of miles away, but if you want to attempt to walk there, you’ll often be going well out of your way trying to find safe crossing points or even roads with paved sidewalks.

Train stations are mostly used for cargo in most US cities. If you don’t have a car, you’re pretty much screwed.

Some cities are different. NYC being the obvious one. You can get about there by public transport pretty easily in most places there. San Francisco is another city that is more doable without a car, but more difficult than NYC.

I stayed near Orlando not too long ago and there it’s just endless surburban housing with shops and malls dotted about mostly along the sides of main roads. You definitely need a car there.

Also take a look at the Specification Pattern for something similar.

That’s something I would only use if the logic becomes very complex, but it can help break things down nicely in those cases.

Why the assumption that reactivity is only a front-end thing?

I’ve used it plenty on the back-end when dealing with streams of data that need to trigger other processing steps.

Maybe let’s just say that you and I have different senses of humour and leave it at that.

For me, the humour comes from the fact that I pretended not to understand the image and point out that there are no plugs in the image. It’s a bit of wordplay that relies on the fact that people sometimes call plug sockets plugs.

I’m from the UK.

It was a joke. Don’t take things so seriously

Sure, there’s a lot of plug sockets there, but I don’t see a single plug in that image

Same, using Chat GPT 4. It explained the steps without prompting, which is different from the single line answer shown in the post too. I got this…

Let’s break this down step by step:

1. Sally has 3 brothers.
2. Each of those brothers has 2 sisters.

Sally is one of those sisters for each of her 3 brothers. Therefore, the second sister that each brother has would be the same other sister.

This means that Sally has only 1 other sister, making a total of 2 sisters in the family (including Sally herself).

So, Sally has 1 sister.
