So it's only about code coupling?

What if it's an app that no one is able to see its code, why would encapsulate matter?

>why would it matter if the user won't be able to see the code itself?

If you can see the code itself, you can derive flaws from it. If it's backend code... now you are subject to a whole host of attacks, because people know the names of your tables. People can utilise specific endpoints and pick flaws in your code.

If it's FE code it's not quite as bad but nonetheless you can still figure out flaws and tailor attacks/exploits based on the code you are looking at

As the code base grows it will be exceedingly difficult to maintain, and eventually any change in it will result in bugs fixing which will be far more difficult than adding features.

I’m not sure if they still have restrictions but in case anyone didn’t know it did used to be restricted. I got my membership because my parents had one. They got one because my dad worked for the county. You could also qualify if you owned a business or worked for a business that had a membership. There used to be some hoops to jump through that were always pretty easy to jump through. Possibly to make it seem even more exclusive. I don’t know if they still do that though.

u/MikeTorsson, can you clarify your question? Restrict in what way? Everyone commenting here assumes you mean that because they charge a membership fee, Costco is restricting membership to those who can afford that. Is that what you mean?

Hope they sent you via bus to Florida and dropped you off outside the Governor's house there.

I'm not going to lie, I am a complete Costco mark, ha.

> You pay the money, you get the membership. They don’t restrict it to certain people.

You say that but you take one shit — ok ok — two shits in the rotisserie chicken station and all of a sudden you’re “no longer welcome at Costco” and “under arrest” and “deported from Canada.”

You can play with any number of people (two is enough, even one person with a wall)

You can play anywhere (street, field, car park, small garden, beach)

You can play with zero equipment (tin can, any ball, school children often play with tennis balls, anything you can kick).

Thanks

Batteries store chemical energy and convert it to electrical energy. the chemical reactions that happen involve the movement of electrons which creates an electric current

chemical reactions are atoms exchanging electrons, all a battery does is force the atoms to exchange electrons through a wire

I am not suggesting that kids get their own boat and boathouse. I have lots of fun memories of borrowing the boat of by parents or even the neighbors boat which they have to go fishing, transport things across the lake and through the canal, etc. in order to race with my friends at the time.

>Fields, as in scientific fields? Are there any that still commonly use imperial units at all?

More industrial fields, but it's still pretty common in engineering R&D in fields where the academic, scientific, and industrial lines get blurred.

Automotive and Aerospace engineering, for example.

>Are there any that still commonly use imperial units at all?

Aerospace is still overwhelmingly Imperial, at least until you get to space. Altitudes are measured in feet, speed in knots, thrust and payload in pounds, power in horsepower (particularly for piston-cylinder engined aircraft).

There could be a psychological element to it.

Some people might say to themselves "if I am going to buy a membership, I better use it." As result, they buy more stuff at Costco than they would at a normal store.

So yeah, Costco certainly has fewer customers, but the customers they do have are more likely to spend more money.

They only restrict it to all people who are willing to pay $60/yr...

Basically, their entire business model is effectively selling goods at cost and making their profits from the membership fees.

Are there people who don't shop there because they don't want to pay the fee? Sure... but those who do pay the fee are more brand loyal and shop there more. There are efficiencies from selling more stuff to fewer people than trying to serve more people.

Costco's entire business model is based off of making money off of selling memberships. Their margins on selling stuff is extremely low.

This explains it.
