Undefined behavior can go bad quickly.

Could go the other way though. Ask them nicely if they'd be willing to free up their heap of inventory, and if they return you a cart overflow, you know you've stumbled upon the ultimate zero day coupon.

I give money to cashier, change comes out of coin dispenser. I say "Looks like I won again!", cashier dies a little inside.

Every time.

Long long ago in a callcenter not too far away, I made a guy choke on his drink. As required, I asked if there was anything else he needed before I ended the call, to which he replied "the winning lottery numbers?" I said "if I had those, I wouldn't be talking to you."

No, but these nulls might indicate references that previously pointed to memory that was freed.

I worked in groceries story when I was younger.

But funily enough, it's probably one of the rare times I'd have answered "yes"!

We got a policy here where anything mislabelled under 10$ is free for the first item. Anything over 10$ gets a 10$ rebate.

My understanding is that it was put in place a while ago when stores stopped labelling individual items to keep them in check and ensure that consumers had a recourse in case of mistake.

NULL being "no money" by any definition, and the regular price for this probably being under 10$... well, it's probably free!

Everything is free. The problem is avoiding the cops afterwards.

How about

Class lol : Object
{
public static init void main (string args)
{
    virtual void A_Start()
    {
          Java.Print(args)
          break
     }
}
}

In case it's not clear, I know nothing about Java.

It is funny, it’s just that the amount of funny is null.

[–] matti@lemmy.world 11 points 3 years ago (1 child)

When you buy these an exception is thrown.

[–] Speiser0@feddit.de 1 point 3 years ago

Real world doesn't make exceptions. So you'll get UB.

Item labels only do this when they're very stressed

[–] andthenthreemore@startrek.website 6 points 3 years ago (4 children)

Programming aside electric self edge labels are the future. Where I work we do paper labels for about 50 pretty small stores and use best part of 30,000 sheets of paper a week.

I imagine with inflation causing an increased frequency of relabeling and relabeling costs causing an increased rate of inflation, it's only a matter of time before I become too lazy to finish this joke.

600 labels per store per week. Seems like a big chunk of the inventory changes price every week, not just some tens of articles for a temporary sale.

parent

[–] andthenthreemore@startrek.website 2 points 3 years ago

It's more. Each a4 sheet has considerably more than 1 label on it. Most weeks there's 90-100 pages of weekly limited offer specials alone. Then every day there's large amounts of regular stock coming onto and off of special offer. Then produce is constantly being adjusted based on seasonality, the current weather (better prices on salad when it's hot etc), and to help sell through (warehouse has accepted some stock with reduced shelf life etc).

Then there's the fact the country I'm from has been experiencing food price inflation at almost 20% this year.

Yep. My work is rolling them out later in the year. The ones we are getting are basic colour eink, I think they can do a little red to highlight special offers. Batteries are supposed to last several years.

Free olives, the cost is listed as 0.

Don't try to buy it unless u want the register to open a black hole when the cashier puts it in.

Isn't NULL a macro in C for 0? So doesn't that mean these items are free?

[–] coloredgrayscale@programming.dev 2 points 3 years ago

In a way it's still the same with more modern languages. Especially OOP, setting an object to Null is just setting the address pointer to to 0x00000000.

Hence NullPointerException / NullReferenceException or similar, depending on the language.

I'd guess, in context, it's a floating point price column that hasn't been set, and the table designer didn't specify the column to be NOT NULL.
