DerekL··on Deceptive example for malicious usage of .zip domain
How exactly does this trick work? Thing is, a URL can't have any non-ASCII characters in it. So this would only happen if the webpage or some app takes the URL and undoes the percent-encoding to try to make it more readable.

DerekL··on Pro-cash movement warns that people could be losing more than they bargained for
I can imagine this scenario:

Cashier: Your total comes to $8.45.

Customer: All I have is a $20. Is that okay?

Cashier: Yes, it’s San Francisco law that we accept cash.

Customer: Okay, here.

Customer: …

Customer: Where’s my change?

Cashier: We accept cash, we don’t give change.

The San Francisco law doesn’t require that change be given. Be prepared to carry small bills and coins.

Do you mean “Ada”, the programming language? It's not an acronym.

DerekL··on Legend of Zelda game sells 10M copies in three days
I'm not sure if that's correct. While Nintendo does make some profit selling the Switch console, it's not much, and they make most of their money by selling their own games and charging fees to third-party developers. But I don't know the exact amounts, so this may be wrong.

But if you're in Python, why would you need to need to execute separate processes to do any of that?

The SNES wasn't at all underpowered compared to the SEGA Mega Drive. In fact, it was better in many ways.

I think you mean steganography.
DerekL··on Lotus 1-2-3
Others have mentioned the ways that DOS was good enough or even better for some applications. One of the main strengths of a GUI wasn't being graphical, it was that every program had a similar interface. If your work just uses one program, DOS wasn't bad.

But remember that the people who use computers aren't the people buying those computers. They're purchased by the boss, and the boss isn't going to spend a single dollar for a better user experience, much less the hundreds or thousands it would have cost. This still applies today to enterprise software.

DerekL··on A Programmer's Introduction to Mathematics
Can't you define a discontinuous function over some other set besides the reals, such as the set of all computable numbers? For instance, a step function is discontinuous at a single point. You can also define a function that's discontinuous at every point, such as the indicator function of the rationals.

I don't have any experience with constructive set theory, so maybe I'm missing something.

DerekL··on SNOBOL (“StriNg Oriented and SymBOlic Language”)
I don't think so. As far as I know, ZIL was a variant of Lisp.

Great! That was really bugging me.

DerekL··on Atari 800XL Remake
Years ago, I ported the emulator Atari800 to Macintosh. I used MULE's title screen to test the sound emulation.

Who knows, but Ukrainians really need to not live under Russian rule, because the Russians will steal their toilets, steal their children, and beat them for speaking their language.

The Apple II supported programming and hardware development, but mostly it was used with pre-made software like VisiCalc.

DerekL··on Ask HN: Why don't smartphones encourage programming like early 80s computers?
Many Android developers now use Kotlin instead of Java.

They're on iOS too.

DerekL··on Ask HN: Why don't smartphones encourage programming like early 80s computers?
But even then, most of the time computers were used to run programs written by others, such as spreadsheets, word processors, and games. (Though a spreadsheet can be thought of as a specialized type of program.)
DerekL··on Why does a plastic-wrapped turkey sandwich cost $15 at the NYC airport?
This is just false. Even forgetting about all of the overhead of making sandwiches, it's more than just a dollar's worth of ingredients. The skimpiest sandwich will probably have more than 2 ounces of meat, more like 3 or 4 ounces. The cheapest turkey from the supermarket is about $0.50 per ounce. So that's more than a dollar right there.
DerekL··on Why does a plastic-wrapped turkey sandwich cost $15 at the NYC airport?
The title is incorrect. As the article states, there is more than one airport for New York City, so the phrase “the NYC airport” is misleading.
DerekL··on Why does a plastic-wrapped turkey sandwich cost $15 at the NYC airport?
No, it is not owned by the City of New York. It's owned by the Port Authority of New York and New Jersey, which is controlled by those two states.
