Seriously. I enjoy actually tasting things that aren't ketchup. I like putting, brown mustard, onion, relish, tomato, sport peppers, celery salt, and sometimes sauerkraut on my hotchardogs/sausages. Good thing I'm around Chicago, where if you ask for ketchup you will be ejected from the premises.

Gotta say I didn't get it, and it's been a while since there's been one of those. ._. Thanks for the people who linked to the wiki article, though. Always good to learn new things. (Getting more out of xkcd than I am out of the calculus assignment I ought to be doing right now.)

...So what do you call the stuff you put on spaghetti? Because that's what tomato sauce means to us, and the reason we borrowed ketchup to refer to the condiment.

Ketchup doesn't belong anywhere near hotdog.


Wait, you don't put tomato slices /wedges, peppers, and pickle spears ON the hot dog, do you? There's barely enough room for the other stuff. And ketchup is just there as a base flavor, don't get all high and mighty about it.

But then, I haven't had a hot dog in years, ever since I was old enough to understand that they are made basically from all the stuff not good enough for all the other meats, and only have sausages I know to not be made that way.

Shouldn't the mustard have been next to the sausage? Looks like a weird postfix & infix mix!

Thank you fora for explaining this joke to me, and making me learn something.

In other news, Polish sausage tastes really darn good.

I was so lost with the joke, I first thought it was an Alan Kulwicki (via Polish Victory Lap) reference. I was almost compelled to come out here to say it... when I remembered that damn reverse troubles with a friend's HP 48G. God bless Texas Instruments and their TI89 Titanium. God bless them, undoubtely.

Didn't get it until I read the forum posts. Clever, clever...xkcd's always there to point out "ha! there is math stuff you don't know! glory is mine, n00b" in place of someone else that did the same a few years back. I liked the coloring even more though.

I'm thinking about RPN all the freaking time, so I "got" this right away, but I'm still not sure how the joke works.
I guess the hot dog is the operator, and the buns are the operands?

Also, I can't believe my parent paid like $200 for a TI-89 Titanium and it won't even try RPN. To re-iterate some posts I've already made, graphing calculators are a colossal scam, and a monopoly.

Definitely a monopoly. The Faculty of Engineering at my university only certifies specific calculators (we have to get them stickered) for us to be able to use in tests, and they're all Texas Instruments. Then again, I've never used RPN, though it doesn't look like I'd particularly enjoy it.

Indeed; the operation goes thus:

Code: Select all

bun_left bun_right APPLY_SAUSAGE

At least, that's my reading of it.

I registered and logged in only to say that this comic was extremely unfunny (I understand it, but it's NOT funny).

Also, I'm pretty damn sure that L.O.L is what filters to the cheese is burning me or whatever.

Am I the only person here for whom RPS already has a well-defined, internet-specific meaning? I guess I spend too much time on fanfic sites...

I'm afraid a sausage seemed rather bland compared with the theme I was expecting.

Very funny. In my opinion larger stacks of foodstuffs are needed though: tomato, lettuce, sauce, onion, whatever (maybe make it a burger instead of a hot dog). You can make a nice mess of them. Like I usually do in 'dc' when I let my stack grow too large.

I got this only because my dad is an engineer, and tried to convince me to use an RPN-capable scientific calculator instead of a "conventional" scientific calculator on a few occasions in high school.

Mine has the teal and lilac superscripts though, unlike the classic orange and blue, which I hated as a child, but now feel nostalgic for. Any other UIL calculator veterans on the forums?

Bun Sausage + Mustard +. Yep, needs more postfixin's.

I suggest Bun Knife / Butter + Sausage + Mustard + Fried Onions + Pickle 2 * + Coleslaw + Ketchup + 2 *

Finally a truly awesome comic again! I sniggered heartily at this. Can't understand how people can find this not funny (at least if they get the joke). I also appreciate that this comic is more in the "true" XKCD spirit again than most of the recent ones.

No truer words have been spoken.

You don't learn RPN, you unlearn infix. RPN is the natural language of your brain. Once you experience RPN enlightenment, you seriously wonder why anyone would even consider using an infix system.

The glorious thing about the 48G, which made it more then just a graphing calculator, was the stack. We need to petition HP to bring it back. My 48GX is still going strong, but have nightmares about it getting lost or broken.

And here I came to make mention of how much colour was used in the comic, whereas we've mostly been seeing stick figures, it's a nice arc back to the more classic comics of yesteryear *getofmylawnhttp://www.youdamnkid.com/d/19990301.html* :evil:

One of the fun way to debunk claims about rationality in The Market is that a number of usability studies have shown that nearly everybody (except the occasional math wiz) can use RPN calculators more easily than the infix kind. But almost all commercially available calculators use infix notation. This is just one of many examples showing that the commercial world isn't concerned with usability.

This has led to at least one loss of mathematical understanding. Try asking people what the value of 2+2*2 is, and you'll see it. At least here in the US, nearly everyone now answers 8, and you can find it difficult to explain why the correct answer is 6. Very often, people will "prove" that you're wrong by picking up a calculator, typing "2+2*2=", and showing that the answer is 8. The calculator can't be wrong; it must be mathematics that's wrong.

One thing I like about that "proof by calculator" is that you type the '=' at the end, which looks very much like an RPN operator. If it were infix, you'd expect the calculator to wait until you type the result, and then it would show a T or F, depending on whether you typed the correct result. So "infix" calculators not only fail to calculate correctly by ignoring operator precedence; they actually implement a mixture of infix and RPN notation.

I've used HP calcs since freshman year in highschool (but I also took n number of CS classes in which I had to evaluate some expression tree, and postfix notation is very natural and logical way of describing such a thing).

I remember reading a story about that. The frustrated person who knew about order of operations looked for some way to prove it, but didn't have a graphing calculator (which generally follow the rules), so he started up Excel. The consensus was that Excel is broken.

People don't like to learn new stuff it they don't have to; since they're taught infix in school, they prefer infix calculators and thus they sell much better.

Four-function calculators don't do precedence because they merely do stacked equations(ie, it's already forgotten the LHS of the equation by the time you hit '*'); a calculator that doesn't do calculations on-the-fly(like the aforementioned TI-8Xs) will actually get the right answer(I believe scientific calculators are this way).
