Recommendations for RPN Calculators?

sg3000 asks: "My trusty old HP 48S graphing calculator, that served me since engineering school, seems to be giving up the ghost. I haven't used it in a few years, but recently I put new batteries in it. It works, but it makes a loud static/white noise sound when it's on. The noise is not as noticeable when I hold it, but when I set it down on a hard surface, it's really loud. Then it sucks the batteries down incredibly fast (I put new batteries in it, and two days later, they were drained). Any suggestions on what I should buy as a replacement?"

"I'm in graduate school now, and since I'm taking an accounting course, where they don't want us digging out our laptops during a test, I need to buy another calculator. I'm a big fan of reverse polish notation (RPN), so I'd prefer to get another HP calculator.

Do companies still make calculators? I'd love to get another HP 48, but I'm not even sure if HP even makes calculators like that any longer -- on their web site, they're all cheapo-looking single line deals. I've read about something called an HP 48g, but HP has nothing about it on their web site."

    Looks like Microsoft is really taking off on the 64-bit front, check out articles around the web. I wonder what Linux is doing here? Have you guys even thought about 64-bit computing in your Linux OS? Cause it looks to me like Microsoft is going to be way ahead if it makes something that is twice as fast as your Linux thing.

  2. Trolls need love too by Anonymous Coward · · Score: -1, Offtopic

    I'm sure this will be controversial, but trolls need love too. In fact, trolls probably need more love than your average slashbot - slashbots get positive reinforcement, after all.

    There. I've stated the painful truth: trolls need love. Now let me tell you why.

    Most of us were abused as children, or are being abused now, or have suffered mightily in some way. We have self esteem problems, we don't have confidence, we don't feel loved. We want positive attention and all the things "normal" people have, but we feel like we are unworthy of it.

    An old saying rings true here: "If the only potato chip a hungry child can have is a soggy potato chip, there is nothing more important to that child than the soggy potato chip." Well, that describes us trolls perfectly. We are hungry for attention and all we know is that we do not warrant positive attention, so we type "fristus postus" and post goatse links and shoot for the negative potato chip of a (-1 Troll), or a (-1 Flamebait). Off-topic and redundant mods are like half a soggy potato chip - just enough to whet the appetite for more.

    So do the world a favor. end the cycle of abuse. Mod one troll - just one - up, and you will be rewarded for life because you gave a hungry child a dry potato chip. Share the love, won't you?

    A guy in a bar leans over to the guy next to him and says, "Wanna hear a Polack joke?"

    The guy next to him replies, "Well, before you tell that joke, you should know something. I'm 6' tall, 200 lbs. and I'm Polish. The guy sitting next to me is 6'2" tall, weighs 225, and he's Polish. The fella next to him is 6'5" tall, weighs 250, and he's Polish. Now, you still wanna tell that joke?"

    The first guy says, "Nah, I don't want to have to explain it three times."

    Three men are traveling the Amazon, a German, an American, and a Polack, and they get captured by some Amazons. The head of the tribe says to the German, what do you want on your back for your whipping? The German responds, "I will take oil!" So they put oil on his back, and a large Amazon whips him 10 times. When he is finished the German has huge welts on his back, and he can hardly move. The Amazons haul the German away, and say to the Polack, what do you want on your back? "I will take nothing!" says the Polack, and the Polack stands there straight and takes his 10 lashings without a single flinch. "What will you take on your back?" the Amazons ask the American, who responds "I'll take the Polack!"

    The manager of a prosperous whorehouse in Warsaw one night found to his dismay that he was short of girls for the evening's entertainment. Thinking quickly, he dashed out and bought several blow-up dolls, figuring that, given his average clientele, no one would know the difference.

    Soon he ushered a customer into a room that housed one of the new lovelies, assuring him that he was in for an especially good time. When the customer came out of the room a little while later, the manager was waiting eagerly in the hallway.

    He winked at him and asked, "Well? How'd you like her?"

    "I don't know what happened," said the customer, shaking his head. "I bit her on the tit, she farted, and flew out the window."

    Two Poles walk into the post office and the first thing that catches their eye is a bunch of "Wanted" posters, in particular a shot of a mean-looking black guy beneath a banner that says "Wanted for Rape."

    A Pole and a Jew were in a bar watching TV when the late-night news came on. The lead story showed a berserk woman poised on a window ledge eleven stories up. "I'll bet you a hundred bucks she won't jump," said the Pole to the Jew.

    "Deal," agreed the Jew, sticking out his hand a few minutes later when the woman plunged to a gory death. The Pole sadly forked over the money, only to look up in surprise as the other fellow tugged on his sleeve and offered him his money back. "You won it fair and square," he said, shaking his head.

    "Not really," admitted the Jewish guy. "I saw it all happen on the six o'clock news."

    "Me too," said the Pole, "but I never thought she'd do it again at eleven."

    i've got a ti-89 and i can't complain, it's hands down the best graphing calculator i've used. It's fairly easy to use but also has tons of features that will keep you busy for months figuring them out. there are many applications you can download for it with the USB graph link as well

    Not true, its reverse polish, not un-polish. What if what makes up polishness is the metaphysical equivalent of a palindrome?

    But I have to tell this story. My mother, who's being using office machine since FDR's day, learned to use pre-electronic calculators, with purely mechanical logic. For obvious reasons, these were all RPN. (If you can call simple strings of very basic arithmetic functions "notation".) When she got her first electronic calculator, I had to explain to her what algebraic notation was!
