I try to reserve such engagements similarly, or for those who've just flat out attacked the people trying to help them (like JJ).

I tend to be with you guys. I've been a beginner at a lot of thing that I wound up being pretty good at later. These are things that I enjoy immensely (music, racing, etc.), and getting constructive encouragement from those who've gone on before is far more useful than hostility. That being said, in this group there's a balance to be had for not opening the door too wide for those who want their homework done for them, or every little technical fantasy analyzed, or whatever. I'll admit to having responded more roughly than I should have in some cases, and I do think the tone here gets pretty bad sometimes.

no, don't send me no charity cases. most of the time when i see a panhandler in Cambridge or Boston (or NYC when i get down there), i walk by and ignore them. once in a while, i toss them change, only if i feel like it. i don't stop there and make a considerable effort berating them. compared to before, have you guys noticed how little i post here anymore? my attitude is; if i have nothing to add, or if there are no fun little jollies to be had, or if i have no idea what the answer is, or if i don't feel like it, i don't bother. *sometimes* i feel like it and i bother. and fewer of those times, i end up writing a small treatise here (because that's what would happen if we were in personal conversation and such a subject came up, pity the poor people who are trapped and have to listen - sometimes that happens at an AES thing or in a work context). sometimes i've taken pleasure going after and taking down a pompous and arrogant person here. hell, if we get another one, i might just pile on and get in a few licks myself. but beating up newbies is just no fun and when i see such happening in the playground, i cringe. r b-j

Robert, I am more than a little puzzled by your complaint. This is definitely not a case of some hapless newbie being monstered. Rune posted a couple of short, very relevant questions that went to the heart of the newbie's problem. Possibly the newbie misunderstood the intent of the questions, because he replied: "If you want to help, by all means do so. If not, try to find something better to do than what you're doing right now. And yes, it does say so in the book, as the authors are windowing a "desired impulse response", most of the time corresponding to a bandpass filter, so said impulse response is infinite. If you want more info about the book, you can read it. Otherwise, shut the fuck up." Rune's response, to abuse hell out of him, was natural and understandable. I was also highly entertaining. Regards, John

I concur. I haven't lurked on comp.dsp for quite a while. I recently returned, only to find that 1) the SNR has gone down (spammers), and 2) the /tone/ has gone into the toilet. I mean, I understand if you're not interested in doing someone's homework, but FFS, it escapes me why someone would expend the energy to be such a dick about it? Rick Armstrong

It's often the newbies who start it. It's sometimes is if you toss a beggar a buck and he berates you for his paranoid impression that you sneered while doing it. We were collectively berated one time by someone who didn't think his question was answered completely or promptly enough. He threatened to report us to the management for not doing what we were paid to do. The exchange between pinkisntwell and Rune is an example. Rune was civil long after he couldn't be faulted for being otherwise. Pinkisntwell was too pigheaded (or swell headed) to see that Rune was guiding, not deriding him. It may be embarrassing to learn that one is completely wrong, but that'd no reason to lash out at the messenger.

Hi Jerry,

> The exchange between pinkisntwell and Rune is an example.
So, I re-read this thread and I see that I've picked the wrong thread to bring it up. Still, it seems like I've seen a lot of this sort of exchange: confused> Oh, by the way, since the data is not cyclic, confused> I can't do Fast convolution via DFT not_confused> IDIOT! or no_clue> So, I don't get it... dsp_pro> YOU'RE A BIG STUPIDENT! It just seems like the tone here has dipped toward "schoolyard". Rick Armstrong
