What do you mean? I used it to solve a nasty impedance network for the real and imaginary components yesterday and the solutions were accurate.
Edit: Maybe it's just good enough that people treat it as a tool and see no need to market it. It consistently has worked fine-ish for years and is useful at what it does.
- GeorgeTirebiter 5y agoCould please share your query / code to do this? Seems like it would make a good Example. Thanks!
- neltnerb 5y agoThis is for two pairs of R/C in series ( R||C + R||C ). Real: https://www.wolframalpha.com/input/?i=Real%28+%281%2F%281%2FR1+%2B+%28i*2*pi*f*C1%29%29+%2B+1%2F%281%2FR2+%2B+%28i*2*pi*f*C2%29%29%29%29 https://www.wolframalpha.com/input/?i=Real%28+%281%2F%281%2F...

Edit: Sorry, I don't know how to make the search query text show up since it has special characters, probably best to just use the links to see the query.
- zandorg 5y agoMy meaning was just that I saw it sometimes referenced on HN, but I haven't seen it mentioned for a while now. Hence my search and results showing 8 years since. I guess what I should be doing is looking at the Alexa ranking of Wolfram Alpha.
- dylan604 5y agoThey're just serving up answers which is boring to HN readers. Where's the drama in collecting data privately? Where's the drama from censoring results? No drama == No interest? Gawd, I have become cynical.

- pvg 5y agoYou should search comments, rather than stories. It's very regularly referenced in HN comments, often for calculations, sometimes in other contexts. https://hn.algolia.com/?dateRange=all&page=0&prefix=false&query=wolfram%20alpha&sort=byDate&type=comment https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...
- asxd 5y agoI appreciate the conversation around WA this Ask HN has started, but yeah you've basically completely answered the original question by pointing this out.
- zandorg 5y agoFair enough. I was definitely searching comments (not stories), but I might not have filtered by Date, hence the lack of recent results.
- xeeeeeeeeeeenu 5y agoSorting by popularity has been broken for years because comment scores aren't public any more.
