I think this is a satire:<p>* The survey lists it's purpose as identifying trends in software development. Hardly, as this will outline just what a small subset of trends on HN (and HN is just a tiny, itty bitty subset of all softwate development). Since HN is primarily web and mobile development, you won't learn about any trends in game development, for example.<p>* 'Unbuntu' listed as an Operating System. Misspelling aside, Ubuntu is not an operating system.<p>* GNU/Linux not listed as an operating system. Especially among developers, it's a popular choice and i'm surprised to see something like ChromeOS listed while GNU/Linux isn't.<p>* PHP and Javascript listed in both "alternate technologies" and in programming languages.<p>* MySQL but no other databases. I'd venture a guess to say that Postgres is just as common among HN users, if not more common, than MySQL.<p>* No blackberry under mobile phones while Symbian and WebOS are listed?<p>* Minix as an operating system..?<p>* Only two web frameworks listed under additional technologies. Not the biggest problem, but a bit funny.<p>* I'm unaware of Ada being used for anything currently.
